From the Director
Why We Built TCM the Way We Did
"I'm the director of TCM Building & Maintenance Ltd, a trusted, all-in-one building company based in Borehamwood, serving Hertfordshire, North London, and surrounding areas."
We specialise in both domestic and commercial construction, offering a full range of services from initial design to final handover. Whether it's a home renovation or a commercial fit-out, we manage every detail with quality, reliability, and transparency.
What sets us apart is our dedicated team: structural engineers, architects, interior designers, and skilled tradespeople, all working together to deliver projects on time and on budget. You don't deal with a different company for each trade. You deal with us — one contract, one point of contact, one standard of work.
Ten years in, that model still works. Our Checkatrade reviews are published unedited. Our clients come back for their next project. That's the measure we care about.
What TCM Is, Precisely
A Full-Service Building Contractor — Not a Broker
The building industry has a fragmentation problem. Most contractors manage one trade and subcontract everything else, which means the homeowner ends up coordinating between a bricklayer, a roofer, a plumber, an electrician, and a decorator — none of whom are accountable to each other. When something goes wrong, the blame gets passed around.
TCM was built to solve that. We are a directly employed, multi-trade contractor. Our structural engineers, architects, project managers, and tradespeople are part of the same organisation. They work to the same programme, the same quality standard, and the same client.
That structure matters for your project. It means design decisions are made with the build in mind. It means the programme is realistic because the people writing it are the people doing the work. And it means when you call us, you speak to someone who knows your project — not a call centre.

The Team
Every Discipline Under One Roof
Most building companies manage one trade and subcontract the rest. We don't. Our team covers every discipline a building project requires, which is why we can offer a single contract from design to handover.
Structural Engineers
Load calculations, RSJ beam specifications, and structural drawings prepared in-house — no waiting for external consultants.
Architects
Planning applications, permitted development assessments, and full architectural drawings handled by our own team.
Interior Designers
Space planning, material selection, and finish specifications so the inside of your project matches the quality of the structure.
Skilled Tradespeople
Bricklayers, carpenters, electricians, plumbers, plasterers, and decorators — all vetted, insured, and regularly working together.
Project Managers
Every project has a dedicated manager who coordinates trades, manages the programme, and reports to you weekly.
CDM Coordinators
We fulfil the Principal Contractor role under CDM 2015 on all notifiable projects, managing health and safety documentation from start to finish.
