Casement Windows Installation
Professional Casement Window Installation Services
AG Window Service installs and replaces casement windows across Garland and the Dallas–Fort Worth metro. A crank swings the whole sash outward on a side hinge, and the sash pulls tight against a compression seal when you close it.
That makes them a strong choice for rooms where air sealing matters most, and for catching a breeze that runs across the face of the house rather than straight at it. The sash swings out, so they are a poor fit over a walkway, patio path or anywhere the open sash would be in the way.
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
Because the whole opening clears, a casement ventilates better per square inch than any other style. We measure every opening on site, because a casement window ordered to a stock size and forced into an out-of-square opening will never seal properly.

Upgrade to casement windows fitted by a family-owned crew based in Garland — measured to your openings, sealed correctly, and finished clean. Most jobs wrap in one to two days.
How it works (Our process)
Keep the hinge track clean and the crank mechanism lubricated. That is most of the maintenance.
1. Get a Free Estimate
Call or message us and we will come and measure. Casements take a little longer to hang than a slider because the sash has to be set square for the compression seal to close evenly. Getting that right is the whole point of the style.
2. Schedule Your Service
Approve the quote and your casement windows are built to the measured sizes. Casements are often used on one elevation only — the windward side, or wherever airflow matters most — so replacing a subset is common and sensible.
3. Enjoy Hassle-Free Installation
On the day we protect the interior, remove the old units, fit and seal the new casement windows, and take all the old material away with us.

Frequently Asked Questions
How long does it take to install replacement windows?
Casements take a little longer to hang than a slider because the sash has to be set square for the compression seal to close evenly. Getting that right is the whole point of the style. 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?
Casements are often used on one elevation only — the windward side, or wherever airflow matters most — so replacing a subset is common and sensible. 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 casement that no longer pulls tight usually needs hinge or crank attention rather than a new window. If the glass itself is fogged, the sealed unit is done. The sash swings out, so they are a poor fit over a walkway, patio path or anywhere the open sash would be in the way.
Will replacement windows increase the value of my home?
Because the sash clamps against a compression seal, a closed casement is the most airtight operating window you can buy. On a windy elevation that is a measurable difference. Because the whole opening clears, a casement ventilates better per square inch than any other style.
What types of windows and doors can I get?
We fit casement 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 casement when air sealing and ventilation matter most, and when nothing outside the window will be in the path of the swinging sash. A crank swings the whole sash outward on a side hinge, and the sash pulls tight against a compression seal when you close it.
What are the most energy-efficient window and door materials?
Vinyl and fiberglass both perform well in casement 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.
