I'm having an argument with my husband. Do you think it's better to build a deck for the back of your house (attached) from scratch or better to purchase a pre-made kit ? What are the pros and cons ?
Our house has 2 large decks and neither is attached to the house itself. We built on an addition and it was easy to plan the framing to add the decks but my preference is to have the deck separate from the house. You have to install more posts and footings, true, but you should never have to worry about the house sheathing and framing being exposed to weathering and rot. No matter how good a job you do with flashing and sheathing down the road, you will have problems.
My wife went to the local lumberyard and they picked out the lumber for the 12X16 deck, what they sent was so warped and waney and knot holed I sent half of it back. If you buy a pre-made kit you can be sure a majority of the lumber they pick out will be poor quality. I bult a second 12X24 deck and hand picked every single post, joist, and deck board and all of them were excellent quality. By doing it myself I was able to add additional support posts and far, far exceeded the code requirements and 6 years later, the bigger deck is still perfectly square and level and retains stain well. The lousy deck boards the lumberyard sent us will not hold stain worth a darn.
And while I am on the subject, if you have to have railings, forget about those wood railings that use the square spindles. Go with PVC railings. When it comes time to clean and sand and restain the deck, the wood railings will require more time and work than the rest of the deck combined. They are the biggest headache in maintaining a deck...for what it's worth, I am a retired jack of all trades carpenter with 36 years of experience.
