Deck questions


I have two questions about building a new deck. First, the ledger is 20' long. Can I use two 10" boards to create this 20" legder? I assume the answer is yes, but I'm just checking. Second question - can my pressure treated 2x8's span 6'.? They will be 16" on center. Thanks.

Hi,

Yes and yes. Tho I still believe in using 2x10's for any kind of deck joists. If you are going to use 2x10's as a ledger board (you wrote 10" boards)...why not use 2x10's for the joists instead of the 2x8's.....the additional costs are 'peanuts'. In either scenario...I recommend using 2x10's....

Also, PLEASE....make sure that you have done all your research on proper ledger attachment methods, fasteners, etc....

Realize as well, that I am only giving you ''preliminary suggestions'' based on a deck layout, home, yard/grading, etc ....that I cannot see. If there are other structural factors involved, then that's a whole other 'engineering' equation = even larger structural members may be required, footing enhancements, re-grading, drainage design, etc....

Lastly, please check first, on ....... any and .. ALL..... deck and code requirements in your particular locality....

Use the 2 by 8 why overbuild that is more than enough. Going pressure treated is a great thing to do. It will save you or the next owner of your home a lot of problems in the future.

Why would you use 2x10's for a 6' span?

We will use 2x8's for constructing simple landings, etc...

But we prefer to use 2x10's for anything that a customer plans on using as a 'deck'.
Why?, because people may plan on putting a few chairs out there (at first)....But what they end up using the deck for, can change over time.
Just one example; someone might decide that it's time to buy a small hot tub.....

Yes but as you well know it may not cost a lot to go from 2 by 8 to 2 by 10 but the cost adds up. When I built my house I had a million people say oh go this route it does not cost that much more. In the end I person needs to say enough. If a 2 by 8 meets all codes and you believe it fits your needs that is what you should use (In my opinion). If you try to plan to far in the future you could spend a fortune.

I build everything to code. Sometimes I frame a one story addition and use floor joists big enough to handle a second floor because a couple years down the road the people are definitely doing that. That's already on the plans.

You can't just over build for the , "What ifs". If that's the case building costs would sky rocket.

Besides, if you were to put a hot tub on that deck, the hole thing would have to be designed, not just the joists.

Yes

There are good points all around here but it really boils down to these questionss

What is the deck going to be used for, what will be on the deck, and what might happen in the future and finaly do I have enough budget to over build it in case I decide to ????. These are questions you must ask yourself before continuing.
I have always been in favor of over building (JUST IN CASE).

ummm, Yes..... ........but in this case we are talking about an extra $100.00 or less...(hardly a fortune)

Re-designed, yes, if you put a 6-10 person tub on it........but again, we are talking about bumping 2x8's up to 2x10's..about $100.00 or less...

(BTW- I just sawsome pics of a 2 person hot tub on a deck in the back of a house for sale....just this morning...house shopping on line)

Deck questions


My business partner, about 20 years ago, was on a small deck with a large group of friends, at rented cottage.
People were all over the cottage...eating and drinking.

At one point...everyone was called out to the deck for a 'group' picture taking. This took a few minutes.....guess what happened next....
25- 30 people...

Crash.........

Dont get me wrong, 2x8's will work fine, I am just offering '2 cents' based on the ''what if's'' of the future deck use...

Joe Carola, We tend to overbuild when it is cost effective.

Because of that, we have a very good reputation with all the building inspectors in our area, as well as with our clients.

Over-building does not mean that you ''up'' every single aspect of a construction project.

It can mean, simply, to bring certain 'key' structural areas/members up to the next set of 'inches' or design load strengths.... in the dimensional layout.

You figure that you are 'in there' already to do the work, so the labor is zero additional expense.

This absolutely has NEVER led to large extra costs for our projects at all.

When we do this, we inform our clients of what we are doing and why we are doing it. This leads to repeat work, word of mouth business, pride of workmanship, a good rep., and more.....that we feel is our personal company trademark and part of our reputation (We never spend a single dime to advertise, all our work is thru referrals and references).
