"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 ;)"

"The bud for the job was the most complete, covering all aspects of the job that other companies did not cover. My own past work experience was helpful in understanding that every phase of the job was covered in the bid. On the other hand, the other, lower bids left a lot of items out, which would probably be, a oops you need this/oops you need that situation that would in the end make the other bids end up being a higher cost. The finished job included re land scraping the excavation, seeding of the area and a layer of peat moss to encourage the seeds to grow. A section of sidewalk needed to be cut out, and they did a great job in replacing it with new concrete to my satisfaction. A very complete job I the end."

"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

If you decide to fill the space around your home’s foundation with landscaping materials, it’s important to consider the aesthetic as well as technical factors like drainage and protection from pests and the elements. Materials such as gravel, rubber mulch, concrete, and brick masonry are all good options.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses.
