deck boards too tight. Can I saw inbetween????

18 years ago

I'm hoping to get a few more years on my pressure treated deck before replacing the boards. A good number of the boards were either nailed very close or have expanded so that water doesn't drain between them very well. Should I set my circular saw deep enough so not to cut the support beams and run them between the deck boards to reestablish an opening for drainage? Or am I wasting my time? OF course, I would use the correct PPE to avoid the hazardous wood dust.

If you have a Circular saw and are good with it, no problem cutting straight free hand. Don't waste your time with guides. Will attach a picture of before and after. Safety first, set saw depth to not hit joists, make sure no wiring running below that could hit, wear knee pads, Sand so you have a good edge to follow, practice in an area not front and center. If you have a railing you won't be able to go all the way with circular saw, at which point either leave it or hand saw it. Very happy with how mine turned out. Not sure why these contractors are building decks like floors but it's not good. Water damage and no where for debris to go. Don't put up with it. Fix what they did wrong!

I wouldn't worry about it unless it really bothers you. Just make sure you verify the board thickness first before you cut. If it's 5/4 board set your blade at 1 1/16". If 2x set blade at 1 9/16". DO NOT CUT INTO YOUR JOISTS.

I also would not bother, if at all possible. If you run a saw between the boards, you might be removing the treated portion of the edge of your deckboards. It depends on how well the chemicals penetrated the edges of the boards.

You could do it with a circular saw, but you may need 2 passes to create a sufficient gap. Another way to deal with the problem is by drilling a series of 3/8 or 1/2" holes. I had an old pressure treated deck with the same problem. I waited until after a good rain, and drilled holes where necessary. The problem was caused by a big maple tree dropping lots of tree trash...flowers/seeds/leaves.

What are the chances of make a straight cut along the deck board? Not very good. I think it would look very amaturish.
dooer,
if the chemical didn't penetrate more than the width of a saw blade I would suspect that the decking would be in pretty bad shape by now.

when you do replace the boards, this time keep at least 1/4" between them to prevent teh same thing again!

1/4" gaps? That's wrong!
If you set 1/4" gaps on wet pressure treated wood, you'll end up falling thru those gaps when the decking shrinks.

I know of a Circular attachment that will allow for widening the space between deck boards.

Watch this video about the Saw Guide from Lounsbury Products.

I think the question still gets asked. The only reason I posted twice is because the video address has changed. How did you notice a new posting on a 9 year old thread?

Bob freehand is great for folks that are good with a circular saw. To make precise smooth cuts along the side of a deck board nothing is easier than the Saw Guide from Lounsbury Products.

It really doesn't take much skill, follow your eyesight guide and saw tends to keep it straight. I have looked at that guide and feel most who own a skill saw have the skill to do this. And if your a little off center from time to time no big deal. It's not a church and the ones who notice and say something, well offer your saw to them!!
