Unless the Lord builds the house, the builders labor in vain

Singapore Renovation Quotation Sample

Do you know the right questions to ask about the line items in your renovation quotation? What are the loopholes that the contractor or ID will exploit after you sign? I came across a Renotalk thread by “Mr Contractor”, a retired contractor sharing his experience. However, he is last heard in Jul 2014. So, can’t ask him anymore questions. 🙁 Anyway I’ve summarised his points for due diligence and some some other information I gleaned from elsewhere. Read on for a renovation quotation sample.

Finding Renovation Quotations


Confirming the quotation is the first major and most important decision made during the renovation. It is always tiring and time-consuming. It is best to compare the quotations from both ID and contractor to get a feel of what the price difference is like.

How many quotations to get? 

It depends on your personal preference. What Mr Contractor recommend is to get about 3 to 5 quotations to compare. Try not to go beyond 10 as it will make you confused over their suggestions on materials and design.

Different companies type out their quotations differently. For contractors, they will usually format it in a way which makes it hard for you to compare with the IDs.

When asking for quotation… Make sure all the quotations have about 85% similar items. This will make your comparison much easier.

Going through a Renovation Quotation


Contractors/IDs might try to play with words or leave out some details in the quotation, so that they can profit when they ask the customer to top up for the extra items. Below is a renovation quotation sample of a new HDB house with no hacking. The wordings in orange are Mr Contractor’s comments.

Renovation Quotation Sample: 

1. Supply labor & tiles to lay 641sqft homogeneous tiles for 3 bedrooms, Passageway, suggestion study, Living & Dining (Not more than $3.20 tiles)

641sqft x $8.00 per sqft = $5128.00

  • Does the $3.20 includes GST? i.e. If I choose a tile priced at $3.20 before GST, is it still within the quote?
  • Is 641 sqft fixed or okay for changes? (Usually there’s no change, but better to play safe.)
  • Size of the tiles? 60cm x 60cm or can go any bigger?
  • Are we able to choose tiles from any supplier or only specific ones? (tiles supplier give rebates to contractor)
  • If you choose a different kind of tile for another area, will there be extra charges?
  • Pre-packed screed included?
  • Extra: Sometimes the quotation gives you a price range for tile selection, e.g. you can choose tiles from $2.80-3.80. Check if there’s any rebate on the quoted price if in the end you choose tiles that’s lower than the maximum price. 
  • Extra: Contractors always encourage their prospective clients to use homogeneous tiles because of the higher profit margin. But of course, there are the pros and cons for each type of flooring. Choose one according to your needs. 

2. Supply labor & tiles to run 260ft homogeneous tiles skirting 3 bedrooms, Passageway, suggestion study, Living & Dining

Other useful Q&A

Lighting

1 lighting point refers to 1 down light, 1 ceiling light OR 1 track light. If you have a hanging lamp with 2 light bulbs, you will usually only need 1 lighting point. However, the electrician might charge you slightly higher than a ceiling/downlight installation, about $5-10 additional.

For small light sources such as those inside cabinets, it depends on whether you are using spotlight/downlight or tube/cove lighting. if cove lighting, one tube is NOT equal to one point. it is a looping point so sometimes they charge as a lump sum instead of per point based.

Plumbing

  • Is hot water piping work included?
  • Provide labour only to install 2 sets of bathroom & toilet accessories at 2 toilets: Clarify what they mean by set, and agree on the number of items and items on paper.
