"I put a lot of time into my decision of who would waterproof my crawlspace. I had multiple companies come and give estimates. At the end highlander had their best price and a guarantee. Going in I felt confident in my decision. But once the work was done all of the good feelings were gone. From constant miscommunications between sales, workers and bosses. The original work didn’t even fit the original plan. The backyard being more dry as a “result of the pump” never came to fruition. After round 1 of the work all they managed to do was flood the front of my home and make a waterfall in my crawlspace. Round two they fixed the discharge, but when I was told in the estimate that the high end of my home wouldn’t accumulate water because the pump in the low point would collect it and discharge it first. Asked salesman what if it doesn’t he eased my mind by saying “that’s what the warrant is for we would cover it” fast forward to second rainfall after work was corrected and boom standing water everywhere in high end of crawlspace. Then told by the boss they won’t touch it without charging more since not covered by warranty and given salesman stated they don’t charge extra no matter what they find. Turns out the 8600 dollar investment I made was a complete waste and now I’m left with a crawlspace that still floods and if I want it repaired by them it’s another 6000 dollars. But why would I trust a place I’ve already had comeback twice. I wish I could rewind a month and pick one of the other companies, I won’t name any so no one thinks this review is an ad for someone else. My advice is stay away from highlander and don’t trust what they say unless it’s in writing. Now I almost feel trapped as if they have to finish the work but I have little confidence they wouldn’t be out again after the next rain. Only positives are they respond timely and are polite while describing how you were basically deceived. Worst investment I’ve ever made."

Basement Waterproofing questions, answered by experts

Mold can grow anywhere in your home where there’s moisture that doesn’t dry out, usually in areas that are either not ventilated properly or where moisture gathers continuously. Insulation, drywall, and foundations typically provide mold with areas to grow if moisture is present and does not have a chance to dry out. Some of the most common areas in a home for mold growth include:

  • Attic

  • Walls

  • Bathroom

  • Crawlspace

  • Basement

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, standard homeowners insurance policies cover water damage from sudden, accidental damage, like burst pipes and leaking appliances. However, water damage caused by flooding, groundwater seepage, or heavy rain is likely to be excluded from coverage. Check your policy to be sure, as some plans include opt-in flood insurance coverage. Certain companies also allow homeowners to add an optional water backup endorsement to a policy.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.
