Cobex Construction

Cobex did a great job replacing my old roof from the initial call to final cleanup. They were very responsive in getting all of the details right Ahead of time, and were prepared for every question.

I regret hiring Cobex to install a new roof on my house. They took five months to begin work and took twice as long as expected to complete. We asked the sales crew for custom skylights and to repair dry rot on the architectural details of the house. None of these details were passed to the construction crew and during construction, we were told the custom skylights would not be covered under warranty. It also became apparent that they did not have the expertise to handle the carpentry work for the dry rot repair. I had to manage the project daily to direct the repair work and point out corrections. In the end, we didn't get the skylights we agreed to and the dry rot repair and detail work was subpar. They missed areas of dry rot and used inferior wood. Also, Cobex did not tarp the roof before a predicted rain storm and damage was done to the interior ceiling, walls, furniture and carpet. Five other homes they were working on were also affected. I hired another contractor and did work myself to make repairs they missed since I did not trust Cobex's workmanship. We were given a discount but that did not cover the cost of additional repairs and rainwater damage.

Wow! I can't thank David Leal enough for helping me get a new roof and some windows. The guys he had working here were the best. Cobex and David have restored my faith in the construction industry. Thank you!

Good work and customer service.

Well, my review if preliminary because we are waiting for permits and for the rain to stop but up to this point everyone has been very friendly and professional! Trying to keep me up to date on everything. I will update this as we proceed!

They did an amazing and awesome service. They were communicative, timely, responsive and did the job quickly. They were great and very professional.

Very very positive I'm very very happy with them.

This company hires sub-contractors for their work and the quality of their work is poor. The gutter screens weren't installed correctly by the sub-contractors so they had to take everything off and re-attach them. Gutter connector broke so rain water was running off the side of the house so they came out to fix that. I would never hire this company for any work anymore.

skillful, professional, excellent followup

Good workmanship and good responses to job details that was missed. Need one single person contact throughout, we had to work with three. Need more careful and thorough inspection of completing the entire job. Best by one single person overseeing the entire project. Some disconnect between the saleperson and the project managers. Problem: The power and phone lines were not reinstalled and left hanging over the shrubs. Your strength is your workers they were very skillful and responsive and left the place.

I am still using them and they're doing a great job here. I have referred them to a friend and they're gonna be using them.

I was very impressed with my mother's roofing job - she has a Streng home - very snazzy architectural design but they have roofs with very little angle so they won't take shingles - they used a roof liner (like commercial properties with flat roofs use) and I was very impressed with their work. Because of their work on my mother's roof I hired them to replace my gutters (I had one area where there was a little waterfall every time it rained hard). They were not inexpensive but they did excellent work and used high quality materials so I think it was worth it. I would recommend them to anyone looking for work on their house.

The repair went so smooth. The men who did the repair in the front of my house were so professional and wasted no time in getting the job done. They have so many people who are so knowledgeable in all facets of home repair you get a top notch group who know what needs to be done and how to do it. The roofers were also fast and efficient. The painters make sure they have covered all spots with the exact same color you had in the beginning. They have an "eagle eye" who comes by and rechecks everything to make certain you are happy with their work. I was!

I love it! it looks beautiful

COBEX CONSTRUCTION GROUP, exceeded our expectations. So professional and excellent quality work. I would recommend them to anyone looking for top quality work at a great price.

Perfect. Excellent craftsmanship.

We are so happy we chose Cobex to do our remodel. We saw the recommendation for them on NextDoor and excellent reviews on Yelp, and they are living up to their glowing recommendations. Dimitri and Dave pay close attention to details and let nothing fall between the cracks. Their workers are a testament to the quality they provide their customers...they all work so hard and through it all are friendly yet professional.

I am very happy with the work done by Cobex and would definitely use them again, as well as refer others to them. They built me a 12' x 45' redwood deck that was permitted and inspected. They also poured concrete for a patio, walkway and custom stepping stones. I dealt with Dmitry and he and his crew were exceptional. On time every morning, clean up of the work site every night, and true craftsmen who took pride in their workmanship and genuinely cared about pleasing the customer. That kind of service and craftsmanship is hard to find these days. The Cobex crew was top notch!

We needed new windows that were more energy efficient. We had Cobex come in and install new windows throughout our house. We also had our duct work redone and new duct work installed in our attic. Now our home is actually warm during the winter and our heater doesn't need to be blasted anymore! The windows look great and we had no problems with our strict HOA approving anything. Thank you so much Cobex for taking care of everything for us.

Cobex offered great value for my money. Their price was around the same as other quotes, but they used better materials. In addition, Vaz patiently answered all my questions and gave me prons and cons of the different upgrade options. We ended up also using Cobex for attic insulation and gutter guards. The true sign of professionalism is how a company reacts when issues come up. We had a couple of minor issues from the construction that Cobex addressed quickly. I also like how they handle everything electronically. No more printing, singing, scanning, and emailing documents back. We've had lots of compliments on our roof. We would totally use them again.

Quick and high quality. They kept me informed throughout the process. The price was very good!

They were fantastic to work with. Very professional, neat and clean, on time, and hard workers. True craftsmen who took pride in their work and really wanted the customer to be happy. I would definitely use them again! I love my new deck! Price was what I expected to have to pay.
