About MASCO

Hertfordshire Growth Hub
Hertfordshire Growth Hub is the county’s flagship business support provider. Powered by Hertfordshire Local Enterprise Partnership, we’re driven to help local businesses by offering instant access to advice, resources, events and other support providers, all in one convenient place.
Build. Protect. Secure.
Masco Doors is a specialist door supply, installation, maintenance and repair business supporting councils, housing providers, local authorities, commercial clients, managed properties and heritage sites.
Masco Doors has been developed from the wider Masco FM capability, bringing together practical facilities-management experience, public-sector understanding, security awareness, property-maintenance knowledge and a commitment to outstanding service.
We work with clients who need more than a door supplier.
They need a partner who understands property, people, resident safety, building function and long-term value.
We focus on:
- Understanding the client’s property portfolio
- Recommending the right door for the right location
- Supporting safety, security and resident confidence
- Delivering high-quality installation
- Maintaining doors after installation
- Helping clients manage door assets over time
- Providing clear, practical reporting
- Working sustainably wherever relevant
- Offering responsive, accountable service
Our Ethos
You cannot buy better quality or get a better service. That statement sits at the heart of Masco Doors. We believe clients deserve honest advice, reliable delivery, good communication, strong products and proper aftercare. We do what we say we will do.
Our Clients
Masco works with councils, housing providers, commercial clients and heritage sites. Our experience includes work with councils such as Dacorum and St Albans, as well as heritage environments including Ashridge House. References are available on request.
