Believe It Or Not, It’s Just “Hanging In There”. Yes believe it or not this is rot. Ordinary wood rot is the process of decay due to the breakdown of the wood fiber components as they are exposed to mold, micro-organisms, insects and water. This is a complete ecology with the mold eating the wood and other things feeding on the mold and weakened wood and others feeding on them, etcetera, etcetera. It can occur right before your eyes, as in this case, as well as in hidden locations. Primarily all that is required is the relatively frequent recurrence or constant presence of water. Other than that it’s the right temperature range and the ubiquitous presence of mold spores and the rest of the micro-biology team. (They’re always waiting in the wings.) Here this is outdoors on a secluded corner of the veranda, and the caulk that was used to ‘seal’ where the wood and concrete touched is still there. Caulk only works between some materials, in drained conditions and is the back-up to proper flashing or other separation controls. Caulking instead of the classic separation and flashing details will only work for a short time. Here’s the shocker (for some);Believe it or not – Just like copper is a conductor for electricity, concrete (and cement and masonry) conducts water. It does not have to be cracked or broken to transmit water to wood in contact with it. Just being in touch, in contact is sufficient. That’s why framing sills (mud sills) and basement wall shoe plates have to be gasketed between the wood and the concrete. Old school material was tar paper. Now there are rolls of foam plastic/vinyl gasketing available in widths to match the dimensions of the wood. So in this case the caulking sealed out nothing. It actually prevented drying of the wood here which would have preserved it longer. The concrete conducted water to the face end of this 4×4 column and the end grain would draw in the water by capliarry action, similar to a straw but driven by chemical affinity rather than suction forces. This is how water moves in the living tree. So evert time this concrete surface got wet from weather or garden watering it delivered water to the wood. The paint and caulking kept the water in place so the wood rotted. Believe it or not, this was pressure treated wood. The rest of the column is dry and has no rot. The guaranty or warranty instruction for this product promises that it will last for 20 years outdoors provided it is not in contact with water or water retaining materials. It can even be in ground contact as long as it rests in a drained gravel bed. Fortunately for this homeowner this column is not structural. It’s just “hanging in there”.

The Double Header: Concentrates the rain to get BOTH shoulders as you walk up the stairs! (This is #2 in a series on a single flipped house.)
Yes that’s right.
The original owner of this flipped property installed the gutter system to keep you dry, from the roof runoff at least, when you walk up the steps to the side door. (The everyday entry for the family).
The flipper replaced the old wood steps and landing, removing the downspouts in the process. And then he left things ‘up in the air’, literally! It probably wasn’t raining on the day that he finished or hoped it wouldn’t be when the house was being viewed. It wasn’t raining when I inspected but I did not miss it.
Now look at this configuration. This is the bottom edge of a flat low slpoe roof surface with a wider overhang where the side door is The trough or guttering is continuous. It’s all a the same height. OK
So why are there two downspout drops here in the same area? Why is it like that?
The answer it the gutter troughs are basically level. There is no grading, no slope to cause the water to drain to a lower point where the downspout is positioned. This incorrect. The minimum is a 1″ drop in 12 feet. I recommend more as such a minimal flow is easily disrupted or blocked.
So the gutters ‘pond’ (fill up with water) till it reaches the downspout drain, but some water always stays there. Its like having a bath tub that tilts away from the drain. There will always be a puddle of water in it.
That ‘ponding’ causes side effects. Leaves collect there. They compost to a mud. This raises the water levels and causes furthur blockages. Water can be held against wood facia boards causing them to rot. Metal clad facias still have wood behind and the metal cladding has overlapping joints, but they are not sealed. Water will get in.
What does this show us?
It routinely overflows and drips, so that means the downspouts are often blocked. We also see facia details that tell us it is made of wood, covered in the red toned metal and the joints are overlapped but not sealed.
As an experienced professional inspector I will understand that the original guttering was not correctly installed.
The gutters remain unsloped, prone to ponding and overflowing and will need more than normal maintenance to keep clean and operational.
There are conditions conducive to the rot and decay of the roof facias. The metal flashing will keep any such condition hidden for a long time, but I will be advising my client of this risk.
And of couse the downspout system remains incomplete, ‘up in the air’ where the flipper left it.
This is #2 of a series on the same flipped house.

Most of you probably slept right through it (the quake), Yes – we usually do.
That’s right, we usually do, or other wise not notice because we’re driving or otherwise in motion. Yeah, I’m talking about last night’s earthquake.
I’m usually one of those who ‘miss’ it but last night was the exception. I experienced a 10 second pulse of shaking that left no doubt as to what it was.
Some people heard a bang and some experienced just shaking. If you or your property is on rocky ground or bedrock you’d have heard the bang more. If your house sits on clay you’d have been shaken longer and heard less noise. Those on higher floors do sometimes feel more motion, depending on the type of structure.
As a Montreal home and property inspector I have to tell you that whether or not you noticed it, your house surely did. You may have some wall or basement cracks appear, existing cracks open and close, or there may be no noticeable effects at all.
I often get asked if basement cracks are structural and what the cause might be. Same thing for wall cracks in 1950s built homes.
Last night we experienced a rare occurrence (thankfully) that does cause this type of cracking.
If you have a crack in concrete or masonry that has opened more than a pencil thickness, or has one side moved (in-out, up-down) compared to the other side then you should have it evaluated by a professional like me.
1950s built homes with plaster-gypsum lath walls are rigid and inflexible. They crack easily. Hairline cracking is common.
But if your walls are joint taped gyproc (i.e. drywall) and you have a new crack after last nights quake then that is more significant because this system already allows some movement.
Call or email me if you have any doubt or concerns.

N.B. The quake occurred in the fault line (system) that is responsible for the straight north south axis of the Richelieu River. Most major rivers have such fault lines associated with them.
