Gutters have the important job of collecting and directing rain water to where it can drain without harming your landscape or home.Ignore a leak and you could get some pretty unwelcome damage.Itcould be immediate, like waterseepingin your basement. Or itcouldtake a slow toll, ruining paint and even rotting wood. Fortunately, fixing a leaky gutter isn’t difficult.Take action withone of these easy fixes.
Leaking Gutter Joints
Step 1: Clean Out Debris
Leaks can develop at gutter endcaps and seams. When determining how to fix a leaking gutter joint, first scoop or scrape out any debris that may have accumulated around the endcap or seam.
Step 2: Scrub with Plastic Scouring Pad
Scrub the area around the joint with a plastic scouring pad. Then wipe down the area with rubbing alcohol or denatured alcohol.
Step 3: Apply Sealant
Apply DAP Ultra Clear Flexible All Purpose Waterproof Sealant to the inside of the gutter at the endcap joint or along a seam. DAP Ultra Clear provides a 100% waterproof and weatherproof seal. It can be applied to wet or damp surfaces, is rain-ready immediately and stays permanently flexible to withstand temperature extremes without cracking.
Leaks Behind the Gutter
If there’s a gap between the gutter and fascia, water can run behind the gutter and damage the fascia. Look for gapsbig or small between the gutter and the fascia. If you see any, apply a bead of DAP Ultra Clear to fill them.
Leaks from a Sagging Gutter
A sagging gutter can result in water not draining properly. To repair it, push the gutter back into position, keeping in mind you also want to maintain a slope toward a downspout (½ inch for every 10 feet). Secure the gutter by installing gutter hanger brackets at least every 2 feet. The brackets fit inside the gutter. To use, drill holes for the brackets, going through the gutter apron if it extends down into the gutter, and into the fascia. Place each bracket under the front lip of the gutter and attach. Make sure you purchase brackets with the screws built in (the type shown here). They cost more but are easier to install.Remember to fill any old screw holes with Ultra Clear to prevent future leaks.
Bonus Tip:The large screws included with the hangers may be a little tricky to get started, especially when you’re drilling through steel gutters and flashing. Spin the screws at high speed at first, without applying much pressure, until the screw tip bites into the metal. Then lean on the drill and drive them into the fascia.
