Basement Man is your locally owned and operated basement waterproofing specialist. We stand behind and guarantee all of our work, so give us a call anytime for a free estimate.

"I'm renovating an old zombie house, and the basement was in terrible shape - humid, cracked floors and walls and foundation issues both inside and out. I met with several contractors, but most only focused on their own niche, never offering a comprehensive fix. Then I met Jack - Basement Man. He was the only one who looked at the full picture and pointed out issues that others missed. Jack was professional, thorough and honest. He took the time to walk me through my options, never trying to be pushy or upsell me on things I didn't need. He was on-site everyday, led a hard-working team, and turned my basement into a clean, solid and completely revitalized space. His communication was consistent and clear throughout the project. The results were beyond my expectations. I'd hire him again in a heartbeat and highly recommend him to anyone with basement and foundation challenges."

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

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
