The short answer
The single most useful question is what roof area they measured and how many downspouts that gives. Capacity is calculated from area, pitch and rainfall — a company that hasn’t worked it out is repeating whatever was on the house before, including its faults. The second most useful is whether they’ll send photos of what they found up there, since that’s the only way to verify work you can’t see.

How guards attach
Three kinds of company
They quote for the same job and deliver quite different things.
Worth hiring
The one that measures
Asks about the roof, looks at the fascia, tells you the downspout count and why. Quotes fascia repair separately rather than discovering it mid-job.
Depends
The route cleaner
Fast, cheap, does the channel and moves on. Fine for a straightforward clean on a house with no complications. Won’t diagnose anything.
Walk away
The storm-chaser
Appears door-to-door after severe weather, offers a price today only, wants payment up front. Running a route, not responding to your roof.
Why photos matter more here than in most trades
Gutter work happens where you can’t see it. You cannot inspect a cleaned channel from the ground, you cannot confirm a downspout was cleared, and you cannot tell whether the fascia was even looked at.
Which makes before-and-after photos the only real verification available, and makes a company that offers them unprompted worth more than one that’s slightly cheaper. It is also the single question that most reliably changes how carefully a job gets done.
Five questions on the call
You’re listening for whether they ask you anything back.
What roof area are you working from?
Sizing follows from it. Vagueness here means the system is being guessed at.
How many downspouts, and why that many?
A number with a reason. “One at each end” without reference to the roof is habit.
Will you send photos?
Before and after. The only verification you have for work you can’t see.
What happens if you find soft fascia?
Priced separately, or renegotiated on the day? The answer tells you how the rest of the job will go.
Do you clear the downspouts too?
Clearing the channel and leaving a blocked spout is half a job and it’s common.
Reading the quote
Where this stops being a DIY job
Anyone door-knocking after a storm. Legitimate companies are booked solid after severe weather, not walking streets. Take a card, verify the business separately, call them yourself.
Full payment up front. A deposit on materials is normal for installation. Paying the whole amount before work starts leaves nothing holding anyone to finishing it.
Any quote for work at height that hasn’t seen the property. Access is most of the cost, and access can’t be assessed over the phone.
What a good company does on the first visit
Looks
Walks the perimeter
Checks fall, fascia and discharge points before opening a laptop.
Explains
Names the failure
Tells you what’s wrong and why, rather than what package you need.
Documents
Photographs it
Offers evidence rather than waiting to be asked for it.
Common questions
How do I know if a gutter company is any good?
Ask what roof area they measured and how many downspouts that gives. Sizing follows from measurement — a company that hasn’t worked it out is repeating whatever was there, faults included.
Should I use a company that knocks on my door?
No. Legitimate firms are fully booked after storms rather than walking streets. Take the details, verify the business independently, and call them yourself.
How much should I pay up front?
A deposit on materials is normal for installation. Full payment before work starts isn’t — it removes any incentive to come back and finish.
What should be in a gutter quote?
Roof area or run length, number and placement of downspouts, material and whether it’s seamless, any fascia repair priced separately, and where water discharges.
Want someone who measures before they quote?
The questions above cost nothing and they filter out most of the bad outcomes in this trade — the guessed sizing, the half-done clean, the storm-chaser. Asking them is the highest-value thing you can do before anyone gets on a ladder.
