Prices for Basic Interior Flush Doors
Interior flush doors are by nature simple and practical. With their smooth, unadorned surfaces, most interior flush doors are economical and affordable options. In general, interior flush doors cost about $20 to $70 for the slab door. However, nicer models will cost more. For instance, interior flush doors constructed with hardwoods are on the more expensive end of the spectrum, costing at least $40 to $50. Hardboard doors are much cheaper, generally costing about $20 to $30. For pre-hung interior flush doors, expect to pay about $60 to $100, depending on the quality of the door’s material.
Often, homeowners hire contractors and professionals to install their doors. This is a great decision, as professionals will get the job done right and leave you free to go about your day without fiddling with knobs and screws and hinges. If you hire a professional, expect to tack on an additional $100 to $200 per door.
Prices for Material and Hardware
Interior flush doors won’t do you any good without hardware, so it’s important to estimate those prices as well. Every door needs a door knob, for instance, and you can expect to spend $10 to $100 on a knob, depending on the quality and material used. Keyed levers, however, can cost as much as $150. Door hinges are also necessary components, and luckily they’re cheap, with the vast majority of hinges costing between $10 and $30. Stains, paints, and other finishes generally have a wide range of prices, but you can assume that most stains will cost between $10 and $20, while most paints will cost $10 to $50.
Prices for Maintenance and Repairs
Any door requires maintenance and repairs, and interior flush doors are no exception. Interior doors take much less of a beating than exterior doors and so, more often than not, the only maintenance or repair you’ll need to worry about will be replacing hinges or knobs, or applying a fresh coat of finish. These repairs are cheap, costing about $10 to $50. However, perhaps your wood interior flush doors have begun to rot, or maybe the surface is dented or scratched. In these cases, some more extensive repairs might be required, so it’s helpful to remember that the average cost of repairing an interior wood door is about $150.
