What we see in Greater London
The hard part of Sash Window Repair in Greater London is not the making, it is the measuring. The building stock is Victorian and Edwardian terraces, mansion blocks and post-war infill, so we expect variation before we ever pick up a tape. Set against high pollution load and sheltered urban humidity, most joinery here eventually shows paint failure on south-facing sashes and rot at the bottom rail. What you are paying for is saving the original timber wherever it is still sound.
Each opening is recorded individually, since a terrace of identical houses rarely is. A quick call or a photograph of the opening is usually enough to get you a price.
Local factor worth flagging early: large numbers of properties sit in conservation areas with like-for-like replacement conditions.

Do you cover Greater London?
Yes. We cover the whole of Greater London including Croydon, Bromley, Ealing, Enfield and the surrounding villages. Large numbers of properties sit in conservation areas with like-for-like replacement conditions. Because high pollution load and sheltered urban humidity, we allow for it at survey stage rather than discovering it on the day.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
Do you deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
