Door and Window Repair in Billings, MT

Describe the problem before choosing the repair

Give the contractor a description of what you observe. Identify the room, whether the unit opens, where you feel a draft, and whether the problem occurs during rain or when you operate the latch. Send a photograph of the whole opening and a close view of the damaged area. Ask the contractor to explain the proposed repair after inspecting it.

For air leaks, NorthWestern Energy advises homeowners to inspect windows and doors for daylight around the frame and to seal leaks with caulk, weatherstripping, or a door sweep. Ask the person quoting your work to identify the gap and specify which treatment they propose. Keep that draft repair separate from any proposal to replace the entire unit. [3]

For damaged glass, fogging, or a sticking window, ask whether the quote covers glass, operating hardware, the sash, or the complete frame. Request an explanation of why that scope fits the observed problem. If the contractor recommends replacement, ask for a separate repair option where they consider one feasible.

Check licensing and define responsibility

Montana’s Department of Labor & Industry states that construction contractors must hold a state license effective January 1, 2026. Its published definition includes businesses that undertake building alteration and repair, subject to statutory exemptions. Ask for the business’s current Construction Contractor License number and use the lookup linked from the state program page. Ask the program about any claimed exemption. [2]

Ask who will measure the opening, order parts, perform the work, and handle any subcontracted tasks. Request proof of insurance and a written description of the work. Include removal and disposal, interior trim, exterior finish work, and cleanup in your questions so you can compare the same scope across bids.

Billings says the owner must obtain permits or designate that responsibility to the contractor. If you delegate it, the city directs you to ensure the contractor obtains the appropriate permits and inspection approvals. Put the responsible person’s name in the agreement and request copies of the permit and approvals before closing out the job. [1]

Confirm the opening before ordering

Billings accepts building permit applications through City View, including applications for residential windows and doors. Its FAQ does not resolve every minor repair scenario. Describe your exact scope to the Building Division: hardware adjustment, glass work, complete replacement, or alteration of the opening. Ask which permit and inspection requirements apply before authorizing the order. [1]

For egress windows, the city FAQ lists a minimum opening area of 5.7 square feet, minimum opening height of 24 inches, minimum opening width of 20 inches, and a bottom sill no more than 44 inches above the floor. Treat these as a reason to confirm your project with the division, rather than as an ordering specification. Ask staff to confirm the applicable requirements and have the contractor document the proposed usable opening. [1]

Use the property address to establish jurisdiction. Billings directs people outside city limits to the State of Montana at 406-841-2056 for building permit information. Confirm the responsible office before applying, especially if your mailing address says Billings but you do not know whether the property lies within city limits. [1]

Compare quotes and arrange the work

The supplied sources do not establish a current local repair price range. Request itemized quotes instead of budgeting from an unsupported city average. Ask each bidder to separate labor, parts or glass, finish repairs, disposal, and permit charges. Have them state whether they charge for diagnosis and whether that charge counts toward approved work.

Distinguish the measurement visit, parts delivery, installation, and any inspection in the schedule. Ask how the contractor will secure the opening if they cannot complete the repair during the visit. For an exterior job, agree on a weather rescheduling policy and ask whether the chosen sealant has installation temperature or moisture restrictions.

For weather context, the National Weather Service’s Billings Airport report lists 1991–2020 normal precipitation of 1.36 inches in September, 1.37 in October, and 0.60 in November. Use the chart as background when discussing exterior work. Check the forecast for the actual appointment; these monthly averages do not establish a suitable installation day. [4]

At completion, operate each repaired door or window with the contractor present. Check the latch and lock, review the agreed finish work, and photograph the result. Request care instructions, warranty terms, and any inspection approval. Record unresolved items in writing before treating the work as complete.

Frequently Asked Questions

Does a minor door or window repair need a permit?

The city FAQ includes windows and doors in its permit application process but does not settle every hardware, sealing, or glass repair scenario. Describe the exact work to the Building Division and ask for a determination before starting. [1]

Can the contractor handle the permit for me?

Yes. Billings allows the owner to designate permit responsibility to the contractor. The city says the owner should ensure the contractor obtains the appropriate permits and inspection approvals. Record that responsibility in the agreement. [1]

Should I accept an old Montana contractor registration?

Ask for current license verification. Montana transitioned to construction contractor licensing on January 1, 2026, and converted active registrations held on December 31, 2025, to the new license. Verify the current record through the state program’s lookup. [2]

Should I replace a drafty window right away?

Start by asking for an air-leak assessment. NorthWestern Energy recommends inspecting frames for daylight and addressing leaks with caulk, weatherstripping, or a door sweep. Ask the contractor to explain whether sealing addresses your concern before approving full replacement. [3]
