🚪 Interior Door Installation & Replacement
Interior door installation is one of the most technique-sensitive carpentry tasks in any home — an improperly hung door reveals itself immediately through uneven reveals, a door that swings on its own, or a latch that misses the strike plate by a fraction of an inch. FTL’s Union Master Carpenter background means every interior door is hung with consistent reveals, correct shim placement, and hardware positioned for years of trouble-free operation.
Interior door types we install:
Pre-Hung Interior Doors The most common interior door installation — a complete door unit with frame, hinges, and stop molding pre-assembled. We remove the existing door and frame, set the new pre-hung unit plumb and level in the rough opening, shim all three sides, fasten through the shims to the rough framing, install the casing on both sides, and set the latch hardware and strike plate for perfect operation.
Slab Door Installation Installing a new slab door (door panel only) into an existing frame — fitting the door to the opening by planing to correct clearance, routing new hinge locations or reusing existing mortises, drilling the latch bore, and hanging the door with correct reveal and operation.
Hollow-Core Doors The standard interior passage door for most South Central PA homes — lightweight, affordable, and available in a full range of profiles from flush to six-panel and two-panel designs.
Solid-Core Doors A significant upgrade from hollow-core — solid-core doors use a particleboard or composite core that adds meaningful weight, dramatically improves sound blocking between rooms, and provides a more substantial, higher-end feel to every doorway they’re installed in. Increasingly popular for primary bedrooms, home offices, and media rooms throughout Mechanicsburg and Harrisburg.
French Door Installation Double-door pairs with glass panels — the most dramatic interior door upgrade available. FTL installs French doors in existing openings and new openings, with proper header sizing for wider spans, astragal installation between panels, and full casing on both sides. Available in both swinging and sliding configurations.
Bifold Door Installation Folding door pairs for closets, laundry rooms, and pantries — properly tracked, aligned, and adjusted for smooth operation. FTL installs and adjusts bifold systems of all sizes.
Bypass (Sliding Closet) Door Installation Dual-panel sliding doors on overhead tracks — properly weighted and tracked for smooth side-to-side operation. FTL installs bypass systems in standard and custom widths for closets and storage spaces throughout South Central PA.
Pocket Door Installation Sliding doors that disappear into the wall cavity — eliminating door swing clearance requirements in tight spaces. FTL installs pocket door frames in both new construction and existing wall applications, with proper cavity framing, door fitting, and hardware installation.
Barn Door Installation Wall-mounted sliding doors on surface-mounted track hardware — the most popular interior door upgrade in South Central PA over the past decade. FTL installs barn door hardware and doors with proper wall blocking, level track mounting, and door weight capacity verification. Available in wood, MDF, mirror, and glass panel options.
🏠 Exterior Door Installation & Replacement
An exterior door is your home’s primary security element, its most significant curb appeal feature, and one of its most important energy-efficiency components. FTL installs exterior doors with the weathertight precision Pennsylvania winters demand:
Entry Door Installation Complete exterior entry door replacement — the most impactful single exterior upgrade available for most South Central PA homes. Our entry door installation includes:
- Existing door and frame removal — including any rotted threshold, sill pan, or door buck components
- Rough opening inspection — assessing framing condition, sill pan flashing, and any moisture damage before installation begins
- New door unit installation — pre-hung door set plumb, level, and square in the rough opening; shimmed at all hinge locations and latch side
- Threshold installation — new adjustable threshold properly sloped for weathertight sill seal
- Exterior flashing — self-adhering flashing at sill, jambs, and head for Pennsylvania’s driving rain conditions
- Exterior caulking — all perimeter joints sealed with paintable exterior caulk
- Hardware installation — deadbolt, handleset, and viewer installed and adjusted for smooth operation
- Weatherstripping — compression or wiper weatherstripping on all three sides for tight air seal
Entry Door Materials:
- Fiberglass entry doors — the most popular choice for South Central PA; excellent insulating value (up to 5x more insulating than wood); won’t warp, rot, or rust; available in wood-grain and smooth finish; Therma-Tru and Masonite are FTL’s most-installed brands
- Steel entry doors — strongest security; best cost-to-energy performance ratio; available in dozens of panel configurations; Pella and Andersen steel units installed regularly
- Wood entry doors — the premium aesthetic choice for period homes and high-end renovations; requires maintenance to prevent weather deterioration in PA’s climate; mahogany, oak, and Douglas fir options
Steel Security Door Installation Reinforced steel doors with multi-point locking systems and heavier gauge frames — for homeowners prioritizing maximum security at entry points. FTL installs steel security doors with proper frame reinforcement and multi-point lock hardware throughout South Central PA.
Storm Door Installation A properly installed storm door adds a secondary air barrier, protects the entry door from weather, and adds ventilation capability in mild seasons. FTL installs full-view, high-view, and retractable screen storm doors from Andersen, Larson, and Emco with correct drip cap and frame flashing.
Screen Door Installation Traditional hinged screen doors for wood-frame entries — properly sized, hung with spring closer hardware, and adjusted for smooth self-closing operation.
