Door Fitting

Once we have your door back from the factory we will meticulously inspect it to make sure it passes our quality standards before we confirm your preliminary fitting date.

On the fitting day we will work quickly to remove your old door and door frame. We will then install your new door frame and door with new seals and trims to your satisfaction.

Composite doors
Preferred choice

Composite doors are the preferred choice of double glazed external doors for many homeowners and tradesmen due to the many advantages that composite doors have over the alternative wooden doors, steel doors, upvc doors and most other external doors available. Composite doors are more durable and stronger making the doors more secure. They have greater thermal efficiency, are weather resitant and low maintenance expanding the life of your composite door.

We recommend all external doors are fitted with Anti Snap Locks

  • New Doors

    I called Shefflock after being locked out of the house due to ongoing warranty issues with the front door since buying my new build house. Chris gained access and rectified the lock issue rapidly. I got the impression that Shefflock genuinely value their customers, are polite and treat you with respect. Needless to say that I've found my reliable local 'go to' Locksmith!
