Commercial Window Replacement for Texas Multifamily Buildings
Window and door replacement projects for occupied condos, apartments, and commercial buildings
Old windows that will not open properly, failed seals, and repeated water problems eventually make repairs a poor use of money. Shepperd Construction delivers commercial window replacement for multifamily and commercial properties across Texas, with each new window flashed into the wall correctly and the work phased so residents stay in their units.

Commercial window replacement removes existing windows or doors and installs new units, along with the flashing, sill pans, and sealant that tie them into the wall. On multifamily buildings, the installation details decide whether new windows perform for decades or start causing problems within a few seasons.
New Windows Are Only as Good as the Install
A new window can be well made and still let water in if it is set without a sill pan, flashed behind the water-resistive barrier, or sealed with the wrong joint. Many replacement projects fail at the perimeter, not the window itself, which is why the same units start causing trouble again a few years later.
We treat every opening as part of the wall. Old flashing and damaged sheathing are corrected while the opening is exposed, and each new unit is integrated with the barrier around it. Where the wider wall is failing, the window project can be combined with building envelope repair.
Integrated With the Wall
Each window is flashed into the barrier, with sill pans that drain to the outside.
Damage Fixed While Open
Damaged sheathing and framing found at the opening is repaired before the new unit goes in.
Unit-by-Unit Phasing
Openings are scheduled unit by unit, with temporary protection, so residents stay home.
Signs It Is Time to Replace Windows
Repairs make sense until the windows themselves are the problem. These are the usual signs:
- Windows not opening or closing properly across many units
- Fogged glass from failed insulated glass seals
- Frames that are cracked, warped, or corroding
- Repeated water problems at the same openings after repairs
- Outdated units driving comfort and energy complaints
- Hardware and parts that are no longer available
- Doors that no longer close, latch, or seal
If water at the windows is the main issue, start with window leak repair. Many openings can be fixed without full replacement.
Apartment and Condo Window Projects
Apartment window replacement and condo window replacement projects have one thing in common: people live behind every opening. We plan unit access with the manager or board, protect interiors during removal, and keep each opening weathertight until it is closed.
Many projects also include commercial door replacement, such as sliding patio doors, entry doors, and storefront doors on mixed-use buildings. Doors get the same sill pan and flashing details as the windows around them.
Who We Work With on Window Projects
Window projects involve several decision-makers. Each gets what they need to approve and plan the work.
Property Managers
Unit-by-unit schedules, resident notices, and one point of contact for access.
Commercial Window Replacement Services
Window projects cover the full opening, not just the glass. Most include several of these scopes.
Window Removal
Existing units removed with interiors protected and openings secured.
Opening Repairs
Damaged sheathing, framing, and flashing corrected while exposed.
Sill Pans
Pre-formed or built-up sill pans that drain water to the exterior.
Window Installation
New units set, shimmed, and anchored square so they operate properly.
Flashing Integration
Head and jamb flashing lapped correctly into the water-resistive barrier.
Perimeter Sealant
Exterior joints sealed with backer and sealant sized for movement.
Door Replacement
Patio, entry, and storefront doors replaced with the same details.
Interior Finishes
Drywall returns, trim, and paint completed around each new unit.
How a Window Replacement Project Runs
Window projects run unit by unit, so planning access matters as much as the installation.
We survey the openings and existing conditions and outline the replacement scope.
The board approves a scope, cost, and a unit-by-unit schedule.
Crews remove and install by unit, with temporary protection until each opening is sealed.
We walk finished units with the manager and hand over the project documentation.

Frequently Asked Questions
When the windows themselves are failing: frames cracked or warped, insulated glass fogged across many units, hardware no longer available, or water problems returning at the same openings after repairs. If the windows are sound and the problem is the joint or flashing around them, repair is usually the better value.
Worn balances and hardware, warped or swollen frames, and building movement can all stop windows from operating. One window is usually a hardware fix. The same problem across many units often points to aging windows or movement in the structure, and it is worth a closer look.
Yes. Work is scheduled unit by unit, residents get notice before crews arrive, interiors are protected during removal, and each opening is kept weathertight until the new unit is sealed.
A sill pan is a waterproof tray under the window that catches any water getting past the window and drains it back outside. Without one, that water goes into the wall below. Many older multifamily buildings were built without sill pans, which is a common cause of hidden damage.
Yes. Window projects often include sliding patio doors, entry doors, and storefront doors. Each gets the same sill pan, flashing, and sealant details as the windows around it.
It depends on the number of openings, the window type, access, and how units can be scheduled. We set a unit-by-unit schedule during planning and keep the manager and board updated as it progresses.
Cost depends on the window and door types, the number of openings, the condition found behind the old units, access, and interior finish work. We survey the building first and give the board a defined scope and cost.
We serve properties across Texas, with teams in Dallas, Fort Worth, Austin, and San Antonio.
