A 15 x 20 inch deck should be fairly cheap. Would not even use 1 complete board. Is it for a dollhouse?

I got quotes for a 20x14ft deck and the prices ranged from $4000-$5500. I was told directly that 40% of the cost of a deck is materials and 60% is labour.

That was a bit too steep for me.. so I built the deck myself, a 20x12ft deck for $2000 total (materials & my labour).

I just built a 12x12 deck for $700 using pressure treated, but I did the labout myself. Double that price if it's cedar.

. . .and quadruple that price if you use trex composite.

price will also vary depending on whether you build a floating deck on blocks (cheaper) or drop postholes, sonotube, cement in your deck posts (more expensive)

also, elevation of the deck may cause some slight differences to cost, and may require building a short set of stairs--at a certain height, i believe you also will be required to add handrails, etc.

Yeah, we dug 3 foot holes and poured concrete. Hard work, but the deck will stay level longer. Didn't bother with the tubes though. Cement isn't much more expensive though. Average bag is around $3.50. We needed 2 per hole, and a deck block is around $6. It isn't as easy to do of course.

Slightly off topic - are you required to get a building permit for a deck?

some municipalities require it (e.g. milton, kanata) some don't. You need to find out the local bylaws

u need permits for just about anything you do these days,,,,,, but most people building themselves don't bother,,,, but at the least make sure you are building it to code.

I am not skilled to build my own deck and I'm looking to build a low level deck 6-8" above the ground. I recently found a screen house at Costco 13 x 15' with metal roof and sliding screen doors for $1599. The screen house requires the base to be screwed into footings or some strong material to prevent wind removal. My idea is to have a 15 X20' deck for the purpose of securing the screen house. I need to know the price of materials, labor and stain .
