Roof cleaning clears the debris and dirt that build up over winter, and it's a handy way to keep your conservatory looking neat between more thorough annual cleans.

How much does it cost to clean inside a conservatory?
Cleaning both the inside and outside of your conservatory costs around £475, depending on how thorough the job is.
Interior cleaning takes longer than cleaning just the outside, since it covers the floor, sills and interior frames as well as the glass. Some companies offer this alongside exterior cleaning; others only clean the outside.
You can even get what is known as a full valet service. This covers every nook and cranny of the exterior and interior of your conservatory, including:
Getting uPVC 'back to white' with specialist stain removal products
Applying water-repellent solution to glass panels
Cleaning and lubricating locks, hinges and door handles
It's always best to check with your conservatory cleaning company exactly what's included in their services.
How to clean a conservatory roof yourself
You can clean a conservatory roof yourself with warm water, a mild detergent and a soft-bristle brush or telescopic cleaning pole. An extendable tool means you don't need to climb a ladder.
Rinse thoroughly afterwards so no soap residue is left behind to attract more dirt. Avoid pressure washers: the force of the water can damage seals and coatings.

Factors affecting the cost of conservatory cleaning inside and out
Several factors affect what you'll pay for conservatory cleaning, from the size of the job to how thorough it is. Here are the main ones.
The size of your conservatory
As you might expect, the bigger your conservatory, the more you'll generally pay to have it cleaned.
Which parts you want cleaned
Interior cleaning costs more than exterior-only cleaning, since it takes longer. Not every company offers it: some only clean the outside, so check before you book.
How thorough the cleaning is
The more thorough your cleaning is, the more it will typically cost. A full valet service will generally cost the most. But make sure to check exactly what's included as this can vary from company to company.
Your location
As with any home improvement project, costs will vary across the country. In particular, costs tend to be higher in the South than in the North, and conservatory cleaning in London will typically cost the most.

Conservatory cleaning cost FAQs
If you're prepared to apply some elbow grease, you can clean your conservatory yourself, though it's tiring work and you'll need to be careful working at height on the roof.
Hiring is often a safer option: they'll complete the job quickly, with the right equipment and specialist products to get stained or faded conservatories back to white.
A thorough inside-and-out clean takes around four to five hours. Cleaning just the roof or just the exterior is quicker.
Aim for one deep clean a year, with a lighter clean in between. You don't need a weekly or monthly schedule unless your conservatory gets particularly dirty.
No, pressure washing your conservatory roof isn't recommended. The high pressure of water can damage seals and coatings. That said, specially designed low-pressure washers exist for this job.
The safest DIY option is warm soapy water with a soft brush or a telescopic pole, which cleans thoroughly without risking damage to panels or seals.
The best way to clean a conservatory is by hand with warm soapy water. Spirit-based cleaners and other harsh cleaning products can damage your conservatory, particularly any plastic sections.
If you need extra cleaning power, hiring conservatory cleaners near you is a good option, as they'll know which products suit your conservatory type and how to get good results without causing damage.
To keep your conservatory mould-free, control the condensation that leads to mould and mildew build-up. Ways to do this include:
Heating your conservatory
Installing conservatory roof blinds
Installing a dehumidifier
Increasing ventilation
Window cleaning prices in the UK start from around £35 for a semi-detached house.
Costs can vary depending on the size of your home, number of windows, accessibility and whether you're after additional services like cleaning windowsills and frames. A window cleaner near you will be able to give you an accurate quote.
In the UK, the average weekly cleaner cost (for 3 hours a week) is £25 per hour.
Costs depend on several factors, including whether you hire an agency or an independent cleaner, the type of cleaning you need, and whether you want regular or one-off services.
There are many different ways to make an old conservatory look good, some are big refurbishment projects and others are small hacks. A few ideas to consider include:
Installing new doors
Buying new furniture
Replacing your conservatory floor
Upgrading your conservatory lighting
Adding indoor plants
Painting your conservatory
Replacing your conservatory blinds

To get rid of green algae on a conservatory roof, use a soft brush with warm water and mild detergent for light algae, or a specialist conservatory roof cleaner or a diluted white vinegar solution for a stubborn build-up.
Avoid wire brushes or pressure washers, as both can scratch or damage the panels.
