Across Denver and the Front Range

Professional Door Installation and Lock Services

Interior doors, exterior entries, smart locks, and weathersealing from contractors who know how doors work in Colorado's climate. .


A door is security, insulation, and the first impression of your home. When a door sticks, a lock is unreliable, or you need a new entry, you want a contractor who understands proper fitting, weathersealing, and the specific challenges of Denver's altitude and temperature extremes. The Handyman Services installs interior doors, exterior entries, storm doors, and smart locks for homeowners across Denver, Westminster, Lakewood, Aurora, and the Front Range. We do prehung and slab door installation, secure deadbolts and smart locks, fix warped frames, and seal doors properly so they close smoothly and keep cold air out. We're not just hanging a door. We're making sure it works reliably and securely for years.

Interior Door Installation

Whether you're replacing an old hollow-core door or installing new doors during a remodel, we handle interior door installation. Prehung doors come in a frame—we set them plumb, shim them level, and secure the frame to the studs. Slab doors are single panels—we build or fit a frame and hang the door so it swings smoothly without rubbing or binding. We install solid-core doors for bedrooms and bathrooms, bi-fold closet doors, pocket doors for tight spaces, and barn-style sliding doors for rustic or modern looks. We ensure doors close smoothly, latches catch reliably, and hinges don't sag.

Exterior Door Installation: Entry and Patio Doors

Your front door is security and weather defense. We install entry doors (single, double, or French), patio sliding doors, and glass doors. Proper installation means a tight seal against weather, correct hardware security, and smooth operation. Denver's temperature swings—90 degrees in summer, 20 below in winter—cause wood and metal to expand and contract. We account for this. We install doors with proper weatherstripping, install flashing correctly so water doesn't get behind the frame, and ensure the threshold and sill drain water away. A door installed right keeps your home warm in winter and cool in summer.

Storm Doors and Secondary Entry Protection

Storm doors add an insulating air gap, reduce heating and cooling loss, and protect your main entry from weather. We install aluminum or wood storm doors, ensure they're plumb and secure, and verify the closer works smoothly so the door doesn't slam. A storm door also extends the life of your main door by shielding it from harsh weather. In Colorado, this matters.

Door Lock and Deadbolt Installation

A flimsy lock or a worn-out latch isn't security. We install heavy-duty deadbolts, modern passage locks, and interior privacy locks. We bore holes to spec, mortise strikes correctly, and test the lock mechanism so it operates smoothly and holds securely. If you need to replace existing locks—because you've lost a key, inherited a home, or want better security—we install new locks without damaging the door or frame. We also adjust latch bolts that don't catch or doors that don't latch properly.

Smart Lock Installation

Smart locks—keypad entry, smartphone apps, fingerprint, or traditional key—are becoming standard. We install them correctly so they work reliably. This means a solid wood door (not hollow-core, which can't support the weight), proper wiring if hardwired, and integration with your existing smart home system if needed. We handle Yale, Level Lock, Schlage, and other major brands. We also advise on backup power so you're not locked out if the battery dies.

Door Frame Repair and Replacement

A stuck door often isn't the door—it's the frame. Settling, water damage, and temperature swings cause frames to warp. We repair cracked or warped frames by shimming and adjusting, and if the frame is beyond repair, we replace it. We also repair strike plates, door jambs that are damaged or rotted, and thresholds that have deteriorated. Fixing the frame often solves the sticking door problem without replacing the door.

Weathersealing and Energy Efficiency

A door that leaks cold air in winter is expensive. We install or replace weatherstripping (door sweeps, side seals, head seals) to create an air-tight seal. We also install proper thresholds and door frames with thermal breaks if you're doing an exterior replacement. In Denver, where winters are cold and altitude is high, proper weathersealing can reduce heating loss significantly. We make sure your door doesn't become a heat leak.

Security and Confidence

We install heavy-duty locks and deadbolts rated for residential security. We mortise them correctly and test them thoroughly. If you're adding a smart lock, we verify it integrates properly with your system. You'll know your doors are secure.

WHY US

Denver Climate and Altitude Expertise

Licensed, Bonded, Insured

We know what Colorado does to doors. Temperature swings cause wood and metal to expand and contract. Altitude and dry air affect sealing and operation. We install doors with these challenges in mind. Weatherstripping choices, frame material, and installation technique all account for Front Range conditions.

Attention to Weather and Details

Exterior door installation isn’t just hanging the door. It’s flashing, threshold slope, weatherstripping, and making sure water doesn’t get behind the frame or into your wall. We install doors so they keep weather out and heating/cooling in.

Frequently Asked Questions

What Most People Ask Us

A prehung door comes already hung in its frame—you install the whole assembly into the opening. It's faster and usually more reliable. A slab is just the door panel. You either use an existing frame (cheaper) or build/install a new frame (more work). Prehung is standard unless you have a custom frame or special situation.

Not usually. Most doors that stick or won't latch are suffering from frame issues, hinge problems, or swelling due to humidity. We diagnose and adjust. We may sand or trim the door if it's swollen, or repair the frame. New door is the last resort.

A single interior door: 1-2 hours. An exterior entry door: 2-4 hours depending on frame condition and weathersealing required. Multiple doors or frame repair can take longer. We give you a timeline when we quote the job.

Solid wood is classic and beautiful but requires maintenance (stain/paint). Fiberglass is low-maintenance and energy-efficient, resists warping from temperature changes, and is popular in Colorado. Steel is secure and durable. The choice depends on your home's style and maintenance preference. We advise based on your specific door and climate exposure.

Yes, if the door is solid (wood or solid composite) and in good condition. Hollow-core interior doors can't support the weight of most smart locks. We verify door condition and recommend a replacement if needed. Smart locks also need reliable power, so we discuss battery backup or hardwiring options.

Not necessarily. Slight warping can be corrected by shimming and adjusting hinges. More severe damage (rot, deep cracks, major twisting) may require frame replacement. We assess the damage and recommend the most cost-effective fix. Bad concrete fails even with seal. Good concrete stays durable when sealed.

If you feel drafts around the door, see gaps between the door and frame, or the door is hard to open/close, weatherstripping is likely worn. We inspect and replace as needed. Weatherstripping is inexpensive and pays for itself through reduced heating/cooling loss.

Yes. We coordinate with your contractor on timing. Doors usually go in after framing and before trim/painting. We can also install doors in walls that are already finished, though it's messier. We plan the work to minimize disruption.

Yes. We install commercial-grade locks, closers, and exit hardware. We're familiar with ADA requirements and can advise on compliance. Contact us to discuss your commercial project.
