Five Questions You Must Ask Your Worktop Fitter Before Installation

The quality of your worktop installation matters as much as the quality of the stone itself. A beautiful slab fitted by an inexperienced team can result in uneven overhangs, visible joints, sink cutouts that do not align, and structural failure over time. Before you commit to any supplier, these are the questions that separate the professionals from the rest.

1. How Do You Conduct the Template?

There is only one acceptable answer: digital laser templating. Traditional wooden or paper templates are prone to human error that can result in gaps, misaligned cutouts, and a poor fit against walls that are naturally out of square. Any company still using manual templates is not operating to current professional standards.

2. How Will You Handle the Joints?

For larger kitchens, joins between worktop sections are unavoidable. Ask how the supplier plans the slab layout to minimise their number and placement. Professional fabricators use colour-matched epoxy adhesives applied with precision to render joints virtually invisible. Request to see examples of completed installations before committing.

3. What Exactly Is Included in the Price?

Some companies quote a low per-square-metre price and then add charges for templating, edge profiling, sink cutouts, delivery, and installation separately. Before you sign anything, get a fully itemised quote that explicitly confirms every element is included.

4. Can You Confirm the Brand and Origin of the Stone?

Unbranded, imported stone blanks frequently lack the quality control, colour consistency, and durability of certified manufacturers. Always confirm the specific brand and collection. Reputable manufacturers such as Silestone, Caesarstone, and Compac carry transparent quality standards and warranties that protect your investment.

5. What Guarantees Do You Provide?

You need two guarantees: the manufacturer warranty on the stone itself (typically 10 to 25 years) and the installer's workmanship guarantee. Ask for the workmanship guarantee in writing. A reputable company will provide at minimum five years on their workmanship; the best offer ten. At Stoneone, every installation carries a ten-year workmanship guarantee as standard.
