About This Service
Window Surveys & Conservation Assessments, Handled from Start to Finish
Our team of sash specialists carry out free, on‑site window surveys and conservation assessments across Manchester and neighbouring towns. Family‑run and practising traditional joinery for 40 years, they inspect timber, joints, sash operation and glazing, then produce a clear condition report. Recommendations cover repair, secondary glazing or discreet double glazing that respect conservation area and listed building requirements.

Our Process
How It Works
Free on‑site survey
A sash specialist visits your property to inspect frames, sills, pulleys, cords, glazing and draughting, recording defects and taking photographs.
Conservation assessment
We assess whether repair, secondary glazing or discreet double glazing best suits the building, noting any listed or conservation area constraints and practical trade-offs.
Clear report and next steps
You receive a written condition report with priority works, recommended specifications and a follow‑up quote for repairs or upgrades tailored to the property.
Benefits
Why Choose us for Window Surveys & Conservation Assessments?
Practitioner‑led, conservation‑minded advice
Surveys are carried out by sash specialists who understand timber, joinery and the practical options that preserve original fabric while improving performance.
Free, no‑pressure on‑site inspection

Half a century of local experience
Family‑run for 40 years, RW Sash Windows knows Manchester terraces, villas and civic properties and how to meet conservation area expectations.
What our survey covers: every free survey includes timber condition, sash operation, sill and head defects, glass type and draught paths. We photograph problem areas and note original detailing that should be retained. The aim is to recommend the least intrusive, longest lasting solution: repair where possible, sympathetic secondary glazing or discreet double glazing where appropriate.
Conservation and listed buildings: our assessments are written for owners and agents who need clear, practical guidance. We do not promise planning outcomes, but we provide a conservation‑friendly specification and evidence that can be submitted with applications. Practical advice on priority repairs, continuity of finish and matching mouldings ensures the work protects the building's character.
