| Dear Ms. Builder: I plan to start building my first deck soon. I
want my deck to look unique, but I am not an experienced do-it-yourselfer. What
is best for someone like me? Any basic deck building tips? - Mary W.
Dear Mary: I have built some elaborate unique decks over the years,
but these designs are beyond the abilities of a first-time deck builder. My
first deck was a simple rectangular design with one set of stairs and a bench.
Instead of trying to build a deck beyond your skill level, use several types
of wood to give it a unique look. It is actually easier to build with a wood
like redwood than with pressure-treated pine. Using a lot of redwood can make
your deck look spectacular.
Redwood is lighter and easier to handle than pressure-treated lumber. It is
also easier to saw. Although it is not good to inhale any sawdust, sawdust from
redwood is less hazardous than from pressure-treated lumber. You can safely
burn small scraps of redwood in your fireplace.
You should still use pressure-treated lumber for all the structural members
- ledger boards, beams, joists, etc. Just use the redwood for the railing, deck
area, benches and accessories.
The only drawback to redwood is its higher cost, but you can minimize the
cost differential by selecting the proper grade. There are many grades of
redwood that are attractive and durable, yet cost less than clear all heart
redwood.
In order to get the decay and insect resistance of redwood, you must select
one of the heartwood grades. The naturally-occurring resistant chemicals are
concentrated in the heartwood.
I have used a lesser construction heartwood grade of redwood. It has tiny
knots that are attractive and do not harm its effectiveness. The materials
needed to build a 12 ft. square deck with this grade of redwood cost only about
$200 more than using all pressure-treated lumber.
It is best to spend a little extra for stainless steel nails for any deck,
but especially when using redwood. Stainless steel nails eliminate future
unsightly stains. Hot-dipped galvanized nails are a less expensive option, but
you still may get some rust and staining.
Cut all your redwood pieces and lightly tack them together to make sure they
fit. Pull the pieces apart again and apply sealer on all the surfaces,
especially heavy on the cut ends. If you make even minor final fit cuts, make
sure to seal the ends. It pays off long-term.
Tip #1 - Plan, plan, plan. Unless your budget is totally unlimited, layout
and plan your deck to minimize excessive scrap material. Layout your deck
furniture, barbecue, planters, etc. in your yard first. You will be surprised
at how big the deck must be.
Tip #2 - The first construction step is to attach the ledger board to your
house. This requires cutting away some siding. A circular saw, set to the
proper depth, works great on wood. Cut slowly and move backwards when cutting
aluminum siding.
Tip #3 - Although not required, it is a good idea to space the ledger board
out from the house about one-half inch. This allows for drainage and air
circulation. Use a couple of large washers for spacers.
Tip #4 - When you predrill the ledger board for the joist hangers, shoot a
blob of caulk into each hole. This seals out moisture during construction. Also
use the caulk on top of the ledger board for the flashing.
Tip #5 - When you get ready to cut off the top of the posts, mark the level
line on all four sides. Make a cut on each side of the post and finish cutting
through the center with a hand saw.
Tools and materials required: Claw hammer, chisel, nylon string, circular
and hand saws, shovel, post hole digger, pry bar, cordless drill, level,
lumber, stainless steel nails, joist hangers, wood sealer, concrete, bolts.
