193.9%2024 national estimate
Zonda / Journal of Light Construction
The 2024 Cost vs. Value Report estimated a national average cost-recouped figure of 193.9% for its specified garage-door replacement project. This historical project estimate is not a measured return for every homeowner or garage door.
Why it matters: Resale results depend on the property, local market, project scope and sale timing. This figure is not a guarantee that a replacement will pay for itself.
For the C.H.I. Carriage House Doors: the report does not evaluate this exact model. Compare appearance, specifications and installed cost for your home rather than applying the national percentage to your quote.
U vs Rdifferent test methods
Door & Access Systems Manufacturers Association
DASMA distinguishes calculated door-section R-value from tested assembled-door U-factor. Higher R-value and lower U-factor indicate greater resistance to heat transfer within their respective methods. The two garage-door metrics are not directly comparable or simple reciprocals.
Why it matters: Compare thermal figures measured on a consistent basis. Glazing, joints, seals and the rest of the garage also affect comfort; insulation alone does not control indoor temperature.
For the C.H.I. Carriage House Doors: request the thermal documentation for the exact configuration. Do not assume a published collection maximum applies to every size, glazing option or insulation tier.
Windwhole-assembly planning
FEMA
Garage-door failure during high winds can allow internal pressurization that increases loads on other parts of a building. Wind resistance depends on the complete door assembly and its installation.
Why it matters: Select a documented configuration suitable for the site’s design requirements. Reinforcement must follow manufacturer instructions or an appropriate engineered design; a generic bracing kit is not suitable for every door.
For the C.H.I. Carriage House Doors: confirm the exact size, design pressures, reinforcement, anchorage and applicable installation documentation. No door or retrofit guarantees protection from every storm.
Cyclesnot a lifespan guarantee
Door & Access Systems Manufacturers Association
One spring cycle is one complete opening and closing. Cycle ratings describe design duty, not guaranteed service life. Actual performance depends on spring selection, installation, use and operating conditions.
Why it matters: Compare documented cycle ratings and suitability for your door. Do not decide that a spring needs replacement solely from its age.
For the C.H.I. Carriage House Doors: a trained technician must determine spring specifications from the actual door and configuration. A spring cycle rating is not a rating or lifespan guarantee for the complete system.
