Dean Cowell was punctual for our estimation. He was very personable and efficient. Thanks for your time and good quote.

Well, after getting a quote for a new Conservatory we thought this was really expensive but wanted to meet with Michael Duffy to understand how we can make changes without affecting quality of end product but get the price down. We have sent multiple emails and made numerous phone calls and nobody is ever in contact with us. After waiting 6 weeks for an exorbitant quote I am afraid I cannot recommend this company as we can't ever get hold of someone to help us. Their reviews on Facebook also leaves one with little confidence in them.

I've used Fineline to fit the windows and doors in three of my previous homes. The first order being placed over 30 years ago. It's good to see their standards and quality have not only been maintained but have improved in all that time.

Tony did our windows and front door - he did an excellent job, left everything really clean and tidy. It looks great, would definitely recommend asking Tony to do your main work.

We enjoyed meeting Mr Howard Pryce this morning. He is clearly a very experienced salesman, and we were impressed with his expert knowledge of all aspects of the sector, from the technical to the wider commercial context, and his ability to explain it clearly, articulately and in a balanced way helped to convince us that in choosing FineLine we have made the right choice for our particular needs.
