Expertly installed. Beautifully made. Built to last.
We’ve been supplying and installing high-quality windows and doors in Dorset for over 40 years. It’s what we do best — and we’ve built a solid reputation for combining expert craftsmanship with industry-leading products.
Whether you’re upgrading a single window or replacing every door in your home, we’ll help you choose the right materials, colours, and styles — all installed by our experienced, FENSA-registered team.
We offer:
- uPVC, Aluminium, and Hardwood options
- Windows and doors for all property types and budgets
- Supply only or full installation
- All jobs backed by Home Improvement Protection
We work with trusted names like Eurocell, VEKA, Rehau (uPVC), and SMART Systems (Aluminium). For hardwood projects, we’ve partnered with a brilliant local joinery business right here in Blandford — supporting other family-run firms just like ours.
Our workmanship will make your home stand out
We don’t cut corners — ever. Every window and door we install is built to perform in real homes, in real weather, for the long haul.
- Our aluminium systems come in over 750 colours with durable powder-coat finishes
- Our uPVC ranges include classic white, wood-effect (rosewood or cherry), and painted finishes
- Dual-colour options? No problem — green outside, white inside? We can do that.
- All finishes are weather-tested, backed by a 10-year adhesion guarantee, and resistant to cracking, peeling, or fading — even in harsh salt-air environments
And everything is fully compliant with British Standards and carries the appropriate Kite Marks for peace of mind.

Just love it, thanks so much David Fennings
Our aluminium framed conservatory has now been up for 20 years and continues to give us as much pleasure as the day it was finished. We live in it for 90% of the year enjoying its warmth and sunshine during winter plus glorious outdoor style in summer. Just love it. Thanks so much David Fennings. A proper job that brings the Med lifestyle to Dorset.

We highly recommend them
This summer, we also have had fantastic service from David Fennings Conservatories – we highly recommend them. They were most responsive to our particular needs and we cannot fault the standard of workmanship. The quality of our conservatory is great and even in the cold weather we are using it as an everyday addition to our house.

Highly professional, knowledgeable and genuine
David is a highly professional, knowledgeable and genuine gentleman that does not “hard-sell”. David and his team use only the best materials for the job at hand and are very experienced at what they do. Our current large conservatory has was installed originally by David and his team 24 years ago and still stands strong. I can highly recommend David Fennings Conservatories.

Correspondence was great
David did my aluminium double glazed by- folding doors at my house. The service from start to finish was superb. Correspondence was great. And the product is the best as my house backs on to the fleet at Weymouth where we get big south westerly winds carrying all the salt spray. They have been installed for 10 years now and operate and look new.

We can’t recommend them enough
