Sliding Windows Installation
Professional Sliding Window Installation Services
AG Window Service installs and replaces sliding windows across Garland and the Dallas–Fort Worth metro. One or both sashes roll sideways along a track. Nothing swings in or out, so the window stays entirely within the wall.
That makes them a strong choice for wide openings, rooms over a patio or deck, and anywhere reaching the window is awkward. The track collects dust and grit, which is the usual reason an older slider gets stiff. It is cleanable, not terminal.
Not sure this is the right style? Our Window Style Finder asks four questions about your opening and tells you which style fits, and why.
Experience the AG Window Service Difference
You get half the opening for airflow, but it is effortless to operate one-handed over a counter or sink. We measure every opening on site, because a sliding window ordered to a stock size and forced into an out-of-square opening will never seal properly.

I really enjoyed the service and communication from AG. They came out, measured my windows, gave me multiple options to help me make the best decision (which was awesome). Price was good and they beat their own timeliness. I would definitely use them again.
Frequently Asked Questions
How long does it take to install replacement windows?
Sliders are among the quickest installs — no hinges or balances to set, just a level track and a properly sealed perimeter. A single opening is often done in an hour or two. A full home is typically one to two days; custom sizes add order lead time rather than install time.
Should I replace all the house windows at once?
Sliders suit wide openings, so homeowners often replace the large living or patio-facing windows first and leave the smaller rooms for later. Doing a whole house at once costs less per window, but it is never a requirement.
Will I have a lot of cleaning up to do after the installation?
No cleanup falls to you. We protect the interior first and every old sash, pane and offcut leaves with our crew.
How do I know my windows and doors need replacing?
A stiff slider is usually a dirty or worn track and rollers, both replaceable. Condensation inside the glass is the sign that the unit itself needs replacing. The track collects dust and grit, which is the usual reason an older slider gets stiff. It is cleanable, not terminal.
Will replacement windows increase the value of my home?
A slider seals along the meeting rail rather than clamping shut, so the glass package does most of the efficiency work. Low-E is worth prioritising here. You get half the opening for airflow, but it is effortless to operate one-handed over a counter or sink.
What types of windows and doors can I get?
We fit sliding windows alongside double-hung, casement, sliding, awning, picture and bay or bow units, so we can tell you honestly if a different style suits the room better.
What factors should I be considering when buying windows and doors?
Choose sliding when the opening is wide, when nothing should protrude into a patio or walkway, and when easy one-handed operation matters. One or both sashes roll sideways along a track. Nothing swings in or out, so the window stays entirely within the wall.
What are the most energy-efficient window and door materials?
Vinyl and fiberglass both perform well in sliding windows. Fiberglass holds its shape better through Texas temperature swings; vinyl costs less and suits most homes. The Low-E glass package matters more than either.
