Sensitive Period-Home Replacements Across Dorchester (DT1)
Bespoke period property window work in Dorchester — surveyed on site, quoted in writing, backed by a 10-year workmanship guarantee.
Owners of period properties across Dorchester usually come to us for one of two reasons: draughty, rattling boxes losing heat, or badly-specified 1990s replacements that have aged the elevation. Both are fixable. We survey, itemise and quote in writing before recommending a route, working from Cranbrook via the A35 into Weymouth (7 mi south), Wool (10 mi east), Portland (12 mi south), Bridport (14 mi west).
Dorchester's older housing stock — georgian high west street townhouses and poundbury new-build classical in particular — needs frames that read right from the pavement. We match muntin widths, putty lines and reveal depth to what the street already holds, and work inside Dorset Council's expectations from the first visit.
Local context: Dorchester's housing splits sharply between the Georgian core and the Duchy of Cornwall's Poundbury extension, where design controls are extremely strict and only certain window styles and colours are acceptable. Common triggers we hear from Dorchester owners are non-compliant uPVC fitted to early Poundbury phases needing reversal and Georgian townhouse sashes rotted at the cill.
Housing stock around Dorchester skews toward georgian high west street townhouses, poundbury new-build classical, interwar victoria park semis — each has its own reveal depth, sightline expectation and detail that our period property spec answers directly.
A typical period property brief in Dorchester looks like Duchy-compliant flush sashes for a Poundbury townhouse, or on the refresh side, respraying inappropriate white plastic on a Poundbury phase-one property to an approved heritage colour.

Yes — we've worked on Poundbury phase one and two properties and can spec to Duchy guidance.
