New Installation vs. Replacement
Replacement means a new unit goes into an existing opening. New installation means creating or changing an opening: cutting in a window for a darker room, widening a wall for a sliding door, or fitting units in an addition. New installation involves framing, a properly sized header, sheathing repairs, flashing and exterior and interior finish work, so it takes more time and planning.
Realistic Timelines
Client-stated estimates for typical Terry homes:
- Whole-house window replacement: about 2 to 4 days
- New window installations with structural changes: about 3 to 5 days
- Door replacement: roughly 4 to 6 hours per unit
- New door installation with framing work: about 1 to 2 days
- Combined window and door projects: about 3 to 7 days
Weather and any hidden rot can shift these, and we'll keep you posted.
Doing It in Phases
You don't have to replace every opening at once. Many homeowners start with the worst windows, often on the sunniest side of the house, or with the front door, then finish the rest later. We'll note which units to match so the second phase looks consistent with the first. Our Terry exterior services page lists the other projects you might combine with window work.
Materials That Suit Central Mississippi
Long, humid summers favor frames that don't swell or rot. Vinyl is economical and low-maintenance; fiberglass handles heat with minimal movement; wood-clad offers a classic interior. Pair any of them with low-E glass to block solar heat. For doors, fiberglass entry systems resist moisture far better than solid wood.
Simple Upkeep After Installation
- Clean tracks and weep holes so water drains freely
- Wash glass and frames with mild soap a couple of times a year
- Check exterior caulk and door sweeps annually
- Lubricate hinges, locks and rollers as needed

Common Questions
What's the difference between window installation and replacement?
Replacement puts a new window into an existing opening. Installation creates or changes an opening, which requires framing, a header and more finish work. Installation generally takes longer and costs more.
How long do window and door projects take in Terry?
Whole-house replacements usually take 2 to 4 days, new window installations 3 to 5 days and door replacements 4 to 6 hours each. Combined projects typically run 3 to 7 days.
Can I replace windows and doors in stages?
Yes. Many homeowners start with the windows in the worst shape or the front door and do the rest later. We document styles and colors so later phases match.
What maintenance do new windows and doors need?
Very little: keep tracks and weep holes clear, wash frames and glass occasionally, and check caulk, sweeps and hardware once a year.
