House Extensions in Aylesbury | Aylesbury Decorators
Aylesbury Decorators provide house extension decorating services across Aylesbury and the surrounding Vale — finishing after the shell is built and matching new rooms to the existing property.
What we cover:
- Decoration for single-storey and two-storey extensions after the shell is built
- Mist coat application on fresh plasterboard and coordination with your builder
- Matching new extension finishes to your existing rooms
- Full one-stop project coordination with local building trades we have worked alongside for years
Aylesbury Decorators work with local builders and building trades we have worked alongside for years across Bedgrove, Watermead, and Buckingham Park to deliver decoration as part of a wider extension build. Our role is finishing after the shell is built. We coordinate decoration specification with the plasterer before the skim dries rather than inheriting a mismatch when the build hands over.

Why Choose Aylesbury Decorators
Extension-Junction Experience
Matching new extension finishes to existing rooms is a coordination task as much as a decorating one. We agree mist coat sequencing, primer selection, and finish coat systems with the plasterer before the plaster is dry.
Contractor Network
We work with local builders across Bedgrove, Watermead, and the wider Aylesbury Vale who handle the structural build. Our decoration specification is agreed upfront so there are no surprises at handover.
Fully Insured
Full public liability cover on every extension decoration project, residential and commercial.
Word-of-Mouth Led
Most of our extension work comes from repeat clients and builder referrals across the Vale of Aylesbury.
House Extension Decorating Services
Decoration for Single-Storey Rear Extensions
1960s–80s estate semis in Bedgrove and Watermead are the most common property type receiving single-storey rear extensions as owners upsize rather than move. Typically a new kitchen-diner opens into the original house through a knocked-through rear wall.
We work with the plasterer to agree the mist coat specification before the skim is dry. See our kitchen renovation page for kitchen-extension decoration scope.
Two-Storey Extensions and Loft Conversions
Two-storey extensions add bedroom and bathroom space above a ground-floor extension. We coordinate with the builder to ensure bathroom ceilings are primed with a moisture-resistant system before topcoat. Condensation above showers in a bathroom with standard emulsion causes early mould colonisation.
Loft conversions in Wendover and Stoke Mandeville often add sloping ceilings, Velux windows, and awkward junctions between original house structure and new plasterboard.
Matching New Finishes to Existing Rooms
The junction between old and new rooms is where finish mismatches become visible. Original plasterboard in a 1980s Watermead semi has aged for decades and carries a sheen level different from freshly skimmed board in the new extension.
Period cottages in Aston Clinton and Bierton often have original lime plaster meeting modern gypsum skim. For period-property substrate detail, see our period property painting page.
Coordination with Builders and Other Trades
House extensions involve multiple trades in sequence: bricklayer, roofer, plasterer, electrician, plumber, carpenter, and decorator. Decoration is the final stage after second-fix electrical and plumbing are complete.
For broader projects where the extension is one element of a wider programme across the existing house, see our home renovation page.

Here’s How It Works
1. Site visit and scope agreement
We visit the property and discuss the extension plans. If the build has not started, we review drawings and agree the decoration scope and handover sequence with the builder. If the build is underway, we assess the current stage.
2. Coordination with builder and plasterer
We agree the mist coat specification, primer system, and finish coat matching with the plasterer before the skim dries. This coordination stage is what prevents finish mismatches between new and existing rooms.
3. Substrate preparation after handover
We receive the extension from the builder once second-fix is complete and all dust-generating trades have finished. We assess plasterboard joints, corner beads, and skim quality. Any defects are flagged before decoration begins.
4. Mist coat and primer application
Fresh plasterboard receives a diluted mist coat to seal the surface. Once dry, we apply the matched primer system that brings the new surface to the same sheen and absorption rate as the existing rooms.
5. Finish coats
Two finish coats are applied with adequate drying time between each. We work across both the new extension and the adjacent existing rooms to ensure a seamless finish across the junction.
6. Final inspection
We check coverage, cut lines, and junctions in good light before closing the job. Touch-ups are completed on the day.
House Extension Decorating Costs in Aylesbury
Prices below are estimates only. Every property is different. Call 01296 938133 for a precise quote.
The decoration scope of a house extension in Aylesbury — mist coat, priming, finish coats on all new surfaces, and matching to existing rooms — typically costs between £5,500 and £11,000 depending on extension size and preparation complexity.
This is our decoration quote only. The contractor’s quote for the build itself (structure, roofing, glazing, first and second fix) is £30,000–80,000+, not ours.
Three factors set the decoration cost:
Extension size and room count
A single-storey kitchen-diner extension is a different scope from a two-storey extension adding two bedrooms and a bathroom. Floor area and ceiling height both affect the cost.
Junction preparation
Matching the new extension to existing rooms adds primer and coordination time. Properties where existing rooms also need refreshing extend the scope into a broader house painting programme.
Surface type in the existing house
Matching new gypsum plasterboard in an extension to original lime plaster in a period cottage requires more substrate assessment than matching new plasterboard to existing plasterboard in a modern semi.
Typical decoration ranges:
Single-storey rear extension, 1970s semi in Bedgrove (new kitchen-diner, mist coat, matched primer, two finish coats): £5,500–7,500.
Two-storey extension, 1980s detached in Watermead (ground-floor kitchen-diner plus first-floor bedroom and en-suite): £7,000–9,500.
Two-storey extension, period cottage in Wendover (mixed substrates, lime plaster to gypsum junctions, full coordination): £8,500–11,000.
