"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

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. 

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.
