A blocked kitchen sink or a floor drain backing up is not something you can leave until Monday. Drain cleaning in Hong Kong is a small enough category that the companies here carry just 352 Google reviews between them, and ratings swing from 4.0 up to 4.9, a wider spread than you would expect. That gap is worth reading closely: the busiest name has nearly six times the reviews of the smallest, so proven volume, not just the star average, decides who to call first.
Short answer: The most-reviewed drain company in Hong Kong here is Jelaine Drainage (燕寧渠務), with a 4.9 rating across 169 Google reviews, by far the highest volume on this list, followed by 便宜坊冷氣服務 (4.9, 65 reviews) and 水電道 (4.8, 45 reviews). Most Hong Kong drain specialists send a master to quote free on site and agree a fixed price before starting, so book the visit, then confirm the number in writing.

便宜坊冷氣服務
4.9★★★★★65 Google reviews
便宜坊冷氣服務 is a Hong Kong home-services company whose core trade is air conditioning, installation, repair, deep cleaning and maintenance across homes, offices, clinics and restaurants. On the drainage side its technicians deal mainly with the water problems that come with aircon: blocked condensate outlets, dripping and leaking units. The company advertises same-day call-outs, transparent pricing and 24-hour service, and it is based around Kowloon City. It is an aircon specialist rather than a general sewer-and-floor-drain crew.
What people praise
- Reviewers describe fast, clean, careful visits
- One customer praised nearly two hours of patient work replacing an aircon drainage outlet
- Same-day service and 24-hour availability
- Strong repeat recommendations
Worth knowing
- Its main trade is air conditioning, so drainage work centres on aircon water outlets rather than sewer or floor drains
- A smaller review base of 65, a good early record rather than a long one

Our take: Rated a strong 4.9, but on a modest 65 reviews and with air conditioning as its real focus. Best if your blockage is aircon-related; for a clogged floor drain or main pipe, start higher on this list.

Our take: A dependable, do-most-things repair firm for Kwai Chung, Tsuen Wan and Tsing Yi. We rank it just below the higher-rated names on a smaller, more general review base, but locally it is a solid call.

Handyman Galaxy - Painting & Wall Repair in Hong Kong
4.7★★★★★45 Google reviews
Handyman Galaxy is a general repair and handyman outfit serving Hong Kong from Ho Man Tin. Its own site leans on painting and wall repair, but reviewers hire it for plumbing jobs, a burst shower pipe, a new faucet, a toilet swap, plus locks and keys, often on very short notice. The team is known for responding quickly, including on Sundays, and finishing the work cleanly. Think of it as a fast, do-a-bit-of-everything option rather than a dedicated drain crew.
What people praise
- Responsive on short notice, including Sundays and urgent call-outs
- Fast, tidy work, one reviewer had a toilet and faucet replaced quickly and neatly
- Handles a wide range: plumbing, locks and keys, painting and wall repair
- Friendly, helpful staff by several accounts
Worth knowing
- Several reviewers say pricing can run high, especially for urgent jobs, confirm the quote before work starts
- A couple report quotes well above other contractors, so it is worth comparing

Our take: A quick, flexible handyman for odd repairs and after-hours fixes. We rank it here because it is a generalist, not a drain specialist, and because pricing feedback is mixed, get the number pinned down first.

4.0★★★★★28 Google reviews
This Mong Kok drain specialist (trading as 李師傅 / Frontline Drainage) runs a 24-hour emergency line and, by its own listing, describes itself as a government-registered, approved drain-clearing company with more than 30 years behind it. It focuses on unblocking toilets, sinks, floor drains, shop manholes and grease traps using high-pressure jets and steel-cable machines, and advertises external-wall access without scaffolding (免棚). Quotes are billed as 'clear it or you don't pay'. It is the most budget-minded emergency option here.
What people praise
- 24-hour emergency line with fast call-outs
- Reviewers have praised professional, reasonably priced work
- One detailed review credits patient work that checked the root cause
- 'No success, no charge' quotes and no-scaffolding access, per its own listing
Worth knowing
- The lowest rating here at 4.0, and recent feedback is mixed, a couple of reviewers report a blockage that returned or poor communication
- A modest review base of 28, with some of the praise dating back several years

Our take: We rank it #5 on the lowest rating on the list and a small, older review base with mixed recent feedback, not on the good early reviews alone. A low-cost emergency option, but get the fixed price and warranty confirmed before it starts.

Claim this spot › How we scored these companies
Every score on this page comes from public Google data on the date shown, not from opinion or payment. Rating is the live Google star average. Review volume is how many customers have rated each company, ranked against other Hong Kong drain firms. Confidence weighs the rating by that volume, so a 4.8 from dozens of people is treated more cautiously than the same score from thousands. Recency tracks how recently people are still leaving reviews. Drain cleaning is a smaller category here, so most review counts are modest, we lean on consistency and recency, and no business can pay to change these numbers.
What does drain cleaning cost in Hong Kong? (2026)
Hong Kong drain jobs are priced case by case, so a single figure would be guesswork. What moves the price: the type and severity of the blockage (a kitchen sink versus a floor drain, a shop manhole or a restaurant grease trap), how the drain is accessed (whether external-wall work or scaffolding is needed), the method used (a steel-cable or spring machine, high-pressure jetting, or a vacuum tanker for sewage), and the time of day, since after-hours emergencies cost more. The good news: most of the companies here send a master to inspect and quote free on site, then hold that fixed price. Get the number in writing before work begins, and ask whether a return visit is covered if the blockage comes back.
Serving every district in Hong Kong
The companies above cover Hong Kong Island, Kowloon and the New Territories, from Sham Shui Po, Mong Kok, Kowloon City and Ho Man Tin to Kwai Chung, Tsuen Wan and Tsing Yi, and across to Central, Causeway Bay and Sha Tin. Searching for drain cleaning near me? Each listing below shows a live phone number and directions, so you can reach the closest 24-hour option fast.
What to ask before you book a drain cleaner
- Is the on-site inspection and quote free, and will you confirm a fixed price before starting?
- Do you charge ‘no cure, no pay’ if the blockage cannot be cleared?
- What method will you use, a steel-cable or spring machine, high-pressure jetting, or a vacuum tanker?
- Is there a warranty if the blockage returns, and for how long?
- Can you reach the drain without external scaffolding (免棚), or is that an added cost?
- Are after-hours or emergency call-outs charged at a premium?
Frequently asked questions
How did you choose these drain cleaning companies?
We started from the drain-clearing companies in Hong Kong with a public Google presence, then ranked by rating, review volume, consistency and recency. Because this is a smaller category, we weighed how steady and recent the reviews are, not just the star average. See How we scored above.
Are these rankings paid?
No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.
How much does drain cleaning cost in Hong Kong?
It depends on the blockage, the access and the method, so there is no flat rate. Most of the specialists here inspect and quote free on site, then agree a fixed price before starting. Ask for that price in writing and check whether a return visit is covered if the clog comes back.
Do these companies offer 24-hour emergency drain service?
Yes, every company on this list shows 24-hour availability on Google. Confirm how quickly they can reach your district and whether an after-hours call-out carries a premium when you phone.
How often is this updated?
This page carries a verified date of July 2026. We refresh it periodically so the ratings and review counts stay current.
The bottom line
For most Hong Kong homes and shops, Jelaine Drainage is the safe default, the highest rating, by far the most reviews, English-speaking masters and a warranty. Whoever you call, get the fixed price in writing before the work starts and ask what happens if the blockage returns.
