Knowing the type of door or doors that need repairing helps your service professional bring the right tools for the job. Every door type has different characteristics. For instance, exterior doors are heavier and generally have more hardware. Sliding doors usually present track repair problems. If a door is painted or stained, there's a chance that the door repair may remove some of the original paint or stain. Having matching paint or stain on hand could save you some money and hassle in advance.
Repair a Door
Some door repairs are cheap projects that don't necessitate purchasing a new door. Wood can shrink, swell, or bow over time, causing the door to stick or an uncomfortable draft into your home. Wood doors can be sanded down to prevent the bottom of the door from catching. Door extenders can lengthen doors and when combined with new weatherstripping will eliminate your draft.
Metal and other types of doors may also end up sticking and be in need of a quick door repair. This usually has nothing to do with the door. Something has probably gone wrong with the attachment to the door jamb. The hinges may need to be tightened or the mortar hinges may need to be deepened to allow for proper door clearance.
Repair Door with a Replacement Door
Most doors are designed to look like wood. Materials such as steel and fiberglass can simulate the look of wood, plus they are more affordable, have a greater insulation value, and require far less maintenance.
All-wood doors are made from softwoods or hardwoods, which are more durable and elegant. Fiberglass-composite doors, made from a core of rigid insulation clad with a fiber-reinforced polymer, are often embossed with artificial wood grain so they look like wood.
Steel doors, made of heavy-gauge, galvanized steel over a core of rigid foam, are strong but look less like wood. Their surfaces usually are coated with polymer or vinyl and are wood-grain embossed. You can also buy doors that consist of veneer applied over solid wood, or veneer applied over a hollow core.
Energy-Efficient Doors
If you must replace your door's windows and/or the door itself, here are some tips to keep in mind. Keeping with today's concerns for saving energy, windows may be standard single-glazed, dual-glazed or even triple-glazed. "R-values" measure heat loss through glass: the higher the R-value, the higher the glazing's resistance to energy loss. By increasing a window's R value from 2 to 4, you can cut energy loss by 50 percent.
Low-E glass has a virtually invisible metallic coating that reflects heat and protects carpets and furnishings from fading by reducing damaging ultraviolet rays from the sun. Even more efficient insulating windows have Argon gas, a natural, colorless, non-toxic gas that is sealed between glass panes. Insulating Low-E glass filled with Argon gas has about twice the insulating qualities of standard dual glazing. Solar bronze and solar gray tinted glass help keep out unwanted heat and ultraviolet rays. If there is a possibility of ultraviolet (UV) damage to floors, rugs and furniture, consider choosing a glazing that resists UV rays.
