We’re in the process of building a new home with what I’ll call a “high-end track builder”. They aren’t a DR Horton or a DSLD but utilize a track system regarding selections.

So far they have been decent to work with, with the exception of a few minor changes that they wouldnt work with us on. Build quality to date seems to be good.

As you can imagine, with any change request they hammer you with an egregious change order that’s marked up to hell and back. I’ve been fine with these as it’s minor upgrades that don’t amount to a ton and allows us to wrap it into the mortgage.

To my question. The home sits on a slope and will require egress off the back porch (built into home). They claim their only plan was to provide railing and a set of steps off the porch. Which I feel is bullshite for the type of home we’re building, but that’s on me for not negotiating prior to going under contract.

We requested pricing to have a roughly 120 sqft deck built off the porch. They came back with a price of $25k. It is trex composite material with rope wire style railing, privacy slats below and gate access to under the deck.

I feel this pricing is extremely steep, entire home was built for $250/sqft. Steps and one railing was already planned to be included due to them having to provide some sort of egress.

TL;DR

Received price of $25k to have a 120sqft deck installed. Is this high?

if everyone here says yes, how does that help you get your deck built?

No idea. Get a quote from a couple other companies and see what they come back at. If it’s in the ballpark, you might as well have the builder do it so it will be done when the house is done.

Use this to get a cost of material estimate. If it's half or more of the 25K I would think they are giving you an OK price. You can even request a quote from them on that site. They do ask for your email to send you the material cost calculation.

They won’t provide plans, claim it’s proprietary.

I could be off base on the cost to build a deck and I accept the price? Or someone with better info than me says it’s high as hell and I decide to handle it with another contractor.

not trying to be a dick but you should be aware of a few things, in the interest of gathering info. your deck is worth what someone in your area, with the time and expertise, is willing to build it for. just because the materials cost $X.XX and labor is $X.XX per hour doesn't really help you unless you decide to build it yourself. the contractor who is already on site gave you a price which requires you to do nothing in order to enjoy a new deck, plus i assume you can roll the cost into your loan. if you want to go get quotes on it, that's your right but you already know that's going to cost you time and aggravation, plus you may not get a better price (or an equal quality deck).

there is a fallacy among project owners that additive change orders are desirable for contractors...they are not. deductive change orders however are welcome at any time

good luck. if i were you i'd discuss options to lower the cost of the deck with the contractor you already have, if $25K is too much

Your home plans aren’t part of your contract?

They had to submit plans to the building department. See if you can get a copy from them.

When I priced up using weathershield it ended up being close to $25 a square foot just for the material and fasteners. That's not including closer deck joist spacing. Mine's only a foot or so off the ground. At most. It would have been cheaper to put down concrete and travertine pavers down so I opted for wood decking. It's really hard to tell you that that price is high considering we don't know any of the details of how high the deck is, how long it is and wide. Foundations can run up a price. Hope that helps.

The deck is 8’ x 16’, approximately 4’ off ground on the edge that ties into the back porch and 6’ off ground on the opposite edge.

So 8 ft ft out and 16 ft along the house? And are you in the BR area?

I'm only asking for foundation details that would be needed.

Quality handrails and steps are time consuming and pretty expensive if they're done correctly with workmanship.

Seems steep for trex. I would want the materials list. The base boards are like $15 bucks.

For 25k I think you are more in the lines of a PVC board with a full aluminum railing and spindles.

From my experience, I wouldn't want framers building and GCs finishing a deck. They always seem to look like shite

Framers and the GC will probably skip a whole bunch of important steps like using .80 for the framing and using a mastic tape on all joists and hangers. Folding joints on Trex and the such is an art form.

Deck will be supported by 6x6/4x6 posts. Handrails are wire rope with a trex top cap. There will be privacy slats installed below with a gate to access under deck.

I would say it's probably a $19,000 job. They probably threw money at it so they could sub it out to a deck guy and make six or $7,000. Good luck.
