Best to install crown molding Walnut Creek CA

Install a basic crown molding in an apartment. Need thre rooms, bedroom, bathroom and entryway. Nothing fancy straight 45 degree cuts with one exception which is there are 6 rounded corners that will require a non 45 degree cut.

For normal off-the-shelf wood, high density, foam, plastic, MDF, etc molding, Carpentry - Woodworking would be the normal Search the List category to fond well-rated and reviewed companies for that type work. Probably all Handymen do it too, but how good the joints would be would depend on the individual's experience and attention to detail - sort of a tossup whether you would be happy with the result.

When you say rounded corners, bear in mind normal molding does not behave well in tight (less than about 1 foot or more radius) curves - normally specialty "deeper" molding corners are put in that situation - or a beveled piece of molding is put "across" the corner rather than trying to follow the corner. Some links to images/articles on that below FYI:

One common solution is to cut a 45 degree bevel piece to fit (which on "outside" corners means the actual straight pieces of trim coming up to the corner run along at the corner, past the end of the flat part of the wall, then after very wide masking taping top and bottom, put non-shrink drywall compound on the curve and press the bevel cut (many times a compound bevel cut if needed) into the drywall compound, filling the voids between the curve and the molding. Then immediately hand tool shape the squeezed out drywall compound to the correct configuration to match the trim and curve shape, removing all the excess compound in that provess. Then - and this is VERY important - cut through the tape with a razor blade or SHARP utility knife at the edge of the trimmed compound, and peel away the extra tape. Requires use of mesh or paper masking tape, and not extending very far under the compound, but gives a very clean finished edge to the shaped compound. Can take a week ro so to dry before paint ready.

For plaster molding, a Plastering (your Search the List category) company experienced in that, or a specialty historic building restoration company (especially if putting up custom fabricated plaster or injected resin molding) would be the type of company to search for.

Not technically legal becauser it is removing some load-bearing wood on the corner studs, but I have seen some people just use a rasp or cut and chisel off the corner of the drywall and corner stud to trim the corner where the molding is going to go to a 45 degree bevel (on outside corners of course) - though this results in the bevel piece being somewhat recessed into the top of the corner drywall. Also does not work easily if the corner has corner beading embeded in it.
