"I found them on Angie’s List. He showed me pictures of everything and what he took out. He showed me the work and it wasn’t like made up or anything. He took pictures before and after on the roof of the part that was rotten and after he redid it. I was happy with him. I looked afterwards and there was no complaint. They did it in a timely manner, like they said they would. There were rain delays and it wasn’t their problem. They never tried to change the price on me. They cleaned up like nails and stuff in the driveway. I checked the driveway and there weren’t any nails or anything. They did a pretty good job. They did fine and it was a good job. I did have other estimates and they were okay. They called and asked if anything was wrong, and it has been a year. They got delayed and the work got a little hurried but it was damp and they couldn’t get to it. They did everything they were going to do. They didn’t try to cover and not replace certain things to make more profit, and I see all new gutters and everything."

Basement Waterproofing FAQs, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

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.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.

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.
