Garage Door Roller Replacement: comparing quotes

The figure is the wheel diameter, and it has to match the track. Residential sectional doors run on two-inch track and take a two-inch wheel; commercial doors can run on either two-inch or three-inch track, so the wheel is matched to what is actually installed. Wheel size has little to do with noise, which comes from the wheel material and bearings. The technician measures the track and the existing wheel before ordering so the set fits, since a mismatched wheel either jams in the channel or rattles around in it.

Balance adjustment first

If the door drifts when released at halfway, the spring system needs adjusting before new rollers are fitted so they do not wear early; that adjustment is quoted as its own line.

Weight and construction of the door

A heavy insulated steel or solid wood door needs higher-rated rollers and takes more care to secure and handle than a light single-skin door, which shows in both parts and time.

Hinges that need replacing

Cracked, elongated or rusted hinges found during the inspection are replaced with the correct numbered hinge, each priced as its own item alongside the rollers.
