Common Causes of Foundation Problems in Smithtown

Foundation issues have multiple possible causes. Here are the top ones for Smithtown residents:

  • Standing water: Water accumulation around your home can be menacing to your foundation's integrity, especially when it gathers in areas your gutter system doesn't reach.
  • Soil composition: Soil with large sand or clay concentrations is highly expansive. In the heavy rainfall Smithtown receives, 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 keep dry.
  • Topsoil Frost: When temperatures plummet, topsoil freezes rapidly and lower layers can't expand, forcing upper layers to heave and permanently damage infrastructure.
  • Tree Roots: Tree roots can intrude into a home's foundation through cracks, and may exert pressure that leads to your foundation breaking, pipes being damaged, and overall structural weakening.

How to Choose the Best Foundation Repair Company

When choosing a foundation company, you should consider your personal priorities. Ask each provider on your list about the following qualities.

Licensing and Experience

New York's state government doesn't issue contracting licenses, but cities often choose to require them of foundation companies and other builders. For example, New York City requires foundation and excavating contractors to obtain a "Safety Registration Number" with a concrete work endorsement. They also need to register as a general contractor or home improvement contractor. You can also get a sense of a company's experience through the details its representatives share. Inquire about its inspection processes, local code requirements, permit-pulling procedures, and fees. One of the simplest ways to evaluate a company's reputation is to go to its website. Look for the company's history and the accreditations its team holds. Many well-known companies offer educational content for future customers.

Customer Reviews

Before choosing a company, check its online profile with the Better Business Bureau (BBB). You can examine both complaints and positive reviews. Remember that complaints don't necessarily mean a contractor is incompetent. BBB comments also show how companies handle complaints. A proactive team that strives for excellent outcomes is a good one. Steer clear of a business if you don't see effective communication about problems.

Foundation Repair Cost in Smithtown

The cost of foundation repair can differ significantly depending on the severity of the issues and what needs to be done to fix 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 will likely fall around $2,900. More complex jobs involving excavation, helical piers, or major mudjacking could cost $6,900 or more.

Below are the average foundation repair costs for common issues.

Common Foundation Repair ServicesAverage Cost
Crack Repair$343
Leak Repair$2,742
