We were thrilled with GAXL! They built a 12x14 exercise studio from scratch. They worked hard and got it done quickly. Excellent price. Friendly team. Good communicators. The work quality was good and just what we needed for this structure

We had a wall and door installed to create a closet, plus electrical for the closet. The team was fantastic and very thorough. We liked the so much that we asked them to come back for several other projects- replacing a doorframe, a garbage disposal, and installing a water heater and faucet. Great work and super professional. We will absolutely use them again!

Excellent experience with GAXL. We had sagging rafters in our attic that needed to be repaired. It was an extensive job, as each rafter individually needed to be jacked up and reinforced. Mr. Galicia did thorough evaluation and gave me a clear explanation and bid. He worked with me to find best date to begin the week-long project. His crew was polite, professional, and very hard-working. At all points in the project they communicated with me about progress and took great care to keep the rest of house clean as they carried big two by fours in and carted debris out. Project was completed ahead of schedule and looks great. I highly recommend GAXL to anybody thinking of doing similar work.

I recently hired Luis and his team from GAXL to create an attic entry in my home, and I couldn’t be happier with the experience. From the very beginning, their professionalism stood out. Communication was excellent throughout the quoting process—Luis was responsive, clear, and made sure I understood every step.
The team arrived right on time and completed the job exactly as scheduled. I was especially impressed with how clean they kept the work area; they treated my home with care and respect. The quality of their work exceeded my expectations, and the whole process was smooth and stress-free.
If you are looking for a reliable and skilled general contractor, I highly recommend Luis and his team. Great service, great results, and a great company to work with
