I've been calling around for pricing and I'm getting numbers anywhere from $20/sqft to $45/sqft... any idea on why such a large variation in pricing between contractors?

When I went to Home Depot to get an idea of what material would cost, it was looking like a capped trex select for 300sqft would be around $6,000 or $20/sqft, so what would be a fair amount to be paying in labor?

To clarify, the deck wouldn't be more then 1.5feet above the ground and at this point we're not asking for anything fancy (no rails, fancy cuts, etc...)

I would go with the middle of the road quote. There are large variances contractors will charge for the skill level if you go cheap on labor it will reflect in the work being done. $30 I sq foot is not unreasonable.

The $20 a soft sounds about right but normally contractor's would charge double the cost of materials to make there money I have seen it time and time again I personally think it's wrong we don't charge by the Swift it normally a flat rate. To be fair with the customer that's why we are so busy.

It depends on a few factors is access easy , is it attached to the house, are you installing proper posts, need a permit I your area?

If your spending the money for composite I would think you want a good job

Check reference go see decks he had done

45$ sq ft is on the high side.

Are you sure the quote for 45$ was just for labour?

I charge 45% material cost 55% labour cost for most decks. In Ontario anything over 100 sq ft requires a permit usually an extra $1000.

BTW, it's a corner lot so there's side access... The quotes I'm getting are including material. Should I be paying more for labor if it's composite?

Most companies like ourselves do not price out jobs per hour, they provide an all in inclusive amount. The reason being allot of medium companies are the only reputable companies that would take on this kind of job. A bigger company like Oakwood for example wouldn't take on this kind of job because the project is too small and companies overhead is too big to take on such a small job. This is leaving you with a small to medium sized renovation company or a father and son company, or a handyman type of renovator.

But even small & medium sized renovation companies have overhead. They need to pay for an office, administrative staff like myself who follows up with leads, books appointments & so forth, an accountant, estimators, carpenters & you need to pay for WSIB which is very expensive, payroll, a medium sized company on a weekly basis is spending over $20,000.00 paying for staff & various sub trades. That's not including rent, internet, advertisement, softwares needed for the office & so forth. I think the prices you have listed are very reasonable especially if there offering a warranty. Most companies like ourselves offer a 2 to 5 year warranty where some joe shmoe can't do that.

You usually get management taking care of the whole project for you, submitting city permits and so forth. So in my opinion I would say this is the average cost to build a deck. I hope I was helpful!

Hi Adil,

As you can see in the replies, The price ranges from 20 to 40 depending on difficulty.For the deck you are describing low to mid 20's for labor is a reasonable price, especially as you are not doing any railings or steps.Many times i recommend to my customers to get pressure treated and then we offer a 10 year maintenance contract which includes pressure washing and staining every two years. Even with the 10 year contract which you pay over 5 years the cost comes under the 42 to 47 dollar mark per foot, and you always have a brand new deck.

Hope this helps in making your decision.

Different composites come with different costs. We break our estimates in sections for ease of budgeting. Stairs, railings, skirting and structure all are separate lines on the estimate. For Trex Select, just substructure would run you about $30/st ft. That price includes footings, framing and decking. Hidden fasteners, angled decking, picture framing or inlays are available for additional cost.
