Why Choose Klosen?
Backed by 25 years in the trade, we are a committed team that provides the highest standards with every project. We ensure homeowners are satisfied with the result and the service we provide, and offer a fully bespoke design for an original, premium finish.
Experienced team local to Rutland
Partnering with Klosen means you’ll have access to an experienced, supportive team based locally in Market Deeping. This means we’re never far away and are perfectly placed to provide slimline aluminium windows in Rutland. You’re also welcome to visit our showroom to see the window designs before you make a final decision.
Swift, professional installation service
We offer a swift installation service, ensuring everything runs smoothly from our side. We’ll keep you informed at every step so you can spend more time working out the other elements of your renovation, new build or extension.
Fully bespoke
When we say fully bespoke, we mean it! All windows are made-to-measure and you get to choose the frame colour, finish, opening mechanism, handle design and whether you want double or triple glazing. If you’re overwhelmed by the options, we recommend visiting our local showroom, where our friendly team can talk you through your options.
Warranties for peace of mind
To reflect the confidence we have in our installation work and the craftsmanship and materials applied by the manufacturers, we offer 10-year warranties, along with a further 25-year warranty to cover the powder frame coatings. With aluminium and the coatings being naturally resistant to corrosion, we’re pretty confident you won’t need to use this warranty—it’s just there for peace of mind.
Aftercare support when you need it
Our support doesn’t end with the installation—we also provide exceptional aftercare and customer service.
