There is no way for us to tell you this. These are all different trades and a contractor for sure will not upholster chairs. You need to reach out to each of these trades separately to get a handle on pricing unless what you are asking is the cost of a general contractor who will sub out all this work except the upholstery which will probably require a designer

Thanks for your responses. It is definitely very helpful.

I reached out to different people for the different types of work to get a quote. For the upholstery service I was quoted $260/chair (before tax). I just wasn't sure if that was considered average.

For the installation of marble flooring I was quoted $8.80/sq ft, which again I wasn't sure whether the price was considered average.

I've reached out to multiple places to see if the cost for these services will come back relatively the same. I'll wait and see what they all come back with.

It's admirable that you have tried this forum to enlarge your research; however, I'd guess that many of us here have not been and will never be in Toronto. Heck, I've never even been to Canada! You are asking very location-specific questions on a worldwide forum. Good luck.

Please remember that not only is the price location-specific as littlebug points out, it is dictated by the size of the chair (for example) and the design you choose. eg: with welting or without, loose cushions vs firm back, nail head trim or not....I'm giving very broad strokes on just one chair. The labor cost would vary with each of these upholstery treatments.

Installation of marble would be another whole can of worms. Why would you want an average installation with all of it's flaws when you can get top of the line installation? Take a look at the posts showing terrible installation by a sub-contractor that claimed they knew what they were doing.

I understand the importance of knowing costs but it appears your assignment is to find out that there is no such thing as average costs in the real world. You need to spec out each job and get quotes from multiple vendors in a variety of price points. You will see that no subcontractor bills himself as the guy who does an 'average job' for an 'average cost'. JMO.

Thanks, Denita. I did provide the size of the chair to get the price. As for the marble floors, I’ve seen terrible jobs done. So for that quote, Home Depot was one of the places I reached out to as I figured they’d have more reputable people they use and was going to see how others compared. I’m not looking for average work, just trying to make sure the prices I’m being provided aren’t outlandish.

Home Depot doesn't necessarily have more reputable people to do installation. Do some research and you will see some terrible reviews of HD installs. HD is no guarantee of good work by any means. In fact, I prefer to work with someone not affiliated with HD or Lowes or any big box store because then I know I'm not paying for the big box store's cut. I'm getting pricing from the actual vendor doing the installation - better warranty work, better quality work and a direct contact without going through the HD/Lowes/big box maze.

This is very helpful. I will definitely take a look. Thanks for your insight! It’s greatly appreciated.

OK...so the average TILE installation in Vancouver BC (quite comparable to T.O.) is $10/sf. Stone install will be more. Like $1.50 - $2/sf MORE.

The $8.80/sf from Home Depot is the "Holy Cow! What happened? Who let these people in here? OMG! Now I have to do it again!" type of stone tile install price.

For stone, I would budget $10 - $12/sf for labour. The price of the materials will be added to that quote. Please work with HIGH END stone installers. Toronto has a wonderfully diverse ethnic community with a wealth of "Old World" talent that came with them when the immigrated. Feel free to reach out to the communities that are known for MARBLE...ahem...Italian marble being the most desirable in the world (wink wink nudge nudge say no more say no more).

The chair upholstering could be low...or it could be accurate. It depends if the MATERIAL is included in the price.

The stucco and painting work is another project that can often be dealt with by a single company. Go ahead and look up interior paint/drywall specialists...there are plenty of companies that combine these two specialties.

I know that drywalling/mudding on a new build can be as much as $5/sf. That's for the TOP end job (with floating the walls with multiple coats). You could be looking at $2/sf depending on the actual job.

Have you tested for Asbestos/lead?

You're an angel! Thank you so much for this - I really do appreciate your time and help!

I will update my budget to reflect high end work instead of the quote provided by Home Depot. And I know what you mean about the Italian marble, lolll! Say no more, haha! Toronto is definitely a melting pot of culture, so I will take your advice in searching for the creme de la creme (especially when it comes to doing the necessary work - the right way, the first time!).

I will look into testing for asbestos/lead. Definitely important!

There's a quick way to assess whether or not you *need to test for asbestos and lead: the AGE of the home will point you in the direction you need to go.

High-level lead based paint STOPPED being produced in 1978. I would assume it was used until 1980 (to make a nice round number). If the home is OLDER than 1980, then you will want to have the painted surfaces investigated.

As for asbestos, it was no longer PROCESSED for sale in N. America in 1982. But the companies that had materials made were allowed to sell off their products until the mid/late 1980's. Again, if the home is older than 1985, you will want to have some of the surfaces checked for asbestos as well.

But the closer to those "dead lines" the home is, the LESS LIKELY you are to find asbestos/lead. If you can keep the number 1980 in your head, you should be fine to make the appropriate decisions.

Good luck. Glad to help point in the "right" direction.
