Buy wood doors by the book

The budget book, that is. Investments in real estate properties that see a frequent change of tenants require commercial wood doors that are sturdy, yet reasonably priced. Also consider whether your wood door needs to be soundproof.

I recommend: CraftMaster interior wood doors are available in several styles, and the company also offers basic paneled doors and pine. They make excellent replacement doors for apartments. Interior Doors Direct also offers several styles of interior wood doors, but the basic paneled doors are good replacements.

Replace the ordinary with extraordinary custom wood doors

Make your office space special with custom wood doors by specifying door design, wood type and dimensions, as well as choosing veneer and engineered core components or laminated lumber. Add interest with Dutch doors, also known as stable doors. The top half of the door opens while the bottom remains closed, enabling the person in the office to see who is outside the door while maintaining privacy of the workspace. Also consider French doors, which normally consist of double doors with eight to 10 panels of glass in each door, though the glass design may vary.

I recommend: Contact Simpson Door Co. for orders of custom wood doors. Algoma Hardwoods is among the wood door manufacturers producing wood doors that emphasize the beauty of wood grain patterns.

Go for unique interior wood doors

Ornate Victorian-style wood exterior entry doors, panel doors with glass of varying texture and color and arched doors are only a few styles offered by wood door manufacturers to give that "Wow!" to rental properties or the office. For a breathtaking effect, go for a hand-carved wooden door with scenes of nature and animals.

I recommend: YesterYear's Vintage Doors handcrafts each door from 100% furniture-grade solid wood. Check out their interior wood doors and  exterior wood doors. For a truly exotic look, go to the Richard Cornelius website to see his hand-carved wooden doors.
