"We just finished a big project, big for us, and couldn't be happier with the workers. Dave has been a great help clarifying an issue and the foreman Steve has kept up up to date with every move they are making. The workers Joey and Tony were polite and did all they could to keep the dust and dirt to a minimum. That was a tough job working in a crawl space and having to enter and exit the house in the snow and bad weather. Other craftsmen (that's all I can call them, they were so in tuned to what they were doing) came in during the week to lend a hand, and they too were top notch. I will say, I am sure not everyone wouldn't mind the dirt tracked through the house, but they made every effort to clean up the last crumb. Thirty years ago Woodford Bros. added a large addition to our house and couldn't think of any other company that we would think of using. We are happy to refer Woodford Bros to anyone!"

"ErieHome waterproofed my basement. The crew was polite, kind, and came in, did an excellent job in 3 days by digging a trench on the inside of the basement, removing the dirt from the bottom of the foundation, installed corrugated tubing, rock and then cement. They also installed a Humidex airpurifier and new sump pump with a backup pump. They cleaned up afterward. Any questions I had were answered in a respectful manor. I now have peace of mind knowing that I no longer have to monitor weather forecasts for rain or have to clean up anymore incoming water. The system is warranted for the life of the house and included within the price, which increased the value of my home."

"Great company to work with, very friendly knowledgeable people and customer satisfaction is their goal. Matt and his crew did a superb job restoring our finished basement after it got flooded when our sump pump had failed during heavy rains. Dual pumps were installed, along with waterproof and mold proof walls and flooring and a Sedona dehumidifier air purification system."

"Rich and his team did a fantastic job on waterproofing my basement. I had many folks over for a quote and the vast majority of them spent hours of my time and quoted me very large prices on installing a waterproofing system. Rich came over, explained what work could be done, quoted a simple price, and left it at that. The crew was professional, timely, friendly, and thoughtful. They even provided sone minor fixes to some outside concrete items free of charge which saved from having to call out another crew for additional work. I highly recommend R. Davies if you want a professional crew who can get a job done efficiently and honestly."

"In response to my initial email inquiry, Eric, the owner, came to the house and we discussed all of the issues and how they would deal with them. He took measurements and pictures and was very professional, polite and encouraging. Within a few days he emailed me a very precise and detailed proposal outlining all three jobs and the estimated cost. I immediately accepted. Adam came to the house and took some more measurements and pictures and said the work would begin the following week and take three days. The required permits were taken care of right away. As scheduled, Paul (the onsite foreman), Lloyd and TJ showed up and began to work. Braces were installed against the basement wall after the cracks were repaired. On the exterior a French drain was put in along the side of the house extending to the ditch out front. The old walkout was excavated and a new permentry door was installed. The work went as planned with no problems and was finished in three days. All debris was taken care of and they cleaned up when they were through. All of my questions and concerns were answered. Adam followed up the day after the work was completed to see if I was satisfied and to answer any additional questions. I also must give kudos to Cynthia, the office manager, who made the paperwork and payment process smooth and effortless. The quality of the work and the quality of the employees is just exceptional.

Basement Waterproofing FAQs, answered by experts

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Periodic inspections and addressing drainage issues prevent further damage.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

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

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.
