"Greydon and his team made this project I was dreading seamlessly easy and ALSO affordable. I was provided 3 other quotes ranging from $8,000-$15,000. He was straight forward with me and kept me updated in all aspects. I’d gladly pay $5,000 for a sewer repair to work with a honest, dependable and all around amazing company!"

"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

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. 

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

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

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.
