"

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."

"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

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.
