Meticulous, Detail Oriented, Personable, Fair Pricing and Reliable, When we decided to re-side our home with James Hardie siding for fire prevention we went to their website for contractor recommendations. I think 3 came up in my area of Pine Valley in San Diego County and I had all 3 come out to give me a bid along with 2 other siding contractors that could install Hardie Board. One bid was high, 3 bids were comparable and one was low. Turns out Mike and Jesus, owners of CertEx, installed our windows with another company 12 years ago but has since started their own company. I didn't choose CertEx because I worked with Mike and Jesus in the past. I chose them because they didn't blow smoke up my ass like other "Approved" and "Elite" contractors approved by James Hardie. I chose them because their price seemed fair. It wasn't high or low. I chose them because my gut said, "You can trust this contractor". Guess what? I was right. The team did an amazing job. So meticulous. I can't get past that. They did not skimp or cut corners. Their attention to detail was beyond expectation. The workers at my home were Carlos, Arturo and Pumba. They were great!!! Such great workers. If I didn't respect CertEx and their workers as I did, I'd try to poach them for my work because they were amazing. Thank You CertEx and all workers involved. Your work was point on. Exact. It doesn't get better than this. I'll update the "after" pictures once paint, lights and chimney wrap is installed. Thank You CertEx. Your work is amazing as is your employees. read more

My house was long overdue for a facelift and I had such a great experience working with CertEX! Mike and Jesus did multiple walkthroughs with me upfront to make sure they clearly understood what I was looking for and that everyone was aligned before getting started. They were also really flexible with my schedule, which made the whole process much easier to manage. The whole team was kind, professional, and easy to work with throughout the project. In the past, with other contractors, bringing up issues was never easy. Not everything always goes accordingly to plan. However, with Mike and Jesus, anytime I raised a concern or if a small hiccup came up, they addressed it right away, which I really appreciated. It's very clear they value their customers and take pride in their work. They also coordinated well with other contractors who were on-site working on separate projects, which helped everything move along smoothly. In the end, the results look great. Our house turned out exactly how we hoped, and we've been getting a lot of compliments from neighbors and friends. The quality of the work speaks for itself. Overall, a really positive experience and I'd definitely recommend my new besties at CertEX! read more

If I could give 100 stars, I absolutely would!! From start to finish, working with CERTEX was truly such a positive experience. I needed to replace an old aluminum sliding door, nine single pane windows throughout my home, and replace the siding above my garage. I received multiple quotes, but CERTEX immediately stood out. Not only was their pricing competitive and inclusive of quality materials and a solid warranty, but I genuinely felt comfortable and confident moving forward with them. Mike, the owner, is truly one of the good ones. He is honest, transparent, and incredibly easy to talk to. At no point did I feel pressured or upsold. He took the time to walk me through everything and made sure I felt confident in every decision. You can tell he genuinely cares about his customers and takes pride in doing things the right way. The transformation to my home has been amazing. The new windows completely changed both the exterior look and how the inside feels. It is brighter, cleaner, and so much more updated. The siding repair also made a HUGE difference to the front of the house. Everything looks modern, polished, and cohesive now. It honestly made me fall in love with my home all over again. I met with Mike's business partner, Jesus, every morning, which I really appreciated. One of the things that meant the most to me was his communication and attention to detail. Jesus kept me informed on when they were arriving and what the plan was for the day. I never once felt out of the loop. Their crew was professional, respectful, and incredibly kind. (Big shoutout to David, Jose, and the rest of the team!) They cleaned up at the end of each workday, kept everything organized, and treated my home with care. Truly an amazing group of professionals who exceeded my expectations. When it came time for the final invoice, there were absolutely no surprises. It was exactly what I was quoted and signed for. If you are considering window or siding work, or any of the other services they offer, I 110% recommend CertEX. You will be in great hands and will not regret it. I enjoyed the entire process and absolutely love the results. I am already looking forward to having them back for more projects. read more

