Decoration Scope on a New Extension
Fresh plasterboard needs a sealing coat before any finish coat goes on. New wet-plastered walls need a full cure period before primer is applied — without it, neat emulsion soaks into the board face unevenly and joint lines remain visible.
Our decoration quote covers our element of the project. The contractor’s quote covers the structural build — groundworks, brickwork, roof, glazing, and first-fix trades.
Contractor-Partner Framing
Rear and side-return extensions in Slough are heavily driven by multi-generational household demand. The extension itself is a building project; the finish is ours.
If you need roofing, brickwork, new windows, carpentry, flooring, electrical, or plumbing work, we can refer you to contractors with whom we have a working relationship. For broader refurbishment context, see our home renovation page.
Sequencing After First and Second Fix
Plasterboard must be taped and skimmed. Wet render or plaster needs four to six weeks of drying time in reasonable conditions before primer goes on. Second-fix joinery and skirting land after our first decoration pass.
Returning to the extension for a second pass after second-fix work lands is standard — we account for this in the programme from the beginning.
Original-to-Extension Junction
Where a new extension opens into the original house, the surfaces at the threshold are different. Existing room carries original plaster in aged condition; the new extension is plasterboard or fresh render.
We use different primer systems at each surface and manage the junction so both sides read at the same sheen level after finishing.
Kitchen Extensions
Where a rear extension creates a new kitchen-diner or extends an existing kitchen, the decoration scope overlaps with a kitchen renovation. New walls and ceiling in the extension, matching into existing kitchen finishes, and working around the unit fitter, tiler, and electrician — all of this is part of the extension decoration programme.

Here’s How It Works
1. Site Visit Before Builder Sign-Off
We visit the extension space before decoration starts, sometimes while the build is still active. We assess which surfaces will be ready and when, and agree the programme with you and the main contractor.
2. Conditions Check
Before any primer goes on, we verify that plaster and render have cured sufficiently. We check for any areas where first-fix trades have left surfaces that need attention before decoration can proceed.
3. Sealing Coat on New Surfaces
Fresh plasterboard gets a diluted sealing coat before any finish coats go on. New plaster gets the correct primer for the surface type. These steps are not optional — they determine whether the finish holds over the first heating cycle.
4. Junction Management
Where the extension meets the original house, we apply different products to each surface and manage the transition across multiple coats. The goal is a consistent finish across the threshold.
5. Second-Fix Return and Final Walkthrough
After second-fix trades have finished, we return to complete skirting, architrave, door, and window board decoration. We go through the full space with you before sign-off.
House Extension Decoration Costs in Slough
Costs vary across Slough’s diverse stock; figures below are starting ranges. Call 01753 303456 for a free quote.
The full build cost of a rear or side-return extension in Chalvey or Cippenham typically runs from GBP 30,000 to GBP 80,000 or more — that is the contractor’s element. The decoration and finishes scope is typically GBP 6,000 to GBP 12,000 depending on floor area, ceiling complexity, and finish specification.
Floor Area and Room Count
A single-storey kitchen extension is a smaller decoration programme than a two-storey side return adding a bedroom and a bathroom above a ground-floor living space. Floor area drives the timetable.
Junction Complexity
Where the extension connects to the original house through a wide opening, the junction between old and new surface is longer. More junction length means more time spent managing the transition between primer systems.
Finish Specification
Standard matt emulsion on walls and ceilings costs less than a full woodwork programme covering skirtings, architraves, doors, and window boards in oil-based finish throughout.
Trade Insight
Extensions in Cippenham and Langley that open an original kitchen into a rear lean-to always carry a substrate junction. Budget for mixed-substrate treatment rather than assuming uniform wall conditions.
Typical ranges: single-storey rear extension decoration, Chalvey or Cippenham, GBP 6,000 to GBP 8,500; two-storey side return decoration, Upton or Langley, GBP 8,000 to GBP 12,000; loft conversion decoration, Wexham or Burnham, GBP 5,000 to GBP 8,000.
