Sliding Glass Door Installation & Patio Door Installation
A sliding glass door installation is only as good as the opening it sits in. Our technicians measure the rough opening, check the sill for level, and inspect the header before a single panel comes off the truck — because a patio door installed into an out-of-square opening will bind within a season no matter how good the unit is.
We install two-panel, three-panel, and pocketing sliding patio doors in vinyl, aluminium, wood-clad, and fiberglass frames. Every installation includes a properly bedded sill pan, insulated and sealed jambs, and a full glide-and-lock test before we leave. If you’re opening up a wall or replacing a smaller window with a patio door, we handle the framing side of the job too.
Sliding Glass Door Repair & Patio Door Repair
Most patio door repair calls come down to four things: rollers, track, glass, or hardware. All four are fixable, and in most cases they’re fixable in a single visit — you rarely need a whole new door just because the old one has stopped sliding.
Our technicians carry replacement rollers, tracks, handles, latches, and weatherseal, so a diagnosis usually turns into a completed repair the same day rather than a second appointment a week later.
Sliding Door Roller Replacement
Worn rollers are the number one cause of a heavy, grinding patio door. The wheels flat-spot, the door drops onto the track, and every slide grinds a little more metal away. We replace the roller assemblies in pairs, adjust the height so the door hangs square in the frame, and clean and straighten the track underneath so the new rollers don’t wear out early.
Patio Door Glass Replacement
A cracked pane or a fogged, failed seal doesn’t mean the whole door goes. We re-glaze patio doors in place with tempered or insulated glass units matched to the original, which keeps the frame, the hardware, and the finish you already have.
Sliding Glass Door Replacement & Patio Door Replacement
There’s a point where repair stops making sense — a rotted timber frame, a bowed aluminium track, a unit so old that no rollers are still made for it. That’s when sliding glass door replacement is the honest answer, and we’ll tell you when you’ve reached it rather than selling you a repair that buys six months.
A replacement is a same-day job in most homes. We remove the old unit, clear and clean the sill track, check the opening for square and rot, and set the new sliding patio door with fresh flashing, insulation, and seals. You get a door that locks properly, slides with one finger, and actually keeps the weather out.
Signs Your Sliding Patio Door Needs Attention
- The door needs two hands, a shoulder, or a running start to move
- Grinding, scraping, or rumbling along the track
- The door drags on the sill or sits visibly crooked in the frame
- Condensation or fog trapped between the panes
- The latch no longer lines up with the keeper
- A noticeable draught, or daylight visible at the frame edge

Frequently Asked Questions
Can a sliding glass door be repaired instead of replaced?
Usually, yes. Rollers, tracks, handles, locks, weatherseal, and glass are all replaceable individually. Replacement of the whole unit is normally only necessary when the frame itself has rotted, corroded, or bowed out of shape.
Do you replace just the glass in a patio door?
We do. If the frame and hardware are sound, we re-glaze the existing door with a matched tempered or insulated unit and leave the rest of the door in place.
How long does a sliding patio door replacement take?
A straightforward like-for-like replacement is typically a half-day job. If the opening needs reframing, or if you’re going from a smaller opening to a larger patio door, allow a full day.
Do you work on interior sliding glass doors as well as exterior ones?
Yes — interior sliding glass doors, room dividers, and closet sliders all use the same roller-and-track principles, and our technicians service all of them.
