Best Practices for a Smooth Upgrade and Stunning Results

Upgrading from outdated Formica or older stone to new granite, quartz, or quartzite countertops can completely transform your kitchen or bathroom. But when your cabinets aren’t brand new, extra care is essential to make sure the installation looks beautiful and lasts for years.
Whether you’re working with older wood cabinets or pre-existing stone removal, the details matter. At Blue Ridge Granite, we’ve helped countless homeowners in Greenville, SC, achieve the kitchen countertops of their dreams—while ensuring the foundation is solid. Here’s what you should know before moving forward.
1. Checking Cabinet Strength and Stability
Stone countertops are heavy. Granite and quartz slabs often weigh between 18–25 pounds per square foot. Before installation, it’s important to confirm that your cabinets can safely support the added weight.
Inspect the structure. Look for signs of sagging, loose joints, or wood damage.
Check the level. Uneven cabinets can create gaps that make seams more visible or cause stress cracks in the stone.
Secure reinforcements. In many cases, adding extra support brackets or reinforcing the frame is a smart move.
2. Removing Old Countertops the Right Way
If you currently have Formica or another laminate, removal is usually straightforward. Older stone, however, can be trickier. Proper removal prevents cabinet damage and ensures a smooth surface for new installation.
Formica: Typically glued to plywood; removal involves prying carefully to preserve the cabinet structure.
Stone: Requires professional handling to avoid breakage that could damage the cabinets.
3. Preparing for the New Countertops
Preparation is everything. A well-prepared base guarantees a clean, polished final look.
Clear the workspace. Remove appliances, sinks, and plumbing connections before templating.
Plan for sink and faucet cutouts. Let your fabricator know your exact fixtures in advance.
Choose an edge profile that complements the cabinet style. This detail ties the look together.
4. Finishing Touches That Elevate the Look
Backsplash decisions: Decide whether to use matching stone or tile before installation day.
Overhangs and support: Larger overhangs may need corbels or brackets for safety and style.
Sealing and care: Ask about sealing schedules for natural stone to keep it looking new.
Final Thoughts
New stone countertops can completely redefine your kitchen or bathroom, even when working with older cabinets. With proper preparation, professional guidance, and attention to detail, you’ll enjoy a result that feels brand new and elevates your entire space.
