11 Best Foundation Companies in Herndon, VA

On average, Herndon homeowners pay about $2,735 for foundation repair, although the total cost will vary widely depending on several factors. The fastest way to estimate the cost of a specific job is to ask for quotes from a few local foundation repair companies. The total price will be influenced by things like the size of your house and type of repair(s) needed.

Types of foundation repair include leak repair, crack repair, stabilization, underpinning, and waterproofing.

For both leak repair and crack repair, a technician will come to your home, perform an inspection, and use various measures to remedy leaks or cracks. The amount you spend will vary greatly depending on the size and cause of the problem.

Stabilization reinforces bowing walls by inserting steel or carbon fiber strips. The amount you spend will depend on the material used and the number of strips required. The cost of underpinning also varies. This process, sometimes referred to as leveling or piering, involves underpinning your foundation with concrete piers to level it; the cost will be based on how many piers are needed.

If you're interested in waterproofing your foundation or basement, we recommend looking for a waterproofing specialist. This process might include outdoor waterproofing, indoor waterproofing, or both.

If you're building a new home, have a soil report completed. A soil report will contain information regarding how well your soil can support a foundation, and can give you a heads-up about potential future problems. If your concerns are about an existing house, for a few hundred dollars, you can get an inspection and report by a structural engineer. The engineer can alert you to any current problems that need attention, and advise you on how to avoid future problems.

It's also important that the moisture around your foundation is appropriate. Don't let the soil around your Herndon home get too dry or too wet; at different times, you might find yourself having to reroute your gutters or water your foundation. Also, be on the lookout for leaky pipes or gutters, so you can get them repaired quickly.

Your foundation repair provider should be the one obtaining the permits. You can request that the company provide a detailed explanation of the steps in its process and to see the paperwork and permits it has acquired to make sure everything is properly authorized per Herndon regulations.

Signs that you need foundation waterproofing include discoloration or odors, hairline cracks, basement flooding, white powder or spots on your walls, uneven floors, or signs of fungus, mold, or mildew. Your contractor can tell you whether you need interior or exterior waterproofing.

Interior waterproofing can involve the installation of sump pumps and drains or the use of sealants and generally is less expensive than exterior waterproofing. Exterior waterproofing often involves measures like applying physical barriers to crawl spaces and basements, making changes to your landscaping, or installing exterior drains.

We caution against putting off foundation repairs. A single issue may have an underlying cause that could potentially result in future problems, and it's best to get ahead of the issue as soon as possible. A minor problem now could turn into a large and expensive one in the future if the signs are ignored.
