Things to Consider About a San Francisco Foundation Contractor
When you are searching for a foundation contractor in San Francisco, including the larger Districts of Excelsior, Pacific Heights, Nob Hill, North Beach and Bayview, check to see if they have already done a foundation similar to the one you are having repaired or are considering having built. If so, it will be rather easy for them to modify the plan. They will also understand what types of permits are needed and have ideas of what could improve your foundation.

Be sure to check the references your foundation contractor gives you. Request two positive references as well as a reference that may not be so positive. Ask if there are any foundations that they have done that you might be able to see. You want to be sure that this person is someone that you can see yourself working with for a period of time and getting along with happily.

Be sure to check several potential foundation contractors for your project. Give identical copies of your detailed plans to each potential candidate for a quote. You should get at least three different quotes before making your final selection. Also, make sure the quote includes materials that meet your project specifications. Because a foundation contractor will save you time, money and stress, be sure to do your homework and find a quality company to do business with. This way you will have done everything possible to have a safe and solid foundation.

You do not want to hire a foundation contractor who does any of these things:

  • Applies pressure for you to hire them without allowing you any time
  • Has no business number in the local telephone directory
  • Requires a large down payment saying that it is for the purpose of purchasing materials
  • Gives you only a post office box address rather than a physical address
  • Suggests who you should borrow money from for your project and this is someone the contractor knows
  • Requests you pay for everything upfront before the project has even begun
  • Offers discounts or rewards for you finding customers for them
  • Requires YOU to obtain any required permits
  • Insists you pay in cash
  • Quotes an actual price without even seeing the job
  • Offers only lifetime warranties (lifetime warranties are only as good as the life of the company - when the company closes, so do the lifetime warranties!)
  • Wants to use leftover materials from another job for your project
  • Offers a discount if you will sign a contract on-the-spot

If you want quality from a foundation contractor in San Francisco and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you'll never be fooled by fake reviews. That's because all research is performed in live telephone interviews of actual customers.

If you can't find a Diamond Certified foundation contractor within reach, you'll have to do some research on your own. If you do, it's wise to call some references provided by your foundation contractor. Keep in mind, though, that references provided to you by the foundation contractor are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That's because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

If you do call references on your own, specifically ask for a list of the company's 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

  • Were you satisfied with the service from the foundation contractor?
  • Were there any unexpected costs? If so, what where they?
  • Did the foundation contractor keep you up to date on the status of your project?
  • If you live in a smaller town such as Golden Gate Park, The Haight, Haight-Ashbury and Hayes Valley, did you have to pay extra for their travel expenses to your home?
  • Did the foundation contractor show up on time?
  • If you need a foundation contractor in the future, will you consider hiring this foundation contractor?
  • What type of foundation project did you hire the foundation contractor to complete?
  • Would you recommend this foundation contractor to your family and friends?
  • Did they finish the job on time?
  • Did the foundation contractor clean up after completing the job?
  • Do you feel like the foundation contractor charged a fair price for the quality of the work?
  • Did the contractor seem receptive to your input?
  • Did the foundation contractor provide answers to questions to your satisfaction?

After you have found a San Francisco foundation contractor that you can trust, you will have peace of mind as you get ready for your foundation work. Once you've hired a foundation contractor in San Francisco, you will have an initial meeting between you and the contractor to discuss your requirements for your foundation work and the contractor's qualifications. An estimate of the project and its feasibility is drawn out. Furthermore, you will discuss the budget and design of the foundation project as well as any restrictions and permits that will be needed.

Use the notes that you have taken so you can accurately describe any concerns that you have. Be very detailed and don't be in a rush. It is as important for you to hear their suggestions and observations as it is for them to hear you. If you don't understand something, ask questions. Your foundation contractor should be able to explain the foundation work so that you understand the process of what the job entails.

The estimate should include an itemized list of the cost of supplies and the labor. Be sure to get all estimates in writing before any work begins. Don't ever sign a blank estimate.

It is important for you to completely comprehend the foundation project and what it entails. The contractor will provide you with an estimate based on the specifications. He will also offer choices. Once the final contract has been drawn, the next step will be applying for permits. Last of all, the construction and financing process will begin.

Getting the Most Benefit from Your San Francisco Foundation Contractor's Contract
When you feel satisfied with the information you have received from your San Francisco foundation contractor, you are ready to sign the contract. Be sure that they have a phone number where you can be reached at all times. Once the contract is drawn up, it should be signed by both parties: you and the foundation contractor. If any sub-contractors will be involved, they should sign the contract as well. The contract should protect the interests of both you and the contractor. Expect the foundation contractor to stay within the estimate. However, if the actual cost exceeds the original amount of the estimate, they must get your approval before moving ahead.

You contract should include the following:

  • A clear, concise, and complete description of the project, including start and completion dates. It should also include who will be responsible for each aspect of the project.
  • Warranties should be written and the length of time as well as limitations should be covered. Warranties should cover materials and workmanship, and names and addresses of the warrantor. This may include the contractor, manufacturer, and distributor.
  • How "change orders" will be handled. Any changes or additions to the project should be written up in the contract so that the conditions for change are pre-determined.
  • Furthermore, the contract should list how and when payment will be made for adjustments.
  • Contractor's name, physical address, mailing address and phone.
  • The estimate or quote of the project.
  • Who will be responsible for obtaining necessary permits (this is usually the contractor).
  • Detailed materials list: product, size, color, type, model, and brand name. Any additional or alternate materials that may be used if necessary should also be listed.
  • A payment schedule as well as the terms for the contractor, subcontractor(s) and suppliers.
  • Any oral or verbal promises the foundation contractor made.

Prep Work for Your San Francisco Foundation Contractor
Professional foundation contractors are able to handle the very small to very large aspects of their work. However, depending on if you are having a brand new project or having foundation repair there are some things that you can do to prepare for them and to make their progress in your foundation work go more smoothly. Doing these things may even cut down on their labor costs and can keep your home and belongings from being damaged.

Provide parking space and room for their work vehicles to maneuver. Foundation contractors have large vehicles that require more space than average. Contact your contractor before they begin building and ask them how many parking spaces they need and how much room they need for oversized vehicles. It is also helpful to walk through the area with your contractor so any hazards or clearance issues can be pointed out before the actual work begins.

Keep your pets and children away from the area. Your foundation contractor will be focused on your project and should not have to watch out for your pets or children at any time. This not only prevents accidents and injury but also any expense that comes from accidents that may happen because of children and pets being in the way.

Trim plants and bushes that are in the way of your foundation area. You can save money and time by preparing the area for building by trimming or removing any plants, trees or bushes that are in the way. Ask your contractor what they recommend and the amount of space they require.

Remove any furniture or movable items from the area. Before they begin work on your foundation job, remove all of the objects that may be in the way such as barbecues or lawn chairs.
