"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."

Why our Casement Windows?
Add character to your casement windows with our astragal bars or Georgian bars. Choose from a diverse range of colours, glazing, hardware and finishes to ensure the installation seamlessly blends into your home.
Lower Energy Bills
Because casement windows close flush against their frame, they create an exceptionally tight, compression seal. This superior design eliminates drafts, keeps the British weather out, and helps lower your home's energy bills year-round.
Safe and Secure
Casement windows are naturally one of the most secure styles available. Because the multi-point locking mechanisms are integrated directly into the window frame, they are incredibly difficult for intruders to pry open from the outside, keeping your family safe.

Here's some of our most frequently asked questions...
How much do uPVC casement windows cost for a typical 3-bedroom house?
The price of fully fitting a 3-bedroom house with new casement windows varies based on the number of openings, frame sizes, and your chosen finishes (such as frame colour and handle style). Because Spire Windows manufacture our own high-quality uPVC casement frames, we completely cut out the middleman. This allows us to offer highly competitive, transparent pricing with absolutely no hidden extras.
How long will new uPVC casement windows last?
A premium uPVC casement window should easily last upwards of 20 years, and often much longer. The lifespan heavily depends on the quality of the manufacturing and the durability of moving parts, like the outward-opening hinges. Spire Windows has been trading for nearly 40 years, so our bespoke frames have truly stood the test of time. With minimal maintenance, you can trust our installations to secure and insulate your home for decades.
How long does it take to install casement windows?
The installation time depends on the size of the aperture, ease of access, and how easily your old frames can be removed. However, our team of skilled craftsmen are experts at fitting casement styles with minimal disruption to your day. Spire Windows prides itself on a swift, efficient, and tidy installation process – we even responsibly dispose of all your old frames and glass, leaving your home spotless.
How do I know if my existing casement windows need replacing?
Tell-tale signs that it is time to replace your windows include noticeable draughts, condensation trapped between the glass panes, or casement hinges that have become stiff and difficult to open. Window technology has advanced significantly over the last decade. By upgrading to Spire Windows’ latest energy-efficient and highly secure casement frames, you’ll immediately improve your home’s thermal performance and kerb appeal, giving your property a fresh new lease of life.
