About
Replacement Sash Windows
At Country Hardwood, we specialise in expertly crafted timber sash window replacement, providing bespoke solutions that restore your home’s character while significantly improving its security and energy efficiency.
Our service is tailored for homeowners, architects, and property developers seeking the highest quality hardwood solutions. Manufactured in our Buckinghamshire workshop by experienced craftsmen, our windows are built for quality, luxury, and longevity.
Timber Windows for Listed Buildings
We understand that replacing windows in listed buildings requires the utmost care and adherence to heritage specifications. Country Hardwood specialises in crafting bespoke sash window replacements that replicate the original architectural features of period properties.
Our approach involves using heritage-spec timber like European Oak or Sapele, combined with traditional joinery methods to ensure authenticity. For conservation areas and listed buildings where modern double glazing may not be permitted, we offer traditional single glazing options.
Furthermore, we can perform sash-only upgrades, manufacturing new sashes to fit perfectly within the original timber box frame, thereby preserving the maximum amount of the building’s historic fabric while upgrading the window’s performance and functionality.
Glazing Options
Where required for listed buildings and conservation areas, we offer traditional single glazing to maintain historical authenticity. For urban environments, we have acoustic glass options for enhanced sound reduction, and for added peace of mind, security glass is also available.
Energy Rating
For outdated sash windows, a replacement—either of the full box or the sashes only—offers an immediate thermal upgrade by integrating modern weather seals and efficient glazing.
Frequently Asked Questions
Do you offer a full replacement service or just the sashes?
We offer both. We can provide a full box sash window replacement (frame and sashes) where the existing frame is rotten, or a sash-only upgrade where we fit new, highly-efficient sashes into your existing timber box frame if the window frames are in good condition.
What kind of wood do you use for the replacement sash windows?
We use premium-grade hardwoods chosen for their durability and natural beauty, including European Oak, Sapele, Accoya®, and Red Grandis. All our timber is sourced from sustainable, FSC certified suppliers.
Can wooden sash windows be double glazed?
Absolutely. We specialise in manufacturing traditional sash windows that are expertly retrofitted with high-performance double glazing (28mm units as standard) for enhanced thermal efficiency and acoustic efficiency.
Can you match the style of my existing windows?
Yes. Our new sash windows are bespoke and can be crafted to match your property’s existing architectural style, whether that’s a traditional 6-over-6 pane arrangement, Georgian bars, or Victorian-style sashes.
