Door & Window Installation
Entry doors, interior doors, patio doors, and replacement windows installed square and sealed
A premium take on door & window installation
A door or window is only as good as its install. Out-of-square openings, missing flashing, and gaps stuffed with the wrong insulation are why new units still stick, leak, or let drafts in. NMG Construction removes the old unit, checks and corrects the rough opening, sets the new door or window plumb and level, flashes and seals it against Indiana weather, and finishes the trim inside and out. We install exterior entry doors, storm doors, sliding and French patio doors, interior doors, and replacement windows.
This service is a good fit for homeowners and property managers who want a clean, professional result without juggling the details themselves. We handle the prep, the finish work, and the cleanup so the space is ready to enjoy when we're done.

- Exterior entry, storm, and patio doors
- Interior doors, prehung or slab
