Doors, Locks & Carpentry in Knightdale, NC

What the lock is actually attached to

Knightdale is largely new subdivisions, so the doors and hardware here mostly came out of one era of production building. The deadbolts are generally fine. What holds them is not.

Here is how a deadbolt works structurally. The bolt slides out of the door and into a hole in the door jamb — the vertical trim piece running up the side of the opening. Around that hole is a strike plate, which spreads the load.

The jamb is not structure. It is a relatively thin, soft piece of timber trim, fixed into the rough opening beside it. The actual framing — the studs that carry the house — is an inch or so further out, behind the jamb.

In a typical builder installation, the strike plate is fixed with short screws that bite into the jamb and go no further.

So the entire assembly relies on that strip of trim. Force applied to the door does not break the lock; it splits the jamb, and the strike plate comes away with a piece of trim attached.

The fix

Screws long enough to pass through the jamb, through the shim space behind it, and into the structural framing beyond.

Same plate. Same lock. Completely different fixing.

It takes ten minutes per door and costs the price of a handful of screws, and it is the highest-value security change available on almost any house of this type. It is also the one almost nobody has made, because it is invisible and nobody was ever told about it.

Do the hinges too. The hinge side of an exterior door is fixed the same short way, and it is the other place a door assembly gives. Long screws there while the door is already off its stops cost nothing extra.

Reinforced strike plates are available too — a longer plate covering more of the jamb, with several long screws. On a front door that is a worthwhile step up from the standard plate, and it is still a ten-minute job.

Check the bolt actually throws

Related, and worth two seconds of your time on every exterior door.

Turn the deadbolt with one finger, without touching the door. If it throws smoothly and fully, the alignment is good. If it needs the door pushed, pulled or lifted, or if it needs real force, the bolt is not fully entering the strike hole.

A partly engaged bolt is doing a fraction of the job it looks like it is doing.

The cause is nearly always that the door has dropped slightly, or that the strike was fitted a fraction out. Both are quick to correct: fixing the door position, or repositioning the strike so the bolt lines up. Filing the hole bigger is the shortcut and it makes the door rattle, so it is the last resort.

This also matters if you are thinking of a smart lock. Those have a small motor with limited torque — enough to throw a bolt that moves freely and not much more. Fit one to a misaligned deadbolt and it jams intermittently, eats batteries and gets blamed for a problem that was there before it arrived. Fix the alignment first.

The rest of the door work in new houses

Seasonal binding. Doors swell in summer humidity and shrink in winter. A door that sticks in August and behaves in January should not be planed — remove material now and you own a permanent gap in four months. The clearance gets recovered by fixing hinges and adjusting the strike.

Loose top hinges. The most common cause of a sticking door anywhere. The top hinge carries most of the door weight, its screws lose grip in the jamb, the door tips, and the top corner on the latch side binds. Longer screws into the framing behind lift it back to square — the same principle as the strike plate.

Hollow-core interior doors. Standard in these houses. They split at the hinge side where screws have pulled and fail at the lock block where a handle has been forced. Some of that is repairable and some is not, and we will say which rather than filling something that will fail again.

Builder handles. Hollow, light and increasingly rattly. Worth upgrading on the doors you use most — the front door and the door from the garage — rather than throughout.

The garage-to-house door. Where there is an attached garage, that opening is a rated assembly with a self-closer, not an ordinary interior door. If the closer has been removed or has lost its adjustment, refitting it is quick and worthwhile.

Sliding and patio doors. Usually rollers and track debris rather than anything structural.

Trim, baseboards and small carpentry

Profiles in these houses are current, so matching is straightforward. Common jobs are casing damage from furniture and vacuum cleaners, mitres that have opened as the house dried out, skirting that has come away from the wall because it was fixed into drywall rather than framing, and gaps at the floor after a flooring change.

On that last one: if you have had a floating floor laid, the gap along the skirting is deliberate — it is the expansion gap the floor needs. It gets covered with shoe moulding pinned to the baseboard, not filled and not nailed down through the floor.

Small carpentry, concretely: alcove and closet shelving, boxing in a pipe run, a window seat, replacing builder wire shelving with something that survives use, a stair spindle, trim around a new opening.

Not structural framing and not anything requiring a permit. Send a photo if you are unsure and we will tell you honestly.

Bundling, because of the drive

Knightdale is about forty minutes from us. There is no travel surcharge, and a single door adjustment at that distance is not good value for you.

Door and trim work batches well — the tools are out, the saw is set up, and the tenth item costs a fraction of the first. Walk the house once with a pencil.

Getting a price

Photograph the door closed with a close-up of the gap along the top and latch side. For hardware, a photo of the strike plate with the door open, and tell us whether the deadbolt throws easily with one finger.
