The Complete Timeline
| Stage | Duration | What Happens |
|---|---|---|
| 1. Design & quote | Same day | Use our 3D configurator to design and price your windows online. Instant budget price. |
| 2. Site survey | 1–2 weeks to book | We visit your property, take precise measurements, check structural conditions, and confirm the specification. |
| 3. Final quote | 2–3 days after survey | You receive a detailed quote based on actual survey measurements. No surprises. |
| 4. Production | 4–5 weeks | Your windows are manufactured in our UK workshop. Timber preparation, machining, assembly, glazing, and painting. |
| 5. Installation | 1–2 windows per day | Our FENSA-certified team removes old windows and installs new ones. Minimal disruption. |
| 6. Completion | Same day as install | Final adjustments, clean-up, and handover. FENSA certificate issued. |
For a typical London terraced house with 6–8 windows, the total timeline from first enquiry to completed installation is approximately 7–9 weeks: 1–2 weeks for survey and quoting, 4–5 weeks for production, and 3–4 days for installation.
What Can Cause Delays?
Planning Permission
Most window replacements do not need planning permission. However, if your property is in a Conservation Area or is a Listed Building, you may need consent before work begins. Conservation Area applications typically take 6–8 weeks; Listed Building consent can take 8–12 weeks. We can advise whether permission is needed during the survey stage.
Structural Issues
If the survey reveals structural problems — crumbling lintels, rotten sub-sills, damaged brickwork — these need to be addressed before or during installation. We flag these during the survey so there are no surprises on installation day.
Access and Scaffolding
Ground-floor and first-floor windows can usually be installed from ladders. Higher floors or difficult access may require scaffolding, which needs to be arranged in advance. We coordinate scaffolding as part of our installation service.
Bespoke Designs
Standard configurations (rectangular sash and casement windows) are delivered in 4–5 weeks. Arched windows, shaped frames, and other bespoke designs may require additional production time, which we confirm at the point of order.
How to Speed Things Up
- Use the configurator first — arrive at the survey with a clear idea of what you want. This eliminates back-and-forth on specifications.
- Book the survey early — survey slots fill up, especially in spring and autumn. Book as soon as you have a budget price you are happy with.
- Confirm quickly — once you receive the final quote, a prompt decision gets your order into production sooner. Every week of deliberation adds a week to your timeline.
- Check planning requirements early — if you suspect you need Conservation Area consent, start the process before ordering windows.
How Many Windows Can Be Installed Per Day?
A two-person installation team typically fits 1–2 full box frame sash windows per day, including removal of old frames, preparation of the opening, installation, sealing, and finishing. Casement windows are faster — 2–3 per day is typical. A terraced house with 6–8 windows takes approximately 3–5 days. Larger properties or those requiring structural work may take longer.
