About us
Nine Years of Joinery, Run by the Owner Who Quotes the Work
Impact Joinery is a joinery, carpentry and multi-trade business run by Mark Marchbank from Cumbernauld, serving homes and businesses across Glasgow and the Central Belt.
Our story
A small team, a straight process, a proper finish
Impact Joinery is owned and run by Mark Marchbank, supported by a small team of experienced joiners and carpenters depending on the project. We work for homeowners, landlords and businesses, and we specialise in joinery, carpentry, bespoke cabinetry, kitchen installation and the finishing work that decides whether a room looks completed or merely filled.
Nine years on the tools teaches you where jobs go wrong: prices given without seeing the property, floors that were never levelled, and contractors who disappear when a door drops six months later. We built the way we work around avoiding all three. You get a site visit, a fixed price wherever the scope can be established, and a 12-month workmanship guarantee once the job is finished.
The practical benefit for you is fewer moving parts. Mark quotes the job and stays accountable for it, and where plumbing, electrical or other specialist work is required we bring in qualified tradespeople and coordinate them, so you have one point of contact from the first phone call to the final tidy-up.
Our day-to-day working area runs from Cumbernauld through Glasgow and across the Central Belt, and we travel further into Scotland for larger projects. We take the same care on a single set of alcove shelves as on a full kitchen refit or a shop fit-out. Smaller jobs are how most customers meet us; the bigger ones tend to follow.

What that means for you
- A price you can plan around, given after we've seen the job
- One contractor accountable for the whole result
- Work sequenced around your household or trading hours
- Quality materials and proper preparation, not shortcuts hidden behind trim
- A guarantee in writing, with the terms confirmed in your quotation
Mission & standards
Measure properly, quote honestly, finish to a standard we'd accept at home
Six working rules that shape every job we take on, whether it is one door or a full kitchen.
Measure on site, never over the phone
Every quotation follows a site visit. Walls out of square, floors out of level and old timber behind the trim all change the job, and we would rather find them before the price than after it.
Preparation before finish
Floors levelled, substrates prepared, fixings taken back to something solid. The parts you never see are what keep doors closing and worktops sitting true years later.
Fixed prices where the scope is clear
Where the work can be pinned down, you get a fixed price in writing. Where it genuinely cannot, we say so and explain what would change it rather than burying an extra in the small print.
A guarantee in writing
A 12-month workmanship guarantee covers issues arising directly from our installation or workmanship, with the full terms confirmed in your quotation.
One accountable contractor
Where plumbing, electrical or other specialist work is needed, we bring in qualified tradespeople and coordinate them, so you are not project-managing five contractors.
Work sequenced around you
Domestic jobs planned around the household; commercial jobs planned around trading hours and handover dates.
