Premium Aluminium Doors
Aluminium is the premier choice for modern British entrances, offering a level of structural integrity that other materials simply cannot match. Unlike timber or uPVC, an aluminium door frame is exceptionally rigid and resistant to the elements, meaning it won’t warp, twist, or stick as the seasons change. This ensures that whether you are installing a residential front door or a high-traffic commercial entrance, the leaf remains perfectly aligned and effortless to operate year after year with virtually no maintenance.
The inherent strength of the metal allows for incredibly slim profiles that can support expansive, heavy glass units. This creates a seamless transition between interior and exterior spaces, flooding hallways or showrooms with natural light while maintaining a sleek, contemporary aesthetic.
Beyond its physical strength, our aluminium door systems are engineered for high-performance thermal insulation. Each door incorporates advanced thermal break technology and precision-engineered seals to act as a barrier against the cold. This prevents draughts and heat loss at your property’s most vulnerable points, keeping your interior climate stable and helping to drive down energy costs.

"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"

"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 do aluminium doors cost?
The price of a new aluminium door depends on the specific configuration – whether it is a sleek single entrance door, a set of French doors, or a large bifolding system. Factors such as the RAL colour finish and hardware choices also play a role. Because aluminium is a high-strength, premium material, it allows for larger glass panes and slimmer frames than uPVC. At Spire Windows, we manufacture our own high-quality aluminium systems, cutting out the middleman to offer these architectural-grade doors at highly competitive, transparent prices.
How long will new aluminium doors last?
Aluminium is incredibly resilient and can easily last 30 to 45 years. It is naturally resistant to corrosion, meaning it won’t rust, rot, or peel, even in harsh British weather. The lifespan is further secured by the polyamide thermal breaks and high-grade gearing we use in our frames. Spire Windows has been trading for nearly 40 years, so we have the expertise to ensure our bespoke aluminium doors are a “once-in-a-generation” investment for your home.
How long does it take to install aluminium doors?
Most single aluminium doors can be installed in half a day, while larger bifold or sliding sets may take a full day to ensure the tracks are perfectly levelled. Because aluminium is lightweight yet structurally rigid, it allows for a very precise installation. Our team of skilled craftsmen are experts at fitting these slimline systems with minimal disruption. Spire Windows prides itself on a swift and tidy process – we even responsibly recycle your old frames, leaving your home spotless and secure.
How do I know if my existing doors need replacing with aluminium?
If your current doors feel “heavy” to operate, suffer from significant heat loss, or have bulky frames that block your view, it is time to consider an upgrade. Many homeowners switch to aluminium to achieve a modern, minimalist aesthetic with slimmer sightlines that let in more natural light. By upgrading to Spire Windows’ latest thermally-efficient aluminium doors, you’ll immediately enhance your home’s security and kerb appeal, giving your property a high-end, contemporary finish.
