Foundation Repair Cost in Seattle


There are several subcategories of foundation repairs. Exactly which one you need will change based on the precise issue you're dealing with.

Not every company that does basement repair also does waterproofing, but this project is often necessary and can go a long way towards reducing the risk of future issues. A waterproofing contractor will determine the source of the issue and identify ways to fix it. Simple solutions may involve rerouting a gutter system, while more involved solutions can involve waterproofing your entire basement or foundation. Interior waterproofing involves the use of such devices as sump pumps or drains. Exterior waterproofing tends to be more expensive but more effective, and might involve things such as landscape work or rubber foundation coating. The total cost is highly dependent on the size of your basement or foundation and the type of work that is done. Basement or foundation waterproofing in Seattle can range in the thousands of dollars, possibly over $10,000 if the repairs are extensive.

Other types of foundation repair include:

  • Leak Repair: Your Seattle foundation repair expert might suggest one of several types of solutions to fix leaks and their underlying cause. The total price of repairs will depend on if the problem requires only minor fixes or something more extensive like waterproofing.
  • Piering / Underpinning / Leveling: The process of leveling your foundation can cost more than other types of repairs, but it is often worth it in terms of avoiding future problems. Underpinning or piering involves installing additional supports (typically concrete pillars, or piers) underneath the foundation to level and support it. You may spend several thousand dollars per pier.
  • Stabilization: Your foundation repair expert can stabilize bowing walls by using reinforcements made of steel or carbon fiber. These stabilizers normally will run you a few hundred dollars apiece. The price will depend on the type and number of strips used.
  • Crack Repair: Small foundation cracks can be repaired with polyurethane foam or epoxy, while large cracks may need to be filled with concrete. The bill for this kind of repair is usually in the few hundreds of dollars, depending on the size and number of the cracks.

Signs Your Foundation is in Need of Repair


While a professional inspection is strongly recommended to diagnose foundation problems, certain symptoms you might notice on your own. Some signs that might prompt you to call your local Seattle foundation repair expert for an inspection are:

  • Cracked driveways
  • Uneven basement floors
  • Visibly damaged or crumbling foundation
  • Cracks in foundation walls or flooring
  • Shifted, skewed, or tight doorframes or window frames
  • Walls that lean inwards at the top Water in your basement
Your home in Seattle may need foundation or basement waterproofing, in which case you may notice:
  • Changes in floor height or newly uneven floors
  • Presence of mold or mildew
  • Bowing or buckling walls
  • Damp or musty-smelling basement
  • Visible water in your basement White powder, spots, or other signs of fungus

Choosing a Seattle Foundation Repair Company


Some specific factors can help inform you whether you've selected a reliable Seattle foundation repair company. Some of these are:

  • Licensing and Insurance: Your Seattle foundation repair company should be able to show proof of general liability insurance before you commit to a contract. You may also want to verify if the company meets the general contractor licensing requirements for Washington.
  • Inspection and Estimate Process: A free inspection and estimate should occur at the start of the foundation repair process, no matter what company you choose. Your local experts should inform you what kind of repairs will be needed and how much you should anticipate paying.
  • Cost: It's always smart to get quotes from multiple companies to compare. Be on the lookout for extra fees like travel fees (if the company location is far away) or companies with unusually high or extremely low prices.
  • Partnerships With Structural Engineers: Many foundation repair companies have a contract with a structural engineer — if your company does not, you should seek to establish this relationship on your own. A structural engineer will do their own foundation inspection (for a fee) and make sure that your foundation repair company's inspection was correct. They will also say whether they think that the proposed repairs are appropriate.
  • Warranties: Factors like the weather in your part of Washington may have an effect on the specifics of a warranty, but any reputable foundation repair company should offer one. Be sure to get the details of your company's warranty policy before signing anything.

Your foundation is foundational to your home, and it's critical that you select only the top experts to work on it. Choosing from our list of Seattle's best foundation repair experts guarantees that you'll get someone who is trustworthy and reliable.

FAQ's for Foundation Repair in Seattle


What are some things I can do to protect my house's foundation?

If you're planning on building a new home or an extension on your current home, you can obtain a soil report prior to breaking ground. This report will tell you whether the soil in a certain location can support a structure without leading to sinking or shifting. For your current home, you can hire a structural engineer (typically for a few hundred dollars) to perform an inspection and let you know if there are any signs of deterioration or damage to your foundation. And of course, if you spot any problems yourself, contact one of your local foundation repair experts in Seattle to find out what can be done about it.

If the soil around your Seattle home begins to dry out, you may need to water your foundation. This helps keep the surrounding soil from drying out, crumbling, and possibly shifting your foundation. (You may not actually need to do this too often in Seattle, which can see a good amount of rain.) However, make sure to avoid overwatering, as excess moisture can cause as many problems as not enough.

Can I remain in my Seattle home during foundation repairs?

Usually, yes. Throughout most foundation repairs you'll be allowed to stay at home. Make sure that you check with your Seattle foundation repair company to ensure that you're aware of the important details before you sign a contract.

How long does foundation repair last?

Foundation repairs undertaken by a reliable company should last a long time. Large repairs, such as basement waterproofing, can be rather involved and expensive, but they go a long way towards mitigating the risk of future issues.

How long does it take to do various foundation repair projects?

The amount of time a foundation repair takes will vary greatly depending on the type of repair that is needed and the size of your home. Most repairs will take anywhere from one to several weeks. You should speak with your Seattle foundation repair professional for the specific timeline for your project.
