"Wow. I have used Classic for 8 years, both for insulation and pest control. They were great to work with and did a consistently good job for a reasonable fee. As a text from them today requested, I called to reschedule a service call. The person who answered identified himself as the owner, and indicated he was “back” because he didn’t like the way the company was being run. Because I wanted my service to include a crawlspace inspection of the rodent traps that they put in - something that is part of the service they have always done — and that I pay for — said I was being too rigid and he didn’t want me as a customer. Again, wow."

Basement Waterproofing questions, answered by experts

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation.
