Double-Hung Windows Installation
Professional Double-Hung windows Installation Services
AG Window Service installs and replaces double-hung windows across Garland and the Dallas–Fort Worth metro. Both sashes slide vertically, and both tilt inward, so you can clean the outside of an upstairs window while standing in the room.
That makes them a strong choice for bedrooms and any room needing an egress-sized opening, and for matching the original look of older DFW homes. Because the sashes overlap, the very top and bottom of the opening give you slightly less clear glass than a fixed unit.
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
Opening the top sash lets hot air escape near the ceiling while the bottom stays shut – useful with children or pets in the room. We measure every opening on site, because a double-hung window ordered to a stock size and forced into an out-of-square opening will never seal properly.

How it works (Our process)
Tilt both sashes in and wipe them down twice a year. The balances are the part that eventually wears, and they are replaceable.
1. Get a Free Estimate
Call or message us and we will come and measure. Double-hung units drop into the existing opening quickly once the old sash and balances are out — the balances are the fiddly part, and they are what we set carefully so both sashes hold position.
2. Schedule Your Service
Approve the quote and your double-hung windows are built to the measured sizes. Double-hung is the most common style in older DFW homes, so matching a few new units to existing ones is usually straightforward. We match sightlines and sash proportions.
3. Enjoy Hassle-Free Installation
On the day we protect the interior, remove the old units, fit and seal the new double-hung windows, and take all the old material away with us.

Frequently Asked Questions
How long does it take to install replacement windows?
Double-hung units drop into the existing opening quickly once the old sash and balances are out — the balances are the fiddly part, and they are what we set carefully so both sashes hold position. 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?
Double-hung is the most common style in older DFW homes, so matching a few new units to existing ones is usually straightforward. We match sightlines and sash proportions. 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 double-hung that will not stay up has failed balances, which is often repairable. Fogging between the panes is not — that is a dead seal. Because the sashes overlap, the very top and bottom of the opening give you slightly less clear glass than a fixed unit.
Will replacement windows increase the value of my home?
Two operating sashes mean two seals, so weatherstripping condition matters more here than on a fixed unit. Modern double-hungs seal far better than the 1970s versions they usually replace. Opening the top sash lets hot air escape near the ceiling while the bottom stays shut – useful with children or pets in the room.
What types of windows and doors can I get?
We fit double-hung 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 double-hung when you want the classic look, tilt-in cleaning, and an opening that meets egress requirements for a bedroom. Both sashes slide vertically, and both tilt inward, so you can clean the outside of an upstairs window while standing in the room.
What are the most energy-efficient window and door materials?
Vinyl and fiberglass both perform well in double-hung 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.
