1. Do you clean the gutters before installing guards?
The answer must be yes — a full clean-out, not a quick scoop. Guards lock in whatever is underneath. An installer who guards over packed leaves is selling you a hidden problem.
2. How do you check the gutters and fascia first?
Listen for specifics: hanger check, pitch check, fascia probing. "We take a look" is not an inspection. You want to hear what they check and what happens if they find rot.
3. Which guard do you recommend for my trees — and why?
The recommendation should follow your trees, not their inventory. Pines demand micro-mesh. Hardwood-only lots can take screens or hoods. If they recommend the same guard for every home, they are selling product, not solving problems.
4. How is the guard fastened?
You want to hear a real fastening method — screwed to the gutter lip, locked under the shingle course, manufacturer-spec brackets. "It just sits in there" means the first windstorm rearranges your investment.
5. What happens at corners, valleys, and downspout outlets?
These are the failure points. Corners need fitted pieces, not bent scraps. Valleys need guards that take concentrated flow. Downspout outlets need clear openings. Vague answers here mean sloppy work later.
6. Do you water-test after install?
Yes is the only acceptable answer. A hose run at full flow, watching every downspout, before the crew leaves. No test, no proof it works.
7. Is the price in writing, and what exactly does it include?
Written price, itemized scope: linear feet, guard type, clean-out included, repair items listed separately. Verbal quotes evaporate. "Starting at" prices are not quotes.
8. What maintenance do the guards need?
Any honest installer names the maintenance: surface brushing every year or two, what to watch for, what it costs if they do it. "Zero maintenance forever" is a lie — walk away.
9. What is the warranty — on the product and on the work?
Two warranties matter: the manufacturer's product warranty and the installer's workmanship warranty. Get both in writing, and know who to call for each. Our warranty guide explains what the fine print usually says.
10. Can I see the guard sample and hold it?
A pro carries samples. Hold the mesh up to the light. Flex the frame. Ask what it is made of. You are about to put this on your house for decades — touch it first.
Red Flags That End the Conversation
Pressure to sign today for a "today only" price. A quote given from the driveway without a ladder going up. Badmouthing every competitor instead of explaining their own work. No written anything. Trust your gut — the gutter business has good operators and fast talkers, and these questions tell them apart in ten minutes.
For reference, here is how we answer all ten: our installation process, our free inspection, and our written estimates.
