Maintaining gutters is the most important thing you can do to prevent water damage to your home. Gutters are designed to do one thing — channel water away from the foundation — and they’re critical to protecting the structural integrity of your house. But in order for gutters to do their job properly, they have to be kept in shape and free of clogs, holes, and sags.
This is the most common problem of all. Left untended, gutters and downspouts get so clogged with debris that they’re rendered useless. The excess weight of leaves, twigs, and standing water can also make them sag and pull away from the fascia.
Clean them at least once a year, and twice a year if you have a lot of trees nearby. Gary Mindlin, managing partner of New York City-based Top Hat Home Services, schedules gutter maintenance four times a year, with additional checks after big storms.
You can clean your own gutters if you’re comfortable on a ladder, don’t mind getting wet and dirty, and don’t have an extremely tall house. After you’ve cleared the muck, flush them with a garden hose to make sure they’re flowing properly. If you’d prefer, you can hire someone to do the job for you for between $50 and $250, depending on the size of your house.
Sagging gutters and gutters pulling away from the house
This is usually a problem with the hangers, the hardware that secures the gutters to the fascia. They might have deteriorated over time, the fasteners may have backed out of the wood, or they’re spaced too far apart to support the weight of full gutters. The cost to fix it yourself is cheap; hangers generally cost $10 or less apiece, and the fasteners run about $1 each.
Leaks and holes
Leaky gutter joints can be sealed by caulking the joint from the inside with gutter sealant, says John Eggenberger, vice president of training and corporate development for the Mr. Handyman franchise of home repair companies. A tube costs about $5. Very small holes can be filled with gutter sealant. Larger holes will require a patch. If you can’t find a gutter patching kit at the hardware store, you can make a patch from metal flashing.
Improperly pitched gutters
Gutters need to be pitched toward the downspouts for the water to flow properly. You want at least a quarter inch of slope for every 10 feet. Get on a ladder after a rainstorm and look in the gutter; if there’s standing water, it’s not pitched properly.
Downspouts draining too close to the foundation
Downspouts need to extend several feet from the house, or they’ll dump right into the basement. Gutter extensions attached to the bottom of the downspout will discharge water well beyond the foundation. They’re inexpensive and easy to install. “I like the downspout material extended four or five feet and screwed on,” says Reggie Marston, president of Residential Equity Management Home Inspections in Springfield, Va. Cost: less than $20 per downspout.
