Before hiring a gutter cleaner, ask five things: are you insured, will you put the quote in writing, what method do you use, will you provide photo proof, and do you guarantee your work. A professional answers all five without hesitation. A chancer stumbles on at least one — and that stumble tells you everything you need to know.

Gutter cleaning is an easy trade to enter and a hard one for customers to verify, because the work happens above your eyeline. Therefore, the questions you ask before booking matter more than in almost any other home service. Here are the five that do the filtering for you.

1. Are You Insured — and For How Much?

This is the non-negotiable first question. Gutter cleaning involves working at height around your roofline, and things can go wrong: a dropped tool through a conservatory roof, a damaged gutter joint, an injury on your property. Without insurance, any of those problems lands on you.

Ask specifically about public liability insurance and the level of cover. Any established firm will state its cover level and provide proof of insurance on request. However, if a trader gets vague, changes the subject, or says “nothing’s ever gone wrong,” treat that as your answer.

2. Will You Give Me a Written Quote?

A verbal price over the phone is not a quote — it is an opening position. The classic doorstep pattern is a low number to win the booking, followed by “it was worse than expected” once the work is half done and you have little choice but to pay.

A written quote closes that door. It records the price, what the price includes, and what would genuinely count as extra work. For example, our quotes are free, written, and no-obligation, and the price covers the full job: gutter clearance, downpipe flushing, and flow testing. Additionally, a firm that quotes in writing is a firm you can hold to its word — which is precisely why the good ones volunteer it.

3. What Method Do You Use?

The method determines the safety, the mess, and the quality of the result. Broadly, you will hear one of two answers: ladders and a bucket, or a vacuum-pole system operated from the ground.

Vacuum cleaning has significant advantages. Nobody climbs on your property, debris goes into a sealed drum rather than onto your garden, and there is no pressure-washing water forced behind fascias or under tiles. We covered the system in depth in our SkyVac explainer, but the short version is this: ground-based vacuum cleaning is safer for the operator, tidier for you, and gentler on the gutters.

Ask the question even if you do not mind the answer, because how a trader talks about their method reveals their professionalism. Someone who can explain their process step by step — inspection, clearance, flush, report — is running a proper service, not improvising on your driveway.

4. Will I Get Photos of the Work?

Here is the awkward truth about gutter cleaning: from the ground, a cleaned gutter and an untouched gutter look identical. You are paying for work you cannot see, so proof matters.

Professional firms solve this with before-and-after photos supplied with every job. The photos show the state of the gutter channel before the clean and the clear, flowing channel afterwards. As a result, you know exactly what you paid for — and you also get an honest record of any damage spotted along the way, such as failing joints or sagging brackets, with a separate quote if repairs are recommended.

If a trader cannot or will not provide photos, you are being asked to take the work on faith. In a trade where the results are invisible from the pavement, that is a poor deal.

5. Do You Guarantee Your Work?

The final question separates firms that plan to be around next year from those that do not. Ask what happens if a downpipe blocks again the week after the visit, and ask whether any repair work is guaranteed.

A confident answer sounds specific. For instance, we flush and flow-test every downpipe before we leave, and our repair work carries a 12-month workmanship guarantee. Meanwhile, an evasive answer — “it’ll be fine” — leaves you with no comeback if it is not fine.

Longevity is part of the same picture. A business serving the same area for years has a local reputation to protect. In particular, check for a track record of reviews in your area, whether that is Uxbridge, Harrow, Hayes, or anywhere in between.

The Quick Checklist

Before you book anyone, confirm all five:

Insurance — public liability, with a stated cover level and proof available.
Written quote — free, itemised, no-obligation.
Method — a clear explanation, ideally ground-based vacuum cleaning.
Photo proof — before-and-after photos with every job.
Guarantee — flow-tested work, with guaranteed repairs.

Anyone who passes all five is worth your money. Anyone who fails one is worth a second thought.

Frequently Asked Questions

How do I check a gutter cleaner is actually insured?

Ask for proof — a reputable firm will provide its insurance documentation on request. Check the policy covers public liability at a meaningful level; £1 million is a minimum, while established firms often carry £5–£6 million.

Should a gutter cleaning quote be free?

Yes. A free, written, no-obligation quote is the industry standard among professional firms. Be cautious of anyone charging for a quote or refusing to commit a price to writing.

What should be included in a gutter clean?

At minimum: full debris removal from the gutter channel, downpipe clearing and flushing, a flow test to confirm drainage, and photos of the finished work. Recommendations for any repairs should come as a separate written quote.

Is the cheapest quote a bad sign?

Not automatically, but pair the price with the five questions above. A rock-bottom price with no insurance, no written quote, and no photo proof usually costs more in the end than a fair price from an accountable firm.
