How to Choose a Reliable Renovation Contractor
The contractor you pick matters more than any single material choice. Here is how to tell a dependable one from a risky one.
A renovation lives or dies on the person running it. Great materials fitted badly still look bad, and the horror stories almost always trace back to a contractor who was never properly checked. Here is how I vet one.
Check they are real and registered
Anyone can print a name card. Before money changes hands, confirm the business actually exists and has a track record you can see.
- Verify an SSM-registered business name and company details
- Ask for a portfolio of completed jobs — ideally similar to yours
- Ask to speak to past clients, and if possible visit a finished unit
- Check they are contactable through a proper business line, not only a disappearing chat
Compare quotes like-for-like, not just by price
The cheapest quote is rarely the cheapest job. Get at least three written quotes and read what is — and is not — included.
| Green flag | Red flag |
|---|---|
| Itemised scope, materials and brands listed | One lump-sum figure with no breakdown |
| Clear timeline and payment stages | Large deposit demanded upfront |
| Answers questions patiently | Pressures you to sign today |
| Prices variations in writing | ‘We settle extras later’ |
Put everything in a written contract
A good contractor has no problem putting things in writing. This single document protects both sides.
- Full scope, materials, brand/grade and finishes
- A timeline with start and completion dates
- Staged progress payments tied to completed work, not a big upfront lump sum
- A retention held until defects are fixed, and a defects-liability period

Frequently asked questions
How many quotes should I get?
At least three, on a like-for-like scope. That gives you a real sense of the market rate and shows which quotes have quietly left items out.
Is the cheapest contractor a bad idea?
Not automatically, but a price well below the others usually means something was excluded, to reappear later as a costly variation. Compare what is included, not just the total.
How should I pay a renovation contractor?
In stages tied to completed work, starting with a reasonable deposit, with a small retention held until defects are fixed. Avoid paying most of it upfront.
