Matching Services - New Doors, Existing Frame/Jamb

Front Range Lumber provides a service whereby we use your existing door as a pattern to machine your new door. If the old door fits well and the existing door frame and trim is in good shape, this is a great way to freshen up your home and update the doors. After we complete our work, you job should be limited to painting or staining the door and sliding the hinge pin back in. If you experience any trouble here, slightly tap the hinges until they mate properly.

Custom Work

Our shop can perform a variety of work related to doors, including:

  • Constructing custom wood screen doors
  • Rescreening
  • Repairs
  • Cutting a little off the bottoms of existing doors to accommodate new flooring or carpet

Types/Styles

There are many types and styles of doors available. The four main material categories used are:

  • Pre-primed hardboard
  • Wood
  • Steel
  • Fiberglass.

All are available in a wide variety of sizes and in the case of wood, many species. Ask us for catalogs or consult one of our salespeople for more information.

Pocket Doors

Pocket doors can be an excellent alternative to a regular swinging door. For rooms like bathrooms, closets, and hallway areas, a swinging door may take up too much area to open and close. A pocket door slides into a recess in the wall, allow full use of the wall space on both side on the door. Special pocket door hardware is available for latching and privacy (for bathroom) styles. The hardware is available in all normal finishes to match other hardware used in your home. Premade pocket frames are readily available; we suggest the use of these as opposed to attempting to construct your own. After installation, drywall is put over the cage just as on a normal stud wall. We strongly recommend the use of at least a “heavy-duty” gauge of track and rollers regardless of the door type used. This hardware is beefier and stands up to use far better than “standard” track and hardware. Pocket frames also come in a box – this version requires much more assembly on the job.

Pocket doors normally require a rough opening of double the door width plus 2” and 7’0” in height.

Rough Openings

The “rough” opening or framing hole left to accommodate a prehung wood, steel or fiberglass door should be the raw door size PLUS:

  • On interior units: 2” in width, 2” in height
  • On double interior units: 2-1/2” in width, 2” in height
  • On Exterior units: 2” in width, up to 3” in height
  • ALL should be verified before construction**.

Common Mistakes

Doors incur many of the mistakes in ordering any product we handle. It is easy to mis-oder doors – it’s all in the details. The mistakes typically fall into two categories: sizes and handing (swing).

SIZING: Most errors here occur through mistaking inches vs. feet vs. slang. For example a 2-0 door is a 24” or 2’ door. The MOST common mistake is the size 2-4, which should be a 2’4” door or 28”, but that commonly customers will be thinking 24” only. The best way to avoid any issue here is to identify the door size in inches.

HANDING:  Doors generally swing INTO the room. When it comes to outswinging doors, a picture is worth a thousand words:

Installation

  • After installing any new door, be sure to seal ALL surfaces – this includes the two side edges, top and bottom. Not totally sealing a door may create issues which will not be covered under warranty.
  • On prehung units, the key is to install the unit perfectly level and plumb – both the door and the frame.

Warranty Issues

Refer to the individual manufacturer’s information regarding warranty details. There is probably no other category in the construction area where more corners can be cut and the price changes accordingly. This translates into that you get exactly what you pay for.
