Common Causes of Foundation Problems in Hilton Head Island

A few typical reasons why Hilton Head Island homeowners experience foundation troubles include:

  • Improper modifications: Landscaping or roofing work that wasn't done to standard could result in your foundation settling.
  • Soil composition: Soil with large sand or clay concentrations is highly expansive. In the heavy rainfall Hilton Head Island experiences, the soil soaks up moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction presses against nearby foundations, even if the foundations stay dry.
  • Aging plumbing: While many Hilton Head Island homes are fairly new, some still use cast-iron plumbing. When the pipes start to erode, leaking water could reach your foundation and even pool beneath it.
  • Standing water: Standing water around your home can harm your foundation, especially when it collects in areas your drainage system doesn't protect.
  • Tree Roots: Tree roots can encroach on a home's foundation through cracks, and may apply force that causes your foundation fracturing, pipes being damaged, and overall structural deterioration.

How to Choose the Best Foundation Repair Company

Your home's foundation is crucial to its stability, so it's important to work with a reliable foundation repair company. Assess each firm using the following factors:

Licensing and Experience

According to the South Carolina Department of Labor, Licensing, and Regulation, foundation repair companies need a general contractor's license. Contractors that do not perform commercial work can pursue licensure from the Residential Builders Commission. To further understand your contractor's experience, we recommend asking questions about how the company inspects foundations, what local codes apply to your project, and how its team will draft plans and pull permits.

One of the best ways to assess a company's reputation is to find its website. Look for the company's years in business and what credentials its team holds. Many top companies provide educational content for potential customers.

Customer Reviews

Before choosing a company, examine 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. Instead, discover how a company manages them. If the management team proactively and consistently resolves issues, it's a good sign. However, if the company lacks accreditation, has more negative reviews, and doesn't communicate properly, you should avoid working with it.

Finally, we encourage you to search different websites, such as Trustpilot and Google, for other reviews.

Foundation Repair Cost in Hilton Head Island

The price of foundation repair can differ quite significantly depending on the extent of the issues and what's required to resolve them. For minor foundation cracking and settling issues, you may pay as little as $1,800. However, if there is considerable deterioration, the average cost lands at about $2,300. More involved projects involving excavating, helical piers, or major mudjacking could cost upwards of $6,600. Below are the average foundation repair costs for common issues.

When would I need a foundation replacement, and when could I just get a repair?

Most foundation issues don't require replacement to fix them. In rare cases, a foundation might warrant total reconstruction. However, if you pay attention to early warning signs like cracking walls or uneven doors, you probably won't need replacement.

What's the most popular foundation type in Hilton Head Island?

Hilton Head Island-area homes use several foundation types, from concrete slabs and pier-and-beam foundations to crawlspaces and basements.

Will foundation repair disrupt my daily routine while the work's being done?

You don't need to leave your home for foundation work. The latest technology allows exceptional results with minimal digging and disruption. However, the crew will still use industrial machinery, and you will still hear loud noises and feel vibration while they're working. If these would annoy you, you can always choose to leave and come back when the crew is completed.
