Why replace

The biggest piece of glass in the house should seal tight.

  • Low-E Glass
  • Smooth & Secure
  • Quality Workmanship

A patio door is a wall of glass that slides or swings — which makes it one of the best features in a house and, when it's old, one of the worst air leaks. Worn rollers, failed seals and single-pane glass turn an old patio door into a draft you feel across the whole family room every winter. A new one fixes the comfort and the curb-to-yard connection at the same time.

We install sliding patio doors with smooth-gliding, low-maintenance hardware and French patio doors that swing for a more classic look — both with Low-E insulated glass that cuts heat transfer and UV. Vinyl and aluminum frames hold up to weather without warping, and modern multipoint locking makes a big glass door genuinely secure.

Patio doors are large and heavy, so the install is everything: the opening has to be square, the door set plumb, and the sill flashed so water drains out, not in. Our in-house crews size, set and seal the door correctly — no sticking, no drafts, no leaks — with careful, quality workmanship throughout.

Everything that goes into a tight, smooth patio door.

One in-house crew sizes, sets, flashes and seals the whole door — no subcontractors.

Patio Doors FAQ

Patio & sliding door questions, answered.

Feeling a draft from the patio door? Call us at (802) 321-3332 — happy to talk it through.

Sliding doors save space since nothing swings into the room and they're easy to operate — great for tight spots. French doors swing open for a wider, more traditional look and a bigger clear opening. We'll match it to your room and how you use the space.

Yes — old patio doors leak around worn seals and rollers and through single-pane glass. A new door with Low-E insulated glass, fresh weatherstripping and a properly flashed install seals the opening and stops the draft.

Modern patio doors use multipoint locking and tempered or laminated glass options that make them far more secure than older single-latch doors. We align the hardware properly so it locks solid.
