What to Ask Before Hiring a Window Installer in Baltimore

Begin By Defining The Job Clearly

The first question is simple: what, exactly, is being replaced or repaired? A contractor who has done real field work will usually slow down here, look at the opening, and explain whether the frame, sash, sill, and surrounding masonry are staying in place.

Is this a repair, a restoration, or a replacement? Will the existing frame stay, or is this a full tear-out? What happens to trim, casing, paint, and interior drywall? Who is responsible for haul-away and cleanup?

If the answers stay vague, that is usually a warning sign.
