Most renovation disputes in Macau are not caused by bad construction. They are caused by things that were never written down. Across the projects we handle, the same five patterns account for the large majority of client frustration — and every one of them is preventable at the quotation stage.
1. The lump-sum quotation
A price with no breakdown is not a quotation — it is an opening position. If the contractor cannot state the brand, model, specification, quantity and unit rate for each line item, you have no way to verify whether the price is fair, and no way to identify what has been substituted when a cheaper alternative is used on site.
What to insist on: itemised pricing for every trade — demolition, works, waterproofing, electrical, plumbing, air-conditioning, tiling, joinery, painting and finishes. State in the contract that no substitution without written client approval. Also agree a variation rate and a cap on total variations before the contract is signed.
2. Variations that nobody tracks
Once walls are opened, surprises appear: rotten substrate, outdated conduits, asbestos-cement boards that cannot be lawfully disturbed, structural elements that were not on the original drawing. This is normal in older Macau buildings. The problem is not the surprise itself, but whether there is a process for handling it.
What to insist on: a written variation procedure. Every variation should be quoted in writing with photographs, priced against the agreed rate, and approved by a named person before execution. Keep a running variation log. Without this, small changes accumulate into the "unexpected extra" that damages trust between contractor and client.
3. Hidden works that nobody inspected
Waterproofing, concealed pipework and buried electrical conduits are the three things you can never see again once the walls close. If they are not inspected at the right moment, a defect becomes someone else's problem — and in a rental context, a landlord's problem.
What to insist on: hold points that are written into the programme. Waterproofing should be flood-tested before tiling. Conduits and pipes should be photographed before closing. Ductwork should be pressure- and leak-tested before insulation. Ask for the photographic record as part of the handover pack, not as a favour.
4. Walls and ceilings that are not straight
Plaster can hide a great deal. But an out-of-plumb wall that has been tiled over cannot be corrected later, and a ceiling that is not level will show every daylight defect. In older buildings with significant settlement, this is a real risk, and it is far cheaper to address before finishes are applied.
What to insist on: tolerance specifications in the contract, and a pre-finish inspection of wall plumb, floor level and ceiling flatness. Specify the tolerance, not just the intent.
5. The warranty that exists only on paper
A handover certificate with a vague promise of "we will repair defects" is close to worthless. The question to ask is not whether a warranty exists, but whether the entity giving it still exists, and whether it can be contacted locally without involving a third country.
What to insist on: a written defects liability period with a stated response time and a named local contact. Confirm the company appears in the official Registered Contractor Query System of the DSSCU, and check its registration category and validity. A contractor that cannot be verified in the official register is not a contractor you should be giving your deposit to.
On deposits and online offers
There has been a visible increase in fraudulent social media pages offering renovation services in Macau, using stolen photographs of genuine projects. A common pattern is a very low quoted price, a request for a large material deposit, and a payment link or QR code that turns out to be a phishing page impersonating MPay or a bank. No legitimate contractor will ask for payment credentials, one-time verification codes, or payment through an unfamiliar link or QR code. Always insist on a written contract with the company's full registered name, commercial registration number and DSSCU registration number, and confirm the receiving bank account name matches the registered company name exactly.
How a properly run project looks
None of this is unusual or demanding. It is simply the difference between a project with a defined process and one without. As a DSSCU-registered construction works contractor (No. 7003/2024), we work to written programmes, documented hold points and itemised quotations on every project — and we are happy for clients to verify our registration directly on the official government register before they sign anything.
