"Erie Homes completed a basement waterproofing for us on 11/20/23. We were impressed and pleased by the professionalism and communication at every phase of the project. Brandon expertly explained the Erie Homes waterproofing system, sump pumps, materials, and warranty and provided us with a quote and pricing details. Having being burned by projects in the past, we came back with a long list of questions and conditions. Brandon answered every single one, made sure that we were completely satisfied with the terms, and added our notes to the contract. Project manager Gage and the team that came to our home was quick and professional. They periodically filled us in on the progress and communicated any changes or concerns. When the project was completed, they walked us through and made sure we were happy with the work before leaving. Since finishing, we have had several rainy weeks and a completely dry basement. Based on the product, work, and customer service, we will be highly recommending Erie Homes to anyone needing basement or waterproofing work."

"Most of the employees were conscientious Work lasted about a week and was the installation of a waterproofing system in my interior basement. The cement over the drain is very uneven with the existing flooring in much of the area. No way could carpet be used after this. Anyone contemplating this same kind of work should specify floor must be level and ask to see actual material covering the walls, not just pictures to avoid surprises. Clearly much of my disappointment would have been avoided if I had been more fastidious in my specifications and investigations."

"Austin was extremely professional and did very nice work. We had grading issues near the house and Austin helped craft a solution with me and then made it happen. I had struggled with other contractors in the area returning calls, not showing up when they said they would, and a variety of other issues - I did not have any of those issues with Clear View Land Management LLC. They showed up when they said they would, did what they said they were going to, and the price was very reasonable. I've included a few before photos of our issue, and then after the grading, and then after they were finished."

"The work Everdry performed was excellent and The team was very professional and helpful through the whole process. Even today they are just a phone call away with any questions or anything I have about the work they perfomed in 2021. Along with that I haven't seen a leak or anything the basement drier than it has ever been and I couldn't thank them enough for all they did. 10/10 would recommend to anyone who needs their basement waterproof or looked at."

"The weather interfered the day they were first to come and utilities didn’t measur and m ark in a timely matter but Rion came on time left when they said they would. They were clean and cleaned up and the workers were nice and considerate, especially with my neighbors I was concerned about hiring a basement waterproofer but I would recommend them without reservation. I love my egress window. What a difference it makes."

Basement Waterproofing questions, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.
