New construction window installation differs from replacement work because it involves setting windows into unfinished framing rather than fitting them into an existing structure, which gives us more control over alignment, weatherproofing, and long-term performance. Alabama's climate, with its humidity and temperature swings, makes this precision especially important.

New Construction vs. Replacement Window Differences
New construction windows have a nailing flange attached to the frame, which we secure directly to the wall sheathing before siding or brick goes on, while replacement windows fit into an existing frame, using the old structure to hold the new unit in place. We install new construction windows before exterior finishes are applied, which gives us full access to the rough opening and surrounding framing, letting us verify that openings are plumb, level, and square before the window ever goes in. We also have room to adjust flashing and insulation without working around finished walls, and because new construction windows attach to the sheathing, they typically create a tighter, more consistent seal than retrofitted units. We use this method for all new builds and additions we install.
Coordinating Installation With Builders & Framing Schedules
We work directly with builders and general contractors to schedule window installation at the correct point in the framing timeline — windows go in after the rough framing and roof are complete, but before exterior siding, brick, or stucco is applied. We confirm rough opening dimensions against window specifications before delivery to avoid on-site surprises, and our team communicates with framers ahead of time about rough opening tolerances (typically 1/2 inch larger than the window unit on each side), header height and sill plate placement, and any structural adjustments needed for larger or specialty window sizes. We stay in contact with the builder throughout the process, so scheduling conflicts and delays are minimized, which keeps the broader construction timeline on track.
Flashing & Moisture Barrier Best Practices
We install flashing in a specific sequence to direct water away from the window opening and down the exterior wall — sill flashing goes in first, followed by side flashing, then head flashing, each one overlapping the layer below it. We use self-adhering flashing tape at the corners and seams to prevent gaps where water could enter, and the weather-resistant barrier on the wall gets integrated with the window flashing so water sheds outward rather than behind the barrier. We also apply backer rod and sealant around the exterior of the frame after installation, creating a continuous air and water barrier between the window and the wall assembly, which we consider a critical step in preventing leaks and long-term moisture damage.
FAQs
Costs depend on window size, material, and how many units we're installing. Vinyl windows typically run less than fiberglass or wood-clad options.
We provide a detailed quote after assessing the wall openings and your material preferences. Labor costs also vary depending on whether we're working on a single-story home or a multi-level build with more complex access points.
A standard-sized window takes our crew about 1-2 hours to install once we're on site. For a full house with 15-20 windows, we usually complete the work in 2-4 days depending on weather and window count.
Larger custom sizes or specialty shapes can add time to the schedule. We coordinate with your builder's timeline so window installation lines up with the framing and siding phases of construction.
Birmingham gets hot, humid summers and occasional freezing temperatures in winter, so we recommend materials that handle both extremes well. Vinyl windows resist moisture damage and don't require repainting, making them a practical choice for many homeowners.
Fiberglass windows hold up well against temperature swings and offer more durability over time. Wood-clad windows provide a traditional look, but they need more upkeep in Birmingham's humidity compared to vinyl or fiberglass.
