Efficient Construction did a great job with my coating work done to home. Isaiah and Mike were great to work with as well. Would recommend. The preparation and paint crew with Juan was absolutely amazing, we had a lot of stucco falling off, our Fascia was old and chipped and was fully replaced since the original wood was damaged. They painted our security doors, our garage, our cracks were caulked and sealed. Juan and his team were amazing and and finished our multi family home. I would recommend reminding the crew to prime an area prior, to ensure you can see the true color of the paint. I would definitely recommend. read more

The team we got from this company to replace our roof went above and beyond! We were blessed to see all their hard work, and they finished quickly, attending to every detail that we mentioned or they noticed. Ryan's leadership was thoughtful and professional. Thank you to Mark, and George and too many to name. Jose who did the finishing around the HVAC was an amazing problem solver. We highly recommend this crew. Now we have the peace of mind that comes with a solid roof before El Nino season. An answer to prayer! Thank you! read more

Mike Kim was the project manager for the installation yesterday of a large picture window on the front of my house. He oversaw the project from beginning to end. The two workers who did the work were efficient, friendly, and respectful of my property. When I'm ready for another project, I would certainly go first to Efficient Construction and ask for Mike Kim. read more

From the minute Mike Kim walked through our door, shook hands, we knew we could have a good conversation. Mike went through the details in way that we could understand. The roof job including our solar panel removal and reinstallation went perfectly. Mike was in touch with us every step of the way. We are extremely happy and if we or friends need future work, we know who to call! read more

Efficient Construction comes and gives a good story about their work and efficiency. They promise you exactly what you ask for. Once the work gets started, all of these promises change. The financing, the work order, the materials, the whole scope of the work. It will take much longer than you are told it would take. If you need corrections, you'll never get them. Those in charge will continue to lie about coming to make adjustments to no avail! I was told that my finance percentage was 10%. Once I was billed, I found out that the percentage was 12.9%. Every aspect of this project was a lie! read more

Great service. They left the property super clean. We love our new roof. Special thanks to Jose, Luis and David.

I just had this company finish a paver job, the work is good but the sales and contracting team is horrible and do not honor anything that they tell you would be done upfront. I asked the sales rep to measure the space to have an accurate SQ footage he didn't do it, I asked him if he needed a tape measure several times he just walked around with his phone an took pictures. I would not recommend them at all for anything and if you are in negotiations with them ask for everything in writing before you sign any contract, no not sign until you have it all on a legal document. Not a good construction company just a lot of co-artist. The sales rep give the talk about how great a deal it is when at the end you will get overcharged for less work. read more

Came to give a roof replacement estimate were very nice but after hearing their pitch for an hour and a half I asked for the price. They became very pushy , wanted me to decide on their company to do the work right then! Just as a car salesman would say "the deal was only for that time ". Of course I needed other estimates and time to decide . This pissed them off and the " project manager " Arman ripped the estimate review in half. Very unprofessional behavior!! read more

This company came walking my neighborhood asking to give quote on my roof. I was very up front and said I'm not looking to do anything too soon but if you want to give me a quote go for it. They said quote is good for two years. Set up an appointment, young kid comes out gives a whole presentation. Nice kid. Leaves me a price on a chicken scratch piece of lined paper. I asked for an official quote. He said they would email it to me never happened. Another guy calls says kid didn't know what he was doing and thinks he can give us a better price. Sure. Another guy comes out knocks the price down makes a phone call knocks price down again. Told him I want to shop around. Makes one last phone call to "the owner". Price is now down $6k+ from original price. Now pressured into a take it or leave it offer. Has to be tonight. Declined offer and salesman tone changed. Still didn't get a written quote. Just felt like a car salesman approach. Left my wife and I feeling like not someone we want to do business with. Don't fall for their cheap sales tactics. read more

Efficient construction doesn't wanna honor the contracts.They made with me for and adu. They wanted me to pay more after they efficient construction gave me the price for the job. The contractor named is Cesar told me, we have to renegotiate for more money if not to for get it. Why would I renegotiate to pay more money.

