A plain-English breakdown of the most common quartz misconceptions we hear in our Pin Green showroom. The myths cost Stevenage homeowners money and bad worktop choices. Here is the honest version of the story.
4.8 from 515+ Google reviews · Stevenage & Cambridge showrooms
Walk into any quartz showroom in Hertfordshire and you will hear the same handful of myths repeated by customers who have done their research online. Some are harmless. Others lead Stevenage homeowners towards genuinely bad decisions like the wrong slab, the wrong installer or the wrong cleaning routine. Twenty years of fitting quartz tells us which myths matter and which can be safely ignored.
This page is the seven-myth list we run through with anyone who has been reading too many forum posts. Each one comes with the truth behind it, what the misconception costs in real terms and how to spot the same myth dressed up differently. Print it off if it helps. We would rather every homeowner walked into our showroom or any other supplier knowing the actual facts about the material.
The myths cost more money than the worktops do. Most expensive bad decisions in our showroom start with one.

How often we hear each myth
An informal tally from our showroom team across a year of customer conversations. The same misconceptions come up again and again.
Five misconceptions account for most of the confusion
The myth we hear most often is that quartz is heat-proof. Roughly four in ten Stevenage customers walk in believing they can put hot pans straight onto the slab. The next most common is that all quartz brands are essentially the same, which leads people straight to the cheapest quote without checking what they are actually buying.
After those, the picture is more mixed. Some people think quartz is a natural stone like granite. Others think it needs sealing every year like marble. The smaller myths add up too which is why a clear list is genuinely useful before you start visiting showrooms.
Engineered stone
Heat-resistant only
No sealing ever
Brands differ a lot
Which myths catch which Stevenage properties out
Different homes hear different versions of the same misconception. Here is the pattern we see across the local property mix.
New builds in Great Ashby
Often hear the heat-proof myth from the previous owner or the developer. The result is hot pan damage in the first six months. The myth costs more than a trivet would have done.
1930s semis near Old Town
Tend to hear the all-brands-are-the-same myth and end up with a budget Chinese slab that does not perform like the Belenco or Caesarstone they thought they were getting.
Family homes in Chells
Often catch the indestructible myth and treat the worktop accordingly. Cutting straight on the surface and slamming pans down accelerates wear on a slab that should have lasted twenty years.
Renovated council homes
Can hear the needs-sealing myth from a friendly neighbour with a granite worktop. Then waste money buying products quartz does not need and which actually damage the polish.
What homeowners get wrong about cost
Pricing carries its own set of myths. Here is what is actually true at each Stevenage band.
- Myth: cheap = lower quality stone
- Truth: lower brand, same Mohs 7
- Still 15-year lifespan if fitted right
- Right tier for first family kitchens
- Myth: pay extra for better stone
- Truth: pay for fabrication and fit
- The slab is similar to standard tier
- Best 20-year value bracket
- Myth: only for big budgets
- Truth: signature ranges plus warranties
- Bookmatched and waterfall edges
- Highest resale impact tier
Most homeowners assume premium tiers buy a stronger slab. The actual upgrade is fabrication, edge profiles, brand warranties and finishing detail.
Quartz is heat-resistant, not heat-proof. The single most expensive myth on this list. One scorched slab costs more to remedy than a lifetime of trivets.
See the truth in person, not in a forum
The fastest way to bust every myth on this page is to come into our Pin Green showroom. Press the slabs. Ask the awkward questions. Take samples home. Real evidence beats any internet thread.
Myth vs reality, side by side
A quick reference table for the most common claims about quartz versus what is genuinely true.
| Reality | The myth | The cost of believing it | |
|---|---|---|---|
| Heat tolerance | Resistant up to 150°C | Heat-proof | Scorched slab |
| Sealing | Never needed | Annual sealing | Wasted spend, dulled polish |
| Material type | Engineered stone | Natural quarried stone | Wrong expectations |
| Brand difference | Significant | All brands the same | Lower-grade slab |
| Damage resistance | Very high | Indestructible | Cracked corners |
| Fade resistance | High indoors | UV proof | Faded outdoor kitchen |
| Cleaning | Soapy water only | Bleach is fine | Damaged resin |
Seven quartz worktop myths debunked properly
The seven most common misconceptions we hear. Each one with the actual truth and what it means for your kitchen choices.
