Back Doors

Back doors might not always be as immediately obvious to callers at your home – but just like front doors they need to be practical, secure and good-looking.

Our uPVC doors and composite doors won’t warp or rot like wood does. They will never need re-painting and they can be cleaned with just a quick wipe.

All Coastline Windows back doors can be made in a range of finishes with matching half panels and a choice of clear or obscure glass designs.

Door handles can also be supplied in a selection of finishes to provide the perfect finishing touch.

All our doors boast the latest security locking features – as we are aware that crime statistics from the Home Office show that 67% of burglars break in through an outside door.

We work closely with the police under the ‘Secure by Design’ scheme to ensure our customers enjoy maximum peace of mind.

Our doors boast a state of the art 10 point locking system and three opposing steel hooks to maximise strength. There are also two anti-lift bolts stopping the door from being dislodged and four pre-compression rollers allowing the door to seal shut before the hooks engage. This keeps it operating smoothly.

There is also one centre latch for easy day-to-day operation which incorporates dead-lock action when the bolts and locks are engaged for even more security.

Glazing options include square leaded, diamond leaded, patterned and stained.

Solid colours available for back doors include white, black, green, cream and red. You can also choose a woodgrain finish if you prefer – which may customers say looks just like real timber. Handles can be provided in gold, chrome, white and black to fit the look you want to create.

A similar range of great looking and high performing patio doors, French doors and garage doors are also available from Coastline Windows.

Low maintenance is a huge advantage of our modern replacement doors, but you can also take advantage of our windows and doors MOT to ensure they last and last in great working order.
