Exterior & Entry Door Installation in Los Angeles demands more than hanging a door and calling it done. In Los Angeles, where canyon winds test weatherproofing, year-round sun exposure fades and warps wood, and termite pressure is relentless, an entry door is a structural envelope component. Spanish Colonial Revival homes in Hancock Park, mid-century moderns in Silver Lake, and Craftsman bungalows across Los Feliz all need doors that seal tight, flash correctly, and resist the rot and insect damage that thrive in our Mediterranean climate. We install new doors weather-tight and properly sealed, repair rotted or termite-damaged frames and thresholds, and replace full units when repair isn't honest. The same carpenters who handle our structural work finish your door installation, which means your entry or back door gets the same rigor as a floor joist replacement.
Why Exterior & Entry Door Installation Matters in Los Angeles
Los Angeles doors face three constant threats: sun exposure that bakes and splits wood, wind pressure from canyon systems and coastal flows that stress frames and seals, and year-round termite activity that eats door jambs and thresholds from the inside out. A door installed poorly or left to rot becomes a pest entry point, a thermal leak, and a security weak point. The difference between a door that lasts 15 years and one that lasts 30 is flashing, sealant, proper frame repair, and wood species choice.
- We repair rotted door jambs and sills instead of replacing the entire unit when the wood justifies repair.
- We flash and seal exterior doors to stop water intrusion and wind-driven rain, a critical detail in Los Angeles canyon properties.
- We replace termite-damaged thresholds and frames using specifications from your own pest inspection report.
- We install doors square, plumb, and weather-tight, with proper clearance and hardware function verified before we leave.
- We work with your choice of wood species, fiberglass, or composite doors, installed to manufacturer spec and local building practice.
A properly installed and sealed door stops energy loss, keeps pests out, and protects your home's structural integrity for decades.
Key info: Termite damage to door frames is common in Los Angeles year-round. We work from your pest inspector's report, repair or replace the damaged wood, and install the door to standards that resist future intrusion. We do not treat or fumigate; that is a separate licensed trade.
For context on local building codes and permit requirements for door installation, refer to the Los Angeles Department of Building and Safety website, which publishes standards for residential openings and weather-tight installation.
How We Install and Repair Exterior & Entry Doors in Los Angeles
Door installation begins with an honest assessment of the existing frame. If the jamb, sill, or threshold shows rot or termite damage, we remove the damaged wood, replace it with pressure-treated or rot-resistant species, and flash the opening before hanging the door. If the frame is sound, we remove the old door, prep the opening, set the new unit plumb and square, shim it tight, seal it, and install hardware. Every exterior door gets flashed at the sill and head to shed water and block air infiltration. We test the door swing, latch function, and weather seal before finishing.
- We inspect the door opening and existing frame for rot, termite damage, or structural movement.
- We remove and replace damaged jambs or sills with pressure-treated lumber or rot-resistant species.
- We set the new door unit plumb, square, and level, shimming and fastening per manufacturer specification.
- We flash the sill and head with metal or membrane to shed water and stop air leakage.
- We seal the frame perimeter with polyurethane or acrylic caulk rated for exterior use and UV exposure.
- We install hardware, test the latch and swing, and verify weatherstripping compression.
The result is a door that operates smoothly, closes tight, and sheds water and wind for years to come.
Local example: A Craftsman home in Highland Park had a rotted entry door sill and termite-damaged jamb. Rather than replace the entire unit, we removed the damaged wood, sistered in new pressure-treated framing, flashed the opening, and hung a new solid-core exterior door. The homeowner kept the original casing and hardware, and the repair cost far less than a full-frame replacement. The door now sheds water properly and resists future termite entry.

Methods and Materials for Exterior & Entry Door Installation
| Approach | Description | Best for |
|---|---|---|
| Frame Repair and Replacement | Remove rotted or termite-damaged jambs and sills, replace with pressure-treated or rot-resistant lumber, and reinstall the existing door or hang a new one. | Doors with sound hardware and casing but damaged frames; cost-effective when the opening itself is structurally sound. |
| Full Unit Installation | Remove the entire door assembly and frame, prep the opening, and install a new pre-hung door unit with flashing and sealant. | New construction, major remodels, or when the existing frame is beyond repair or the opening needs resizing. |
| Flashing and Sealing | Install metal or membrane flashing at the sill and head, and seal the frame perimeter with exterior-grade polyurethane or acrylic caulk. | All exterior doors; prevents water intrusion and air leakage, critical in Los Angeles canyon wind and sun exposure. |
| Wood Species Selection | Choose from solid wood (Douglas fir, redwood), fiberglass, or composite doors based on durability, aesthetics, and budget. | Heritage or period homes where wood is expected; modern homes where low-maintenance fiberglass or composite suits the style. |
Exterior & Entry Door Installation Cost in Los Angeles: What to Expect
Door installation in Los Angeles starts at around $850 for a standard single-entry door replacement with a sound frame and no rot repair. The cost rises based on frame damage, wood species, door material, hardware selection, and whether flashing or sealant upgrades are needed. A door with a rotted sill or termite-damaged jamb that requires frame repair can run $1,200 to $2,000 or more, depending on the extent of the wood replacement. French doors, double units, or specialty doors (fiberglass, solid-core, insulated) also push the price higher. Travel is included in our Los Angeles service area, and we provide a free estimate within 24 hours at (213) 652-2684.
The best approach is to get 2 or 3 estimates and understand what each includes: frame repair or replacement, flashing, sealant, hardware, and labor. A detailed estimate also clarifies whether permits are needed for your specific opening or HOA rules. See our full pricing overview for more context on how we price residential carpentry work.
Factors that affect cost include the size and condition of the existing frame, the material and style of the new door, the complexity of flashing and sealing, and the accessibility of the opening. A back door in a canyon property exposed to wind may need more robust flashing than a front entry in a sheltered location. Get the estimate in writing and ask what happens if we discover additional rot or damage once we open the wall.
What to Look for When Hiring a Carpentry Contractor Near Los Angeles for Door Installation
Choose a contractor who has done residential door installation in Los Angeles and understands local wind, sun, and termite pressures. Ask to see examples of recent work, and call references who had doors installed within the last 2 or 3 years. Confirm that the contractor is fully insured and can document coverage. Get multiple estimates in writing, and compare what each one includes: frame repair, flashing, sealant, hardware, and cleanup. Ask whether permits are required for your specific opening; some jurisdictions require a permit for exterior door replacement, others do not. Check any HOA rules or architectural guidelines if your home is part of a managed community.
The right contractor explains the repair versus replacement decision honestly. If your frame has sound wood and good casing, repair is cheaper and preserves character. If the frame is deeply rotted or structurally compromised, replacement is the right call. A contractor who pushes replacement without showing you the damage, or who minimizes the importance of flashing and sealing, is not thinking long-term about your home's durability.
