Idaho door & window repair
Sliding glass door repair
Sliding Glass Door Repair
Four small wheels under two hundred pounds of glass.
When those wheels give out the panel stops rolling and starts dragging, which is why the door got heavy, why it grinds, and why the track underneath is now damaged too.
Do I need a new door?
Almost never. Rollers are a wear part.
How long does it take?
One to three hours, finished in a single visit.
Is the track ruined?
Often damaged, almost always repairable.

How a slider actually works
Understanding this is the difference between a two-hour repair and a quote for a replacement door.
Idaho's building boom fitted an enormous number of builder-grade patio doors with light-duty nylon rollers. They were adequate new. Ten to twenty years on they are the single most common repair we are called out to.
The panel
Tempered glass in a frame, commonly eighty to two hundred pounds. All of that weight sits on four small wheels.
The rollers
Wear parts, meant to be replaced like tyres. They flatten, seize or break up, and then the panel drags instead of rolling.
The track
A metal rail set into the sill. Once a roller collapses it grinds that rail, cutting a groove that will destroy the next set of wheels.
The interlock
Where the moving panel meets the fixed one. It has to seat along its full height or the door leaks air at the closing edge.
The weep channels
Drainage beneath the track, designed to send water back outside. Blocked weeps are why water ends up inside instead.
The latch
Catches a keeper on the jamb. When a panel drops even slightly, the latch stops lining up and the door will not lock.
Diagnosis
What the door is telling you
Sliders fail in a predictable sequence, and most people call us partway through it.
| What you are seeing | What it usually means | What we do about it |
|---|---|---|
| It takes two hands | Rollers have flattened or seized and the panel is dragging | Replace the rollers, clear the track and reset the panel height |
| A grinding or scraping noise | Metal on metal where a roller has collapsed | Replace rollers and address the rail they have been grinding |
| Visible grooves in the track | The rail is worn and will chew through new rollers | Cap the track in stainless so new wheels run on a true surface |
| The door will not lock any more | The panel has dropped, so the latch misses the keeper | Reset the panel height; the lock usually works again untouched |
| Cold air at the closing edge | Interlock gaskets have hardened and stopped sealing | Renew the interlock seals and weatherstrip |
| Water in the track after a thaw | Weep channels blocked with grit | Clear the drainage and reseal the sill |
Idaho conditions
What Idaho does to a slider
Grit, freeze-thaw and a great many doors built in a hurry.
01
Dust and grit in the track
Agricultural dust across the valleys, construction dust from a decade of building, and road sand in winter all end up in the door track, where they mix with lubricant and become a grinding paste.
02
Freeze-thaw on the rail
Water sits in a track, freezes overnight, expands and thaws by afternoon — repeatedly, all winter. It distorts rails, splits seals and destroys rollers that would have lasted elsewhere.
03
Light-duty hardware at scale
Rapid growth meant a vast number of patio doors fitted with the cheapest adequate roller available. Those doors are now reaching the age where all of them fail at once, across whole subdivisions.
04
Dry air on the seals
Low humidity and strong sun make interlock gaskets and weatherstrip go hard and chalky years before their rated life, which is when the draught at the closing edge starts.
The honest version
Repair the slider or replace it
We only repair, so take this as a diagnosis rather than a pitch.
Repair is the right call when
- The frame is square and the glass is sound
- Rollers, track, latch or seals have failed
- The panel drags but lifts out cleanly
- The track is worn but the sill is solid
- The door is a common builder-grade system with parts available
Replacement is genuinely warranted when
- The frame has corroded or racked out of square
- The sill is damaged beyond capping
- The panel itself is delaminated or the frame has failed
- It is a discontinued system with no parts and several failures at once
A capped track and a set of steel-bearing rollers costs a fraction of a replacement patio door and lasts longer than the original hardware did.
What the visit looks like
One visit, most of the time
Before we arrive
Send a photo
A shot of the door and one along the track tells us whether this is rollers, rail, or both.
On arrival
We lift the panel
Rollers, rail, interlock, drainage and latch all get checked, because these faults cascade into each other.
Before any work
A firm price
You get the number before the panel goes back in, and it does not move.
Same visit
The repair
New rollers, track dealt with, panel levelled, latch realigned and the track cleaned out.

Questions
Sliding door questions
Is it the rollers or the track?
If the door drags but the rail still looks clean, rollers. If you can see or feel grooves in the metal, both. We check both at the estimate.
Can a worn track really be repaired?
Yes. A stainless cap fits over the damaged rail and gives new rollers a hard, true surface. Replacing the frame is rarely warranted.
My door came off the track. Should I lift it back on?
Please do not. The panel is heavy, forcing it can chip the rail or crack the glass, and it will not stay on because the rollers have gone.
The house is fifteen years old. Are parts available?
Yes. The builder-grade systems fitted across Idaho in that period are extremely common and well supported.
How do I keep it working afterwards?
Vacuum the track a few times a year and use a dry silicone lubricant, never an oil-based spray. Oil holds the grit that wears rollers out.
Can you do the screen door at the same time?
Yes, and it is worth it. The screen runs on the same opening and is usually in similar condition.
