We’re Meridian Windows and Doors Dallas, part of the Garrison Partners family and held to The Garrison Standard since 2009. Elliot Vance leads our Dallas crews, and every technician who walks through your door is background-checked and uniformed. A meridian is a fixed line you measure everything against, and that is what the name means and how we run every install. We don’t quote low and add on later. The price goes on paper first, and it does not move at the door.

Patio Door Repair

Patio Door Repair brings a sliding or hinged patio door back to proper function when rollers fail, tracks bend, or weatherstripping tears away. In Dallas, patio door repair typically runs $180 to $450 for roller replacement, realignment, and hardware fixes, while track resurfacing or full frame correction can push toward $850. Meridian Windows and Doors Dallas diagnoses the exact point of failure before quoting a fix, so you pay for the repair that solves the problem, not a menu of guesses.

Roller and Track Service

Dust and grit from Dallas construction settle into sliding door tracks and grind rollers down over time. We remove the panel safely, inspect roller assemblies, clean the track channel, and replace worn components with manufacturer-matched parts. The door should glide with one hand by the time we’re done.

Weatherstripping and Seal Replacement

Dallas summers push hot air against door seals daily, and worn weatherstripping shows up first as a draft near the jamb. We strip out the old material and install new compression seals that match the door’s profile. This keeps conditioned air inside where it belongs and cuts the dust that blows in during spring storms.

Sliding Door Repair

Sliding Door Repair addresses the two most common failures we see in Dallas homes: a door that sticks or grinds when you push it, and a door that has fallen out of square so the lock no longer engages. Most sliding door repairs run $150 to $500 depending on whether we’re replacing rollers, adjusting the frame, or resurfacing a bent track. We stock OEM parts for Therma-Tru and Mr-Glass units, which keeps turnaround short on common models.

Alignment and Lock Correction

A sliding door that won’t lock is a security problem, not an annoyance. When the panel sags from a loose roller carriage, the latch misses the strike plate. We reset the panel height, square the door in the frame, and test the lock engagement before we call the job done.

Sticking and Grinding Diagnosis

If your door takes a shoulder to move, the cause is usually a collapsed roller or a track channel caked with debris. Some contractors will spray lubricant and leave. We open the track, inspect the roller wheels, and replace the part that actually failed. Lubricant over a broken roller just hides the problem for a few weeks.

Patio Door Replacement

Patio Door Replacement swaps out an old or failed door for a new unit that fits the existing opening. In Dallas, a standard sliding patio door replacement runs $1,000 to $3,200 including the door, installation, and haul-away of the old unit. When rot is found in the surrounding frame, the cost can reach $4,500 with structural repair. Meridian Windows and Doors Dallas pulls a written price for the full job before the first screw comes out.

Frame Rot and Structural Repair

Dallas sees heavy spring storms, and patio door frames that weren’t flashed correctly absorb water for years before anyone notices. When we remove an old door and find rot in the subfloor or king studs, we stop and show you exactly what we found. The repair gets quoted separately, in writing, before we proceed, and we don’t restart work until you approve it.

Energy-Efficient Door Upgrades

Replacing a single-pane patio door with a low-E glass unit (a thin coating that reflects heat while letting light through) changes how a room feels in August. We spec insulated frames and Low-E glazing from our eight manufacturer lines, and the door gets sized to the actual opening, not the closest one in a warehouse. A new door that fits correctly is the whole point.

Sliding Door Replacement

Sliding Door Replacement is the installation of a new sliding panel system when the existing door is beyond repair or the homeowner wants upgraded glass and framing. In Dallas, sliding door replacement runs $1,200 to $3,600 for standard two-panel units and $3,000 to $6,500 for three-panel or premium frame systems. The variables are glass package, frame material, and whether the opening needs correction.

Glass and Frame Package Selection

The right glass package for a Dallas home balances heat rejection with natural light. We walk through the options from manufacturers like PGT and CGI, which build impact-rated frames for storm-prone regions, and ES Windows, which carries thermally broken aluminum in clean sightlines. The spec sheet gets written down, and the price follows the spec, not the other way around.