The crew was great and the roof looks great as well I'm very happy with the outcome. Thanks to efficient construction

I rate them 0, an if I could I would rate them lower, this is the worst contractor company that I've ever used, DON'T WASTE A DIME with this HORRIBLE UNPROFESSIONAL COMPANY, Vincent Velarde (Project Manager) @ the Gardena office, was great until after they received PAID IN FULL ($9500) before the work was completed, it's been nothing but a lot of BS since 2024, they keep giving me the run around, they didn't finish the work, they don't honor their contract, they play with ALLL MY CALLS by giving me a fake service number or just hanging up, and MY PROMBLE STILL ISN'T SOLVED!!! I guess it's Lawyer time maybe then I can get something done. read more

The quality of the work is really good, with quality materials used. They definitely are much higher priced than others, but they do quality work and communicate well. You need to be mindful of their sale techniques, they jump on you and trick you into getting things quickly. They assured us that there was a leak in the roof, but after signing the contract we found out from neighbors that the roof was done less than 10 years before. Be cautious, but if you do need the work done it will be high quality read more

I have lived in this house for 36 years, raising my family here as a single mom. For many years I dreamed of making upgrades, but I was always afraid to take the leap, especially with so many contractors constantly urging me to redo the roof. It never felt right, and the prices were never manageable. Efficient changed that. From the very beginning, their team -- Aaron, Alvin, and Anthony -- gave me the education and confidence I needed. They explained the products thoroughly, walked me through the process step by step, and were completely transparent about what was worth investing in and what wasn't. That honesty showed me they truly stood behind their superior products, something I didn't see from other companies. The sales representatives who came to the door were also respectful and not pushy. They explained that the estimate they provided could be used now or in the future, which made me feel at ease instead of pressured. Their approach stood out compared to competitors who often felt more focused on making a sale than truly helping. When it came to the work itself, Alvin and Anthony listened to what I wanted and made it happen, while Aaron orchestrated the entire process with care and precision. Over the course of this project, we were able to do what I once thought was impossible: a brand-new roof, a beautiful CoolTech paint job, a custom redesign of our front door and garage gates (which was especially challenging because of settling issues in our older home), updated plumbing for half the house, and even an entirely new HVAC system. For decades we had only an old 1920s floor heater, which they removed and replaced, patching the area with new hardwood flooring that matched seamlessly with the rest of the house. That level of attention showed me that this company goes above and beyond without nickel-and-diming their customers. Most importantly, their financing partnerships made everything achievable. Mike helped me navigate a process that used the equity of my home instead of relying on credit, which as a homeowner with limited credit options was a huge relief. Their prices were truly unbeatable compared to anything I had seen before. With the support of my daughter, I finally felt comfortable moving forward. I am so grateful to Efficient and their wonderful team for making this long-held dream a reality. read more

We were hesitant at first only because I'm not used to door to door sales but we had received other quotes already and ended up being impressed by the clear overview of the project, choices & additional work included in their scope that would qualify for a "green" & energy Effecient roof. The project was managed by Tony, him and his team did a good job communicating, being on time and the quality of their work was great. I already notice a difference in our home being cooler. Best part is they were very EFFECIENT!!! The whole job was finished in 2 days & they cleaned up as if they were never here. Overall I was really happy with the job and would hire them again for other projects. read more

