Common Causes of Foundation Problems in Leesburg

Some frequent reasons why Leesburg homeowners experience foundation issues include:

  • Soil composition: Soil with large clay or sand concentrations is highly expansive. In the heavy rainfall Leesburg experiences, the soil absorbs moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction presses against nearby foundations, even if the foundations keep dry.
  • Topsoil Frost: When temperatures plummet, topsoil abruptly ices over and lower layers can't expand, pushing upper layers to heave and permanently damage infrastructure.
  • Improper modifications: Landscaping or roofing work that wasn't performed to standard could result in your foundation settling.
  • Aging plumbing: While many Leesburg homes are fairly new, some still use cast-iron plumbing. When the pipes start eroding, leakage could reach your foundation and even pool beneath it.

How to Choose the Best Foundation Repair Company

To pick a foundation repair contractor, you should determine what's most important to you. Use this list of attributes to help you go through the process.

Licensing and Experience

The Virginia Department of Professional and Occupational Regulation issues licenses to foundation repair companies. The license a company has determines what work it can do and what size projects it can handle. To further understand your contractor's experience, we recommend asking questions about how its team will draft plans and pull permits, how the company inspects foundations, and what local codes apply to your project.

One of the most effective ways to evaluate a company's reputation is to visit its website. Look for the company's history and the qualifications its team holds. Many prominent companies publish educational content for future customers.

Customer Reviews

Before committing to a company, check its online profile with the Better Business Bureau (BBB). You can examine both positive reviews and complaints. Complaints aren't necessarily a red flag in themselves. You want to discover how a company handles them. If the management team proactively and consistently resolves issues, it's a good sign. However, if the company lacks accreditation, has an abundance of negative feedback, and doesn't communicate effectively, you should avoid working with it.

Lastly, we encourage you to search different websites, such as Trustpilot and Google, for more opinions.
