Frequently Asked Questions
Kitchen Worktop FAQs | Quartz, Granite & Porcelain Worktops in Buxton
Got questions about quartz, granite or porcelain worktops? We’ve answered the most common questions below, from choosing the right material to templating, installation, cleaning, aftercare and areas we cover.
Choosing Your Worktop
The best kitchen worktop material depends on how you use your kitchen, the style you want and how much maintenance you are happy with.
Quartz is a popular choice because it is low-maintenance, consistent and available in a wide range of colours. Granite is natural, strong and unique, with every slab having its own pattern. Porcelain is extremely durable and works well for modern kitchens, dramatic splashbacks and marble-effect designs.
During your design consultation, we help you choose the right surface for your kitchen rather than simply pricing the cheapest option.
Is quartz better than granite?
Quartz is usually better if you want a consistent finish and low maintenance. Granite is better if you want a natural stone with unique patterning and character.
Quartz does not normally need sealing, whereas some granite surfaces may need sealing over time. Granite is very strong and heat-resistant, but quartz is often easier for everyday family use.
Is porcelain good for kitchen worktops?
Yes. Porcelain is a premium worktop material that is very hard-wearing, resistant to heat, and ideal for modern kitchens. It is especially popular for large islands, sleek worktops, full-height splashbacks and dramatic marble-effect designs.
Porcelain is extremely durable, but like most hard surfaces, it can chip if struck with force on an edge or corner.
Should I choose 20mm or 30mm worktops?
20mm worktops create a sleek, modern look and are often used in contemporary kitchens. 30mm worktops give a thicker, more traditional appearance.
Both can work well. The right choice depends on your kitchen style, cabinet design, material choice and budget.
Can I see samples before choosing?
Yes. Samples are important because worktop colours can look different depending on your lighting, cabinets, flooring and wall colours. We recommend viewing samples in your own home where possible.
Pricing & Quotes
How much do quartz worktops cost?
Quartz worktop prices depend on the material, kitchen size, number of slabs, cut-outs, sink type, hob type, upstands, splashbacks, drainer grooves, edge details and installation requirements.
A simple straight run will usually cost less than a kitchen with an island, undermount sink, drainer grooves, waterfall panels or full-height splashbacks.
Why do worktop quotes vary so much?
Worktop quotes vary because not every quote includes the same level of service or detail. Some may include templating, fabrication, fitting and VAT. Others may add certain items later.
At Keystone Worktops, we aim to make the quote clear so you know what is included before moving forward.
What do you need to quote my worktops?
To provide a quote, we usually need your kitchen plan, rough measurements or photos, your postcode, the material or colour you like, and details such as sink type, hob type, upstands, splashbacks, drainer grooves, radiuses, overhangs and any island or seating areas.
This is also where we can spot design details that may affect the price or final finish.
Do you offer a free design consultation?
Yes. Keystone Worktops offers a free design consultation to help you choose the right material, colour, layout and finish.
We can talk through practical details such as sink position, tap holes, hob cut-outs, upstands, splashbacks, overhangs, joints, edge profiles and care.
Our Process
What is the Keystone Worktops process?
Our process is designed to make choosing and installing your worktops as simple as possible.
First, we start with a free design consultation to understand your kitchen, style, budget and layout. We then help you choose the right material, colour, thickness, edge details and finishing options. Once you are ready to move forward, we arrange templating, fabrication and installation.
The usual process is:
Design consultation → Quote → Material choice → Templating → Fabrication → Installation → Aftercare
Our goal is to guide you through the full journey, not just sell you a slab of stone.
Can you help if I do not know what worktop I want?
Yes. Many customers come to us knowing they want “stone worktops” but are unsure whether quartz, granite or porcelain is right for them.
We help you compare the materials, colours, finishes and practical details so you can make a confident decision. We can also advise on upstands, splashbacks, edge profiles, sinks, drainer grooves, overhangs and seating areas.
Can you quote from photos?
Yes. In many cases, we can provide an estimate from photos, rough measurements or a kitchen plan.
The final price may need to be confirmed after templating, especially if there are complex details such as islands, full-height splashbacks, undermount sinks, waterfall panels, large overhangs or unusual wall shapes.
Do you offer virtual appointments?
Yes. We can discuss your project by phone, message, video call or in person depending on what suits you best.
This is useful if you are still at the planning stage or want early advice before committing to a worktop choice.
Templating & Installation
What is worktop templating?
Templating is the process of taking accurate measurements before your worktops are made. It confirms the size, shape, wall lines, sink cut-outs, hob cut-outs, tap holes, joints, overhangs, upstands and splashbacks.
Good templating is one of the most important parts of getting a high-quality finish.
What needs to be ready before templating?
Before templating, your base units should be fixed, level and in their final position. Sinks, taps, hobs and appliances should either be fitted or available on site so their positions can be confirmed.
Old worktops, temporary worktops, tiles or splashbacks may need to be removed depending on the project. Pre-template checklists from other worktop suppliers also commonly highlight that surfaces should be clear, sinks and hobs should be positioned, and old tiles or splashbacks should be removed before templating.
Do I need to be there for templating?
