Accurate measurements of the opening, headroom, side room and back room so the right door and track fit the first time.
A garage door that is the wrong size causes endless trouble. Doors are made to the width and height of the opening, and the tracks must fit the space above and beside the door. Getting those numbers right is the most important step in any new door project. Homeowners in Nashville ask us to measure before they shop, before they order online or when an older opening does not match standard sizes.
We measure the width and height of the opening at several points, since older framing is often not square. We measure the headroom above the opening, the side room on each side and the depth of the garage, and note obstructions such as pipes, lights, openers and ceiling beams. From those numbers we determine the door size, the track type, the spring type and the opener choices that fit. You receive the measurements in writing.
Width and height are measured in several places, because framing can be out of square and a door must fit the smallest dimension.
Standard tracks need room above the opening. Low-headroom and high-lift setups need different hardware, and we check what fits.
Each side needs room for the track and the door must have room to travel back into the garage.
Pipes, lights and beams can block the track path, and we note and plan around them.
