"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts. The home was built in the 1940's and the basement would flood following rain. Since the repairs, three rain storms within five weeks, each with over 3 inches of rain, have occurred and the basement waterproofing project was immediately tested. It has remained dry!"

"I own discount cesspool and drain inc, ive been using Mike for over 10 years! His work is always perfect. He gives me and many new home owners the more resonable prices ever! Mike always comes on time and gives me a free in person estimate. If his price is higher than other contractors he beats the other price quoted by $500 every time. One of my favorite parts about this conpany is that they are family owned and operated. I highly recommend thid company to anyone looking for beautiful work, foundations, waterproofing, Ashphault work, brick and masnary work!! Thanks again Mike and Jim!!! -Dom Motta, president of Discount Cesspool and Drain Inc"

"Alex was amazing!! We had a crack in our foundation that another company attempted to repair numerous times. We were fortunate enough to hear about ProSeal and I am happy to report not only did Alex repair the crack to near perfection but the work was done timely, neatly and his customer service skills are top notch. I would HIGHLY recommend ProSeal for all of your foundation needs."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

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

Yes, crawl space encapsulation is a good investment. It improves your home's energy efficiency and air quality, boosting its value. With routine inspections and maintenance, encapsulation provides a long-lasting solution to moisture and pest issues. Regular check-ups protect your investment, enhance energy efficiency, and maintain your home's structural integrity. If your home is prone to pests or moisture seepage, encapsulating your crawl space is definitely worth it.

A vapor barrier is a thin sheet of plastic that prevents moisture from seeping into your crawl space, while insulation prevents unconditioned air from entering. Combining both insulation and a vapor barrier creates a dry, temperature-stable environment. Some insulation products serve both purposes, enhancing energy efficiency and protecting against moisture and temperature fluctuations.
