Timber sash window specialists for Dorset

Our Dorset work centres on made‑to‑measure timber windows, built to order and delivered ready for a competent joiner or building contractor to fit. We do not run a local fitting team in Dorset, and we will not imply otherwise. What we do exceptionally well is manufacture: taking the specific profiles, glazing bar layouts, box detailing and timber sections of your property and reproducing them faithfully in new joinery.

The core of what we make is the traditional box sash window, produced in either slimline softwood or durable hardwood depending on your building, its exposure and any conservation requirements. Where the local authority permits, we incorporate slimline double glazing that holds the slender sightlines a period window needs while improving comfort and reducing draughts. Where double glazing is not appropriate, for example on a tightly controlled listed building, we build single‑glazed sashes to the correct specification and can advise on secondary glazing as the sympathetic efficiency route.

Alongside sash windows we supply period‑correct casement windows, timber doors and fanlights, all made to match existing joinery. Every window is manufactured to order. There is no standard catalogue size doing the heavy lifting here; the dimensions, mouldings and meeting rails come from your building, which is what allows a new window to sit convincingly alongside original fabric. For owners of listed and conservation‑area homes in Dorset, that fidelity is usually the whole point of commissioning bespoke joinery rather than buying stock units.

We can supply components as well as complete windows. Where an existing box frame is sound but the sashes are beyond economical repair, we can build replacement sashes to drop into the existing boxes, which is often the least disruptive route and the one conservation officers prefer. Cord, pulley and parting‑bead detailing can be specified to suit, and we will discuss the ironmongery and finish options that best fit the age and status of your property.

We deliver made‑to‑measure timber windows across Dorset, including Blandford Forum, Sherborne, Dorchester, Bridport, Lyme Regis, Beaminster, Wimborne Minster, Wareham, Swanage, Shaftesbury, Corfe Castle, Abbotsbury and Milton Abbas, along with the surrounding villages and hamlets. Whether your property sits in a market town conservation area or in open countryside, the supply process is the same: accurate information in, precise joinery out, delivered to your door.

Dorset's building stock is unusually varied. Sherborne and Shaftesbury carry a strong Georgian and Victorian character with fine sash windows; Dorchester mixes Georgian townhouses with later development; the coastal settlements of Lyme Regis, Swanage and Bridport have their own weathered vernacular, where timber joinery must cope with salt‑laden air and driving rain. We take exposure into account when recommending timber species, section sizes and finishes, so a window destined for an exposed coastal elevation is specified differently from one on a sheltered inland street.

Many Dorset properties fall within conservation areas or are individually listed, and a good number sit inside the Dorset National Landscape. That planning context shapes what can be installed, which is why we build to match rather than to a generic pattern. Even though we are supplying rather than fitting, we design the joinery with those constraints in mind, so the windows that arrive are ones a conservation officer is likely to accept.

Our studio is based in London, in north London, and heritage timber windows are what we do. That specialism is the reason clients well beyond our on‑site service area come to us for supply. When you commission windows from us for a Dorset property, you are buying joinery made by people who work with period sashes every day and who understand what makes a replacement window sit right in an old building.

We build in both softwood and hardwood, select timber with the longevity of an exposed elevation in mind, and hold to the slender sightlines and correct mouldings that distinguish a proper sash window from a modern approximation. Where slimline double glazing is permitted we use it to improve comfort without coarsening the appearance, and where it is not we build to single‑glazed conservation standard. The result is joinery that respects the character of Dorset's historic homes while performing to a modern standard of comfort and weather resistance.

Choosing us for supply means accepting a clear split of responsibilities. We are accountable for the design and manufacture of your windows; your local Dorset installer is accountable for fitting them. For many owners and contractors that is exactly the arrangement they want, pairing a specialist maker with a trusted local fitter. If your property is within London or the South East and you would prefer our full on‑site service, including survey, restoration and installation, we would be glad to discuss that instead. For Dorset, made‑to‑measure supply, delivered to you, is how we can genuinely help.
