Project Spotlight: Inside Look on Exterior Door Installation

Why did the homeowners replace their old door?

Their original patio door had rotted, letting in cold air and driving up energy costs. It also stuck during humid months, making it frustrating to use.

How did the new entry door improve their home?

The fiberglass design won’t warp or swell, and ComforTech glass improves insulation. Plus, the auto-adjusting threshold and Q-Lon weatherstripping seal out drafts, keeping their home cozy.

Were any extra features added?

The entry door we installed is a Heritage Single Entry Door with a 5 9/16″ frame depth, ensuring a solid, draft-free fit. The FrameSaver frame resists moisture damage, thereby eliminating the risk of future rot.

Installation included a Bronze ZAC Auto-Adjusting Threshold, preventing gaps that let in cold air. Q-Lon weatherstripping sealed out drafts, while a Snow Mist White interior and exterior brightened the entryway. The thumb-turn deadbolt and Georgian lockset provided extra security. The new entry door is built to withstand Boston’s harsh winters and humid summers, keeping the home comfortable and stylish year-round. Colonial grids gave this door a classic appearance!

How do entry doors protect New England homes?

Fiberglass doors resist swelling, shrinking, and rotting—common issues with wood. Impact-resistant frames help withstand storms, and weatherstripping locks out moisture and drafts.

What impact do entry doors have on a home’s value?

A fiberglass entry door has a 97.4% return on investment—one of the highest of any home improvement. It boosts curb appeal, lowers energy bills, and enhances security.
