Aluminium windowsand doors, made tothe millimetre.
Measured on site by us, built to measure by professional aluminium suppliers and installed by our own team.
Most window and door problems come from fit and fitting.
Not from the aluminium. So we take care of both: we measure every opening ourselves, order from professional suppliers and install with our own team.
Doors that stick, rattle or let the wind in
Every frame is made to the exact size of your opening, then fitted and adjusted until it slides, closes and locks smoothly.
A quote that doesn’t say what you’re paying for
You get a written quotation that lists the products, finishes and glass we recommend, item by item.
Installers who disappear after the job
Our own team installs everything and stays available for after-sales service. You deal with the same people throughout.
One team, from the first measurement to the last screw.

Good questions to ask before you choose anyone.
Straight answers to the things people worry about most.
Ask us on WhatsAppIsn’t made to measure more expensive?
It can cost more up front than standard sizes, but a frame that fits first time avoids the cost of filling gaps, re-plastering and call-backs later. Your quote shows every item, so you can see exactly where the money goes.
I don’t know what I need yet.
That’s normal. Send us photos of the openings on WhatsApp. We will suggest the right products and, if it helps, come out to measure and talk you through the options.
Will it suit an older or unusual building?
Yes. Because everything is made for your openings, odd sizes, older houses and renovations are exactly what we are set up for.
What if something goes wrong later?
You call the same people who installed it. Our own team does the after-sales service, so nobody passes the problem on.
Four steps. One team. No surprises.
You always know what happens next, and who to call.
