ID vs contractor I think most reno-talkers struggle with this question. A considerable number of people no doubt spend ALOT of time meeting IDs and contractors. After reviewing a lot of experiences and accounts from reno-talkers, it's well known that ID is more expensive than contractor Economically, they must charge more than contractor since they are the additional project managers and designers and afterall must engage a contractor to do the work Some conservative estimates point to IDs charging about 30% mark-up from contractor based on these services. This is probably the accepted median It is not surprising if the mark-up is higher especially if the ID firm is big. They have bigger advertising budgets for TV/print/internet, bigger shopfronts and bigger exhibition booths i.e. bigger mark-ups, probably 50% upwards of contractor price. Also, all the big bosses in the ID firm who don't do projects and generate business need to be paid fat salaries Nonetheless, there are some contractors who are trying to go up the value chain and have ID services as well. No doubt they will charge ID type prices. I met a contractor like this. You know this immediately once the contractor offers 3D drawings, throws in freebies, has an in-house designer etc - all ID-like characteristics. Conversely, there are ID firms which are just starting out and growing their business. They tend to have lower margins in order to get volume and grow their portfolio. These will be cheaper and may be somewhat comparable to an average contractor pricing. However, they still need to pay a contractor to carry out all the reno so how do they manage to get comparable contractor pricing. There will probably be less people working on the wet works, tiling, demolitions, erecting walls, carpentry etc. Project may face delays because there is inadequate manpower to get the job done. Moreover, once everything completed, they won't entertain many rectification works. For me, it was a relatively simple decision. I wanted as cheap a reno to achieve the desired look/feel. Although I'm not a designer and have zero experience in reno, I knew the look that I wanted to achieve. There are very few IDs which can do industrial designs, simply because they turn to "standard" designs. This is to save effort and resource for them since they have done many projects in a certain look/feel. These are mostly modern contemporary. Having said that, choosing a contractor meant I needed to do ALOT more research on my own. I started to gather a lot of info about reno, the process, the materials and the rough pricing. To the point where people in the industry think I'm a contractor! If there are reno-talkers out there in a similar situation, I hope this will help you eliminate wasting time with meeting too many IDs and contractors.
