Gutter Repair & Downspout Work on San Juan Island

If your gutters are simply full of fir needles, that is gutter cleaning and moss removal and it is an annual chore. This page is the hardware: the run that has dropped an inch in the middle and now holds standing water, the spikes you can pull out with two fingers, the end cap that drips a rust stain down the corner board, the downspout that discharges four feet from the crawlspace vent. None of that is fixed by cleaning it out again.

The single most common failure I find on island houses is the spike and ferrule. It is what came standard on anything hung before roughly the mid-nineties: a seven-inch nail driven through the front lip of the gutter, through a spacer tube, and into the fascia. It works until the fascia softens or the nail backs out from thermal movement, and then the run sags at that point, water pools, the pool gets heavier, and the next spike goes. Out here there is a second driver. Electroplated and plain galvanized fasteners within sight of salt water corrode from the head down, and once the head is gone the spike is a smooth pin sitting in a wet hole. I replace them with hidden hangers screwed through the back wall of the trough into solid fascia, spaced tighter than the twenty-four inches you would use in a dry climate, because our gutters carry needle load and standing water in November, not snow.

Slope is the part people do not think about. A gutter is supposed to fall roughly a quarter inch every ten feet toward the outlet, and it is startling how many island runs are dead level or fall the wrong way because they were hung to the roof line rather than to a chalk line. A level gutter grows mosquito larvae in July and algae year round, and it will hold enough water to bend itself. When I re-hang a run I string it, set the fall to the actual outlet, and add a second outlet and downspout if one drain is trying to carry a forty-foot run off a steep roof, which it usually cannot in a hard November rain.

Seams and end caps are the other repair. Sectional aluminum gutter is joined with lapped seams and sealed, and that sealant has a service life measured in years, not decades. Once it fails the joint weeps behind the gutter and onto the fascia, which is how a five-dollar problem becomes a fascia board and then a rafter tail. I clean the joint back to bare metal, dry it, and reseal with a gutter and flashing sealant that stays flexible instead of the hardware-store silicone that lets go the first cold snap. Where a section is bent, corroded through, or has been patched three times, I replace the section and match the profile. Browne’s in Friday Harbor carries the common K-style sizes and stock white and brown finishes.

Then there is where the water goes, which matters more than any of the rest of it. A thousand square feet of roof sheds a lot of water in a Northwest winter, and a downspout that ends in an elbow at the base of the wall is putting all of it into the soil against your foundation and crawlspace. That is the origin story of most of the damp crawlspaces I get called into. The fix is usually cheap: proper elbows and a boot at the bottom, a splash block or a solid extension carrying discharge a good distance out, and if the grade will not cooperate, a buried solid pipe running to a place where it can daylight. If the water needs to go somewhere the yard has not got, that becomes yard drainage and runoff work and I will quote it that way rather than pretend a splash block solved it.

I work from ladders and I work from the ground. What I do not do is roofing. If the water is getting in above the gutter line, at a valley, at a chimney, or under the drip edge, that is roof work and roof-level flashing, and I do not touch either. I will photograph what I see from the ladder, tell you plainly what a roofer needs to look at, and give you the pictures to send them. Fascia and trim I can repair, and often the fascia behind a failed gutter is exactly what needs attention before anything new gets screwed to it. There is no point hanging good hardware on wood that will not hold a screw, and I will not do it.

On gutter guards my opinion has not changed: under firs and cedars they still clog, they just clog somewhere harder to reach. Where they genuinely earn their keep is a two-story run over a hard-to-ladder pitch or a house nobody visits between October and May, and in those cases I will install them and tell you honestly that they reduce the frequency of cleaning rather than eliminate it. I would rather sell you two good hangers and a longer downspout extension than a guard system that changes your maintenance schedule but not your maintenance.

Timing: the right season for this is late summer through early fall, alongside the annual cleaning, so the repairs are done before the first real atmospheric river shows up and finds every weak seam at once. The other honest window is right after a storm, because a hard southwesterly is the best diagnostic tool there is. If you can get out under an active downpour and photograph where water is spilling over, running behind, or pouring out of a joint, that ten seconds of video tells me more than an hour on a dry ladder.
