Door Installation Guide India: Fix the Frame, Hang the Leaf, Fit the Lock

A door that binds in the monsoon, scrapes the floor, or never quite latches is almost never a bad door — it is a badly installed one. Get the frame plumb and square, hang the leaf on three properly mortised hinges, and set the gaps right, and even a modest flush door will swing sweetly for twenty years. This guide walks through exactly how a door goes into an Indian home, in the order a good carpenter actually does it: frame first, then leaf, then hardware, then the final adjustment and seal.

The two halves of the job: frame and leaf

Every door installation is really two jobs. First you fix the frame — the chowkat, in most of north and west India, or the door frame more generally — solidly into the masonry opening so it is dead plumb (vertically true) and square (corners at 90°). Then you hang the leaf (the shutter, the part that swings) on hinges and fit the lock, handle and stopper. If the frame is wrong, nothing you do to the leaf will save it. So the frame stage is where you spend your care.

In new construction the frame usually goes in before plastering, so the holdfasts get buried in the masonry and the plaster finishes flush to it. In a renovation or a replacement, you are fitting a new frame into a finished opening, which is fiddlier and where most DIY attempts come undone. Either way the sequence and the checks are the same.

If you are still choosing or sizing the door, read how to measure a door first — installation assumes the leaf and frame already fit the opening with the right allowances. For what the frame itself costs, see door frame cost in India, and for whole-job pricing, door installation cost in India.

Step 1 — Fix the frame (chowkat) plumb and square

This is 60% of the job. The frame must be vertical on both jambs, level across the head, square at the corners, and rigid in the wall.

Stand the assembled frame in the opening. Most timber frames are sold pre-assembled with the head joined to the two verticals; a cheap one you may have to join yourself with corner blocks or dowels. Brace the frame diagonally with a batten or two screwed across the corners so it cannot rack out of square while you work — this temporary cross-brace is the single most-skipped step in amateur installs.

Now level and plumb it:

• Set a spirit level against each vertical jamb and shim behind the frame until both read true plumb. Use wooden wedges or hard packers, never crumpled paper or foam.
• Level the head across the top.
• Measure the two diagonals corner-to-corner; when they are equal, the frame is square. Adjust shims until they match.

Then fix it into the masonry. Traditionally Indian timber frames are anchored with holdfasts (MS flat hold-fast clamps, usually three per jamb) that are set into the wall and grouted with cement mortar — this is the method when the frame goes in before plastering. For a frame fitted into a finished opening, you instead drill through the jamb into the masonry and fix with frame screws and wall plugs (rawl plugs), 3 to 4 per side, then fill the gap between frame and wall with PU foam or non-shrink grout. Keep checking plumb after every fixing — tightening a screw can pull the frame out of true.

Timber frames should follow IS 4021 and steel frames IS 4351 for dimensions and fixing — worth quoting to a carpenter who wants to short-cut the holdfasts.

Step 2 — Hang the leaf (mark and fit three hinges)

With a true frame, hanging the leaf is straightforward. Indian residential doors almost always use three butt hinges (4-inch / 100 mm for internal doors, often 5-inch for heavy main doors) — top, bottom and one in the middle, biased slightly toward the top where the load is highest. Two hinges sag; three is the standard. For the hinge sizing and types, see door hinges guide.

The sequence:

1. Position the hinges. Top hinge about 150-200 mm from the top of the leaf, bottom about 200-250 mm from the floor, third roughly centred (or a touch high). Mark their positions on the leaf edge and transfer the exact same marks to the frame.

2. Mortise (recess) the hinge leaves. Chisel out a shallow recess so each hinge sits flush — if a hinge stands proud, the door won't close; if cut too deep, the gaps go wrong and the door "hinge-binds." A trim router speeds this up but a sharp chisel and patience do it.

3. Screw the hinges to the leaf first, then offer the leaf up to the frame with a couple of packers under it to hold the floor clearance, and screw the other hinge leaf to the frame. Drive one screw per hinge, then test the swing before committing all the screws — it is far easier to adjust now.

4. Check the swing and clearance. The door should swing freely, stay where you leave it (not drift open or shut — that betrays an out-of-plumb frame), and clear the floor by 8-12 mm (more over tile or rugs). Aim for an even 2-3 mm gap down the hinge and lock sides.

Step 3 — Fit the lock, handle and stopper

Now the hardware. On most Indian doors this means a mortise lock (a lock body recessed into the leaf edge) with a lever handle set, fitted at roughly 900-1000 mm from the floor — comfortable hand height. For the lock choices, see mortise locks.

