Your homedeservescertainty.
Many homeowners tell us they have felt unsure who to trust. We built Prime Construct around one question: what would it take for you to feel confident from the first conversation?
One person.
Always Sam.
Sam is on site every single day. The person you meet is the person who leads your project. The same core team throughout, with clear ownership and no anonymous crews mid-build.
The quote
is the invoice.
Locked in writing before a single tool is unpacked. No revised estimates, and no price creep once work is underway.
You will never
be left wondering.
Consistent, proactive updates at every stage. You always know what's happening and what comes next. No chasing. No silence. No vague responses.
Accountable
after handover.
Every project backed by a 2-year warranty and £5m public liability insurance. Our commitment doesn't end when the tools are packed away.

Meet the Founder
Sam Flaxman built this company on one simple idea
“What if hiring a builder was actually a good experience?”
Sam set out to change the public's perception of small construction companies, with clear communication, agreed budgets from the start, and a habit of following through on what we promise.
Taking a personal and proactive approach, Sam is always on-hand and importantly, on-site, ensuring you're always fully up to speed. He employs his team directly, which means consistent quality, genuine accountability, and people who take pride in their craft.
The result? Renovations that are stress-free, on budget, and, according to our clients, genuinely enjoyable.
Common Questions
Questions we get asked
Straight answers on fixed quotes, timelines, warranties and how we work.
Our quotes are fixed-price. Once we agree the scope and the figure, that is the figure you pay — no hidden extras and no surprise invoices. If you later choose to change the scope, we discuss and agree any variation before work continues.
It depends on the scope. A kitchen renovation might take around 4 to 8 weeks; a full house renovation is often in the region of 3 to 6 months. We give a clear programme when we quote, Sam oversees each job, and we update you as work progresses.
In most cases, no. We plan the job to minimise disruption, keep the site tidy, and agree a week-by-week picture so you know what to expect. On larger whole-house renovations we will say if a short period away would be more comfortable.
Our site team is employed by us. That means one standard of workmanship, one programme, and the same people on your site from start to finish — not a changing roster of unfamiliar faces. Where we need specialist trades, we use proven long-term partners under our management.
We provide a 2-year Building Work Guarantee (BWG) on all general construction work, along with a 6-year BWG covering structural defects under our FMB Building Contract. Clients also have the option to take out an extended FMB Building Work Guarantee — insurance-backed cover for 6 or 10 years from completion. We carry public liability insurance of up to £5 million.
We work across all London boroughs. Many of our projects are in South and South-West London (for example Wimbledon, Fulham, Balham, Camberwell, East Dulwich and Bermondsey), and we are happy to discuss projects anywhere in Greater London.
