Mokas is a carpentry and construction company with over 24 years of experience in the building trade. Over the years, we’ve worked on all kinds of projects, from smaller carpentry jobs and home improvements through to complete renovations and major structural work. Renovations and alterations are a big part of what we do. We regularly work on existing properties, changing layouts, removing and opening up walls, installing steelwork, altering floors and ceilings, carrying out extensions and making structural changes right through to the roof. Carpentry and joinery are at the heart of our work. We have extensive experience in first fix, second fix, bespoke joinery and cabinet making. Kitchen fitting is also a big part of what we do, from assembling and installing kitchen units to fitting worktops, doors, panels and making sure everything is properly finished. Because we cover both carpentry and general building work, we can take care of different parts of a project without having to bring in several different trades. Whether it’s fitting a new kitchen, making changes to the layout of a property or carrying out a full renovation, we can take the project from the initial structural work through to the finishing touches. We believe in doing a job properly and taking pride in the finished result. We’re reliable, straightforward and easy to deal with. We keep the site as clean and tidy as possible, minimise disruption where we can and always aim to complete the work efficiently without cutting corners. After more than 24 years in the trade, we’ve built up the experience to deal with both straightforward jobs and the unexpected problems that can come up during renovations.

Carpentry- 3 Sep 2020
I would recommend Ben to anyone who wants a first class piece of joinery. Ben made 2 large double doors and replaced a section of decking. He moved his work around as the job was urgent, turned up when he said he would and worked late into the evening to get the job done. A first class service. Will most definitely use him again. Thank you, Ben.

Bathroom Fitting- 21 Apr 2025
Initially we were in touch with Dan about the installation of an extractor fan, but on his visit to the property it was clear that he'd be the right person to do much more. Essentially, he re-furbished the whole property, with a new kitchen, re-designed main bedroom, new front and back doors, a new flat roof over the bathroom, new shelving in the front room, painting throughout and clearing a derelict gazebo in the back garden. We were very happy with the advice and work that we received from Dan, including the way he brought in a couple of sub-contractors such as for carpentary and roofing.
