Our Story
About MM Contractors London
Over 20 years of trusted refurbishment expertise, right here in South West London.
Who We Are
A Wimbledon company built on craftsmanship and trust
MM Contractors London was founded by Mario Marotta and is based in Wimbledon, South West London. With over 20 years of hands-on experience in residential refurbishment, we have built a reputation for delivering high-quality renovation projects that our clients are genuinely proud of.
We specialise in full internal and external refurbishments of houses and flats — managing every element from structural alterations and plastering through to flooring, tiling, kitchens and bathrooms. Whether you are renovating a Victorian terrace, a period mansion flat or a modern apartment, we bring the same focus and care to every project.
We are particularly proud of our relationships with interior designers and design studios. We understand that a designer's reputation rests on the quality of their contractor's execution — and we take that responsibility seriously. Precise, clean, on programme.
If you would like to discuss how we can work together — whether for a single property or an ongoing collaboration — please do get in touch. Mario is always happy to meet for a coffee and a conversation.
