Clean the dryer exhaust
A clogged vent is a potential fire hazard and a drain on your dryer’s efficiency. Make sure the exhaust is coming out while the dryer is running. If you don’t notice much exhaust, you may have a blockage, which is best determined and repaired by a professional. Vacuuming the vent will also help the dryer’s performance.
Clean and repair the deck
A thorough washing may be all it needs, but if your deck has loose boards, cracks or decay, it needs more work. If that’s the case, pressure wash it first. Always test for decay, especially in areas that seem to stay damp. If the wood is soft and spongy, or doesn’t splinter when poked with a screwdriver, your deck may not be safe to use. Also, look for small holes, which can be a sign of insects. If the deck coating has worn away, apply a waterproofing coating after cleaning.

Clean out gutters and window wells
Leaves, petals and seeds can accumulate in your gutters and window wells in the summer. Clear the debris to keep rain water draining properly and away from your home’s foundation. Also, make sure an animal hasn’t turned your window well into its home.

Inspect your roof
A very simple and easy way to inspect your roof without risking your safety: use binoculars. If you only need a few shingles replaced, a handyman may be able to replace them for a nominal charge. For extensive damage, you should contact a professional roofer.

Caulk the cracks
Check for gaps around windows and doors and reapply caulk to prevent leaks. Also, add weather stripping to doors. You’ll help your air conditioning system run more efficiently and will save money.
