Who makes C.H.I. garage doors

• Coach House, Inc. C.H.I. stands for Coach House, Inc. The company has made garage doors for homes and businesses since 1981.
• A Nucor company. C.H.I. is part of Nucor, and builds almost all of its residential doors from Nucor steel. The exceptions are Full-View Aluminum, and the wood and fiberglass overlays on Overlay Carriage House doors. C.H.I. says it makes all of its doors in the US.
• Sold only through dealers. C.H.I. doors, replacement parts and accessories are sold only through C.H.I. dealers, who install and service them. That is also where warranty claims go: to the dealer the door was bought from.

C.H.I. groups its residential doors into a Timeless Collection (Raised Panel, Stamped Carriage House, Stamped Shaker), a Contemporary Collection (Skyline Flush, Planks, Sterling), a Carriage Collection (Overlay Carriage House, Shoreline), Full-View Aluminum and Recessed Panel. We install every model in every collection, and C.H.I.’s commercial sectional doors too.

C.H.I.’s residential doors range from non-insulated 1-sided steel to 2-sided steel doors with polyurethane insulation. The highest rated are the overlay carriage house doors: the 5700 wood overlay at R 18.03, the 5800 fiberglass overlay at R 17.92 and the 5600 steel overlay at R 17.54. Planks, Skyline Flush and Shoreline polyurethane models are rated R 17.54, the Raised Panel 2216 and 4216 R 17.19, and polystyrene models R 7.94 to R 10.78.

From C.H.I.’s collection and model pages and its 2026 Timeless, Contemporary and Carriage Collection brochures (chiohd.com), checked November 2026. C.H.I.’s model pages list the wood overlay models at 2¾ inch; its brochure lists 2.5 inch sections for all overlay models. C.H.I. takes part in the DASMA Thermal Performance Verification program, and lists a tested U-factor of .19 for its 2 inch polyurethane models.

A lower gauge number means thicker steel: C.H.I. calls its 25 gauge 1-sided doors standard and its 24 gauge 1-sided doors heavy duty, and builds its 2-sided doors from 27 gauge steel on both faces.

Insulation: none, polystyrene or polyurethane

C.H.I. offers three insulation levels and says you may not need the highest one:

• Polystyrene works well, in C.H.I.’s words, for moderate climates, detached garages and simple vehicle storage. On 1-sided doors it sits behind the steel with a vinyl back cover; on 2-sided doors it is sealed between two steel skins.
• Polyurethane is denser and gives the highest R-values. C.H.I. recommends it for attached garages, harsher climates and garages used as workshops, gyms or living space, and says it also makes the door more resistant to vibration.
• No insulation can make sense for a detached garage or a door that stays open for long stretches.

C.H.I.’s own rule of thumb: if two or more of these apply, choose an insulated door. The garage is attached; your area gets very hot or very cold; you work or have hobbies in the garage; you keep pets there; or you plan to sell the house within ten years. Read more on insulated garage doors.

Style: match the house

• Traditional, colonial and ranch homes: Raised Panel, short or long panels.
• Carriage house look: Stamped Carriage House (embossed steel), Shoreline (wood look overlays), or Overlay Carriage House in steel, real wood or fiberglass.
• Shaker or craftsman look: Stamped Shaker or Recessed Panel.
• Modern homes: Skyline Flush, Planks, Sterling or Full-View Aluminum.

Windows, glass and color

• Windows: short, long, oversized and StyleLite windows depending on the collection, with inserts such as Stockton, Madison, Prairie, Sherwood and Sunburst. Skyline Flush and Planks windows can be stacked down one side.
• Infinity windows: a full-width tinted glass section, offered on Planks 2357 and 2358 and Skyline Flush 2157 and 2158 (one per door, not the bottom section) and on every Sterling door.
• Glass: plain, frosted, tinted, obscure and rain glass, plus seeded glass on some collections and designer glass (Temple, Newport, Florence) on select models.
• Colors: standard colors such as White, Almond, Sandstone, Brown, Bronze, Gray, Desert Tan and Black, which C.H.I. matches to Sherwin-Williams paint colors; Accents Woodtones, C.H.I.’s printed wood look finishes; and in-house powder coating in 188 colors. Not every color is offered on every model.

Wind load and openers

C.H.I. builds windload rated versions of many models; sizes and options vary by model. C.H.I. offers LiftMaster residential openers with its doors; see the LiftMaster openers we install.

