Before you engage a renovation contractor, there are some points that you need to do or take note.




Quotation

First you should locate a few contractors for assessment and comparison. Make sure that the specifications given to these contractors are the same. As different materials used can result in different quotes.

Assuming the specifications are the same, the quotes may still vary because of different standards in workmanship and service provided. It also depends on the time frame given to the contractor to finish the renovation work as the contractor may charge higher for more urgent jobs.

Never just go for the lowest quote. Assess carefully and cautiously the quotations, look out for any hidden cost, check if all the items discussed are quoted and included.



Renovation Contract

All requirements should be communicated clearly to your contractor. Never rely on verbal agreement, always sign a renovation agreement/contract. When you sign the renovation contract with your contractor, take extra note on the fine prints on the agreement.
