Most timbers can be used. We use Door World as a supplier, just reference Beeline Carpentry and we have fixed prices to hang doors which can be quoted over the phone. He fitted a new front door for us and repaired our door frame as well as numerous smaller jobs we are not skilled enough to do properly. 100% recommend and he is coming back to make us an airing cupboard later in the year! Such a great guy and amazing work for us. He's built a beautiful under stairs storage cupboard and we couldn't be happier.
