Looking for sash windows in Wembley? International Windows Group manufactures and installs bespoke timber and uPVC sash windows across Wembley, Wembley Park, Wembley Central, Sudbury, North Wembley and surrounding HA0 and HA9 postcodes. Every window is made to measure in our own workshop and fitted by our installation teams — from single window replacements in inter-war semis to complete re-fenestration projects in larger Wembley properties.
Whether you’re upgrading drafty single-glazed windows in a 1930s semi, replacing failed double glazing in a modern build, or restoring sash windows in older Wembley properties, our solutions combine traditional sash window operation with modern thermal and acoustic performance. Free survey, 4 weeks lead time after deposit, full installation included.
Why Choose Bespoke Sash Windows for Wembley Homes
Wembley has a varied housing stock — from Victorian and Edwardian properties in older parts of the area, to extensive inter-war semi-detached and terraced housing built between the 1920s and 1950s, to modern developments around Wembley Park and the regenerated stadium district. Each property type has different sash window requirements, and our made-to-measure approach means every installation suits your specific property style.
Inter-war Wembley properties were typically built with timber casement or basic sash windows that have long since reached end of life. Replacing these with modern bespoke timber sash windows — or low-maintenance uPVC alternatives — significantly improves thermal performance, reduces external noise, enhances security, and increases property value. For period homes in older Wembley streets, timber remains the most appropriate material for maintaining architectural character.
We work across all Wembley postcodes including HA0 (Sudbury, North Wembley), HA9 (Wembley Central, Wembley Park, Tokyngton) and neighbouring areas. Same workshop, same installation teams, same quality standard for every project.
Our Sash Window Range for Wembley Properties
Timber Sash Windows
Our bespoke timber sash windows are the natural choice for older Wembley properties and homeowners who want premium quality and authentic appearance. Manufactured in Accoya, European Redwood or Engineered Hardwood, with double or triple glazing, traditional ironmongery and factory paint finish.
Browse our complete timber sash windows range for technical specifications and examples in our timber windows portfolio.
Best for: Period properties, owners prioritising authenticity, properties needing planning approval.
uPVC Sash Windows
For 1930s semis, modern Wembley properties and homeowners prioritising low maintenance, uPVC sash windows replicate the look of traditional timber with all the maintenance benefits of modern materials. Foiled finishes can mimic painted timber or natural wood grain, with identical mechanical operation to weighted timber sashes.
Best for: Inter-war semis, modern properties, landlords, owners wanting maintenance-free windows.
Double Glazed Sash Windows
Standard specification for new sash window installations in 2026. Modern slim-profile double glazed units deliver U-values from 1.4 W/m²K — transforming thermal performance for older Wembley properties without changing the external appearance. For homes near the busy roads around Wembley Stadium or the North Circular, acoustic glazing significantly reduces traffic noise.
Compare glazing options in our guide to double vs triple glazing in London.
Best for: All Wembley homeowners looking to reduce heating bills and external noise.
Casement Window Alternative
If you’re considering alternatives to sash windows, our timber casement windows are particularly suited to inter-war Wembley properties where casements may be more appropriate than sashes architecturally.

Our Process for Wembley Installations
1. Free Survey
A specialist visits your Wembley property to measure each opening, assess existing window condition, and discuss specification options. The survey typically takes 60-90 minutes and includes a detailed conversation about timber vs uPVC, glazing choices, finishes and any access considerations.
2. Written Quotation
Within 5 working days you receive a detailed written quote with each window itemised — frame specification, glazing, ironmongery, finish and installation. No hidden extras, no aggressive sales follow-up. Request our product brochures to review specifications in detail.
3. Manufacturing
Once you confirm the order and pay the deposit, manufacturing begins in our workshop. Lead time is 4 weeks for standard specifications, 5-6 weeks for complex bespoke orders.
4. Professional Installation
Our in-house teams remove existing windows, install the new units, make good internal and external reveals, and complete final adjustments. A typical Wembley semi with 8-10 windows takes 3-4 days. We carry full liability insurance and clean up daily.
5. Aftercare
Every installation includes a 10-year manufacturer warranty on frames, 5-year warranty on installation workmanship, and 10-year warranty on glazing units. Compliance documentation is available on our certificates page.

Frequently Asked Questions
How much do sash windows cost in Wembley?
Sash windows in Wembley range from £700 per window (uPVC) to £2,400 per window (premium Accoya timber), with full house replacement projects typically costing £8,000-£20,000 depending on size and specification. Use our cost calculator for a precise estimate.
Do I need planning permission for sash windows in Wembley?
Most of Wembley is not in a Conservation Area, so like-for-like sash window replacement usually falls under permitted development. If your property is in a specific Conservation Area or is Listed, planning permission may be required. We can advise during the free survey.
Should I choose timber or uPVC sash windows for my Wembley home?
For period properties (Victorian, Edwardian, older Wembley streets), timber is the more appropriate choice both visually and for property value. For inter-war semis and modern properties where maintenance is the priority, uPVC offers excellent value with identical mechanical operation. We discuss the best option for your specific property during the survey.
How long does installation take in a typical Wembley semi?
A standard Wembley semi-detached property with 8-10 windows takes 3-4 days for full installation. We complete one or two rooms per day so your home remains liveable throughout the project.
Can sash windows reduce noise from the North Circular or Wembley Stadium events?
Yes. Modern double glazed sash windows significantly reduce external noise compared to single glazing. For properties near major roads or event venues, our acoustic glazing options provide enhanced sound insulation.
Do you offer a guarantee on sash window installations?
Yes. Every installation comes with a 10-year manufacturer warranty on the timber frames, 5-year warranty on installation workmanship, and 10-year warranty on the sealed glazing units.
