Question DetailsAsked on 8/13/2014

We have leaks coming from the ceiling on floors 1 & 2 of our 3 story home. Who could we call to get help?

Both leaks are by windows on the same exterior wall and are by a chimney that runs up this wall. This has happened a few times. We have caulked windows. Water used to come in through window until we had it caulked and palced a copper awning over it.

Sounds to me, since you apparently think windows or siding or chimney interface or maybe the chimney itself might be the cause, this is a prime candidate for thermal infrared imaging.

Some auto parts stores rent thermal IR scanners, and Home Depot just started to roll out a rental for them (might or might not have hit your area yet) - otherwise many energy auditors have them, as do a few window and siding contractors but not many. It should be done shortly after your leak has presented after a rain, so the wall is wet to show on the imagery.Typically about $100-150 range for a single leak scan, or you could go for the whole house scan at the same time is paying for a contractor, for more like $200 plus or minus about $75 range for a whole house scan inside and out, with digital video record on a digital medium - DVD on some, thumb drive on others, camera type SD card with others, so be sure to negotiate up front for format the data is to be presented in, and be sure it does not require proprietary software to view - should be in wmv or mpg or similar common video format so you can view it at your leisure on your computer.

Another thing you could do is simulate rain with a hose, slowly moving it over the wall from bottom to top - the problem with that is you do not know how long it takes for the leak to make it to visible inside what with leak infiltration and saturating insulation and such, so you can either pump a LOT of water into the wall, or move the hose too fast so when the water pops through you think it is coming from where the hose is now when it actually came through the outside wall several minutes ago. Therefore, while this method works nicely for roof leaks, I do not recommend it for walls.
