Replacing One Entry Door & One Window
Nashville, TN (Davidson County) · 2026 estimate · like-for-like, no opening resize
Bottom line: For a straight swap of one standard front door and one same-size
double-hung window, the cheapest reliable route is a well-reviewed specialty installer or a
qualified handyman. We almost certainly don't need a permit, and we only
legally need a licensed contractor if the whole job crosses $3,000.
Plan on roughly $1,600–$2,200 all-in for both.

Each number is product (the door/window unit) plus installation labor. The high end is where
fancier doors, glass inserts, sidelights, or wood/upgraded windows live.
Window breakdown well-supported
- Unit/product: ~$250–$1,000 (vinyl cheaper, wood/composite higher)
- Labor: ~$100–$500 (two installers, about an hour for a ground-floor window)
- All-in: ~$350–$1,500, typically around $600–$650
Door breakdown moderate confidence
- Unit/product: ~$300–$1,500 for a standard steel or fiberglass prehung door
- Labor: ~$230–$700 for a straightforward like-for-like swap (Nashville labor runs ~7% below the national average)
- All-in: basic from ~$450–$1,230; typical mid-range ~$1,000–$1,500
How we should hire it out
- Specialty window/door installer — usually the sweet spot. They supply the unit, install it, and carry both product and labor warranties. Get 2–3 quotes.
- Handyman — lowest-cost pro route for a small job like this. Legal as long as the total stays under $3,000. Vet reviews and ask specifically about flashing/sealing.
- DIY — doable for a confident DIYer; you pay only for the units. Main risk is water leaks from imperfect sealing and a door that isn't hung plumb.
- General contractor — overkill unless we find rot/damage behind the old door or window, resize an opening, or the house is in a historic district.
Suggested move: Get 2–3 quotes from local specialty installers plus one or two
well-reviewed handymen. Go with the installer if the price difference is small (warranties are worth it);
go with the handyman if their reviews are strong and we want to stay under $3,000.
The rules that matter (Nashville-specific)
- Permit: Not needed for a like-for-like swap. Metro Nashville only requires a permit if you change a window's size or style or alter the opening structurally.
- The $3,000 line: In Davidson County, a job valued at $3,000–$24,999 legally requires a contractor with a Home Improvement License. Under $3,000, an unlicensed handyman is fine.
- "Total" means materials + labor combined — the entire price of the contract, not just the materials. One contractor doing both the door and window counts the whole thing together.
The trick to staying under $3,000: If we buy the door and window units ourselves and
only pay a handyman for labor, then their contract is just the labor — which keeps that
number well under the threshold. We take on the risk of the products that way, but it's a legitimate route.
Before we commit — quick checklist
- Is our address in a historic overlay district? If so, it needs a Preservation Permit and approved materials regardless of cost. Check Metro's historic zoning map.
- Will the combined job cross $3,000? Decides whether we legally need a licensed contractor.
- Any hidden rot? Peek behind the trim/sill. Water damage turns a simple swap into a bigger job.
- Get "like-for-like, same opening" in writing so no permit gets triggered.
