About Ultra Build Northwest
Owner-Led.
Manchester-Based.
FMB-Registered Builders Across The North West.
Ultra Build Northwest is a full-service building contractor run by Craig Grimsley, with a team of around 7 full-time staff and 20+ when our long-standing subcontractors (5+ years working with us) are on site. Covering Manchester, Cheshire and the wider North West. One in-house team. One foreman per project. Fixed written quotes that hold.
Our Story
Built By A
Working Builder.
Ultra Build Northwest is led by Craig Grimsley — on site every week, not behind a desk passing the work to a subcontractor he's never met. After 20+ years bricklaying, running crews and finishing homes across Greater Manchester, Craig set the business up around one principle: one team, one standard, from groundworks to handover.
We help homeowners and commercial clients across Manchester, Salford, Stockport, Oldham and Cheshire tackle the projects most builders either duck or bodge — full renovations, structural extensions, loft conversions, roofing replacements, silicone render systems and end-to-end new builds.
Our specialism is the full job. Foundations to final coat. One in-house crew, one point of contact, one set of standards. No sub-letting your kitchen to a stranger. No surprise charges three weeks in. Just the build you signed off, finished the way you were promised.
Mission & Standards
The Rules We
Refuse To Break.
Fixed Written Quotes, Always
Every job is priced in writing as a fixed price — costed by our quantity surveyor once drawings are in place. No verbal estimates that drift upward once we've started.
One Crew Per Project
Your project is led by one foreman from day one to handover. No rotating subcontractors, no faces you've never met.
Building Regs As Standard
Notifiable work is built to current UK Building Regulations and signed off through the relevant local building control authority.
Trade-Qualified In-House
Bricklayers, plasterers, joiners, roofers and groundworkers — directly employed or long-standing subcontractors we've worked with for 5+ years. No labour-only middlemen.
Clean Site, Daily
Site is swept, materials stacked and waste removed at the end of every working day. Your home is not our skip.
Honest Timelines
We quote realistic durations — not the shortest number to win the job. If weather or supplies delay us, you hear about it quickly.
By The Numbers
Proof, Not
Promises.
