Default dock replacement

Curious what people have paid recently for a 6x40 crank up dock? It's a replacement - the pad and anchor for the crank is in place. I've got some calls in to different people and am wondering what, even ballpark, people are paying. Nothing is inexpensive these days!

Not exactly relevant, but we just had Watermark do a 9' extension to our crank up dock. 6' wide, azek decking, aluminum frame. That was $7500, including installation. Maybe multiply that by 4.5 to get you "in the ballpark"? (Side note: they charged us $13K for the 6 X 40 crank up dock new in 2013).

Thank you. Did the $13 include the concrete pad on the shore to anchor the dock and the pd to anchor the crank? It's helpful to see that today's 9' extension is double the price of the 2013 dock.

If you want to do some of the work yourself, I just used someone for the aluminum dock frame but just to build the aluminum sections.

It is two sections 6 X 27 bolted together to make a 12 X 27 dock. The sections were a little heavy to carry so a friend with a loader took them off the trailer at the street and brought them down to the water.

I attached the posts and put the decking on myself. The aluminum work was excellent. My recollection is the cost of the aluminum was about $10,000.

Lowes delivered the Trex to the house and the cost with the necessary fasteners was about $1,450.

The dock is sitting on a breakwater so it will be permanent but could have been hinged. The bottoms of the posts are currently about 8 inches above the water so I am hoping the ice won't be a factor.

Yes, the $13K included everything. Concrete pad at the shore that the dock frame is attached to; azek decking; 4X4 posts; winch pole and cabling; the sleeve in the ground that the winch pole sits in during the fall/winter; installation.

Ever any issues with the composite getting too hot to walk on with bare feet if in direct sun for long exposures? I know some of the stuff out there gets super hot and some not so much.

The color you select will be a determining factor in how hot it gets. Darker colors such as brown will certainly get a lot hotter than the lighter colors.

My current decks at my place are a product called “Lumberock”. It is made of a solid blend of high density polyethylene (HDPE) and completely non organic. The color is either tan or cedar (don’t remember) and I have no heat issues with it. It is actually quite cooler than my previous PT deck. I absolutely love the product!

Our dock decking is a light gray azek. We purposely chose a light color to mitigate the heat retention, as it is in full sun all day (on a sunny day of course). I would say there are maybe a couple times per year that it gets really hot, to the point that you say "ow" when you first step on it. On those occasions, we just splash some water on it and problem solved. The maintenance-free, splinter-free qualities of the azek far outweigh the heat retention, in my view.

We had the "old" Trex and it was awful on your feet. I hear it's better now though. We have Azek now and it's never been a problem.

Dan (ishoot) and I have Lumberock on our different decks—his on his docks, as well—and it's totally fine on the feet in sun.

All the tests we have seen.
It is a trade off.

Material density, color, and engineered heat mitigation seems to be the main variables.

I have once price of $20,000 for a 6x50 crank up aluminum dock, installed and removal and disposal of the existing dock. Decking quoted is pressure treated. Second quote is higher; waiting on third.

Shocked how expensive things are!

That sounds reasonable, that's a big dock.

I have two recent quotes for a 6x40' aluminum crank-up, including pouring the foundation and using pressure treated decking. This is on an island.
about $25k and
about $30k

Question Do-it-yourself hinge dock?

Craigslist boats; someone in Laconia has a 6' x 24' aluminum truss frame for a hinge dock for sale for five hundred dollars. Has four good photos. Says made in year-2000.

Need to build a shoreline concrete base with hardware to fit the hinge on the frame.

Thanks. $20k seems in the ballpark since I don’t need cement work.

Yes it is very shocking how expensive things continue to get....
Just for some comparison I took a look to see how expensive hardware from RDS is....

to do a pipe dock, 40' long you start with 1 4 leg kit ($927) and then 4 more 2 leg kits ($464 each), which gets you out to ~2.8K, which doesn't include the pipe for the legs so 12 legs at 60$ per (assuming all 8ft, so this cost is likely less, but this makes it easier) for 720, and lets say anoth $500 for cross bracing... so where are we now, at about 4K just for new hardware....

Now add in the needed wood, for the frames and and decking etc. and your likely looking at 7K to build your own dock....

Still in a very high demand cycle.
I keep track of license plates to let me know when we have a problem, and we still don't seem to be seeing less.
