I had a deck built on one side up to my 24 foot above ground pool, they left a 5 inch gap between the deck and pool and i'm afraid my grandchildren will get their feet stuck. I've been using pool noodles but they fall down through. Help please.
When was the deck built and why was such a large gap left by the builder?
Does the decking run parallel or perpendicular to the pool?
It was built 3 years ago and he said he left the opening so we could get the winter cover on and off. The deck runs perpendicular.
Your major problem is going to be supporting the filler strip. With the deck material running perpendicular, your supports are then running parallel, something that is difficult to extend just a few inches. What you're going to have to do is "hang" the filler from the tips of the existing deck boards.
What I'd recommend is:
1 - Cut support blocks from pressure treated 2x6 that extend from the pool side support beam to within an inch or two of the pool side. Leave enough room to facilitate installing your pool cover.
2 - Screw through the support beam into the end of the 2x6 block and through the deck boards into the support block.
3 - Place the support blocks no more than 24" apart.
4 - Install a filler strip of decking parallel to the side of the pool, screwing into the support blocking you've just installed.
I would not worry about leaving space for installing the cover because you can easily remove the filler plank from the deck when it's time to install the winter cover.
Thank you so much will give it a try this weekend...
