Had one of your "marketing" rep come to my house for estimate today. I was upfront with him that i had a few quotes from different companies and also some coming out this Saturday. He ask if he can take a look at one of the quotes i got and I showed him because I wanted to be transparent. He ask to take a picture or send him the quote through email i said no but he wrote them down anyway while looking at my phone. It bacame awkward and very shady at that point. After 5 minutes of him reviewing and writing the quote from my phone. He is now insisting me over and over to give him a price thats best suited for me to close the deal right now right here! I was pressured at that point. He suppose to give me his presentation and deals and what not but it went from an estimate to an interogation. I felt like i was buying a car! whew! At that point since i did not want to give him how much my project should be because i literally dont know, i have no idea this is why homeowners get quotes right??! So anyway after that He didn't even bother to measure our windows, didnt bother giving me his presentation, ddnt bother giving his estimate pricing deals or anything! He literally said "have those companies come out this Saturday and we will be coming after them." shook my hands turned around and left! I was like.... What the heck just happened! That was awfully awkward! haha but anyway thanks for this initial 15 mins visit experience. I definitely learned a lot! read more

High quality and efficient workmanship. The crew leader introduced himself. He put me at ease by letting me know they are here to make me happy by replacing the windows. He was right. In about 6 hours, all was done. They cleaned up, took care of business and left. I woke up today in a NEW HOME. Photos of one of the windows being installed read more

Energy Core replaced most of our windows in September with high quality Anlin windows. We felt the price was a good value for the final product and features. The process was very efficient and didn't damage the stucco. From the sales meeting to the installation, the communication was excellent and the process very smooth. The installation crew was outstanding and skilled and did an amazing job, cleaning up along the way. Can't wait to call them back to get our remaining windows replaced. read more

Eric and Taylor were very helpful and informative when it came to choosing our new windows and backyard door. Eron, our project manager was also professional and helpful when it came to answering our questions. Installation day came and the workers were polite and efficient. Cleaned up after themselves and left no mess behind. Hauled away our old windows and backyard door and left us with brand new beautiful windows which upgraded our home immediately. A month after having the windows installed, there's a noticible difference with how cool it stays inside despite how hot it is outside. Amazing transformation on my home and will have to get in contact in the future for some patio work. Thanks guys!! r/sm read more

You have no idea what a big deal getting Central air in a Mexican household is. My mom loves to suffer through the heat , Not me ! I've literally stayed in bad relationships for air-conditioning and Showtime (LOL) Mike and his three man crew knocked it out in three days. Our house was full of challenges and they work through all of them with a smile.We got along with them so well the last day we made them homemade vegan tacos made with fresh Handmade tortillas . He put everything away nice and clean and worked around all of our stuff . I would give them more stars if I could. Thanks guys #FeelingLikeFonzie #BecauseI'mCool #Literally read more

Got windows installed on my house and after the installation I noticed that standing near the windows I didn't feel the heat from outside like old windows. The noise has been significantly quite and the house stays cooler even with out having the ac running constantly. Dealing with energy core was also very easy since they kepted us updated on what was going on and when the installation will be started. read more

