The Service
Conservatories go dull from the top down
Nobody looks at their conservatory roof. That's the problem. The roof is the surface that collects everything: tree sap, bird mess, leaf debris, algae, moss washed off the house roof and the black weathering film that settles on any horizontal surface; and it's the surface doing all the work of letting light in. A conservatory can lose a remarkable amount of daylight to a roof nobody has cleaned in five years.
Polycarbonate roofs are the worst affected. The corrugations and the box channels collect grime, and green algae grows inside the flutes where you can see it but can't reach it. Glass roofs stay clearer for longer but still film over, particularly if there are trees nearby.
The frames matter too. UPVC gets a grey-green build-up in the recesses and along the gaskets, and the trims and finials collect the same. Cleaned properly, the room brightens dramatically, which is usually the point at which people start using it again.
Who it's for
- Anyone whose conservatory feels dark, dingy and unused
- Households with trees nearby dropping sap, leaves and bird mess
- Owners of polycarbonate roofs with green growth in the flutes
- Landlords and agents presenting a property for let or sale
- Anyone wanting the room usable again before summer or Christmas
When it's needed
- Noticeably less light coming through the roof
- Green algae visible in the roof panels or along the frames
- Streaked, filmed glass that never looks clean
- Grubby UPVC frames with grey build-up in the recesses
- Conservatory gutters overflowing or full of debris
Why professional help matters
The obvious reason is access. A conservatory roof cannot be walked on, and reaching the middle of it safely requires the right equipment and technique; this is one of the more common DIY ladder-accident jobs.
The less obvious reason is method. High pressure aimed at a conservatory roof drives water past seals and gaskets and can damage panels and sealed units. Conservatories need controlled, appropriate cleaning, not force.
What Happens If You Leave It
A dirty conservatory quietly stops being a room
It happens gradually: the room gets dimmer, feels grubby, gets used less, becomes a place for storage, and then it's written off as 'wasted space', when all that was actually needed was a proper clean of the roof and frames.
You lose the light you paid for
The whole reason for a conservatory is daylight. A filmed, algae-covered roof takes a serious amount of that away, and because it happens slowly nobody notices until it's cleaned.
Algae takes hold in the panel flutes
On polycarbonate, growth inside the channels is visible, spreading and impossible to reach from inside, and the longer it's left, the more established it becomes.
Debris blocks conservatory gutters
Conservatory guttering is small and blocks fast. When it does, water backs up along the roof edge and runs down the frames and the house wall instead of away.
Seals and gaskets deteriorate
Trapped organic debris and constant damp sitting against seals shortens their life, and a failed seal on a roof panel is a leak into the room.
Sap and bird mess etch the surface
Both are acidic. Left through hot spells they bake on, become far harder to remove and can mark the panel surface permanently.
The room stops being used
A dim, grubby conservatory becomes a junk room. That's a whole room of your house effectively out of service.
The mistakes that cost people the most
- Climbing onto or leaning ladders against a conservatory roof: it isn't built to take weight.
- Blasting the roof with a domestic pressure washer and forcing water past the seals.
- Using abrasive pads or scourers on polycarbonate and scratching the panels permanently.
- Cleaning the glass but ignoring the frames, gaskets and gutters.
- Leaving bird mess and sap through a hot summer until they bake on.
- Ignoring the conservatory gutter entirely because it's small.
Our Process
The step-by-step system we use on every job
Assessment and quote
We look at the roof type (glass or polycarbonate), the frames, the gutters, access and condition, then agree the scope and a clear price before starting.
Safe access set-up
Access is planned so the roof is never loaded or walked on, with surrounding surfaces, planting and adjoining areas protected.
Roof panel cleaning
Panels are cleaned with appropriate methods and controlled water, never high pressure driven at seals, to lift algae, sap, bird mess and the weathering film.
Frames, trims and gaskets
UPVC frames, glazing bars, trims, finials and gasket lines are cleaned by hand where needed, since that's where the grey-green build-up hides.
Gutters and downpipes
Conservatory guttering is cleared and the outlets checked, because a clean roof draining into a blocked gutter causes exactly the problem you wanted solved.
