"Great company to work with, very friendly knowledgeable people and customer satisfaction is their goal. Matt and his crew did a superb job restoring our finished basement after it got flooded when our sump pump had failed during heavy rains. Dual pumps were installed, along with waterproof and mold proof walls and flooring and a Sedona dehumidifier air purification system."

"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 FAQs, answered by experts

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.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

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.

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.
