Common Causes of Foundation Problems in Central Islip

A home in Central Islip might experience foundation issues for multiple reasons. Some are specific to the local environment, while others are widespread nationwide. They include:

  • Soil composition: Soil with large clay or sand concentrations is highly expansive. In the heavy rainfall Central Islip receives, the soil absorbs moisture like a sponge, then releases it in dry seasons. The constant expansion and contraction puts pressure on nearby foundations, even if the foundations stay dry.
  • Aging plumbing: The average Central Islip home construction year is 1968. If you live in an older home, it's likely to have cast-iron plumbing. When the pipes start eroding, leakage could reach your foundation and even pool beneath it.
  • Topsoil Frost: When temperatures plunge, topsoil abruptly ices over and lower layers can't expand, pushing upper layers to heave and permanently damage infrastructure.
  • Standing water: Water accumulation around your home can threaten 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 structural integrity depends greatly on its foundation. It's important to hire the most qualified crew possible. Center your research on these characteristics:

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. To further understand your contractor's experience, we recommend asking questions about what local codes apply to your project, how its team will draft plans and pull permits, and how the company inspects foundations.

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

Customer Reviews

Before selecting 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. 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, shows more negative reviews than positive ones, and doesn't communicate well, you should avoid working with it.

Lastly, we encourage you to search other platforms, like Trustpilot and Google, for more opinions.

Foundation Repair Cost in Central Islip

What are the different types of foundations in Central Islip?

What are some signs I need foundation waterproofing?

What preventive measures can I take to avoid foundation issues?

You can take several preventive measures to avoid foundation issues:
  • Make sure your home's gutters and downspouts are properly installed and direct water away from your foundation to prevent water accumulation.
  • Water the soil around your foundation evenly, especially during dry spells, to prevent shrinking and expansion.
  • If possible, grade the soil around your home to slope away from your foundation, promoting water drainage and minimizing the risk of foundation issues.
  • Check your foundation for signs of damage, and fix any issues immediately.