Panel Weight and Hardware Upgrades

A heavier multi-point locking door demands a stronger roller system than the original hardware may have handled. We upgrade the carriage and track assemblies to match the new panel weight, which is where a lot of sliding door replacements fail. Undersized rollers wear out in a season. We don’t let that happen.

Sliding Door Installation

Sliding Door Installation covers new-construction or addition openings where no door currently exists, including retrofits where a window is converted to a door. In Dallas, sliding door installation with new framing runs $1,800 to $5,000 depending on header work, exterior finish matching, and whether a permit is required for the structural change. Meridian Windows and Doors Dallas handles the permit paperwork and schedules the inspection.

Header Framing and Structural Requirements

When a window becomes a sliding door, the wall above needs a proper header to carry the load. We frame to current Dallas code, post the permit, and call for the inspection before the drywall goes back up. The Garrison Code applies to every cut: clean job site, no shortcuts under the sill, no trim left unfinished.

Exterior Finish Matching

Installing a sliding door means tying the exterior finish into brick, stucco, or siding so the opening looks original. We match flashing, trim profiles, and caulk lines to your existing exterior, and we don’t leave caulk beads smeared like an afterthought. The sill caulk line is a straight one, and it stays that way.

Brands We Service

We install and replace Therma-Tru patio door systems regularly, and our technicians are trained on their fiberglass frame lines, which hold up well against Dallas heat and humidity. The fit matters: Therma-Tru frames require precise shimming at the jamb, and that’s the difference between a door that swings true and one that binds in a season.

We also work with Mr-Glass and ECO Window Systems. Mr-Glass produces solid vinyl patio door frames that make sense for mid-range Dallas homes, and ECO Window Systems builds impact-rated units that handle severe weather without a bulky look. There are eight manufacturer lines in our portfolio, so the door we spec is the one that matches your opening and your budget, not one that happens to be in the back of a truck. Whether you have one of those brands or any other make, we can help.

Signs You Need a Pro Right Now

• The door comes off its track without warning. A patio door that jumps the track can fall, and a falling glass panel is dangerous. If your door has slipped the track more than once, the roller assembly is failing and needs replacement before the glass breaks or someone gets hurt.
• You feel a draft standing five feet away. That means the weatherstripping is gone or the door is so far out of square that gaps have opened at the jamb. In a Dallas summer, that draft is air you paid to cool leaking outside. In winter, it’s cold air driving your heating bill up.
• The lock no longer engages. A patio door that can’t be locked is a security weak point on the back of your house. The cause is usually sagging rollers or a bent frame, and the repair is cheaper than what a thief might cost you.
• Condensation sits between the glass panes. That means the seal has failed and the insulating gas has leaked out. The glass will never be clear again, and the door’s energy performance is gone. Replacement glass or a full door replacement is the fix.
• Water stains appear at the bottom corners after rain. Water intrusion at the sill means the door’s flashing or weather seal has failed. Left alone, it rots the subfloor, and that repair costs far more than a sill correction done now.

Our Process, Step by Step

1. 1
   Site measurement and opening check. We measure the actual opening at the top, middle, and bottom, then check for level and square. Most openings are not perfect, and the measurement tells us what’s needed. You get a written price based on those exact dimensions.
2. 2
   Written quote with line items. The quote lists the door, hardware, labor, haul-away, and any frame correction as separate lines. No lump sums you have to trust. This is the no-hassle upfront pricing: the price goes on paper before any work starts, and it does not move at the door.
3. 3
   Removal and structure inspection. We pull the old door and open the rough opening. If there’s rot or the header is undersized, we show you and quote the correction before proceeding. This is where most contractors bury surprise fees. We don’t.
4. 4
   Installation, leveling, and sealing. The new door gets shimmed, leveled, and secured to the framing. We install new flashing, set the door in the opening, and run a clean seal along the jamb. Every door is installed to The Garrison Code: no shortcuts, no missing screws, no caulk smeared like an afterthought.
5. 5
   Operation test and cleanup. We open and close the door, test the lock, and check the sweep for daylight. The job site gets swept and the old door gets hauled away. Before we leave, you walk the door with our technician and we run through the operation, the warranty, and the care instructions.
