"Hired G&R to fix up my deck, stain it, and paint a shed. The work involved replacing all of the horizontal hand rails, and tightening the floor boards. G&R stained the entire deck by hand (including the lattice work). Gave me a good price and stayed with that price. The deck was 35 years old, but you couldn't tell by looking at it now. My neighbor hired them to do some landscaping work after seeing them work on my property. Willie was easy to work with. Would definitely hired them again."

"Fausto and his team were great! I would have no hesitation in using them again. I had the attic space of a two-family building insulated with blown-in cellulose. I had already used Tigasi Home Improvement for a smaller Rockwool basement ceiling job and they were very reasonable in price, thorough and clean so I turned to them for this project. Again they gave me what I thought was a reasonable quote for removing old insulation, sealing gaps and then insulation, and Fausto explained the process well. He was very patient and understanding with my tenants' concerns, as access was via a drop down ladder in one unit's hallway. I also wanted an extended platform for storage in the attic and they were able to sort this out for a reasonable price.The team kept the job site extremely tidy and they were pleasant throughout. I would not hesitate to use Tigasi gain for another project. Plus I found them to be just really, really nice guys! A before pic and some after here."

"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."

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