An Insurance Deadline and Three Doors With Only Knobs

Deadbolt jobs sometimes come with a due date. Here's a typical example from a house north of the freeway.

A couple had just switched homeowner's insurance on their 1970s brick house a few streets north of Memorial City. The new policy came with a condition: deadbolts on every exterior door, with photos sent to the insurer by the end of the week. Otherwise, the coverage would change. The front door had a deadbolt. The back door, the side door to the yard and the door from the garage had only knobs. It was Wednesday.

The husband called us that morning. The dispatcher asked what each door was made of and whether any had glass near the lock. Back door: solid wood. Garage entry: steel. Side door: wood, with a narrow glass panel beside the knob. She booked the next morning. The technician would call when he was on the way.

The technician arrived on time, in uniform and showed his ID. He checked the husband's license against a tax notice. Then he went door by door. Back door first. He bored the face and edge holes with a jig at the right backset, chiseled the faceplate pocket, cut the strike mortise and set a heavy strike with 3-inch screws into the stud. The bolt threw a full inch without a push. Garage entry next. Steel doors take different bits and more patience. He drilled slowly to avoid tearing the skin, fitted the deadbolt and reinforced the strike side.

The side door was the one with the glass panel. The husband asked about a double cylinder deadbolt, so nobody could break the glass and reach in. The technician was direct: it's a fire risk if you can't find the key in smoke, and many fire safety guidelines advise against it in homes. He installed a single-cylinder deadbolt and suggested security film on the glass instead.

He keyed all three to the front door with his pinning kit and tested every lock from both sides with the doors closed. Then he stood back while the husband took photos of each door for the insurer. The photos went out that afternoon, with two days to spare. His advice: if you're changing insurance, read the security conditions before the policy starts, not after.

What Goes Into a Proper Deadbolt

Knob-Only Doors

To add deadbolt to door hardware that's only a knob, we bore the face and edge holes with a jig, set the faceplate flush, cut the strike mortise and test with the door closed. The bolt must throw its full inch without pushing on the door. If it doesn't, the strike is wrong.

Reinforced Strike Plate

The strike is where most forced doors fail. A heavy strike with 3-inch screws into the stud spreads the force into the framing. Short screws into a thin jamb are the weak point on most older doors around Memorial City.

Grade 1 or Grade 2

Grade 1 is the strongest residential rating. Grade 2 is solid for most homes. Look for a full one-inch throw and a hardened insert in the bolt. Skip the decorative bargain models with a short throw; they look fine and fail early.

Single or Double Cylinder

A double cylinder deadbolt needs a key on both sides. It stops someone reaching through glass, but it can trap you in a fire if the key isn't in the lock. Many fire safety guidelines discourage them in homes. Security film or a different door is usually the better answer.

The Garage Entry

The door from the garage into the house is often knob-only. That's the door a stolen garage remote leads to.

Steel and Fiberglass Doors

Steel and fiberglass doors need different bits and slower drilling. Done right, they hold a deadbolt well. Done badly, the skin tears or the core crushes. On steel doors with a thin edge, we add a reinforcer around the bolt so the door itself doesn't flex when the bolt is pushed.

Deadbolt Replacement Memorial City Homes Need

Worn, wobbly or low-grade deadbolts can be replaced in the existing holes in most cases. We upgrade the strike at the same time, because a new bolt in an old strike is still weak.

One Ring, Same Key

New deadbolts can be keyed to your existing key, so the ring doesn't grow. If your current keys are mixed brands, we can sort that out at the same visit. For the rest of the house, see rekey service.

Insurance and Rental Requirements

Some insurers and many leases require deadbolts on every exterior door. We can install them on a deadline and you can photograph each one for your records. Tell the dispatcher the date, and we'll book around it. If your insurer wants a written note listing the hardware installed, ask the technician for one.

Who Can Book

Owners, or tenants with landlord approval. We check ID against the address.

Keep the Bolt Working

Houston humidity is hard on locks. Once a year, spray a little dry lubricant into the cylinder and check that the bolt still throws without a push. If it starts to drag, the door has moved. Adjust the strike before the lock wears out.

Meeting You at the Spot in Memorial City

We reach customers across Memorial City with mobile technicians, not a storefront. Most installs are planned. Around Memorial City, the Gessner and Bunker Hill feeders are slow at rush hour. Mornings and early afternoons are best for planned work.

Straightforward Technicians

A uniformed technician with company ID does the work. They tell you what the door needs, what it doesn't, and why. They use jigs, sharp bits and long screws, test every bolt with the door closed, and clean up before leaving. If a door is too damaged or too thin to hold a deadbolt properly, they'll tell you before drilling.

Deadbolt Installation Around Memorial City

Around Memorial City, deadbolt work comes from older brick houses north of I-10 with knob-only side and back doors, newer townhomes where the garage entry has only a knob, rental properties that need deadbolts to meet a lease or insurance condition, and offices adding a deadbolt to a storage room. Deadbolt installation in Memorial City is usually a short visit per door. If you're searching to install deadbolt near me, start by counting the doors that have only a knob. In our experience, most houses around here have at least one, usually the side door to the yard or the door from the garage.

A good deadbolt needs a good door and frame. Before fitting, we check that the door sits square, the hinges are tight and the strike has solid wood behind it.

Choose the grade that suits the door. Basic, standard and heavy-duty bolts differ in how they resist force, and we explain the options.

Long screws in the strike do most of the work in a forced entry. We use ones that reach the stud.

If you like, we'll key the new bolt to match your handle set, so one key opens both.

Think about the back door too. People spend on the front and forget the rear, which is where many forced entries happen.

Ask about a security plate around the lock edge. It's a thin steel cover that stiffens the door where kicks usually land, and it does not change how the door looks much.

We also install deadbolts in Memorial, Spring Branch and Hedwig Village. For full new hardware, see lock installation.