I'm happy to have found this place to replace my windows and sliding door. The process is simple, from start to finish. First, Mike came over to check the windows and the sliding door that needs to be replaced. He discussed my options, and I don't feel pressured to get the most expensive; instead, He focused on what's right and what I need for my house. No aggressive sales pitch for add-ons. After that, he gave me a decent fair quote that doesn't make me feel like I am buying a new car. Since I lived in a condo, the only time it took was getting HOA approval. Once I got approved, I called Mike back so I could sign the contract. He placed the order, and a few weeks later, Jesus (Mike's business partner) and his team came over to install my new windows and sliding door. Shout out to Jesus for explaining what they are doing, and his team double-checking their work to ensure everything is sealed and clean. All I can say is that I am happy with the overall experience; the service is fantastic, and the brand/product they installed is great (double-pane glass doors are amazing). Would I recommend Certex Construction? Definitely yes! Picture to follow :) read more

What a smooth and fantastic experience! While the majority of the home was stucco, the house needed most of the wood fascia and other wooded structural pieces repaired, before repainting. I don't live in the area, but this was for an elderly family member who I help, and it's always tricky to find good people when you don't live there. I found CertEX on Yelp and Mike responded immediately. And I couldn't have found a better contractor. We got a few quotes and his was competitive and we really enjoyed his clarity and style. This is a firm that communicates well and is beyond professional. No hard sell. Very through contracts and addendums. From the initial consult to quote to project start, it was smooth and well documented and they keep you in the loop. And they'll paint the exterior when the repairs are done! I didn't have to find a separate painter, it was one and done! (And done right.) Jesus runs the daily crew, and they are polite and considerate too. I have worked with a fair amount of contractors for rentals and repairs on personal properties, and this was the most organized and proficient project, bar none. Happy to recommend and highly suggest you get a quote from them. read more

Our home originally had old aluminum siding and was long overdue for an upgrade. Certex Construction completely transformed it with the installation of James Hardie siding, Anlin windows, and lifetime paint, and the results are beautiful. Mike managed the entire process-from the initial quote and contract to permits and construction. He is extremely knowledgeable, communicative, and truly prioritizes customer service. Jesus and his crew ensured the project ran smoothly from start to finish. They did an excellent job with the demolition, siding and window installation, drywall, and painting. The team was always punctual, hardworking, and respectful of our home, cleaning up daily. They even worked extra days to stay on schedule, which we really appreciated. While construction projects can come with challenges, Certex Construction delivered quality workmanship and addressed any issues promptly along the way. We're very happy with the outcome and grateful for the entire team's effort. read more

I was very impressed throughout the entire process. Mike explained all of my options without being pushy. I called months later to move forward and he still honored his price. Once the project started, I was always texted to let me know what the next steps were. Jesus and the crew were always letting me know when they were arriving and when they were leaving. My James Hardie siding looks incredible and I already referred my neighbors! read more

Certex did a great job with our house! Our goal was to fire harden our house, so we replaced wood shingles with fire resistant siding, covered the eves with fire resistant material (Hardy Board), and installed new fire resistant vents (Vulcan vents) to replace existing vents. We then painted it all with a fire retardant paint. The house looks great now, and we feel much safer should any wildfires come to our area. Things I really appreciated about the Certex team: 1) Their bid was reasonable and transparent: there were no hidden surprises or unexpected change orders 2) The workers were polite and did a good job cleaning up after themselves each day 3) Mike and Jesus did a great job communicating with me through each step of the process and things went to schedule 4) They paid attention to the little details in terms of trim, paint, etc 5) They guided us well in terms of design aesthetics and what would look good. We are very glad that we worked with them and we would definitely recommend them. read more

Our home was in desperate need of new windows, structural repairs and exterior paint. Mike and Jesus gave us a very competitive quote, and advised us with questions we had regarding materials, repairs and updating the look of our home. They were never high pressure which I appreciated. Their crew were always on time, did meticulous repair and prep work, they were very friendly and very considerate of us and our neighbors. The quality of our windows and exterior paint are amazing! The windows block out sound and the exterior paint/coating also makes our home more energy efficient. My husband and I give Certex 5 stars and the highest recommendation! read more

We needed the side of our house painted which included some old 1930s windows. Mike and Jesus were a great team, both professional and always smiling. Always on time and reliable. They brought in a team that got the job done expertly and fast. They paid meticulous attention to details and the old windows were taken care of with kid gloves. The painting looks fabulous! We have a few more exterior projects and will be reaching out to CertEx again. We were more than impressed. read more