Beware of this company, Especial for "Roofing" they are doing the job not correctly then you on your own, they get the permit of my house on a difference roofing company's License C-39 and Efficient Construction only have General contract License, something is very wrong here! And the Roofer Carlos had been told me he is employee of efficient Construction. I have to hire a difference Roofing company to finish what they "screw up" and send them the bill, they fail to respond to me on my demand letter for the amount of money I spend to fix they screw up I and up to complaint to "California State License Board" and file a small claim to recoup my loss! Following is conversation of C-39 Contractor & Owen Corning Sale Rep & myself: Hey, Rolando, how you doing? It's Johnny What? Johnny, with Roof Bro. Oh, hey. Hey, come here. How you doing? I'm good, I'm good. Hey, I have a question. Um, I'm over here with a client. Uh, he just had it roof install on a couple of weeks ago. They installed the Owens Corning system and uh, but, uh, I'm trying to explain to him that, uh, like the way they did it, they have the soffits for intake. But they installed a rich fan and they installed O'Higgins and then they installed a solar fan. Okay. So, what happens to the warranty when you have all those 3 systems for exhaust? Are they all for exhaust? Yeah, they're all for exhaust. There're enough soffits for intake, but the exhaust is belonged to me originally. Yeah, that's okay. Yeah. Yeah, so if there's ever, um, anything with the shingle or any pollen with the shingle and it's due to ventilation, then that is where the warranty might be avoided. I'm not saying it is, but it might be voided. So, when you have different exhaust systems, it could complicate the ventilation system in the attic, because you would, so you're supposed to have only one intake and one exhaust. So, uh, or one type of intake which you do at the soffits, and then one type of exhaust, which you have, uh, three. at this point. So, what you would, what you could do is cancel some of them out and the exhaust? Uh, and then you should be able to have a proper airflow in the attic space. Okay. All right. Well, which one should I cancel without? It all depends on what you want. You could cancel out the solar attic van. You could, um, cancel out the O'Hagan, um, or you, that's how it's original. So, it all depends on kind of how you want to proceed. Can I have two? Can I can I have exhaust and uh... You could, you could have the attic fan and then one type of exhaust. The only situation that could occur is that when it rains or where there when there's moisture in the air, heavy moisture in the air, the attic fan could suck in some of that moisture. Um, because of uh, Because of the because of because of there being another exhaust system. nearby. So, it could suck in some of that moisture. So, you do want to be weary of that. So, and that's in times when it's about some rain or when it's raining, just make sure that the attic fan. does not turn on. They sell it so long. It's a solar. It's a solar. Yes, yes, yes. So, you just want to be cognizant of that, but at this point, just, you know, exit out, exit one of the exhaust vents out, whether that's the ridge vet or the Hagan. And you'll definitely have proper airflow at that point. So, if I, if I, if I take the O'Hagan now, that should be fine, right? Yes, yes, absolutely. Because right now, I still have the exhaust, uh, solar exhaust, and uh, Vent, and uh, Bridge vent. So, he's got the Bridge vent. The Bridge vent, Yeah, but the solar fan is like almost, it's really close to that Richmond. So that's going to trap some moisture, right? It's going to suck in some of the moisture. Yeah. Yes, that's correct. Okay. Okay. All right. So, it all depends on how you want to do it. You could cancel out the O'Hagan vents if you want to by putting a piece of ice and water inside the attic, or you could take out the whole thing and put shingles over it. So, it all depends how you want to process. read more

We were actually happy when Efficient showed up on our doorstep because we could not remember the last time that our roof had been updated. The representative made a 1pm appointment with us but their sales person arrived much later when we were eating our dinner. Arman checked the wood in our attic and advised all needed wood would be replaced. He provided us with proof of the company's license and liability insurance and status with the BBB, etc. Everything sounded great. They even provided financing and a discounted price. The job took four days, seems quite labor intensive and appears to be done well. There has been one rain so far and the roof has held up great. We have a flat roof so it can be challenging. Prior to the rain, we noticed, we could see light through one of the a/c vents, the roof was installed with blow torches and a hole had been burned in the awning over the back door, the workers used our broom to clean up, voltage wires to our a/c unit and our cctv system were left exposed, the pvc pipe was left directly on the roof, the pvc pipe was disconnected and stained the ceiling in one bedroom after they had removed the old roofing material. To this day, we still wonder why they did this. All the aforementioned items have been rectified except the stain on the ceiling. We reported the damage to the ceiling and have heard nothing and have since had the damage repaired. A city inspector actually signed off on the this roofing job but never went on the roof because there were too many basic things that were done incorrectly like the pvc pipe directly on the roof and the exposed voltage line. We were also home when he was here and noticed he never went onto the roof. Before signing off on the job, Arman and another person visited us looking over our house criticizing our windows advising how much energy we were losing. read more

