How Much to Charge for Gutter Installation: Per Foot Plus Downspouts

Short answer: How much to charge for gutter installation comes from two units, not one. Price the run per linear foot of formed gutter, and price downspouts separately by count and drop height, because a per-foot number hides them. A 168 ft single-story replacement with six downspouts might run 8.5 crew hours and $610 of material. Add overhead, divide by one minus your margin, and only then look at what the price works out to per foot.

The per-foot number is how customers shop and how estimators get hurt. Two houses with identical eave footage can be a one-day job or a two-day job depending on how many downspouts drop, how far off the ground the ladder foot sits, and whether the fascia behind the old gutter is sound. What follows builds the price from the pieces, then converts to a per-foot figure at the end, which is the only order that survives contact with a colonial. The paperwork side is covered in what to include on an invoice.

What unit should a gutter quote actually run on?

Linear feet for the trough. Everything vertical, conditional, or accessory gets its own line.

Line	Unit	Why it is separate
Seamless gutter	Per linear foot of formed run	The one number the customer will compare
Downspouts	Per drop, priced by height	A three-story drop is three times the material and more than three times the time
Miters and end caps	Per piece	Inside and outside corners are labor, not footage
Gutter guards	Per linear foot, own line	Sold and declined independently of the gutter
Tear-off and haul	Per linear foot of old gutter	Skipped entirely on new construction
Fascia repair	Per foot of rotted board, conditional	Discovered after tear-off, never before
Cleaning	Per story and home size, not per foot	A separate service with a separate crew profile

Roll the downspouts into the per-foot rate and you have built a pricing system that overcharges simple ranch houses and loses money on every house with a complicated roofline. That is precisely backwards from how you want to win work.

How do I take the measurements the price depends on?

Walk the house and record four things by elevation, not as one total.

• Eave footage per side, so the coil order and the miter count fall out of it.
• Corner count, split into inside and outside miters.
• Downspout locations and drop heights, measured from gutter to grade plus any offset at the overhang.
• Ladder access per elevation — deck below, bushes, a slope, an air conditioner, a conservatory roof.

Downspout count is a design decision, not a customer preference. The common working rule is one downspout per 30 to 40 feet of run, then checked against drainage area: a 2x3 downspout handles roughly 600 sq ft of roof, a 3x4 roughly double that. On a steep roof in a high-rainfall region, the count goes up and the outlet size goes up with it. Undersizing here produces overflow, callbacks, and a warranty argument you cannot win.

What does an hour of crew time cost me on this trade?

Gutter work is a two-person trade for most of the day, so build the rate around the pair.

Layer	Example calculation	Per crew hour
Lead plus helper, with burden	($26.00 + $18.00) × 1.28 for payroll taxes, comp, and liability	$56.32
Truck, trailer, roll-forming machine, ladders, insurance	$18,200 a year ÷ 1,050 billable crew hours	$17.33
Operating cost		$73.65
Overhead	$31,500 a year — yard, phone, estimating time, marketing, licensing — ÷ 1,050 crew hours	$30.00
Fully loaded cost		$103.65

The machine belongs in that middle line, not in material. A roll former is a capital asset with a payment, a maintenance habit, and a set of drive rollers that wear; spreading it across billable crew hours is what turns “we run seamless” from a marketing line into a costed advantage.

How much material does a linear foot really consume?

More than the coil. Price each component off your last supplier invoice, because aluminum coil moves with commodity pricing and a six-month-old number is a guess.

