"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

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

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.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

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.
