"I am very pleased with the work done by Greentree Waterproofing and would recommend them to anyone. They were very responsive. I called on a Monday morning after having water in our basement since the previous Saturday and within two hours an inspector was at our home to give us an estimate on the work needed. A crew arrived the following Monday and by Wednesday afternoon the work was done. Previous to this work being done, we always had water in our sump pump and it ran almost daily. Since Greentree did their work, we haven't heard the sump run and the pit is dry. Very impressed with the work and would use them again."

"We were pleased with the customer service, skill set and careful attention provided by Indiana Foundation during last week's waterproofing work on our basement. Josh Solomon and Noah Salisbury were diligent in their attention to our questions and concerns, going the extra mile to ensure a quality installation that met our needs. Our basement is already drier and we hope to build it out for a play/rec room soon."

Basement Waterproofing FAQs, answered by experts

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.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.
