Entry, patio, French and storm doors. Exterior doors only.

A front door should close with one hand, seal out the weather and look like it belongs on your home.

Quick answer

The ACM Pros install exterior doors across North Alabama: entry doors, patio and sliding doors, exterior French doors and storm doors. Every door is set over a sloped, sealed sill pan with flashing, so water drains out instead of rotting the threshold. We install exterior doors only, never interior doors.

The details

Exterior doors we install

Entry doors
Your front door carries the most use, the most weather and most of your home's first impression. We install fiberglass, steel and wood entry doors, with sidelights or a transom if you want more light.
Patio and sliding doors
Large glass doors that open onto a deck or patio. Sliders cost less, need no room to swing and give the most glass for the opening.
Exterior French doors
A hinged pair that meets in the center, with one active door and one usually held shut by flush bolts. Both can open for a wide clear opening, and they seal better than a slider because they press against the frame.
Storm doors
A second door mounted outside the front door. On an exposed entry it takes the weather off the main door, and it adds ventilation.

Why doors fail here before windows do

A door is the hardest-working opening in a house. It gets opened thousands of times a year, it carries its own weight on hinges, and its threshold sits at the one place where water collects.

Humidity swells wood doors and warps them out of shape, which is why the door that closed cleanly in February drags in August. Fiberglass and steel do not move the same way.

Threshold rot is the most common failure we see, and it is almost always an installation problem rather than a product problem: no sill pan, or flashing lapped the wrong way.

How we install an exterior door

Sill pan
Every exterior door we set gets a sloped, sealed sill pan with end dams, the raised ends that stop water running off the sides. This one detail decides whether the threshold framing is still sound in ten years.
Flashing and drainage
Head flashing above the door, side flashing lapped over the pan, and the weather barrier behind the siding tied in so water sheds outward.
Squaring and reveal
The frame is set plumb, with an even reveal (the gap between door and frame) top to bottom, so the weatherstrip presses evenly all the way around. An uneven reveal is why a new door still whistles.
Hardware and strike
Strike plates screwed into the framing, not just the jamb trim. Long screws at the hinges on any door that carries real weight.

Why the sill pan matters most

The sill pan is the step most often skipped, because nobody can see it once the door is in. It is also the reason a threshold fails from underneath when it is missing.

When an old door has been leaking at the threshold, we photograph any rot and show you before the framing is rebuilt and the new door goes in. Nothing gets covered up.

Before you replace: three things worth checking

A sticking door
Often a hinge problem. Long screws into the framing at the top hinge fix a surprising number of doors that seem to need replacing.
A drafty door
Often a weatherstrip problem. The seals wear out and can be replaced on most doors.
A hard-to-slide patio door
Usually worn rollers and a dirty track. Cleaning and new rollers cost a fraction of a new door. We check that first, and we will tell you if that is all it needs.

Sun, color and storm doors

A dark door on a south or west entry with no overhang will move more than the same door in shade, which is worth knowing before you pick a color.

A full-glass storm door in front of a dark entry door can trap heat between the two, sometimes enough to warp the door it was meant to protect. A ventilated or partly screened storm door releases that heat and removes the risk.

What affects the price

We price after measuring, line by line, with the materials named. These are the things that move the number.

  • Door type and slab material
  • Glass package
  • Sidelights or transom
  • Whether the frame and threshold come out
  • Hardware grade and finish
  • For patio doors: opening width and number of panels

Questions people ask

Can you replace a door without disturbing the trim around it?

Sometimes. A slab-only replacement (a new door hung in the existing frame) keeps the trim if the frame is sound. But if the threshold or jamb is soft, the frame has to come out, and the trim around the door comes off with it and is replaced as part of the job. We tell you which before we quote.

Which material lasts longest on a front entry?

Fiberglass, in most cases, because it does not move much with temperature and does not need refinishing. Steel is stronger against impact but dents permanently and can pass heat through. Wood is the right answer where the architecture requires it and the entry is sheltered.

What actually keeps the threshold dry?

A sloped sill pan with a raised back edge, flashed and lapped so gravity drains water out instead of into the framing. It is invisible once the door is in, it is the step most often skipped, and it is the reason a threshold fails from underneath.

Is a storm door still worth installing?

On an exposed entry with no overhang, yes. It takes the weather off the main door and extends the life of its finish. On a sheltered entry or covered porch, it mostly adds another thing to maintain.

Will a storm door damage my entry door?

It can, on a sun-facing entry. The gap between a full-glass storm door and a dark door behaves like a small greenhouse. A ventilated or partly screened panel releases that heat and removes the risk.

My sliding patio door is hard to move. Replace or repair?

Often a track cleaning and new rollers fix it for a fraction of the cost, so we look at that first. If the frame is racked or the sealed glass has failed, replacement is the honest answer.

Sliding or French doors for a patio?

Sliding doors cost less, need no room to swing and give more glass for the opening. French doors give a wider opening when both open and seal better, because they press against the frame instead of sliding past it. The room you have for the doors to swing usually decides it.

Do you install interior doors?

No. We install exterior doors only: entry, patio and sliding, exterior French and storm doors. We do not install interior doors or interior windows, and we do no work inside the house.
