Groundworks specializes in helping homeowners with their foundation repair, basement waterproofing, crawl space, and concrete needs. Our top priority is providing high-quality home repair solutions and personalized service across western Pennsylvania. With fully trained technicians, industry-leading products, and nationally backed warranties, Groundworks is here to restore your foundation or basement.

"We hired Groundworks (formerly Baker?s Waterproofing) for a $20,000 basement waterproofing project that was promised to be fast, dust-free, and high-quality. Instead, our home was left coated in concrete dust, parts of the job were rushed, and unsafe wiring still powers our sump pump. Promised electrician service has yet to happen. Three months later, the $10,000 filtration system is still unusable. This project has cost us significant time, caused stress for our family, and left us with ongoing safety concerns. We cannot recommend this company based on our experience. Although one middle manager tried to help and arranged partial repairs, upper management ignored most issues. Three months later, the air filtration system remains unusable, electrical hazards persist, and no restitution has been made. What an exhausting mistake at a deeply personal cost. "

"Josh, the representative from Basement Gurus was outstanding! We had experienced a water issue in our finished basement. Josh thoroughly examined the interior and exterior of the home and determined that the leak might be plumbing related. Josh could have very easily exploited our ignorance and suggested a solution purely beneficial to his company that may not have addressed the underlying cause of the problem. Instead, he demonstrated his integrity by realistically assessing the situation even if it would jeopardize the sale. This is commendable particularly in this era where cutthroat business practices are commonplace. I highly recommend Basement Gurus. They are fortunate to have an employee like Josh who exhibits concern for the customer at such a high level. "

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Williamsport, PA

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.
