Howell Gutters handles gutter repair in Howell, NJ, with 20+ years of fixing leaks, sags and blocked downspouts on every kind of system, serving surrounding cities including Ramtown, Freehold Township, Wall, West Freehold and Vista Center. Most gutter problems come down to a handful of causes, and the fix is usually quicker and less expensive than an owner expects once the real cause is found.
We start by finding out why the gutter is failing rather than treating the symptom. A drip at a corner might be a failed seal, but it might also be a gutter pitched toward that corner with no outlet nearby. A gutter pulling off the house might need new hangers, or it might be hanging from rotted fascia that has to be replaced first. We show you what we find before we fix it.
Every repair comes with before-and-after photos, and repair work is priced on its own line, apart from any new gutter, because New Jersey taxes repairs and new installations differently. If a repair is not worth doing, we say so and explain why.
Gutter Leaks We Repair

Leaking Seams and Corner Miters
Sectional gutters have a joint every ten feet or so, and every seamless gutter has corner miters where two runs meet. When the sealant in those joints dries and cracks, water drips through onto walkways and down the siding. We clean the joint to bare metal and reseal it with tripolymer gutter sealant, which stays flexible through hot summers and freezing winters.
If a miter has split, corroded or been crushed, sealant alone will not hold. We replace it with a new box, strip or bay miter matched to the gutter’s profile, so the corner is rebuilt rather than patched.
End Caps and Outlets
End caps and downspout outlets are the other common leak points. A cap can work loose as the gutter expands and contracts, and an outlet can separate from the trough when a downspout is pulled or bumped. We reseat and reseal caps, and where an outlet is torn or undersized, we cut in a new one, often a wide-flange outlet that carries more water into the downspout.
Holes and Corrosion in the Trough
Small holes from rust on older steel gutters, or punctures from a ladder or falling branch, can be patched with matching metal and sealant when the rest of the gutter is sound. When corrosion has spread along the length of a steel gutter, patches stop holding and we recommend replacing that run with seamless aluminum.
A single damaged run can usually be replaced on its own, formed on site to the length of that eave, without touching the rest of the house. We match the profile and color as closely as possible, so a repaired rear gutter does not look out of place beside the original runs on the front.
Sagging, Loose and Mis-Pitched Gutters
Spikes Backing Out of the Fascia
Many older gutters were hung with spikes driven through ferrules into the fascia. Over years of wood swelling and shrinking, the spikes work loose and the gutter starts to sag between them. We replace them with hidden hangers screwed into the fascia at close spacing, which hold the gutter’s shape and do not back out the way spikes do.
Resetting the Pitch
A gutter has to fall steadily toward its outlet, and a run that has sagged or was hung level will hold water. Standing water adds weight, speeds up corrosion and gives mosquitoes a place to breed, which is why Monmouth County Mosquito Control advises keeping gutters properly pitched. We snap a new line and reset the hangers along it so water moves to the downspout.
Resetting the pitch on an existing run is often all that is needed to stop water from spilling over the low spot. Where the run is too long to fall properly toward one outlet, we may suggest adding a second downspout at the other end.
Rotted Fascia Behind the Gutter
If hangers will not hold, the fascia behind them is often soft. We probe it, show you the rotted section, and replace it before the gutter is rehung, so the repair does not fail again in a season. On houses built before 1978, painted fascia and trim fall under the EPA Renovation, Repair and Painting rule (40 CFR 745), which sets how painted surfaces may be disturbed.
Overflow and Water Behind the Gutter
Water Running Down Behind the Gutter
When water runs down the wall behind a gutter rather than into it, the roof edge is usually sending water past the back of the trough. A gutter apron or drip edge slipped under the shingles bridges that gap, and lowering a gutter that hangs too far below the roof edge can help as well. Left alone, that water rots the fascia and stains the siding.
Kickout Flashing at Roof-to-Wall Joints
Where a roof slope ends against a sidewall, water running down the step flashing can pour straight onto the siding beside the gutter end. A kickout flashing turns that water into the gutter. We add one when it is missing, because the damage it prevents shows up as rot and staining in the wall below.
The usual sign is a dark streak or soft siding just below where a lower roof meets a wall, often near a garage or a porch roof. If you have one, mention it when you call; it is one of the few gutter-related problems where the damage often shows up inside the wall before anyone notices it outside.
Gutters That Overflow in Heavy Rain
Overflow is not always a clog. A downspout too small for the roof area it serves, too few downspouts on a long run, or an undersized gutter can all spill over in a downpour even when perfectly clean. We look at the roof area feeding the overflowing section and fix the capacity problem, whether that means a larger 3x4 downspout, an added outlet or, in some cases, a wider gutter on that run.
Downspout and Drainage Repairs
Crushed, Disconnected and Clogged Downspouts
Downspouts get crushed by lawn equipment, knocked loose by ladders, and packed with needles at the elbows. We straighten or replace damaged sections, reconnect them to the outlet with properly fitted A and B elbows, and fasten them to the wall so they stay put. Clogged elbows are cleared and flushed before we leave.
Underground Downspout Lines Backing Up
If water bubbles out at the base of a downspout that feeds a buried pipe, the line is blocked, crushed or has no working outlet. We flush it, check the far end, and dig at the problem spot if needed. A line that cannot be saved is replaced, often ending at a pop-up drainage emitter in a low part of the yard.
In Howell, roof water must never be routed into the sanitary sewer; Township Code Section 252-21 makes any drainage connection to the sewer a violation. When we repair or reroute a line, the estimate states where that downspout will discharge.
Moving Water Away From the Foundation
A downspout emptying against the house is one of the most common reasons for a wet basement after rain. The New Jersey edition of the 2021 International Residential Code calls for the ground to fall 6 inches within the first 10 feet from the foundation (R401.3), and an extension or emitter helps the downspout use that slope. We often add one as part of a repair visit.
