"I contacted Fausto from Tigasi Insulation to discuss a project in my basement. He arrived on time, and from the beginning, I could tell that he was a professional who takes pride in his work. At the end of the job, Fausto personally asked me to inspect the work that had been completed. I was very impressed with the quality of his work and the excellent job he did. I highly recommend Fausto and Tigasi Insulation to anyone looking for professional and reliable service. Thank you, Fausto, for the great work!"

"When it rained my basement would get 2-3 inches of water. Tim and his team redirected all of the drain pipes (5 in all), reshaped the slope of the land surrounding my house, planted grass seed, and left the yard spotless. Now my basement is drier than Arizona in mid-July. These guys are pros, they finished in a day. It was a pleasure to see these men work! Their price was more than fair. You can't go wrong with DIGGS! Thank you, Tim!"

"Headly was very knowledgeable and professional. He was also very honest to tell me that the issue was not an emergency as I thought it was. He gave me a lot of information about the water in our basement and advised me to call him if it happens again after a heavy rain. He also checked out and cleaned my gutter while he was there."

"Excellent basement waterproofing service! The team was professional, knowledgeable, and worked extremely hard from start to finish. They explained everything clearly, repaired the problem areas, waterproofed the basement properly, and left everything clean when the job was completed. The difference has been amazing ? our basement is now dry and protected, even after heavy rain. Great workmanship, reliable service, and very fair pricing. I would highly recommend them to anyone needing basement waterproofing or foundation repair."

Basement Waterproofing FAQs, answered by experts

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.
