Choosing Licensed Window Replacement Contractors in Montgomery County, MD

Why Licensing Matters Before You Sign

What To Verify Before You Hire

The first pass is not about collecting brochures. It is about confirming that the contractor is licensed, insured, and actually handles the kind of work you need.

A practical vetting process usually covers a few items that should never be skipped:

License status and scope of work Proof of general liability and workers' compensation, not just a verbal assurance Local project experience Written proposal Who will pull permits, schedule inspections, and close the job properly if the work requires it

Local Rules That Can Change The Job
