Most homeowners will face a time when their carpet needs a repair. Perhaps there is a stubborn stain or even a carpet burn that is marring the surface. However, the carpet is generally still in terrific condition and you don't need to replace the entire room. When facing this dilemma, there are a number of choices.
For homeowners who are handy with home repairs, consider trying to fix the carpet yourself. Take out the leftover carpet that was kept just for this purpose and cut out the piece to be replaced with a utility knife, make the cut large enough to get rid of all the damage. Make the lines clean and straight, using a straight metal edge to help guide the knife. Lift out the damaged area and then use it as a guide to cut the replacement piece. Match up the direction of the nap before cutting, put a small amount of glue on the existing padding, insert the replacement and let dry. Once dry, brush the fibers together so that the patch blends. Keep in mind that smaller patches are more likely to reintegrate successfully into the carpet than larger ones.
If you're not comfortable attempting the repair on your own, there are several options for finding professional help. Handymen are service providers who have a wide range of general household repair skills. Look for one that has a positive reputation and is bonded. Handymen are usually the least expensive option, averaging $20 to $25 per hour. Many handymen will also negotiate a fixed fee, based on the scope of the job.
For water and smoke damage there are numerous service companies that specialize in cleaning a home after a flood or fire. They use advanced techniques that clean and deodorize a home after catastrophic events. Cleaning and restoration services are more expensive and generally charge by the job instead of by the hour. They will clean walls, ceilings and other surfaces that may be damaged. Many retail carpet stores will offer this service, though they specialize in carpet patching, stretching and repairs other than cleaning. Prices vary significantly, so shop around.
