Those white painted rocks in the pics above make the house look like its made of marshmallow fluff! Not a good look. OP, Im willing to bet that those rocks are on the front only, am I right? Usually I argue in favor of saving original house parts but i have to say, the 50s thing for attaching fake rocks or brick veneer to the front only (like we cant see the sides??) is really annoying. Take it off! (Be sure to post after pics). Glad the tree is staying. Its not that close, and looks to be in good shape - a good tree adds value to a house. When the time comes redoing your front beds and adding a snazzy new door will add much more appeal.

Snap a photo on a sunny day then use the Sherwin Williams ColorSnap app to play with the colors. I would select a tone slightly darker than your mortar for the garage door and a color slightly darker than your darkest brick for the front door. I would then on the garage door install magnetic faux hinges and windows; this will add detail to the door, like the below house. I know they can be found on Amazon, not sure where else. Before: After:

Remove the shutters. I am not a fan of painting brick, especially brick like yours which is attractive. I would focus on the landscaping. Get rid of the pompom bushes. Extend the plantings from the side of the garage to line part of the drive, but add more variety. Plant an ornamental tree out in the yard to frame the entry. Plant a hardwood on the right side of the property. Some plants I would look into are oak leaf and pee gee hydrangea, mountain laurel, red twig dogwood. I like ornamental trees like Eastern Redbud, crabapple, snowbell, Crepe Myrtle.

Good info Juliet. I think I'm switching sides and getting aboard the stain train LOL. I just looked and there is in fact a wide range of masonry stain colors/ opacities - even some that look a lot like the light grays and blue grays in OP's pics above. The difference is it reads more like real brick vs. the thick paint coating on top which obscures the texture. BTW Ive always considered these forums to be a community-wide discussion, and by participating (commenting, reading responses from others, looking stuff up to be sure I know what I want to say) I often learn stuff too as much as the OP does, if not more so. Posters should not expect a one-on-one consultation - you will get whole gamut of opinion! But thats the value of this forum - some new direction might come up that you wouldnt get by talking to only one person. As maddening as Houzz often is, it really is a good resource!
