Is there a tool that will allow me to...

... cut decking boards that are tight to a wall? In other words, my decking boards are in contact with my garage wall ABOVE the damp proof layer. It's a single-skin garage wall, and I've now noticed some damp coming through on the inside of the garage.

I therefore want to take about 10mm off the boards, all the way along the edge that butts up to the wall. Problem is, the decking boards have been nailed down with a nail gun (rather than screwed down) and are therefore a pain to get up. Just to be clear, the decking boards do not run parallel to the wall, they're perpendicular - i.e. I'd need to take up about 20 boards, not just one! Therefore need something that will let me get a cut really tight to the wall.

I thought that maybe there would be some sort of circular saw attachment I could get for an electric drill that might do it (like a bigger version of the circular saws for a dremmel), but can't seem to find one. Anyone got any bright ideas?

Many thanks

A biscuit jointer would get you part of the way but not the full depth, the type circular saws that run on tracks are reputed to cut close to edges there is cheap one on the market for less than £200 I think its called a woodster other than that its a nice sharp rip saw say at least 8 tpi and a sturdy pair of gloves

You could try onf of the multitools like the Bosch PMF 180

That said, i'm pretty sure my circular saw will let me cut down as little as 6mm off an edge. With saw fence butted up and running along the wall, i would have thought that would allow you to do it.
If you have nails where you want to cut the wood then maybe look at the evolution circular saw?

Screw a piece of 12-18mm timber to the end of the boards next to the wall as a guide and use a saw.

you also need to be aware cutting the ends back may not solve the problem as it may be splash back

the only sensible option is andys handsaw and spacer as any other option will cost you £50+

Fix some lead flashing to the wall.

You could always use a floorboard saw and a bit of elbow grease. Wouldn't take long.

Take a board up at the edge and infill with shingle to just below dpc, 10mm of the edge will achieve nothing.

Thanks All for the suggestions. I quite fancy buying a plunge saw, just to add another power tool to the collection. But might be a bit of overkill for what I'm trying to do!

Will check my circular saw to see how close it could get, otherwise use the hand-saw method with guide screwed along boards.

Will also use some lead flashing in case splashback still causes the problem.

Thanks again!

your circular saw will be between 25.4 and 38.1mm approximately

You can get wood cutting attachments for 115mm angle grinders on eBay. I have one, and it seems dangerous, but it's very handy from time to time.

Not a chance would you get me to hold that against a lump of wood

Hear! Hear! B-A has made a very valid point. An angle grinder isn't a circular saw; it runs way too fast for a saw blade, has limited guarding and no baseplate. You'd have to be completely mental to use on this way IMHO
