Working with a renovation contractor: what to confirm before signing.

A short checklist Ipoh and Klang Valley homeowners use to compare quotations on a level basis before locking in a contractor. Most disputes a few months into a renovation come back to one of these items not being clarified upfront.

We see this from both sides — sometimes as the original contractor, sometimes as the second one called in after a job has gone off the rails. The pattern is consistent. The seven items below are what we would check, in order, on any quotation we received as homeowners ourselves.

1. Are line items itemised, or just “allowance”?

The single most common red flag is a quotation that runs three pages of items but reduces to a column of round numbers, half of them labelled “allowance” or “PC sum”. An allowance is a promise to put in a number later, when it suits the contractor. By the time you find out the allowance for kitchen cabinetry was generous and the allowance for tiles was thin, the deposit is paid and the demolition has started.

Ask for supplier-quoted material costs. If the contractor cannot show you the supplier's quotation for the tiles or the cabinetry, they have not actually priced them yet.

2. Is the contingency a written percentage with defined scope?

Every renovation needs a contingency — site conditions are never exactly what the drawings show. But contingency should be a defined percentage (we use 5–8%) with a written scope of what it covers (unforeseen structural, unforeseen wet-area corrections, supplier price escalation beyond X%). Without that, “the contingency was used up” can mean anything.

3. What is the variation procedure?

If you change a finish or scope item mid-project, how does the price change get communicated? It should be: written variation notice, priced in writing, signed by both parties, then the work proceeds. Verbal variations and “we'll sort it at the end” never end well.

The contractor who tells you “don't worry, we'll work it out as we go” is preparing the ground for a final invoice that bears no relationship to the original quotation.

4. Who is your single point of contact?

You should know — by name, role and personal mobile number — who is on site every day, who you escalate to if they are not responsive, and who at the company owns the contract. Three names. If the structure is “Bos handles sales, then it gets passed to whoever is free,” assume the contract execution will be similarly hand-to-mouth.

5. What does the payment schedule look like?

A typical residential renovation payment schedule is 10% on signing, 30% at demolition completion, 30% at first fix, 20% at second fix, 10% on handover and snag clearance. Any contractor asking for >30% upfront is asking you to fund their working capital. Any contractor not asking for a deposit at all is unusual enough to ask why.

6. Insurance certificates, in your name?

Contractor's All-Risk and Public Liability insurance are standard for renovation works above RM50,000. The certificates of insurance should be issued naming the property owner as an interested party. Workmen's Compensation should also be in force for the contractor's site staff. Ask for copies before tools come on site, not after.

7. What is the defect liability period and what does it cover?

Standard in Malaysia is 12 months from handover, but the more important question is what it covers. Waterproofing failures? Joinery defects? Paint peeling? Get it in writing. A defect liability that excludes waterproofing is not really a defect liability at all in our climate.

Use the checklist to compare like with like

If you are taking quotations from three contractors, run all three through these seven points. You will quickly find that the cheapest quotation often becomes the most expensive once you adjust for missing items, allowances, and risk. The contractor who shows up with a tight, fully-itemised, insurance-and-warranty-backed quotation may not be the cheapest line at the bottom, but they will be the cheapest by the time the job is handed over.

If you want a candid second opinion on a quotation you are weighing up, send it across — we will read it and tell you what we would push back on, with no obligation.
