I really like Fixer Upper. But, I do not believe in everything the Gaines do in remodeling. His structural rough framing is quite good, as far as I can see. But, some things he does would not work well in a different climate than Texas. Adding trim against a brick/rock wall can be done several ways. Pressure treated wood should be used to minimize wood rot. Plain construction lumber can fail in just a couple of years. The larger problem is the fact wood moves more than brick/rock, to it is pretty difficult to trim long term without problems. Added to that is the fact many bricks used in housing are hygroscopic, meaning they absorb moisture. The best way depends on the climate in which the house is in. Cool, wet climates( Western Washington/Oregon/SoCal) means trim should be plastic(Azek), since there is really no good way to mount wood and seal it against the damp. In hot climates(South and West US), wood will expand and contract enough to also be a problem. However, plastic expands more than wood. In the rest of the US, cold/snow in winter and hot/wet in summer pose the same problems. Installing can be done several ways(all allowing for the problems to a greater or lesser degree). Drill holes in the brick/mortar lines and use anchors/screws. Or glue in wood/plastic dowels and use nails/screws(the wood dowels will fail at some point in moist climates). Use concrete screws(Tapcons) or powder actuated fasteners(worst choice!!!). Or construction masonry adhesive. Lots of ways to do that, but none are really long term jobs.

It is so helpful to have pics in your idea books so we have a clue as to what you like, If you want really contemporay then no trim but IMO a simple trim ont he windows painted the same as the walls will be a nice clean look and a bit less expensive than no trim. Keep all the baseboards the same style of trim and door casings too I love MCM and Art Deco this is our LR to give you some idea . Very minimal trim and painted the same as walls.

What besides cedar trim did you think was an option? What's going on with the flooring and why is it so foreign in color from the balance of the room?
