The majority of customers seek a ‘no fuss’ door solution, so it stands to reason that prehung doors are the first choice for busy door installers. Amongst their many benefits, prehung door sets implement a faster fitting process which inevitably increases sales and productivity.
To help you get the job done right first time, we thought we’d share our top tips on installing prehung exterior doors below.
Correctly order to fit the aperture
It sounds incredibly simple, but if you get new door measurements wrong you won’t even get out of the starting blocks, let alone fall at the first hurdle! So, be sure to double or even triple-check your door measurements before giving them to your door supplier.
Shim before installation
During the levelling process, shims (or wooden wedges) help to brace the door jamb and provide crucial nailing support. Shims work by sliding in until they fit comfortably between the jamb and the frame. After the jamb has been centred, level and shim the door on the hinge side only; between the jamb and the rough-in frame. Additional shimming may be required behind, above and below the strike plate. Once you’re happy with the door’s alignment, cut off the ends of the shims for a smooth finish.
If the flooring hasn’t been installed beyond the door threshold yet, shim beneath the door jamb to account for the height added once the floor is installed. Doing so will eliminate future clearance problems.
Plumb, level and square
Avoid common issues like sagging, unwanted opening or closing and hinge binding, by making sure the door is correctly aligned.
Plumb prehung door
Using a full-length spirit level on both side jambs and the outer edge of both jambs, make sure the lock side and the hinge side have true vertical alignment.
Level prehung door
Check the top jamb and threshold sill to determine whether the door has true horizontal alignment.
Square prehung door
Using a tape measure, measure from where the threshold sill and side jamb meet, up to the opposite top corner where the side jamb meets the head jamb. Record the measurement. Take a second diagonal measurement from the opposite corner, corner to corner. If the measurements match, the door is square; all four corners are at perfect right angles.
Source a specialist trade door supplier
You rely on your door supplier to promptly deliver quality products that are competitively priced. You need to keep your existing customers loyal and happy, attract new clients and keep your options open to the possibility of entering new markets. If your current trade door supplier is falling short of just one of these fundamental goals, it is in yours and your client’s best interests to switch suppliers sooner rather than later.
