Replacing Old Building Entrance Doors: A Committee Checklist

Start with the problems you want to solve

Before comparing options, the committee should agree on what the old door is failing to do. Common issues include sagging frames, poor locks, drafts, corrosion, difficulty closing, or a look that no longer suits the building's facade.

Write these problems down in a short list. This list becomes the basis for every decision that follows, from materials to hardware, and it helps residents who were not involved in early discussions understand why a change is needed.

• Security and locking needs
• Weather exposure and corrosion
• Daily use, including wheelchair and stroller access
• Appearance and consistency with the building

Measure on site, not from old plans

Building drawings are often out of date, and an old opening may have shifted over the years. A professional on-site measurement records the actual width, height, frame depth, threshold level and wall condition. Measuring at more than one point is important, since walls are rarely perfectly square.

Ask the supplier to measure rather than relying on figures passed along by neighbors or previous contractors. Accurate measurements prevent costly rework and ensure the new door fits the opening as it actually is.

Choose the right material for the entrance

Iron and aluminum are both common choices for entrance doors, and each has strengths. Iron offers strong security and a solid feel, while aluminum is lighter and resists corrosion well. For a building entrance that sees heavy daily traffic, the committee should discuss weight, operation and maintenance together.

Ask about surface finishing as well. Hot-dip galvanizing and powder coating both extend the life of metal doors, especially in coastal conditions. Your supplier should explain the finish options in writing so the committee can compare them fairly.

Plan security, locks and access

The entrance door is the building's first line of defense, so security deserves careful planning. Decide who needs access, how residents will open the door, and whether the building uses an intercom, a video entry system or a key-based lock. The door and frame must be designed to accept the chosen hardware.

Coordinate with the electrician and the intercom provider early. Cable routing and hardware positions are easier to plan before fabrication than after installation.

Approvals, specification and signed approval

A written specification protects the committee and the contractor. It should describe dimensions, material, finish, glazing if any, hardware, opening direction and installation responsibilities. Attach photos of the existing door and any sketches showing the desired design.

Once the drawing and specification are final, obtain the committee's formal approval in writing. Check whether the building's bylaws or local requirements affect the design, particularly for the facade, and confirm the process with the relevant authorities where needed.

Installation, handover and maintenance

After production in the factory, the door is installed and adjusted on site. Good installation includes a level frame, properly fixed anchors, a smooth swing and tested locks. Ask the installer to walk the committee through the operation and to check the door in its final position.

• Test the lock and any automatic closer
• Confirm the threshold and weather seal
• Agree on a simple maintenance routine

Keep a copy of the specification and the maintenance instructions with the building's documents so future committees know what was installed.

Frequently asked questions

How long does it take to replace a building entrance door?

The timeline depends on production scheduling, the complexity of the design and how quickly approvals are given. Agreeing on the specification and approval steps early usually has the biggest effect on the overall schedule.

Should the committee choose iron or aluminum?

Iron generally offers a heavier, more secure feel, while aluminum is lighter and resists corrosion well. The right choice depends on the building's exposure, security needs and the look the committee wants.

Do we need to measure the opening ourselves?

It is better to have the supplier measure on site, since they will record the actual frame, wall and threshold conditions. Measurements from old drawings can be inaccurate.

Who should sign off on the final design?

The building committee should approve the final drawing and specification in writing. Check any bylaw or authority requirements that apply to the facade or entrance before signing.

Common mistakes to avoid

The most common mistake is ordering a door from old measurements or without a written specification, which leads to fit problems and disagreements. Leaving the lock and intercom decisions until after fabrication is another frequent cause of delays.

Our recommendation

Arrange an on-site measurement and a written drawing before the committee votes, and include the lock and intercom plan in the same specification. This single step prevents most of the problems we see in entrance door projects.

Summary

A successful entrance door replacement starts with clear goals, accurate on-site measurements and a written, approved specification. With those in place, the installation is straightforward and the result serves the building for years.
