Can New Patio Doors Improve Comfort in Baltimore’s Older Homes?

If the door opens onto a kitchen, sunroom, den, or basement level living area, comfort problems become even more obvious.

Signs The Existing Door Is Part Of The Problem

If you are trying to decide whether replacement is worth it, a few signs tend to show up again and again.

• A cold strip near the floor in winter
• Hot air or glare in the afternoon near the glass
• A door that sticks, drags, or never locks quite cleanly
• Visible condensation, rot, or damaged weatherstripping
