Common Causes of Foundation Problems in Lower Merion

Foundation issues have multiple possible causes. Here are the most frequent ones for Lower Merion residents:

  • Soil composition: Soil with large sand or clay concentrations is highly expansive. In the heavy rainfall Lower Merion gets, the soil absorbs moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction stresses nearby foundations, even if the foundations stay dry.
  • Improper modifications: Landscaping or roofing work that wasn't done properly could lead to your foundation settling.
  • Aging plumbing: Lower Merion has its fair share of older homes, with a median building year of 1959. Many of these properties use cast-iron plumbing. When the pipes start eroding, leakage could reach your foundation and even pool beneath it.
  • Standing water: Pooling water around your home can harm your foundation's integrity, especially when it collects in areas your gutters don't protect.

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 contractor using the following factors:

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. You can also get a sense of a company's experience through what its representatives say. Inquire about its inspection processes, local building regulations, permit-pulling procedures, and fees.

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 the accreditations its team holds. Many leading companies offer educational content for future customers.

Customer Reviews

When you're researching a company's reputation, head to its Better Business Bureau (BBB) profile. There, you can find its "letter grade" rating and a list of customer reviews, both positive experiences and complaints. Remember that negative feedback doesn't necessarily mean a contractor is incompetent. BBB reviews also show how companies handle complaints. A proactive team that aims to achieve amicable outcomes is a good one. Avoid a company if you don't see effective communication about problems.

Foundation Repair Cost in Lower Merion

The price of foundation repair can differ quite significantly depending on the extent of the issues and what's necessary to resolve them.

More complex projects involving excavating, helical piers, or major mudjacking could cost upwards of $7,100. Below are the average foundation repair costs for common issues.
