    CGS has been our goto construction company for many years now. Most recently they did a great job constructing a fence around a basketball court we paved. We look forward to using them on our next project.

    New roof done by CNG waterproofing.
    Wendell L.

    We needed a new roof after 17 years. So I looked and compared roofing companies. I read reviews of 7 different companies, and then I read CGS waterproofing reviews, and I was satisfied with what I read. I wanted a reliable, honest, and professional experience. That's what I got from CGS. First, I want to say thank you to Carlos Martinez for getting his works out here on time and doing a fantastic (one day) job. They arrived at 7am, by 7:30am they was stripping the roof. Clean up their mess, and it was all done in one day. I have told my friends family about CGS and how wonderful of job they did. I recommend CGS waterproofing.

    I noticed some moisture forming on the walls of my basement/crawl. I was concerned because of the humid smell coming from the basement so I called CGS to see if they could diagnose the problem. From the office ladies to the inspector jay to the crew that came out it was seamless! They have very reasonable pricing and it's affordable (in comparison to aquaguard and other companies) I was able to have to work done within two weeks of initial inspection. I will be recommending CGS to my friends and family!

    I have been having leaking problems for days and with these rains it has gotten worse so I decided to look for a waterproofing service to solve my problem. Searching on Google I came across CGS waterproofing which were at my service from the beginning. They had an immediate response and they explained to me what has to be done. The price they gave me seemed very affordable and fair and the service was always top-notch, They were on time and finished in a couple of hours. I'm really satisfied with Joaquin and his entire crew, I like being able to rely in professionals. A few days have passed and the quality of service remains intact. 100% recommended.

    I had water coming in for the longest time in our new home. The home inspector did not notice the water when we purchased the home and we were stock with the problem. We called many companies but after 4 estimates we decided to go with CGS. They had the best price way lower than the other estimates, which made us doubt their quality. We got our waterproofing done 4 months ago and no water since. We recommended them to 2 other friends and they loved it. Not always low prices mean low quality, at least not with them! Do your self a favor and get an estimate from these guys if you have water intrusion. Thank you CGS

    It is now years later. And I realize the drain was clogged because they never removed the knockout separator between two pipes. Horrible job

    This company is horrible. Do not give them your money. Do not let them touch your house. All those…read moregreat 5-star reviews from several years ago were under the company's previous owner. The current owner, Brian, doesn't care if his company's repair job is done correctly or fixes the issue they were paid to fix. We hired Foundation Worx to add support under a hallway in our home. The job was done incorrectly, creating a large bulge in our bedroom floor and causing substantial drywall damage. I emailed Brian immediately and received no response. After calling the company a couple times, they finally sent out a salesman who doubled down on the improper repair and claimed there was no need to make any adjustments or corrections. We hired a structural engineer who confirmed the job didn't resolve our hallway issue and actually made it worse. We sent a Right To Repair letter certified mail to Brian, which he was supposed to respond to within 30 days. Brian did not respond. After waiting over seven weeks for a response that never came, I emailed Brian again and asked for a refund, as our house experienced significant further damage while we were jumping through these hoops trying to get a resolution from Foundation Worx. Brian finally responded but only offered to repair their project, 6+ months after they broke our house. This repair should have been offered to us immediately. As we could not trust Foundation Worx to repair our home properly or in a timely manner, we paid another company to do it. I requested a refund from Brian multiple times and this request was ignored. Save yourself the nightmare we went through and hire another company.

    This is my first yelp review ever and I'm doing so because apparently this company or at least the…read morewoman who answers the phone, says they don't do what their business says they do! I have a leak of some kind in the lowest level of my townhouse. A room I rarely used except to store things I have figured out what to do with. Sometime last summer with all the hard rains I ended up with a leak in the back corner. I didn't know about it for months but my HOA, who won't touch anything foundation, did send someone out and with some basic testing found a spot on the outside which correlates to where the water comes inside. Since I didn't discover the problem for months there is some mold on the baseboards and edges of the carpet. I called Foundation Worx to get an estimate and explained the issue. The woman who answered the phone first told me that they couldn't do anything until the mold was taken care of! REALLY! I questioned that since if repairs are done inside before the foundation repairs are done and then we get heavy rain, I end up with new inside damage to be repaired. I repeated that I wasn't asking them to repair the inside, I wanted an estimate on fixing wherever the leak is on the outside. That's when she told me that because my townhouse was on a slab they couldn't do the repair because they would have to dig down. I'm not foundation expert but I don't see how it's possible to fix any foundation issue without digging down to see/fix that area of the foundation! Looking at other reviews where people paid deposits upfront and their people never showed - I'm glad they refused me. Stay away from this group!

The one this company installed in 2023 quit working in 2024 after the one year warranty expired and I had to pay $1,000 to have another one installed. March 2025 the dehumidifier quit again. I called and they sent a technician out here and he said the company no longer uses those dehumidifiers. He inferred that they are of substandard quality and if I purchased another it would be quite expensive. He checked the dehumidifier and said my electrical outlet had switched it off. So, I paid an electrician to replace the outlet with one that doesn't automatically switch off. The dehumidifier continued to quit working. So, I asked an HVAC company to come and check it out. He said the dehumidifier is fills with water and cuts off because it isn't draining properly. He emptied it out and said it hadn't been correctly installed. He said it needed a condensation pump and the tubing needed to be replaced. I tried to reach someone at Crawlspaces and More and for weeks never received a return call. I finally received an email from Jim and he said he would come out and make sure the dehumidifier was on and charge me $200. I told them to forget it. I called a reputable company and they installed a very nice dehumidifier and replaced the door to my crawlspace. Ours was wood and rotted because it was decades old. They said Crawlspaces and More should have replaced it to thoroughly encapsulate the crawlspace. The new company installed a custom fit door that is air tight and sealed. I would not recommend Crawlspaces and More.
