Composite Doors Liverpool

Deter Intruders With a Stylish, But Formidable Composite Door

Find the perfect style of composite door to suit your home’s decor. We have styles to suit all types of homes, whether you’re in a terraced suburban street or fitting out your country home in the sticks. 

Our expert door fitters have been improving homes across Liverpool and the North West since 1995 and have built up a reputation for consistently delivering five-star service. We don’t believe in compromising on quality.

Our front and back composite doors are complete with the strength, easy maintenance, weather resistance and security that you’d expect from a top-of-the-range product. If you’ve been looking for front door inspiration and a smarter way to increase the security of your home, then trust Allerton Windows with your home renovation.






Incomparable Durability

Each door is constructed using a vacuum-formed high-impact skin. This durable, low-maintenance grained skin gives the door the classic look of a timber entrance door. Get the aesthetic value of a wooden door with the long life span that only a composite door can provide.

All our composite doors combine rigid uPVC with a reinforced aluminium inner frame. Each uPVC profile is strengthened by its own aluminium box section which is welded together for maximum rigidity. Combining these two materials in such a way creates the strongest composite door on the UK market.

Each composite Rockdoor we provide is thoroughly injected with Polyurethane Foam. The foam is piped into any gaps in the door within the uPVC and aluminium frame construction. Feel safe in the knowledge that the front door of your home is insulated to the best possible Door Set Energy Ratings.

All these doors come complete with nickel-coated solid brass hook locks. These Diamond Secure 3 Star Cylinders locking mechanisms run the full length of the door’s outer frame.


I've just had a new front door installed and it looks absolutely superb and has exceeded my expectations. Very professional from start to finish and the guys installing were brilliant too. Couldn't be happier. Definitely recommend. Thanks.

After reading the fantastic reviews for Allerton Windows we decided to contact them for a quote for a new window and front door. Within a couple of days one of the team came out (at the agreed appointment time, which we feel is very important), measured up and gave us a quote that we were happy with.

I’ve just had two bay windows, a front door and a stable door for the kitchen fitted and am extremely delighted with how they look, the fitters arrived on time and were extremely friendly, talked me through what was happening and always cleaned up at the end of the day. I would thoroughly recommend Allerton Windows to all me friends and family. THANK YOU !!!!!!!!!!!

Absolutely thrilled with my new windows and door, excellent product at a competitive price and extremely professional fitters, was told it would take 2-3 days and they were completed in a day, the fitters did not stop! Couldn’t ask for more, so glad I chose Allerton Windows and would highly recommend to everyone.

I spent a while looking for prices and Allerton windows were the most competitive I could find. The person I dealt with was really helpful with advice on what was available and the fitters themselves were gents. Whole house done in under 2 days with a minimum of fuss or mess.

  • How much are your Composite Doors?
  • All of our designs and installations are completely unique and based on your preferences. This means prices can change when it comes to colour, style and other modifications such as handles.

    As a guideline, our Composite Doors start from £1,800. These are averages and don't include any bespoke changes. To find out more, speak to us today!

  • What is the difference between a composite door and a uPVC door?
  • The key difference between a composite door and a uPVC door lies in their materials and construction. Whereas uPVC doors are made entirely of plastic, composite doors are composed of a number of different materials with the intention of making them stronger and hard-wearing.
    For example, the Rockdoor composite doors that we fit are composed of GRP (glass reinforced plastic) in addition to rigid uPVC profiles and reinforced aluminium frame boxes. This combines to create a door that is incredibly secure and thermally efficient.

  • Do composite doors fade?
  • Composite doors do not fade over time. This is one of their clear advantages over the more traditional door materials such as wood or uPVC. Rockdoor’s construction process includes vacuum forming a high impact skin onto an intricate aluminium mould. This low maintenance grained skin makes the colour much hardier than any other door finish.

  • Are composite doors resistant to scratches?
  • Our composite doors are made with a scratch resistant GRP material that is highly durable. As such you’ll find that all the composite doors that we fit will stand the test of time and remain an appealing feature of your home for a long time to come.

  • How long do composite doors last?
  • Composite doors have a typical lifespan of at least 30 years. Depending on the weather conditions and how well you look after it, yours could well last longer on this.

  • What materials are composite doors made of?
  • The Rockdoor composite doors we fit are made with the following:
    First a high impact skin is formed onto an aluminium mould.
    The inner frame is made using rigid uPVC profiles with an aluminium reinforced box section.
    S-Glaze glass is used to fit any windows that you require, providing excellent security.
    The door is then injected with Polyurethane Foam to ensure that any gaps are filled.
    The door is cut down to size using CNC technology before multipoint hook looks are fitted for maximum security.

  • How much do composite doors cost?
  • The cost of your composite door depends entirely on your project. Since there are numerous colours, styles, features and sizes to choose from we can only suggest an average of £1,400 per door. You must also account for professional installation.

  • Do composite doors require maintenance?
  • One of the best features of a composite door is that they don’t require much maintenance when compared to their wooden counterparts. One of the ways that you can extend the life of your door is by giving it a gentle clean once a month. This can be as simple as wiping it down with warm, soapy water and a soft cloth.

  • How strong are composite doors?
  • The Rockdoor composite doors that we fit provide industry-leading security that comes with a variety of features intended to make your front door impenetrable to intruders. S-Glaze technology, reinforced inner frames and nickel coated solid brass hook locks make these doors impossible to be forced open without industrial-strength tools.

  • Can you fit a composite door yourself?
  • We do not recommend that you attempt to fit a composite door yourself. Whilst it’s possible to do so, it wouldn’t be prudent to spend hundreds of pounds on a door to then risk compromising the security of that door by installing it yourself.
    Only by getting a professional to measure up and fit your composite door can you guarantee that it provides the outstanding security that you’ve paid for.
