There comes a point with any carpet, usually around a spilled glass of red or a muddy dog, when a vacuum no longer cuts it. You can hire a machine and spend a damp afternoon on your knees, or call in a professional and have it done properly in an hour. Portsmouth has plenty of the latter, and the good ones are very good indeed.

To find them we read through hundreds of reviews and weighed each firm on the same measures. The cleaning results came first, then the range of work, from carpets to upholstery and stain restoration, how fair the prices are, and how reliable they are on the day. Results and value did most of the talking.
Reviews carried the most weight, because a deep clean either works or it does not, and customers say so plainly. We revisit the list as firms earn their name.
The five run from our top pick downwards, starting with the best.
1. Royal Cleaning and Restoration Portsmouth
Top of the list by a clear margin, Royal holds a perfect 5.0 from more than two hundred and forty reviews, a huge base for a cleaning firm. It covers carpets, upholstery and proper stain and flood restoration, and the reviews are full of before-and-after stories of carpets written off and then saved. This is the one to call when a clean needs to be a rescue.
“Got red wine out of a cream carpet I’d given up on,” reads one glowing review. A single room sits around £35 to £45 and a whole house from roughly £120, so the results come at a fair price.
What stands out
- A perfect 5.0 from 240-plus reviews, by far the biggest;
- Carpets, upholstery and flood restoration;
- A track record of saving written-off carpets;
- Fair prices for the results.
A couple of caveats
- Deservedly busy, so book ahead;
- Restoration jobs are quoted after a look.
The clear first call, from a routine clean to a full rescue.
2. The Carpet and Upholstery Cleaners
As the name says, this is the dedicated specialist, and a perfect 5.0 from more than fifty reviews shows it does the one thing properly. Carpets and upholstery are the whole business here, from sofas and dining chairs to stair runners, with the kit and the know-how to match. Reviewers single out careful work and sensible advice on what will and will not shift.
Prices are competitive, with a three-piece suite around £60 to £80. For upholstery in particular, a specialist who does nothing else is a reassuring choice.
Where it shines
- A dedicated carpet and upholstery specialist;
- A perfect 5.0 from 50-plus reviews;
- Honest advice on what will shift;
- Competitive, clear pricing.
Where it dips
- Less geared to flood or fire restoration;
- A smaller operation, so book ahead.
The specialist pick, especially for tired upholstery.
3. Prestige Cleaning Company
A 5.0 from more than thirty reviews makes Prestige a dependable all-rounder, handling carpets alongside domestic and end-of-tenancy cleaning. That breadth is handy when a carpet clean is part of a bigger job, such as moving out of a rented flat and needing the whole place to pass inspection.
Pricing is fair and quoted to the job, with carpet rooms in the usual £35 to £45 range. For a combined clean around a move, it saves booking two firms.
The strong points
- A 5.0 from 30-plus reviews;
- Carpets plus domestic and end-of-tenancy;
- Handy for a clean around a move;
- Fair, job-based pricing.
The weak points
- A generalist rather than a carpet specialist;
- A smaller review base than the leader.
The pick when a carpet clean is part of a bigger job.
4. ServiceMaster Clean Portsmouth
The national name on the list, ServiceMaster carries a 4.8 locally and the backing of an established franchise behind it. That means consistent methods, proper insurance and the reach to handle bigger commercial and restoration jobs as well as a front room. For landlords and offices in particular, the brand reassurance counts.
Prices sit a touch above the small independents, which is the trade-off for the scale and the paperwork. For a job that needs an audit trail, it is money well spent.
Reasons to go
- An established national franchise;
- Consistent methods and proper insurance;
- Handles commercial and restoration work;
- Reassuring for landlords and offices.
Reasons to pause
- Pricier than the small independents;
- A smaller local review base so far.
The pick for commercial jobs and landlord peace of mind.
5. The Kleen Machine
Rounding off the five, The Kleen Machine earns its 5.0 from a smaller set of reviews for straightforward, good-value carpet cleaning. It is the no-fuss local choice for a standard refresh, with customers praising a friendly, on-time service and a noticeable result for the money.
Pricing is keen, which makes it an easy call for a couple of rooms before guests arrive. The review count is modest, but the feedback is consistently warm.
Good to know
- A 5.0 from a smaller review base;
- Straightforward, good-value cleaning;
- Friendly and on time;
- Keen prices for a standard refresh.
Bear in mind
- Fewer reviews than the top names;
- Less suited to heavy restoration work.
The budget-friendly pick for a straightforward refresh.

What the ranking shows
The scores say the field is strong, with near-perfect ratings almost across the board. What sorts them is what they can handle when a clean turns into a rescue.
Royal pulls clear because flood and stain restoration, backed by a huge review base, is a different league from a routine refresh. Below that the choice is about fit, a dedicated specialist for upholstery, a generalist for a clean around a move, or a national name for a landlord’s paper trail. On price the field is close, so booking is often about who can come soonest.

How we scored
Each firm earned its mark on five counts. Reviews and reputation made up about 35 per cent, the cleaning results for 25 per cent, value and price for 15 per cent, the range of work handled another 15 per cent, and reliability and communication the final 10 per cent.
The ratings come from public Google reviews, read in late 2026. On price, a single room tends to run around £35 to £45, a three-piece suite £60 to £80, and a whole house from about £120, and we judged value against those bands. This is an editorial snapshot, not an official ranking, and the order moves as reviews build. Always confirm the price and what is included before booking.
