"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

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.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Water damage to a foundation often starts as a slow leak or water vapor problem that worsens over the course of months or even years. The speed at which foundation leaks worsen depends on a few factors, including your climate and location, the soil composition around your home, the foundation drainage system you have in place, if any, and the type of foundation you have. Even if you have a minor issue that’s slow to develop, it’s best to have a professional address the issue immediately.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
