Painting and decorating on commercial projects across London, delivered to the main contractor's programme.






GSD London is a specialist commercial painting and decorating subcontractor working for main contractors, quantity surveyors, property managers and private clients across London. Our commercial works cover painting and decorating on new build and refurbishment projects, priced from the specification and delivered to the agreed programme. CHAS, Constructionline Gold, ISO 9001, ISO 14001 and ISO 45001.
Commercial painting and decorating is the preparation and finishing of walls, ceilings, joinery and metalwork in buildings that are built, run or let as a business: offices, schools, hospitals, hotels, retail, residential blocks and public buildings. It differs from domestic decorating in scale, in contract, and in how the work is run. A commercial painting contractor prices from a specification and drawings, works under a JCT subcontract to a main contractor's programme, and hands over areas that have been inspected and signed off, with the product data and warranties the building file needs.
In practice the package covers new build decoration for handover, refurbishment of occupied buildings, common parts and communal areas, and specialist coatings where the specification calls for them. Preparation and making good take most of the labour. The finish is judged at the junctions: skirting to wall, frame to plaster, new work to existing. GSD London delivers commercial painting and decorating across London as the finishing trade on live sites, with RAMS for every package and each area protected, decorated and handed back in sequence.
Plaster is drying, second fix is going in and the programme needs a decorator who can follow the trades floor by floor and finish clean for the client walk-round.
The specification calls for preparation, making good and a set number of coats across common parts, cores and let space, priced against drawings and a schedule of areas.
Offices, schools, hospitals or housing that cannot close. The job needs zoning, out of hours working and handback at the end of every shift, not just a good finish.
Decoration, spraying, fire protection and window repair under one order, one set of RAMS and one site contact, rather than four trades to coordinate.
A managed building on a five or seven year redecoration cycle, where the work has to be programmed around tenants and finished to a standard the managing agent can sign off.
Flaking, staining or poor adhesion on an existing scheme. The cause has to be found before the surface is redecorated, or the failure comes back.


We review the drawings and specification, price the works and agree the sequence with the site team.
Floors and finishes are protected, and access is agreed with the main contractor before work starts.
Surfaces are prepared, made good and decorated in the coats set out in the specification.
Each area is inspected with the site team, snags are closed out and handover records are issued.



We work as a subcontractor to the main contractor or for private clients. The order sits under JCT subcontract terms or individual contracts with clients. Site rules, access, welfare and the programme are set by the main contractor, and our works are planned around the sequence already agreed on site.
Coats follow the specification issued with the enquiry, usually preparation, a mist coat where required, and two finish coats. Where the specification is silent we set out what we have allowed in our price, so submissions can be compared on the same basis.
Pricing follows the drawings, the specification and the schedule of works issued with the enquiry. Where the scope is not yet fixed we price on a provisional basis and confirm it once the survey is complete. Variations are agreed in writing before the work is carried out.
Yes. Where a benchmark is required we prepare a sample panel or a complete room for approval before the wider works proceed. The approved area is retained on site and used as the standard the rest of the package is inspected against.
Each area is inspected with the main contractor site team before the protection comes down. Snags are recorded and closed out in the same visit where possible. Handover records, warranties and product data sheets are issued together as part of the completion pack.
We take immense pride in our distinguished clientele, a testament to the unwavering quality and excellence that defines GSD London. From heritage to prestigious businesses, our reach spans across the vibrant tapestry of London.

GSD has undertaken numerous projects for Quinn over the past few years, including flagship projects for the V&A Museum and Warburg Institute both in the range of circa £300,000. Happy to recommend.

GSD completed the communal redecoration package valued at £100,000 at the Marriott Mayfair Grand Residencies, a 5* hotel. The project was completed in a tight 12-week program with GSD working with us to deliver it to a high standard. There were several hurdles to overcome throughout the job due to client changes, but each change was dealt with professionally by the project team from GSD. After the contract completion, the client praised the attention to detail provided by GSD and their outstanding work ethic in meeting the high expectations/time constraints of the project
