Composite & uPVC Doors
An entrance door is often the first impression of your home, and with a wide range of panel designs, colours, glazing options, and hardware choices, you can fully customise your new door to create a welcoming entry for both you and your visitors.
In addition to enhancing kerb appeal, a new, thermally efficient door will eliminate drafts and in turn reduce your energy bills. With the growing concerns for home security, robust locking mechanisms and intruder-resistant features offer added peace of mind.
There is also a variety of threshold options to accommodate different installation needs, including low aluminium thresholds that ensure smooth wheeled access.
For composite doors, we supply and install Rockdoor Composite Doors, the original and market-leading manufacturer with the longest history in the industry. Rockdoor uses innovative manufacturing processes, setting their doors apart from the other options available on the market. The Rockdoor Composite Door range includes not only traditional entrance doors but also French Doors and Stable Doors, offering a variety of options to suit your needs.
What makes a Rockdoor unique?
1.Aluminium Reinforcing: Rockdoor features a rigid 360° welded framework. This is further reinforced with a continuous 10mm aluminium box section. The door is then injected with high-density PU foam, ensuring all gaps are filled creating exceptional security and superior insulating performance.
2. Integrated Glazing: Rockdoor’s S-Glaze technology seals the glazing units within the door’s inner and outer skins, meaning that intruders can not remove the glass—a common method used to gain access. This design also prevents drafts, as there are no exposed glazing seals that can deteriorate over time.
3. Steel Mesh (Optional Upgrade): A Rockdoor is already 35% stronger than a standard GRP composite door. For enhanced strength and security, steel mesh reinforcement can be added inside the door leaf, making it impossible to cut through without the use of diamond tipped circular saw—not something a burglar could discreetly use.

While Rockdoor offers exceptional quality and durability, low-cost composite doors that may seem appealing at first often fail to deliver long-term performance. All generic composite doors on the market today use timber for the door's inner frame. While the quantity and quality of timber may vary, a common issue across these doors is the tendency for the wood to warp, causing the panels to bow. Additionally, these doors typically feature clip-on glazing cassettes. Holes are cut into the door panel to insert the glazing units, which are then held in place with plastic beading that clips or screws together. This design allows the glazing to be removed from the outside, giving an intruder easy access to the home. Two additional concerns are the use of low-density foam in the door’s core and the reliance on poor-quality door hardware, with cost being prioritised over quality. When combined, these issues can lead to a range of problems for homeowners.
Common repair issues we encounter with typical composite doors include:
-
Difficulty opening and closing – Often caused by low-quality hinges that are not designed for the weight/demands of composite doors, as a result over time the door leaf drops and snags on the frame.
-
Total hinge failure – We have replaced countless hinges on budget composite doors due to them sheering/snapping after less than a few years of use.
-
Large gaps between door and frame when closed – This can result in draughts and water ingress, usually due to the door leaf bowing as the internal timber either dries out or swells from water ingress.
-
Failed glazing cassettes – Typical composite doors use plastic clip-on glazing cassettes, which can fail over time due to natural expansion and contraction, the thin mastic seal between the cassette and door 'pops' allowing air and/or water to enter the home.
Our priority is to ensure that the product we install is one the customer can rely on for years to come. We have full confidence in the quality and durability of Rockdoor, which is why we focus exclusively on offering this premium option.
Below is an example of what can happen as result of purchasing a budget composite door.
A customer reached out to us after receiving no response from the company that installed the door.
Their door had been only been installed 3 years prior. The photos that follow illustrate the issues raised.
Among the various issues the customer faced, their biggest concern when contacting us, was the water damage to their flooring caused by recent heavy rainfall. After spending a weekend placing towels and mopping up water from their internal floor, they identified two main sources of the leaks: water dripping down the inside of the door which was coming through the glazing cassette, and more significantly, water pouring in between the door leaf and frame.
After a quick inspection, we first demonstrated that, despite multiple attempts to adjust the lock keeps and hinges to compress the door it into the gasket seals, the door could not achieve a proper seal. We compressed the door so tightly at one point that it was effectively unusable under normal conditions but did so to highlight that the door compression couldn't be improved anymore.
We then performed a hosepipe test in front of the customer, simulating rainfall. We ensured the water wasn’t directed forcefully at the door, but fell naturally, much like rain would. Despite our precautions, water still flooded in.
We were able to clearly show the customer the points of entry where water was getting through. As the door panel had bowed there were visible gaps where the door was no longer sitting flush against the frame and gaskets.
In addition to the bowed panel and leaking cassette, the glazing unit had failed, as evidenced by the condensation visible in the photo below. With no response from the installation company regarding the warranty and unable to escape the water leaks during adverse weather, the customer asked us to replace their door with a Rockdoor. After installation, they were amazed by the difference in quality, not just the in the look and feel of the door but the customer could visually see the difference in build quality.
While the initial price of the previous door was lower, it had ultimately cost them more in inconvenience, damages, stress and the need for a new door—outlays that could have been avoided if they had chosen a Rockdoor from the start.
uPVC Doors
While uPVC doors have become less commonly requested with the rise of composite doors, we recognise that they remain a preferred option for many. uPVC doors can still offer significant improvements in security, insulation and aesthetics, particularly when replacing older timber or early-generation uPVC doors.
Whether you are looking for a new entrance door, a set of French doors, or a sliding patio door, we offer a complete supply and installation service for all uPVC door options.
In today’s market, a high-quality uPVC door is often priced similarly to a budget composite door. However, based on our experience and the factors we've outlined regarding typical composite doors, we have greater confidence in the durability and longevity of uPVC doors.
We are committed to only offering high quality products, as this aligns with our values. We believe in providing solutions that will stand the test of time and not cause issues for our customers in the future. If a customer is working with a more limited budget and seeking a cost-effective solution, we would recommend a uPVC door. While it does not offer the same level of performance as a Rockdoor composite door, it provides good value for the price, balancing affordability with quality.