Myth: quartz worktops are completely heat-proof
The truth is that quartz handles moderate heat well but the resin component scorches under direct contact above roughly 150°C. Always use a trivet for very hot pans. This is the most expensive myth on the list.
Myth: all quartz brands are essentially the same
They are not. Premium brands like Belenco, Caesarstone and Silestone deliver longer warranties and more consistent slab quality than budget options. The slab itself rarely fails but the warranty cover differs significantly.
Myth: quartz is a natural stone like granite
Quartz is engineered. Roughly 93% ground natural quartz crystals bonded with about 7% resin and pigment. This is what gives it the non-porous performance granite cannot match without sealing.
Myth: quartz needs sealing every year
It does not. Quartz is non-porous which means there are no pores for a sealer to fill. Applying granite sealer to quartz wastes money and can dull the polished finish.
Myth: quartz is indestructible
It is genuinely durable. It is not invincible. Sharp impacts on edges and corners can chip the slab. Heavy items dropped from height can crack a thin section. Treat it with reasonable care and it will outlast the kitchen around it.
Myth: bleach is the best cleaner for quartz
Bleach and other strong alkaline or acidic cleaners break down the resin in quartz over time and dull the polish. Warm soapy water and a microfibre cloth is the only daily routine quartz actually needs.
Myth: quartz fades quickly in sunlight
Indoors it does not fade. The myth comes from people using quartz in unsuitable outdoor settings. For garden kitchens or sun-facing conservatories, granite or Dekton is the right call. Anywhere else, quartz holds its colour for decades.
How misconceptions spread through the buying journey
Each myth has a typical source. Knowing where it came from helps you spot it dressed up differently elsewhere.
Anecdotal claims
Hot pan stories, brand bashing, sealing advice from people with granite, all repeated as fact.
Cross-pollinated advice
Granite owner gives sealing advice. Marble owner gives stain advice. Neither applies to quartz.
Sales soundbites
Cheaper suppliers talk up “indestructible” and “heat-proof” to close the sale. Both go too far.
Care guide skipped
Without written aftercare, homeowners default to assumptions. That is when the bad habits start.
Damage shows up
Scorch marks, dulled polish or chipped edges appear. The myth becomes the cost of repair.
The three myths that cost homeowners the most
Of all the misconceptions on the list, these three are responsible for the lion’s share of the avoidable damage we are called in to repair.
Quartz is heat-proof
Hot pan damage is permanent. The resin scorches and discolours. There is no spot repair. The piece must be cut out and replaced. This single myth costs Stevenage homeowners hundreds of pounds in remedial work every year.
All brands are the same
Not true. Lower-grade unbranded slabs have higher resin content, less consistent colour and shorter warranties. The saving at quote stage gets eaten up over twenty years of inferior performance.
Bleach is the best cleaner
Bleach breaks down the resin layer slowly. Six months in, you start to see the polish dulling. Once it has happened, it cannot be polished back without professional refinishing. Stick to soapy water.

Quick answers
Can I really not put hot pans on quartz?
You can put a warm pan on quartz without issue. What you cannot do is take a cast iron pan straight from the hob and rest it directly on the slab. The temperature differential causes the resin component to scorch and discolour. Always use a trivet for cookware that has been on the heat.
Does quartz really not need sealing?
Correct. Quartz is non-porous which means there is nothing for a sealer to fill. Applying granite sealer to a quartz worktop wastes money and can leave a tacky residue that dulls the polished finish. Save your money and your worktop.
Are cheap quartz brands genuinely worse?
The slab itself is similar across most brands at the structural level. The differences are in the consistency of pattern, the resin content, the brand warranty and the long-term colour stability. Premium brands deliver more reliably across all four.
Can I cut directly on a quartz worktop?
Quartz is harder than most kitchen knives, so it will not scratch easily. However, the impact and friction will damage your knives faster and may leave subtle marks on the polish over time. Always use a chopping board.
Does quartz really stain from things like turmeric or red wine?
It can stain mildly if a strongly pigmented spill is left on the surface for many hours. Wiped within an hour, it leaves no mark. Soft cleaners like Bar Keepers Friend or Cif will remove most residual marks if a stain does sit too long.
