"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."

"They did a very good job, and if we ever need concrete work again I am sure that we will contact them. Their large crew worked really hard and very fast. Unfortunately, the weather was not cooperating and they had to postpone the work twice, but this was not their fault."

Basement Waterproofing questions, answered by experts

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

Periodic inspections and addressing drainage issues prevent further damage.

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.
