Carpet Cleaning vs Replacing — When Each Actually Makes Sense

Every week we get a phone call that starts: "I think we just need to bite the bullet and rip up the carpets — they're a state." Some of those carpets we save in a single afternoon. Some, honestly, we tell the customer to go ahead and replace.

Here's how to know which side you're on, with rough numbers so you can do the maths yourself before committing either way.

The honest cost comparison

For a typical 3-bed house in East Devon (lounge, dining, stairs, three bedrooms, landing — say 80m² of carpet), here's what you're realistically looking at in 2026:

• Professional clean of all that carpet: £130–180 in a single visit.
• Mid-range replacement carpet (~£18/m² supplied) + underlay + fitting: £2,100–2,800.
• Upper-mid carpet (~£28/m²): £3,300–4,000.
• Disposal of old carpet — most fitters charge ~£100–200.

So cleaning is roughly 5% the cost of replacing. That ratio is why most of the time cleaning is the right answer — but not always.

When cleaning will save your carpet

Cleaning is the right call if the carpet:

• Looks bad but is structurally sound — pile still upright, no bald patches, backing not crumbling, no major rips
• Is under 10 years old for synthetic, under 20 years for wool
• Has surface-level problems — traffic-lane wear, food spills, pet hair embedded in the pile, smell
• Has a stain or two that DIY hasn't shifted — most "permanent" stains aren't, with the right kit
• Smells musty / pet-y / smoky — almost always cleanable, even old smells

When replacing is genuinely the right call

Cleaning won't help you if the carpet has:

• Backing breakdown — you can see grey/black coming up through the pile, or the carpet ripples when you walk on it. The latex backing has failed; no clean fixes that.
• Bald patches or moth damage — wool carpets are vulnerable; once moths have been at it, you've got holes
• Burn marks — small ones we can sometimes patch from a hidden offcut, large ones means replacement
• Water damage — if a washing machine flooded it three weeks ago, the underlay is rotting underneath even if the carpet looks OK. The smell will come back forever.
• Asthma or allergy issues — older carpets accumulate dust mites, pet dander and pollen that no clean removes 100%. Sometimes a fresh start is genuinely the healthier option.
• Sun-bleach in patches — UV-faded carpets can't be re-dyed. Cleaning won't bring colour back.

The grey zone — try cleaning first

If you're 50/50, clean first. £150 to find out whether your carpet has a few more years in it is almost always worth it. We see this all the time:

• Customer convinced their carpet needs replacing. We clean it. They love it and keep it for another 4 years.
• Customer convinced their carpet needs replacing. We clean it. It's better but the wear shows. They use the year of grace to budget for the new carpet properly instead of panic-buying.

Either way you've spent 5% of replacement cost to know for certain.

How long should a carpet last anyway?

UK industry norm:

• Bedrooms: 10-12 years (low traffic)
• Lounge / dining: 8-10 years
• Stairs / hallway: 5-7 years (highest wear in any house)
• Holiday lets: knock 30-50% off the above — guest traffic is brutal

Professional cleaning every 12-18 months can extend each of these by 2-4 years easily. We've cleaned 22-year-old wool carpets that are still going strong.

The replacement gotchas no one tells you

If you do decide to replace:

1. Get three quotes. Carpet pricing varies wildly. The same roll can be £19/m² at one shop and £28/m² at another in the same town.
2. Check the carpet's "wear rating" — for stairs you want "extra-heavy domestic" minimum. Cheap carpets show traffic lanes in 2 years.
3. Underlay matters more than people think. A £15/m² carpet on premium underlay outlasts a £30/m² carpet on cheap underlay. Spend on underlay.
4. Don't forget gripper rods, scotia, doorbars. Quotes that look £200 cheaper often skip these and bill them later.
5. Plan two weeks notice — most fitters in East Devon are booked at least that far out.

One last thing about smell

If the main reason you want to replace is smell — pet, smoke, damp, mystery — bring us in first. Smells live in the carpet underlay and floorboards beneath, not just the carpet itself, so even a brand-new carpet can sometimes pick up a faint version of the old smell within months if you don't deal with the source. Professional carpet cleaning with enzyme treatments often resolves it. If it doesn't, you may need to lift the affected area and treat the subfloor — still cheaper than re-carpeting.
