Roughly how much would a 12' x 35' (420 sq/ft) plain rectangle deck cost to get built, with 4' deep concrete footing piers?

I roughly priced the materials alone at about $1500.

isn't 2x the cost of materials normal for labor?

more details needed.

height, steps, pt or syn decking, rails, ect. pic of site would help.

I just built a 14x23 deck - plain rectangle, 8 concrete piers total. Materials cost was $2500 and that was using all pressure treated lumber. I think you may have under-estimated :)

plus, if you buy your wood from menards, its alread pre-warped, so you can have a nice, flowing design....

Decking height will be 3 feet.
PT decking and railing.
Simple steps on each end of the deck.

I am building a 15x20 right now. I got a couple quotes before I decided to save the cash and do it myself. One quote for 11k and another for 12.5k. My materials are going to cost in total around 5.5k - 6k. I am using PVC decking so my numbers are higher than if you just do pressure treated decking. So it seems to me that installed a deck costs about 2x materials.

I agree. I'm almost done with a 10'x40' deck, rectangle with a 2'x14' rectangle taken out of one side where the kitchen over hangs the foundation, pressure treated lumber, 8 footers, steps on both ends, and on sloping ground so that one end is about 3' above grade and the other is about 6' above grade. I've probably got close to $2500 in it so far, maybe more.

(85) 5/4x6 x12' decking = $500
(3) 2x10 x12' ledger = $50
(33) 2x10 x12' joists + ledger = $500
(6) 2x10 x16' beam (2-2x10) = $130
(2) 6x6 x 10' posts = $80
6 footings (7' apart, 10' out) = $200 ?

$1420

I didn't count fasteners and railings/stairs/flashing yet. Yeah I guess another $500?

Did you guess lumber costs or did you get actual prices from a local lumber place? Not an expert by any means but the decking costs a little low.

Yeah, also, add in joist hangers if you're using them, nails, screws, railing/posts, and stain at a minimum....

Actual cost rounded.

A long time ago when I did residential irrigation we'd add up whatever materials were and charge 3x. So if materials were $5,000 total job was $15,000 and out of that we paid labor, machine rental, etc and the rest was profit.

I think that's pretty standard.

6809.26 is builder cost, figure retail being 1.2 to 1.5 times that from a small reputable contractor.

Thats 5/4 treated decking nailed
2x10 joists cantilevered over a 2x10 beam
max of 4 steps on either end
all pt lumber
permits and inspections
trash removal
materials and delivery
fuel allowance
labor and payroll and insurance
1/2" lags & bolts, hangers, vinyl flashing
2x6 top handrail and 2x2 spindles
4x4 rail posts, 6x6 deck posts
16"x36" footers in a sonotube with galv anchors.


12x32' would be slightly more economical to build.

If you just charge a multiple of the material, wouldn't the labor charge be overinflated for more expensive materials?

If you miscut a piece of vinyl or it breaks or you gouge it, its more expensive to replace. Typically more difficult or involved to work with too.

There is a major difference between the install of pt railing and endurance railings. Miscut a 8' pt 2x4 and you are out 5 bux, miscut a 8' endurance top rail and you are out $300. 5/4 pt decking is light and easy to nail, trex is heavy and should be screwed, major difference in labor.

Sounds pretty good. I was thinking about $8500.00-$9K retail.

10" x 42" Piers, though.
