Door repair

Commercial door repair

Request commercial door repair for a storefront, office entrance or shared building door that drags, sticks or will not latch. Describe whether the trouble began suddenly or developed over time. Photos of the hinges, frame, lock and closer help identify which components need inspection. The repair scope depends on the condition of the complete opening, so include a full view as well as close-ups.

Residential door repair

Arrange residential door repair for an entry or apartment door with loose hinges, an uneven gap or a latch that misses the strike. Tell us whether the door closes normally before it is locked and whether rubbing changes with the weather. A technician can assess alignment, hardware and frame condition to determine whether adjustment, component replacement or a replacement door is appropriate.

Door installation and replacement

Entry door installation

Request an estimate for entry door installation or replacement with photos of the existing door, frame and threshold. Include approximate opening dimensions and the direction the door swings. Tell us whether you want to keep the existing lock or add connected entry equipment. Door material, frame condition, finishing work and hardware compatibility all affect the proposed scope and installation price.

Storefront door installation

Plan storefront door installation for a shop or commercial entrance by sharing full-width photos and the opening dimensions. Identify whether the entrance uses a single door, a pair of doors or surrounding glass panels. Let us know about existing access control, closers and exit hardware. These details help prepare a replacement plan that accounts for the entrance as a complete system.

Access control installation

Get an access control installation estimate for key fobs, card readers or a keypad entrance.

Intercom repair

Book intercom repair for a buzzer that does not ring, one-way audio, a missing video image or an entrance that will not unlock. Explain whether the problem affects one apartment or every user.

Request security camera installation for entrances, delivery areas or other property locations you need to monitor.

CCTV camera repair

Arrange CCTV camera repair when a camera goes offline, recorded footage is unavailable or authorized phone viewing stops working. Tell us whether live video still appears at the recorder and whether one or all cameras are affected. Include the camera and recorder models when available.

Commercial door hardware

Door closer repair

Schedule door closer repair or replacement for an entrance that slams, closes too slowly or fails to latch. Send a photo of the closer, its arm and the full doorway, and mention visible oil leakage or loose mounting points.

Panic bar installation

Request an estimate for panic bar installation or replacement on a commercial exit door. Include photos from both sides, the door material, approximate dimensions and labels on the existing hardware. Mention any alarm or access-control connection. The proposed hardware needs to match the door and the required exit operation; a property-specific review is needed before selecting components or confirming the installation scope.
