Security Screen Doors in Portsmouth, NH

There is no single best one, which is why this site scores contractors instead of crowning a brand. What separates a real security screen door from a decorative one is third-party forced-entry testing — ASTM F3561 in the US, AS5039 for Australian-origin systems like Crimsafe — plus a screw-clamped mesh retention system rather than a rubber spline. Ask for the test report number, not a brochure.

A security door is a solid or barred door that replaces or covers your entry door. A security screen door keeps a fine steel mesh in a reinforced frame, so you still get airflow and a clear view out while the opening stays protected. Security screens cost more than decorative wrought-iron doors and less than a full impact-rated door replacement.

Installed prices in Portsmouth typically run $900 to $2,800 for a standard front-door unit. Nationally, security doors average around $1,190 with most homeowners paying between $560 and $2,900, and professional installation adds roughly $200 to $650. Premium stainless-mesh systems such as Crimsafe generally start near $1,000 per opening and rise with size, color and sliding-door configurations.

Big-box installation is quoted per job after a measure, and the door itself is usually a stock size. That works when your opening is standard and you want the lowest price. It does not work for out-of-square openings, sliding patio doors, or when you need a tested system with a documented mesh spec — those are custom-fabricated and go through a local specialist.

A tested system raises the time and noise cost of forced entry enough that most opportunistic attempts are abandoned. It is not a vault door. Worth knowing: US burglary is at the lowest rate on record — 229.2 per 100,000 in 2024, down 69% since 2005 — so if crime is your only reason to buy, be honest about that in your budget.