Ideally, yes. It helps if you or someone who understands the kitchen design is there to confirm important details such as sink position, hob position, tap holes, drainer grooves, overhangs, radiuses, joints and splashbacks.
How long does installation take?
Most standard kitchen worktop installations are completed in one day. Larger or more complex kitchens may take longer, especially if there are full-height splashbacks, large islands, heavy stone, awkward access or multiple rooms.
What happens after templating?
After templating, the measurements are sent for fabrication. Your worktops are then cut, polished and prepared before installation. Once ready, the fitting team returns to install the worktops, check the finish and complete the final details.
Practical Site Questions
Do I need a plumber before worktop installation?
If you are having a sink, tap or boiling water tap fitted, a plumber may be needed to disconnect and reconnect the plumbing.
Stone fitters usually install the worktops and sink cut-outs, but plumbing connections are normally handled separately by a qualified plumber.
Do I need an electrician before worktop installation?
If you are having pop-up sockets, hob wiring, under-cabinet lighting or socket cut-outs in a splashback, an electrician may be needed.
We can help plan the stone cut-outs, but electrical work should be completed by a qualified electrician.
Can you cut around pillars, alcoves or uneven walls?
Yes. This is one of the reasons templating is so important. Walls are not always perfectly straight, especially in older properties.
Templating allows the worktops to be measured properly around walls, pillars, alcoves, units and other details.
What access do you need for installation?
Stone worktops are heavy, so safe access is important. We need to consider parking, doorways, steps, tight corners, stairs, islands, large slabs and the number of people required to lift safely.
If access is difficult, we will discuss this before fitting.
Design Details
What are upstands?
Upstands are low stone pieces that run along the back of your worktops where they meet the wall. They help protect the wall from splashes and give the kitchen a neat, finished look.
What is the difference between an upstand and a splashback?
An upstand is usually a shorter strip of stone along the wall. A splashback is usually taller and is often fitted behind a hob or sink.
A full-height splashback can create a premium look because the stone continues from the worktop up the wall.
What are drainer grooves?
Drainer grooves are shallow grooves cut into the stone beside an undermount sink. They allow water to drain back towards the sink and create a clean, built-in look.
Before templating, we confirm which side the grooves should go on and where they should sit.
Can I have an undermount sink?
Yes. Undermount sinks work well with quartz, granite and porcelain worktops. They create a clean finish because the sink sits below the stone rather than on top of it.
The sink needs to be available for templating so the cut-out can be measured accurately.
What are hob cut-outs?
Hob cut-outs are the openings made in the stone for your hob. These need to be measured carefully so the hob fits correctly and safely.
If you have a range cooker, we also need to allow the correct tolerance and ventilation gaps.
Can I have pop-up sockets in my worktops?
Yes. Pop-up sockets can be added to islands and worktop areas where you want power for appliances, charging docks or general kitchen use.
Socket positions should be decided before templating so the cut-outs can be planned accurately.
What are edge profiles?
An edge profile is the shape of the front edge of your worktop. Simple modern kitchens often use clean pencil or chamfered edges. More traditional kitchens may suit softer or more decorative profiles.
The edge detail can change the feel of the whole kitchen.
What is a waterfall edge?
A waterfall edge is where the stone continues down the side of an island or cabinet to the floor. It creates a premium, seamless look and works especially well on kitchen islands.
How much overhang should I have?
A standard worktop overhang is often around 20mm, but this depends on the kitchen design. Handleless kitchens may need a smaller overhang so drawers and doors still work properly.
Seating areas and breakfast bars need more thought because larger overhangs may require additional support.
Can I have a breakfast bar or seating area?
Yes. Breakfast bars and island seating areas are popular, but the overhang needs to be planned properly.
A seating overhang is often larger than a standard overhang, so we need to consider legroom, stool position, stone strength and whether support brackets or legs are required.
What are radiused corners?
Radiused corners are rounded corners added to worktops, islands or seating areas. They can soften the look of the kitchen, make corners safer in walkways and help prevent sharp edges from being damaged.
What is a waterfall edge?
A waterfall edge is where the worktop continues down the side of an island or cabinet to the floor. It creates a seamless, premium look and is often used on kitchen islands or feature ends.
It works especially well with marble-effect quartz or porcelain because the pattern can create a strong design statement.
What is a breakfront?
A breakfront is where the worktop projects forward from the main run of cabinets, often around a sink, range cooker or feature area.
It can add character and detail, especially in more traditional or shaker-style kitchens.
Can I have LED lighting with stone worktops?
Yes. LED lighting can work well with stone worktops, especially under cabinets, along splashbacks or around feature areas.
Lighting can change how your worktop looks, so it is worth thinking about early in the design stage.
What are socket cut-outs?
Socket cut-outs are openings made in the stone for pop-up sockets, wireless charging units or sockets in splashbacks.
These need to be planned before templating so the positions can be measured accurately.
Replacing Existing Worktops
Can I replace my worktops without replacing my kitchen?
Yes. Replacing your worktops can completely change the look of your kitchen without needing a full renovation.
