"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

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

Water damage always poses the risk of mold, but if you act quickly enough (within the first 24 hours), you may be able to avoid mold growth resulting from water damage. Clean up the water quickly and thoroughly dry the area. If the issue is more extensive or you didn’t act quickly enough, it’s always safer to assume mold has grown and hire a mold inspector to examine the area.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.
