Windows and doors packages
Aluminium windows, bifold, sliding and entrance doors, supplied and installed plot by plot or floor by floor.

Flats and commercial buildings
Flats, offices and commercial premises, priced from the tender documents.
What people worry about, answered plainly
“We need a glazing price that doesn't move after award.”
We price from your drawings, window and door schedule and specification, and ask about anything unclear before we submit rather than price on a guess.
“Our programme depends on windows arriving when promised.”
Orders are placed to suit your programme and lead times are confirmed at order. We survey the built openings first, so frames fit the building as built.
“Chasing a supplier and a separate fitting gang wastes time.”
We supply and install, so there is one contractor and one point of contact on site when a snag needs sorting.
“Every plot or floor needs the same standard.”
Using the same systems across a development keeps sightlines, finishes and hardware consistent from plot to plot, and our installers fit to the same standard throughout.
Drawings, schedule and spec are enough to start.
We aim to reply the same working day to confirm we have them.
Commercial window installers, from tender to handover
How a package runs with us, and what we need from you at each point.
-
1. Send the documents
Drawings and elevations, the window and door schedule, the specification, the programme and a site contact. Part of the package is enough for an early view.
-
2. Survey the built openings
On award we measure on site, because a frame made to the drawing does not always fit the opening as built.
-
3. Fit plot by plot
Our installers fit plot by plot or floor by floor, and you raise any snag with us directly.
Trickle vents and escape hinges are specified to Building Regulations, and glass and hardware follow your specification.

Installation
Our installers fit the windows and doors plot by plot or floor by floor, and we deal with any snags directly.
10-year installation guarantee
Commercial aluminium windows and doors for new builds, flats and commercial buildings are a large part of the work we do. We supply and install for developers and main contractors across London, inside the M25 and in surrounding areas, working from our base in Hayes. Send us the drawings, window and door schedule and specification, and we will price your tender.
Supply and fit for developers and main contractors
On a development, the glazing package touches everything: weathertightness, the programme, the finish buyers see on the show home. We take responsibility for both the supply and the installation, so there is one contractor to deal with from the first price to the last snag.
Our largest job so far is a new-build housing development near Guildford. We have also carried out commercial work for businesses. We will share project details and references with you directly where our clients have agreed.
Commercial glazing contractors for London and the South East
If you are looking for glazing contractors London projects can rely on, we cover all of London, inside the M25 and surrounding areas such as Surrey, Berkshire, Buckinghamshire and Hertfordshire. Being based in Hayes keeps west London, the M4 and the M40 close.
As commercial glazing contractors we focus on aluminium windows and doors: that is the package we price and install.
How we price a tender
We do not publish prices, and on commercial work a single figure would be meaningless. We price from your documents. The things that drive a commercial price:
- the number, size and type of openings
- the systems and finishes specified, including any special colours
- the glass specification
- hardware, vents and escape requirements
- access, storage and working at height on site
- the programme and how deliveries are phased
If anything in the specification is unclear, we come back with questions before we submit rather than price on a guess.
Lead times and programme
Lead times depend on the products and quantities in your package and on our availability, so we confirm them when orders are placed. Special powder-coat colours add 6 to 8 weeks, which is worth knowing at design stage if the architect has specified a non-standard finish. On homeowner orders, our bifold doors typically take about 10 working days and sliding doors 2 to 3 weeks from order, depending on availability, which gives a sense of how quickly standard items can turn round.
Send us your tender
Email or upload the drawings, schedule and specification through the quote form, or call to talk the job through. We aim to reply the same working day, Monday to Friday, 8am to 5pm. For product detail on the systems we fit, see our pages on aluminium windows, aluminium sliding doors and aluminium bifold doors.
Commercial glazing questions, answered
Not sure about something else? Send what you have and ask in the notes. We answer it with your quote.
Do you supply and install commercial aluminium windows?
We supply and install commercial aluminium windows and doors for developers and main contractors across London, inside the M25 and in surrounding areas. Our work includes new-build housing developments and commercial premises. We price from your drawings and schedule and our team installs.
How do you price a glazing tender?
We price from the drawings, the window and door schedule and the specification. The main drivers are the number and size of openings, the systems specified, the finish, the glass, the hardware, access and the programme. If anything in the spec is unclear, we ask before we submit rather than guess.
What do you need to price a tender?
Send the drawings and elevations, the window and door schedule, the specification for systems, finishes, glass and hardware, the programme or target start on site, and the site address with a contact for access. If you only have part of the package, send what you have and we will give you an early view, then firm up the price as the rest comes through.
What lead times should we plan for on new build windows?
Lead times depend on the products and quantities in the package and on our availability, so we confirm them when orders are placed. Special powder-coat colours add 6 to 8 weeks. We survey the built openings before ordering and plan deliveries around your programme.
Which areas do you cover for commercial work?
We take commercial and new-build work across London, inside the M25 and in surrounding areas such as Surrey, Berkshire, Buckinghamshire and Hertfordshire. We are based in Hayes, which keeps west London and the M4 and M40 corridors close.
Do you only supply, or do you fit as well?
Supply and fit is what we do on commercial work. One contractor responsible for the frames and the installation means one point of contact on site and no argument between supplier and fitter when a snag needs sorting.
