My opinion Therma Tru would be the lowest I would go on the food chain. I would seriously consider Provia at the very least for your front door.

We ordered our fiberglass door through ThermaTru. I can't speak to the quality of it yet as we have about 2 weeks to go before it arrives. I live in Texas and we've had a solid wood door for the past 11 years. It's under a covered porch and it's held up fairly well. It does swell during the summer humid months and it sticks. We opted for a fiberglass door this time around because I wanted a painted door, not stained. I've had stained the past 11 years and wanted something different so I figured why pay an upgrade for beautiful stain grade wood if I was just going to paint it.? Hopefully we like it!

OP hasn't shown the front door. The pedestrian door to the garage should be painted the siding color to blend into the siding. Having it a different, prominent color will cause confusion to guests and not enhance the house at all. The design of the garage doors does conflict with the design of the house portion we can see.

Millworkman - Not sure - we are looking to replace a metal entry door which was installed prior to us purchasing the 1912 Craftsman style home and investigating between wood or fiberglass. West facing but enough porch overhang to more than quailfy for standard wood door warranties. Would be a slab only as we want to preserve the existing leaded glass transom as well as the single sidelight. Doors4home.com has a wide selection, but no idea on quality. Buying local would be great, but the few custom shops we've visited won't sell just a slab.
