Know What You Want
Ask Yourself the Right Questions

Before you begin calling Sonoma County tile contractors in your area, there are a few things to ask yourself.

First of all, what is your deciding factor? Is it important to you to have a Diamond Certified tile contractor whose work is backed by the Diamond Certified Performance Guarantee? Are you in a hurry to get the job finished by a certain date? How much of a role does price play in your decision?

It is important to have a general idea of what you plan to spend when you begin a project. A quality tile contractor will be clear about price before they ever begin work. Do you know what your budget is for this project?

Remember, if you are remodeling a whole room, (a bathroom, for example) the tile you choose is a very important part, but just a piece of the puzzle. If you need to add cabinets, or a new bathtub, etc, that would be a separate part of your budget.

As long as you have a general idea what you want to spend, a professional tile contractor can help you find a plan that works for you.

Some specific questions you may want to ask yourself include these:

  • Do I want a Diamond Certified tile company that is rated best in quality and backed by the Diamond Certified Performance Guarantee?
  • In which rooms or areas do I want tile installed?
  • When do I want this project started and completed?
  • Are there any specific types of tile or tile colors or features I want?
  • What is my budget for new tile installation services?

What To Ask In Person
Interview Local Tile Setters in Person

If things went well in your phone conversation, you can choose to have the tile contractor visit your property to see the project firsthand.

No tile laying contractor can give you an accurate bid without checking out the project in detail. That’s why many tile contractors provide this service free of charge.

Some questions to ask in person include these:

  • Who will be doing the doing the new tile installation? You, employees, or subcontractors?
  • How many people would be visiting my property during the tile installation?
  • What process do you use to select and train employees? 
  • Should I be present during the tile laying project or can I leave the property in your care?
  • How long can I expect this tile installation to last? What start and finish dates can you propose?
  • How long does a tiling project like this one usually take you?
  • Particularly if you live in a small community like Agua Caliente, Cazadero, Bloomfield, Camp Meeker, El Verano, Forestville, Monte Rio, Lytton, Roseland, Stewart’s Point Rancheria or Vineburg, you’ll want to ask: Will you charge extra fees for traveling to my location?
  • What kind of mess can I expect during the process, and where on my property can I expect it?
  • Will I be able to live in my home while you are completing the project?
  • Now that you have seen my property and heard about my plans, what suggestions do you have for me?
  • Does your price estimate include materials or do I pay for those separately?
  • How sure are you of the quoted price? Have you factored in for extra time or broken tiles, etc?
  • When can you start this tile setting job?

    Of course each person has different needs, so take all opinions with a grain of salt – but you might uncover a red flag, or a hidden jewel of data that helps you make that final decision.

    • Did the company complete the work within the timeline that they originally told you?

  • How To Work With
    Benefit From Your Contract With Sonoma County Tile Companies

    During any tile installation process, it is important to work with your tile contractor as your partner. The tile contractor needs your input, and you need their expertise. Be very clear about your vision for the project.

    If you are having a countertop installed, be sure to discuss whether you want a tile backsplash installed as well, and what kind of detail you’ve imagined for the finished project. If a certain type of specialty tile, like Italian tile or pebble tile interests you, let your contractor know right away. They can discuss with you the pro’s and con’s of each type of tile in your particular environment.

    Collect samples to show your Sonoma County tiling contractors – be they magazine photos, or sample tiles from your local hardware store.

    Certain types of embellishments could be difficult to install, so discuss that all before the project gets underway.

    You may also ask if your chosen tile contractor typically works with, or recommends a specific brand of tile. Do they recommend Thompson tile, Marazzi tile, Riello Ceramic tile, Armstrong tile, Serenissima Group tile or some other product line?

    Once you know what kind of tile you’ll be working with, you should confirm the state of the property before the tile installation begins. Ask your tile contractor if they will do demolition of the existing area, of if you need to handle that another way.

    Also, will the tile contractor complete the basics like installing drywall, greenboard or hardybacker in the space before they begin placing tile? Or will you need to hire another company to do these parts of the job?

    Know what to expect of each other so you can enter the agreement with a clear plan. This will help avoid disagreements or misunderstandings, and you’re more likely to be happy with the outcome.

Popular Tile Services in Sonoma County

Tile Backsplash Installation
A backsplash is an area of tile about a sink or countertop that lines the wall to protect that vulnerable area from splashing liquids or other matter. Apart from adding a very practical benefit, a quality tile backsplash can provide an amazing transformation to the look and feel of your room. The huge variety of tile patterns and textures is nearly unlimited. Mosiac tiles and specialty designs are often used in backsplash designs. In particular the spaces above a kitchen stove, sink or bathtub are wonderful areas to feature an artful tile design. Ask your Sonoma County tile installers for suggestions to add a special touch to your room.

Glass Tile
Glass tiles can be large or small, tinted, opaque, iridescent, smooth or rough. Some glass tiles available from Sonoma County tile setters are even formed from recycled glass. Glass tile provides an unmistakeable and unique look with depth. Glass tile can add something special to your design, be it a tile walkway, a special border accent, a backsplash, an entire room, or a tiled swimming pool.

