Common Causes of Foundation Problems in Kent

A few frequent reasons why Kent homeowners encounter foundation issues include:

  • Soil composition: Soil with large sand or clay concentrations is highly expansive. In the heavy rainfall Kent gets, 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 stay dry.
  • Improper modifications: Landscaping or roofing work that wasn't performed to standard could lead to your foundation settling.
  • Standing water: Standing water around your home can threaten your foundation's integrity, especially when it gathers in areas your drainage system doesn't cover.
  • Aging plumbing: While many Kent homes are fairly new, some still use cast-iron plumbing. When the pipes start eroding, leakage could reach your foundation and even pool beneath it.
  • Tree Roots: Tree roots can encroach on a home's foundation through cracks, and may apply force that leads to your foundation cracking, pipes rupturing, and overall structural deterioration.

How to Choose the Best Foundation Repair Company

Your home's integrity depends greatly on its foundation. It's vital to select the top professionals possible. Focus your research on these attributes:

Licensing and Experience

Washington foundation repair companies can be either general or specialty contractors. Look for companies with a concrete certification, showing that they follow best practices in the foundation field. Talk to staff to gain additional insight into a company's experience. You should ask about local inspection processes, permit ordinances and building codes.

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

Customer Reviews

Before choosing a company, review its online profile with the Better Business Bureau (BBB). You can examine both complaints and positive reviews. Complaints don't mean a contractor is bad news. BBB reviews show how the company handled complaints. It's a good sign if the company has resolved issues appropriately and proactively. You should stay away from a company with more negative reviews, no certifications, and no communication regarding issues.

Foundation Repair Cost in Kent

The price of foundation repair can differ quite significantly depending on the scale of the issues and what's required to resolve them. For minor foundation cracking and settling problems, you may pay as little as $1,800. However, if there is substantial deterioration, the normal cost lands at about $3,000. More complex projects involving tunneling, helical piers, or major mudjacking could cost upwards of $6,900. Below are the average foundation repair costs for common issues.

Frequently Asked Questions About Foundation Repair in Kent

What will I pay to repair my foundation in Kent?

Foundation repair costs about $3,000 in Kent. The final numbers hinge on what type of repair you need and how severe the damage is.

When do I need to waterproof my foundation?

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

You can take several preventive measures to minimize foundation issues:
  • Make sure your home's gutters and downspouts are in good condition and direct water away from your foundation to prevent water accumulation.
  • Water the soil around your foundation consistently, especially during dry spells, to prevent expansion and shrinking.
  • If possible, grade the soil around your home to slope away from your foundation, encouraging water drainage and minimizing the risk of foundation issues.
  • Check your foundation for cracks, and repair any issues promptly.

Are there telltale signs I should avoid a particular foundation company?

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