I grew up in this house my entire life, always wishing I could help my mom make the upgrades she dreamed of. Thanks to Efficient, that dream finally came true, and I couldn't be happier with the results. From start to finish Alvin, Anthony, and Aaron impressed me with their knowledge and professionalism. Their transparency gave us confidence that we were choosing the best solutions, unlike other companies who would avoid the conversation about the products that they utilized - likely because other companies don't use premium/durable materials. Once we moved forward, Alvin and Anthony handled the contracting work with care, listening to our needs and tailoring everything to fit our older home. Aaron coordinated all of the projects seamlessly and answers all questions and resolved customizations needed. I personally oversaw every single project: the new roof, CoolTech paint, redesigned front door and garage gates, plumbing upgrades, and the installation of a brand-new HVAC system after removing our old floor heater. I want to especially highlight that every team I worked with was not only professional but also incredibly kind. They worked swiftly, kept the areas clean and contained, and treated both me, my sister, and my mom with respect throughout the entire process. As a woman navigating projects of this size, I know it can be nerve-racking, but every member of the team made us feel comfortable and gained our trust with their professionalism. read more

Warning: This is a long one. I bought a house in May and and needed contractor work. I guess they saw us moving in and left a flyer on our doorstep. I called regarding a roof replacement and they seemed very courteous and friendly. The man came at the agreed upon time and he said he would come back when my husband was there so "he could give his input" excuse me? I explained that it's my house and I was hiring him, so everything is with me. He went into my attic and never went on the roof! He left me with a brochure and said he would come back another time when my husband was home. Again, bro? I received another call from Efficient. They asked if they could send someone to give me an estimate and I was like "you already did!" I was told that they weren't aware of that and it was probably miscommunication. I agreed to a new guy to come out. Appt was for 3 PM, he shows up at 3:20 and asks for a ladder. Seriously.... You're a contractor coming to look at a roofing job with no ladder??? He said his wife took his work truck and ladder. We offered him ours and he said " guys, I'm so sorry but my kid has a baseball game and I don't want to miss it. Can I come back?" Absolutely not. We told him we would find another roofer and thanks. The next day he shows up at our house announced! My husband was at work and I told him through the ring camera we did NOT want their services and please leave. He proceeded to leave me a long text apologizing and saying he wanted to make it right and now I'm like "are we 17 and dating??" I told him NO again and please leave us alone. I deleted the text and blocked his number. We got a new roofer who did an excellent job. Every week or so I was getting calls from efficient trying to schedule a roof estimate. I blocked you! The roof is done! Go away! Every week they call from number starting with 310-400 and I realized the guy was texting/ calling me from his personal phone and THATS what I had blocked. My husband called the "owner" and told them to leave us alone and never show up at our house or call again. Today I get two new calls. See for yourself... This company is at the very least unprofessional and unhinged. The hidden review is 100% correct. Beware of Efficient Construction and leave us alone! Don't even respond to this review. read more

