What To Ask In Person
Learn from Previous Countertop Installation Customers in Marin County

Previous customers can offer a wealth of information about the kind of work you’ll get from a kitchen counter contractor before you even sign a contract.

All Diamond Certified companies are rated on the basis of independent research and carefully conducted consumer surveys that leave little room for doubt about the kind of service you’ll receive. You can read Diamond Certified reports on all certified companies, including verbatim survey responses.

Previous customers can offer a wealth of information about the kind of work you’ll get from a kitchen counter contractor before you even sign a contract.

All Diamond Certified companies are rated on the basis of independent research and carefully conducted consumer surveys that leave little room for doubt about the kind of service you’ll receive. You can read Diamond Certified reports on all certified companies, including verbatim survey responses.

And best of all, you’ll never have to worry about dubious ratings or fabricated reviews, because Diamond Certified research is conducted using telephone interviews of a large, random sample of actual customers.

If there aren’t any Diamond Certified countertop contractors near you, you can still collect references from the contractors you contact. Taking a little time to survey previous customers on their experience with a contractor removes much of the guesswork involved in selecting the contractor that’s right for you.

Keep in mind, though, that references provided to you by the countertop contractors themselves 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. Contractors will often give you a few customers to call that they know are satisfied.

Request a list of the contractor’s five most recent customers and contact them with questions about their experience with the contractor and satisfaction with the finished product. Some relevant questions include:

  • What was the nature of your countertop project?
  • Was the work completed in a timely manner?
  • Were you satisfied with the quality of the work you received?
  • Did you encounter unanticipated costs or contractual disagreements?
  • Did you feel you received a fair price?
  • Why did you choose to work with this specific countertop contractor?
  • What were you most pleased or displeased with?
  • Would you hire this countertop contractor for another project?
  • Were you pleased with the material and features you chose? Is there anything you wish you’d have done differently?

  • How To Work With
    Signing a Contract for Countertop Replacement Services in Marin County

    Once you’ve decided which contractor best suits your needs, the last step before work begins is to negotiate and sign a contract. A contract is a legal agreement that outlines and protects the interests of both parties.

    This essential step will ensure that both parties are clear about what a job will entail in costs, payments, and timeframe. Your contract should detail how and when the work will be done, which materials are necessary, and how much each material costs. A good contract can spare you the headache of legal action down the line.

    Start your contract by making a list of all responsibilities of both parties. For example, is the contractor responsible for purchasing and transporting materials? Who is going to obtain the permits, if necessary? Next, determine an agreed upon price for all the involved materials and labor. This is where you can use your preliminary pricing research.

    The list may include items such as refinishing materials, tile, grout, and adhesives. If you found materials cheaper, tell your contractor where.

    Also, don’t be afraid to bring up estimates that other contractors provided you, if they are lower than the contractor you’ve selected. This can help in negotiating a better price for your countertop remodel. Finally, review the estimate your chosen countertop contractor has provided and recommend any changes. Be sure to include a clause dictating that you wish to approve any costs above the agreed-upon amount.

    Finally, a guarantee of the quality of the work and all warranty time periods should be specifically noted. Once you have agreed upon a cost that fits your budget, a timeline in which the work is to be completed, and a schedule for submitting payments, your countertop contractor can begin your remodel.

    Obtain and Compare Free Written Estimates of All Costs Involved in Your Project
    After you have discussed the nature of your specific project in detail with prospective licensed Marin County countertop contractors, you should obtain a complete, written estimate of charges for all labor and itemized costs of all materials involved.

    A countertop project can call for additional items besides the actual surface material. Be sure to also get an estimate of labor hours for each phase of the project along with the cost per hour.

Top 10 Requests
Common Requests for New Countertops in Marin County

Countertop contractors in Marin County can often perform a wide range of tasks, but some countertop remodel projects are more commonly requested than others.

The most requested Marin County countertop remodel services include:

Granite and marble sealing
Natural stone countertops are exquisitely beautiful, but also require regular maintenance to maintain their natural beauty. For this reason, properly resealing a granite or marble countertop is a common task for qualified countertop contractors. Penetrating or topical sealers will protect these porous surfaces, preventing liquids from discoloring and saturating the stone, which weakens it.

Scratched countertop repair
Scratches can occur when any sharp objects his drive across the surface of the countertop. Given the volume of use and abuse that countertops sustain, scratch repair is understandably a common task for countertop contractors. Stone scratches will appear white, making them more visible on darker stone surfaces. Your contractor can remove surface scratches by refinishing the stone surface material using coarse abrasives.

Etched countertop repair
Etching occurs when acidic liquids, such as coffee or lemon juice, create create a dull spot or ring on the surface of natural stone countertops. Calcium rich stones like marble and limestone are the most susceptible to etching, and the solution is refinishing and polishing the surface. Your licensed countertop contractor will be able to restore countertop to its natural luster.

Crack and broken edge repair
Most countertops are built to withstand a tremendous amount of weight and force. However, over time, and especially without regular maintenance, even hardy stone surfaces can crack or break. Typically, such problems are preventable, but if your countertop does crack or break, you need not replace it entirely. broken edges can be pared down and reshaped. Cracks can be repaired by filling with an adhesive, and then matching the color. This may also require refinishing. Qualified countertop contractors can also repair brakes and cracks that occur beneath the surface.

