"Erie Home Basement Solutions was a pleasure to work with. Everyone was on time, and always polite and courteous throughout this process. This is extremely hard work and they continued to always have a smile on their face and answer any questions I had. They worked diligently to complete the project on time and fulfilled all aspects of the contract. Actually, they went above and beyond to make sure I was pleased with their service, which is unusual in todayâ s work culture. I would highly recommend this company for your basement waterproofing needs."

"Although I did not hire them, I was impressed by their honesty. He explained what the problem was, and told me that it could best be solved by a carpenter, as it was not a cement foundation problem as I thought it was. He also gave a price range of what he thought it would cost. Would hire if I had a problem."

"Central Wisconsin Excavating (CWE) did a fantastic job on our project. They built a solid, well-prepared foundation for our 80,000-bushel grain bin and graded our driveways perfectly to ensure water drains away from our buildings. Their attention to detail, quality of work, and professionalism really stood out. The site was left clean and properly finished, and everything was done right the first time. We’re extremely happy with the results and would highly recommend CWE to anyone needing excavation or site work done right."

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."

"I was concerned that I had mold on my basement walls.  Rich assured me that it was not mold on my basement walls.  However, he did find some mold on the wood on the ceiling.  But he told me that I could wash that off myself and he told me how to do it.  I have medical issues  and my husband is 70 years old.  We are going to try to do this ourselves.  But if we are physically unable to do it, we will most certainly use Rich and his team.  Rich seemed very knowledgeable and was very friendly.  He did not charge me for the assessment even though he took time out of his schedule to come to my house and assess my basement.

Basement Waterproofing FAQs, answered by experts

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.
