Beautifully Crafted Timber Sash Windows

Our bespoke wooden sash windows combine traditional craftsmanship with modern performance, making them the ideal choice for period homes, listed buildings, and character properties. Each sash window is made to measure using high-quality, sustainably sourced timber and finished to complement the unique style of your home.

From Georgian and Victorian properties to contemporary renovations, our timber sash windows are designed to preserve architectural character while delivering the insulation, security, and reliability expected from a modern window system.

At ERW, we have been manufacturing and restoring timber sash windows since 1979. Our experienced craftsmen combine traditional joinery techniques with advanced glazing and weatherproofing technology to create wooden sash windows that are both authentic in appearance and highly efficient in performance.

We manufacture sash windows using a range of premium timbers, including engineered timber, hardwood, and Accoya®, allowing us to recommend the most suitable material for your property's style, performance requirements, and long-term durability.

Whether you need brand-new sash windows or the refurbishment of existing timber frames, we provide bespoke solutions tailored to your property.

Frequently Asked Questions

Is it better to refurbish or replace sash windows?

If the original timber is structurally sound, refurbishment is often the most cost-effective and heritage-friendly option. Where windows are beyond economical repair, we can manufacture bespoke replacement wooden sash windows to match the original design.

How long does sash window refurbishment take?

The timescale depends on the number of windows and the extent of the work required. Many refurbishment projects can be completed within a few days, while larger restoration programmes may take longer.

Can broken sash window glass be repaired?

Yes. We can replace broken or damaged glazing while preserving the existing sash frame wherever possible.

Will refurbishment reduce draughts?

Yes. Professional draught proofing is one of the most effective ways to improve the comfort and energy efficiency of traditional sash windows.

Can listed building sash windows be refurbished?

Absolutely. Refurbishment is often the preferred approach for listed buildings because it retains as much original fabric and character as possible.

How much does sash window refurbishment cost?

Costs vary depending on the condition of the windows, the repairs required, and the glazing specification. We provide tailored quotations following a detailed assessment.

How long do refurbished sash windows last?

When repaired using quality timber and properly maintained, refurbished wooden sash windows can continue performing for many decades.

Can you improve energy efficiency without replacing the windows?

Yes. Draught proofing, glazing upgrades, and careful refurbishment can significantly improve the thermal performance of existing timber sash windows while retaining their original appearance.
