"I hired Zavza Seal LLC to waterproof the foundation in my basement. Anderson and his crew went above and beyond with the project. They were on time, clean and responsive to any questions I had. I would gladly use them again."

"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"

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."

"They were very helpful and professional. Glen responded to all of my questions in depth and worked hard to get my business to waterproof and eliminate mold. There have been a few hard rains since they completed their work, and I haven't had any water in the basement so far."

"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."

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Holtsville, 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.
