A dripping seam looks like the simplest problem in guttering — clean it, seal it, done. And sometimes it is. But the same tube of sealant is an honest repair on one house and a six-month bandage on the next, and the difference isn't the sealant. It's the metal underneath.
Why seams fail in Austin
Sealant is the flexible link between two pieces of aluminum, and Central Texas is hard on it from both directions. Summer bakes it brittle on hundred-degree metal; storm loads flex the joint while it's stiff. Add standing water soaking it from above and the sealant loses adhesion years ahead of schedule. The drip at the corner or the end cap is the sealant announcing retirement.
When resealing is a real repair
Three conditions, all required. The metal at the joint is sound — no cracks, no fatigue, no deformation. The joint is stable — hangers tight and slope correct, so the seam isn't flexing with every load of water. And the prep is done right: old sealant fully cut out, metal cleaned to bare and dry, new sealant worked into the joint rather than smeared over the top. Meet all three and a reseal holds for years. That's a legitimate fix, not a compromise.
When it's a bandage
Skip any condition and you're renting a repair. New sealant smeared over old sealant lets go quickly. A seam that flexes because the run sags will crack any sealant you put in it — the slope problem has to be fixed first or the reseal is theater. And a sectional system failing at joint after joint is telling you the sealant era of its life is over; resealing thirty joints one drip at a time costs more than fixing the actual problem.
The straight answer, in writing
At the estimate we tell you which case your gutters are — reseal-worthy, tune-up-first, or past it — and price the honest option. That's the whole model behind the tune-up service, and the assessment is free.
