Fitting laminate neatly around door frames is the detail that separates a professional-looking floor from an amateur one — and it is entirely achievable for a skilled DIYer or a flooring tradesperson working in homes, holiday apartments, or hotel rooms across Greece. The video above from DFD walks through the cuts in real time; the guide below gives you the reasoning behind each step so you can adapt it to the frames and doorways you actually face. No building permit or licensed contractor is required for laying laminate flooring, but if the subfloor shows signs of damp — common in ground-floor properties and older Greek buildings — address that first before any boards go down.
Why Door Frames Are the Hardest Part of a Laminate Job
Laminate boards are rigid planks, not flexible sheet material. Getting them to wrap around the legs of a door architrave (the decorative trim) and under the door jamb (the structural surround) requires a combination of two distinct cuts: an undercut into the jamb so the board slides beneath it, and a notch in the board itself to navigate the protruding corners of the architrave. Skip either cut and you end up with visible gaps or boards that simply will not seat flat.
In Greece, door frames are frequently solid wood set in plastered masonry walls, which means the jamb is thick and the architrave can stand proud of the wall surface by 10–15 mm. Always measure your specific frame before cutting — do not rely on generic dimensions.
Tools and Materials to Gather Before You Start
You will need: a pull saw or oscillating multi-tool for undercutting the jamb, a jigsaw for notching the board, a tape measure and pencil, a combination square, a piece of scrap laminate or underlay to use as a depth gauge when undercutting, and appropriate PPE (safety glasses, dust mask — laminate dust is fine and irritating). A padded mallet and a pull-bar are useful for seating the notched boards without cracking the locking tongue.
Keep the expansion gap in mind throughout. Standard laminate requires a minimum 8–10 mm gap from any fixed vertical surface, including door jambs and architraves. This gap will be hidden under the door stop or a slim skirting/beading once the floor is complete.
Step-by-Step: Fitting Laminate Around a Door Frame
- 1
Undercut the door jamb and architrave
Lay a piece of scrap laminate flat on the subfloor and place a piece of your underlay beneath it to replicate the finished floor height. Hold your pull saw flat on top of this stack and saw horizontally through the bottom of the jamb and architrave on both sides of the doorway. Work slowly — you need a clean, level cut just deep enough for the board to slide under without rocking. Remove the offcut timber debris and vacuum the channel clean.

Mark the notch on the board
Slide the board into the doorway opening until it touches the jamb. With a pencil, mark the exact width of each architrave leg on the face of the board. Then push the board forward so its end butts against the jamb and mark the depth of each architrave leg along the board's length. You now have a rectangle drawn on each corner of the board that represents the material you need to remove.

Cut the notch with a jigsaw
Clamp the board securely and make two cuts per notch with a jigsaw fitted with a fine-tooth blade: one cut along the length of the board (parallel to the long edge) and one cut across the width. Remove the small offcut. Test-fit the notch around the architrave — it should slip over cleanly with 1–2 mm clearance on each side to allow for seasonal movement. Do not force a tight fit; laminate expands in humidity, and Greece's summer-to-winter humidity swings are significant.

Engage the locking joint and seat the board
Angle the notched end of the board slightly upward and slide the tongue-and-groove long edge into the previous row's groove. Once the tongue is engaged along the full length, lower the board flat and gently tap the notched end forward using a pull-bar until the short-end joint clicks fully into the adjacent board. The notched section should now sit under the undercut jamb with the board lying flush. Check with a straightedge that no corner has lifted.

Fit the door stop and check clearance
Refit or install a new door stop strip along the base of the jamb — this thin strip of timber or MDF covers the undercut scar and any small gap at the jamb. Check that the door itself still swings and latches without catching the new floor surface; with the underlay and board in place the floor is typically 10–12 mm higher than the old subfloor, so you may need to plane or saw a few millimetres from the bottom of the door. Mark the new cut line with the door closed against the floor, remove the door from its hinges, and trim with a circular saw using a guide batten for a clean straight cut.

FAQ
- Do I need to remove the door to fit laminate underneath it?
- Not always, but it makes the job considerably easier. With the door on its hinges you cannot slide long boards through the opening freely, and you risk chipping the board edge on the door bottom. Lift the door off its hinges, lean it safely against a wall, complete the laminate in the doorway area, trim the door bottom if needed, and rehang. The whole detour adds about 20 minutes but saves you from poor cuts and lifted corners.
- Can I just cut the laminate to fit tightly around the frame without undercutting?
- Technically you can cut a notch that wraps around the outside of the architrave, but the visible joint line will be obvious and you will have no room for the board to expand. Over time, especially in coastal or island properties where humidity varies widely between seasons, boards without undercut clearance can buckle upward against the fixed frame. Undercutting the jamb is the industry-standard solution precisely because it hides the joint and gives the board room to move.
- The subfloor under my doorway is uneven — does that matter?
- Yes, significantly. Laminate relies on a flat, rigid base; even a 3 mm dip or hump under the doorway area will cause the locking joint to flex under foot traffic and eventually fail. Use a feather-finish levelling compound to flatten any low spots and grind down high spots before laying underlay. In older Greek buildings, threshold transitions between rooms often conceal uneven screeds — check with a long straightedge before starting and allow the compound to cure fully (typically 24 hours) before laying boards over it.
