Foundation Repair Cost in Mill Valley


There are several types of foundation repairs. Exactly which one that is needed might change based on exactly what issue you're dealing with.

Not all companies that do basement repairs also do waterproofing, but this project is often necessary and can go a long way towards mitigating future problems. A waterproofing contractor will identify the source of the issue and come up with possible ways to fix it. Simple solutions could involve rerouting a gutter system, while more involved solutions could necessitate waterproofing your entire basement or foundation. Interior waterproofing can include the use of devices like sump pumps or drains. Exterior waterproofing tends to cost more but be more effective, and may involve things such as landscape work or rubber foundation coating. The final price is highly variable based on the type of work done and the size of your basement or foundation. Foundation or basement waterproofing in Mill Valley can range in the thousands of dollars, possibly over $10,000 if extensive repairs are needed.

Other kinds of foundation repair include:

  • Leak Repair: Leaks are often a symptom of a bigger problem, and your Mill Valley foundation repair company might recommend waterproofing along with fixing the leak. The cost of this repair will be highly variable depending on precisely what is needed.
  • Piering / Underpinning / Leveling: Leveling a foundation can be expensive, but is often worth it when it comes to avoiding more issues. Piering or underpinning involves installing additional supports (normally concrete pillars, or piers) under the foundation to level and support it. It may cost several thousand dollars per pillar.
  • Crack Repair: The size of the crack in your foundation will determine how much it costs to fix it — most foundation crack repairs cost a few hundred dollars. Your foundation repair company will likely fill small cracks with epoxy or polyurethane foam and larger ones with concrete.
  • Stabilization: Your foundation repair expert can repair bowing walls using reinforcements made of steel or carbon fiber. These stabilizing strips usually will run you a few hundred dollars each. The total price will depend on the type and number of strips used.

Signs Your Foundation is in Need of Repair


While a professional inspection is highly recommended to diagnose foundation problems, some symptoms you may notice on your own. Call your local Mill Valley foundation repair company if you notice any of the following:

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

Choosing a Mill Valley Foundation Repair Company


Some specific factors can give you an idea as to whether you've found a reputable Mill Valley foundation repair company. Some of these include:

  • Licensing and Insurance: Your Mill Valley foundation repair company should be able to show proof of general liability insurance before you sign a contract. You might also look to verify whether the company meets the general contractor licensing requirements for California.
  • Inspection and Estimate Process: A free inspection and estimate should happen at the start of the foundation repair process, no matter what company you choose. Your local experts should be able to tell you what kind of repairs will be needed and how much you might expect to pay.
  • Cost: You should ask for cost estimates from a couple of companies for comparison. Beware of companies with very high or very low estimates, and keep an eye out for things like travel fees if their technicians would have to drive a long distance to get to you.
  • Partnerships With Structural Engineers: If your foundation repair company doesn't have a contract with a structural engineer, you can reach out to one yourself. For a fee, a structural engineer will confirm your foundation repair company's assessment of your foundation problem and tell you if the proposed repairs are sufficient.
  • Warranties: You should make sure to employ a foundation repair company that provides warranties for its work. Depending on the company (and maybe even depending on your location in California) the time period and other specifics may vary.

Your foundation is a critical part of your home, and it can affect many other things about it. For this reason, you only want one of Mill Valley's top foundation repair experts to work on it. By choosing from our list, you'll make sure your home is in safe and trustworthy hands.

FAQ's for Foundation Repair in Mill Valley


What are some ways I can protect my house's foundation?

If you are building a new house or an extension on an existing house, you can get a soil report before building. This report will let you know whether the soil in a particular area can support a structure without leading to shifting or sinking. For your current home, you can hire a structural engineer (typically for a few hundred dollars) to perform an inspection and determine if there are any signs of deterioration or damage to your foundation. And of course, if you become aware of any problems yourself, contact one of your local foundation repair experts in Mill Valley to find out what can be done about it.

If the weather in Mill Valley gets particularly hot and dry, you might need to water your foundation. This helps prevent the soil around it from drying out, crumbling, and increasing the risk of foundation shift. (How often you need to do this in Mill Valley will depend on the weather in recent weeks.) However, make sure to avoid overwatering your foundation, as excess moisture can cause just as many problems as not enough.

Will I be able to remain in my Mill Valley home while foundation repairs are happening?

We suggest going over the details with your Mill Valley foundation repair professional before committing to a contract, but usually the answer is yes. For most foundation repair jobs, you can stay in your home while they are being completed.

How long does foundation repair last?

Foundation repairs undertaken by a reliable company should last a long time. Large repairs, like basement waterproofing, can be very involved and expensive, but they do a lot in terms of reducing the risk of future issues.

I'm planning to purchase a home in Mill Valley. How can I make sure that it won't need extensive foundation repairs?

It is a smart idea, if possible, to get a Mill Valley foundation repair company to inspect a house and give a free estimate of what necessary foundation repairs could cost before you sign anything. You may be able to bring this estimate to price negotiations for the property.
