General Cleaning

The roof and side frames of your conservatory should be washed down every four months with a soap water solution to remove grime and atmospheric deposits.


Frames only - to remove any stubborn blemishes use a strong, nonabrasive, proprietary cleaner such as cream cleanser (eg CIF).

Please Note: Never use powerwashers


Your double glazed products are designed with an inbuilt drainage system, comprising slots within the thresholds that allow any water ingress to flow to the outside. To ensure an efficient system these slots must remain unblocked. Periodically remove dirt, clear drain holes and check drainage operation by flushing through with water.


Ensure that the weatherseals fitted to your doors and windows do not become dislodged during cleaning. If this does occur simply slide the seal back into place immediately to avoid damage when the product is closed. If the weatherseals are broken or damaged and draughts can be felt, contact your installer promptly to arrange for a replacement.

Gutters & Box Gutters

In a conservatory the guttering is always laid level in accordance with BS EN 12056 Parts 1,3 & 5 Code of Practice for Drainage of Roofs. Therefore you will notice standing water in your gutter system. It is important that you clean the gutters regularly – be sure to use crawl boards if accessing a conservatory roof.

To find a contractor to clean your conservatory (we would not recommend you clean it yourself), please look at the listings alongside. Please be aware we have not vetted these companies, so please satisfy yourself as to their probity before engaging them.

These companies can offer a 'deep' clean of your structure and glazing, they may even clean the gutters. Always make sure you agree with them what is/isn't covered before you engage them. Please see our generic guidelines here for cleaning and maintenance - use it as a checklist to make sure your cleaning company does the job right.

A grubby conservatory is never going to be pleasant to sit in, but when it comes to cleaning, things can be a little bit tricky. With a little time, a decent hoover and a feather duster, it's easy enough to keep the inside of your conservatory spic and span

Keeping Your Conservatory Clean: A Quick 5-Step Guide

1. Avoid the lure of the power washer

You may be tempted by their promises of blasting off the dirt in minutes, but using a power washer on your conservatory can be a costly mistake. Power washers are strong, and the force they use to clean could be too much for your new room, so it's best to steer clear.

If you do use a power washer, you could find that your conservatory’s panels get dislodged, and this can be pricey to fix. Instead, it's time to employ a bit of elbow grease. You'll need a telescopic window cleaner and uPVC/window solvent cleaner to help shift the dirt.

When washing the outside, make sure that you start from the top and work downwards - that way, the glass panels at the bottom will have had a good soaking before you tackle them, so they'll be much easier to clean.

2. Don't climb up on to your structure’s roof

Don’t put yourself at risk of injury by making shortcuts. Instead, use a ladder to climb up to roof level, use a brush to sweep away any dirt and then use your telescopic window cleaner to reach up to the roof and give it a good wash down.

3. Make sure that you maintain your roofline

Gutters can easily become cluttered with leaves and moss, so make sure you give these a good clean out - especially in autumn when the leaves are falling. Your conservatory will last longer and look more aesthetically pleasing this way.

4. Prevent the damaging build-up of moss

Treat your conservatory with a solution to remove any moss and mould that might have built up. This should be applied after you have swept and washed your structure, and it will hopefully help prevent any future build-up.

5. Look after the inside of your conservatory

Check the inside of your conservatory for moss or mould, too. If it is poorly ventilated, this could be a problem. You can use warm water with washing up liquid to clean the inside, which shouldn't damage your conservatory seals.

How Else Can You Protect Your Conservatory?

Maintaining your conservatory is vital if you want to prevent it from falling into disrepair and ensure it continues to add value. But if your structure is older, it may no longer be performing to the high standards needed to keep your home thermally efficient.

How can you prevent your conservatory from detracting from deteriorating? You don’t necessarily have to replace the entire structure and start again; a high-performing replacement roof would solve the issue and at a fraction of the cost.

Which Replacement Conservatory Roof is Best?

Ultraframe can offer its customers an eclectic range of replacement roofs, including:

Livinroof. This is a solid roof that features aluminium panels that can be replaced with glazing shaped to suit individual requirements. It locks in heat to keep a conservatory warm, but without forcing the homeowners to sacrifice on light.

Ultraroof. This high-performing product can accept the introduction of glazed panels or Velux windows, which means it can be customised to suit a homeowner’s design preferences and combines the benefits of glass and solid roofs.

Thermally Efficient Glass and Ventilation Will Protect Your Conservatory

Keeping your conservatory the perfect temperature all year round is important if you want to use it as an additional room and avoid the occurrence of issues that are expensive to fix.


Our roofs can be fitted with different types of ventilation and as follows:

  • Trickle ventilation. This is included as standard and allows a constant flow of air into the room, preventing condensation and stopping your room getting too warm.
  • Eavesflow ventilation. This type of ventilation encourages cross-flow ventilation and convection to ensure fresh air continues to circulate within your conservatory.
  • Roof Ventilation. These vents can be manually operated or work automatically. The latter is fitted with intelligent rain and thermostatic sensors that react to the environment.
  • Ceiling Fans. Add a touch of style to your room and keep cool air circulating with our manual or remote-controlled range of decorative ceiling fans.