🌿 Patio Door & Sliding Glass Door Installation
Patio doors are among the most technically demanding exterior door installations — requiring proper threshold preparation, weathertight frame installation, and precise panel adjustment for smooth sliding or swinging operation:
- Sliding patio doors — two-panel sliding door systems with proper threshold, weatherstripping, and security bar hardware
- French patio doors — outswing and inswing double-door systems with astragal and multi-point hardware
- Multi-slide patio door systems — three and four panel sliding systems for wider openings
- Bifold patio doors — folding systems for large patio openings; maximum opening width for indoor-outdoor connection
🔧 Door Repair Services
Door repair is one of FTL’s most frequently requested services across South Central PA — and one where the right diagnosis matters as much as the repair technique:
Sticking and binding doors:
- Diagnosing whether the issue is hinge-related, seasonal wood movement, foundation settling, or frame racking
- Hinge tightening and resetting — resecuring loose hinges; installing longer hinge screws into the stud for hinge-pull failures
- Door planing — removing material from the binding edge for permanent clearance
- Strike plate adjustment — moving the strike plate to match the latch bolt’s actual position after settling
Latch and hardware issues:
- Latch bolt to strike plate misalignment — shimming hinges or adjusting strike plate mortise
- Deadbolt misalignment — adjusting door, frame, or strike plate to correct deadbolt engagement
- Lock replacement — replacing failed locksets with keyed or keyless options
- Hinge replacement — replacing bent, corroded, or worn hinge leaves
Weatherstripping and sealing:
- Weatherstripping replacement — foam, pile, compression, and wiper weatherstripping on all door styles
- Door sweep replacement — bottom door sweep replacement for draft elimination
- Threshold replacement — worn or damaged threshold replacement on exterior doors
- Door bottom seal — automatic drop seals for improved air sealing
Frame and jamb repair:
- Rotted door jamb repair or replacement — common on exterior doors in older South Central PA homes
- Split or cracked door jamb repair — structural repair of damaged jamb sections
- Door frame squaring — resetting out-of-plumb frames caused by foundation movement
- Strike plate reinforcement — installing reinforced strike plates and door jamb armor for improved kick-in resistance

What Sets FTL Door Installation Apart
🎯 Precision Shimming & Reveal Setting A door hung without proper shimming will rack out of square the moment the framing settles — producing uneven reveals, binding, and latch misalignment. Every FTL door installation uses proper shim placement at all three hinge locations and the latch side, fastened through the shims into the rough framing for a permanently plumb, stable installation.
🔩 Strike Plate Accuracy The most common door installation failure is a latch bolt that misses the strike plate by 1/8″ — resulting in a door that requires force to latch or doesn’t stay closed. FTL sets every strike plate mortise by testing the actual latch bolt position rather than assuming the printed measurements are accurate — the difference between a door that works perfectly and one that requires adjustment in 30 days.
🌡️ Weathertight Exterior Installation Pennsylvania’s driving rain, freeze-thaw cycles, and wind pressure demand proper flashing and weatherstripping on every exterior door installation. FTL’s exterior door installations include self-adhering sill pan flashing, head flashing, perimeter caulking, and properly adjusted weatherstripping — eliminating the air and water infiltration that compromise energy performance and lead to frame rot.
🪵 Trim Included Every FTL door installation includes casing installation on both sides of the opening — the interior trim that finishes the gap between the door frame and the wall. Many door installers charge extra for trim or leave the homeowner to finish it separately. FTL includes paint-ready trim as part of every door installation.

Door Installation FAQs — Harrisburg & South Central PA
How much does door installation cost in Harrisburg, PA? Interior hollow-core door installation starts at $175 in South Central PA. Exterior entry door installation starts at $350 for labor — door unit priced separately. Barn doors with hardware typically run $350–$600 installed. Patio door installation starts at $550 for labor. All pricing confirmed with a free written estimate — call 1-223-243-7550.
What is the difference between a pre-hung door and a slab door? A pre-hung door is a complete unit — door panel, frame, hinges, and stop molding all pre-assembled, ready to set into a rough opening. It’s the correct choice when replacing an existing door and frame together. A slab door is just the panel — installed into an existing frame. Slab installation requires more skill because the door must be planed to fit, hinges mortised or matched to existing locations, and the latch bore drilled precisely.
What is the best exterior door material for Pennsylvania? Fiberglass entry doors perform best in Pennsylvania’s climate — they don’t warp, rot, or rust the way wood and steel can under repeated freeze-thaw exposure; they insulate up to 5x better than wood; and they’re available in realistic wood-grain textures that look premium. Steel doors are the best choice where security is the primary concern. FTL advises on the right material for your specific application during your free estimate.
Why is my interior door sticking? Sticking doors in South Central PA homes have four common causes: hinge screws pulling out of the jamb (the most common); seasonal wood movement as humidity changes throughout Pennsylvania’s seasons; the door expanding after painting; or foundation settling causing the frame to rack out of square. FTL diagnoses the actual cause before repairing — ensuring the fix is permanent rather than temporary.
Can you install a barn door where there’s no wall space beside the opening? A barn door requires wall space equal to the door width on the latch side for the door to slide fully clear of the opening — if that space doesn’t exist, a pocket door is typically the better solution. We assess wall space and structural conditions during the estimate and advise on the right sliding door option for your specific opening.
Do you install door casing trim as part of the installation? Yes — casing installation on both sides of the opening is included in every FTL door installation. We install the casing, fill nail holes, and leave every door in a paint-ready condition. Many contractors leave the trim to the homeowner; FTL delivers a complete, finished installation.
Can you replace all the interior doors in my home at once? Yes — whole-home interior door replacement is one of our most efficient projects because we can stage the installations room-by-room in a single visit, minimizing disruption. Replacing all interior doors at once with matching hardware and profiles produces a cohesive, upgraded appearance throughout the home. We provide a written estimate per door and a whole-home total before any work begins.
Do you install fire-rated doors for commercial applications? Yes. FTL installs UL-listed fire-rated door assemblies for commercial projects requiring rated construction — including 20-minute, 45-minute, 60-minute, and 90-minute assemblies. Commercial door installations are available for tenant improvements, office renovations, and commercial build-outs throughout South Central PA.
