What They Say

I wanted to thank all the staff at Donalco for my wonderful window/door installation which was finalised this week.
I am thrilled to bits with the finished result and thought it appropriate to let you know.
Please pass on my sincere thanks to my installation team for the very professional way they went about their work.
Whenever I had a query they explained things to me clearly, and I enjoyed their company whilst they worked, they were so polite and courteous.
Thank You all for a job well done.
Kind regards, Anne Manly
