"

About 6 men did the work. They were very organized. They covered the path from the door to the basement where the inside work was done. They were polite, professional. The foreman kept us abreast of progress. He did took seriously questions that my wife and I had. He did not talk down to my wife. They moved and covered up everything in the basement with plastic. I had moved a lot of  stuff out ahead of time. They dug about a one foot wide trench along the inside  perimeter of the basement, installed drain pipe and re-cemented with several vents. The pipe runs to the new sump pump. They did repairs and drainage on the outside perimeter as well. Everything was hooked up to pre-existing storm drains. The work took three days.

My only mild complaint is that the utility sink in the basement pitches slightly forward, and so it does not drain as completely as it should. I did not ask them to fix it.

We had this done in response to water in the basement. We did not have a sump pump prior to this and had 9 inches of water in the basement last February. We have not had much rain, and so I cannot verify that all is OK, but it seems to be at this point.

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."

Basement Waterproofing questions, answered by experts

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.