After a heavy rain storm, I noticed a great deal of roofing granules on my driveway. My handyman was doing a job for me so I had him go up on the roof and inspect it and take pictures. I couldn't do it myself because I'm disabled and cannot walk. What he showed me was scary. The shingles were practically bare. I helped my father put up this roofing 35 years ago when I was a young man.i went online and there was a site that could give you a rough estimate using Google earth to asses the size of your roof. After that, I received many sales calls. I chose one that fit into my schedule. ENERGYCORE CONSTRUCTION. Their salesman came by and did an inspection and asked if I had any leaks. I told him no and he was very surprised, because he said the roofing was in really bad shape. He showed me pictures and I agreed, it was toast. He was very patient and showed me the process and materials they would use very thoroughly. Owens-Corning top of the line materials. 50 year warranty. Explained how they would remove an old swamp cooler and patch the hole. Replace any wood found in bad condition, replace ALL the drip edging and any fascia boards not up to their standards. Their crew showed up on a Tues at 7 am and stripped the entire old roof in 4.5 hours and cleaned everything up. You could not tell any roof stripping was done because they were so thourogh with their clean up. The next day (Wed) was inspection and on Thurs morning, work began. Then after 2 hours or work a giant curveball was thrown our way. The power went out in the entire neighborhood!! The crew did everything possible, but with no power, their air compressor did not work. So no nailing of roofing couldn't take place. They did what they could with their battery powered tools but their pneumatic nailers were down for the count. The power was finally restored at about 5pm. The crew got to nailing immediately. They worked until it was just to dark to do quality work. They were back early the next day (Fri) and completed the job. Just in the nick of time because it rained that night. The salesman was freindly, considerate and explained all aspects of the job thoroughly. The crew was fast, thorough and left the area so clean, you'd never guess a major job like this was completed. A couple of days later, another team member came by for final inspection and to finalize payment paperwork. I received a pretty good discount for using their top of the line materials and the price was very fair. Overall, it was an easy and great experience. You hear tales of shady contractors so I was apprehensive but I was worried for nothing. If you are I need of new roofing, I can highly reccomend ENERGYCORE CONSTRUCTION based in Anaheim CA. read more

The quality of the service was superior to other contractors we have worked within the past. It was refreshing in a time where customer service is virtually nonexistent. The crew showed up on time had professional attitudes, were very efficient and even made the job of install 13 windows go smoothly The quality and look of the windows give our house great curb appeal. We especially like the look of the front three windows. The value far surpasses what we expected, and it makes a difference in the outside/foot traffic noise. We live on a busy street with a lot of noise. The windows make outside noises a thing of the past. We would highly recommend Energy Core Construction Anaheim and Anlin window for your next project/upgrade. read more

These are the best windows ever! Our old windows one would hear everything happening outside. We live on a busy street. Lots of traffic noise for a residential area. Closed up due to a recent heat wave. I don't hear any noise. For the first time ever our house it quiet. The outside noise stays where it belongs...outside. Zack McKay great guy. He will treat you well. They dealt with getting our HOA approval permit and then the offical city one. Even with our need for more custom windows, from ordering to installation was fast. Only 8 weeks. Zack is the man you want. read more

I wanted to thank the staff of this company for the extremely fast work on my new roof, finished in only 3 days. By name; Zach and Rick came to my door initially to show their product and I signed up; Taylor was my go to contact for payment setup and various questions I had, and we did the final walk through inspection. He gave me some photos of the before work condition as this was important to me, and the performed work photos. Even a video of the work. Thank you to the roofers for their fast, professional work. Here, I can only name one of this personnel; Gilberto, who I talked to and of whom I asked the questions as they came up. I apologize to the other roofers as I didn't get their names. Be assured that you are included in my appreciation. read more

I can't say enough good things about the work that was done and the people at EnergyCore. Everyone from the Sales Rep to the Project Manager was top notch.

Also all of the behind the scenes work it took, I know you guys put in a lot of hours on this one. We are forever greatful with the job all of the crews have done to bring this idea to life!!

I absolutely love my new windows and sliding door. My project manager Eron Macias made sure everything was completed correctly. I had 21 windows including the slider, and many windows were huge. I was actually surprised at how quick the windows and sliding door were made and installed. I was worried about my shutters but they assured the shutters wouldn't need to be removed to install. Everyone wore masks during the appointments and install, and were very courteous. I recommend this company if you need any of the services they offer. Thank you Eron for following up through the entire process. read more

Job well done by Taylor, Dean, Danni, and the installation crew. I'm very happy to say everything exceeded my expectations. I am not an easy customer to please, so I really appreciated the patience, time, and effort put forth. These doors and windows truly block out the unwanted noise and elements as promised. I look forward to completing the rest of our home. Bravo!!! They really did an amazing job. I really trust their collective work ethic. read more

