"Tarheel encapsulated our crawlspace. They cleaned out the bulk of the debris and sprayed fungicide. They also managed to knock over a post jack. The second day they put a sump pump and replaced the old insulation They installed reinforced plastic sheeting, including over the base of the fallen post jack. The insulation began falling within a few hours of the crew leaving. They did send a second crew to fix this. Our older furnace depends on the under-house vents to breathe. These were all sealed up. The furnace pulled combustion air out of the house until I cut the vents open. In digging the sump well (at one of the highest points of the crawlspace) they cracked the sewer line, which let gravel fall in. Whenever the drains back up enough, the sump pump sends raw sewage out to the front yard. I am currently waiting for an estimate from the plumber to replace the broken sewer pipe and move the sump pump. I have called to discuss this and hope to eventually get a return call."

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.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

Finishing an unfinished basement adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Mold and mildew are always a primary risk with any water damage, but it’s not guaranteed that mold will grow. The chances of mold growth are dependent on many factors, such as the severity of the damage and how quickly the area was cleaned up and dried out—that’s why responding to water damage immediately is imperative. If you suspect you have mold and mildew growth, you should talk to a local mold removal expert .
