"Our basement got flooded in early January 2023 during a bad storm. We got estimates from 2 waterproofing companies. CGS Waterproofing sent a representative quickly to survey the damage and let us know what needed to be done. Nick seemed to be very knowledgeable and experienced in this type of work. An estimate from another company was considerably higher. After getting the 2nd estimate, we called the CGS rep. again (Nick) and asked him to clarify some things in his estimate. He came back out for a 2nd visit, and declined to take any compensation for the additional trip. The men who came to do the actual work were fast and efficient, did exactly what they said they would do, at the agreed-upon price, and they left no mess. We could not even tell that portions of our yard had been dug up, because they made it look like it had not been disturbed. Since then we have had several rain events and no water has even come close to our basement. I highly recommend this company."

"I was impressed from the time Jose visited my home, understood what needed to be done and prepared a complete estimate. This was a tricky and labor intense job. Few people wanted to take it on and I was very worried if we would ever find a way to get the work done the way it should be. The cost was fair and successfully completed, as scheduled. I am thankful I found them, called and worked with them. They exceeded our expectations! Thank you Jose and Georgia Waterproofing and Tree Service!"

"⭐⭐⭐⭐⭐ 5 Stars Review for Vasquez Waterproofing Vasquez Waterproofing did an outstanding job installing a French drain in both my front and back yards, and they also tackled some pretty extensive water damage around my front bay window. Not only was the quality of work excellent, but the entire project was completed in just two days — super efficient. Big shoutout to Jack for his excellent communication throughout the process. Everything was explained clearly, timelines were kept, and the worksite was left clean. I’d absolutely recommend Vasquez Waterproofing for any drainage or water damage projects. In fact, I’m already in talks with them about another job. Solid team, great results."

"From reaching out to Angiâ s List regarding my basement flooding, to receiving four credible businesses for me to pick from, to selecting Aquaguard. The entire process was transparent (walk through, analysis, quote, to the actual crew. I recommend Aquaguard to anyone experiencing a leak or just want to proof your home before you complete your basement. This is your one stop shop!!!"

Basement Waterproofing FAQs, answered by experts

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.
