What keeps your home dry isn't the siding you see — it's the weatherproofing you don't. House wrap, flashing, and moisture barriers form a drainage plane behind the cladding that sheds water outward and lets wall cavities dry. Done right, this hidden system is the difference between siding that lasts decades and siding that quietly hides rot. Pay special attention to penetrations — hose bibs, vents, electrical boxes, and fixtures — since every hole through the wall is a potential leak path needing proper flashing or sealing.
Weatherproofing matters most during installation or replacement, when walls are exposed — that's the moment to add or upgrade house wrap, seal penetrations, and flash windows and doors correctly. Retrofitting behind existing siding is harder and costlier. Ask for photos of the weatherproofing layers before siding goes on; once cladding covers the walls you'll never see that work again, and documentation proves it was done right. Planning a siding project? Call and we'll connect you with an experienced siding contractor in Washington, DC who takes the hidden layers seriously.

Exterior Caulking — FAQs
House wrap is a breathable membrane installed behind siding that blocks liquid water while letting vapor escape. It's standard in quality installations and a key part of a healthy wall.
Around windows and doors, along rooflines, where decks attach, and anywhere siding meets trim or masonry. These transitions are where most leaks start.
Partially — some flashing and sealant work is possible from the outside. Full barrier upgrades usually happen during re-siding, when the walls are exposed.
A rain screen is a vented gap between the siding and the wall that improves drainage and drying. It's commonly used with fiber cement and wood siding for extra moisture protection.
