"We are extremely pleased with the job Enviropro did in our basement. The price was reasonable (relative to others we contacted), and the sales call was friendly without the high-pressure nonsense of some other waterproofers. One key to my decision to hire them is that the Lifetime Warranty is backed not just by EnviroPro, but also by the national company that created the system they use. The work was done according to schedule, with far less dust and mess than we expected. The crew were very communicative and they cleaned up after themselves. It's like having a brand new basement. We couldn't be happier, and do not hesitate to recommend Mike and his staff."

"My crew were highly skilled and hard working. They were also very polite and cooperative when I asked them to cover what my tenant needed to leave in the basement during the waterproofing operation. All the work was completed in the 2 days they promised. They cleaned up all the debris when the job was finished."

"Working with Just Dry Basements was best described as no-nonsense, fast, and high-quality. In a highly-charged emotional situation like a basement flooding - it is easy to just pick someone to do the work out of desperation. I was lucky enough to work with JDB, who not only rapidly assessed, made a plan together on how we would approach the job, and accommodated a difficult situation where the basement was mostly finished, and they had to carefully deconstruct some of the walls to put in the proper mitigation. A year plus later and a LOT of rain past, the work truly stands the test of time and whatever the elements can throw at it. I have since worked with JDB on other projects, and not just because of the quality of work, but also their fair pricing, friendly and predictable communication, as well as standing behind their work 100%."

Basement Waterproofing questions, answered by experts

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.

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. 

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