Tile designs incorporate the ambience you choose for your area by utilizing the perfect combination of color, texture, placement and artistry.

A tiled shower enclosure is the way to go. Tile is durable and water proof, but in addition allows you to choose a distinguished look for this important space. Tile in the bathroom can include floors, countertops, room dividers, walls, shower walls or any other surface. Local tile contractors who care about customer satisfaction will help you choose shower floor tiles with an appropriate amount of grip to prevent falls. They can also build in custom shelves, grips, soapdishes, etc. to suit your needs

Subway Tile
There are very basic, creative ways to use simple subway tiles to complete your signature effect. Subway tiles are the traditional white, glazed ceramic tiles found on the walls of New York City subway stations in the early 1900s. Most are three inches by six inches, and laid in an offsetting pattern. However, almost any rectangular tile can be referred to as Subway Tile.

Granite Tile
Beautiful granite tile is always a high class option for your home or office. The distinct look and classy polished feel of granite set your space a step above the rest. Many opt for granite in high-impact areas like entryways, showcase rooms, and open kitchens. You’ll definitely want a qualified contractor to complete your granite work, and give this luxury-worthy substance the quality setting and careful design that it deserves.

Tile Kitchen
Installing tile in your kitchen is an obvious choice. What better surface to beautify your home while protecting surfaces from the wear and tear of a moist environment with fluctuating temperatures? Quality tile will repel moisture, keeping spills easy to clean, as well as protecting from steam condensation. Classic tile installations for Sonoma County kitchens includes tile floors, tile counters, tile backsplash, and tiled kitchen islands. Tile is the perfect solution, easily personalized for any kitchen environment.

Outdoor Tile
Tile is also a great medium for outdoor landscaping projects. Beautiful Sonoma County has many gorgeous examples of using tile to beautify an outdoor space, and increase its utility. Tile walkways, stepping stones, trails, bench blocks, fountains, pools, and patios are all excellent examples of how tile can create something wonderful outside.

Tile Countertop
Tile provides an affordable, durable hard surface for kitchen, bathroom or workroom countertops. It is also easily molded into the perfect shape for irregular islands or specialty additions. Use a diamond certified tile contractor to help you create a totally unique look that works perfectly.

Tile Flooring
Tile floors are long-lasting, attractive and easy to clean. It is no wonder that tile flooring is one of the top requested tile installation projects. Tile is especially popular for hallways, entryways, bathroom and kitchen floors. When choosing tile for flooring you’ll need to consider how much traffic might pass through that area. Porcelain and ceramic tile manufacturers rate tile from Class 1 to Class 5 for durability. Class five is the most resilient tile. Natural stone tiles do not come with this rating system.

Another factor to consider with flooring is how slippery it might be – particularly in areas with lots of moisture. In general, it is best to choose a matte tile over glossy for flooring in bathrooms, kitchen and entryways. However, ultra-smooth tiles such as marble are often chosen for flooring despite the danger of slipping. Your Sonoma County tile contractor can assist you with such decisions if you like.

Frequently Asked Questions
FAQ for Tile Contractors and Tile Installers

Q: Why should I choose a Diamond Certified tile contractor?
A: Diamond Certified tile contractors are backed by the Diamond Certified Performance Guarantee. Only local tile contractors who have proved their quality work and superior customer service through an in-depth rating process earn Diamond Certified.

Q: What rights do I have as a customer of a Diamond Certified tile contractor?
A: Customers of Diamond Certified tile contractors have the right to receive a written estimate of services before the project begins. The Diamond Certified Performance Guarantee ensures that all aspects of the original contract be met, as well as complete customer satisfaction. The work is already done for you to hand pick the best of the best contractors who have a well deserved reputation for excellence and customer service. If anything goes awry, American Ratings Corporation is there to back up the work to your satisfaction.

Q: Is it really important to choose a certified contractor to complete my tile project?
A: Tile installation is a labor intensive process. Once it is completed, it is a semi-permanent renovation that will add value to your home or property. Fixing a bad tile job usually requires everything to be torn out and completely redone. So you want your tile work done right the first time. Hiring an unlicensed contractor, or an unknown tile guy means you have no legal way to ensure that any mistakes will be remedied should they occur. It could be an expensive lesson.

Q: How long will it take to complete my tile installation?
A: The time it takes to complete your tile installation project depends upon several factors including the size of the area to tile, if it is ready to begin working, and what kind of materials and designs you will include. Adding decorative designs or special features will take longer than just covering the surface with a single color tile. In general, tile jobs take from a couple days to a couple of weeks depending on the scope of work and availability of the contractor’s crew. Be sure to ask your tile company representative for an estimate of work completion before they begin. You can request to make this timeline part of your written contract.

Q: How will tiling my property affect the value of my property?
A: A quality tile job can make a huge positive difference in the value of your home on the resale market. Home buyers notoriously prefer upgraded kitchens in particular. A special feature like a beautiful fountain in a tiled patio, artfully tiled pool area, or a uniquely tiled bathroom may be just the feature that captures the heart, and the pocketbook of your buyer. Tile is more durable, and more customizable than many other common surface covers like linoleum, vinyl or formica. Tile installation is as much an art as a trade. The right artist can work a miracle in your home.
