Pairing dark charcoal shake with crisp white trim leaves zero room to hide sloppy seams. Running Cedar Impressions across an entire exterior means every lock has to engage cleanly while keeping proper spacing for seasonal movement.

Backed up with new GAF shingles up top and fresh Harvey double-hungs all around, this coastal home is buttoned up tight.

From removing the old window to preparing the opening, every step matters. Flashing tape pressed tight under the nail fin helps keep water where it belongs, while finish caulk is just the final detail.

Doing the garage at the same time as the main house saves a lot of second-guessing down the road. Thirty-seven squares of Shakewood gave both buildings an even look, right down to the brown drip edge and fresh copper around the chimney.

Copper flashing against fresh Shakewood shingles is hard to beat. We wrapped up this full house and garage install with brown drip edge to tie the whole exterior together. The copper detail around the chimney really gives the roofline that clean, custom finish.

The right color combination can make all the difference.

Harvey double-hung windows in Almond, Monterey Sand exterior wrapping, and a new storm door come together for a soft, cohesive exterior that complements the home’s existing character.

Fresh siding and new windows completely change the look of Smokin' With Chris. The Sandstone Beige exterior pairs perfectly with those bold black gutters. Large Harvey picture windows complete the setup by letting in plenty of natural light. It is a massive upgrade for a local favorite.

Stop by to see the fresh look and grab some great food.
