Architectural & Fire Performance

Solid Core & Mineral Core Wood Door Solutions

Wood commercial doors offer high acoustic isolation, warm architectural aesthetics, and essential fire compartmentation in healthcare corridors, corporate suites, and educational facilities.

Heavy interior wood doors frequently sag on standard butt hinges, bind against frames, or fail positive latching checks required under NFPA 80. We realign sagged wood leaves, replace worn latchsets, repair chipped veneer edges, and install code-compliant mineral core replacement doors that retain original fire labels.

Wood Door Applications

  • Healthcare Corridors: Mineral core 20, 45, 60, and 90-minute fire-rated corridor doors.
  • Corporate Office Suites: Heavy solid core wood entry doors with lever locksets.
  • Acoustic & Conference Rooms: Sound-rated wood assemblies with dropped perimeter bottom seals.
  • Hospitality & Tenant Spaces: Prefinished architectural wood veneer door leaves and vision lights.
Common Failures

Wood Door Faults We Correct

Issues routinely addressed for office building and healthcare facility directors.

Hinge Sag & Door Binding

Hinge Reinforcement

Heavy solid core doors pulling screws out of wood frames or hollow metal jambs. Corrected via heavy-duty hinge shimming, thru-bolting, or continuous hinge retrofits.

Failed Positive Latching

NFPA 80 Citation Risk

Door closers failing to push the wood leaf far enough for latch bolts to seat into strike plates. We adjust hydraulic speed valves and realign strike alignment.

Unapproved Field Modification

Fire Label Void

Kick-down doorstops installed, or unapproved vision lights cut into mineral core fire doors. Corrected with certified hardware or properly labeled leaf replacement.

Edge Splitting & Veneer Damage

Armor Protection

High gurney or cart traffic chipping wood stiles and bottom edges. Resolved with edge guards, stainless kick plates, and protective armor plates.

Frequently Asked Questions

Wood Corridor Door FAQ

Can vision panels or windows be added to existing commercial wood doors?
On non-fire doors, vision frames can be field-cut. On fire-rated mineral core doors, cutting unapproved vision lights in the field voids the UL fire rating unless performed under certified factory guidelines.
Why do heavy wood corridor doors keep dropping on their hinges?
Solid core wood doors are heavy and place continuous torque on top butt hinges. Installing a continuous gear hinge distributes weight along the entire frame length, stopping door sag permanently.
What fire ratings are available for replacement wood doors?
We furnish wood doors with 20-minute particleboard cores as well as 45, 60, and 90-minute mineral cores that match existing architectural wood stains.
