I needed to convert an old closet into a professional voiceover booth. Tony was super easy to work with, and took all of my considerations into account. The booth was built with ""decoupled"" walls, filled with acoustic insulation and finished out with a heavy acoustic door. The end result is a fantastic booth, exactly what I was looking for.

Hats off to Tony and his crew for doing a FANTASTIC job!

This is the second project Tony, his son Mark, and the rest of his crew have done for us and it won't be the last. For this project, we wanted new cabinet faces and a paint job for our kitchen, and a tub to shower conversion for our master bath. Both jobs turned out beautiful and were completed on time. There were a few hiccups along the way, but what remodeling project doesn't have some. With that being said, Tony handled them professionally and we figured them out. A real standout was Regal, who did an amazing job with the tile in the shower. He has really clean lines and an eye for detail. He made the shower look exactly how we envisioned it and now it's like a five star hotel. Mark, Tony's son, is a great successor to the GIS brand, and couldn't be a nicer guy. Every day of the project, he was great at communicating and making us feel at ease. Check out the pictures and the results speak for themselves.

I would highly recommend Tony to anybody. He is honest, fair and professional.

At first I couldn't afford Tony's bid. But after talking to him about it and splitting up the work and materials we came up with a mutually agreeable contract. He was really easy to talk to and that helps immensely.

I really liked that he showed up in a mask and it took a little longer than expected because of Covid.

Not only was Tony easy to communicate and work with, his crew did an outstanding job. And when he asked me about how I thought it was going, I pointed out a few minor issues that he addressed immediately. He had all of his guys there within the hour to alleviate any and all concerns. He really listened!

If I could give 6 stars I would. Tony and his team were amazing. I hired GIS to convert a sunken bonus room into a self-contained studio apartment with a full-size bathroom and kitchenette. I received many quotes and GIS was really competitive. The plumbing work was quite extensive but Tony's team was very knowledgeable and professional in keeping informed every step of the way. The most impressive part, they pretty much created a masterpiece from just my imagination. It's beautiful and exceeded my expectations (which isn't easy to do). I have several other projects that I need to do and I will most definitely be working with these guys again. I actually enjoyed having them at my place every day which was important for me in working with any contractor. Great energy, a bit of laughter and great work. Can't beat that!!

I'm a home owner with very little skill or time in maintaining a home. Tony provided the skill and patience with me in upgrading my home the way I wanted it. I would highly recommend G.I.S Contracting to anyone needing home repairs or upgrades. They repaired my roof, removed carpeting and installed laminate flooring, painted, installed fencing (removed the old one), and installed a French drain in my back yard which alleviated standing water.
Thank you G.I.S for all your hard work!!!

GIS Contracting did extensive remodeling work on our home in late 2017. There were some red flags early on, but things seemed to be going well enough and we had already paid the deposit up front so that we continued with the project anyways. Unfortunately, things only got worse.
Their work ended when we confronted them with a list of things that needed to be fixed or finished and they refused to come back out, saying that with the remaining amount we owed them (less than $1,000) we could get someone else to finish. We made several attempts to talk to them to reach a resolution until the company owner, Tony Gomez, stopped responding. We finally were able to hire an attorney to try to recover some of our losses.
After a long and drawn-out legal process, we have come away with nothing. Mr. Gomez' settlement offer was for them to come out and repair some things (a partial list of the items they did wrong) themselves. We were willing to accept this without them even covering any of our legal fees (which have greatly added up) if they would agree to do the repairs under the supervision and meet the approval of a certified structural engineer that we would hire and pay for (again they did not want to pay for this service so we were willing to pay for it ourselves). They refused to do that, so because we can't afford to continue with legal action we decided it would literally be better to get nothing than to have GIS do any work on our house again. That's how bad their work was. Below is (an abbreviated) list of problems from the work GIS did on our house:

