Entry & Patio Door Replacement in Northern Delaware
A new entry or patio door is a fast, high-impact upgrade — better security, no drafts, and an instant curb-appeal lift — and once it's installed and sealed correctly it simply works for decades. For Northern Delaware homes, a properly flashed fiberglass entry door or a quality sliding/French patio door ends the cold-air leaks and sticking that plague old units. The installers we match you with handle the framing, flashing, and weatherstripping so the door seals tight the first time.

Frequently asked questions
How much does a new entry or patio door cost?
Entry doors typically run $1,500–$5,000 installed; sliding or French patio doors $2,500–$9,000 depending on size, material, and glass. Fiberglass offers the best balance of durability and efficiency.
Is a fiberglass or steel door better?
Fiberglass resists dents and won't rust, mimics wood grain, and insulates well — ideal for Delaware's humidity. Steel is more budget-friendly and very secure but can dent and rust at the edges over time.
How long does door installation take?
A standard entry-door swap is a few hours; a patio door is usually a half to full day, especially if the opening needs adjustment.
