Sliding door or slide-and-stack?

Both let in plenty of light. The difference is how much of the opening you get and what the opening needs.

What makes a patio door seal

Big glass only works if the door is built and set right.

A patio door that leaks air or water is almost always a door that wasn't set level, flashed or sealed properly. That's where installation matters.

  1. Low-E insulating glass

    Reflects the sun's heat while letting daylight through, which matters most on west- and south-facing patios.

  2. Level, flashed sill

    The sill is set level and flashed so rain drains out, not into the floor or subfloor.

  3. Rollers, track and hinges

    Smooth rollers on sliders and sturdy hinges on bifolds keep panels square, so the weatherstripping meets them all the way around.

  4. Multi-point locking

    Locks that pull the panels tight into the seals, for security and a tighter seal.

Questions

Sliding & bifold door FAQ

What sliding door do you install?
The Genview M-1500 Series: a thermally broken aluminum sliding door built in Dallas, with triple-layer Low-E tempered glass, up to four panels and six finishes. Stock sizes run from 5 to 12 feet wide, and custom sizes are available. See the specifications.
How much does a new sliding glass door cost?
As a broad range, a replacement sliding glass door often runs about $2,000 to $6,000 or more installed, depending on the frame, glass and size. Larger multi-panel doors can cost more. See our sliding door cost guide.
Does a Glass Expanse door cost more than a sliding door?
Yes, usually. A slide-and-stack system has more panels and hardware for the same width, and the opening often needs to be widened. We price both in writing at your assessment so you can compare.
Can a Glass Expanse door go where my sliding door is now?
Sometimes. Glass Expanse systems start at 5 feet wide, but most homeowners choose one to open up a wider wall, which can mean a new header. We check the framing at your assessment and tell you what it would take.
What is the difference between bifold and slide-and-stack doors?
Bifold panels are hinged together and fold like an accordion. Glass Expanse slide-and-stack panels hang from a top track and slide individually, then stack to the side, so they can sit in several positions and leave only a very thin track at the floor.
Can you match my new windows?
Yes. We match patio doors to your new windows in color and finish. See our window lines.
How long does a patio door install take?
Most sliding door replacements take a day. Doors are made to order, so allow a few weeks from order to install. Slide-and-stack systems that need a wider opening take longer.
Can I pay over time?
Yes. See Financing.
