Can You Spray Paint a uPVC Conservatory? Costs, Process and Colours

Yes, a uPVC conservatory can be professionally spray painted. The frames, door, eaves beam, fascias and ridge capping are the same uPVC as your windows and take the same coating system. The glass and polycarbonate roof panels cannot be sprayed. Expect £400 to £800 for a lean-to and £700 to £1,500 for a larger Victorian or Edwardian style, with a 10-year guarantee on Kolorbond-certified work.

What Can Be Sprayed on a Conservatory?

Every uPVC frame component can be sprayed: the wall frames, door frames and door panels, the eaves beam where the roof meets the walls, the fascia sections and the ridge capping along the top of the roof. These are the same material as uPVC windows and take the same process as our uPVC window and door spraying.

The glazing units and polycarbonate roof panels cannot be sprayed. They do not accept the adhesion primer and topcoat, and painting them would not give a usable result. If polycarbonate panels are yellowed or cracked, replacing those sections is the right fix.

In practice, a conservatory respray covers all the white plastic you see from outside: the frames, the door, the eaves and the ridge. On an older conservatory that is usually the most dated-looking part, and changing it from white to anthracite grey or another colour changes the whole structure.

The Process for Conservatory Spraying

The process follows the same stages as windows and doors: clean and degrease, apply a specialist uPVC adhesion primer, spray two coats of Kolorbond-certified topcoat with HVLP equipment, remove the masking and inspect the finish with you. What makes a conservatory different is access and masking.

Masking takes longer than on a window. Every glass panel, polycarbonate sheet, the brickwork, paving and anything nearby is fully protected before any coating is applied.

Access Requirements

The lower frames and door of most conservatories can be reached from the ground or a hop-up platform. The upper frames and eaves beam on taller conservatories need a step ladder or a scaffold tower for a stable working platform.

The ridge on a pitched roof usually needs a lightweight scaffold tower. We organise it as part of the job and include it in the fixed-price quote, so it is not added at the end. On a lean-to with a shallow mono-pitch roof, the top edge is often reachable from a step ladder. We assess access at the free home visit.

Cost: What to Expect

Price depends on the size and style of the conservatory, the condition of the frames and the access needed. These are typical ColourHaus prices for conservatory work:

Conservatory type	Typical price
Small lean-to (up to 3m x 3m)	£400 to £600
Standard lean-to (3m x 4m to 4m x 4m)	£500 to £800
Victorian or Edwardian style (larger footprint, pitched roof)	£700 to £1,200
Large Victorian or Edwardian needing scaffold access	£900 to £1,500

Prices are fixed and agreed before work starts, and 0% finance is available. Spraying the house windows (from £80 to £150 each) at the same time costs less than booking the two jobs separately. If the walls or render around the conservatory need refreshing too, our exterior spraying service can be quoted alongside after a survey.

How Long Does a Conservatory Respray Last?

Conservatory frames face the same UV, temperature swings and rain as your windows, and they get the same coating. uPVC sprayed with Kolorbond-certified coatings carries a 10-year written guarantee from ColourHaus covering colour stability and adhesion. How long it lasts beyond that depends on exposure, colour and cleaning. Our guarantee page explains what it covers.

The ridge and eaves get slightly more sun on a south-facing conservatory, which is within what a UV-stable uPVC coating is designed for. Look after the frames as you would windows: warm soapy water and a soft cloth, no abrasive cleaners and no pressure washer aimed at the joints.

Colour Choices for Conservatories

The most common choice is RAL 7016 Anthracite Grey to match the house windows, so the conservatory reads as part of the house rather than an add-on. If you are deciding between greys, our guide to anthracite grey uPVC windows compares RAL 7016, 7021 and 7024.

• RAL 7016 Anthracite Grey. Matches most grey windows and gives a contemporary, unified exterior.
• RAL 9005 Jet Black. A stronger, more dramatic option, particularly against stone or render.
• RAL 6005 Moss Green. Links the conservatory to the garden; works well on rural and semi-rural houses.
• RAL 9001 Cream. For refreshing yellowed or chalky white uPVC with a clean, warm finish instead of changing colour.

We show sample panels at the home visit so you can see them against your brickwork and garden. To match an exact colour on the house, use our colour matching service. For the full range of possible colours, see what colours you can spray uPVC.

Conservatory Spraying vs Replacement

Replacing a conservatory, or even just its uPVC frames, costs many times more than spraying and involves building work. If the structure is sound and the glazing is intact, spraying the frames for £400 to £1,500 gives the visual change for a fraction of that.

Replacement makes sense when the structure has problems, the roof system has failed, you want a different size or design, or the conservatory is simply too old to be worth investing in. If none of those applies, spraying is the practical choice. For the bigger picture across windows, doors and frames, see our complete guide to uPVC spray painting.
