How we work
No vague promises — a clear process from first visit to final sign-off.
We come out, measure up and understand exactly what you want to achieve.
A clear, itemised quote with no hidden extras — you know the number before we start.
A signed agreement and a schedule so you know who's on site and when.
Foundations, frame and weathertight shell, inspected at every stage.
Trades sequenced properly — no waiting, no clashes, a tidy site daily.
A snag-free finish, sign-off and a written structural guarantee.

Who we are
Keystone Trades started with one van and a simple promise: turn up when we say, quote what we mean, and leave a site cleaner than we found it. Eighteen years on, that promise still runs the business.
We're a directly-employed team — not a phone number that subcontracts your job to whoever's cheapest. Bricklayers, joiners, plasterers and a project manager who answers the phone, all under one roof.
Client words
“Our extension came in on budget and a week early — spotless site the whole way through.”
“They project-managed everything. I made one phone call and it all just happened.”
“Proper craftsmen. The joinery is the sort you don't see any more.”
Send a few details and we'll book a survey — usually within the week.
