Luckily, this doesn’t involve much hard work, and you won’t need any special equipment either. It only needs a spare half an hour on a lazy weekend and you’ll be able to keep your front door clean and in good condition. It won’t just look nice, it’ll potentially add years to its lifespan. 

So with that in mind, here are a few things you can do to keep your composite door at its best.

How To Clean A Composite Door

Let’s get the easier part out of the way first; cleaning your front door. This is one of those odd little jobs you can do to keep your house looking nice, so it’s worth adding it to your regular home cleaning routine. 

All you need to do is take a bucket of warm soapy water, and use a sponge to clean any dirt off. Start from the top and work your way down, then rinse the soap suds off once it looks clean. The only thing to remember is don’t use abrasive scrubbing brushes, chemical cleaners or bleach; they’ll potentially scratch or damage the surface.

If your composite door has windows fitted, use a glass cleaner to get them spotless. Don’t forget the hardware either; use warm water and mild detergent to wipe clean any letterplates, handles or knockers.

Routine Maintenance

Aside from keeping your door clean, you’ll also want it to perform well. Sometimes people get intimidated by this but don’t worry. General maintenance is easy, so you can stop worrying about loosening the wrong screw and the door falling off.

The main thing to remember is to lubricate the mechanisms. You only need to do this once every six months or so, but it’ll ensure that the door glides open smoothly. Use a light engineering oil to lubricate the hinges, handles and letterplates and it’ll reduce friction in the mechanism. Whatever your well-meaning relative might tell you though, don’t use WD-40. It dries out too quickly. While you’re doing this, check the weather seals haven’t slipped from their grooves and slide them back into place if needed.


Clean and Long Lasting Composite Doors

If you make cleaning and maintaining your door part of your routine, you’ll add years of life to it. It’s only a small amount of effort and it can make a big difference in the long run.

How Are Composite Doors Made?

17 Laminations

Our composite doors are made up of 17 laminations with a solid timber core. We use BBA accredited, engineered LVL (laminated veneered lumber.). Our 48mm thick core offers exceptional stability and eliminates the possibility of warping over time. Each door is manufactured with an integrated Moisture Barrier System in the base of the door which protects your door from water damage, delamination and maintains its integrity, avoiding common problems with composite doors.


Door Skin

Endurance composite doors feature a laminated door skin with a highly weatherproof and durable acrylic layer, offering exciting vivid colours and luxurious wood effect designs that perfectly match the door frames into which they are installed. Our replacement front doors are finished with a foiled 3D Cool Skin that features an embossed woodgrain texture to offer a surface that won’t crack or fade. Available in 16 colours ranging from neutral shades to bold bright tones, you can create a composite door solution that is colour lasting and will continue to look great even after years of use. Once you’ve selected the style, and design of your new door and applied your preferred colour you can add finishing touches to your composite door with a wide selection of hardware and security options. Select from handles, knockers and letter plates to personalise your door and make it your own.

Hardware Options

With 10 hardware colours to choose from including Gold, Graphite, Antique Black and Chrome you’ll be spoiled for choice when it comes to putting the final touch to your composite door. Created to blend into the surroundings of your property and to complement your existing décor, we know that you’ll be pleased with the finished result.

what are the benefits of the solid timber core external doors

Solid Timber Core

The Endurance door has a solid core unlike others. This robustness means there are more advantages and far fewer problems with composite doors from us compared to other companies.

With 48mm thick cross-bonded veneered laminated timber door lead, Endurance composite doors deliver lateral strength and unrivalled stability.

We use Kerto LVL for our solid core, a material which is incredibly strong and dimensionally stable timber beam. The makeup of our solid core is designed so that it can be cut to any height or width without affecting its integral strength.

Our solid core competitors use cores that incorporate less dense mixed species woods with a stile and rail subframe. The core’s strength comes from the outer subframe in these doors. A narrow or short door involves cutting into this subframe and cutting away the strength of the door. These doors don’t always hold their shape when facing the temperature changes of British weather and central heating.

We are so confident in the quality of our Endurance composite door we offer a 3mm bowing guarantee on our doors.
