Gutters do one job: move water off your roof and away from your foundation. When they're sized wrong, hung poorly, or clogged, that water ends up in your crawl space, behind your fascia, or eroding the beds along your driveway instead. In and around McDonough, where summer downpours can dump an inch of rain in under an hour, undersized or leaky gutters show their weaknesses fast. This category covers 24 local businesses that install new gutter systems, replace old ones, and handle repairs like reattaching sagging sections, resealing corner joints, and fixing downspouts that dump water in the wrong place.
What the work actually involves
A standard job starts with measuring your roofline and calculating how much water your roof sheds per hour, which determines gutter size (5-inch K-style is typical for most houses; larger homes or steep roofs often need 6-inch). Most crews in this area run seamless aluminum gutters, formed on-site from coil stock with a portable machine, which cuts down on the leaky seams you get with sectional gutters. Beyond the gutters themselves, a full install includes fascia boards checked for rot, hangers spaced properly (every 24 to 36 inches, tighter in snow-load areas), downspouts sized and placed to carry water at least 5 feet from the foundation, and often gutter guards to cut down on leaf buildup from the oak and pine cover common in this area. Repairs run smaller: re-pitching a section that's holding water, replacing a crushed downspout, resealing miters, or patching holes from ice or a fallen branch.
What to check before you hire
Ask whether the crew forms seamless gutters on-site or installs pre-cut sections, since seams are the most common failure point. Check that the estimate specifies gutter gauge (thicker aluminum resists dents and ladder damage better) and hanger type, not just linear footage and a price. Get clarity on how fascia repair is billed if rot turns up once the old gutters come down, since that's the most common source of change orders. And ask about warranty coverage on both material and labor separately, since a lot of complaints in this trade trace back to installation error rather than product failure.
