This Old House empowers homeowners with the knowledge and tools they need to tackle various projects and navigate the complexities of homeownership.

Common Causes of Foundation Problems in Union

Some typical reasons why Union homeowners encounter foundation troubles include:

  • Improper modifications: Roofing or landscaping work that wasn't performed properly could lead to your foundation settling.
  • Topsoil Frost: When temperatures plummet, topsoil freezes rapidly and lower layers can't expand, forcing upper layers to heave and permanently damage infrastructure.
  • Aging plumbing: Union has its fair share of older homes, with a median building year of 1954. Many of these properties use cast-iron plumbing. When the pipes start eroding, 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 gathers in areas your drainage system doesn't cover.

How to Choose the Best Foundation Repair Company

Choosing a foundation company doesn't have to be complicated. We encourage you to list what you expect most in a contractor, then evaluate each company on your list against these attributes.

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. Talk to staff to gain more insight into a company's experience. You should ask about local building codes, inspection processes and permit ordinances.

Another way to assess a company's credibility is to look at its website. There, you can learn how long it's been in business and its trade qualifications. It might also share insights and knowledge through blog posts, podcasts, or videos.

Customer Reviews

Before committing to a company, check its online profile with the Better Business Bureau (BBB). You can examine both complaints and positive reviews. 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 properly, you should think twice about working with it.

Lastly, we suggest you search additional sites, like Trustpilot and Google, for additional feedback.

Foundation Repair Cost in Union

The cost of foundation repair can vary quite a bit depending on the extent of the issues and what needs to be done to fix them.
