Door Frame Repair and Jamb Replacement in Toronto

The frame is the part of a door assembly that fails quietly. People replace slabs, change locks and adjust hinges for years without realising the jamb underneath has rotted, split or dropped out of square — which is why the new door still sticks. Door Repair Near Me repairs and replaces door frames and jambs across Toronto and the GTA, for homes, storefronts and commercial buildings. Call (647) 955-5637 for a free estimate.

Frame Problems We Fix

• Rotted jamb bottoms — the most common exterior frame failure in Ontario, caused by water sitting at the sill
• Split jambs after a forced entry — see break-in damage repair
• Frames pushed out of square by structural settling
• Loose or pulled hinge jambs where screws no longer bite
• Damaged strike sides where the latch has torn out of the wood
• Rusted or bent hollow metal frames in commercial and industrial buildings
• Exterior brickmould and casing rot around the frame perimeter

How to Tell the Frame Is the Problem

Before assuming a door needs replacing, these signs point at the frame instead:

• The gap around the door is uneven. Wider at the top on one side than the other means the frame has racked. A new slab will bind exactly the same way.
• The latch misses the strike. If the door has to be lifted or pushed to lock, the frame has usually dropped.
• The jamb is soft. Press a screwdriver into the jamb bottom near the sill — if it sinks, that is rot, and paint has been hiding it.
• Hinge screws keep loosening. The hinge jamb has lost its grip and needs solid backing, not longer screws.
• Daylight along the stop. An even door against an uneven frame shows as a wedge of light.

Repair or Replace the Frame?

Frames are worth repairing far more often than people assume, because a section can be replaced without disturbing the surrounding wall, trim or brickwork.

Section repair suits localised damage — a rotted 300 mm at the jamb bottom, a split at the strike, a hinge area that has lost its bite. We cut out the damaged section, splice in matched material, reinforce behind the hardware and refinish. It is faster, cheaper and leaves the exterior finish intact.

Full frame replacement is the honest answer when rot has travelled up the jamb, the frame is racked beyond shimming, or a hollow metal frame has corroded through. In that case a pre-hung unit is often the better value — see door replacement.

Why Frame Rot Keeps Coming Back

Repairs that only address the visible rot fail again within a few seasons, because the cause is almost always water management rather than the wood itself. When we repair an exterior frame we also deal with the source: sill slope and drainage, a failed or missing door sweep, caulking that has separated at the brickmould, and cladding the exposed jamb bottom where the sill design keeps trapping water. Fixing the wood without fixing the water is why so many frames get repaired twice.

Commercial and Hollow Metal Frames

Commercial frames fail differently — corrosion at the base in wet or salted entrances, distortion from impact, and anchors working loose in masonry. On hollow metal we can repair base corrosion, reweld and reinforce hinge and strike areas, straighten distortion where the section is sound, and reanchor frames that have loosened. On fire-rated assemblies, any frame work has to preserve the rating, so the repair must keep the labelled assembly intact. See commercial door repair.

Frequently Asked Questions

Can a door frame be repaired without replacing the whole thing?

Usually yes. Localised rot, splits and worn hinge or strike areas can be cut out and spliced with matched material, which avoids disturbing the trim and exterior finish.

My door sticks — is it the door or the frame?

If the gap around the door is uneven, or the latch misses the strike, it is almost always the frame. A new door in a racked frame will stick the same way.

Can you repair a frame after a break-in?

Yes. Split jambs and torn strike areas are repaired and reinforced, usually with a solid backing and long screws into the stud so the same kick does not succeed twice.

Do you repair metal commercial frames?

Yes — base corrosion, impact distortion, loose anchors and worn hinge and strike areas on hollow metal frames.

Exterior Door Jamb Replacement

Sometimes only one side of the frame has failed. The hinge jamb is solid, the head is fine, but the latch jamb has split along the deadbolt or rotted at the bottom. In that case there is no need to replace the whole frame. We remove the casing on both sides, cut out the damaged jamb, and install a new one matched to the existing depth and stop profile.

The details that make a jamb replacement last:

• Prime every cut end before installation, especially the bottom end grain where water soaks in.
• Shim behind the strike and deadbolt so the screws pull against solid framing, not an air gap.
• Use a long reinforced strike with screws that reach the wall stud. This is what stops a kick from splitting the new jamb the same way.
• Seal the joint at the sill so meltwater cannot wick up into the new wood.

On older Toronto houses, jamb depths and stop profiles are often not standard sizes, so we mill or build up the new jamb to match rather than forcing a stock piece into place.

Broken Door Frame Repair

A broken frame is different from a worn or rotted one. Something has hit it or forced it: a break-in, a moving truck, a door caught by wind and swung into the wall. The damage is sudden, often splintered, and the door may not close at all.

What we check first

• Is the break limited to the jamb, or has the frame been pushed away from the wall framing?
• Are the hinges still attached to solid wood, or have the screws torn out?
• Is the slab itself bent, cracked or delaminated?

If only the jamb is broken, a splice or jamb replacement restores it. If the frame has moved in the wall, it needs to be reset and re-anchored, which is a bigger job but still usually cheaper than a new door. After a forced entry, our door break-in repair service covers securing the opening and the repair that follows.

Door and Door Frame Replacement Together

When both the slab and the frame are worn out, replacing them as one unit is usually the better spend. A pre-hung door comes with the slab already hung in its own frame, with a matched sill and weatherstripping. Everything is square to everything else from the factory, which is hard to achieve when fitting a new slab into an old, twisted frame.

Pre-hung unit vs slab only

A slab-only replacement keeps your existing frame and hangs a new door in it. It makes sense when the frame is solid, square and dry, and you only need a new door for looks, security or because the old slab is damaged. The catch is that the new slab must be mortised for hinges and bored for the lock to match the old frame exactly.

A pre-hung unit is better when:

• The sill is cracked, sagging or rotted.
• The jambs are soft at the bottom on both sides.
• The opening is out of square and the old door has been planed several times to make it close.
• You are changing the door style, size or adding sidelites.

Our published starting prices for a full replacement are a front entry door from $999, a steel entrance door with glass insert from $1,199, and a fiberglass door with glass insert and design from $1,499, with free in-home measurement.

Garage Service Door Frame Repair

The small door into the garage, sometimes called a man-door or service door, is one of the most neglected doors in a house. It often sits at ground level with no overhang, takes snow and rain directly, and frequently has a wood frame on a concrete floor with no proper sill. The bottom of the frame rots first, then the hinge side lets go.

Repair is the same as on a front door: cut out the rot, splice or replace the jamb, and fit a proper sill or threshold so water stops sitting against the wood. Because this door is often an easy target for break-ins, it is worth reinforcing the strike and fitting a good deadbolt at the same time. If the large overhead door is the problem rather than the service door, see our garage door repair page.

More Door Frame Repair Questions

Does a new door frame always need a new sill?

No. If the sill is solid, level and draining properly, it can stay. If it is cracked, soft or sloping toward the house, it should be replaced with the frame, or the new jamb will rot from the bottom again.

Is it cheaper to replace the door and frame together?

Not cheaper than a frame repair, but often better value than a new slab plus several frame repairs. If both the door and the sill are worn, a pre-hung unit usually costs less over time.

Can a new slab fit in my old frame?

If the frame is square and sound, yes. The new slab is prepared to match your existing hinge and lock positions. If the frame is twisted, the new slab will bind just like the old one.

Why does my garage side door frame keep rotting?

Usually because there is no proper sill or the frame sits directly on concrete with no gap or seal. Water collects at the bottom of the jamb. Fixing the sill is as important as replacing the wood.
