"We’ve had a lot of crews in our home for various projects over the years, and I have to say this was one of the most courteous. They worked hard, navigating through our kitchen to access the basement and I really appreciated their efforts. Thank you MTU, we now have safe walls in our cellar and fresh beams to keep the house standing ;)"

"They were professional, polite and careful to be considerate of the home. The job was an unexpected need to upgrade an electrical circuit to accommodate a hot water tank replacement. While I was not thrilled about the unplanned expense, I was very happy with the process with Seatown EH&A"

"The workers were hard working. Did a great job. The only concern we had was the lack of attention to the workers: no porta potty and no machinery to help carry the heavy concrete. Still waiting for the $250 gift card reward, lol!"

"The Seatown team did a great job. I got quotes from 3 different recommended plumbing services, but the Seatown guys were the only ones who recognized we would need to upgrade our gas meter. They did a great job explaining how to get this scheduled with PSE. The estimate Seatown gave was on par with some of the other plumbers, so we went with them. They sent 2 service people to come and install the tankless and the guys were just excellent. I expressed concern about mounting the water heater on the beams in our basement because Our house is so old, so they came up with a better solution. They built a small wall frame to mount the water heater. No extra cost. When they found there was no outlet wired near the heater they were able to get an electrician from Seatown to come out and wire one up while they worked on the water heater install. Seatown aldo had a good scheduling method, sent text reminders the day they were coming to do the work with a photo of the person who was coming and a short set of info about the person. It was a nice touch, and a thoughtful safety measure. They did a great job with the install which took several hours. I’d definitely hire them again."

Basement Waterproofing FAQs, answered by experts

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.

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.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
