What does a prehung door include?
Fit the complete frame as a supported, aligned unit before concealing the opening with casing. A prehung interior door is a door slab already hung in its frame. Identify the unit, check for transit damage and confirm the swing before removing the old frame. OPPOLIA’s prehung-door buying guide distinguishes hollow-core, solid-core, wood and MDF choices, and primed versus finished surfaces. Confirm the selected product’s fastening schedule; a barn-door arrangement or pivot system needs its own instructions.
- What is the rough opening?
- The rough opening is the framed space in the wall that receives the complete door frame. It is different from the door slab size and from the clear passage left when the door is open.
What should you measure before removing the old frame?
Measure the actual opening width and height, the wall depth that the jamb must cover, and the finished floor position. Check the diagonals for squareness, each side for plumb, the head for level, and the faces for twist. Use the unit’s dimensions and correct unsuitable framing before dry-fitting.
The JELD-WEN JII109 interior pre-hung instructions reproduced by Lowe’s say the frame width and height should each be 1/2 inch smaller than the rough opening. That is a frame-to-opening allowance in this particular document, not an allowance to add to the slab. JELD-WEN also gives a 1/4 inch maximum difference from square and a 1/8 inch maximum plumb deviation. Confirm the instructions supplied for your actual unit before using these figures.
Why do online size recommendations differ?
Indigo Doors’ step-by-step tutorial uses a different opening example and recommends its own screw lengths and spacing. Those figures are not interchangeable with JELD-WEN’s frame-based allowance. Do not combine a slab-size example, a frame measurement and a fastening schedule from different products. Confirm the reference dimensions with the supplier before cutting.
Metrie’s door guide includes marking hinge positions and routing mortises. Those steps concern fitting a slab; a complete prehung assembly already has the slab hung in its frame. Metrie’s hinge-position measurement is therefore not a layout rule for this prehung-frame procedure. An exterior pair also adds weather protection and meeting-door details: use the separate guide to exterior pairs when that is the actual job.
Which tools and preparation belong on your checklist?
Gather a tape measure, a level, shims, the specified fixing tools, and the protective equipment required by the work. Check the supplied fixing and finishing instructions before buying screws, nails or sealant. JELD-WEN recommends a level at least 4 ft long in its JII109 document. Check the jamb along its full length.
JELD-WEN requires at least two people and adequate support until the unit is fully fastened. Protect the slab and glass during handling. Follow tool safety instructions and check the appropriate precautions before disturbing suspect old paint. JELD-WEN’s acclimation guidance belongs to its specified products; finishing readiness and total working time depend on the unit and conditions, so no universal duration is promised here.
How do you set and support the frame?
Prepare a clear working area and protect the finished floor. Remove the shipping restraints at the stage required by the supplied manual. Bring the supported unit into the opening, then establish the hinge-side jamb first. Use the level along its length and check its face, not just its edge. Place shims where the specified fixings need solid support so tightening does not pull an unsupported jamb toward the stud.
Next set the opposite jamb and check the head. Keep the frame untwisted and the visible clearance between the slab and frame consistent. Open and close the supported door as the manual permits, adjusting the shims before final fixing. If the opening needs structural correction, stop fitting and have the framing assessed. A distorted opening is not something to conceal with trim.
How should you choose fixing locations?
Follow the selected frame system’s schedule. JELD-WEN’s JII109 document describes 10d finish nails and fixing through the stop, jamb and shims into the studs every 12–16 inches. It separately describes 4d nails for trim. Its provided #9 x 2-1/2 inch hinge screws apply only to the door constructions identified in that manual. Use these examples only for the specified products.
The Home Improvement question on concealed fixing asks how to avoid visible holes on an interior jamb. In the single answer, crip659 suggests carefully removing and replacing a removable stop to hide fixings. The question’s screw lengths and the comments’ estimates of stop and nail dimensions are individual suggestions, not a verified schedule for your unit. Confirm that the stop is removable and follow the frame maker’s method; forcing a fixed stop can damage the assembly.
When should you test the door and add trim?
Test movement before concealing the opening and again after final fixing. The door should move without rubbing, the latch should meet its strike, and the visible clearances should remain consistent. If tightening changes the gap, check the support and alignment before adding more force.
Fit the casing only after the door operates correctly. JELD-WEN distinguishes one-piece and two-piece jamb systems; follow the correct sequence for yours. Sealant composition and finishing instructions also belong to the selected frame system; JELD-WEN specifies its own two-piece-frame treatment. Follow the product’s instructions for jamb trimming, under-door ventilation clearance and finishing the slab and frame. Do not substitute generic clearances or sealants.
How do you coordinate the room door with Fadior cabinetry?
Check the room door’s swing against storage, drawers and furniture. Mark their opening zones together. Compare the black and white door choices beside the actual wall and cabinet finishes, then use the whole-room space options to consider where storage belongs.
Fadior’s Foshan manufacturing information and production record describe fabrication, assembly, checking and packing. Fadior kitchens, wardrobes, baths and storage systems use 304 stainless steel cabinet bodies; room doors, fronts and finishes follow their own specifications. Confirm the scope of the actual doorway order separately from the cabinetry package. Use the Fadior company overview and current Fadior design collections to compare surrounding cabinetry.
| Decision | Record before fitting | Reason |
|---|---|---|
| Room door | Unit, frame depth, swing and supplied instructions | Keeps the door maker’s fixing method attached to the selected unit |
| Fadior storage | Cabinet-body specification and each front’s finish | Separates cabinetry material facts from room-door requirements |
| Shared room | Door swing and storage opening zones on the same plan | Lets both installers check clashes before trim hides the opening |
| Handover | Unit label, supplied manual and final operation checks | Leaves the fitting record available for later adjustment |
What can a delivered home show you?
Fadior’s photographed Real Homes collection includes Curved Fitted Wardrobes in a London Villa, with entryway, walk-in closet, wardrobe and kitchen spaces listed. The listed rooms show a connected cabinetry plan. Confirm the actual door model separately. Discuss circulation and storage together; use the door’s documents for fitting details.
The Instagram result highlights checking the opening and setting the hinge side plumb. The YouTube titles describe hanging prehung doors, including a JELD-WEN cabin example. Their available text supplies no complete fixing schedule. Use the supplied manual for measurements, fastenings and support.
What should you record before handover?
Keep the label, manual, finish instructions and final checks together. Recheck that the room door and adjacent storage can open as intended with furniture in place.
For a cabinetry project around the doorway, use the Fadior project enquiry form. Name, email and phone are required; the form also offers optional country, project type, budget range, company and message fields. Describe the room, destination country, timing and available drawings or site photos in the message. Confirm room-door and cabinetry responsibilities separately.
What belongs in the fitting record?
- Selected unit: Keep the door label and supplied manual together.
- Opening: Record corrections made before fitting the frame.
- Operation: Record the final swing, latch and adjacent-storage checks.
Which prehung-door questions do buyers ask most?
Use the selected unit’s documentation for the final decision. These answers distinguish purchase scope, opening size, working time and fitting checks.