Dullness repair
All stone countertops dull over time and extensive use. Exposure to abrasives and acids rapidly accelerates the aging process. Your countertop contractor however can refinish and polish the surface back to its natural sheen.

New kitchen countertop installation
Replacing existing kitchen countertops with brand-new surface materials is not a job for the faint of heart. It's a job for a highly skilled countertop contractor. Each material has its own unique properties and quirks, so it is of vital importance to find a contractor with extensive experience installing the material you've selected, whether it is laminate, natural stone, stainless steel, or solid surface.

Kitchen countertop expansion
Another common countertop remodel project involves expanding the existing countertop or reconfiguring the kitchen space. Two little kitchen counter space is one of the most common complaints homeowners have about their kitchens. A countertop contractor can help you rethink your kitchen space to maximize the utility you get from it. Common methods include installing an island, and long getting an existing surface, and moving or repurposing an existing surface.

Concrete countertop design and installation
Concrete countertops have gained considerable popularity in recent kitchen design. With concrete countertops, artisans can create unique, specially detailed designs, and as such, concrete countertops are typically more expensive than common surfaces like granite or marble. They are also rather high maintenance, and need to be sealed regularly to prevent staining. However, their unique designs also have greater longevity and can increase resale value.

Bathroom and office countertop installation
Not all countertop remodel projects are confined to the kitchen. While they don't typically experience the wear and tear of heavily used kitchen surfaces, bathroom and office countertops need to be replaced from time to time, both for functional and aesthetic reasons. A qualified bathroom and office specialist can help you size and match the proper surface to your existing bathroom and office design.

Tile countertop installation and repair
Tile countertops represent a large enough subset of all countertops that they merit their own category. Many contractors specialize exclusively in tile work and repair. Whether it's replacing broken tiles or designing an elaborate, colorful countertop backsplash, tile countertop specialists can work wonders with your existing tile countertop or replace your current countertop with a richly designed, durable, and economical new tile countertop.

FAQ for Countertop Companies and Kitchen Counter Installers

Q: Why choose a Diamond Certified countertop contractor?
A: Diamond Certified helps you choose a countertop contractor with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only countertop remodel contractors rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified countertop contractor.

Q: How long does a typical countertop remodel take?
A: This depends on the nature of your project. A simple refinish should only take one day. However, installing brand new fixtures or custom fixtures, changing the floor plan, or changing the style of your countertop fixture all dramatically increase the timeline. Selecting materials and finalizing terms can take 2 to 3 weeks, ordering and delivering materials can take 3 to 6 weeks, removing old materials can take 2 to 3 days, installing new materials can take 1 to 3 weeks, and finishing touches and clean up can take an extra week.

Q: Will my countertop contractor be able to help me choose materials and obtain permits, if necessary?
A: Qualified, licensed countertop contractors will definitely offer creative and technical expertise in the decision-making process, steering you clear of materials that may not fit your budget or size-constraints, and lending their advice on various materials and manufacturers they’ve worked with. They will also most likely have a portfolio of design options you can peruse, and will know the ins and outs of obtaining building permits.

Q: Which materials have the best stain resistance, heat resistance, scratch resistance, and crack resistance?
A: Any surface described as nonporous, such as stainless steel, laminate, solid surfacing, and ceramic tile will be stain resistant and easy to clean. Surface materials that require regular sealing, such as granite, marble, and solid surface, can also scratch easily. Stone, tile, and steel surfaces are the best for heat resistance.

Q: What are the most common countertop materials?
A: Engineered stone, granite, marble, slate, stainless steel, concrete, solid surface, ceramic tile, and laminate are the standard countertop surface materials.

Q: How expensive is a new countertop?
A: New countertops vary widely depending on the surface material used, and the size of the countertop. Expect most high quality materials to cost between $50 and $200 per square foot, with the exception of laminate and rule, which are typically under $50 per square foot. Add to this additional materials such as grout and the cost of actual installation, typically $40-50 per hour. The number of hours required once again depends upon the size of the job.

Q: What is a typical payment schedule?
A: Most contracting firms will require 30-50% up front at the time the contract is signed, an additional 30-40% upon delivery of the materials, and the balance upon completion.

Q: What information do I need about my sink before selecting and ordering a countertop material?
A: You should know the kind of material your sink is made of (stainless steel, porcelain, acrylic), the size of the sink, the style of sink (undermount, integrated, drop-in), and the number of bowls in the sink.

Q: I don’t know much about interior design—can a countertop contractor help me find something that looks good?
A: Many larger contractors have a designer and interior decorator on staff who can help you select fixtures that will be an attractive fit for the rest of your kitchen or bathroom, or provide a optimal first step in a complete kitchen or bathroom overhaul in the future.

Q: What is a typical warranty for countertop fixtures and contracting remodel services?
A: Many contractors will guarantee their work for one to five years after completion of a countertop remodel, depending on the type of work. Countertop manufacturers typically offer a 10-20 year guarantee against defects.
