Frequently asked questions
How should I choose a countertop installer?
Look for installers who work with the material you want, can show a portfolio of recent projects, and have consistent online reviews. Ask for written estimates, turnaround times, and details on who handles templating and installation so you can compare scope and reliability.
What influences the cost of a countertop installation?
Cost depends on material type, slab or product price, the size and layout of your countertop, edge profiles, sink and cooktop cutouts, and any required demolition or subcounter work. Get multiple written quotes and make sure each covers the same materials and scope to compare accurately.
What should I check before hiring a countertop shop?
Verify that the company has liability insurance and can provide references or photos of recent installs. Confirm who will handle templates, whether the installer provides seams, warranties, and the expected schedule to avoid surprises on install day.
