Frequently asked questions
IES/SPROJM certification matters because you want inspectors who understand Singapore properties, not just general building standards. It shows local construction knowledge and familiarity with HDB, BCA, and PUB requirements. With Ark Interior, you get a team with 25+ years of local experience, so you can catch issues that matter here and receive more practical advice for your home.
Renovating your landed home can do more than refresh the look. It can improve how you live, make better use of your space, and add features that fit your family’s needs. You can also upgrade older systems and choose energy-efficient options that may help lower long-term costs. When planned well, it can also support your property’s value.
Before you start, you should set a clear budget, decide on your timeline, and outline the design you want. You also need to check the relevant building rules and approvals for your property. Working with an experienced team helps you avoid delays and keeps your project moving in the right direction from the start.
During a defect inspection, you may find water seepage, wall cracks, uneven finishes, electrical faults, plumbing issues, and other workmanship defects. Catching these early helps you follow up with the right parties before small issues become bigger repair costs. It also gives you a clearer picture of your property’s condition from day one.
You should book your defect inspection as soon as you collect your keys. For HDB properties, defects should be reported within 14 days, and your 12-month Defects Liability Period (DLP) gives you a limited window to raise issues. Booking early helps you document problems before any renovation starts. We can also coordinate with your utilities turn-on date to make the process smoother.
Free inspections from IDs or agents often come with conflicts of interest—they may downplay defects to speed up renovations. At Ark Interior, our independent, IES-certified engineers focus solely on your property’s safety, not sales commissions. Plus, our detailed reports are court-admissible, giving you peace of mind in any disputes.
At Ark Interior, we go the extra mile with our post-inspection support. Here’s what you can expect:
- Lifetime WhatsApp support for all your defect-related questions.
- Free re-scans after rectifications (available with selected packages).
- Renovation-ready insights from our in-house interior design team.
Unlike competitors, we include these services at no extra cost!
