Exterior Waterproofing Experts is a Class A General Contractor in the state of Virginia since 1997. Our service protects your home against wet basements, water leaks, flooding, water seepage, foundation leaking, and wall seepage. We have been doing subcontract grading and drainage work for many years. We have completed many waterproofing contracts for residents of Fairfax County, including: Fairfax, Alexandria, Arlington, McLean, Great Falls, Potomac, and Vienna, Virginia (VA). We are now offering to work directly for clients, passing the savings on to the homeowners. It is our belief that water problems are best solved from the outside before water gets into your home.

"My basement had mold and evidence of water damage in July/August, and I was referred to Exterior Waterproofing Experts. The majority of the mold was on the side of my house, but the salesperson made a strong pitch about the need to waterproof the front of my home by digging up the garden down to the foundation. My wife was largely convinced, so we went ahead with the $8000 project. Six months later, the insulation behind the waterproofed front of the house is sopping wet. When the salesperson came back to my home to take a look, his explanation was that the water probably came up through the floor. His words were along the lines of "99% of the time the water comes up through the front." At this point, I feel like I have an expensive solution to a problem I didn't really have."

"I highly recommend NV Waterproofing & Foundation Repair! The work crew, Alfredo, David, and Javier were excellent! Alfredo Hernandez, the Foreman, kept me updated every step of the process, thoroughly answered every question I had, and addressed all concerns with expert problem solving and skill. These three men were in my home for a couple weeks doing extensive foundation and waterproofing work. They were always professional, courteous, and kept the work space clean. I was able to leave home for appointments with full confidence and trust in this crew. The sales manger, Brendan Feehan, was incredibly knowledgeable as well, and was able to solve every problem with my complex foundation and waterproofing issues.

Foundation Repair questions, answered by experts

Foundation repair can affect home value positively or negatively. If you address the underlying issue and hire a foundation repair contractor to complete the work—especially one that includes a warranty for the work—then your repair will likely increase your home’s value. If you fail to pull proper permits and cannot prove that a licensed expert completed the work, there’s a chance buyers will view your home in a negative light and end up offering less for your property.

Foundation repairs typically require a building permit, depending on the state and local jurisdiction. Make sure your contractor follows all building codes, and a local building inspector will review all work to ensure that it is up to code. Not following local building codes can prevent the sale of your home and potentially put your home at an even greater risk of damage if the work isn’t done properly. You can call your local municipal office to confirm that your contractor has filed the necessary permits.

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.
