"I recently had the pleasure of working with Stay Dry Waterproofing and I can confidently say that they are the best waterproofing company in town. From start to finish, their team of experts were professional, knowledgeable, and attentive to my needs. The project manager, Brock, was fantastic to work with. He took the time to thoroughly explain the waterproofing process and answered all of my questions with patience and expertise. He also provided a detailed timeline for the project, which helped me plan accordingly. The installation crew arrived on time and worked diligently to complete the project on schedule. They were respectful of my property, kept the work area clean, and were mindful of noise levels. Overall, I was extremely satisfied with the quality of work and level of service provided by Stay Dry Waterproofing. My basement is now completely dry and I have peace of mind knowing that my home is protected from water damage. I highly recommend this company to anyone in need of waterproofing services. They truly deserve 5 stars!"

"We hired Travis to straighten a 24' brick planter that had developed a severe bow and had motar issues. Travis and his crew were prompt, professional, and finished the work on time. Even with heavy rain delaying the project, the office called each day until they could start. When finished, the planter looked better than when first built. Also, the clean up was amazing. One would think work and customer service of this quality woukd be expensive. But, no, the cost was very reasonable. We highly recommend Travis / Bucklew Basement Waterproofing and Masony Repair."

"Needed a waterproofing company to waterproof my damaged basement, excellent workmanship, exceeded my expectation. The workers were very polite and knowledgeable. Completed the job in one day. Removed concrete flooring, install indoor water gutters, drilled several weep holes, removed old sump basin and sump pumps, installed new equipment, they also install a rubber barrier to guide water to the gutters and placed new concrete where needed. They removed all debris, the basement looked cleaner than before they started. I was impressed with the quality and value of Ohio Basement Authorities service. I would highly recommend this company. Good price and excellent service."

"Mid-State Basement Systems came highly recommended by a good friend from Buffalo, NY and they did not disappoint. From start to finish they were very professional yet personable. Larry & Phil in the initial stages of the basement inspection and a reasonable quote. Silvino and his team who done the actual work was incredible, done with absolute excellence. They were here when they said they would be and finished the job a day ahead of schedule. I am thoroughly pleased with this company, first class. I highly recommend them if you need work done on your basement.******"

Basement Waterproofing questions, answered by experts

In Delaware, if you notice new water stains after heavy rainfall, persistent dampness along the foundation, or mineral deposits forming on walls, your waterproofing may be failing. Watch for shifting or uneven basement floors, increased condensation on pipes, or a musty smell that lingers even after cleaning. These issues, especially in areas with clay-rich soil and fluctuating groundwater, suggest your moisture barrier or drainage system needs attention.

Helpful?

In Delaware, if you spot damp patches that spread after storms, hairline cracks that expand seasonally, or efflorescence that worsens over time, these are early warnings. An uptick in sump pump activity or rising humidity despite ventilation also signals underlying drainage issues. Addressing these problems quickly is crucial, as Delaware’s variable weather and soil conditions can accelerate minor issues into major foundation repairs.

Helpful?

New homeowners in Delaware should begin with a comprehensive assessment of their basement’s foundation drainage and moisture barrier systems. Prioritize grading the landscape to direct water away from the home, extending downspouts, and inspecting the sump pump. Sealing foundation cracks and waterproofing window wells are essential, especially in regions prone to heavy rain or high water tables. Installing a vapor barrier or dehumidifier can further protect against local humidity.

Helpful?

Delaware homeowners should start spring by inspecting for leaks after snowmelt and ensuring exterior drains are clear. In summer, monitor indoor humidity and check for condensation on walls or windows. Fall is ideal for cleaning gutters, checking foundation drainage, and sealing small cracks. During winter, look for ice buildup near the foundation and test your sump pump. Regular, season-specific checks help prevent moisture issues year-round.

Helpful?

In OH, immediate action is needed if you see active leaks, structural cracks wider than ¼ inch, or mold growth, as these can quickly worsen. If you notice minor seepage, faint musty odors, or small cracks, plan to address them within a month, ideally before the rainy season. Preventive upgrades like adding a moisture barrier or improving exterior drainage can be scheduled, but prioritize urgent repairs first.
