Picking the door for your house
An insulated door on an attached garage pays its own way over the life of the door, because the garage pulls less heat out of the mudroom and the house. Our technician walks the choice with you against the opening, the room above the door, the floor and what the existing door told us.
Single-layer steel is a plain stamped skin on a frame: light, least costly, and lets heat through. Double-layer steel adds foam insulation inside and a vinyl backer. Triple-layer steel is skin, foam core and a second steel skin, which is the most insulated and the quietest. Composite doors are a frame with molded facings that look like wood planks without the maintenance. Wood doors are custom carpentry, heavier than steel, and need a finish schedule. Carriage house styles cover any of those builds: swing-look hinges, strap plates and often a row of top-section windows. The insulation core is the foam between the skins; thicker and denser cores keep more heat in and more noise out.
| If you want | Look at |
|---|---|
| A quiet door, especially under a bedroom | Triple-layer steel with a foam core |
| A warmer attached garage in January | Insulated double- or triple-layer steel, with a tight bottom seal |
| Low upkeep with a wood look | A composite door |
| Windows for daylight in the garage | A top-section window row, insulated glass on an attached garage |
| A look that matches the house | Carriage house styling on a brick house, or a plain long-panel on a ranch |
What installation day looks like
1. Measuring and checking the opening
The technician measures width, height, headroom above the open door, backroom from the door into the garage, and the side room on each jamb. We check the floor for level, the jambs for plumb, and the header for straight. A new door needs the opening close to square; we flag any out-of-true that will show after the door is up.
2. Releasing tension and removing the old door
The spring tension on the existing door is released first; this is the technician's work, with winding bars and the door in the right position. The sections come down one by one, the track unbolts from the jambs, and the old opener comes down if it is being replaced too. Taking out the old door is covered in detail there.
3. Tracks and the first section
New vertical tracks go up with the jamb brackets, plumb and spaced for the new rollers. The bottom section goes in first, with the bottom seal and the two bottom roller brackets. The bottom brackets stay under spring tension for the life of the door, which is one reason their work belongs with a technician.
4. Stacking sections and hinges
The next sections stack on top of the first, each one bolted to the one below with hinges that carry the rollers. We check level and square at each section, because an error at the bottom only grows as the door builds up.
5. Springs, cables and balance
The horizontal tracks and the spring shaft go in above the door. Springs are sized to the door's weight; the right spring makes the opener's job small. Cables run from the bottom bracket to the drums at the ends of the shaft. The technician winds the springs with winding bars, lifts the door to check balance, and adjusts if the door drifts from halfway.
6. Opener hookup, or a new opener
If your opener is coming along, we hook it to the new door, reset travel and force to the new weight, and run it. If you have asked for a new opener, the opener install folds in here. A heavier insulated door often earns a bigger opener head, and we flag that at the quote.
7. Reversal test and walk-through
A two-by-four under the door tests the reversal. The door should come down, touch the wood and reverse. We walk the door with you, show you the new seals and where the new weather stripping meets the jamb, and hand over the paperwork.
Repair this door or install a new one
When a new door earns its keep
- The door is a flat uninsulated steel skin on an attached garage, and the heat loss shows
- The door has been patched one section too many
- The spring is on its third replacement, and parts for the model are running thin
- You want a style the current door cannot give you
When keeping the current door makes sense
- One section is damaged and the rest is sound: one-section work is often the right call
- The door is fine and the opener is the problem
- Only the bottom seal has gone and daylight is the issue
How do we tell at the door? We look at the sections, the tracks, the springs and the hinges together. The fix or replace question walks through the call in more detail.
What our installers bring on install day
A new-door visit usually carries the door sections, matching tracks, springs sized to the weight, cables, rollers, bottom brackets, bottom seal, side and top stop molding with weather strips, hinges, lag screws and the tools: winding bars, drill, level and the opener if that is being swapped too. On a non-standard opening, extras like shims and jamb trim come along.
