A quick, efficient and speedy response. Well fitted and instructed. Would recommend. 

- Mrs N. New Romney


We are Kent's leading exterior door specialists and have been supplying and installing doors throughout the county since 2006.

We have hundreds of satisfied customers who have benefited from our straightforward ordering process. You only have to deal with one person from discussing your order options through to the installation of your new uPVC or composite door. This enables us to keep costs down (no salesman’s commission or survey fees) and give a personal service throughout with great quality control. These benefits are passed on to you, the customer, ensuring excellent value for money and satisfaction.

Please take the time to look around our unique one-stop door shop. Where else will you find such a wide selection of styles and designs? Where else will you see fully inclusive FITTED prices online? There is no catch, no hassle - just top quality doors at sensible prices, expertly fitted! Please note that the range of colour and glazing options for Composite doors is huge. We have shown a selection of the most popular ones to hopefully give you a rough idea of what is available.

The simple 3 stage process to a beautiful new uPVC or Composite door at a sensible price!

Step 1

Browse our website (click on "products" at the top of the page), choose the style of door you like, click on the door and you will see the full range with fully inclusive FITTED prices. The price INCLUDES letter plates, knockers and lever handles as shown in the relevant picture. VAT has also been included. Please note that we have only been able to illustrate the most popular doors and that, in addition to these, there are many more glazing, colour, and style combinations to choose from. Please call or email for a quotation if your specific requirement is not shown.

Step 2

Phone your local area number to be put in touch with the fitter for your area, or email This email address is being protected from spambots. You need JavaScript enabled to view it. (click on "contact us" at the top of the page). We will make an appointment to visit you at your convenience (evenings no problem) and carry out a free site survey for your new uPVC door or Composite door. If you are ready to place an order we will book a fitting date with you there and then (usually within 10 days). In most cases no deposit is required.

Step 3

Your local fitter will return as arranged to fit your new door at a time convenient to you, he will dispose of your old door and frame etc. Only when the work is complete and to your satisfaction will you be asked for payment. A full invoice and 10 year (dependent on the final specification) guarantee will be provided on completion of the installation and a CERTASS certificate will be sent to you, which covers the requirements of the Building Regulations.

Quotations and advice are free of charge and without obligation. Our usual home survey takes no longer than 20 minutes and we really don't mind if you want to think it over before placing your order. We guarantee NO HARD SELL!

All prices quoted are fully inclusive for the product shown and there are no hidden extras. Fitting, measuring, delivery and disposal of your old doors are all included, as are the following options: frosted glass, door knockers, letterboxes, and door handles in your choice of finish (chrome, gold, black or white). The price you see really is the price you pay.
