"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

A crawl space is an area under the house that provides access to plumbing, electrical, heating ducts, and other HVAC units. Its purpose is to create a buffer between the ground and the living area, helping with ventilation, moisture control, and access for maintenance or repairs. Crawl spaces are most often seen in houses in North America which are built on concrete foundations versus other parts of the world where buildings are constructed differently.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.
