'cabinets'

If your woodworking skills are not up to fine millwork…just do this;
Nail wooden boxes to the wall.

The wrinkle now is to find wooden boxes like this not being sold as antiques.

Carpenrtry 312:

The diagonal wall brace seen here is a good example of a ‘let-in brace’. There are 6 of these stiffening the walls of this garage.

This was done in the days before the use of skill saws and availability of plywood. If plywood was used as sheathing on the exterior wall, the bracing would not be needed. 

These notches in the studs fit tight, prevent sideways or lateral wracking of the frame and fit leaving a flush surface so interior finishes can be applied.

This is all hand work. Powered saws always leave overcut kerfs in the wood and it’s a rare carpenter who fits joints as tight as this using such a saw.

 

So this is a bit of history, but because the house and garage where built at the same time it shows me how the framing of the house was executed even though I can’t see into the house walls.

(AP) The apartment was dirty with mold. Insurance wouldn’t settle. An OMG File.

 The apartment was dirty with mold. Insurance wouldn’t settle.    It was A.P.          An OMG File.

girl wearing mask

I was calling to investigate a ‘mold’ problem that turned out to be dirt, soot in fact.

I asked my client why she thought there was mold. She brought out the air quality test report.

As I was reading it, her daughter came in from the other room. She was home sick from school and wearing a face mask.

She had respiratory problems. My hair stood on end.

“When is her medical appointment?” I asked. “Tomorrow” was the answer.

“So when you go see the doctors bring this air quality report and show them theses two words that I’ve underlined here.” So they did.

I called to follow up a week later and asked how the appointment went. Both the mother and daughter, as well as everyone else who lives in that building (8 people), are being sent to see specialists.

Oh yeah the two words; aspegillius penicillii ………(AP)

This is the plural form of aspergillus penicillium. This is a seriously severe group of molds that are toxic to humans and animals.

So if you have any reports or documents that read as if they were latin, have them explained to you.  A lab technicians report is only data.  It won’t tell you if a condition is serious or what to do about it.

Report interpretation and remedial consulting is a part of our service in the Montreal area.

What Is It? And Why Did A Chippie Make It?

Gable wall

What Is It? And Why Did A Chippie Make It?

Well first you might ask is ‘What’s a chippie?’ Well that’s simply an old term for a carpenter or wood fitter, because they were very effective in removing large amounts of wood with adzes, axes and chisels.

This is of course in the days before power tools and literally ‘the chips were flyin’. A good tradesman kept his tools sharp so when notches or long rip cuts were required they reached for the blades first.  In skilled hands this was faster than the alternative and very accurate.

That’s the chippie, but what is this and why is it different? This looks similar to but not the same as what is built today. The shape tells us its the interior of an attic gable end wall, but they aren’t built like this anymore.

This photo shows a 50s build, near the end of an era for this type of construction which was used for hundreds of years. You can’t see it in this photo but the wall ‘boards’ are 3″ thick. They are the wall. There are no studs!

Yes 3″ thick!

This is not the platform, western, or balloon framing known to the current generation of carpenters and builders. There are no studs here!

This is more closely related to log cabin technology than anything else. It isn’t fitted with corner notching the way logs were (modern nails are used) and the ‘logs’ have become squared timber planks. (The camera flash makes them look dressed but they are actually rough sawn.)

The french called this method ‘pièce sur pièce’ (piece over piece) and it a compression technology that structurally transmits weight the same way stone and masonry structures do.

Some pieces were “keyed in” with birds mouth notch joints like this photo;

piece over piece joint

Note the small nails relative to the timber size. This is toe nailing. Its function is just really to hold it in place. The fitting, notching and weight are what do the work in holding the wall together.

Doors and windows have to be preplanned to fit under the bays formed by theses notched beams. You can’t just cut holes in these walls and frame a door or window opening. There is no ‘point loading’. All pieces cary weight

Floor framing is not a built platform as it is done now. Rather individual joists are ‘let in’ notched into the exterior walls a seen below;

piece over piece joist

Typically the vertical pieces had grooves in their sides that the horizontal pieces were notched into (similar to a mortise and tenon joint). Positioning and spans were a product of the size of the materials avaliable.

Exterior walls were commonly faced with brick, while inside faces were furred out and plastered.

Both faces of the wood were protected with tar paper. The exterior was done to protect the wood from the drainage plane behind the masonry (typically a one inch air space.. The inside was similarly protected against the huge volume of water temporarily introduced to the building by the plastering process. It often took up to three months to dry out.

Interestingly, although there is no insulation product installed here, the whole wall assembly is rated at nearly R20. Not bad for ‘no insulation’!

This construction can be found in most city cores in brownstones and masonry clad structures. Like the first photo they are also found in 50s build suburban housing divisions. It was a good solid building method.

It does have some drawbacks. Compared to current construction it uses a massive amount of wood and quality was hugely dependent upon the builders experience and knowledge as well as the tradesman’s skills.

Structurally it is sound but it does not lend itself to easy renovation. Any changes require an engineers consultation and an experienced crew.

As an inspector I field calls with people asking if I have experience with certain areas of the city. What they are really asking is if I understand how those homes are built and will I be able to recognize thier particular problems and know it they have been correctly renovated in the past.

And thats a fair question. Thats the service needed for homes built this way.
