Your Trusted Windows and Doors Company in Croydon
Every home tells a story. Ours is simple: for more than 20 years, we've helped families and businesses across Croydon and South London feel safer, warmer, and prouder of the places they live and work. 4Moon Windows is a windows and doors company in Croydon built on craftsmanship, honest advice, and installations done right the first time. From our base in Thornton Heath, we supply and fit premium uPVC and aluminium windows, doors, and roof lights for homes and commercial properties across the region.
About Us
Who We Are ?
4Moon Windows was founded on a belief that home improvement should feel exciting, not stressful. Too many homeowners have dealt with pushy salespeople, vague quotes, and installers who vanish after payment. We set out to be the opposite. Led by Managing Director Hanif Mohammad, our team combines decades of hands-on fenestration experience with a genuine passion for design. We treat every project — whether it's a single uPVC window replacement or a full set of aluminium bi-folding doors — with the same precision and care. That approach has earned us something no advert can buy: repeat customers and word-of-mouth referrals across Croydon, Thornton Heath, and the wider South London area.
WHY 4MOON WINDOWS
Why Croydon Homeowners Choose 4Moon Windows
We partner with industry-leading manufacturers — Cortizo, Smart Systems, and Rehau — because great installation starts with great products. These systems are engineered for British weather, tested for security, and designed to keep their good looks for decades. A premium frame fitted badly is a wasted investment. That's why our experienced installers are trained on the exact systems we sell, so every seal, hinge, and threshold performs the way the manufacturer intended.