Final rinse, check and guarantee
Everything is rinsed down, glass finished properly, the area left tidy, and the work backed by our service guarantee.
What You Get
Specific results, not vague promises
Dramatically more light
Clearing the roof is the single biggest change: most customers are surprised how much brighter the room becomes.
A room you use again
Clean, bright and pleasant means the conservatory goes back to being living space rather than storage.
No damage to panels or seals
Controlled methods rather than brute pressure protect gaskets, sealed units and the panel surfaces.
Gutters working properly
Clearing the conservatory guttering stops overflow running down frames and the house wall.
Longer life from the structure
Getting organic growth and standing debris off seals and frames slows the deterioration that leads to leaks.
Insured, guaranteed, safe
£5m public liability cover, a service guarantee, and no need for you to go anywhere near a ladder.
In Detail
Roof types, elements and situations we handle
Conservatories differ mainly by roof material and access, and both change how the job is done.
Roof types
- Polycarbonate: the most common and the most affected, with algae growing inside the flutes and channels.
- Glass and self-cleaning glass: stays clearer longer but still films over, especially near trees.
- Lean-to, Victorian, Edwardian and P-shaped structures with varying access challenges.
- Orangery-style roofs with larger frame areas and more trim to clean.
- Conservatory roofs adjoining a main roof, where moss washes straight down onto the panels.
What we clean
- Roof panels, ridge and glazing bars
- External glass and, where accessible and requested, internal glass
- UPVC frames, sills, trims and finials
- Gasket lines and recesses where build-up collects
- Conservatory guttering, outlets and downpipes
- Adjacent paving or decking, if you'd like it done at the same time
Situations we're called out for
- Conservatories that have never been cleaned since installation
- Heavy tree sap, bird mess and leaf staining
- Green growth visible inside polycarbonate flutes
- Overflowing conservatory gutters running down the wall
- Pre-sale and pre-let presentation
- Getting the room ready for summer or for Christmas
Domestic vs commercial
In homes, this is usually about reclaiming a room: light, cleanliness and comfort so the space is actually used again.
For businesses with glazed extensions, atria, canopies or garden rooms, it's about presentation and building maintenance, and often works best on a scheduled basis around opening hours.
Timing and keeping it clear
Spring is the most popular time, clearing off the winter's growth before the room comes back into daily use. Autumn, after leaf fall, is the other sensible point, especially where trees overhang.
In between, keeping overhanging branches trimmed back and making sure the main house gutters aren't discharging onto the conservatory roof makes a real difference to how fast it dirties again.

Questions People Ask
Conservatory Cleaning: your questions answered
How much does conservatory cleaning cost?
It depends on the size and style of the conservatory, the roof type, access and how heavy the build-up is. Quotes are free: send a photo and your postcode and we'll give you a clear price before booking.
How long does it take?
Most conservatories are completed in a single visit. We'll confirm the expected time when we quote so you can plan around it.
Can you clean a polycarbonate roof without scratching it?
Yes, polycarbonate scratches easily, so it's cleaned with appropriate methods and never with abrasive pads or aggressive scrubbing.
Do you clean the inside of the glass too?
We can clean internal glass where it's safely accessible, just mention it when you get your quote so it's included in the price.
Will you damage the seals or cause a leak?
We don't use high pressure aimed at seals and gaskets, which is what causes leaks after DIY cleaning. If we spot a seal already failing, we'll tell you rather than leave you to find out in the next downpour.
Do you clear the conservatory gutters?
Yes, and we recommend it: conservatory gutters are small and block quickly, and a clean roof draining into a blocked gutter still sends water down your frames and wall.
Can you remove the green algae inside the polycarbonate flutes?
We remove what's reachable and improve the appearance significantly. Growth that has established deep inside sealed channels may not come out completely, and we'll tell you honestly what to expect at assessment.
How often should a conservatory be cleaned?
Once a year suits most, usually in spring. Conservatories under trees or beneath a mossy main roof benefit from more frequent attention.
Are you insured, and is the work guaranteed?
Yes: £5 million public liability insurance and a service guarantee on every job, backed by 15+ years' experience and a 5.0 rating from 332 TrustATrader reviews.
Which areas do you cover?
