Modern PVC and Composite doors are strong and secure giving you piece of mind and loads of kerb appeal.

PVC Doors have come a long way from the early PVC doors that suffered from colour fade. With a choice of colours and styles, modern PVC doors are smart, secure and long lasting.

Composite Doors are for those that love the traditional style and colours of painted timber doors but want the efficiency and security of a modern door. With a long lasting finish we are sure that these doors will still look like new for many years to come.

French Doors, Patio Doors and Bi-Fold Doors

There is no better way of bringing the delights of the outside into your home than with stylish glass panels of modern French,  In-Line Sliding Patio doors or vogue Bi-fold doors.

We offer a one stop shop for your new conservatory. The surveyor who comes to discuss and take preliminary measurements may well be your point of contact, fitter and finisher throughout the build.


Fascia, Soffit and Guttering

Often called the roof-line,  an important but often overlooked area of your home.

Fascia is the flat vertical board on your roofline that your guttering is attached to.  It also forms a weather barrier between the elements and the timber structure of your roof.  Poorly maintained fascia can lead to expensive roof repairs.

PVC Fascia comes in a number of widths and with a wide range of colours and finishes.

Soffit sits horizontally at the roof line, closing the gap between your roof and your walls.

Soffit is available in a decorative tongue and groove style board or a sleek and sharp flat panel.

Guttering Delta stock the Kalsi Aquaflow Guttering System.  We also use Aquaflow guttering components for our own installations.

You have the choice of the soft lines of a Round profile, decorative contours of Ogee or clean straight lines of the Square profile.  All ranges are held in stock in Black and White (Brown available to order).