The NFPA and other model codes recommend frequent drop testing of rolling steel fire doors, and C.H.I. designs its Guardian doors for simple, repeatable drop tests. See our rolling door drop testing service.

Commercial operators

C.H.I. pairs its commercial doors with LiftMaster operators: the Model J (jackshaft), Model H (hoist), Model GH (gearhead hoist) and Model T (trolley) with Logic 5.0, and the FDO-A and FDO-B in-line gear drive fire door operators.

C.H.I. gives most of its residential doors a limited lifetime warranty on the sections against splitting, cracking and rusting through, for as long as the original buyer owns the home. Springs are covered for 3 years and hardware for 6 years (3 years on 25 gauge 1-sided models). Sterling sections are covered for 5 years, and commercial sectional doors for 10 years. The warranty covers parts, not labor.

* For as long as the original purchaser owns the home, in single family residential installations. Doors bought and owned by an association, an ownership group or anyone other than the resident fall under C.H.I.’s commercial terms. On 2-sided and overlay carriage house doors, C.H.I.’s Lifetime Package extends the lifetime coverage to springs and hardware.

What C.H.I.’s warranty does and does not cover

• C.H.I. repairs or replaces defective parts. Shipping, installation and labor charges are not covered.
• Every warranty period starts on the date of manufacture, and the warranty cannot be transferred to a new owner.
• Excluded: rust from damage or scratches; corrosive chemicals or fumes, salt environments including coastal areas, condensation, water or fire; accidents, improper use, improper installation or maintenance and normal wear; defects in paints or coatings used to finish door sections; parts that were modified or are not part of the original door.
• Wood overlay doors must be finished to C.H.I.’s instructions before installation. Painting steel or fiberglass overlay doors a dark color (light reflectance value under 50%) voids the warranty unless the paint is Sherwin-Williams VinylSafe. C.H.I. also excludes damage from extreme heat and sun on black overlay doors.
• Report a defect to the dealer you bought the door from within 15 days of finding it. C.H.I. may inspect the part.

C.H.I. does not ask you to register the door: claims are processed with the door code assigned when the door is ordered, which is on your original purchase receipt. C.H.I. handles warranty claims through the dealer the door was bought from.

C.H.I. recommends looking a garage door over at least twice a year, testing the opener’s automatic reverse, keeping the moving parts lubricated and protecting the finish with gentle cleaning. It recommends professionals for all garage door repairs.

Twice a year: look it over

• Check the panels for rust or scratches in the paint.
• Check the springs and other moving metal parts for wear, cracks or rust.
• Check the track for warping or loose hardware, and wipe dust off the opener’s sensor lenses with a soft cloth.
• Lubricate the moving parts with the product the door’s care instructions recommend.

If you see any of these problems, call a technician rather than tightening or adjusting parts yourself.

Test the opener and the balance

1. Close the door with the opener and carefully wave something past the photo eyes as it comes down. The door should stop and reverse. If it does not, stop using the opener and have it serviced. Follow your opener’s manual for its safety reversal test.
2. With the door closed, pull the opener’s release and lift the door by hand. A balanced door with straight track lifts easily and stays in place when you let go halfway up.
3. If it drifts up or down, is hard to lift, or a spring looks broken, leave it closed and call us.

Protect the finish

• Powder coated doors: clean gently with a mild soap or a cleaner listed as safe for the finish. C.H.I. warns that industrial solvents and household chemicals can damage powder coating.
• Repainting a steel door: C.H.I.’s instructions are to wash it with trisodium phosphate (TSP), buff lightly with extra fine steel wool, prime any rust or bare metal with a zinc based primer, then paint with a premium oil base or latex exterior paint, testing a small area first.
• Steel and fiberglass overlay doors (5300, 5500, 5600, 5800): repaint with a premium exterior 100% acrylic water based paint; C.H.I. recommends Sherwin-Williams Resilience. Remember the dark color rule in the warranty above.
• Wood overlay doors (5400, 5700): finish every edge, including the section joints, before installation; C.H.I. says unfinished edges void the warranty. Natural wood needs its stain and clear coat kept up.
• Touch-up paint: C.H.I. dealers can provide touch-up paint for every standard color and touch-up kits for Accents Woodtones; ask us for the right one. C.H.I. also publishes Sherwin-Williams paint formulas for its standard colors.
