Common Causes of Foundation Problems in Harrisburg

A few common reasons why Harrisburg homeowners suffer from foundation troubles include:

  • Soil composition: Soil with large clay or sand concentrations is highly expansive. In the heavy rainfall Harrisburg 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 stay dry.
  • Topsoil Frost: When temperatures plunge, topsoil abruptly ices over and lower layers can't expand, pushing upper layers to heave and permanently damage infrastructure.
  • Improper modifications: Roofing or landscaping work that wasn't done to standard could lead to your foundation settling.
  • Aging plumbing: Harrisburg has its fair share of older homes, with a median building year of 1964. Many of these properties use cast-iron plumbing. When the pipes start eroding, leaking water could reach your foundation and even pool beneath it.
  • Tree Roots: Tree roots can intrude into a home's foundation through cracks, and may apply force that results in your foundation fracturing, pipes leaking, and overall structural weakening.

How to Choose the Best Foundation Repair Company

Your home's foundation is crucial to its structural integrity, so it's important to work with a reliable foundation repair contractor. Evaluate each provider using the following criteria:

Licensing and Experience

According to the Pennsylvania Attorney General, foundation contractors must register with the commonwealth if they make between $5,000 and $50 million in annual revenue. Registration doesn't involve exams, but it does show a contractor meets bond, insurance, and background check requirements. To further understand your contractor's experience, we recommend asking questions about what local codes apply to your project, how the company inspects foundations, and how its team will draft plans and pull permits.

Contractor websites are among the best places to do your research. Typically, a foundation company will mention how long it's been in business. It might also upload other content to help interested parties.

Customer Reviews

We advise checking the company's Better Business Bureau (BBB) profile to determine whether it's accredited and has a good customer review score. You can check whether other homeowners have expressed satisfaction or filed complaints. Pay special attention to what customers say about company warranties. Remember that complaints don't necessarily mean a contractor is incompetent. BBB comments also show how companies resolve complaints. A proactive team that strives for excellent outcomes is a good one. Steer clear of a company if you don't see effective communication about problems.

Foundation Repair Cost in Harrisburg

The price of foundation repair can range widely depending on the scale of the issues and what's necessary to resolve them. For minor foundation fissures and settling issues, you may pay as little as $1,800. However, if there is significant damage, the normal cost lands at about $2,800. More intricate projects involving tunneling, helical piers, or major mudjacking could cost upwards of $6,800. Below are the average foundation repair costs for common issues.

Frequently Asked Questions About Foundation Repair in Harrisburg

What will I pay to repair my foundation in Harrisburg?

Foundation repair costs about $2,800 in Harrisburg. The final numbers depend on what type of repair you need and how severe the damage is.

When do I need to waterproof my foundation?

Some hints your home needs foundation waterproofing include discoloration or odors, flooding, mold or mildew growth, hairline cracks, uneven floors, and plumbing leaks.

Note that there are two kinds of waterproofing. Interior waterproofing involves installing sump pumps and drains or using sealants around a crawlspace. Exterior waterproofing is usually less expensive. It involves installing exterior drains and creating physical barriers between your foundation and lawn.

What are some "red flags" indicating a foundation company to avoid?

There are several signs that you should avoid a particular foundation contractor. Watch out for unresponsiveness, inadequate credentials, high-pressure sales tactics, lack of insurance, and poor online reviews. Above all, do your research, trust your instincts, and get multiple estimates for the most decision-making power.

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

With today's advancements, foundation repair won't typically disrupt daily routines. If the damage is extensive and the crew believes leaving would be safer, they'll notify you before getting started.

That said, foundation repair crews use industrial machinery, and you'll occasionally experience loud noises or tremors. If either of these will disturb you, you might prefer to leave and return when the crew is finished.
