Denray Posted April 21, 2013 Report Share Posted April 21, 2013 This house has poor quality composite siding. Built in 92. Starting to show deterioration at bottom edges due to lack of meticulous maintenance. So what needs to be done about it? Can those areas, which seem small now, just be sealed up well?

Marc Posted April 21, 2013 Report Share Posted April 21, 2013 Not with a wood composite siding. I'd just say that it's a lousy choice of siding and that there's signs of failure. Eventually you'll want to replace it a panel at a time if it can be matched otherwise a wall at a time. My report wouldn't recommend replacement now unless it's extensive, over a door/window or there's signs moisture intrusion inside the house.

gtblum Posted April 21, 2013 Report Share Posted April 21, 2013 I would seal that up, add a piece of chamfer strip to the entire length at the bottom with enough of angle to pass the "marble test", to divert water away from where it's been settling and causing the damage.

Denray Posted April 21, 2013 Author Report Share Posted April 21, 2013 Thanks guys! [:-thumbu] Just think of all the horrible disasters waiting to happen at these horizontal trims. Click to Enlarge 65.63 KB Quote Link to comment Share on other sites More sharing options...
Marc Posted April 21, 2013 Report Share Posted April 21, 2013 Did you see anything indoors, along the exterior walls? Marc Quote Link to comment Share on other sites More sharing options...
hausdok Posted April 21, 2013 Report Share Posted April 21, 2013 There should have been a Z-flashing and spacers behind that horizontal trim and the upper and lower panel should have been a quarter or an inch apart with the z-flashing bent to drain. That enables you to have a 1/8-inch gap between the top of the flashing and the bottom edge of the upper panel and the spacers allow the water to drain out.

Denray Posted April 21, 2013 Author Report Share Posted April 21, 2013 No damage viewed on the interior. That exterior trim over the Z had no sealants where viewed.

The problem is you have no way to know whether it's right or if it is even there because you can't see it. OT - OF!!! M. Quote Link to comment Share on other sites More sharing options...
gtblum Posted April 21, 2013 Report Share Posted April 21, 2013 Looks like the windows aren't flashed, either? Quote Link to comment Share on other sites More sharing options...
Denray Posted April 21, 2013 Author Report Share Posted April 21, 2013 If the Z is correct the trim still traps water there. Quote Link to comment Share on other sites More sharing options...
hausdok Posted April 22, 2013 Report Share Posted April 22, 2013 If the Z is correct the trim still traps water there. Not if spacers are installed behind the trim. Quote Link to comment Share on other sites More sharing options...
Scottpat Posted April 22, 2013 Report Share Posted April 22, 2013 Typical hardboard siding failure.... The only cure is to replace it... Patching or cutting out the damage or covering it will only prolong the proper fix. Quote Link to comment Share on other sites More sharing options...
