Secure Your Entries and Improve Your Curb Appeal

Door installation and replacement in Lancaster for interior and exterior doors that fit correctly and perform for years.

Your home in Lancaster may have an entry door that sticks in the frame, lets light through the edges, or shows wear from sun exposure and daily use. Interior doors may not latch properly, hang crooked, or lack the style you want after a remodel. Door installation and replacement solves these issues by removing the old unit, preparing the rough opening, and installing a door that closes smoothly, seals against weather, and matches your hardware and trim. First Choice General Contractor handles both interior and exterior doors, and the crew ensures the frame is square, the hinges are mortised correctly, and the threshold or sweep blocks drafts.

Exterior doors in Lancaster need to resist heat, block wind, and stand up to temperature swings that stress the materials. Steel and fiberglass doors offer durability and insulation, while wood doors provide traditional appearance and can be stained or painted. Interior doors are typically hollow-core or solid-core, and you choose between panel, flush, or glass designs depending on the room. The installation includes shimming the frame, securing it to the studs, and sealing gaps with low-expansion foam. This service works well when paired with window replacement or stucco repair, especially if you are updating the exterior appearance of an older Antelope Valley home.

How the frame gets leveled and the door gets sealed

The crew in Lancaster removes the old door and frame, checks the rough opening for damage or rot, then installs the new frame using shims and a level to ensure it sits plumb and square. Exterior doors are sealed with weather stripping, caulking, and a threshold that sits flush with the floor. Interior doors are hung on three hinges, and the latch plate is mortised into the jamb so the door closes without rubbing. Locksets and deadbolts are installed according to the manufacturer's template, and the strike plate is positioned so the bolt engages fully.

After installation, the door will open and close without resistance, the lock will engage smoothly, and you will not feel air movement around the edges when the door is shut. Exterior doors will block light from showing through the frame, and interior doors will stay in the position you leave them without swinging open or closed on their own.

This service includes disposal of the old door and frame, but it does not include painting or staining unless specified in the estimate. If the rough opening is out of square or damaged, the crew will rebuild the framing before the new door is installed. The work pairs well with trim upgrades, flooring installation, or remodeling projects that change the layout of doorways.

These are the questions that come up during estimates

The details below help you understand what is included in the installation and what decisions you will need to make before the work starts.

What is the difference between pre-hung and slab doors?
Pre-hung doors come with the frame, hinges, and jamb already assembled, which makes installation faster and ensures the door fits correctly. Slab doors are just the door panel and require the frame, hinges, and hardware to be installed separately.
How long does door installation take?
A single interior door typically takes two to three hours to remove, install, and adjust. Exterior doors take longer due to sealing, threshold installation, and lockset alignment, and usually finish in four to five hours.
What material is best for exterior doors in Lancaster?
Fiberglass and steel doors perform well in Lancaster because they resist warping, do not require frequent repainting, and provide better insulation than wood. Wood doors offer a traditional look but need regular maintenance to prevent cracking and fading.
When should I replace a door instead of adjusting it?
You should replace a door if the frame is warped, the door is cracked or damaged, or if gaps around the edges cannot be closed with weatherstripping. First Choice General Contractor inspects the frame and hardware to confirm whether replacement is necessary.
Why does a door need to be shimmed during installation?
Shims fill the gap between the door frame and the rough opening, allowing the crew to level and square the frame before fastening it to the studs. Without shims, the door will bind, not latch correctly, or leave uneven gaps around the edges.
