Armstrong is committed to providing quality replacement doors and entry doors the professional way. Our fiberglass and steel entry doors are energy efficient, built to the highest quality standards and give you a superior alternative to consumer-grade replacement doors that are sold through home improvement retailers.

Energy-Efficient Doors

All front entry doors qualify for the ENERGY STAR® program. ENERGY STAR was created by the U.S. EPA and Department of Energy to help consumers identify products that save energy and money and protect the environment. We are proud that each one produced is an ENERGY STAR door.

Installing these energy-efficient products will save you money on heating and cooling costs, improve interior comfort and increase the value of your home. Armstrong’s professional class doors are made from the highest quality materials, starting with 20-gauge galvannealed steel that gives you 49% more steel than consumer-grade products. This exceptional durability is endorsed as “the door preferred by America’s top remodelers” and is backed by a lifetime limited transferable warranty.

State-of-the-art methods of customization make it possible for you to create an entry door that is made to order for your home. Our thousands of satisfied customers in the Bay Area, including San Jose, San Francisco, Oakland, Fremont, Santa Rosa and Sunnyvale, have never regretted having Armstrong Doors replace their original entry doors with one of our custom-made professional class doors.  Ask our professional estimators about how to choose the size, color, glass and hardware of your choice for an end result that will set your home apart for years to come.

Replacement Doors Tailored for Your Home

Nothing feels quite as good as well-tailored clothing, tailored to your size, shape and style preference. We’re not all S, M, L, XL and beyond. Off-the-rack clothing just doesn’t fit everyone’s measurements, form or silhouette. Similarly, off-the-rack doors fall short of expectations in the same way. Intuitively you know that a door made specifically for you must somehow be superior. And you are correct. But perhaps you don’t know how.

The materials, as well as the workmanship that go into custom made doors, is of exceptional quality and durability, and far exceeds what is available as ready-made. Unlike consumer-grade doors, professional-class doors are customized to your exact measurements for a better fit and more secure and energy-efficient door. Finally, every door is completed with painstaking detail and attention in the preparation and finishing of a door beautifully made expressly for you.

Real Protection

Flat roofed homes are unique and offer sleek lines, designed with style. However, flat roofs come with their fair share of problems.
