"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

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

It can be safe to live in a house with minor foundation problems as long as the issues are checked and monitored by a professional. Minor cracks are rarely a cause for structural concerns, but signs of leaks, sinking, or bulging walls should be strongly scrutinized by a foundation specialist. Similarly, it's always smart to hire a professional when you're concerned about buying a house with foundation repairs.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

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.

Ductwork sweats for the same reason you might find beading on your windows or why cold drinks drip in the heat—temperature difference. When you see your ductwork and you notice sweating, that's a sure sign that your system is not operating anywhere close to peak efficiency. The best way to keep ductwork from sweating is to wrap it in inadequate insulation.
