Drip line under a corner or seam
A stain, mud line, or eroded dirt directly under one spot on the gutter usually means that joint is leaking.

About This Service
What gutter sealing actually looks like
A leaking gutter doesn't have to mean a full replacement. Most leaks show up in the same places every time: the end caps, the mitered corners at each turn, and the seams where two sections meet. A proper cleaning, dry surface, and the right sealant handles the majority of them.
During a cleaning we look at every seam and end cap. When we find a leak, we clean the joint back to metal, let it dry, and lay a bead of exterior-grade gutter sealant. On a normal seam that's a 10-minute fix that adds years to the system.
We're transparent about limits: sealant is the right answer for small seam leaks and pinhole spots. If a gutter is rusted through, badly pitched, or coming loose from the fascia, sealing it is a band-aid — we'll say so and point you toward the right fix.
What You Get
Every gutter sealing job includes
- Inspection of every seam, corner, and end cap
- Cleaning and drying of any joint we seal
- Exterior-grade gutter sealant applied properly (not caulk)
- Photos of each spot we sealed
- Honest recommendation when sealant isn't the right fix
Warning Signs
When to call us out
Any one of these is worth a look. Two or more usually means the problem's been quietly building.
Water on the wall below an end cap
End caps are the most common leak on aluminum gutters — they get bumped, flex, and pull away from the sealant bead.
Rust spot at a seam
Water sitting at a joint slowly corrodes it. Caught early, sealant stops the leak — caught late, that section needs replacement.
Our Process
How the job actually happens
- 1
Clean first
We won't seal a dirty joint. Sealant only bonds to a clean, dry gutter.
- 2
Identify every leak point
We work section by section and mark each spot that needs sealant.
- 3
Proper product, proper bead
We use gutter-specific sealant that stays flexible in Tennessee heat and cold. Silicone-caulk-from-the-hardware-aisle is not the right product.
- 4
Cure & photo
You get a photo of every seam we sealed. Full cure takes 24 hours; we advise avoiding forced water over sealed joints for a day.
Honest Pricing
What this costs
Sealing is quoted per repair, not per house. Small jobs (one or two end caps and a seam) are usually a modest add-on to a cleaning. Larger jobs we quote after we see how many joints are involved.
Sealing extends the life of a working gutter — it isn't a substitute for replacement on a badly damaged or improperly pitched system.
FAQ
Common questions about gutter sealing
How long does gutter sealant last?
+
A properly applied bead on a clean joint usually lasts 5–10 years. Sunlight, thermal cycling, and the movement of the gutter itself all shorten that; a north-facing seam typically lasts longer than a south-facing one.
Can you seal gutters that are already leaking during rain?
+
We can identify them, but sealant needs a dry, clean surface to bond. We'll schedule the actual sealing for a dry day — often the same visit if the sun catches up.
What if my whole gutter run leaks?
+
That usually means the gutter is either misaligned, rusted through, or has failed at the hangers. Sealing every joint doesn't fix any of those, and we'll tell you honestly if replacement is the smarter money.
