By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 6 min read

Renovation work below ground level in Hong Kong lives or dies on waterproofing, and the basement renovation contractors in Hong Kong on this page range from a 169-review handyman platform to a small renovation firm with a perfect 5.0 across every review on file. Papabo leads on volume with 169 reviews at 4.9 stars, but its own reviews flag a real caveat worth reading closely before booking custom work.

Short answer: Papabo is the most-reviewed name on this page at 4.9 stars across 169 reviews, offering a broad handyman and renovation network across Hong Kong. For dedicated waterproofing materials, Wah Hing Construction Waterproof Materials (4.2, 18 reviews) has supplied the trade for decades, and a small Mong Kok renovation firm holds a perfect 5.0 across 5 reviews for full-service design-to-completion work.

English-friendly customer service, a genuine differentiator for non-Cantonese speakers
Follow-up adjustments handled at no extra charge, according to one reviewer

Worth knowing

One reviewer specifically warns against ordering custom furniture through the platform, describing poor material and execution quality despite the strong overall rating

What people praise

Decades of experience specifically in waterproofing materials
Wide stock of name-brand products including Sika, Fosroc and Mapei

Worth knowing

A couple of reviewers say prices weren't posted and ran higher than other shops nearby

What people praise

Perfect 5.0 rating across every review on file
Own dedicated team handles design through construction completion
Reviewers specifically praise transparent pricing and material quality
Craftsmen described as thorough, including cleanup after the job

Our take: A newer, small-scale option with strong early feedback on craftsmanship and transparent pricing. Worth a call for smaller renovation jobs, but ask for photos of comparable past work given the limited review history.

How we score

Every number on this page comes from public Google data on the date shown, not opinion or payment. Rating is the business’s live Google star average. Review volume shows how many customers have rated them, ranked against others offering renovation and waterproofing work in Hong Kong. Confidence weighs the rating by that volume, so a big base of reviews carries more weight than a handful. Recency reflects how recently people are still leaving reviews. No business can pay to change these numbers.

How much does basement renovation and waterproofing cost in Hong Kong? (2026)

None of the businesses on this page publish a fixed price list for renovation or waterproofing work, and job cost depends heavily on the size of the space, the extent of any existing damage, and whether the work is cosmetic or structural repair.

Serving Hong Kong

These contractors and suppliers serve homeowners across Hong Kong, from Kowloon districts like Mong Kok and Tsim Sha Tsui to the wider metro. Searching for a renovation or waterproofing contractor near me? Each listing below shows a live phone number so you can call directly and ask about your district.

What to ask before you hire a renovation or waterproofing contractor

Is the quote itemized, and does it separate materials from labour?
What brand of waterproofing product will be used, and is it suitable for below-grade or basement conditions?
How long is the workmanship guaranteed, and what happens if it fails within that window?
Will the same team handle design through to completion, or are subcontractors involved?
Can you provide photos or references from a comparable recent job?

Frequently asked questions

How did you choose these Hong Kong renovation contractors?

We started from businesses in Hong Kong with a public Google presence offering renovation, waterproofing or related construction work, then ranked by rating, review volume, consistency and recency. See How we score 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 often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Should I hire a handyman platform or a direct contractor for waterproofing work?

Both have a place. A platform like Papabo can move quickly for general repairs, but a direct materials supplier or specialist contractor gives you more visibility into exactly who is doing the work and what products are used.

What causes waterproofing failures in Hong Kong basements and below-grade spaces?

Common causes include substandard application, using the wrong product for the surface, and skipping proper surface preparation. Ask any contractor specifically what waterproofing system they plan to use and why.

The bottom line

Papabo is the biggest name here by review volume and a genuinely fast option for general handyman and repair work, though its own reviews suggest avoiding custom furniture orders. For dedicated waterproofing materials or full design-to-completion renovation, Wah Hing’s decades of supply experience and the small Mong Kok renovation firm’s perfect rating are both worth a call.
