"Costello Windows"

Costello Windows were professional, and easy to deal with from start to finish, and I'll be ordering from them again.
Breda,in sales, was friendly and accommodating when choosing the door. Gerry and Jack installed the door. Gerry was proficient, neat, and took great pride in his work. He didn't just install the door but adjusted the floor and plastered to walls around the door with perfection. We are delighted with our Costello Palladio door and would highly recommend

I have had my front door, front windows, bedroom window and now my patio doors replaced by Costello Windows. I can totally recommend this company for their skilled workmanship, great communication and competitive pricing!

Hi highly recommended Costellos

"Excellent custumer service from start…"

Excellent custumer service from start to finish. The Fitter arrived spot on time and worked through until finished. The door looks great. Very happy.

"The service from start to finish was…superb"

The service from start to finish was superb and we are delighted with the quality of door also. From the very start when I emailed many companies seeking a quote for a new front door, Breda in Costello Windows rang me that evening (on a Friday when you don’t generally expect to get a call back) with a quote. I was told the door would be installed within ‘approx’ 12 weeks, I think it was installed on the 13th week which we were delighted with. The fitters came when they said they would and the door was installed quickly and efficiently. There was a bit of untidiness around the door after installation but that is to be expected when doing a job like that. Overall, we are delighted with our experience with Costello Windows & Doors and would have no hesitation in recommending them.
