Is my gutter installation quote complete?

Look for these in a complete gutter installation quote: linear footage for every run, continuous runs formed on site or joined sections, the material, gauge and profile size, where each downspout sits and drains, hanger spacing, fascia repair, old-gutter disposal, permit and payment terms, plus the work, materials, completion date and price the FTC lists for written estimates.

Key facts

What should a written gutter installation quote list?

Ask that your gutter installation quote split the house into named runs, give the linear footage of each, and state the material, gauge, profile and width, how many downspouts go where, the hanger type and spacing, the end caps, miters and outlets, plus a start date and finish date.

In its consumer guidance on home improvement, the Federal Trade Commission writes: "A written estimate should include a description of the work to be done, materials, completion date, and the price." On a gutter job, the work description is where you can see whether two bidders are proposing the same system or quite different ones.

  1. Runs and footage: Which sides of the house are covered, and what length does the quote give for each run from corner to corner?
  2. Forming method: Will runs be formed on site from coil into continuous lengths, or joined from stock sections? Where would any joint sit?
  3. Material and gauge: Aluminum, vinyl, steel or copper, and in which gauge or thickness and colour?
  4. Profile and width: Which profile, such as K-style or half-round, and which width is proposed, and do the downspouts match that size?
  5. Downspouts: What number, at which corners, and does each one discharge onto a splash block, into an extension pipe or into a buried drain?
  6. Hangers and trim: Which hanger or bracket is used, at what spacing, fastened into what, and are end caps, inside and outside miters, outlets and elbows counted?

Ask how each run will be pitched toward its outlet, and whether a long run or a large roof face draining into one corner gets a second downspout. A bidder who adds or drops an outlet compared with your request should say why in writing, so you can weigh that choice rather than discover it after the ladders come down.

InstaBids gets you competitive written quotes without calls or home visits to bid; contractors never pay to see a request or to bid, and there is no fee during our pilot.

Which items are often left out?

Use this list of possible gaps when a gutter installation quote is silent: removal and disposal of the old gutters and hangers, soft fascia or soffit boards found behind them, the drip-edge and roof-edge interface, downspout extensions, guards, ladder access over planting beds, and paint touch-up where old fasteners come out.

Ask what happens if the crew takes down the old gutter and finds rotted fascia. Have the bidder mark fascia and soffit repair as included, listed separately or excluded, and put any change order for extra boards in writing for your decision before new gutter goes up on damaged wood.

If a new roof is going on at the same time, ask whether replacing damaged fascia belongs to the roofing job or to the gutter job, and check that both written quotes draw that line in the same place, so neither crew assumes the other is fixing the boards.

Ask how the back of the new gutter meets the roof edge. Does it tuck under an existing drip edge or flashing, will any shingle or tile be lifted, and who answers for roofing material disturbed while hangers go in? On a tile roof, ask where the crew will stand and how brackets are fastened without cracking tiles.

DBPR's construction-industry page, read 15 October 2026, describes roofing work this way: "Roofing contractors have the experience, knowledge, and skill to install, maintain, repair, alter, extend, or design and use materials and items used in the installation, maintenance, extension, and alteration of all kinds of roofing, waterproofing, and coating, except when coating is not represented to protect, repair, waterproof, stop leaks, or extend the life of the roof." If a gutter bid includes lifting, replacing or sealing roof covering at the edge, ask whether that part is roofing work and who will carry it out.

If guards appear in the quote, ask for the type and material, whether they attach at the roof edge or the gutter lip, and whether every run gets them or only some. Ask your roofer whether a guard that slides under the first row of shingles or tiles affects any roof warranty you hold.

For a downspout that drains into a buried pipe, ask whether connecting, clearing or replacing that pipe is part of this quote. Then ask where ladders and the debris pile will go, how the crew keeps planting beds, pavers and any pool enclosure below the eaves from damage, and whether old gutters, hangers and downspouts leave with the crew.

What should the payment terms say?

