Gutter installation is relatively straightforward, which means the competition is fierce and the temptation to cut corners on gauge, hangers, and pitch is high. These questions identify contractors who do it right.

## The 10 Questions — and Why Each One Matters

A contractor who answers these confidently, with specifics, is demonstrating the transparency and competence that separates good work from mediocre work.

1

### “Are these seamless gutters fabricated on-site, or sectional gutters?”

**Why this matters:** Seamless gutters are formed from a single continuous piece cut to length on-site, eliminating joints along the run where leaks develop. Sectional gutters have seams every 10–20 feet. For a permanent installation, seamless is strongly preferred. Get confirmation in writing.

2

### “What gauge aluminum are you installing — 0.027" or 0.032"?”

**Why this matters:** Residential gutters typically come in 0.027" (standard) or 0.032" (heavy duty). In areas with heavy snow load or ice, 0.032" is worth the modest premium. Cheap contractors often use 0.025" — ask specifically.

3

### “How many downspouts are included, and where will they terminate?”

**Why this matters:** Standard practice is one downspout per 30–40 linear feet of gutter. Ask where each downspout terminates — splash blocks and extensions directing water 4–6 ft from the foundation are standard. Underground drainage connections are an upgrade worth asking about.

4

### “Do you inspect and replace rotted fascia, and at what price per linear foot?”

**Why this matters:** Gutters screw into fascia. If fascia is rotted, new hangers won't hold. Most gutter contractors can replace fascia boards — ask the price per linear foot so you have a clear cost if rot is discovered during installation.

5

### “What gutter guard system do you recommend, and can you explain why over alternatives?”

**Why this matters:** Micro-mesh guards outperform screen and reverse-curve guards in independent testing. A contractor who recommends a specific system should be able to explain the performance difference, not just the margin they make on it.

6

### “How do you pitch the gutters — what slope do you use per foot of run?”

**Why this matters:** Standard pitch is 1/4" drop per 10 linear feet toward the downspout. Ask how they establish and verify pitch during installation. Gutters pitched by eye often sag and hold water.

7

### “What fastener system are you using — screws with ferrules, or spikes?”

**Why this matters:** Gutter spikes (the old standard) pull out over time with freeze-thaw cycling. Gutter screws with hidden hangers hold significantly better and are the current standard. If a contractor is still using spikes on new installations, that's a quality signal.

8

### “Are you licensed and insured in my state?”

**Why this matters:** Gutter installation is regulated in many states. Liability insurance covers property damage during installation. Workers' comp is important given the ladder work involved.

9

### “What warranty do you offer on materials and on your installation labor?”

**Why this matters:** Product warranties on aluminum gutters typically cover materials for 20 years. Labor warranties vary: 1 year is minimal, 5 years is good. Ask what specifically is covered — pulling away from fascia, leaking joints, improper pitch.

10

### “What is your process for downspout extensions and splash block placement?”

**Why this matters:** Water discharged at the foundation is the whole problem gutters are solving. Ask where each downspout exits and how extensions direct water away from the home. This detail is often neglected in basic bids.

## Red Flags to Watch For

Any of these during your contractor search should prompt closer scrutiny or disqualification:

- Proposes sectional gutters where seamless is available
- Can't specify the gauge of aluminum being installed
- No inspection of fascia condition before bid
- Payment required in full before installation begins
- Pushes highest-margin gutter guard without explaining performance differences
