"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!"

"Guys came in and worked. No lollygagging or long breaks or any of that just plowed through on a dirty two-day job and their work made me feel a heck of a lot better about the structure of our home. Did great work. The only complaint is that they did not repair a small basement window casing that they pried open to get materials to the basement. I am sure had I contacted them they would have come back and fixed it, but it was not anything nice to begin with and I was able to repair myself pretty easily so I never even brought it to their attention."

"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

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.
