"The rooftop of our apartment building had leaks that lasted several years and patchwork repairs from different contractors never resolved the ongoing leak issue. The building board interviewed several contractors, all of whom wanted to entirely replace the roof for a very high price. Atif (owner) was able to isolate the problem area of the roof without replacing the entire roof at a much lower price point with a guarantee. The work was done quickly and efficiently. I highly recommend Atif and his team for their professionalism, dedication and most of all honesty. It’s been 3 years (with severe storms) and we haven’t had a leak since 😃. "

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Yonkers, NY

Standing water in your crawl space won’t disappear on its own. Keep the drainage clear, ensure the vents are working properly, and run a dehumidifier to control moisture levels. If dampness lingers, mold, wood rot, and foundation cracks can follow. Act quickly and call a pro to protect your home’s structure and indoor air quality.

Disinfecting a crawl space requires a methodical approach. First, clear all debris and remove old liners and insulation to eliminate contaminants. Then, apply a strong bleach solution or borate spray to eradicate mold spores and mildew. Ensuring complete surface coverage and allowing ample drying time establishes a sanitary environment and prevents future infestations.

A crawl space serves vital functions by providing access to essential systems, including electrical wiring, plumbing, and HVAC ducts. It also offers a buffer zone that aids in moisture control and protects underlying structural components. 

Yes, crawl space encapsulation is a worthwhile investment in protecting your home. Crawl space encapsulation locks out moisture, controls humidity, and blocks pests and harmful pollutants like radon gas. Those benefits boost indoor air quality and protect beams, joists, and insulation, giving your home long‑term structural stability and safeguarding your family’s health.

Prevention is the best way to keep water out of your crawl space. A dehumidifier and sump pump can help control moisture levels, but grading the landscape to redirect water away from the foundation is most important. Additionally, seal foundation cracks and install reliable drainage systems such as a French drain to maintain a consistently dry environment.

Yes, repairing your crawl space foundation is critical, regardless of how minor the issue may seem. Foundation problems arise from enduring moisture, water intrusion, and unstable soil, which can lead to significant structural damage if left unaddressed. Hiring a licensed structural engineer or foundation repair professional guarantees your home’s long-term stability and safety while preventing escalating repair costs.
