A family firm in Tonbridge. Survey, fitting and making good are all done by our own people — the job does not get handed to a crew we have never met.
We come out, measure the openings and tell you straight what is worth doing and what is money down the drain.
No subcontractors. Three teams, here nine years on average.
Reveals, sills, sealant and taking the old frames away are in the price, not added at the end.
Windows settle over the first winter. We come back and adjust them, and there is nothing to pay for it.
Put in the sizes and what you want. It works out a guide price per window including fitting and taking the old one out, the U-value for the whole window, and a rough figure for what it saves on heating. Add as many windows as you need — one click puts the list into the enquiry form.

How this is worked out. Prices are what this sort of work costs in the south east in 2026 and include VAT at 20% — replacement glazing does not qualify for the zero rate on energy-saving materials, whatever anyone tells you. The U-value is worked out by area to BS EN ISO 10077-1, from the real split between glass and frame, which is why a small window comes out worse than a big one with the same glass. The saving uses degree days (about 2,100 for the south east) against an older double-glazed unit at U 3.1, with 20% knocked off for solar gain and the heating being off part of the time, at 6p a kWh of gas.
And to be blunt about it: windows do not pay for themselves out of the heating bill — on a normal house it is well over twenty years. They are worth doing because the house is warmer and quieter, because it stops draughting at the sill, and because you can actually lock them. The firm price comes after the survey; the guide figure is for white uPVC (a coloured foil is about 12% more) and fitting at ground or first floor without scaffolding.
Windows, doors and blinds get done as one job. Buy the windows from one firm and the blinds from another and you end up refereeing an argument about whose fault the reveal is.
Windows
From a six-chamber uPVC profile for a normal house to aluminium for big glazed openings.
Doors
Front doors come with the threshold, the handle and the lock sorted. PAS 24 is standard here, not an upgrade.
Blinds
External shading on the south side, inside blinds are plenty on the north. The advice follows which way the window faces, not the price list.
A normal houseful of windows takes about six weeks, and we are in your house for two of those days.
Ring or send the list from the calculator. We come back to you by the next working day.
within 24 hoursThe surveyor measures the openings, checks the sills and the lintels, and goes through colours and handles with you.
free, 30–60 minutesThe windows are made to your sizes, and we fit them to BS 8213-4 into a properly sealed joint.
4–6 weeks + 1–2 daysWe make good the reveals, fit the sills, hoover up, adjust the hardware and hand you the FENSA certificate and the guarantee.

The FENSA certificate arrives without you chasing it. Replacement windows have to be signed off under Building Regulations. We do it through FENSA and the paperwork reaches you within three weeks — the certificate your solicitor will ask for when you sell.
The price on the survey is the price on the invoice. If we find rot in the lintel or a sill that has gone, we ring you before touching it and tell you what it adds. Nothing gets discovered on the last day.
We come back after the first winter. Frames settle and hinges need a turn. We book it in ourselves, we do it for nothing, and it is not something you have to remember to ask for.
Roughly how many windows and where you are is enough. We come back by the next working day and book the free survey.
