"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

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.
