"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

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.
