We design and install bespoke PVC-U windows tailored to period and modern properties. Our windows feature multi-point locking systems, thermal efficiency, and maintenance-free frames. Available in traditional sash or contemporary tilt-and-turn styles, each unit is manufactured to BS EN 1279 standards. Customers benefit from free quotes, on-site production, and a 10-year guarantee covering parts and labour.
Conservatories
Our custom-built conservatories combine aesthetic appeal with structural integrity. Using CAD technology, we create energy-efficient extensions compliant with building regulations. Services include groundwork, plumbing, and electrical work, all completed by in-house craftsmen. Each conservatory includes a 10-year structural guarantee and free planning assistance, transforming homes into light-filled spaces year-round.

Report
After being recommended by a friend I tried mr window. From day 1 with the estimater to fitting I knew we'd made the right choice. The company kept us informed throughout the process and our windows were fitted at the time agreed.our fitters Tony and burt made what could have been a stressful day a laugh a minute experience whilst being total professionals. From start to finish they were impeccably clean and fun to get on with. Definitely recommend mr window over any company we had quotes with for price and service.