Component	Consumption rule	Example on 168 ft
Coil, 5” K-style from 11.75” stock	Run length plus 5% for cutoff and machine setup	177 ft at $1.22 = $215.94
Hangers	Every 24”, tightened to 16” in ice and snow country	84 at $1.35 = $113.40
End caps	Per gutter termination	4 at $2.10 = $8.40
Miters	Per inside and outside corner	4 at $12.00 = $48.00
Outlets	One per downspout	6 at $2.40 = $14.40
Downspout stock	Drop height plus offset per location	72 ft at $1.55 = $111.60
Elbows	Two to three per drop	18 at $2.85 = $51.30
Straps and bands	Two per drop, more on tall runs	12 at $1.10 = $13.20
Sealant, screws, rivets	Per job	$34.00
Material total		$610.24

Coil width sets the profile: 11.75” stock forms a 5” K-style, 15” stock forms a 6”. A 6” system with 3x4 downspouts costs more per foot in every one of those lines, so it is a different price, not a $1 upgrade. Old aluminum coming off the house is scrap with a value — a 168 ft tear-off is worth something at the yard, and that credit belongs on your side of the ledger rather than in the customer’s discount.

What do downspouts and height do that the per-foot number hides?

They change the answer by more than double on the same footage. Take the identical 168 ft of eave and change nothing but the house and the metal.

Scenario	Crew hours	Material	Price at 32% margin	Effective per foot
Single-story ranch, 6 drops, .027 aluminum, tear-off	8.5	$610	$2,190	$13.04
Two-story colonial, 9 drops averaging 22 ft, same footage	12.5	$840	$3,140	$18.69
Same ranch in 16 oz copper, soldered joints	10.5	$2,950	$5,940	$35.36

Nobody with a published flat per-foot price can quote all three of those houses and stay solvent. Publish the ranch number if you want a number on the truck, then quote the actual house.

Height also changes the risk profile, which is a cost even when nothing goes wrong. Ladder setup, tie-off, and staging time on a three-story elevation are real hours, and OSHA’s ladder requirements under 29 CFR 1926.1053 govern how that work has to be set up. Price the setup, do not absorb it.

Which add-ons get their own line?

Anything the customer can accept or decline without changing the gutter itself.

• Gutter guards, per linear foot by product class. Foam, brush, screen, micro-mesh, and reverse-curve are different materials with different install rates, and a mesh that requires screwing into the shingle line is a different job from one that clips.
• Tear-off and disposal, per foot of old gutter, quoted whether or not scrap covers it.
• Fascia and drip edge repair, as a conditional allowance. Write it as “up to X feet of fascia board replacement included; beyond that, $Y per foot,” approved by text before you cut. Rotten fascia behind old gutter is the single most common mid-job surprise in this trade.
• Underground drain tie-ins or splash blocks, per drop.
• Cleaning, priced by stories and home size, with a stated flush-and-check scope. It is not a per-foot service and pricing it that way makes small houses uneconomical.

What does the math look like on a 168-foot ranch?

Single-story ranch, 168 ft of 5” K-style seamless aluminum, four corners, six downspouts at roughly 12 ft of stock each, existing aluminum torn off and hauled.

Step	Calculation	Amount
Crew time — load and drive 0.7, tear-off 1.4, machine setup and forming 0.7, hang 3.1, downspouts 2.1, cleanup and magnet sweep 0.5	8.5 crew hours × $73.65	$626.03
Overhead	8.5 × $30.00	$255.00
Material	From the table above	$610.24
Total cost		$1,491.27
Price at 32% margin	$1,491.27 ÷ 0.68	$2,193.04
Quoted	Rounded	$2,190.00

That works out to $13.04 per linear foot with the downspouts inside it. Now run the number the customer heard from somebody else: 168 ft at $9 a foot is $1,512, against a cost of $1,491.27. That job pays 1.4 percent margin — a day of two people’s labor, a truck, a machine, and a ladder, for about twenty dollars. This is how gutter companies go out of business while staying busy.

Is that 32 percent a markup or a margin?

Margin is the share of the invoice that stays with you. Markup is a number added to cost. Mixing them is the quietest way to lose a fixed slice of every job.

Take the same $1,491.27 and add 32 percent as a markup: $1,968.48. The margin on that is 24.2 percent, not 32, and the job comes in $224.56 light. Across a hundred replacements a year, that is a truck and a machine you did not buy. The arithmetic for a target margin is division, not multiplication — divide cost by 0.70 for a 30 percent margin, by 0.68 for 32, by 0.65 for 35.