* from the certified structural engineer's written report after evaluation of where GIS added concrete to make our porch all one level and add a portico: ""The porches have no footings and are founded at grade. As a result of the this, the porches have settled and caused damage to the framed structure of the house and to the other, existing portions of the front porch (spalling concrete and cracks in the porch slab). These porches will continue to settle and will not perform as intended. Continued damage to the home may result due to the poor quality of the concrete flatwork. The concrete slab was also poured against bare framing of the north renovated garage area, and the settlement of the slab has caused a gap to exist with an opening into the wall cavity. The area should have been flashed and have solid sheathing below the lap siding. As constructed, the sheathing/concrete interface will allow water to enter the interior of the home.""
* Mortar between stone at front posts began cracking/crumbling away within a week or two of it being done and at least two of the stones are completely detached now.
* a leak in the flashing around the chimney GIS installed was discovered in November 2018 when we went into the attic and saw water pooled up around the chimney in the attic.
The portico soffit was not given any ventilation and because it is an addition that is not connected to the attic space, it has zero ventilation. It is now sagging, which we suspect is due to the lack of ventilation leading to moisture build-up.
* The tile was grouted with a color other than what we had selected. No moisture barrier, membrane, or coating of any kind was used to prevent cracking and tile shifting despite repeated requests and written instructions asking them to do so. A broken tile and areas with cracking grout appeared within a year.
* During construction inside the house the A/C unit inside started leaking, puddling up in the return and draining into the hallway. They were tearing down drywall, breaking up concrete, sanding joint compound, etc.... and never masked off the hallway where the A/C return plenum is. After this, we had problems with the A/C leaking for the next 4-5 months until we had it repaired by someone else. Additional drywall damage in the bathroom resulted from the A/C leaking.
* fireplace surround was not properly secured to the wall and poorly constructed. the mantle was made with a single sheet of pine that was twisted and cupped, and had 6 large knots that were left unfilled.
* Window casing installed with ¼"" gaps, allowing hot/cold air to flow through.
* Some trim was installed so poorly that we told them it was unacceptable and to redo it. They said it was because the walls were so uneven, as though it would be impossible to fix. Some doors were trimmed with pieces of mismatched trim.
* None of the wood knots were sealed on the exterior before they painted the pine so within 6 months all the knots had bled through.
*Part of gutters dismounted; others leak. Downspouts on the back of the house do not aim the water run-off away from the house
*We did not receive, even upon asking, verification that electrical work was done by properly licensed workers

At this point we just hope that by sharing our experience, others won't get screwed over the way we were.

Awesome company and very knowledgeable, skilled workers.
They did a partial remodel of an outdated bathroom. Found many glitches in previous work. Never took action on them until they discussed with me first. They are good on their word and have a great team.
Needed an HVAC on short term notice. They had one out to me that evening and all was taken care of.
They take pride in their work and want you to be happy.
Great customer service!

Tony and his crew were amazing and built me a custom closet storage solution exactly to my specifications. The closet space was super weirdly configured, but he and his guys worked with me to make sure they maximized storage space, gave me a rack to hang my long dresses, and even gave me ADJUSTABLE shoe shelves. From quote to completion of the project, Tony made sure I was happy and was constantly ready to go above and beyond to make sure the closet was perfect. He even gave me tips on what paint to use because I wanted to paint it all myself. 10/10 recommend GIS Contracting for any custom cabinetry, shelving, carpentry, or renovation projects!

Do not used this company! The works look dam good but on the inside of the walls it's a dam mess. They use their friend who is NOT a licensed electrician but someone that installs solar panels with his father. Extremely disappointed in this company. They did not honor their contract and took my money and ran.

As we were installing a new cook top in our kitchen, we discovered that the stone countertop needed to be cut. Tony and G.I.S. came to our rescue, and sent someone out the next morning (which was a Saturday) and did a great job. Other contractors I tried wouldn't even consider the job because it was quick, but Tony responded right away and was great to work with.
