Sealing concrete and wood structures comes easy for us at PermaSeal. Contact us today in Chesterfield, MO, so we can get your project started.

"I had my driveway sealed with Permaseal in 2020. I thought I understood sealing with this product would eliminate the annual sealing that my concrete contractor recommended. Their info online says it saves annual sealing. Well, surprise! When in late 2021 and 2022 I began to see spots on the surface where the concrete seemed to be coming off or pocked marks I contacted Permaseal. They inspected it and the owner of the company says their product goes deep into the concrete but does nothing for the surface. That limitation is sure not what I expected. I say buyer beware. If you think you're getting your surface sealed then you are not. I think could have saved a lot of money and paid to have my drive surface sealed annually."

Basement Waterproofing questions, answered by experts

Mold can grow anywhere in your home where there’s moisture that doesn’t dry out, usually in areas that are either not ventilated properly or where moisture gathers continuously. Insulation, drywall, and foundations typically provide mold with areas to grow if moisture is present and does not have a chance to dry out. Some of the most common areas in a home for mold growth include:

  • Attic

  • Walls

  • Bathroom

  • Crawlspace

  • Basement

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.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

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, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.
