[Request Inspection](https://cmac-new-concept.vercel.app/quote) ## Residential Garage Doors, clearly scoped. CMAC handles the full range of residential garage door work: retail sales and upgrades, new construction installation, insurance claim services, and repairs. Whether you are replacing a twenty-year-old builder-grade door, specifying doors for a house under construction, or working through a claim after a storm or an impact, the process starts with a free, no-obligation inspection. It is worth being blunt about what a garage door is. It is the largest moving object in most houses, it cycles thousands of times over its life, and it is usually the single biggest element of the front elevation. Replacing a tired door changes how the house reads from the street more than almost any other exterior item at a comparable scope of work. ## How a sectional door is actually built A modern residential door is sectional: four or five horizontal panels hinged together, riding rollers in a vertical track that curves back into a horizontal track under the ceiling. That hinge line is what lets a door eight feet tall live in a garage with a seven-foot ceiling. The counterbalance — almost always a torsion spring on a shaft above the opening — carries the weight so the opener only has to move a nearly balanced load. The track radius matters more than it sounds. Standard radius track needs the most headroom. Low-headroom track uses a tighter curve and a double-track arrangement for tight garages. High-lift track raises the door further before it turns horizontal, which is what you want in a garage with a lift or tall ceilings. Getting this wrong at the specification stage is expensive to fix later. ## Single, double, and triple-layer steel Single-layer steel is one skin with no insulation — the least expensive option and the loudest. Double-layer adds polystyrene bonded to the back of the skin. Triple-layer, sometimes called sandwich construction, puts insulation between two steel skins, which makes the section stiffer, quieter, and far more resistant to the dents and flex that show up on thin single-skin doors. R-value measures resistance to heat flow; higher is better. It is genuinely relevant on an attached garage, because that garage shares a wall with the house and often sits under a bedroom. A garage that runs near outdoor temperature all summer pushes heat through that shared wall around the clock. An insulated door does not make the garage conditioned space, but it narrows the swing and takes load off the adjacent rooms. It also cuts noise — both the door operating and everything happening outside. > Compare R-values only between doors tested the same way. A number quoted for the insulation alone is not the same as a number for the assembled section. ## Windows, style, and hardware Window sections are the fastest way to change the character of a door. Placement is a design decision: the top section is standard and delivers daylight without giving anyone a view of what is in the garage, while full-view glass turns the whole door into a wall of light. Glass options run from clear to obscure, tinted, insulated, and frosted. Obscure glass is the usual answer when you want the light but not the sightline. Hardware follows the same logic. Heavier doors need heavier hinges, longer-stem rollers, and thicker track. Nylon rollers with sealed bearings run noticeably quieter than the plain steel rollers packed with entry-level doors, and they are one of the least expensive upgrades available at installation. ## New construction and insurance claims On new construction, the door goes in after the opening is framed and the header is verified. Coordinating early lets the opening, the headroom, the backroom, and the electrical rough-in match the door and operator actually being installed rather than forcing a compromise at the end of the job. On insurance work — hail, wind, or vehicle impact — CMAC handles claim documentation and meets with the adjuster. Damaged sections, bent track, and a bowed door that no longer seals are all documentable conditions. Bring the claim number and the inspection report to the same conversation and the process moves considerably faster. ## What residential garage doors includes ### Retail sales and upgrades Replacement doors and upgrades for homes with an existing opening. ### New construction installation Door and opener specified alongside the framing rather than after it. ### Insurance claim services Damage documentation and adjuster meetings handled as part of the job. ### Garage door repairs Springs, rollers, track, cables, and sections serviced without a full replacement. ### Insulated construction Double and triple-layer steel options that quiet the door and buffer an attached garage. ### Free inspection A no-obligation look at the door, the balance, and the hardware before anything is quoted. ## The CMAC process for residential garage doors 1. **Schedule** — Tell us what is happening at your property. 2. **Inspect** — We document the property and affected systems carefully. 3. **Plan** — Review a clear scope and written proposal. 4. **Build** — The CMAC team completes the approved work. 5. **Confirm** — A final walkthrough closes out the project. ## Systems and manufacturers - **Clopay** — Residential and commercial sectional doors - **Wayne Dalton** — Residential and commercial doors - **Amarr** — Residential and commercial doors - **Northwest Door** — Custom wood and steel doors ## Residential Garage Doors questions ### Can I replace a garage door spring myself? You should not. A torsion spring on a double door stores enough energy to cause severe injury or worse if it releases while being handled, and the winding process requires the correct bars and technique. This is the single most common source of serious DIY injury in residential maintenance. Call a technician. ### My garage door will not close and reverses instead. What is wrong? Nine times out of ten it is the photo-eye safety sensors near the floor — either misaligned, dirty, or with a blocked beam. Check that both indicator lights are steady and that nothing is in the path. If the lights are steady and it still reverses, the issue is more likely the down-force setting, an obstruction in the track, or a failing opener logic board. ### Does CMAC offer emergency service? Yes, for the situations that genuinely cannot wait: 24/7 emergency response for water mitigation, and 24/7 emergency garage door repair.
