"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...
How much does a bespoke conservatory cost?
A bespoke conservatory is a remarkably cost-effective way to create a one-of-a-kind home extension. Because these structures often fall outside the rigid requirements of traditional brick extensions – frequently bypassing the need for full planning permission – the build costs are often significantly lower. At Spire Windows, we manufacture our own uPVC systems in-house, giving us the flexibility to design a custom space that fits your specific budget. While the complexity, size, and choice of materials will influence the final price, our design team is dedicated to creating a unique, high-end space that remains affordable.
Will a bespoke conservatory add value to my home?
Absolutely. A bespoke conservatory is more than just an “add-on” – it is a designer feature that enhances both the aesthetic and the footprint of your property. Spire Windows specialises in unique builds where usability and appearance are paramount. By tailoring the design to your home’s specific architecture and garden layout, we create a seamless transition between indoors and out. This high level of “kerb appeal” and the creation of a truly usable, all-year-round room is a major asset that can significantly increase your home’s market value.
Do I need planning permission for a bespoke conservatory?
In many cases, even complex bespoke designs are considered “Permitted Development,” meaning you can extend your home without the delays of formal planning applications. This makes a custom conservatory a convenient, streamlined alternative to a traditional extension. However, because bespoke projects can sometimes involve larger footprints or unique roof heights, we always recommend a professional assessment. If your dream design does require planning permission, the Spire Windows team can manage the entire application and paperwork process for you.
What makes a bespoke conservatory the "best" choice?
The “best” conservatory is the one designed specifically for your lifestyle and your home’s character. A bespoke build allows you to break away from standard templates – think unique P-shaped layouts, T-shaped garden rooms, or custom colour matches. Because we manufacture our own frames, we can turn your specific vision into a reality. To ensure your new space is a “room for all seasons,” we offer solid, hybrid, or high-performance glass roofs, allowing you to enjoy a custom-built sanctuary no matter the weather.
