Hallmark composite doors in a range of colours

Expect smart styling, dependable security and neat, long-lasting installation from a local, accountable team.

A great result starts with specification: insulated cores, high-performance glazing, compression seals that stay tight, and hardware set up to close positively with a light hand. We plan those details at survey so your new door feels right from the first evening you lock up.

Secure front door features — protection without bulky hardware

Security should be built in, not bolted on. Our specifications include:

  • Multi-point locking engaging robust keeps around the frame.
  • High-security cylinders with anti-snap, anti-pick and anti-drill protection.
  • Reinforced hinge points and hinge bolts to protect the hinge side.
  • Laminated safety glass in vision panels and sidelights where appropriate.
  • Police-approved PAS 24 configurations available for added reassurance.

From the kerb, you see clean lines and balanced sightlines — not heavy, obtrusive fittings.

Energy efficient external doors — warmth starts at the threshold

A smart entrance still needs to perform. Our energy efficient external doors combine:

  • Insulating cores or thermally broken frames to reduce heat transfer.
  • Low-E, argon-filled glazing with warm-edge spacers in panels and sidelights.
  • Compression seals and brush stacks that stay tight through seasonal movement.
  • Weatherproof thresholds and tidy cill details that shed water cleanly.

The payoff is steadier temperatures in your hallway and fewer cold spots near the door, even on blustery days.

Style choices — colours, furniture and glass

Make the entrance yours without creating maintenance headaches:

  • Colours: from crisp White and Cream to Anthracite, Slate and Black, plus heritage shades and dual-colour options.
  • Wood-effect foils: Golden Oak, Rosewood, Irish Oak and more for a convincing timber look on uPVC or composite.
  • Furniture: letterplates with draught control, knockers, numerals and handles in chrome, satin, brass or black.
  • Glazing: clear for maximum light, etched for privacy, or decorative options that echo period glass.
  • Side panels and top lights: widen the view and brighten the hall while maintaining security and insulation.

We’ll bring sample boards to your survey so you can compare finishes in natural light

Front doors vs back doors — different jobs, different specs

  • Front doors: first impressions count. We focus on colour accuracy, panel detail and glass that looks intentional from the street, with security and insulation under the skin.
  • Back doors: day-to-day practicality rules. Choose easy-wipe finishes, robust hinges and thresholds that handle constant use without scuffing or letting draughts in.

Both receive the same attention to sealing, fixing and alignment so they shut sweetly and stay that way.

uPVC front doors — value without compromise

Modern uPVC front doors deliver dependable insulation and low upkeep at an attractive price point:

  • Multi-chamber frames that limit heat loss
  • A broad colour and wood-grain palette with dual-colour options
  • Secure multi-point locks and high-security cylinders
  • Optional decorative or privacy glass that still meets energy targets

They’re a smart choice for rental properties, busy family homes or anywhere you want reliable performance with minimal maintenance.

Back doors that work as hard as your kitchen

Rear entrances see pets, shopping bags, muddy boots and recycling runs. We specify:

  • Easy-clean skins and frames that shrug off scuffs
  • Practical, weather-tight thresholds and brush stacks
  • Toughened or laminated glass where safety and security matter
  • Handle and lock sets calibrated for frequent use

If you prefer a full-glazed door for extra light, we’ll balance privacy with etched or obscure glass so the room still feels open.

Glass options that solve everyday problems

  • Privacy patterns for street-facing or overlooked doors
  • Solar control tints on sunny aspects
  • Acoustic laminates for homes on busier roads
  • Laminated security glass in low-level panes and sidelights

We specify room by room so you get the right mix of light, privacy and quiet.

Installation that makes the difference — fitted once, fitted right

Our method focuses on:

  • Measured survey for true openings, hinge side, swing direction, threshold height and any side-panel details
  • True, plumb, square frames fixed at correct centres to suit brick, block or stone
  • Correct packers and fixings that prevent distortion and maintain smooth locking action
  • Continuous internal air-seals and weatherproof external finishing to block micro-draughts
  • Threshold setting and drainage to shed water and avoid trip points

We protect floors, remove waste and hand over documentation and warranties at completion.

Compliance made simple — paperwork you can trust

Most like-for-like door upgrades don’t need planning permission, but they must meet Building Regulations for thermal performance and safety glazing. As a FENSA-registered installer we self-certify compliant work and provide your certificate for future property sales. If you’re altering the opening or live in a conservation-aware street, we’ll advise on sympathetic designs and any permissions.

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.

Questions

Your questions, answered

Are composite front doors more secure than uPVC?

Both can be very secure when specified correctly. Composite brings a denser core and very solid feel; uPVC offers great value with modern multi-point locking. Either can meet PAS 24 with the right hardware.

Can you match the new door to my windows and porch?

Yes. We coordinate colours, grains and furniture across doors, windows and roofline so the elevation looks intentional.

Will a dark colour fade?

Modern foils and skins are UV-stable. With simple, non-abrasive cleaning, deep tones like Anthracite or Black keep their colour for years.

I want more light but not a ‘fishbowl’ hall — options?

Use etched or patterned privacy glass in the door and sidelights, or add a top light to draw daylight deeper into the hallway without exposing the interior.

Are low thresholds weather-tight?

Yes — when detailed correctly. We balance accessibility with weathering and set drainage so water goes out, not in.
