"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

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Interlocking garage tiles made with PVC are the most effective for garages with past issues of humidity and flooding because damp concrete is not suitable for paint. Epoxy coating is also water-resistant and can prevent mold buildup. Finally, porcelain tiles are a wonderful option for wet conditions if your budget allows.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.
