Decoration of offices, including buildings that stay occupied while the work runs.






GSD London is a specialist commercial painting and decorating subcontractor working for main contractors, quantity surveyors, property managers and private clients across London. Our office works cover decoration of commercial offices, including buildings that stay in use while the work runs, with phased floors and out of hours working. CHAS, Constructionline Gold, ISO 9001, ISO 14001 and ISO 45001.
Office painting is the decoration of commercial office space: open plan floors, cellular offices, meeting rooms, receptions, lift lobbies, tea points and WCs. Most office painting in London is carried out in buildings that stay in use, so the work is defined as much by the phasing as by the finish. Office painters and decorators zone the floor, work in the evening, overnight or at weekends, protect furniture and cabling at the start of each shift, and hand the area back clean before staff arrive.
The package usually sits inside a Category A or Category B fit-out, a landlord refurbishment of let floors, or a planned redecoration for a facilities manager. Low odour, fast curing water-based systems are specified so desks can be occupied the next day. GSD London delivers office painting across London for main contractors and fit-out contractors, priced from the specification, phased with the site team and signed off zone by zone.
Category B fit-out or a departmental move where the rest of the office keeps working. The decoration has to be zoned, worked out of hours and handed back clean each morning.
Dilapidations at lease end, or a landlord bringing a floor back to Category A for the next tenant. Both need a defined scope, a fixed programme and a clean handover.
Lobbies, lift cars, corridors and WCs are the first thing a visitor sees. Redecoration is planned around the building's hours so the entrance is never out of use.
New colours across every floor, usually on a fixed date. The work is phased so the whole estate changes over without closing any of it.
A managed office on a redecoration cycle, where the facilities manager needs one contractor, one RAMS and a programme that works around tenants.
Exposed soffits, ductwork and long ceiling runs are quicker and more even sprayed. It is planned in with the decoration so the floor is only released once.


We walk the floors with the site team, agree the phasing and set out which areas are handed back when.
Furniture and finishes are protected or moved, and access routes are agreed before each shift begins.
Preparation, making good and decoration are carried out within the agreed shift for that area.
Furniture is reinstated, the area is inspected with the site team and handed back ready for use.

View projectWe 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.
Yes. On occupied offices the work is phased and usually carried out in the evening, at night or at weekends. Each area is protected at the start of the shift, then cleared, cleaned and handed back before the following working day begins.
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.
This is agreed before the order is placed. We can move and reinstate loose furniture within the working area as part of our package, or work around it where the client prefers. Either way it is set out in writing so there is no gap in scope.
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.

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
