Wooden gutters are less common than vinyl or aluminium gutters, although they are installed in a similar way and can be very aesthetically pleasing on your house. They are also very strong compared to the other types. Unlike vinyl or aluminium, though, wooden gutters require a great deal of maintenance, as they carry less water than metal or aluminium because their surface is rough. Keeping wooden gutters in proper working order requires a lot of work and maintenance, but can be accomplished by following a few simple steps.
Climb up a ladder and clean out the leaves and other debris in your wooden gutters, using a gutter scooper and throwing all of the debris aside. Toss the larger twigs and leaves aside by hand. Move the ladder around the entire length of the house and remove all the debris inside the gutters.
Pull off all chipped pieces of wood and sand down the gutters with medium-grade sandpaper. Go over every square-inch of the gutters, beginning at one end of the house and working toward the other. Sand in a smooth, circular motion over the entire area until the gutters are smooth throughout.
Seal your wooden gutters with linseed oil. Open up a can of oil and dip a paint brush into the can. Brush the oil over all sides of the gutter, beginning at either end of the house. Continue down the side until all the gutters are covered with the linseed oil.
Wait 15 minutes for the first coat to dry and add a second coat in the same manner. Allow the second coat 15 minutes to dry and inspect the gutter. Verify it is sealed properly and every square inch is covered with the oil.
Always seal your gutters on a day when it is not going to rain. Gutters should be sealed with linseed oil every year for best results and cleaned out on a monthly basis.
Always be careful when working on a ladder. Ensure it is on steady ground when in use.
