Where’s the job?

Scope of Works

• Remove existing window frame and glazing carefully, salvage parts if requested

• take accurate opening measurements and confirm reveal, cill and DPC levels before ordering

• supply and fit new window (uPVC, timber or aluminium) with double or triple glazing, seals and trickle vents

• fit locks, handles, beads and internal trim; foam and silicone externally to make weather‑tight

• make good plaster and pointing around the reveal (minor making good included; full decoration is extra)

• clear site and dispose of old frames and broken glass safely; operatives will use PPE and dust protection

Typical Cost

Time on Site

Most single window replacements take 2–4 hours on site; an upstairs bay or bespoke unit can take a full day and may need scaffold. Factors that extend time include rotten reveals, bespoke manufacturing lead times, additional making good, and poor access

Questions to Ask Your Tradie

• will you register the work with FENSA/Certass or provide building‑regs certification

• what guarantee do you offer on frames and sealed units and what does it cover

• will you supply a written quote showing materials, labour, disposal and any scaffold costs

• who is responsible for making good plaster and decoration and is that included

• do you expect to need scaffold or a tower and how will you manage permits/parking for it

• how long is the lead time for the units and what happens if glass is damaged in transit

How to Avoid Surprises

• ensure clear access and book parking or a loading bay close to the work area

• remove curtain poles, blinds and fragile items from the working area beforehand

• check if the property is in a conservation area or has planning restrictions before ordering bespoke frames

• arrange for children and pets to be kept away during removal and glazing for safety

• confirm who provides and pays for scaffolding, permits and any neighbour notifications

• agree in writing what making good includes and whether decoration is part of the price
