Behind the Seams: Why Do Stone Countertops Have Seams?
Seams are a normal part of many stone countertop installations-and sometimes, they’re necessary.
Granite, quartz, and quartzite slabs only come in certain sizes, so larger countertops, long runs, L-shaped layouts, islands, or spaces with tricky access may require more than one piece.
Seams can also help:
- Make heavy stone safer to transport and install
- Work around corners, walls, appliances, and cabinets
- Reduce the risk of cracking during installation
- Make the best use of the slab and your layout
A professionally installed seam should be tight and secure, but it won’t be completely invisible. Every countertop project is a little different, and seam placement is part of the planning that goes into creating a beautiful, durable finished product.
