In today’s world, security is no longer a silent afterthought in design; it’s a foundational requirement. That’s why Part Q of the Building Regulations exists: to ensure that every new home is built to resist intrusion, not only through good locks and solid materials, but through thoughtful design that makes security feel effortless.

At Mumford & Wood, we believe security should never interrupt beauty. It should live quietly within it, built into every frame, every hinge, every choice. Our timber windows and doors are not just built to meet Part Q. They’re crafted to make you feel secure from the moment you walk through them.

Designing Properties That Protect

Part Q applies to every new home in England and to buildings that have been converted into dwellings. It requires that all doors and windows accessible from the outside be designed to resist forced entry. But for us, compliance is just the beginning.

We go further, crafting windows and doors that protect what matters with:

  • Multi-point locking systems, engineered for reliability
  • Internally glazed units that prevent external tampering
  • Robust timber frames built for strength and longevity
  • Elegant finishes that never hint at the security beneath

Whether it’s a grand entrance door or a modest casement window, every product is built with intent, to endure, to perform, and to reassure.

The Beauty of Invisible Strength

True strength doesn’t need to shout. In fact, the most secure homes often don’t look “secured” at all. That’s what makes our joinery special: discretion. You won’t see the reinforcements or the security testing our products have passed, but you’ll feel their presence in the quiet confidence they bring.

You’ll notice it in:

  • The weight and balance of a door that closes with quiet authority
  • The ease with which a sash locks into place
  • The solid comfort of knowing your home is protected, without compromise

Our products are tested to the standards of PAS 24, which underpins Part Q. But the real test is how they feel in use: reliable, strong, and built for peace of mind.

More Than Compliance, A Sense of Assurance

When you build or renovate a property, you’re not just investing in square footage; you’re building trust. Part Q ensures that properties across the country meet a baseline of protection. But at Mumford & Wood, we help our clients go beyond that.

Because security is not only about:

  • Meeting regulations
  • Reducing risk
  • Satisfying insurers

It’s about building homes where people can truly relax, where the lines between function and form disappear, and where craftsmanship offers more than aesthetics; it offers safety, embedded into every detail.

A Partner in Safe, Beautiful Building

We work closely with architects, developers, and homeowners who care not just about what’s required, but about what’s right. Whether you’re designing a terrace of new homes or creating a single-family retreat, our team offers:

  • Expert guidance on compliant product selection
  • Design consultations to blend aesthetics with security
  • Timber joinery made to measure and built to last

Every home deserves that balance and the freedom to be expressive without being exposed.

Security, Redefined

We know that the word security can sometimes feel heavy. But to us, it’s just another layer of refinement. Another reason to trust what you build. Another way to protect the people who live inside.

So if you're looking to meet Part Q standards with elegance and ease, you’ve found the right partner.
