Window Frame Painting Services
Timber Sash Frames
Timber sash windows in Caversham’s Victorian properties on Prospect Street and Church Road have accumulated paint layers over a century of use. The build-up causes sashes to stick in the frame and obscures the glazing bead detail.
We strip back where the build-up is excessive, back prime bare timber before it absorbs moisture, and apply durable exterior gloss or satin. Painted sashes are checked to slide freely before we leave.
Casement Windows
Casement windows in 1970s to 1990s properties in Earley and Woodley are often timber-framed and have been repainted multiple times. We check whether stiff casements are caused by paint build-up on the rebate or a timber swelling problem.
We advise honestly at the site visit if casements are beyond a painted repair. Where paint is the problem, thorough preparation and a careful topcoat resolves it.
uPVC Repainting
uPVC window frames can be repainted with specialist adhesion primers and compatible exterior finish coats. The surface must be cleaned, lightly abraded, and primed correctly for the new finish to adhere — without the right primer, paint applied to uPVC will peel within a year.
We advise on expected service life at the site visit. For uPVC in good condition, painting is a practical option.
Fascias, Soffits, and Sills
Timber fascias and soffits protect the roof line from water. We repaint timber fascias and soffits where they are sound and advise on replacement where they are not.
For the full exterior treatment including masonry walls and front door, see our exterior painting page.
Preparation and Priming
Back priming is the stage most often skipped on window frames, and the stage that most determines how long the finish lasts. We back prime every bare timber surface immediately after stripping.

Here’s How It Works
1. Window Frame Assessment
We inspect each window for paint condition, rot, sticking sashes, and paint build-up. We advise on stripping requirements and rot repair where needed.
2. Surface Preparation
Loose paint is removed. Heavy build-up in rebates and glazing bead channels is stripped back. Rot is cut out and filled with a specialist timber repair product where sound timber remains.
3. Back Priming
Any bare timber is back primed immediately to prevent moisture uptake. This stage is non-negotiable on exterior timber in the Thames Valley’s damp conditions.
4. Topcoat Application
One or two coats of exterior gloss or satin are applied. Sashes and casements are checked to open and close correctly after each coat. Final coat thickness is kept even to avoid running in the rebates.
5. Sash Check and Inspection
Sashes are checked to slide freely. All frames are inspected in good light. Any runs, missed edges, or bare patches are addressed before we leave.

Window Frame Painting Costs in Reading
Prices below are estimates only. Every property is different. Call 0118 230 8566 for a precise quote.

Window Type and Count
A property with twelve original sash windows costs significantly more than one with six modern casements. Each window type has different preparation requirements.
Modern casement windows in Earley or Woodley typically cost £80 to £140 per window for light preparation and two coats.
Paint Build-Up and Stripping
Windows with a century of paint build-up need considerably more preparation time than windows in good condition. Heavy stripping on a Victorian sash adds time but produces a result that works and lasts.
A Victorian sash window on Church Road in Caversham in stable condition typically costs £140 to £220 per window.
Timber Condition
Windows with rot require patching or partial replacement before any paint can be applied. We identify this at the site visit and quote it as a separate item.
Period cottages in Purley-on-Thames with heavy build-up typically cost £180 to £320 per window, including back priming. Call 0118 230 8566 to arrange a site visit.
