"Question above did not allow me to specify the nature of the waterproofing that was done. He stopped water from seeping through the floor of the den. Gregg is old school, a man of his word, not primarily out for profit and truly committed to getting the job done even if repeat visits make it not cost effective for him."

"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."

Basement Waterproofing FAQs, answered by experts

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Below-ground shelters are the best in terms of durability, but there is a risk of flooding and obstruction. Modern technology and rigorous construction requirements make above-ground shelters a better option for accessibility, safety, and, usually, your budget. They may not have the same aesthetic appeal, but many of their features make above-ground shelters a better option. 

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.

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.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
