FAQ

Our Products

Questions we often get asked

We specialise in double glazed timber sash windows, casement windows, French doors, bifold doors, and front doors — all handcrafted to your exact specifications.

Absolutely. We create bespoke timber windows and doors designed to replicate your existing profiles, which is especially important for period and heritage properties where maintaining a consistent look is essential.

We primarily work with Accoya timber, which we recommend for its exceptional durability, stability, and overall quality. All of our timber is FSC-certified, meaning it is responsibly sourced.

We can also provide softwood as an alternative option depending on the project requirements.

We offer a range of glazing options including standard double glazing, acoustic glass for noise reduction, and specialist heritage glass for listed properties. Visit our Glass page for full details.

Yes. We offer an extensive range of paint finishes so you can match your existing colour scheme or go for something completely new. Take a look at our Paint Finishes page for inspiration.

Installation

Questions we often get asked

Timescales vary depending on the size and complexity of the project, but we aim to work as efficiently and neatly as possible.
 
As a guide:
  • A full sash window replacement typically takes around one day per window, per installer, including finishing and decoration.
  • A sash refurbishment (new sashes into existing frames) usually takes around 1 to 1.5 days per window, per installer.
  • Casement windows and frames are generally installed within a day by our team, depending on the number of windows and site conditions

We take great care to minimise disruption. Our team works tidily, protects your furnishings and flooring, and leaves everything clean when we’re done.

Yes. We handle the full removal and responsible disposal of your old windows and doors as part of our installation service.

All our installations are carried out by our own skilled team, so you get the same high standard of craftsmanship from start to finish.

Planning & Conservation

Questions we often get asked

Most replacement windows fall under permitted development and don’t need formal planning consent. However, listed buildings and properties in conservation areas may require approval. We can advise you on this when we visit.

Yes. We regularly work on listed and period properties. Our timber windows can be crafted to meet conservation officer requirements while still providing the benefits of modern double glazing.

We can guide you through the process and provide the technical specifications and drawings that local authorities typically ask for.

Energy Efficiency & Performance

Questions we often get asked

Yes. Double glazing significantly reduces heat loss compared to single-glazed windows, meaning your home stays warmer in winter and cooler in summer, which should be reflected in lower heating costs.

Timber is a naturally superior insulator. It retains heat more effectively than uPVC or aluminium, and when paired with high-performance double glazing, it delivers excellent thermal efficiency.

Definitely. Double glazed timber windows provide a noticeable reduction in external noise — particularly beneficial if you live near a busy road or in a town centre.

Aftercare & Maintenance

Questions we often get asked

Timber windows are low-maintenance with the right care. Periodic checks of the paintwork, keeping drainage channels clear, and repainting when needed will keep them looking great and performing well for decades.

Yes. All our windows and doors come with a guarantee covering both materials and workmanship. We’ll provide full details with your quote.

Yes. If your existing timber windows are structurally sound, we can refurbish, repaint, and upgrade them rather than replacing them entirely (a cost-effective and sustainable option).
