The Problem

Most homeowners are going in blind.

The construction industry is full of vague quotes, hidden costs, and work that doesn't match what was agreed. You shouldn't need to become an expert — you just need someone in your corner.

01

Quotes that leave things out

Many builder quotes are deliberately vague — missing groundwork, structural elements, or building regs costs that only appear once work has started.

02

Budgets that spiral

Renovation projects routinely go 20–40% over budget. Most of those overruns were predictable with the right planning and the right questions asked upfront.

03

No one honest to ask

Architects and surveyors are expensive. Friends and family mean well but don't know the trade. You need experienced advice without the jargon or the invoice.

Most Common Findings
•
"Important items missing from your quote."
Groundwork contingency, structural engineer fees, building regs sign-off. Catching these before you sign can save thousands.
•
"Inconsistent price variables from different builders."
Quotes that vary, from the hundreds into the tens of thousands. No more guessing — I can review the quotes and provide up to date costs/pricing in your local area.
•
"Payment schedules."
Upfront payments, inconsistencies in scope of work, requests for early payments due to arising issues. I'll review your payment schedule and suggest fairer stage payments, so you only pay for work that's been done.

About

Someone who's actually been on the tools.

I've spent over 25 years working in construction — on domestic extensions, commercial renovations, roofing projects, and everything in between. I've managed projects, priced jobs, hired subcontractors, and dealt with the full range of problems that come up on real building sites. I've also run two successful construction businesses of my own, giving me a deep understanding of the industry from both sides — on site and running the company.

I started Before You Build because I kept seeing the same thing: homeowners being overcharged, undersold, or badly advised — and having no one honest to turn to. Now I'm that person.

I work remotely, which means I'm accessible to homeowners anywhere in the UK — and I give the same advice I'd give a family member: straight, honest, and in plain English.
