comment Is this vertical gap in the concrete block foundation something to worry about?
before i could comment, i'd want to see the crack from the inside. Cracks from settling are common, so age, displacement of the crack, and other factors effect the diagnosis.

comment How can I correct a plywood cabinet door that bowed after painting?
highly unlikely that a top coat of latex paint over a sealed plywood slab would cause this bow. I find it hard to believe that latex paint drying is strong enough to bow 3/4 inch plywood. I suspect the general humidity of the room or some other influence exists.

comment Enamel Canned Spray Paint on interior trim?
He can also spray some of the paint into a small paper cup and use an artist brush to touch up.

comment Enamel Canned Spray Paint on interior trim?
Kilz is an oil based primer. most lacquers should work OK on it. Still test a small piece to be sure.

comment How to flatten the sagging OSB subfloor?
you do no thave to seal the subfloor unless is it spoiled with pet urine of something smelly. No brand names on the compound, they all work fine for what you need to do. Just make sure it is embossing filler, not leveler. Leveler is hard as stone and very difficult to cut off ridges and sand. Makes a mess, dust. If you are careful, just a knife off of ridges and you are ready to lay floor.

comment What would cause the mortar to crack across a number of bricks?
This is a case of classic settling. Diagonal cracks from windows or lentils are so common on older structures. See them all the time. Jack is right on, if there is no displacement, or bricks coming loose, a simple repointing is probably your only reasonable fix. If internal trim, doors, windows etc are not effected, I would not get too excited.

comment How to increase height of existing concrete slab?
Adding 1 inch over existing can be successful with the advise you received from Sakrete. The key step you didn't mention is the etching of any exposed old concrete. A good bond is dependent on a properly prepped base. I would always recommend etching the old base with muratic acid, neutralize and be sure to flush completely. Then do the bonding steps and re-pour. Ever good bonding agents will not adhere well to dirty or efflorent concrete.

comment rotting a roof without proper venting
Can you explain what you mean by "no air layer"? Does this building have a solid roof over exposed rafters?

comment How to get a straight line when painting wall with fillet to ceiling
It is actually quite easy to get enough tension on a chalk line to get a very strait line, even over a span of 15 to 20 feet.

how do the European U values translate to R values here? Excellent illustration and index list.

comment Changing straight staircase to a turned stair with half landing, is this the Only solution to stairs cutting loft in half?
I think I understand what you want to do, but without seeing an existing and proposed floor plan it is very hard to visualize. Turned stairs with a landing are very common to change top landing locations of stairs and normally can be done with proper planning. I am not a fan of circular stairs, but they can be an option as well. if you can add some scale/visual details, we might be able to help you. A good carpenter should be able to advise you.

Good work wallyk. I don't like sistered beams. The overlap can be iffy. Lots of hardware. I'd do steel myself.

comment Should I install bracing behind drywall for upper cabinets?
In the USA, 15 inch and 18 inch cabinets are very common in the whole design. At best, you might find one stud, the question is on what try? LOL. If the wall is open, block it with 2X6. Been a contractor for many years and I'd never not install them if possible.

comment Can I remove this truss cross-bracing?
Sorry, i just saw your additional pics. If that is a structural brace, it is pretty flimsy. It doesn't seem to span an area that I would expect. Can you show me a pic of the roof from outside that is supported by these trusses? there must be some architectural detail there.

comment Can I remove this truss cross-bracing?
to be perfectly honest, without seeing the entire system and how they relate to each other, I don't want to mislead you. In over 20 years of building and inspecting, I haven't seen this type of cross bracing. Maybe if you can get a few more pics showing the relationship of the members, I can evaluate it better.
