Lock change in Georgetown, DC
Georgetown has the oldest housing stock in Washington, and it changes the job completely. Federal and Victorian rowhouses along N Street, O Street, and Wisconsin Avenue frequently still carry their original doors — solid wood, often with mortise locks, sometimes with hardware that has been in place for a hundred years and looks it.
That means a lock change here is rarely a matter of unscrewing one unit and screwing in another. Done carelessly it damages a door that cannot be replaced. Done properly, you get modern security behind period hardware that still looks right.
When should you change your locks?
- You just bought or moved into a Georgetown property — you have no idea how many keys the previous owner handed out
- Keys are missing or you suspect copies exist
- A tenant, contractor, cleaner, or short-term guest had access
- The lock sticks, feels loose, or no longer throws cleanly
- You want a genuine security upgrade rather than the builder-grade hardware you inherited
- After a break-in or attempted entry
Change the lock, or just rekey it?
This is the question worth answering before spending anything, and the honest answer often saves people money.
Rekey if the hardware is sound and your goal is that old keys stop working. We repin the existing cylinder to a new key — + per lock, and multiple doors can be keyed alike so one key opens them all. On a Georgetown house with attractive original hardware, this is very often the right call: you keep the door exactly as it is.
Replace if the lock is worn out, damaged, missing parts, or if you want a security level the existing hardware cannot provide — a Grade 1 deadbolt, or a high-security cylinder with key control.
Working with Georgetown’s historic doors
A few realities specific to the neighborhood:
Mortise locks are common. These are rectangular lock bodies set into a pocket cut in the door edge — an entirely different mechanism from the bored cylindrical locks sold at hardware stores. There is no drop-in modern equivalent. What there is, and what we usually recommend, is a cylinder retrofit: keeping the original mortise case and escutcheon while fitting a modern, higher-security cylinder inside it. The door looks untouched; the security is current.
Georgetown is a historic district. Changes to the visible exterior of contributing properties can fall under review. Retrofitting inside existing hardware sidesteps that concern entirely, which is another argument for it over wholesale replacement.
Old doors move. A century of DC humidity means the door and frame are not the shape they started as. Before we change anything we check the alignment between bolt and strike — frequently the “failing lock” is a strike plate that needs adjusting, and a $75 fix beats a $400 one.
What we install
- Deadbolts — the highest-value upgrade on any front door, fitted with a reinforced strike and 3-inch screws into the framing
- Knob and lever sets — matched to the door’s period where appearance matters
- Mortise cylinders — including high-security retrofits into original cases
- High-security locks — Medeco, Mul-T-Lock, ASSA ABLOY, with restricted keys that cannot be copied without your authorization
- Smart and keypad locks — where the door prep allows; useful for rental and guest properties
- Keyed-alike sets — front, back, basement, and garden gate on a single key
Frequently asked questions
Is it cheaper to rekey or change a lock in Georgetown?
Rekeying is cheaper — + per lock versus new hardware plus installation. If the existing lock is in good condition and you simply want old keys invalidated, rekeying achieves exactly that.
Can you replace a lock without damaging my historic door?
Yes, and in most cases we retrofit rather than replace — fitting a modern cylinder into the original mortise case so the door’s appearance is preserved. Full replacement is a last resort on a period door.
Do I need approval to change locks on a Georgetown home?
Interior mechanism changes and cylinder retrofits are not generally an issue. Changes that alter the visible exterior appearance of a contributing historic property may fall under review — another reason retrofitting is usually the cleaner path. Check with your own property’s requirements if in doubt.
Can all my doors use the same key?
Yes. Keying alike across front, back, basement, and gate is standard and makes life considerably simpler on a multi-entrance rowhouse.
My lock is stiff — does it need replacing?
Often not. Stiffness in a Georgetown door is usually seasonal swelling pushing the bolt out of alignment, or a cylinder that needs cleaning and dry lubricant. We check that before recommending anything.
