Is a warranty included with your waterproofing services?

Yes. Most of our basement waterproofing solutions come with a lifetime transferable warranty, giving you long-term peace of mind. This warranty covers both the materials and the workmanship involved, and because it’s transferable, it can even increase your home’s resale value. At Accu-Dry, we stand behind our work and are committed to providing durable, effective protection for your home.

Does Accu-Dry handle permits?

Absolutely.

Our team handles the paperwork so you don’t have to worry about a thing.

How long does basement waterproofing take?

The timeline for basement waterproofing depends on the complexity of the work. Many interior systems—such as sump pump installations or drain tile systems—can be completed in one to two days. Larger-scale projects, like exterior excavation and foundation sealing, may take two to three days or more.At Accu-Dry, we provide a clear project timeline before work begins and aim to complete the job efficiently while minimizing disruption to your daily routine.

Will basement waterproofing eliminate mold?

Yes, professional basement waterproofing can significantly reduce and help eliminate mold by addressing the root cause—excess moisture. Mold needs water to grow, and when a basement is properly sealed and drained, the damp environment that allows mold to thrive is removed.Accu-Dry’s waterproofing systems create a dry, stable space that makes it difficult for mold to develop or return. While mold remediation may be needed for existing growth, waterproofing is essential for long-term prevention.

How much does basement waterproofing cost?

The cost of basement waterproofing varies depending on factors such as the size of the basement, the severity of the moisture problem, and the chosen solution. Small repairs like crack sealing may be relatively affordable, while more comprehensive systems—such as interior drainage, sump pump installation, or exterior membrane applications—can require a larger investment.At Accu-Dry, we provide free inspections and detailed estimates, so homeowners can understand the scope and cost before making any decisions. Our quotes are clear, competitive, and customized to your specific needs.

Where Is Water Entering Your Basement?

Scroll to see affected areas and learn more about common causes and repair solutions.

Sill Plate Seepage

(Hydrostatic Pressure)

Sill plate seepage refers to water that comes running over the top of the foundation wall. Of all seepage types over the top may be the least common but it is a straightforward method of repair.

Foundation Seepage

(Cracks, Sewer and water line)

Your home’s foundation is the backbone of your house, and it’s crucial that it remains sturdy and intact. However, foundation cracks are a common issue that can lead to seepage and other problems. If you’re facing foundation crack seepage, it’s important to understand the causes and take the necessary steps to fix the problem. In this blog post, we’ll go over what you need to know about foundation crack seepage and how to address it.

Window Well Seepage

Windows and window wells exist for a few reasons. The windows themselves allow natural light to enter the basement helping with the air quality and health of a natural dark, humid environment prime for bacteria and mold growth.

Egress windows are a large window installed in a basement by code which allows an occupant to exit the basement in case of a home fire.

The integrity of these windows are protected by a metal casing called a window well. They are meant to keep exterior dirt from caving into the dig out area and keep water from building up and coming through the window itself. Unfortunately, like everything outdoors in the Midwest nothing lasts forever due to the harsh weather extremes of all four seasons.

Floor Seepage

(Hydrostatic Pressure)

Basement floor seepage or “ground water” is caused by hydrostatic pressure. It occurs when water accumulates under the home causing the water table to rise and put upward pressure on the basement floor. If you have floor seepage it will typically show itself seeping through the “cove joint” of your basement or crawlspace.

The cove joint is the spot where the concrete basement floor meets the vertical foundation wall. Since the floor and the wall are poured at separate times there is a small void that water comes up through. This pressure can lead to a range of problems, including floor cracks and in rare occasions even structural damage.

Cinder Block Foundation Wall Seepage

Newer homes are built with a poured foundation wall, but some older homes were built with cinder blocks and present different seepage problems than a poured foundation wall.

Internal drain tile system with 90 mil antimicrobial foundation wall liner:

Internal drainage systems are always the superior option for alleviating cinder block wall seepage for many reasons. The biggest reason is that internal drainage systems carry a lifetime unlimited transferable warranty since it is protected from the harsh exterior elements. The industry standard warranty for exterior repairs such as a membrane carry limited 10-15 year warranties since the repairs are exposed to the harsh weather elements of the Midwest seasons.

Showed up on time. Excellent communications. Went above by shop vacuuming the water out of the crawl space. Did the work and no more water in the basement. I thought it was a reasonable price for the work that had to be done. I would happily hire them again.
