Solidor Doors vs Other Composite Door Brands

Have you been looking for a new composite door? We know how hard it is to set each brand apart from one another. We want to help you decide the right composite door for your home.

The term ‘composite door’ is well heard of within the industry, however, do we really know what a composite door really means? No two composite doors are the same across the industry, with different colours, finishings and cores. So, we have created a comparison between Solidor, Endurance and other top composite door brands to help you find the perfect door for your needs.


What is a composite door? A composite door is made up from a variety of materials, which can include uPVC, wood, insulating foam and glass reinforced plastic. When combing these materials together effectively, a strong and highly secure composite door is created. However, the wrong combination of material or low quality materials will create an inferior door. Composite doors vary across the industry, and no two composite doors are the same.

Endurance Composite Door

The Endurance composite door has a solid timber core that is made up of 17 crossed layers of laminated veneer lumber, making it the strongest and most durable composite door on the market. A unique moisture barrier strip is also enclosed in the bottom of the door, stopping water ingress that can lead other composite doors to swell or warp. Finally, the tough skin that is used to give an Endurance door it’s authentic timber-like appearance has been specifically designed to reflect up to 95% of the heat from the sun. So the coloured skin of an Endurance door won’t fade or crack no matter how hot the British summertime gets.

Solidor Composite Door

A Solidor composite door also has a solid timber core, but is made up of far fewer wooden layers. This coupled with the lack of a moisture barrier strip in the bottom of the door makes a Solidor more susceptible to both bowing and warping. Solidor composite doors have been firmly established in the industry offering a composite door that is unlike others for their sophistication and performance. However, after looking into Solidor’s reviews, we found a mixture of both good and bad reviews, mounting to an average rating of 3 stars on their Trustpilot page.

What other Types of Composite Doors are there?

Not all composite doors are made equal. Under the term ‘composite doors’ there are variety of different products on the market.
Whilst both Endurance and Solidor are famed for their solid timber core, there are also composite door manufacturers who produce composite doors with a core made out of high-density polyurethane foam. Whilst these types of composite doors can be energy efficient, they cannot be compared with the quality and level of security offered by a solid timber core composite door.

Always check to make sure that when comparing composite door products that you pay attention to not only how the door looks, but also what it is made from and how it is constructed.

Endurance Composite Front Door


  • Endurance Solid Timber Core

    With Endurance 17 lamination layers made from Kerto laminated veneer lumber. The Endurance door layers have been designed this way to provide the door with the level of solidity to its timber core. The solid timber core ensures our composite doors are resistant against bowing or warping. The Endurance door slab has a bowing tolerance of just 3 millimetres. This means that if your door were to bow even slightly, we would replace your door slab free of charge.

    Endurance doors are one of the, if not the heaviest door on the market, making them the sturdiest and most secure composite door.

    The Endurance composite door has a unique moisture barrier system that prevents moisture build-up, which helps to protect the solid timber core from bowing, warping or swelling.

  • Solidor Solid Timber Core

    Solidor measures the same 48mm thickness as Endurance. However, they only provide 3 layers of lamination. Solidor composite door slabs have a significantly higher bowing tolerance with 10 millimetres of bowing.

    When browsing through Solidor’s reviews on Trustpilot, we found a customer who had the unfortunate incident of having an issue with their door. Labelling Solidor products ‘terrible’:

    “Terrible product. 4 composite front doors have failed (Bubbling / Warping). Technician sent out by Solidor for the 4th door verbally agrees on site that the door is faulty then Solidor report that its within tolerance… stitch up merchants. Do not touch with a bargepole.”

    Whereas other customers “Love my Solidor”.

  • Other Brands

    Many other brands of composite doors provide a core that is made from soft timber or even a high density polyurethane foam. These cores can be enough in providing your home with a solid, durable door. However, with a softer core, the door is automatically more vulnerable to break-ins.

Solidor Composite Door Reviews

Solidor has a wide range of reviews that have both positive and negative feedback, giving them their overall 3 star rating on Trustpilot. Solidor appears to not have an in between, they are either well received or cause an unhappy customer.

Solidor has ‘5 stars all round’ with some of their happy customers:

“5 Stars all round! Really happy with the whole experience. The quality of the door is exceptional, as was the service from Phil Homans for the installation and after sales service. Overall a real 5 Star experience.”

Whereas others were left unhappy with Solidor’s services, failing to help them improve a faulty lock:

“No thanks to Solidor but my door locking is finally fixed. Door fitted in August and took 3 months and 4 visits from Solidor with no success then my installer, Select Windows, put in a different manufacturers lock barrel and the door has worked ever since. Very disappointed in Solidor and they are not even offering proper compensation for all my time wasted and worry. Love the door though.”

Endurance Composite Door Reviews

Although Endurance is a lesser-known brand, we have extremely positive feedback from our customers.

“Andy came out and surveyed, and took me through the many choices available from Endurance. I chose an Enta, which is a design similar to what I had, mainly because I loved my old failing door. I’m amazed at the difference in security and quality of my new door. It has a solid timber core and high security locking mechanism. The door is extremely sturdy. I’m thrilled with my door and the entire experience. The 10 year guarantee gives me complete peace of mind.”

Abbey Windows, a reading-based installer have been long standing Endurance customers. The managing director offered his thoughts on Endurance composite doors in his interview where he stated he would recommend other installers to join Endurance preferred installer network:

“Yes, I recently recommended Endurance on our Reading Trade Windows Facebook page. It was all because of the reasons I’ve just given. We had a gentleman, who buys about ten doors a month, who was having problems with a different solid core door manufacturer. The last 8 out of 10 doors that were delivered had a 6mm bow in the slab, which they were not addressing. I recommended the Endurance door design because its inherent strength bypasses this problem. Also, if we have had other problems, Endurance has always addressed them.  It’s fantastic to have that support.”


  • Solidor Composite Door Security

    Unlike Endurance, there is no little evidence to back up the durability of their doors. Solidor reassures homeowners that their composite doors are arguably the most secure on the market.  There is evidence to prove the durability of their doors with their Secured by Design certification.

    However, one customer found they had to call out Solidor for 4 different lock issues:

    “I have had my Solidor or just under 2 years and I have to say that after spending a substantial amount of money I would not recommend this brand at all! I have had 4 site visits for lock issues and most recently warping issues which solider, wait for it, say they can warp up to 6mm either way! …. As mentioned the door had warped in the centre on the this occasion due to the heat we had in the summer but now we have a warp at the to of the door due to the cold setting in, Fantastic! My installer agrees that the door has an issue but solidor has the cheek to say its an installation issue. Please do not waste your hard earned money on what they say is a premium product.”
