Infinity Doors and Windows fitted a composite door for us in 2010. All packaging was taken away and the area cleaned before they left. We are extremely pleased with our purchase and would have no hesitation in recommending them others.
Mr & Mrs Nimmo,

I was impressed with the workmanship of Infinity when they replaced a back window. I only needed one window replacing at the time. I liked the fact that I felt no pressure to buy anything else. I'll be calling them back to replace windows or doors as the need arises.
Mr Monaghan

I was delighted with the work Infinity did fitting my patio doors. Everything was left clean and tidy and I was delighted with the workmanship.
Mrs H. Williams,

Infinity Windows recently fitted our kitchen bow window. We were very impressed with their competative prices and high stanadard of finish. We will be using them again in the near future.
Mrs D Ealey,

All our windows and doors in our terraced property and have transformed the look of our home and to say we are pleased is in an understatement. Our home's also more secure and quieter. Also, the price we received from Infinity was the best we received.
