Glass replacement and heritage glazing, delivered as a subcontractor to the main contractor.
GSD London is a specialist commercial painting and decorating subcontractor working for main contractors, quantity surveyors, property managers and private clients across London. Our glazing works cover glass replacement and heritage glazing, delivered alongside window repair or as a package in its own right. CHAS, Constructionline Gold, ISO 9001, ISO 14001 and ISO 45001.
Commercial glazing, in the sense GSD London offers it, is glass replacement and reglazing in existing windows on commercial, public and heritage buildings: removing cracked, broken or failed panes, preparing the rebate, and fitting and sealing replacement glass to match the original or to the specification. It covers single glazing, heritage and sash window glazing with putty or beads, safety glass where the location requires it, and slim double glazed units where the joinery and the listing allow.
The work is usually delivered alongside window repair, because failed putty is the most common reason a sash decays, but it can also be a package in its own right on a refurbishment. Each pane is surveyed and scheduled so the price and the inspection are built on the same document. GSD London carries out glazing and glass replacement across London for main contractors, in occupied buildings and out of hours where the programme needs it.
Storm damage, impact or age. Panes are measured, matched and replaced, with the opening made weathertight in the same visit where possible.
Loose glass and water getting into the rail. Re-puttying and reglazing protects the joinery as much as the glass.
Sash overhaul and timber repair usually disturb the glazing. Doing both under one order means one survey, one schedule and one sign-off.
Doors, side panels and low-level glazing must meet current safety glazing standards when replaced. The survey identifies which panes.
On a listed building the conservation officer may want drawn or crown glass kept or matched. We record what is there and source to match.
Slim double glazed units can sometimes go into existing rebates. The survey confirms whether the joinery and the listing allow it.
We attend site, measure each opening and record the glass type, condition and the access required.
Floors and finishes are protected and access is agreed with the main contractor before work starts.
Glass is removed, the opening is prepared, and the replacement unit is installed and sealed.

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.
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. On occupied buildings the work is usually phased, with evening, night or weekend shifts agreed in advance. Access, protection and containment are set up and removed within each shift, so the space is handed back in use at the start of the next working day.
Floors, finishes and adjacent surfaces are protected before any glass is removed. Access equipment is agreed with the main contractor in advance. Removed and broken glass is bagged, stored and taken off site under the site waste procedure, and the working area is cleared at the end of each shift.
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
