"The entire team were totally professional from start to finish. Ultra friendly and comprehensive in their systems. Fitters loved a bacon bun too"
"From start to finish we had outstanding customer service. I can honestly say the best of the best windows and doors I’ve seen from spire windows. I’m not just saying this but the quality of each window is outstanding and the 2 men that fitted Ian and Bernard worked extremely hard to get our windows and doors fitted in 4 days they fitted 10 windows and 2doors front and back. Both men were friendly , honest and polite . If you are thinking of getting new windows ,doors etc I can recommend Spire Windows in Louth"
"Very professional from start to finish. From our first visit and quote to the installation of our windows and door. The timeline was pretty much as quoted and the two installation technicians, Paul and Correy, were very good, professional and respectful of our property. Thank you."
"Excellent service from start to finish. Really tidy workers no mess and very efficient all of them .would certainly recommend this company"
"Had 10 windows and 3 doors fitted by Spire. From the initial meeting with Peter to the installation everything was explained in detail professionally. No hard sell like other companies just a fair price for great quality windows. The installation team were friendly, hard working and tidied up after themselves despite some very challenging weather."
