Hayden and team delivered a great service from start to finish.well done

"Exceptional service "

We purchased a composite door from Costello Windows and apart from a mix up with our order the finished product was well worth waiting for. James Keane, the fitter, arrived early and worked for the whole day non stop until he had the door fitted. His work was exceptional and you can tell he takes great pride in his work. We are delighted with both the fitting and the product itself. I would definitely recommend this company for their superior products and skilful fitters.

"Highly recommend Costello Windows"

We would happily recommend Costello Windows. Brenda was so lovely to deal with when initially getting our quote and order placed. She was always so helpful as was Brendan. Jerry and Michael fitted the door and they did such a great job. So neat, perfectly plastered around the door and cleaned up after the job was done. They were absolutely excellent. The door is beautiful and we are delighted with it. Will definitely order from Costello Windows again. Many thanks.
