About 4Moon Windows
A warmer, safer,
more beautiful home.
For more than 20 years we’ve helped families and businesses across Croydon and South London feel safer, warmer and prouder of where they live and work.
Who we are
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. A single uPVC window or a full set of aluminium bi-folding doors gets the same precision and care — and that approach has earned us repeat customers and word-of-mouth referrals across Croydon, Thornton Heath and South London.
“No pressure. Just the right solution for your home.”

Why 4Moon
Great products. Fitted properly.
We partner with Cortizo, Smart Systems and Rehau — systems engineered for British weather, tested for security and designed to keep their looks for decades.
A premium frame fitted badly is a wasted investment. Our installers are trained on the exact systems we sell, so every seal, hinge and threshold performs the way the manufacturer intended.
Proudly local
Just around the corner.
We supply and fit from 1A Lyndhurst Road, Thornton Heath, covering Croydon, Selhurst, South Norwood, Addiscombe, Purley and the surrounding neighbourhoods.
Being local means fast site visits, realistic timelines and a team you can actually reach after installation. You deal with us from first quote to final fit — product selection, guidance, installation and aftercare, all under one roof.

Questions
Good to know.
What areas does 4Moon Windows cover?
We supply and install windows, doors and roof lights across Croydon, Thornton Heath and the wider South London area, from our base at 1A Lyndhurst Road, Thornton Heath.
Do you supply and fit both uPVC and aluminium?
Yes — a full range of uPVC and aluminium windows and doors, including Cortizo, Smart Systems and Rehau products. We’ll help you choose based on your property, performance needs and budget.
How much do new windows and doors cost?
Prices depend on size, glazing, quantity, colour and hardware, so there’s no fixed figure. We provide free, no-obligation quotes tailored to your exact requirements.
Why choose a local company over a national one?
Faster response times, personal service and direct accountability. You deal with our team from first quote to final fit — and we’re close by if you ever need aftercare.
