Timber Window Costs: A Trade Professional's Guide to Material Selection

Last Updated: 28 October 2025

When specifying timber windows for your construction projects, understanding the cost of timber windows is essential for accurate budgeting and customer discussions. As experienced joiners, we know that the final price of bespoke wooden windows depends on multiple factors, with timber selection being one of the most significant.

Key Factors Influencing Timber Window Costs

The investment in quality timber windows varies considerably based on several elements. Some things to consider when drawing up a quote for timber windows include the following points.

Timber Species Selection

Different wood species come with varying price points, each offering unique benefits:

  • Premium hardwoods (Oak, Sapele) – medium priced
  • Modified woods (Accoya) – most expensive

Although modified timber is usually the most expensive option, it can often outperform hardwood in terms of both appearance and performance.

Window Design Complexity

The architectural design significantly impacts manufacturing costs. Some timber window designs to consider include:

  • Traditional sash windows
  • Casement configurations
  • Bay window arrangements
  • Customised shapes and sizes

The more detailed and bespoke your timber windows, the higher the costs will usually be.

Understanding Material Choices

Accoya: The Modern Choice

While initially more expensive than some hardwoods, Accoya offers:

  • Extended lifespan
  • Reduced maintenance requirements
  • Superior stability
  • Enhanced durability

Traditional Hardwoods

Natural hardwoods present different cost considerations including:

  • Variable availability affecting pricing
  • Species-specific durability
  • Natural resistance properties
  • Aesthetic appeal

The unique appearance of specific hardwoods means that they will be particularly suited to certain installations.

Long-term Cost Implications

When evaluating timber window costs, it’s important to think about the overall cost of the windows across its lifetime. Following the initial cost of manufacturing and installation, you should also consider these lifecycle costs:

  • Maintenance requirements
  • Finishing treatments
  • Replacement intervals
  • Energy efficiency benefits

Although hardwood and modified timber may require a high initial financial outlay, the costs will be countered over their lifespan.

Installation Considerations

The complexity of a timber window installation project will have a big impact on the cost. Specialist fitting requirements to consider include:

  • Access requirements
  • Project timeline impact
  • Site-specific challenges
  • Conservation area status

Making an Informed Choice

Whether you’re an installer, architect, specifier or homeowner, you’ll want to know as much as possible about what material is the best and most cost-effective choice for you. Several factors will influence your final material selection.

Project-Specific Requirements

  • Conservation area restrictions
  • Building regulations
  • Client preferences
  • Environmental considerations

Performance Requirements

  • Thermal efficiency needs
  • Acoustic performance
  • Weather resistance
