Improving Energy Efficiency with New Windows in Maryland Homes

Why Older Windows Waste More Energy In Maryland

A lot of Maryland homes, especially older rowhomes and colonials, lose conditioned air through windows that were never designed for today's expectations.

Signs you may be losing efficiency include rattling sashes, visible gaps, hard-to-open panes, and rooms that never seem to match the thermostat.

The Features That Matter Most In Energy Efficient Windows

A good replacement starts with the right combination of frame material, glass package, and installation method.

What To Expect During The Project

What Separates A Solid Installation From A Problem Project

That is why contractor selection matters almost as much as product selection.

If a contractor cannot clearly explain the sequence of work, that is usually a warning sign.

A few practical questions are worth asking before you sign anything:

• Will the company do insert or full-frame replacement, and why?
• What steps will be used to protect trim, finishes, and possible lead paint?
• Does the bid include finish work, insulation, and disposal, or are those extra?
• Who handles permit coordination if the job requires it?
