  • What To Ask References
    Questions for References of Santa Clara County Masonry Contractors

    It's best to choose a Diamond Certified mason because all certified companies have passed an in-depth ratings process that most other companies can't pass. If you want quality from a mason in Santa Clara County, 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 mason 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 mason.

    Keep in mind, though, that references provided to you by the mason 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.

    • Was your property left clean and tidy after the project was complete?
    • Were you satisfied with the work the masonry firm performed? Why or why not?
    • Were the people who did the job subcontractors or employees of the masonry firm?
    • What materials did you use for your project? Did the mason supply them or did you source separately?
    • Did the masonry firm offer good suggestions for materials and designs?
    • Did the masonry firm come punctually on workdays and work consistently?
    • Were there delays in the work or problems getting materials?
    • Would you work with this masonry firm again?
    • What did you have your mason do? (Fix a chimney, install a retaining wall, install a pool, add an outdoor kitchen?)
    • Was the masonry firm able to understand your design sense and execute what you had planned?

  • How To Work With
    Choosing the Right Masonry Firm in Santa Clara County

    Hiring your Santa Clara County mason doesn’t have to result in panic, if you take a few sensible precautions. Look for a masonry firm that provides estimates when promised. Look for a firm with courteous responses to your questions. Dig into the firm’s experience, finding out what kind of masonry apprenticeship and training the employees have.

A physical address is one small guarantee that the firm has a real presence in the community. It’s also a way to contact the mason if all else fails. Look for companies that match your expectations when it comes to the design process. You may want to control the design or you may be open to design suggestions. Either way, you want someone you can talk to so that they can take your aesthetic on board.
    Once You’ve Chosen Your Santa Clara County Mason
    Communication is critical to the success of your project. You need the mason to understand what you want. You are not only repairing or adding a feature to your house, you are sustaining or creating a sense of style. Show the masonry firm any designs or plans you have drawn up for your project. Ask to see any plans and designs they develop. Be sure to ask any questions when you need to. Ask about materials and when they are expected for delivery. Ask for an estimated completion date along with some milestones that you can check on to be sure the project is on track.

Check The Work
Checking Your Santa Clara County Mason's Work Against the Invoice

Your written estimate should guide you through the project, and the invoice should allow you to double-check the project. You should check that your estimate covers all potential categories of charges these may include materials as well as time charges and possibly charges by number of workers. Ask for estimates and invoices that outline each charge individually. A lump sum is not useful to you, since it is not clear what it covers. Verify that the materials you paid for have been delivered. Verify that the materials have been used and the structure built as planned. If you had a working feature built, such as an outdoor fireplace or kitchen, test that it works properly before signing off on the job.

Frequently Asked Questions
FAQ for Masonry Contractors

Q: Why choose a Diamond Certified Mason?
A: Diamond Certified helps you choose a mason with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only masons 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 mason.

Q: Do I always need a mason to do masonry work?
A: There are occasions when the masonry work is part of a larger project. For example, you may hire a landscaping firm to landscape your property. Part of the landscaping includes building a retaining wall using bricks. This wall would normally be built by someone holding a mason’s license. However, since the wall is part of the landscaping project, a person holding a landscaping license is allowed to build the wall.

Q: Why should I choose masonry construction?
A: Structures and buildings made from masonry construction units are safe and long-lasting. They require little maintenance over the long term. When built with a cavity wall, the construction itself offers a fire barrier. Water is also kept out because the protection of a properly built cavity wall diverts water from the inside of the building. Cavity walls offer better energy efficiency than other types of walls.

Q: Is masonry construction safe in California?

A: Modern masonry construction is safe, even in earthquakes. It’s true that unreinforced masonry buildings fare poorly in earthquakes. However, they have been against code since early in the twentieth century. It’s true that it took many, many years for existing buildings to be reinforced to code. However, modern techniques usually employ steel to reinforce masonry construction, and these buildings are safe against earthquakes. Your masonry firm should be able to help you understand how their plans and designs meet code requirements.

Q: Can masonry be repaired?
A: Masonry repairs are very, very common. Chimney repairs are very common, especially in places where brick chimneys still exist. A skilled mason can often match brick color and dye grout so that the repair is less apparent. A typical technique is to make the grout just a shade darker than the existing grout, since the grout will lighten as it dries.

Q: Can masonry be cleaned?
A: It is possible to clean masonry. Some firms specialize in removing old advertising, for example, from the side or front of masonry construction. You do have to be careful, though, since cleaning the masonry often entails spraying with high-powered hoses and chemicals. You should check that the chemicals being used are designed to be used for such cleaning. You should take reasonable precautions so that you, family members, and pets are not around when the chemicals are.

Q: What is interlocking concrete?
A: Interlocking concrete, also called interlocking pavers, refer to blocks that are used to create driveways, pathways, and the like. The blocks are designed so that they allow water to pass through, so that water does not build up on the surface but instead drains into the ground. Interlocking concrete can also be used for commercial and industrial applications – for example, parking lots and roads. Interlocking concrete is fairly simple to install. You need to create a flat base, which might include a weed barrier topped by sand. After making sure the base is compacted, you lay the pavers on top. You also need to install an edging so that the pavers do not move too far out of place. The pavers may have a small amount of movement – for example, if a car drives over them they may flex, but the edging should keep them in place.

The concrete pavers are unlikely to crack, but they can be replaced in part instead of all at once, if something does happen to a section of them. You can choose to seal concrete pavers, but it is not necessary. They come in a wide variety of colors and patterns.

Concrete pavers have a long lifespan, require very little maintenance, and they are better suited to applications where the underlying grade is not flat.

Q: Do masons always need to use mortar?
A: Probably the stereotypical image of the mason is the mortar being slapped on the brick, then the brick being slapped in the wall. In fact, applying mortar correctly so that the building is sound is an important part of the mason’s technique and training.

However, the mason will not always use mortar. In fact, a skillful mason can build one type of retaining wall that uses no mortar at all. In fact, the wall’s strength comes from its mass and the interlocking nature of the masonry construction units employed to build it.

Q: Do I need a permit to have masonry work done?
A: Whether or not you need a permit depends on the type of work you are having done and where you live. You can check with your local planning office. Your mason may be able to help with answering this question based on previous projects completed in your area. Some firms can help with the permitting process, while others expect you to obtain the permit before you call them.

Q: Is masonry work the same as tile work?
A: In fact, the state of California issues two different licenses for masonry and tiling. The masonry license (C29) specifically excludes tiling, while the tile license (C54) is for preparing surfaces and installing ceramic and/or mosaic tile on those surfaces.
