Sagging gutters: what a fix costs on a real house

A sagging gutter costs $200 to $500 to put right on a typical run: $200 to $450 to re-hang, $200 to $500 to re-pitch, and $6 to $12 per linear foot if the fascia behind the hangers has rotted. Replacement, at $7 to $15 per foot, is $1,400 to $3,000 on a 200-foot house. The repair is almost always the better buy, and the arithmetic below shows where that stops being true.

What you are paying for

Three things: labour to empty and re-set the run, hardware to replace the failed hangers, and carpentry if the board the hangers screw into has lost its strength. The gutter metal itself is rarely part of the invoice, because a sag does not consume aluminium.

That is why a re-hang is a half-day job rather than a materials purchase. On a 30-foot span, ten hidden hangers at $8 to $15 each is $80 to $150, and two to three hours of labour at $70 to $100 is $140 to $300. Total: $220 to $450.

The price by job type

The fascia row is the one that surprises people. At $6 to $12 per foot, a 60-foot run is 60 × $6 = $360 at the low end and 60 × $12 = $720 at the high end, and the re-hang is billed on top because the gutter has to come off and go back on.

Per-foot arithmetic by house size

The job price barely moves with length because the labour is dominated by setup and the number of spans that have actually failed, not by the total run. The fascia column assumes the whole run needs board, which is the worst case; most jobs need it over 20 to 40 feet.

Repair or replace, in numbers

Repair wins while the metal is sound. On a 200-foot house, $200 to $500 is 14 to 36 percent of a $1,400 replacement and buys another decade on a run that is otherwise intact.

Replacement wins when the trough is creased at the hanger points, when the fasteners have torn through the lip in several places, or when more than a third of the hangers have failed. Those are signs that the remaining metal and the remaining board are the same age as the failures, and re-hanging moves the problem 10 feet along.

There is a middle case worth pricing: replacing one 10-foot section at $150 to $400 rather than the whole run. It is the right answer when a single length has lost its shape and the rest of the run holds its line.

Five steps to price your own repair

1. Measure the run that has actually dropped, not the whole gutter.
2. Count the hanger positions along that run. Ten hangers at $8 to $15 is $80 to $150 in hardware.
3. Probe the wood at each hanger with a screwdriver. Soft wood adds $6 to $12 per foot.
4. Decide whether the fall has to change. If water stands after rain, it does, and that is the $200 to $500 line.
5. Multiply any replacement length by $7 to $15 per foot before comparing it with the repair total.

The output of those five steps is usually a number between $200 and $700. If a quote lands far above it, ask which line the contractor is seeing that you are not, because the difference is nearly always fascia or access.

The hidden lines on a quote

• Guard removal and refitting. If a screen or mesh is fitted, it comes off and goes back on, and that is labour.
• Downspout adjustment. A re-pitch changes where the outlet sits, and the pipe may need a new elbow.
• Sealant and touch-up. New fasteners through old metal need sealing, and the paint line rarely matches.
• Disposal. Old gutter and rotted board have to leave the site.
• Access. A two-storey wall or a roof under 4/12 pitch adds setup time and sometimes a lift.

Ask which of these are included before comparing two totals. A $250 quote that excludes fascia work and a $600 quote that includes it are not describing the same job.

When the guard should wait

Fitting a guard to a sagging run is money spent on the wrong layer. Mesh systems cost $1,800 to $4,500, and the panels fasten to the gutter, so they follow whatever line the gutter has. A run that sags 2 inches will hold a mesh panel that sags 2 inches, and the low point still collects water.

Fix the support first, then buy the guard if debris is the remaining issue. The order is priced in sagging gutters: repair options and the guard side is in gutter guard cost. If the run has gone too far, gutter replacement cost has the per-foot breakdown by material.

The short version

Budget $200 to $500 for a re-hang or re-pitch, and add $6 to $12 per foot if the fascia is soft. That is the whole repair on a sound gutter. Replacement only makes sense when the metal itself has failed, and at $1,400 to $3,000 for a 200-foot house it should be a deliberate decision rather than the first quote accepted.
