I’d highly recommend Kevin McBrearty, who owns a company called The Door Guys.
His main line of work is installation of doors and windows (both of which I’d also highly recommend him for), but our general contractor also insisted on using him for all of our molding, and I can see why because he did a fantastic job.
Our architect spec’d a 3-piece molding around the windows (Craftsman style) along w/a certain sill configuration and wanted it to be very authentic so it had to be very precise in its measurements. Kevin was a real trooper about it…first, he mocked up a sample of the molding and installed it around one of our windows and asked me to look at it. When I thought the proportions didn’t look right, he stopped the job and waited for our architect to come out the next day and discuss it. He changed it ever so slightly without a hint of annoyance (unlike most of the other contractors, who couldn’t stand taking orders from an architect). It was clear that his entire goal was to please us all.
He was definitely one of the most professional, knowledgeable, “can-do” guys on our job and was a true pleasure to work with. His work was top-notch and he left the area pristine at the end of every day. He was also quick and reasonably priced…even though our renovation/addition was done a couple years ago, to this day, he stands out in my mind as one of the best subs on the job.
By the way, I completely agree that you only need and should use MDF for your moldings and in most cases, a custom molding is definitely not necessary! It was one of the few areas where we splurged on our job, and although it was a 3-piece molding, none of the pieces had to be custom milled or it would have gotten way out of control.
