Black-Frame Windows & Sliders on a Siesta Key Waterfront New Build

This is a large two-story new home on a canal on Siesta Key. When these photos were taken the house was still at the bare-wall stage: concrete block on the ground floor and in the stair tower, framed sections on the upper level, roof fascia on, no stucco yet. Our part of the job was the openings. Black-framed windows went in on both floors, and the back of the house got a run of black sliding glass doors that look straight out at the water and the docks.

Start with the exterior shots. On the block walls every window sits inside a wide white band. That band is the waterproofing around the rough opening, brushed onto the block before the unit is set so the opening is sealed edge to edge. Below the balcony you can see two big multi-lite units with grids and three tall single-hung windows on the garage wing. Up top there is a tall glass unit that opens to the second-floor balcony, still behind a temporary wood rail, with a row of smaller windows next to it. The framed upper sections are sheathed in ZIP System panels, and each opening there is trimmed with flashing tape instead of a liquid coat. Two wall types, two flashing methods, one weather line.

The last photo is from inside, looking at the canal. The ceiling is still open floor truss with flex duct, and the framed walls are faced with R-Max Thermasheath foam board. The main opening holds a three-panel black sliding door with no mullion clutter, so the view is mostly glass. To the left is a second, two-panel slider with a fixed transom above it. The tall transom keeps the head height of both openings in line, which is what lets the wall read as one design instead of two doors.

Why does the window installer come before the stucco crew on a new build like this? Because the window is part of the wall's water barrier, not something hung in it afterward. We set the unit, fasten it into the block or framing per the product approval, seal the perimeter, and only then does the stucco wrap back to the frame. If stucco goes on first, the joint at the frame becomes a caulk line and nothing more. On Siesta Key that matters. The whole island sits in the wind-borne debris region, so openings need impact-rated glazing or approved shutters, and the units must meet the design pressure the engineer calculated for that wall and that height.

Large sliders on the water side get extra attention. The sill track sits on a level, sealed bed so it drains to the outside, not into the slab. The panels are sized to the design pressure for that elevation, which is often higher near corners and on the exposed canal side. And the track and rollers have to handle salt air, which is why we talk with the builder early about frame finish and hardware.

If you are building on the water, ask any installer a few things before the walls go up. Which Florida Product Approval or Miami-Dade NOA covers each unit, and do the design pressures on it meet or beat the engineer's numbers? How will the openings be flashed on block and on framed walls? Who seals the sill of the sliders, and what is the plan when stucco meets the frame? A good answer to each one should be specific.
