Rain gutters direct the flow of rainwater away from a building's foundation. This reduces water damage around the foundation and keeps water from collecting in low spots of sidewalks and outdoor living areas. The slip joint connectors that secure lengths of gutter are a common leak point if the connectors are installed incorrectly. Correctly sealing a slip joint requires an adequate sealant and properly seating both lengths of gutter in the joint. Failing to make a proper slip joint connection can lead to costly repairs to your home.
Cut a 45-degree opening on the nozzle of a silicone caulk tube by inserting the end of the nozzle in the hole located behind the handle of a drop-in caulking gun and squeezing the handle. Slide the wire — located near the front of the caulking gun — into the cut opening.
Pull the front edge of the slip joint connector away from the connector body to release the inner clamp. Coat the inside of the connector bottom with silicone caulk.
Set the ends of two lengths of gutter in the slip connector. Push the inner clamp toward the ends of the gutters until the inner clamp "snaps" in the upper flange of the slip joint.
Allow the silicone to cure for four to six hours before installing the gutter on the fascia board of your home.
