French door installation, swings true.
French doors bring in more light and open a patio up wider than a standard slider, and they only work well when both panels are set true. We install them across Denver Metro so they meet in the middle and seal tight every time.
A door that seals, swings true and locks the first time. We measure the opening, walk you through the styles that fit the house, and put the price in writing before anything is ordered.

Precise Windows LLC installs French doors for homes across the Denver Metro area, from Wheat Ridge to Lakewood to Denver itself. A French door installation means setting two swinging panels into one opening so they meet cleanly at the center and seal against the frame on all sides, rather than sliding on a track like a patio slider. It is a common upgrade for a patio opening or an interior room that wants more light and a wider walk-through than a single door allows.
Are you tired of your patio slider blocking half the opening?
A slider only ever opens half its width, since one panel is fixed, while French doors swing both panels open for the full width of the opening. If you are replacing an old slider or a single patio door and want the whole opening usable, French doors are the direct upgrade. The tradeoff is that both panels have to be set square and aligned with each other, since a French door depends on the two panels meeting evenly at the center to seal and latch, unlike a slider that only has to line up with one track.
Signs it is time to replace what you have
Light around the meeting edge
If your current double door shows daylight where the two panels meet, the weatherstripping or the alignment between them has worn out.
Panels stick or drag
A settled frame or worn hinges will cause one or both panels to drag against the threshold or bind against each other.
Latch won't catch on the astragal
The active panel locks into the fixed panel's astragal, and once that alignment is off, the latch stops catching reliably.
Constant draft at the center seam
Worn weatherstripping along the meeting edge lets air through even when both panels are closed and locked.
What we look at before recommending replacement
Frame condition
We check whether the existing frame is still square, since a French door install depends on a true opening for both panels to seal correctly.
Hinge and hardware wear
Worn hinges let a panel sag over time, which throws off the seal at the center meeting point.
Glass and energy performance
Older single-pane glass in a double door loses more heat than a modern insulated unit, which is worth weighing against a straight hardware fix.
Weatherstripping at the astragal
The seal where the two panels meet wears faster than the perimeter weatherstripping and is often the first thing to fail.
What to expect during the visit
We measure the opening for a matched pair of panels and go over glass options, including insulated units, along with hardware for the active and fixed panel. On install day, we set the frame square in the opening, hang both panels, and adjust the hinges so the panels meet evenly at the center and swing without dragging. We fit the astragal hardware so the latch catches cleanly, then seal the frame around the full opening. Before finishing, we run both panels through several open-and-close cycles and check the seal at the meeting edge and the threshold.
Related services you may need
If the glass in an existing double door is fogged or the frame has taken hail damage, Window & Glass Repair or Storm & Hail Damage documentation can be handled alongside the installation. Exterior Painting is also common right after a new French door goes in to match the surrounding trim.
The cost of waiting
A double door that is out of alignment tends to get worse on its own, since a sagging panel puts more strain on the hinge holding it and on the seal at the meeting edge. A gap that starts as a draft can let enough moisture through over time to affect the frame and the wall around it. Addressing it while it is still a hardware and seal issue is simpler than waiting until the frame itself needs work.
Can I replace a patio slider with French doors?
Yes, as long as the existing opening can accommodate a framed double-door unit, which most standard patio slider openings can. We measure the opening on site to confirm fit before ordering the doors.
What affects the cost of a French door installation?
Panel size, frame material, and glass choice are the biggest factors, along with whether the existing opening needs framing adjustments to fit a double-door unit.
How long does a French door installation take?
Most installations are completed in a single visit once the doors are on site, since the work is contained to the one opening and its frame.
If you are ready to swap a slider or single door for French doors, call Precise Windows LLC to get the opening measured. We install across the Denver Metro area, Monday through Friday.
