Door and Window Installation in Birmingham, AL
Installation, Replacement, and Other Services Made Simple and Easy

Drafty windows, a door that sticks or won’t seal, daylight showing around the frame, these aren’t just annoyances. Failing doors and windows leak conditioned air, let water in, and quietly raise your energy bills every month. Reliable installs and replaces doors and windows so your home seals up tight again.
The seal is the whole point
A window or door is only as good as its installation. A poorly set unit leaks air and water no matter how good the product is. We install for a proper seal, correct flashing, insulation, and trim, so the fix actually lasts and lowers your energy loss instead of just looking new.
How Reliable does it

- Replacement windows, all types

Why homeowners trust Reliable with it
Reliable has installed doors and windows across the Birmingham metro since 1992, a licensed home builder (#24104), insured, GuildMaster-certified. We install for the seal, not just the look.
Investing in Doors and Windows?
We want to make sure the people we service understand truly how important these seemingly mundane parts of our homes are.
While you might know that new door can increase your home’s safety and security, what you might not realize is that it also gives you a chance to experiment with a brand new aesthetic, enhancing curb appeal and improving home value. Other advantages of installing new doors and windows are:
- Increasing energy efficiency, as doors are where the most significant amount of heat in a home is lost. This means less money being spent on your energy bills!
- Giving your home a facelift without breaking the bank, since doors typically aren’t as expensive as countertops or flooring.
- One of our favorite reasons to change up your window situation is because of Low-E Glass, a material with a greenish tint that not only reduces the amount of UV radiation that enters your home, but as a result lowers the cost of your energy bills! There are other types of window alternatives, such as laminated or gas-filled windows, but rest assured that Reliable will help you find out what best fits your remodeling budget.
- Windows aren’t typically what people think of as what adds value to a home. But with the right pieces of glass and trim, it can take a remodel project from zero to hero!
