Drip begins at one visible joint
The joint is a reasonable inspection point, but upstream overflow and standing water still need checking.
Notice next: Record the start point and whether the trough is also spilling over.

Leaking gutter joint
What does a leak at a gutter seam or corner mean?
A drip at a seam can involve a joint, fastener, sealant, corrosion, movement or water standing in a misaligned section. Water that appears at the seam can also be overflow arriving from another point. The visible drip is an inspection location, not proof that resealing alone will be durable.
Record whether the leak occurs only in heavy rain, whether water is standing after rain, and whether the joint is separated, deformed or attached to damaged fascia. A written repair scope should say what condition was found, how surrounding material and alignment were checked, and whether repair or section replacement is being proposed.
Put safety before diagnosisObserve from the ground; wet ladders, sharp metal edges and loose gutter sections make close DIY inspection hazardous.

U.S. national guidance
What changes after you choose a location?
Choose a state to make the geographic boundary explicit.
A ZIP helps identify possible gutter service areas and drainage jurisdictions, but it does not prove jurisdiction, address-level coverage or an available gutter or drainage professional.

Which situation best matches the home?
Leak appears at a corner
Corners combine joints and changing flow direction and may need a broader alignment check.
Notice next: Note separation, deformation and nearby staining without handling the joint.
The seam leaked again after prior work
Recurring leakage may reflect movement, preparation, material condition or unresolved slope and flow.
Notice next: Collect the prior scope and dates for the inspector.
Safe observation
What should you record before the call?
A short, factual description helps the next professional choose the right first inspection without treating a symptom as proof.
A dripping joint does not establish the gutter material's remaining life, concealed fascia condition or the correct repair product and method.
What to record
- Seam or corner location and whether overflow also occurs.
- Rain conditions and whether water remains afterward.
- Visible gaps, corrosion, deformation, fastener or sealant changes.
- Fascia, soffit, wall and ground staining near the joint.
Stop and get appropriate help
- The gutter or fascia is loose, sagging or at risk of falling.
- Water is entering electrical equipment or causing rapid interior damage.
- Safe inspection requires roof access or contact with sharp, corroded material.
Short answers
Questions people ask before the call
Can I just add more sealant?
Not until the joint, surface condition, movement, alignment and water path are understood; a surface patch may not address them.
Does one leaking seam require full replacement?
No. Extent, material condition, attachment, alignment and repairability must be inspected.
Why does the seam leak only in heavy rain?
Higher flow can expose overflow, capacity or alignment conditions, but the pattern does not prove which one.
