"Skyler and TerraFirma far exceeded our expectations. The injection process of the foam raised our cracked garage floor back to level. Skyler’s customer service was the best. I highly recommend TerraFirma and hope that you get Skyler as the person doing the work… you will not be disappointed!"

I am a self-taught artist, initially drawn to experiment with pastels and colored pencil, and now working with acrylic on canvas. My art speaks for itself.

Basement Waterproofing questions, answered by experts

It’s not safe to live in a house with water damage until a trained professional gives you the all-clear to return. Mold can grow within one to two days after water damage and weaken your home’s structural integrity. Always have your home inspected after water damage to ensure it’s safe to live in.

Depending on the severity, a slab leak can go undetected for months or even years, especially if you don’t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

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.

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.
