"We contacted them for an estimate on our basement.  Initial phone call and connection went well, very professional, quick, and prompt.  Once the rep was at our home he went into a "pitch" vs. listening to what we said we already knew we wanted.  We even had a sketch.  Eventually we went to review the space, take measurements, etc.  We then started to pick out materials......he brought all the samples but then put together an evaluation based on square foot and overall price of our home and used that based on the square footage of our basement to determine a "fair" value........which was $100/sq ft.  That would have equated to over $100,000 basement.  Then he said how much "fairer" their price was at the quoted rate.  We were too far apart in our estimates which is fine with me, but at the end he said if I obtained a quote that was lower ~ to give him a call and they'd see what they can do.  At that point, I believe "no thanks".  Give me your best price up front.  The entire visit took almost 3 hours.  It was a big waste of time for all unfortunately as we had no intent to spend that much.

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.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.

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.
