Your Lewisham postcode helps firms covering Greater London decide whether they can arrange the necessary visits.
Reasons to arrange an assessment
Explain what has changed and which openings are affected.
- Cracked frame joints, distorted profiles or other damage that cannot be put right by a repair.
- Old timber or metal windows being replaced with a suitable lower-maintenance system.
- A change to flush casements, tilt-and-turn or sash-style windows, where the property permits it.
- Poor closing and weather sealing that remain after repair options have been assessed.
Options to discuss at the survey
Compare the complete window rating, profile design, appropriate reinforcement and hardware rather than counting chambers alone. White casements, coloured foils and woodgrain sash designs can differ substantially in price. Tilt-and-turn windows open into the room and need clearance; their ventilation position should not be assumed secure unless the specific product is rated for that use.
Work to include in a written quote
- Measure openings and inspect existing subframes, cills and surrounding masonry.
- Prepare a room-by-room schedule covering frame finish, glazing, hardware and required escape openings.
- Protect the home, remove old frames and prepare sound fixings without concealing rotten timber.
- Install square and level frames with suitable support, then check closing pressure and lock engagement.
- Seal the perimeter, finish agreed trims and window boards, remove waste and explain maintenance.
Compare the scope as well as the cost
The indicative UK range for uPVC window replacement is £400–£8,000. The low end is for one basic casement; a multi-window order uses a much larger budget. Foiled sash windows, bays, bigger properties and difficult fitting conditions can exceed the range. Ask for opening-by-opening prices.
A property in Lewisham needs its own written quotation; the guide is not a fixed price. Confirm VAT where applicable, travel, safe access, waste removal and making good.
Before someone measures the job
State the number of windows, their current material and whether there are bays. Choose internal and external colours separately if you want a dual finish. Mention blinds, shutters, tiled reveals and any wish to replace the internal window boards.
Approximate sizes help with early discussions, but the supplier needs professional survey measurements before manufacturing.
Checks before committing to the work
For complete replacement windows, confirm the applicable energy, ventilation, safety-glazing and escape provisions with the installer. In England and Wales, an appropriate competent person scheme or building control can provide the compliance route; Scotland and Northern Ireland have separate arrangements. See government guidance on competent person schemes. A registered scheme is one route, not a blanket requirement to use a particular brand of scheme.
For a listed home or a restricted elevation, establish the permitted specification before paying a deposit. Ask Greater London Authority about the relevant local process. Leaseholders should also check any freeholder consent.
Fitting arrangements and aftercare
Ask how old uPVC will be separated for recycling where facilities allow. Follow the supplier's cleaning and lubrication instructions, and keep drainage and ventilators unobstructed. Check guarantee terms for foil finishes as well as frames, glass and hardware.
Allow for the gap between the measuring visit and fitting; made-to-size products must be ordered first. The site's guide fitting time is 1–3 days, depending on scope and access.

Answers for homeowners in Lewisham
How can I request uPVC window replacement quotes in Lewisham?
Use the free enquiry form to give your postcode and describe the affected windows or doors. Double Glazing Quotes can introduce up to four independent uPVC window installers covering Lewisham, depending on service coverage and availability. You do not have to accept a quotation.
Can I choose a different finish inside and outside?
Many systems offer dual-colour finishes. Confirm the exact foil or colour on each face, including exposed edges, before approving the order because availability and lead times vary.
Does every uPVC window contain steel reinforcement?
No. Reinforcement depends on the system, window size, colour and design. Ask the supplier to confirm that the proposed window meets its system requirements and stated performance.
Does condensation mean I need new uPVC frames?
No. Condensation can have several causes. Assess ventilation, indoor moisture and glass condition before deciding whether frames need replacement.