I would bestow a rating of zero stars if it were possible. I find it difficult to know where to begin. Initially, the two representatives who visited my home to provide an estimate insisted vehemently on the necessity of my husband's presence. Despite my explanation that he works extensive hours, their persistence remained unwavering. Once my husband arrived early to speak with them, they entered our home with a box filled with various items, determined to showcase the extraordinary qualities of their proposed paint. They conducted demonstrations before us in an effort to persuade us that they possessed the finest product on the market. My residence is a modest two-bedroom, one-bathroom house encompassing approximately 750 square feet. After indulging us in a masterclass about their so-called magical paint, which they claimed would endure for a lifetime and safeguard the "bones" of our home, they proceeded to provide their estimate. Astonishingly, they quoted us a staggering $51,000.00 for the painting project. However, upon witnessing our astonishment, they began to manipulate the circumstances. They "consulted" with their superior, who purportedly agreed to lower the price if we permitted them to place an advertising sign in our yard. Miraculously, the estimate was adjusted from $51,000.00 to $39,000.00. Observing our evident hesitation, they suggested that, since we seemed to be agreeable individuals, they would once again reach out to the "Boss" to see if he could offer us any further accommodation. With great enthusiasm, they presented us with a final offer of $31,000.00, claiming it to be an unprecedented price and the best available for the high-quality paint they advertised. After a private discussion with my husband, we resolved to inform the two men that we needed to review our finances and deliberate further on this proposition, expressing our intention to contact them the following day. One of them exchanged glances with his colleague and cautioned that the offer was time-sensitive, indicating that if we chose to reach out the next day, they could not guarantee the same terms. Since we lacked the opportunity to acquire estimates from other companies, their manipulation caught us off guard, and regrettably, we allowed ourselves to be deceived. We are still beholden to the financing for that job. Now, the paint is deteriorating, and the wood is damaged. I have repeatedly called and texted them in hopes that they would come and assess the alarming state of the paint and wood they applied to my home, yet they have ghosted me, providing no response whatsoever. I am uncertain of my next steps. I will share photographs of the inadequacies of their work on my property. I urge others to heed this warning about the company; it is truly a dreadful establishment. read more

I recently hired this company to address the foundation of my house. First they sent the "scout" to look at the area under my house and talk about their accomplishments as a company. Next day or so they sent the "expert contractor" and I informed them I really don't wish to be gouged on the cost of repairs. I was charged $22,000.00 to reinforce the foundation of my home which is less than 900 square feet. I don't recommend this company at all because I then found a contractor that quoted less than $12,000 for the same service. Efficient openly admitted that the cost was gouged and overpriced. You'll feel better about making repairs and upgrades with contractors that are honest. These guys are liars. I was told my house would be jacked up to install studs and posts. That didn't happen. I was told the city of Los Angeles would issue a permit; that didn't happen either. It was a one man job that took less than 8 hours!!! Scam artists, all of them. I paid the money, thank God the young man that installed the posts did a decent job. I hate liars. I hate I believed and trusted this company. Nobody should feel taken advantage of like I do. Oh, and I was quoted another $28,000 to repair stucco. Then they go down to $17,900. Yeah, no thank you. I got another quote for $10,000 but from another contractor. My bad for trusting the devil in the first place. Don't be a victim too. read more

I didn't work with this company. Just the appointment process for a quote. They were so concerned about my husband also being in the present or my brother or whoever I make decisions with. I did let them know that the amout of times they asked that after I have already answered is quite condasening. They then explained to me that the reason is their insurance and if someone was to get hurt in the home with only one person on the title present, their insurance might not cover. This is pretty alarming, as when the acttual work is being done I don't imagine my husband and I would be home. In addition I had a quote from them for similar work a little over a year ago. This quote was astronomically high, it was more than double two other quotes I have recorded. This appointment was an attempt to give them a second chance. Witch didn't happen due to the fact that I was the only one that was home I wanted to find out if they really do over charge or if it was just a mistake. In addition to the high quote, I was also shown pictures of a post in my foundation that had fallen. Since then I had two quotes and both told me that I didn't have any posts that had fallen. So I just had to share. It seems to me, that they push for you to make discussions quickly and without other quotes because they are dishonest. I will not be working with them and I would not recommend working with them without having other quotes first to compare them too. read more

We had a very rough start with Efficient Construction. Their sales person Nick was pushy. No matter how many times I told him that my 81 year old mom is hard of hearing and I that needed to be there when talking about the project, he ended up getting my mom to sign a large contract on a bathroom without me present and somehow got her signed up for a loan that she didn't want. She was paying cash for all her work. I eventually kicked Nick off the project. I would give Nick ZERO stars. However, Cesar and Tony stepped in and managed the job. They did a good job ensuring the project was completed with quality and they took care of canceling the loan that Nick took out. If I were rating just Cesar and Tony, I would give a five stars. Rating the workers, I would give David and Jesus five plus stars for the work in the bathroom. The work on the outside of the house I would give 4 stars. read more
