Client Feedback

What our clients say.

Reviews coming soon Verified ratings to be added
A
[Client Name] Manchester

"[Your real review quote will go here — Andy to provide. Aim for 2–4 sentences mentioning the project type, communication and finish quality.]"

B
[Client Name] Didsbury

"[Second review quote — ideally on a different service such as a loft conversion, kitchen, or commercial fit-out so the social proof feels broad.]"

C
[Client Name] Chorlton

"[Third review quote — perhaps from a landlord on an HMO conversion, or a commercial client. Variety of client types = stronger social proof.]"

The questions we hear most often before clients hire us. If yours isn't here, just call.

Yes — for most projects we'll prepare drawings and submit the planning application on your behalf, or work with your architect if you already have one. We also handle Building Control sign-off through the build.
A single-storey rear extension typically takes 10–14 weeks on site once foundations are in. Double-storey and wrap-arounds run 14–20 weeks. Loft conversions usually take 8–12 weeks. We give you a programme up front and stick to it.
Most clients stay put. We seal off work areas, protect floors, and keep the site tidy at the end of each day. For kitchen-affecting jobs we'll plan around mealtimes and discuss temporary arrangements with you.
