On jobs where you don't want to be held up, like felling trees away from home, consider having two chainsaws available. Make sure both are in working order before starting. Then if one needs its chain sharpened, you can use the second one to finish the job. By using two saws any maintenance can be done between, rather than during, the project. Also consider doubling up on other small tools, like pliers and screwdrivers, so they can be kept in different areas to cut down on running from house to garage.
Many utilities offer incentives to homeowners who make improvements that save energy. Contact your utility company to determine if you’re eligible for a low-interest loan or discount for replacing your windows and doors. Ask about energy-efficient insulating features such as argon gas between the panes of glass and a Low-E coating.