Compare your payment schedule with the visible stages of a gutter job: materials on site, tear-off of the old system, any fascia work, new runs and downspouts hung, and a final walk-through where you watch water run to each outlet. Ask what any first payment pays for and when each later one falls due.

The FTC's advice includes this line: "Don’t pay the full amount for the project up front." The same passage ends: "And never make the final payment until the work is done and you’re satisfied with it." Link the last gutter payment to that walk-through, after downspout extensions and clean-up are done.

Before you sign, the FTC also says: "And, make sure all blank spaces are filled in." On a gutter contract, check the footage, downspout count, colour, start date and finish date in particular, because those are the lines that let you hold the finished job against what you agreed.

Among the hiring tips Palm Beach County posts on its Contractor Regulations page, read 15 October 2026, is this one: "If you want to pay cash - get a receipt." Ask for a written receipt for every payment, naming the stage of the gutter work it covers.

Ask how a change order is written and approved when the crew finds extra rotted boards, needs another downspout or measures more footage on the day. Ask that each change order show its effect on the payment schedule before work continues, so you see the new total before you agree to it.

Does the quote say who pulls the permit?

Ask whether your address needs a permit for this gutter job, which party applies, who schedules any inspection and who hands over the final closeout paperwork. Look for the contracting business's name on the quote, and ask a bidder who thinks no permit applies to say so in writing.

Palm Beach County's hiring tips on that Contractor Regulations page, read the same day, add: "Do not make the final payment until the permit is closed out." Where a permit is issued for your gutter work, ask how the closeout lines up with the last payment on your schedule.

Section 489.117(4)(a)3 of the Florida Statutes, as read on 15 October 2026, says: "A local government may continue to offer a license for veneer, including aluminum or vinyl gutters, siding, soffit, or fascia; rooftop painting, coating, and cleaning above three stories in height; or fence installation and erection if the local government imposed such a licensing requirement before January 1, 2021." Whether a local requirement of that kind reaches gutter work at your address is a question for the building department there; looking up any public record yourself is optional.

On DBPR's construction-industry page, also read 15 October 2026, another contractor category is described this way: "CS and RS – A “sheet metal contractor” means a contractor whose services are unlimited in the sheet metal trade and who has the experience and skill necessary for the manufacture, fabrication, assembling, handling, erection, installation, dismantling, conditioning, adjustment, insulation, alteration, repair, servicing, or design of ferrous or nonferrous metal work of U.S. No. 10 gauge or its equivalent or lighter gauge." If your quote includes custom fabricated metal work, a roof replacement or structural repair beyond ordinary aluminum or vinyl gutters, ask the bidder and the building department which category of work the job falls under.

What should my request include?

Describe each side of the house that needs gutters in a single written scope that gives rough run lengths if you know them, the material and colour you want, where water should go at each corner, and any rotted fascia you can see. Add a photograph of every corner, existing downspout and roof edge.

Contact details stay hidden until the homeowner picks a contractor and they confirm the connection.

How can I compare it with other written quotes?

Compare the gutter installation quotes side by side on total footage, forming method, material and gauge, profile width, downspout count and placement, hanger spacing, then removal, fascia repair, start date and finish date. Ask any bidder whose footage or downspout count differs from the others to explain how it measured your house.

  1. Footage: Do the totals cover the same sides of the house, and where they differ, which run was measured differently?
  2. Outlets: Do the quotes agree on how many downspouts there are, which corners they serve and what size they are?
  3. Roof edge: Does each quote say the same thing about fascia repair, drip edge and contact with the roofing?
  4. Add-ons: Are guards, extensions and underground connections included, offered as options or absent in each one?
  5. Clean-up and dates: Which quotes name a start date, a finish date and a plan for hauling away the old system?

Keep an upgrade such as guards, a wider profile or copper as a separate option instead of folding it into your base request. If one bidder points out something you missed, such as a roof valley that sends heavy flow toward one corner, add it to the written scope and send the revised version to every bidder.

With the footage, downspout and roof-edge answers recorded, send that one written scope to every bidder, so the competing written responses you get back all answer the same job.