Working with Landis was an absolute pleasure. He was very informative about the windows we were purchasing for our house. We were sold. Our new windows were recently installed (which was within the estimated time that had been projected to us when we purchased) and we love them. The windows were installed and everything was cleaned up within 5 hours. I was pleasantly surprised the installation process was so quick. We can definitely tell the difference between the old windows and the new ones. House definitely stays cooler longer. Very good product. read more

Energy Core Construction rep Zach arrived on time, and by the end of his visit we knew this was the company for us. With Zach's help we chose the Onyx Black Owens Corning roof with the 50 year warranty, and it's beautiful!! We love it, and yes, right away I noticed subtle differences. Besides being absolutely beautiful, the house was somehow quieter, even when the Santa Anas came through. My husband laughed when I told him, but he had to agree when a few days later it was raining and we had no idea until I peeked out the window!! I remember hearing everything going on outside with our old roof, but this one... nothing. I smile every time I go outside. I've sent pictures to family members that had been nagging us to get a new roof and they love it too. As for the construction phase- sadly, we weren't here. The roof was scheduled for May 2nd, but we had been waiting since Feb for asbestos removal for bathroom repair, and got the call to leave April 28th. We were gone 8 days, and when we pulled into the driveway we saw no roofing construction debris, everything was just as we left it, perfection!! Yesterday a rep named Mark stopped by, took some after photos, and again asked if we were satisfied with the work they did, and yes, we are. I highly recommend Energy Core Construction, their team handled everything start to finish, and kept us informed along the way.  I had no idea so many steps were involved with installing a new roof, but they do, and you can trust them to do the job well, respect your property, and follow up to be sure you're satisfied with the job upon completion. read more

The crew did a flawless and fast job installing the windows! Eron was the project manager and he was really nice! Highly recommend!

Fresno, CA Office From sale to final completion walk through, the entire process was smooth and easy. Zach and Alan started the process with demonstrating all the benefits of upgrading to the Del Mar Luxury vinyl windows. They are energy efficient, provide sound suppression, easy to clean, and offer a double lifetime warranty. I was sold. Eron Macias, Project Manager worked around my schedule to come out and get all the measurements for the 11 windows and one 96x96 sliding glassdoor. I noticed one of the outside ornamental windows wasn't included and he measured and got that one added. Everything was ready to install in about 2 months. Shawn and his team arrived on time, were friendly and professional. They explained the process of removing the old windows and installing the new ones. They did this over 2 days, cleaning up as they went along and removing all the debris. They demonstrated the additional safety features,especially the large deadbolt for the slider. The energy efficiency is evident from day 1 and all the windows and slider look amazing. Eron then came back out and did a final walk through. I had one window in my master bath that I decided to have the windowsill raised. The wall was built up but not finished with sheetrock and texture as i had thought it would be. Eron made a quick call and someone will be out to complete that. I appreciate that customer service greatly. I know I made the right choice to upgrade with Anlin windows and doors and highly recommend Energycore Construction. read more

ECC are Pros! Art and I needed more than roof repairs on our casita. The roof needed to be replaced after 20 some odd years of patching here and there. Energy Core Construction did a beautiful Paint/Coat on a neighbors home and they were very happy with the work, so I called them. From sales, to project management, to roof tear down and install - the end to end process was unbelievably professional, timely and they kicked butt. It is pricey, but ECC also offered a decent lender program with no early penalties if you decide to payoff the loan. We feel blessed to have come across their great service. A&S read more

Excellent job thru. We decided to do it in two batches, upstairs windows first, sliding doors downstairs later if the windows were nice. Well, we're definitely going for round two! In April we ordered our windows, got HOA approval easily. Kenny came to measure exacty. It took about a month and half to get the windows custom-sized from the factory, Amlin dual pane triple low-e, can't even fee the sun heat thru them - won't bleach the floor. Installation was done in one day mid June, and some small scratch in the screen was fixed one week later under warranty. read more
