How to Choose the Right Contractors for A&A Works

Related Articles

Choosing the right contractors for Alteration and Addition (A&A) projects is a critical decision that can make or break the success of your renovation. The task can be daunting given the significance of such a decision, particularly when dealing with complex A&A works. How can you be sure you are choosing a skilled A&A contractor in Singapore? This article will guide you through the selection process, ensuring you make an informed decision.

1. Research and Recommendations

Start by creating a shortlist of potential contractors. In addition to online searches and directories, consider asking for recommendations from friends, family, or professional acquaintances who have had similar work done.

Don’t ignore online reviews and testimonials that pop up, too! Take some time to read through these, as they can provide invaluable insight into the contractor’s reliability, work ethic, and quality of work.

2. Look at Previous Work

Before choosing a contractor, take a closer look at their past projects. Request a portfolio or case studies of similar A&A projects they have undertaken. This will give you an idea of the quality of their work and whether their style aligns with what you have in mind for your A&A works.

3. Get Multiple Estimates

It’s never wise to go with the first estimate you receive. Instead, aim to get at least three estimates from different contractors for a comprehensive view of the market rate. This will not only provide a basis for comparison but may also offer room for negotiation.

4. Check Credentials

An A&A contractor in Singapore should possess all the licences and accreditations required by local authorities. A professional contractor will also be more than willing to share accreditations and certifications that affirm their competence. Failure to properly vet could result in subpar work and legal complications.

5. Ask About Timelines

Get a clear picture of how long the A&A project is expected to take. Although timelines can be subject to change due to unforeseen circumstances, a professional contractor should be able to give you a realistic timeframe for completion. Ask each contractor about the projected timeline for your A&A works and how they plan to adhere to it. Delays can result in additional costs, so your contractor must be realistic and reliable in their time estimates.

6. Discuss the Budget

Be transparent about your budget from the get-go to avoid any misunderstandings later. Make sure to discuss the budget in detail, covering not just the costs of materials and labour but also any contingencies for unforeseen expenses. A reputable contractor will be forthright about what can be achieved within your budget and will make appropriate recommendations to ensure quality and functionality.

7. Evaluate Contracts and Warranties

Once you’ve chosen, ensure that all aspects of the job—scope, timeline, costs, and warranties—are clearly outlined in a written contract.  If anything is unclear or missing, don’t hesitate to ask for clarification or amendments. This will protect both parties in the event of disagreements or disputes.


Choosing the right contractor for A&A works is a crucial aspect that requires careful planning, diligent research, and thoughtful consideration. Following these guidelines will help you make an informed decision, ensuring the success of your project whenever you’re dealing with an A&A contractor.
