Wood Windows Inc is not an authorized Sierra Pacific dealer. We service, repair, and replace Sierra Pacific windows and doors throughout the Treasure Valley. Sierra Pacific's clad-wood doors range from a simple French door to pocketing glass walls more than 20 feet wide, and this page is the owner's reference for all of them.

The Door Lineup, Configuration by Configuration

Sierra Pacific builds its doors on the same materials as its windows: 2-1/4-inch solid wood panels in eight species with CoreGuard Plus preservative, clad in extruded aluminum that runs 0.075 inch on panels and 0.062 inch on frames, powder-coated to AAMA 2605 in 50 colors. Glass is Cardinal Low-E on a no-metal TrueWarm foam spacer, dual or triple pane. What changes is how the panels move.

Bi-fold windows and multi-slide pass-through windows share the door construction at smaller sizes, and the FeelSafe impact versions exist for coastal codes that do not apply in Idaho.

Thresholds, Sills, and Idaho Weather

Sills are where big doors succeed or fail in a cold climate, and Sierra Pacific's three door families take three different approaches. The sliding patio door uses a conventional raised sill with an interlocking bulb weatherstrip. Multi-Slide Plus uses a 1-inch sill with interior stops at 1-1/8, 1-3/4, or 2-1/8 inches, or optional flush T-tracks at 11/16, 1-1/8, and 1-5/8 inches that carry no water infiltration rating; the company's own catalog notes that low-profile tracks need a stepped sill or similar installation detail to manage water. Lift & Slide uses a thermally broken, dark-bronze-anodized drain-track sill that weeps intruding water out through exterior gates, and because each panel drops onto its seal when the handle is turned, it holds the tightest air seal of the group when a January wind is pushing on 200 square feet of glass.

For a Treasure Valley home, that hierarchy matters. A pocketing multi-slide on a covered, east-facing patio in Meridian performs fine. The same door facing west on an exposed foothills lot is asking for sill leaks and cold-air infiltration; there we would have specified a lift-and-slide originally, and it is where we look first when an owner calls about drafts.

What Fails, and When

Rollers are the wear item. On a 300-pound panel, the bearings and wheels eventually flatten or seize, the panel sags, and the interlock no longer meets its mate, which shows up as a draft, a hard-to-latch lock, or a strip of daylight at the sill. Multi-point lock gearboxes on swinging doors wear at the 15-to-20-year mark. Tempered insulated glass units fog like any other IGU, typically on the sunniest exposure first. Bottom rails on outswing and bi-fold panels are the one wood-rot risk, and only where a sill pan or flashing detail let water sit; CoreGuard treatment buys time but does not make wood waterproof. Powder coat holds up well; dark colors chalk sooner on south walls.

Roller replacement and re-leveling, lock component replacement, weatherstrip, and glass are all services we perform on Sierra Pacific doors with our own crews. Because we are not a dealer, new Sierra Pacific parts come through the manufacturer's channel, and we help owners source them or fit compatible components.

Like-for-Like Replacement From Brands We Carry

When a door is done, the mapping is straightforward. Marvin's Scenic Doors cover multi-slide, lift-and-slide, and bi-fold in clad wood or fiberglass at comparable panel sizes. Andersen's Big Doors offer MultiGlide, folding, and Liftslide formats, and its patio doors replace a Sierra Pacific swinging or sliding unit almost dimension for dimension. For a contemporary aluminum look at lower cost, Milgard's AX550 and AX650 Moving Glass Walls are a legitimate substitute for a pocketing multi-slide. We confirm header and pocket dimensions on site before quoting, since pocket doors leave nothing to hide behind.

Warranty and Service, Locally

Sierra Pacific's residential wood/clad warranty covers dual insulated glass 20 years, triple glass 10, parts 10, labor 2, wood deterioration 20, and AAMA 2605 finish 30 years, transferable to later owners, with claims through Red Bluff at 800-824-7744. Everything beyond that, and everything an owner would rather have a local crew handle, is done from Garden City by Wood Windows employees, never subcontractors, 46 years running.

Frequently Asked Questions

What is the difference between Sierra Pacific's Multi-Slide Plus and Lift & Slide doors?

Multi-Slide Plus panels ride on two 2-1/8-inch stainless steel bearing rollers each and glide on a low-profile track, up to 60 inches wide and 119-1/2 inches tall per panel, in stacking or pocketing layouts. Lift & Slide panels are larger, to 72 by 120 inches, and the handle physically lifts each panel off its seal to roll, then drops it to lock down against a drain-track sill. The lift mechanism costs more and seals better, which is why we steer Idaho owners with exposure toward it.

Why does my Sierra Pacific sliding or multi-slide door leak air or water at the sill?

Two common causes. Multi-slide T-track sills at 11/16, 1-1/8, and 1-5/8 inches are low-profile by design and carry no water infiltration rating, so they depend on the installer's sill pan, flashing, and drainage detail. And the rollers on any big door wear, letting the panel sag so the interlock and sweep no longer meet the sill evenly. Roller replacement and re-leveling fixes the second problem; the first is a flashing repair, which we assess before recommending anything.

How much does it cost to replace a Sierra Pacific multi-slide or bi-fold door in the Treasure Valley?

A conventional two-panel clad-wood sliding patio door replaced with a comparable Andersen or Marvin unit typically installs in the mid four figures. Multi-slide, lift-and-slide, and bi-fold systems are custom-engineered and commonly run from the low five figures upward depending on panel count, height, pocketing, and glass. Those are broad typical ranges; every big door is measured, quoted, and structurally checked individually.

Can Wood Windows replace just the rollers, handles, or glass on a Sierra Pacific door?

Yes. We service Sierra Pacific doors even though we do not sell them. Rollers, multi-point lock components, weatherstrip, and fogged tempered insulated glass units are all serviceable, and on a big door a roller-and-adjustment service often restores operation for a small fraction of replacement cost. If the panel wood has taken on water at the bottom rail, we tell you honestly whether repair is throwing good money after bad.
