He prices your job himself, works on it himself, and answers the phone himself, so the person who told you how it would go is the person building it. Request an estimate 07915 976616 The story ## Ten years in the trade, working across Cambridgeshire Jack Prime has spent ten years on the tools and runs every job the same way: get the foundations right, set the work out properly, and don't cover anything up you wouldn't want looked at later. That standard is carried into a business homeowners can actually get hold of. Prime Build Services Ltd covers Cambridgeshire, Huntingdon and the surrounding areas, along with the counties around them. Most customers are homeowners: people adding space to a house they intend to stay in, opening up a cramped ground floor, replacing a failed garden wall, or putting right brickwork that has been patched badly by someone else. We also take on new-build homes for private clients. The work spans the whole build, not one slice of it. Foundations and groundwork, structural openings and steel beams, brickwork and stone, roofing on extensions, and the outside work that finishes a property off, patios, block paving, walls, fencing and full garden redesigns. Where a job needs a specialist trade, Jack Prime brings in people he has worked with for years rather than whoever is cheapest that week, and he stays responsible for the job either way. What that means for you is one point of contact from the first look at the job to the last day on site. You won't be handed to a site manager you've never met, and you won't be chasing an office for an answer about your own house. ### Who we build for Homeowners across Cambridgeshire, plus private clients building a new home from scratch. ### What we specialise in Extensions, renovations and structural openings, backed by proper brickwork and groundwork. ### Experience 10 years in the trade for Jack Prime, on site daily. ### Where we work Huntingdon, St Neots, St Ives, Godmanchester, Cambourne, Cambridge, Sandy, Hemingford Grey and the surrounding county. How we work ## Standards we don't move on Most of the complaints homeowners have about builders come down to three things: work covered up before it was right, a price that moved without warning, and nobody picking up the phone. We run the business to remove all three. Ground and foundations are done to the depth the job needs, not the depth that's quickest. Structural openings are propped and supported properly and built to the engineer's details. Brickwork is set out before it's laid so courses, perp joints and the pattern line through. And the site gets cleared down at the end of each day, because you're living there while we work. Every completed job carries a 6-month workmanship guarantee. The company holds £2 million public and employers' liability insurance. If something isn't right within the guarantee period, you ring Jack Prime and he comes back. - One point of contact from first visit to final clean-down - Priced after a proper look at the job: no guessing from a photo - Changes discussed and agreed before they're carried out - Work built to approved drawings where a job needs them - 6-month workmanship guarantee on completed work - £2 million public and employers' liability insurance - Subsidence work is not undertaken, we'll say so and point you elsewhere - Phone answered 24 hours a day, 7 days a week The proof ## What we can actually stand behind 5.0 Google rating from 36 reviews 100% recommended on Facebook 10 yrs In the trade Jack Prime on site daily £2 million Insurance cover Public & employers' liability 6 months Workmanship guarantee On every completed job Read the full reviews or see examples of recent work.
