Maryland door installation

A front door that closes like it means it.

Entry, French, and patio doors — measured by the owner or his son, and installed by the owner, an InstallationMasters™ certified installer who's on every job.

The one thing in your house you touch every single day.

Your front door is the first thing a guest touches and the last thing you close behind you at night. It's also the largest single opening in your wall.

A well-hung door seals, swings true, and latches without a shove — and still does all three in year eight.

A poorly hung one starts sticking by the second winter.

We'll help you pick.

Style. Color and finish. Glass and grid patterns. Hardware. Locking options. Whether it should match your windows or stand out from them.

It's the most visible decision you'll make on the outside of your house. Take your time with it — we're not in a hurry.

The door is half of it. The opening is the other half.

Most door problems aren't the door. They're the frame, the threshold, the shim job, and the seal.

A beautiful door hung in an opening that isn't square will drag, gap, and leak air no matter what you paid for it.

We measure the opening before we order anything — and the owner is on site when it goes in.

Worth noting

Front door replacement consistently ranks among the strongest projects for cost recovery in national remodeling surveys.

That's a nice bonus. Most of our customers replace a door because they're tired of the one they have.

Love the welcome.

The door you walk through coming home from work. The one your kids come through after school. The one that opens when someone rings the bell.

Worth getting right.
