"Having to go through water problems in a basement is stressful but I am so glad I went with this company. Every person I interacted with was competent and professional. Larry was my first point of contact and he was incredibly knowledgeable and contacted me regularly to check in. I had scheduled multiple quotes but Larry sold me instantly because of his knowledgeable and straightforward communication. Todd, the owner, was so kind and you can tell how thorough he is about the work he does. He took the time to explain things to me and even catch things outside their job scope to make me aware of. He was incredibly fair with the pricing of the job. Nick and Dave were the two I interacted with the most because they did a majority of the labor. They were the best. They were respectful and knowledgeable. They took a lot of time to keep me updated and offer guidance for the long term care of my home. Having them working in my home never felt inconvenient. I could not have been more pleased with them or their work. I would highly recommend this company and the team they have assembled. Thank you for saving my home!"

"It was a complex project. They were very careful with their procedures and raised sunken concrete sections next to the house and around a pool to allow for drainage. They filled the major cracks.

"DO NOT hire Dan Ford aka Dan the Handyman. I hired him to install a stone walkway and it is a complete disaster. The workmanship is terrible. The walkway is falling apart, breaking and lifting and is a trip hazard. I had to take him to court to get my payment refunded. I was awarded the judgment, but Dan Ford has NOT paid. I ended up having to file a transcript of judgment with the County Court and have a lien placed on him and his business. He still has NOT paid. Do NOT hire Dan Ford aka Dan the Handyman."

Basement Waterproofing questions, answered by experts

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.

Generally, moisture barrier padding costs $0.75 to $1.50 per square foot, varying by brand and mix. That’s a lot more than standard padding, which runs $0.25 to $0.90 per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.
