9 things gutter salespeople won't tell you

None of this is a conspiracy. Most gutter contractors are honest people doing a physical job well. But there are things that are true, useful to you, and not in anyone's interest to volunteer while standing in your driveway. Here are nine.

1. "Lifetime warranty" is on the paint

Your quote likely contains three different warranties pretending to be one. The lifetime is the manufacturer's finish warranty — paint chipping and fading. The one that actually protects you is workmanship, and it's typically 1–5 years.

Which matters because gutters fail from installation, not material. Pitch, hangers, sealed miters. The aluminum will happily outlive a bad install by twenty years, sitting in your bushes. Ask: lifetime on what, exactly? See the warranty guide.

2. The gauge is quietly negotiable

Aluminum comes in .027 and .032. Most competitive bids quote .027 because it's cheaper and you'll never ask. The .032 resists ladder dents, holds shape under ice, and stays straight between hangers for years longer. The upcharge is small.

Two quotes $400 apart are sometimes just this. Ask every bidder which gauge. The good ones answer in one second. See material guide.

3. Hanger spacing is where the corner gets cut

Hangers should be every 24–36 inches — 12–18 where snow loads. Hangers are cheap; the labour to install them isn't. A crew spacing at 48 inches saves real time on your job and you cannot see it on day one. You see it in year three, as a gentle scallop where water pools.

Get "hidden hangers, screwed, 24″ on centre" written on the quote. See gutter hangers.

4. Guards don't stop ice dams

Ice dams come from attic heat melting roof snow that refreezes at your cold eaves. Guards keep the trough clear — which genuinely helps, because standing leaf-water is what a dam anchors on. But they don't touch the cause, and no guard fixes a warm attic.

Anyone selling guards as an ice-dam solution is overselling. See do guards cause ice dams.

5. "Never clean your gutters again" isn't true

Good micromesh takes you from 2–3 cleanings a year to an inspection and a light brush-off every year or two. That's a genuinely large win — worth paying for. It is not zero, and "lifetime no-clog" guarantees usually come with annual inspections you pay for, exclusions for pine needles and shingle grit, and a remedy that means "we'll come clean it."

This is the single thing homeowners feel most misled about afterward. See guard types compared.

6. The national brand premium is 40–70%

National guard brands spend enormously on marketing and typically quote 40–70% above local seamless specialists installing comparable stainless micromesh. On the same house that's routinely thousands of dollars for a functionally similar product.

Our own data makes the point: a national guard brand's local presence in our dataset carries 4.4★ on 8 reviews, while local gutter specialists nearby run 4.8–4.9 on hundreds. The marketing budget and the local trust are not the same asset. Always get one local quote alongside the brand-name pitch.

7. Your fascia is the real number

The old gutters come off and the board behind them is soft — extremely common on NJ homes that have overflowed for a few seasons. It has to be fixed first, because hangers won't hold in rotted wood.

A good contractor probes the fascia at the estimate and prices it in. A cheap bid discovers it on the day, as a change order, when you have no leverage and a crew in your driveway. Ask: "did you probe the fascia?" The answer tells you which kind of bid you're holding. See fascia cost.

8. Sometimes you need a $250 part, not a $2,800 system

Overflow that only happens in heavy rain is usually capacity — one downspout on a 50-foot run. That's $150–$400, not a replacement. Sagging is usually hangers, $200–$500. Water behind the gutter is a missing drip edge. A waterfall at one corner is a $15 splash guard.

None of those are replacements, and all of them get quoted as one. See the $2,800 quote that should have been $250.

9. The price doesn't expire tonight

"This price is only good today" is a sales technique, not a business constraint. Aluminum coil pricing does not change overnight. Any legitimate quote is still there next week.

When someone needs your signature before you can get a second opinion, they've told you something useful about the quote — and about themselves. Real contractors are booked out; they'd rather you called back in a week than felt cornered.

The six questions, in one place

AskGood answer
Which gauge — .027 or .032?Instant, specific
Hanger type and spacing?"Hidden, screwed, 24″ on centre"
Is tear-off and disposal included?Yes, in writing
Did you probe the fascia?Yes, and here's what I found
How long is the workmanship warranty?A number, not "lifetime"
What's your 13VH number?Given immediately — why

Six questions. Two minutes. A contractor who answers all six without hesitating is one who'd defend their own work — and that's most of what you're actually trying to find out.

Why we published this

We get paid when homeowners get matched with contractors, so an article teaching you to slow down, ask hard questions, and sometimes buy the $250 fix instead is not obviously good for our margin.

It's good for the thing underneath it. A homeowner who gets a fair job from someone on our list comes back and tells their neighbour. That's the entire business model, and it only works if the list is honest. See how we rank.

FAQ

What should I ask a gutter contractor before hiring?

Ask which aluminum gauge they are quoting (.027 or .032), what hanger type and spacing, whether tear-off and disposal are included, whether they probed the fascia, how long the workmanship warranty runs, and for their NJ 13VH registration number. A good contractor answers all six instantly.

What does a lifetime gutter warranty actually cover?

Almost always the paint finish against chipping and fading — not the installation, and not the gutter staying attached to your house. The workmanship warranty is the one that matters and it is typically only 1 to 5 years.

Do gutter guards stop ice dams?

No. Ice dams are caused by heat escaping into the attic and melting roof snow, which then refreezes at the cold eaves. Guards help by keeping the trough clear of the standing water a dam anchors on, but they do not address the cause.

Are gutter salespeople pressuring me for a reason?

A price that expires today is a sales technique, not a business constraint. Real materials pricing does not change overnight. Any legitimate quote is still available next week, and a contractor who says otherwise is telling you something useful about themselves.
