How to Verify an MHIC-Licensed Window Contractor in Baltimore

Before you compare styles, prices, or lead times, make sure the contractor is actually authorized to do the work.

A valid MHIC license tells you that the contractor is registered with Maryland’s home improvement system and can legally perform covered residential work.

If a contractor hesitates, changes the subject, or cannot produce the number cleanly, treat that as a warning sign.

What An MHIC License Does And Does Not Tell You

For homeowners, the main value is simple: it shows the contractor is supposed to be playing by Maryland’s rules.

The best use of the MHIC number is as a first pass, then you build from there with proof of insurance, recent local work, and a written scope of work.

For homeowners trying to sort through bids, that sequence matters more than a flashy sales pitch.

The Simple Verification Steps That Matter

Start by asking for the contractor’s MHIC license number and the exact business name that matches it.

Then compare the name on the estimate, contract, and business card against the license record.

If the record is expired, suspended, or missing, stop there and sort it out before you hand over a deposit.

It is also smart to request proof of general liability insurance and workers’ compensation, if the company has employees.

If you are comparing bids for full-frame replacement or insert projects, find out who is doing the install, whether it is an in-house crew or a subcontractor, and who supervises the job.

An experienced window replacement company can confirm the cause with a quick inspection.

That single conversation often reveals more than the license check alone.

Ask these questions before you sign:

• What is your MHIC license number, and is it under the exact business name on the contract?
• Who will pull the permit, if one is required, and who handles inspections?
• Will the same crew install the windows, or will subcontractors be involved?
• How do you handle rot, lead-safe work, or hidden damage discovered after removal?
• What labor warranty do you provide, and what is left out of it?
