Judge a gutter company on three things: whether it is licensed and insured for the work, whether it will put a specification in writing, and how it answers the question of what happens if the fascia turns out to be rotten. The third one is the most revealing.
Gutter Answers connects you with licensed local companies. We are not a contractor and do not perform the work ourselves.
These are checks, not conversation. Do them before you spend time on quotes, because they remove companies from the list quickly.
Licensing rules for this trade are set by states and often again by cities and counties, so what applies to you depends on where you live. That is a reason to check locally, not a reason to skip the check.
Anyone can quote a price. The questions below ask about the decisions behind the price, and the quality of the answers is the real signal.
A company that answers these plainly and without irritation is usually the one to use, even if it is not the lowest number.
A number on its own is not a quote, because it cannot be compared with another number attached to different work. Ask for the specification in writing before you commit to anything.
| Should be written down | Why it matters |
|---|---|
| Linear feet of gutter | The basis of the price |
| Material, gauge and profile | Two aluminum quotes are not the same quote |
| Seamless or sectional | Decides where the run will eventually leak |
| Downspout count and discharge points | Undersizing here causes overflow later |
| Hanger type and spacing | Decides whether it sags |
| Fascia assumption and what changes it | The most common source of a revised bill |
| Tear-off and disposal | Otherwise it appears as an extra |
| Payment schedule | A large deposit before materials arrive is a flag |
| Warranty terms | Materials and workmanship are different promises |
None of these proves bad faith on its own. Two or more together is a pattern worth acting on.
At least three, and on the same written specification, otherwise you are comparing different jobs rather than different prices. If one quote is dramatically lower than the others, the useful question is what it leaves out.
The lowest quote is sometimes the right one. It is only the right one once you know why it is lower.
It depends where you are. Licensing for this trade is set at state level and sometimes again by the city or county, and requirements change. Ask the company directly and verify what it tells you with the issuing body.
A modest deposit to secure materials and a slot is normal practice. A request for a large share of the total in cash before anything has been ordered is a different proposition and worth questioning.
Not without doing the same checks you would do on anyone else, and those checks matter more here rather than less. Verify licensing and insurance, get the specification in writing, and compare it against other quotes.
Not by itself. It becomes a bad sign when nobody can explain what makes it cheaper. Thinner gauge material, sectional instead of seamless, fewer downspouts and an excluded fascia all reduce a price legitimately, and all change the job.
Ask what is covered and by whom. Material warranties come from the manufacturer, workmanship warranties come from the company that did the work, and they are not interchangeable. Get both in writing.
