Top job by Matt and the team for fitting the shutters, am very happy. Always a pleasure to have Matt working on our property, friendly, professional and tidy. If he ever wants a career change and wants to work with bicycles then send my way.Tony - Walthamstow Cycles E17

Thank you for today,

The most straight forward tradesman we have dealt with yet!

Mrs N.Ferstendik

I cannot sing Matt's praises enough.  There was not a speck of dust when he left as he cleaned up as he went and he was also kind enough to put my net curtains and heavy curtains back up for me.  It's a shame all workmen are not more like him.

Mrs K.Doughty, E17
