Javier and his crew are best in class. Javier was patient and accommodating throughout the whole renovation process. My wife and I renovated our basement which included a full bathroom addition, removed a bilco door and replaced it with a rear entrance, and renovated an enclosed porch to an open concept porch. At one point, Javier had recommended I consider replacing my sewer line but never pressured me to do so. After careful consideration we made the decision to replace the sewer line and we’re glad we took his recommendation into consideration as it was in need of replacement. Javier and his crew maintained professionalism, always ensured the worksite was safe and clean, and proactively checked in to see if I had any questions. Overall, my wife are extremely grateful and we plan to use Javier in the future and certainly plan to recommend him to our friends and family.

This is the third time I am using GMATT builders for renovation, and this is the largest and most extensive renovation I have done to date. I am extremely happy with the work that I have received on all three of my renovations with GMATT builders. The first renovation that I had with GMAT builder was at my previous house, it was a roof replacement. The second renovation that I had with him was the installation of a very large picture window at my first house. Both jobs were done within the time frame that Mr Gomez had advised, and they were done very well.For my most recent renovation, which was the extension of the back of the house, with an addition of approximately 350 ft, plus a new kitchen, plus a new laundry room, shower, and a new pressure treated deck that is approximately 360 ft. After getting bids from multiple contractors, I once again contacted Mr Gomez for a bid. His bid was competitive with the range that had been proposed to me, and having worked with him over a time frame of 20 years gave me the confidence to go ahead with him on this job, the largest job to date.His work is excellent. The building of a crawl space, new exterior walls, roof, finished walls and floor, installation of porcelain tile floors, installation of the shower, installation of a skylight as well as several windows and two doors, the installation of my cabinetry, including the crown molding on the cabinetry, installation of the lighting, and last but not least of all the installation of a 4,000 lb steel beam to hold up the entire second floor of my house have all been done very nicely. Mr Gomez is on the site almost every single day, And he does much of the work himself, along with his employees. I find that he brings the same employees time and again, so I feel confident in knowing that he has trained and supervised them well, and is not the type of contractor who has a part-time crew working for him intermittently, which is one of those things that we are told to watch out for. I felt very confident leaving him at the home to do the work while I went to work myself, knowing that the work would be done properly.Mr Gomez is receptive to my inquiries, and answers all of my questions very patiently. He addressed all of my concerns. I have been very happy with the overall work. I did have some issues with my heat, some heat loss, some issues with the tile work and the trim work that were noticed after the completion of the job, and he has been very attentive to taking care of all of those needs.If ever I need to have another small or a large renovation done, I would not hesitate to contact Mr Gomez again. I have been using him for several smaller jobs over the last 20 years as well, not including these three larger jobs, and have always had a positive experience with him.Feel free to contact me if you have any questions. Please take a look at my finished kitchen.Thank you Javier! You rock!

I am so grateful for the work that Gmatt Builder completed at my home. Javier and his crew worked really hard and were very patient and understanding. He provided me with very detailed specifics and spreadsheets that outlined the project costs and he took the time to explain the process. When challenges came up(as they always do with construction) he was sensitive and understanding.