Quartz, granite or porcelain worktops can make an existing kitchen feel more premium, especially when paired with a new sink, tap, upstands or splashback.
Before quoting, we would need to check the condition of your existing cabinets, layout, sink, hob and access.
Can you fit stone worktops onto existing cabinets?
Usually, yes, as long as the cabinets are strong, level and properly fixed.
Stone worktops are heavy, so the base units need to be suitable. If anything needs adjusting before templating, we will let you know.
Do old worktops need to be removed before templating?
It depends on the project. Sometimes old worktops can stay in place for an initial survey, but they may need to be removed before final templating or installation.
We will advise you before the template visit so everything is ready.
Cleaning & Aftercare
How do I clean quartz worktops daily?
Use a soft cloth or sponge with warm water and mild dish soap. Wipe spills quickly, especially acidic liquids such as lemon juice, vinegar, wine and coffee.
For a deeper clean, use a pH-neutral stone-safe cleaner. Avoid abrasive pads or harsh cleaning products.
What should I avoid using on stone worktops?
Avoid bleach, ammonia, vinegar, oven cleaner, acidic sprays, abrasive pads, wire wool, harsh alkaline cleaners and scouring powders.
You should also avoid standing or sitting on the worktop, dragging rough items across the surface, cutting directly on the stone, or placing hot pans directly on the surface.
Can I put hot pans directly on quartz?
It is best to use trivets or heat pads. Sudden temperature changes can cause cracks, marks or discolouration, especially with quartz or porcelain.
Even if a material is heat-resistant, using protection helps keep the surface looking its best for longer.
Can I cut directly on quartz, granite or porcelain?
No. You should use a chopping board. Cutting directly on the surface can damage knives and may mark or scratch the surface over time.
How do I prevent staining around the sink?
Wipe water away from sink areas regularly to help prevent mineral build-up and water marks. This is especially important in hard water areas.
Do granite worktops need resealing?
Some granite worktops may need resealing every 12 to 18 months depending on the stone and how heavily the kitchen is used. Marble may also need resealing if applicable.
How do I remove tough stains?
For oil or grease, use a stone-safe degreasing cleaner. For limescale, use a stone-safe limescale remover. For ink or dye, spot test with isopropyl alcohol first. For dried food, soften it with warm water and use a plastic scraper rather than a metal blade.

Keystone Care Plan
Do you offer worktop aftercare?
Yes. The Keystone Care Plan is designed to protect your stone worktops through professional maintenance and preventative care.
It can include professional deep cleaning, joint inspection and refresh, silicone inspection around sinks and upstands, minor chip inspection and touch-ups, stone resealing where required, and priority booking.
What is included in the Essential Care Plan?
The Essential Care Plan is £199 per year and includes a professional deep clean, joint inspection and refresh, silicone inspection, minor chip inspection and touch-ups, stone resealing where required, and priority booking for maintenance visits.
What is included in the Premium Care Plan?
The Premium Care Plan is £299 per year and includes everything in the Essential Plan, plus two professional maintenance visits per year, more frequent preventative care and priority scheduling.
How does the Keystone Care Plan work?
After installation, you can join the Keystone Care Plan. We then schedule your maintenance visit within the year. Your worktops are professionally cleaned, inspected, refreshed and resealed where required.
Why is aftercare important?
Stone worktops are designed to last for many years, but everyday use can slowly affect their appearance. Joints can dry out or discolour, silicone can break down around sinks and upstands, staining can build up, and small chips can go unnoticed.
Regular maintenance helps catch these issues early before they become bigger problems.
Safety & Quality
Are quartz worktops safe?
Quartz worktops are safe once installed and used normally in your home. The health risk is linked to silica dust created when engineered stone is cut, ground or polished during fabrication.
The HSE announced in May 2026 that dry cutting of engineered stone is unacceptable, water suppression is a legal requirement, and more than 1,000 inspections were being carried out across Great Britain.
Should I ask how my worktops are fabricated?
Yes. It is sensible to ask whether the stone is fabricated safely using proper dust control, water suppression and professional workshop processes.
A cheap quote is not always the best quote if corners are being cut behind the scenes.
Why does professional fitting matter?
Stone worktops are heavy, precise and difficult to adjust once cut. Professional fitting affects the final look, joint quality, sink position, hob position, overhangs, wall lines and long-term performance.
A well-fitted worktop should look like it belongs in the kitchen, not like it has simply been placed on top.

At Keystone, we help you think through the details before the stone is cut.
Is the cheapest worktop quote always the best option?
Not always. A cheaper quote may not include the same level of service, material quality, templating, fitting, aftercare or detail.
When comparing quotes, check what is included: templating, fabrication, fitting, VAT, sink cut-outs, hob cut-outs, drainer grooves, upstands, splashbacks, edge details and any extras.
A clear quote is usually better than a cheap quote with hidden extras.
What makes Keystone Worktops different?
Keystone Worktops is design-led. That means we do not just ask what colour you want and send a price.
We help you think about how the kitchen will actually work: how the sink sits, where the tap goes, how much overhang you need, whether the upstands suit the space, where the joints should go, how the stone works with your cabinets, and how to care for it after installation.
