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!

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.

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.

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.

Before and After Thanks to CertEx Construction  I highly recommend there services.

I was impressed by the team's attention to detail was exceptional. I highly recommend their service. Their commitment to customer satisfaction is unmatched. Thank you

Superior Siding - Idea for new facade

Superior Siding

Ocean Beach, Point Loma

2.5 stars: My siding looks beautiful due to Christian's…read moregreat employees and due to my diligence/flexibility and my major cost shifting techniques Christian's behavior led me to undertake. The process to get to almost the end point has however been pretty awful. I have read the older reviews and am amazed, because the Christian I dealt with these past 50 days was extremely different from what other reviewers describe. My opinion is Christian is very high strung and explosive these days. It is for this reason that I write this review. While on my property for a sliding and window installation, Christian had three self instigated yelling episodes, once even to another contracting service. Christian, you see, had a 10 million dollar home to side after mine and said he was behind on my job due to the window delay. The window issue caused a one day delay. Health issues in one of his employees caused a 10 day delay. Holidays (Thanksgiving, Christmas and New Years) caused a 6 day delay. I ended up placing a change order request to eliminate Christian's company from trimming the interior to my windows because I became afraid that Christian would have another explosive interaction. Christian also seemed quite unable to manage his moneys for my job, twice asking for money days ahead of completion of scheduled work. He also used my contract to order materials for another job. Thankfully, I was able to get a lin release, but it was only given to me AFTER removing the material from my property and while job was still less than 50% completed. Some of the material he took away that day was needed to complete my corner railing, so a makeshift corner was placed that is chipped and needs fixed. Even though he was contracted to caulk siding and nail holes, Christian told me his workers aren't as good at that aspect of the job, that I would be better off getting a painter to do that work. I had no problem with doing that until Christian refused to credit me for the cost of caulking that was shifted to a painter. Instead Christian continues to insist that I pay him for the caulking job his team did not complete. Christian has gone as far as to state in writing that both caulking and flashing are not required when installing Hardie siding. He also said that he isn't responsible for insulating windows, just for plumbing them in the jambs. Hardie manufacturer, Azek manufacturer, window installers and an independent 3rd party inspector all tell me Christian is wrong. Pretty certain that the CA Licensing Board will also tell me Christian he is wrong. Christian left my job unfinished. I have 32 feet of missing trim in the front of my house, damaged trim at the water table and on the front corner of my railing. I have 3 windows only partially installed/shims sticking out 4 inches into my room. Christian also removed waterproofing from around my basement door and opened up the door jamb above the door in order to re-trim it, but never finished that project either. He was suppose to come back to complete the loose ends 2 Fridays ago, but never showed up. Instead, that weekend he sent me the final installation invoice, which included paying for all these loose ends, even though they were never completed. Christian insists he is correct in his billing practices and that I am misinformed. I am turning the issues over to the CA Licensing Board for their help as Christian has not followed through to finish the contracted project. He has forced me to get others to finish a job he was suppose to complete. I am extremely worried about this contractor. Christian keeps demanding money for work not completed. Sadly, Christian has breeched my contract. The work that was completed is pretty. When Christian wasn't on site, all went smoothly and hiccups were addressed and resolved. When Christian showed up (thankfully only a few days during the entire job) everything became difficult with excuses for the hiccups, no fixes to resolve the hiccups. I give 2.5 stars to this establishment overall, 5 stars for Christian's employees (Hahns and Bart), sadly 0 stars for owner Christian.

He really knows his business, explained everything, gave some good advice. The cost was about what I expected from an established company. The crew was seven experienced, skilled, and hard-working guys: Jay, George, Rory, Scott, Chip, Ramon, and Jose - all of them friendly and professional. We went for a laced texture that takes extra skill to apply. All detailing around new ANDERSON windows is excellent. From prep to final clean up they knocked themselves out and the result is a house that looks like a million bucks.

Explained what we should do and gave us enough time to look at color samples and textures. We were also given a list of jobs they have done in and around the area, which we went to look at. The date was set, and his crew came out and took care of everything and the house looks great! We've gotten a lot of compliments from people around the neighborhood, in other words, "It's about time!" LOLLLL! And yes, it was time to give the house a lot of TLC since it takes care of us! This is a great company to work with! Thank you all so much!

The Casas team was on time and got straight to work removing the old roof on day one. The next day their delivery of materials was lifted by crane onto or home and a portable restroom arrived too. On time early again the next day and the team spent the entire day installing and making any repairs. They brought their beautiful green hauler to remove trash from their cleanup. Thanks Angel for constantly keeping in touch with updates and pictures. As a member of the Yelp family, I have found honest feedback from others' experiences. Good and bad. And the reviews others post influence my decision. And Yelper's are always right. And so I'd like to recommend Casas Roof to the Yelp community. Their service, workmanship and communication earns them a top spot on my list. Update: 12-31-2025- The owner Carlos called and was very kind to apologize for some miscommunication. He quickly came out and re-accessed the situation and in the evening sent me an email proposal. Now just waiting for the manager to reply to our job request so we can start work. I will update my review again as we move forward. Update: 202601.08 Our manger gave us the green light and we signed a contract with Casas roofing. Carlos has reached out to me asking which color shingles and drip edge. The work is scheduled to start 1/13/26 and we're excited to get our new roof. I will update my review again Yelper's 12-30-2025- This review is only informational for yelpers who find themselves in my situation. Initially, the response from Casas Roofing was great. Replied right away and came to surgery my home. Robert got up on the roof and we spoke afterwards. He said he'd send me an email that Sunday night. Everything seemed fine. When I didn't hear from him I text him. Today Tuesday he called me and said he couldn't do the job due to "liability reasons". An addition to my mobile home which is built just like a regular home was a problem, he said. I know where I live several home enclosed their patio making it into an a proper addition. So I'm not sure what the liability is. So, just a heads up yelpers, if you have a similar situation as mine.

The owner is very responsive and always answered my questions quickly. We got several estimates before deciding who to hire, and Casas had very fair pricing. I would definitely recommend them to anyone looking for roof repair or replacement.
