House Extensions
Single and double-storey, rear and side-return. Designed around how your family actually lives, built to full building regs.
What We Do
From footings to finish, one firm handles it all
No chains of subcontractors you've never met. Our own lads, our own scaffold, one point of contact from the first sketch to the final coat of paint.
Loft Conversions
Dormer, hip-to-gable and Velux conversions. Turn dead roof space into a bedroom, office or en-suite that adds real value.
Full Renovations
Back-to-brick refurbishments of period and post-war homes. Rewires, replumbs and replastering, done in the right order.
Kitchens & Bathrooms
Fitted properly, plumbed properly, tiled properly. We handle the lot: joinery, electrics, plumbing and tiling in-house.
Driveways & Landscaping
Block paving, resin, patios and garden walls. Proper sub-bases and drainage, so it still looks right in ten years.
Garage Conversions
The quickest way to gain a room. Insulated, damp-proofed and finished so you'd never know it was a garage.

What Clients Say
Trusted on the same streets for decades
“The extension was finished on the day they said it would be, for the price they quoted. The site was swept every single evening. You can't ask for more than that.”
Sarah Whitfield
Hale, Cheshire
“Third time we've used Ashworth & Sons over fifteen years. Peter's father built our first extension, and the standard hasn't slipped one bit.”
David & Margaret Ellison
Bowdon, Cheshire
“Our loft conversion was dusty work in a lived-in house, but the lads were polite, tidy and completely unflappable. The dormer looks like it was always there.”
