Sliding Glass Door Repair
For the door that took all winter to get this bad
If the door needs two hands and a shoulder, the rollers underneath it have collapsed. We replace them, deal with the track they damaged on the way out, and reset the panel square — on site, usually in a single visit.
Nothing about the door itself has broken
A sliding glass panel is heavy, and its whole weight rides on four small wheels. When those wheels flatten or seize, the panel stops rolling and starts dragging along the track. It feels heavy, it sounds wrong, and each month it cuts a deeper groove into the rail underneath.
Rollers are consumable. They are meant to be replaced. What goes wrong is that homeowners get quoted a complete patio door replacement for a part worth a tiny fraction of it.
Colorado adds one twist: a door that has been dragging all winter has usually had ice and grit in the track the whole time, which means the rail almost always needs attention alongside the rollers.
A sliding door should move with one finger. If yours does not, that is a repair.
Every part of a sliding door
Our vans carry the common roller, track, hardware and screen components, so most jobs finish on the spot.
Roller replacement
Flattened, seized and corroded rollers swapped for sealed steel-bearing units, with tandem rollers where the panel weight needs them.
Track repair and capping
A gouged rail destroys new rollers within months. We repair the track or cap it in stainless so the new parts run true.
Glass replacement
Cracked, shattered and fogged panels replaced in tempered safety glass, fitted into your existing frame.
Locks and latches
Latches that miss the strike, worn handles, foot bolts and auxiliary locks on the most common point of forced entry in a home.
Weatherstrip and draughts
Seals that have gone hard and brittle, letting cold air straight into the room along the closing edge.
Sliding screen doors
Rescreening, new frames cut to your opening, roller and latch replacement, pet-resistant mesh.
What a Colorado winter does to a slider
Three things account for most of the sliding door work we do here.
Freeze and thaw, hundreds of times a year
Colorado runs through more freeze-thaw cycles than almost anywhere in the country. Water gets into the track, freezes overnight, expands, and thaws by afternoon. Repeat that all winter and rollers, seals and rails all take damage.
Road grit gets tracked inside
Sand and de-icing material from driveways and sidewalks comes in on boots and settles straight into the door track. Mixed with lubricant it becomes a grinding paste, and it is the single biggest cause of early roller wear here.
Extreme daily temperature swings
A forty-degree swing between morning and afternoon is routine on the Front Range. Aluminium frames expand and contract through that range every day, loosening fasteners and drifting panels out of alignment over the years.
Why homeowners across the state call us
This is the repair we do more than any other, and it shows in how quickly it goes.
We repair, we do not upsell
If the frame is square and the glass is sound, you need parts and labour, not a new door.
Finished in one visit
Rollers, track caps, hardware and seals ride on the van, so there is rarely a second trip.
Parts built for the conditions
Sealed steel-bearing rollers that keep grit and moisture out of the mechanism.
A firm price before we start
You get the number up front and it does not move once work begins.
Three steps, no runaround

Sliding door questions
How do I know whether it is the rollers or the track?
If the door drags but the rail still looks clean and smooth, it is the rollers. If you can see or feel grooves and burrs in the metal, both need attention. We check both at the estimate.
My door is frozen shut in winter. Is that damage?
Not necessarily, but it is a warning. Water sitting in the track means the drainage is blocked, and repeated freezing in a track will eventually distort the rail and wreck the rollers.
Can the track be repaired, or do I need a new door?
Repaired, in nearly every case. A stainless cap fits over the damaged original and gives the rollers a hard, true surface. Replacing the frame is rarely necessary.
My door came off the track. Should I lift it back on?
Please do not. The panel is heavy and awkward, and forcing it can chip the rail or crack the glass. It will not stay on either, because the rollers have collapsed.
How do I keep it working afterwards?
Vacuum the track a few times a year, especially at the end of winter, and use a dry silicone lubricant rather than an oil-based spray. Oil holds grit, and grit is what wears rollers out.
Other repairs we handle
Doors and windows are all we do, so whatever has failed, it is probably on this list.
