About us


A-SPEC was founded in 2008 by Jonathan Claffey, an experienced carpenter and joiner with a 14+ year track record gained working in the construction industry. His mission has always been to provide his customers with an exceptional experience, delivering the kind of meticulous attention to detail that many other building contractors struggle to achieve.

Jonathan has a real passion for working with wood. By using updated methods of construction, he is able to increase productivity both onsite and offsite, providing excellent customer service. He says: “What makes my job so satisfying is the pleasure of seeing the spaces we’ve created and, of course, the happiness we’ve achieved for our clients who now have a wonderful space to enjoy for many years to come.”

Over the last 10 years, A-SPEC has grown significantly. The professional team now consists of 20 skilled and experienced craftsmen and 4 office support staff, who are all dedicated to providing the best possible customer journey.

As an independent company specialising in joinery, carpentry and structural carpentry for private and commercial clients in London and Surrey, A-SPEC offers a complete design to completion service.

What our Clients Say…


We were very happy with the A-Spec team. The end result was marvellous - a beautiful custom built outside seating area we can enjoy for years to come. What really impressed us was the attention to detail and quality of work they showed, even staying on longer than planned to make sure it was perfect for us. They really went the extra mile and it shows. A-Spec is courteous, trustworthy and extremely professional. We will be using Aspec for all our work in the future. Can’t recommend them enough!

A-Spec has recently completed our loft conversion; it’s been such an excellent experience from start to finish considering how much we were dreading it! Jonathan and the team were outstanding and considerate throughout the project; everything was transparent regarding time scales and pricing with regular updates which we found really helpful. The best being the loft was finished on time and on budget. We’re very happy with the finished result; we’d highly recommend A-Spec.

Recommended by a friend and he couldn’t have been more right - work done to a very high quality and had some imaginative solutions for issues. Work done included cupboards, shelves, wall-mounting TVs and putting the wiring inside the walls and electrical work too
