"Noticed a crack a few years ago, this year noticed it was bigger. Got 2 estimates. Not only was Locktight a better price, but the estimate was prompt, the guys worked fast and efficiently, nearly no disturbance to the area. Dug down (by hand!!) identified the broken elbow fitting in pipe, replaced it, waterproofed and sealed crack. Super professional. Would highly recommend."
Another happy customer!
Clay drain tile removal.  FACT: With WNY being an older development in most areas, clay drain tile was used in the basements to lower the water table.  Over time, clay deteriorates which leaves you with cracked, broken and defective drain tile.  This leads to water backing up into your basement causing mold, mildew & damage to your foundation.

"I called numerous companies to give me an estimate on waterproofing our basement. Brandon was quick to respond and was able to address the problem and find a solution that was directed at the specific issue. Highlander was easy to work with and actually enjoyed having the entire crew at the house. They went above and beyond answering any questions with a guarantee and cost that I could live with. I highly recommend Highlander to anyone looking to fix a damp basement."

"My rear facade wall was falling apart, there was apparent deterioration, cracks falling apart. I was recommended to High Tech by our community board. Scaffold was used for this project. They chipped out the 4-story facade and applied wire-mash. First coat of cement was for curing and the second coat was  the finishing coat. The finishing coat was very finely re-finished. The back-wall was waterproofed with thoro-coat.  My roof was leaking as well at multiple places, bubbles had been formed with water seeping in, leaving into my kitchen. The weather was very rainy and stormy at that time and thanks to High Tech they repaired my roof by placing a new layer roof on top of the existing roof and stopped the leak. High Tech remains as one of the top recommended company in our community board."

Basement Waterproofing questions, answered by experts

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

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.

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.

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.
