"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."

Here's some of our most frequently asked questions...
What is the cost of a standard uPVC window for a 3 bedroom house?
The cost of uPVC windows for a 3-bedroom house will vary depending on the size, style and frame colour. Frame efficiency and security rating, installation costs and the quality of the brand/ fitting are all important factors. Spire Windows manufacture they own quality uPVC frames so there’s no middle-man and they operate a competitive, transparent pricing policy so their prices are keen and there are no hidden extras.

Depending on the frame/ glazing quality uPVC windows can last for more than 20-years and some even longer. Spire Windows only install high quality uPVC windows and doors so with the correct care so you can rest assured Spire’s products will serve you well for many years to come. Having traded for nearly 40-years, Spire Window’s products have passed the test of time.
How long does it take to fit a new uPVC window?

Spire Windows only employ skilled craftsmen so your new windows and/ or doors will be fitted with care, attention and minimal disturbance. Spire aim to inconvenience you as little as possible, so they install their products as swiftly and efficiently as possible and they take all your old frames away.
How do I know when my uPVC windows need replacing?
