You can start your own business, cleaning awnings and gutters. You will need a pressure washer to perform this job. Austin Gutter Association is one of the authority sites on this topic. You can buy a new one, or you can sometimes find a good deal on used ones, if you look at places like Craigslist, or your local newspaper classifieds, you can usually get a decent deal on a used one as well if you look around, you can also rent one, until you can afford to buy one. You can target businesses and homes with awnings, and contract to clean them one time, or on a scheduled basis. You can also offer gutter cleaning, and most all homes, have rain gutters, that eventually seem to get clogged up with all kinds of leaves and debris.
If you still don’t have a pressure washer, you could always rent one, when you land a big job. They have “U” shaped cleaning tubes that make it easy to pressure wash, and clean out the gutter systems along the roofs of houses, right from the ground, using wand extensions, and the job will be quick, and less chance of falling off of the roof!
You should make up some signs for your vehicle, and have some business cards made up too. You should drive around your neighborhood sometimes, and look at all the houses, that have large trees hanging over them, they will be good candidates! It helps to remind the customer, that if his rain gutters get clogged up, his foundation could get ruined, if the water does not properly drain away from the foundation, and the water could puddle up, and over time, to some serious damage to his house. This usually motivates the customer into having it done, right away!
You could also send out some fliers, to all the painters, roofers, tree maintenance companies, etc, and let them know you are in business! They will see more gutters, than other services, so offer them some sort of deal, if they send you any customers.