How do I sanity-check my per-foot price?

Convert the quote into numbers you can compare against your own history before you look at anybody else’s.

• Revenue per crew hour. $2,190 over 8.5 hours is $257.65. That figure should be steady across job types; a two-story that comes in far below it was mis-estimated on ladder time.
• Material as a share of revenue. $610.24 against $2,190 is 27.9 percent. Copper jobs blow past that legitimately, aluminum jobs should not.
• Price per downspout. Useful for spotting quotes where the drops were never really counted.

For an outside check, price the same house three ways with local competitors rather than reading a national average. Published averages blend metros that never bid against each other, and aluminum coil, fuel, and labor move on their own schedules. Track your close rate as the real signal: a quote that wins almost every time is priced under the market, and the cure is not a smaller number. Setting money aside from the wins is its own discipline, covered in how much to set aside for 1099 taxes.

What gets recorded after the last downspout goes on?

The coil invoice, the scrap ticket, the supply-house run, and the miles. All four decide whether next season’s per-foot number is real.

Keel handles that from the truck. The invoice goes out from the driveway before the ladders are strapped down, carrying your own numbering, your logo, your brand color, and your payment link as a QR code the homeowner scans off your screen. Coil and accessory receipts get photographed at the supply counter and read on the device by Apple Intelligence, so the $1.22 per foot in your material table is this month’s number and not last spring’s. Every trip to the supplier and every drive between elevations logs as mileage; the deduction list that sits behind it is in self-employed tax deductions. Nothing leaves the phone — no account, no bank connection, no cloud, and an App Store privacy label that reads Data Not Collected. Freeboard shows cash minus your tax reserve minus committed invoices, which on a trade with seasonal swings is a more honest number than a bank balance. The Accountant Pack exports a CSV and a one-page summary at year end, and the whole year leaves as a single file. Keel is free with unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 Lifetime purchase, not a subscription.

Frequently asked questions

How much should I charge per linear foot for gutter installation?

Derive it rather than adopting it. Add your crew hours at a loaded rate, add coil, hangers, miters, outlets, downspout stock, and elbows, add overhead, then divide by one minus your margin and divide that total by the run length. The per-foot figure that falls out is specific to that house — a two-story with nine drops will land far above the same footage on a ranch.

Should downspouts be included in the per-foot gutter price?

No. Quote them per drop with the height stated, because drop height and count vary independently of eave footage. A house with 120 feet of gutter and eight three-story drops is a bigger job than one with 180 feet and four short ones. Separating them also lets a customer compare your run price honestly against a competitor’s.

How much more should I charge for copper gutters?

Reprice the job, do not apply a multiplier. Copper stock costs several times aluminum per foot, the accessories cost more, joints are often soldered rather than sealed, and the material dents if handled carelessly, so both the material lines and the hour count go up. Quote copper as a separate build with its own material sheet priced from a current supplier invoice.

How do I price gutter cleaning versus gutter installation?

Differently, and on a different unit. Cleaning is priced by number of stories and home size with a defined scope — debris removed, downspouts flushed, hangers checked — rather than by linear foot, because the cost driver is ladder repositioning and access rather than length. Set a minimum that covers the drive, and price second and third stories as separate tiers.

What do I do when I find rotten fascia after tear-off?

Price for it in advance as a conditional line. Write a stated allowance into the quote — so many feet of fascia replacement included, a per-foot rate beyond it — and get anything past the allowance approved by text with a photo before you cut. Rotten board behind an old gutter is the most common mid-job surprise in this trade and the easiest one to convert into a fight.

How many downspouts does a gutter run need?

Plan one per 30 to 40 feet of run, then verify it against the roof area draining into that section. A 2x3 downspout handles roughly 600 square feet of roof and a 3x4 roughly twice that, so a steep or large plane, or a region with heavy rainfall, drives both the count and the outlet size up. Undersizing shows up as overflow and becomes a warranty visit.
