An estimate was that in 2003, the market for home-maintenance and repair spending was up 14% from 2001 to 2003.[12] Another estimate was that the market in the United States was $126 billion and was increasing by about 4% annually.[10] American homes are aging; one estimate was that in 2007, more than half of all homes are older than 25 years.[12] And, as populations worldwide tend to become older, on average, and since increasingly elderly people will be less inclined and able to maintain their homes, it is likely that demand for handyman services will grow.[original research?][citation needed]

How to DIY it: This job can be messy, so protect nearby surfaces by covering them with plastic or cardboard. Spray the springs with garage door lubricant (about 
$7 at home centers). Don’t use oil, grease, or other lubricants. They may be cheaper, or you may have them on hand already, but they won’t work as well and tend to pick up dust and grit—just what you don’t want on moving parts.
