Hallmark composite doors in a range of colours

Composite front doors — first impressions that last

Your entrance sets the tone. We help you design a door that suits the architecture and the street:

  • Traditional: deep-panel designs, wood-effect foils, heritage glass and period furniture in brass, chrome or black.
  • Contemporary: sleek skins with long stainless bars, etched or clear glazing and bold colours like Anthracite or Black.
  • With sidelights: maximise hallway light using patterned, privacy or laminated glass.
  • With top lights: maintain headroom and symmetry where transoms define the façade.

Every composite front door is made to measure, with neat sightlines, tidy seals and a threshold that looks intentional from inside and out.

Security as standard — without bulky hardware

Great doors should be welcoming to people you know and unwelcome to those you don’t. We specify:

  • Multi-point locking engaging robust keeps along the frame.
  • High-security cylinders with anti-snap, anti-pick and anti-drill features.
  • Hinge bolts and reinforced screw-ports to protect the hinge side.
  • Laminated security glass in vision panels and sidelights where appropriate.

Ask about secure composite door configurations that are police-approved (PAS 24) without changing the external look.

Energy performance you feel in the hallway

A cold entrance drags down the whole ground floor. Composite doors help by combining:

  • A dense insulating core to slow heat transfer.
  • Low-E, argon-filled glazing in panels and sidelights for low U-values.
  • Compression seals and brush stacks around the slab and threshold to block draughts.
  • Warm-edge spacers in glazed cassettes to reduce perimeter condensation.

The result: steadier temperatures, fewer cold spots by the door and a calmer, quieter hall.

Colours, finishes and furniture — make it yours

Go classic or bold. Popular composite doors colours include White, Cream and Chartwell-style greens, through to Anthracite, Slate and Black for modern contrast. Wood-effect foils — Golden Oak, Rosewood, Irish Oak — bring warmth without the upkeep. Finish the look with:

  • Furniture: letterplates with draught control, knockers, numerals and handles in satin, chrome, brass or black.
  • Glazing: clear for light, etched for privacy, or decorative units to echo period glass.
  • Thresholds: low, accessible options that stay weather-tight and easy to clean.
  • Dual-colour choices: a statement colour outside, fresh White inside to suit décor.

We coordinate with your windows and roofline so everything reads as one design.

Back doors that work as hard as your kitchen

Rear entrances see the most traffic — pets, shopping, muddy boots. We specify finishes that wipe clean, robust hinges that shrug off daily use and glass that balances light with privacy. Add integrated blinds, laminate for security, and practical thresholds for step-free access without inviting draughts.

French, patio and bi-fold connections

Upgrading an entrance often triggers ideas elsewhere. We regularly combine composite front doors with:

  • French doors for classic garden access with secure locking and slim frames.
  • Patio doors (sliding) to frame views while saving floor space.
  • Aluminium bi-fold doors that open whole walls for entertaining.

We’ll keep colours, cills and hardware consistent across the set, so your elevation feels intentional.

Hallmark composite doors and other trusted systems

We work with established suppliers — including Hallmark composite doors ranges — selected for reliable skins, colour stability and robust hardware ecosystems. That means consistent quality, easy part support over time and designs that look sharp on day one and still do in five years.

Installation details that make a premium difference

A premium slab underperforms if it’s poorly fitted. Our installation standards focus on:

  • True, plumb frames so locks engage smoothly and the door doesn’t rub.
  • Correct packers and fixings matched to brick, block or stone.
  • Continuous internal seals and weather-tight external finishing to block micro-draughts.
  • Threshold setting and drainage that shed water and stay easy to live with.
  • Neat finishing with colour-matched sealants and aligned trims.

We protect floors, remove waste and walk you through operation before we leave.

Regulations, compliance and paperwork made simple

Most like-for-like door replacements don’t need planning permission, but they must meet Building Regulations for thermal performance and safety glazing. We handle compliance and provide documentation on completion. If you’re changing openings or live in a conservation-sensitive street, we’ll advise on sympathetic designs and any consents.

We had our windows and doors replaced by Sureseal Windows and could not be happier. We had a home visit from the salesman, who went through the various designs and colours available plus an initial measurement of all the items needed. Following our agreement to purchase the doors and windows a supervisor visited to precisely measure the openings and look for any issues that might arise during the install. The fitting was booked in about 10 weeks later. Alan contacted us to give his ETA of the morning of the start of the job. And we cannot praise Alan enough for his work and cleaning up after. All areas where work was done were covered with dust sheets and no mess was left. There were a couple of remedial jobs to be completed when the parts were available. Sean completed these jobs for us over a coarse of a morning. And, as with Alan previously Sean's work was great and all was cleaned up on completion. Both workers are a credit to SureSeal. And we highly recommend the Company.

From initial call from Sureseal making appointments to choosing our windows all the team have been very knowledgeable and helpful, No big sell to get the costs up just what we wanted and even reduced aspects no of closers etc. to meet requirements. Plenty of payment options with full explanation again no push either way. Survey was again very straightforward and with some discussion even more savings found. Pleasure to do business with. Great service and very knowledgeable.will post photos of finished project once complete. Mike Hedges

Questions

Your questions, answered

Are composite doors secure enough for the front?

Yes. With multi-point locking, high-security cylinders and laminated glass options, composite doors provide strong protection; PAS 24 specifications are available.

Will a dark colour fade in the sun?

Modern skins are UV-stable. With normal cleaning (no harsh abrasives), colours such as Anthracite or Black keep their depth for years.

Can I have more light without losing privacy?

Choose etched or patterned glass in the door and sidelights, or use decorative units that diffuse views while maintaining brightness.

Are thresholds accessible and weather-tight?

Yes. We specify low, compliant thresholds with good brush stacks and seals so they’re easy to cross and tough against weather.

Can you match my new door to existing windows?

Absolutely. We coordinate colours, grains and furniture so your composite front doors tie in with uPVC or aluminium windows and roofline.