• Mark the lock body position on the leaf edge, drill and chisel the mortise pocket, then drill the spindle and cylinder holes through the face. Fit the lock body, then the handle/rose plates on each side.
• Fit the strike plate on the frame so the latch and deadbolt land cleanly into it. Close the door slowly and mark where the latch touches — that's where the strike-plate mortise goes. A misaligned strike is the classic reason a door "won't latch."
• Fit a door stopper — floor-mounted or wall-mounted — so the handle never slams into the wall and the leaf doesn't over-swing. A magnetic catch or stopper also holds the door at rest. See door stoppers.

Match the finish of lock, handle, hinges and stopper (satin nickel, antique brass, matte black) so the door reads as one piece — mismatched hardware is the cheapest way to make a good door look cheap; see door hardware finishes. For the bigger picture of every fitting, the door hardware guide is the overview.

Step 4 — Align, adjust the gaps, and seal

The final 10% is what separates a fitting that lasts from one you'll call the carpenter back for.

• Set the gaps. An even 2-3 mm reveal down both vertical sides and across the top; 8-12 mm at the floor. If one side is tight, shave or re-mortise the hinges (a shim card behind one hinge swings the leaf the other way).
• Allow for the monsoon. Timber and unsealed flush doors swell in humidity. A door fitted dead-tight in a dry March will bind and stick by July. Leave the gaps on the generous side of the range, and seal the leaf edges — especially the top and bottom — with primer or sealer so they don't drink moisture. This single step prevents the most common Indian complaint of all: the door that won't shut in the rains. See door seals and weatherstripping for gaskets and bottom seals.
• Check the hand. Confirm the door opens the way the room needs (into the room, against a wall, not blocking a switch or another door). Getting the hand wrong — hinging it on the wrong side or swinging it the wrong way — is a costly mistake that means re-mortising everything.
• Final seal and finish. Caulk the frame-to-wall joint, touch up paint or polish, and oil the hinges.

DIY or hire a carpenter?

The honest line: fitting hardware to a door that already hangs well is reasonable DIY; setting a frame into a wall is not. A good carpenter sets a frame plumb in minutes that would take a novice an afternoon to get wrong. Fire-rated and security doors must be installed to spec or they lose their rating — that is never DIY.

Tools you'll need

Spirit level (a good 600 mm one), measuring tape, try-square, drill + bits, screwdrivers, sharp chisels (12 mm and 25 mm), mallet, hand or trim router (optional but speeds mortising), shims/wedges, pencil and marking gauge, hacksaw, PU foam or non-shrink grout, and a helper — a leaf is awkward and heavy to hold plumb alone.

What fitting labour costs in India

Hardware and door prices aside, fitting labour is usually charged per door or per day. Indicative 2026 ranges, varies by city and vendor:

Many vendors bundle "supply and fix," where fitting is included in the door price — confirm whether the quote includes the frame, hinges, lock and labour or just the leaf. GST (18% on hardware and most fitting) applies. For full job estimates use the door cost calculator, and to confirm sizing before you order, the door size calculator.

Common mistakes to avoid

• Frame out of plumb or square — the root of almost every later problem; brace and check diagonals before fixing.
• Skimping on holdfasts / anchors — a frame on two screws works loose within a year.
• Hinges mortised too deep or too shallow — causes hinge-bind or a door that won't close.
• Gaps fitted too tight — fine in summer, binds in the monsoon; leave room and seal the edges.
• Wrong hand / swing — blocks a switch, a wall or another door; plan the swing first.
• Unsealed bottom and top edges — the door drinks moisture and swells; always seal end-grain.
• Strike plate misaligned — the latch won't catch; mark it from the closed leaf, not by guesswork.

Frequently asked questions

How long does it take to install one door?

A practised carpenter fits a leaf and hardware into an existing frame in roughly an hour. A full install — fixing the frame plumb into masonry, then hanging the leaf and hardware — is more like 2 to 4 hours per door, longer for heavy teak or steel doors.

Why does my new door bind only in the monsoon?

It was fitted with gaps too tight for the humid season. Timber and flush doors swell when they absorb moisture. The fix is to plane a little off the binding edge and then seal that edge so it stops drinking water — see door seals and weatherstripping.

Two hinges or three?

Three for any normal Indian door — top, middle and bottom. Two hinges let the leaf sag over time, especially on solid or teak doors. Heavy main doors sometimes get four. More on this in the door hinges guide.

Can I install a door myself?

Fitting a lock, handle or stopper to a door that already hangs well is a fair weekend job with a level, drill and sharp chisels. Setting a new frame plumb and square into masonry is genuinely skilled work — hire a carpenter for that, and always for heavy, fire-rated or security doors.

Where should the lock and hinges sit on the leaf?

Lock at about 900-1000 mm from the floor (comfortable hand height). Top hinge about 180 mm from the top, bottom hinge about 220 mm from the floor, third hinge roughly centred or slightly high where the load is greatest.
