Construction Company reviews in Castro Valley, California

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

Working with GAXL was great.
I would recommend them for your future project without any hesitation.

We were moving to a new location, project included to the do the flooring ( remove the existing tile to do carpet ), painting walls, a bit of plumbing work, adding a door to storage room and attain ADA compliant bathroom.

Jose owner of the company was great to work with along with his crew. He was able to pull the required permits from the city and he was able to address the questions the city officials had to approve the permit.

They were able to complete all of the above said work in a little over 2 weeks as promised.

The cost of the project was reasonable pricing comparing with the other contractors and lower than some of the quotes I got. I gave 4.8 as few of the material costs were higher but that is very small percentage of the whole project.

A minor issue popped up of the work they have done at the bathroom sink which is not related to their job but Jose was able to take care of that without any additional charge.

We were in need of a deck replacement and the team at GAXL was very helpful! Very responsive and professional.

GAXL Construction & Plumbing recently replaced our patio with beautiful concrete pavers, and the entire experience was outstanding. From start to finish, they were professional, communicative, and committed to delivering top-quality work.

Their craftsmanship is superb—every detail was done with care, and the finished patio exceeded our expectations. The crew worked incredibly hard each day, often staying well into the evening to keep the project on schedule. Despite the long hours, they remained positive, focused, and respectful of our property.

They completed the job on time and on budget, with no surprises—just excellent service and exceptional results. I highly recommend GAXL Construction & Plumbing for anyone looking for reliable professionals who truly take pride in their work.
