Granite is a great choice of material for any kitchen design; it is beautiful, durable and functional. Granite Countertops are also an investment, they are a higher priced material that adds to the value of your home and is cut custom to fit your unique layout and design. You need to be wary of the quality of granite you are selecting and how it is going to be installed in your home.
There are three things to consider when looking at quality of granite;
- The slab itself
- Fabrication
- Installation
Granite Slab
The quality of the granite slab can be evaluated by looking for a few telltale signs of a weak slab or a slab that may crack warp or twist over time. Some of these can be hard to identify for the untrained eye. Your builder or designer should be able to help you spot potential, problems. For the most accurate results make sure you are examining the granite under good lighting.
- Look for hairline cracks in the granite this is a definite indication of a weak slab.
- Look for pits every slab has them, a higher quality slab has very little pitting and the pits are smaller, and filled. The methods for filling pits vary as well as quality of filler. Your designer can help you identify a poorly filled pit before you purchase.
- Check thickness throughout the slab measure the thickness of the slab every 8 to 10 inches to gauge variation in thickness, a good slab will have little to no variation in thickness.
- If the slab is already polished try scratching the surface with the edge of a coin if it scratches your dealing with a slab that has been sprayed with a wax polish, this polish is weak and will continue to scratch over the life of the slab.
- Shine, look down the slab at eye level and check for any variances in the level of shine across the material, a good slab will have an even continuous sheen.
Fabrication
- Inspection- the granite is inspected for any unusual condition and the buyer is notified of any potential issues. The issues need to be considered before the slab is cut while there are still options.
- They will also hand finish the edges and color match them to the top of the granite. If edges are not hand finished, you will be able to see small vertical lines along the edge of the countertop left by machinery.
- Layout- Before any cuts are made your base kitchen cabinets should be installed, leveled and a template should be made to fit your kitchen design precisely. Your designer or builder should identify the best place for necessary seams and help you identify which part of your slab you want to highlight and where you want to be placed.
- Support your supplier should also identify necessary support for overhangs at the time of template and notify your designer or builder if any additional support is needed.
- Finish the slab completely including overhangs this makes for a comfortable surface and a professional finished look.
Install
Ask your designer or builder to refer a good installer, some designers and builders provide their own contractors, and sometimes the supplier also performs the install. Make sure your installer follows these guidelines.
Another thing to consider is who is liable for any damage done to your granite if it becomes damaged during install. If you buy through a kitchen design or build company and have entered a contract the company would be liable. If you buy it independently you may or may not be covered, make sure you clarify this before moving forward with a granite purchase.
- Install steel rods around all cutouts. Steel Rods are installed on the underside of the granite it is a technique used to create a structurally sound opening in the stone for cooktops, sinks, etc. to prevent cracking.
- When installing an undermount sink the fabricator should use steel brackets or sink setters instead of relying on epoxy or silicone alone to hold the sink in place otherwise you run the risk of your sink falling off.
- Seams between stone pieces should be 1/8” with a tolerance of +/- a 1/16th of an inch, anything larger is distracting and anything thinner does not provide a strong enough bond between pieces.
- The top should fit tight to the wall and all adjoining permanent vertical surfaces any gap should not exceed 3/16th of an inch.
- Edges should be caulked to prevent moisture and food particles from collecting and to hold the stone in place.
- Granite should be completely dry before sealing and sealed with a minimum 15 year sealer.
A good installation team will also be courteous and keep your space clean, they should tape your drawer guides during the install to keep dust out, protect your cabinetry and clean up the jobsite after your countertop install is complete. A good countertop install can make or break a kitchen remodel, make sure you are putting your investment in the hands of kitchen remodeling experts.
