"So I live in a older house (1947) so the plumbing is older too. Anytime I used my sink dishwasher or laundry the water would all but flood my basement making it almost unusable. I called and talked to Seth he was able to get to my home the next day and diagnose the problem my pipes in the concrete were old and clogged beyond repair well he managed to completely redo all of my plumbing brand new and have it up and running in a matter of a few hours! I now have a dry usable basement. He gave me a very decent price as well! Now hopefully I don't need another plumber anytime soon but if I do I'm calling seth at SWB!"

"Nate communicated with me quickly when I posted my job to fix an outdoor spigot and replace a toilet. He had availability right away, but it turned out that I didn't need him for several weeks. He was able to do the job when I needed him at a very fair price, managed the job well & left things cleaner than he found them. His business is fairly new, but he is a Master Plumber with a lot of professional experience and a very nice guy. We all need a dependable plumber on call, and I've found mine. Hope you'll give him a call on your next job!"

"I have an old farm house. It is at Least 200 years old. It has a stone foundation. Every spring my cellar fills with water. I was given a quote in November on 2022. They installed the water proofing that December. They kept to quoted price with no surprises The crew kept to the schedule I was given. They were professional and left my cellar looking better than I have ever seen it With the soft winter and dry spring I was afraid that their work would not get a good test. However, last night We got four to five inches of rain. In the past this would at least left a foot of water in my cellar. Today it is bone dry. Basement Improvement is a local family run business that I would highly recommend to anyone."

Basement Waterproofing FAQs, answered by experts

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

Yes, cleaning a crawl space is worth the cost. Although it's an out-of-sight area, neglecting it can lead to significant problems like pest infestations (including termites and carpenter ants), mold, and fungal growth, which can cause structural damage. Regular cleaning helps prevent these issues. While hiring a contractor has ongoing costs, the price for cleaning—typically between $0.50 and $4 per square foot—is much lower than the cost to remediate a pest or mold problem. Additionally, a clean crawl space can lead to improved indoor air quality and more comfortable temperatures in your home.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

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.
