Service coverage includes Wilmington Manor, Newark, Christiana, Minquadale, and New Castle as neighboring towns where we also work. When you call from a Wilmington ZIP we confirm details specific to local door styles and common jamb conditions. Our technician carries a range of deadbolts and replacement hardware suited to houses and duplexes in New Castle County. If a special part is required we will explain options and the next steps before starting. All work follows local building and safety norms applicable in Wilmington.
A proper deadbolt installation starts with confirming whether the door already has a bored hole sized for a deadbolt or if a new hole must be drilled. Many exterior doors accept a standard 2-1/8 inch bore, but some older or composite doors require different fittings or reinforcement. We inspect the strike plate and jamb; a secure deadbolt needs a reinforced jamb and a properly aligned strike to work reliably. If the existing door edge is too thin or the bolt doesn’t engage fully, options include a longer strike, a reinforcement plate, or a different bolt length to match your door’s thickness. Cylinder type matters: single-cylinder deadbolts are keyed on the outside and thumbturn inside, while double-cylinder models require a key on both sides; we explain pros and cons so you can choose. Weather, door material, and frame condition can affect what we install, and we recommend hardware that balances security and everyday convenience. After installation we test several cycles of the bolt and show you how to use and maintain the lock, including lubrication and key care to reduce future wear.
What affects the cost
Cost depends on what the door needs and the deadbolt model you choose, not on travel or time of day. We give a clear phone quote before any work begins so you can decide without surprises.
- Type of deadbolt
- Condition of door jamb
- Need for new bore
- Reinforcement hardware
- Special cylinder or keying
Worth knowing before you call
A common misconception is that all deadbolts and doors are the same; they are not. Door thickness, material, and pre-existing holes change what will fit and whether reinforcement is needed. Choosing the cheapest cylinder without checking the keyway or security rating can leave you with poor durability and greater vulnerability. Double-cylinder deadbolts (key on both sides) are sometimes chosen for security but can create an egress hazard in an emergency; consider that trade-off before ordering. If your jamb or frame shows rot, installing a new deadbolt without addressing the frame weakens the result; reinforcement plates or repair should be part of the plan. Keep a spare key in a safe place and consider getting extra keys cut at the time of installation to avoid needing a second visit. Finally, routine lubrication with the right products keeps the bolt working smoothly and reduces the chance of key or cylinder problems later.
Before we arrive
Preparing a few simple things before the visit speeds the assessment and helps the technician start work right away. If possible, gather information about the door and any existing lock.
- Have the door key or note if keys are missing
- Measure or note door thickness if known
- Clear furniture from the door swing area
- Unlock and open the door for inspection

Questions from Wilmington customers
These are the questions people ask most before booking this service. If your Wilmington question isn't here, call us — we'll answer it directly.
Do you install deadbolts in Wilmington homes?
Yes, we install deadbolts for residences in Wilmington, DE. When you call we ask about the door type and zip code to confirm parts and availability. A phone quote is given before we start any work.
Can you install a deadbolt on an older Wilmington door?
Older doors in Wilmington can usually accept a deadbolt but they sometimes need additional reinforcement or a different bore size. We inspect the door and jamb to recommend the right hardware and any reinforcement. If a special part is required we explain your options on site.
Should I choose a single-cylinder or double-cylinder deadbolt in Wilmington?
Single-cylinder deadbolts have a thumbturn inside and a key outside; they are convenient for everyday use in Wilmington households. Double-cylinder models require a key on both sides, which may increase security but can delay escape in an emergency. We will discuss the trade-offs during the phone consultation and again at the home so you can choose what fits your needs.
Will the deadbolt fit my door without drilling new holes in Wilmington?
That depends on your door’s existing bore and the type of deadbolt you choose; some doors already have the standard hole while others will need new drilling or minor routing. The technician inspects the door and explains whether new holes are required before any work begins. You’ll receive a verbal quote for the confirmed scope at that time.
How secure is a newly installed deadbolt in my house?
A correctly installed deadbolt significantly improves security compared with a simple latch. Security also depends on the quality of the cylinder, the strike plate, and the condition of the door frame. We recommend reinforcement if the jamb shows wear or if you want higher resistance to forced entry.
