When planning window replacement or restoration projects, understanding wooden sash windows price ranges is crucial for making an informed decision. Timber sash windows remain a popular choice for period properties, conservation areas, and modern homes seeking authentic character combined with contemporary performance.

This guide breaks down the cost factors, benefits, and pricing considerations to help architects, developers, housebuilders, and homeowners budget effectively for their sash window projects.

Why do wooden windows cost more than uPVC or aluminium?

Wooden windows cost more than uPVC or aluminium because they use premium timber materials that are significantly more expensive than synthetic alternatives. Manufacturing also requires skilled craftsmanship and specialised joinery experience compared to other materials. Timber windows are typically made-to-order with custom sizing and bespoke detailing.

Skilled craftsmanship

Manufacturing timber sash windows demands years of experience and specialised knowledge. At Lomax + Wood, each of our windows requires precise joinery, careful timber selection, and meticulous attention to detail that machine-made alternatives cannot match.

Premium materials

Quality timber costs significantly more than synthetic materials. Whether working with Redwood, Oak, or Accoya, all of our timbers are sustainably sourced. We are proud of the fact that every piece of timber used in our made-to-order timber windows is FSC® or PEFC certified. Unlike other sustainability credentials, our full Chain of Custody certification guarantees complete traceability throughout the supply chain, ensuring that our timber comes from forests that are sustainably managed.

Bespoke manufacturing process

Unlike standard sizes available for uPVC windows, timber sash windows are typically made-to-order. This customisation ensures perfect fit and authentic period detailing but requires individual attention throughout the manufacturing process.

Performance and authenticity: why choose timber?

Authentic aesthetic appeal

Timber offers unmatched visual appeal, particularly crucial for older buildings and conservation areas. The natural grain, texture, and ability to accept various finishes create character that synthetic materials cannot replicate.

Superior performance

Modern wooden sash windows like ours at Lomax + Wood deliver excellent energy efficiency with U-values as low as 1.1 W/m²K. Combined with quality double glazing, they provide better insulation than many assume, helping reduce energy bills over time.

Flexibility and repairability

Unlike uPVC windows that require complete replacement when damaged, timber allows for minor repairs and restoration. Sash window repair costs are often significantly lower than full replacement, making timber a practical long-term choice.

The long-term value of timber windows

While the initial cost may be higher, timber sash windows prove to be a worthwhile investment. Quality wooden windows can last decades with proper maintenance, often outliving cheaper alternatives that require replacement every 15-20 years.

Authentic timber sash windows add considerable value to period properties and newer homes alike. This is particularly important in conservation areas where planning requirements favour traditional materials.

Are timber sash windows high maintenance?

While timber windows have gained a reputation as being high-maintenance, modern timber treatments and finishes mean today’s wooden sash windows require surprisingly low maintenance. Quality factory-applied microporous paints and advanced timber treatments significantly reduce maintenance costs compared to older systems.

Cost variables: what affects sash window pricing

Window Size and Configuration

Larger windows naturally cost more due to increased material and labor costs. Georgian sash windows with multiple glass panes require more intricate glazing work, affecting the overall cost.

Timber species

• Engineered Redwood: Most cost-effective option
• Engineered Hardwood: Mid-range pricing
• Oak: Premium pricing as a slow-growing timber species
• Accoya: Highest cost but exceptional performance

Glazing options

• Single glazing: Lowest cost, suitable for listed buildings but limited thermal performance
• Double glazing: Standard choice balancing cost and performance
• Triple glazing: Premium option for maximum energy efficiency

Installation complexity

Professional installation costs vary based on:

• Accessibility of windows
• Extent of the damage to existing frames
• Structural modifications required
• Number of windows being replaced
• Heritage building constraints

Bespoke detailing

Georgian bars, specific ironmongery, custom colours, and period-accurate profiles all influence the total cost. However, these details are often essential for planning approval in conservation areas.
