We offer a complete range of building services alongside our decorating work, delivered through trusted contractor partners. With years of experience in the SL6 catchment, we have built strong working relationships across the trades.
Our additional services through contractor partners include carpentry, flooring, electrical work, plastering, plumbing, roofing, and brickwork. You get a single point of contact and a coordinated programme rather than separate contractors managing their own timelines.
Decoration on a New Extension
A single-storey rear extension on a 1930s detached creates a new set of surfaces that need specific preparation before decoration. New plasterboard walls need a sealing board primer before any emulsion. Fresh plaster needs a mist coat before standard emulsion.
The junction between the new extension and the original property fabric requires individual assessment. These two surfaces need different primer systems. For the broader home renovation context, see our home renovation page.
Kitchen Extension Decoration
A kitchen extension combines the extension build with a kitchen fit-out. The decoration scope covers the new extension walls, the ceiling, and any original wall surfaces opened up as part of the knock-through.
For the full kitchen renovation decorating approach, see our kitchen renovation page. For the wider house painting programme if you are redecorating the whole property at the same time, see our house painting page.
Original-Fabric Junction Decoration
Opening up a wall between an existing room and a new extension exposes original fabric. Removed sections of plaster, bare brickwork reveals, and mixed surface conditions at the new opening all need assessment before decoration.
We stabilise, prime, and finish these junction surfaces as part of the extension decorating scope. The result is a consistent finish across original and new-build fabric with no visible junction line.
Here’s How It Works
1. Site visit and scope agreement
We visit the property and assess the full project — both the building work in scope with the contractor and the decoration scope we will manage directly. We provide a written quote covering the decoration. The contractor prices the building work separately.
2. Sequencing with the contractor
Decoration runs after first and second fix. We coordinate directly with the contractor’s project manager to confirm when plaster is dry and surfaces are ready. We do not start on surfaces that are not ready.
3. Board primer and mist coat
New plasterboard gets a board primer. Fresh plaster gets a mist coat. These steps are non-negotiable on new-build fabric and are included in every extension decorating quote as standard.
4. Junction preparation
Where new extension meets original property, we assess each surface individually, apply the correct primer, and ensure the finish reads consistently across the boundary.
5. Finish coats and final walkthrough
Finish coats run in the correct sequence. We walk through the completed decoration with you before closing the job.
House Extension Decorating Costs in Maidenhead
Costs vary across Maidenhead’s SL6 stock; the ranges below are illustrative — we quote each project from a site visit. The contractor’s quote covers the building work. Call 01628 965566 for a precise decoration quote.
Extension Size
A single-storey rear extension has a defined and compact scope. A two-storey rear addition with a loft conversion above has significantly more wall area and a longer programme.
Junction Complexity
Where new extension meets original property across multiple rooms, junction preparation takes more time. Mixed substrate boundaries require individual assessment and different primer systems.
Scope
Decoration-only quotes cover the extension fabric. Where the whole house is being redecorated at the same time, the programme expands accordingly.
Trade insight: a full two-storey rear extension on a 1930s detached in Furze Platt — structural build, roofing, windows, plumbing, and electrical — is a significant project.
