"James and his team recently completed some building work for me. Not only did they go above and beyond to get the job done perfectly they also finished ahead of time. The team were fantastic with my two children running around (which can't have made things easy) and were on hand for any questions or queries I had. I wouldn't hesitate to recommend them to anyone looking for a fantastic end product and impeccable service throughout!"
Lucy Kemp 

"I can't recommend Mackbuild highly enough, they were friendly, accommodating and professional. Everyone comments on my extension and I love my new space"
Scott Sullivan - Thundersley

"I have used James Mackie over a number of years for large projects such as loft conversions and smaller carpentry work such as bespoke wardrobes and door hanging.  James is both personable and professional.  He listens carefully to what you are trying to achieve and takes pride in everything he does.  His customer service is superb.   He always gets back to you promptly following quotation visits and during any work is keen to feedback at the end of each day.  I highly recommend him."
Kate and Emma Day
