Sash Window Restoration Horsham

Where original sash windows remain, we believe in restoring them wherever possible. Our sash window restoration service brings tired, draughty, or damaged windows back to full working condition while retaining their original charm.

Restoration services include:

Timber repairs with Accoya or hardwood to match original profiles
Rebalancing sashes with new cords, pulleys, and counterweights
Draught-proofing to improve insulation and prevent rattling
Reglazing, including slim double-glazed units to boost energy efficiency
Sanding, priming, and repainting for long-lasting protection

We work with care and precision to ensure restored windows look and feel as good as new — while remaining historically accurate.

Sash Window Replacement Horsham

If your existing sash windows are beyond repair, missing entirely, or have been replaced with unsympathetic styles, we offer bespoke timber sash window replacements crafted to blend seamlessly with your home’s design.

Our handcrafted windows include:

Traditional box frames with cords and weights or optional spring balances
Accurate detailing, such as sash horns, glazing bars, and putty-line finishes
Heritage-friendly glazing, including slimline double glazing
Durable, breathable paint finishes for weather resistance
High-performance draught sealing and enhanced security features

Every window is made to order in our Sussex workshop using sustainably sourced FSC-certified timber.

Conservation and Heritage Experience

While much of Horsham has been developed in recent decades, there are several conservation areas and listed buildings — particularly around The Causeway, Denne Road, and parts of North Street.

We are well-versed in:

Meeting local conservation requirements
Matching original sash window designs
Supporting listed building consent applications

Our sash windows help preserve Horsham’s historic charm while offering the comfort and efficiency expected in a modern home.

Glazing Options

Living in a bustling town, near a main road, or under a flight path doesn’t mean you have to sacrifice peace and quiet—nor the classic style of your sash windows.

Noise Reductive

Privacy glazing is a common requirement in bathrooms, cloakrooms, and entryways—but standard modern options often look out of place in traditional homes.
