The line items every quote should show
Ask each company to itemize their bid using these categories. If a company won't break it down, that's information too.
- Door unit itself: brand, model, material, and glass package
- Removal and disposal of the old door and frame
- Framing and sill repair, included, or billed as found
- Sill pan, flashing, and threshold
- Brick mould or exterior trim, and interior casing
- Insulation and sealing around the frame
- Hardware and lockset, including any multipoint lock upgrade
- Paint or stain finish
- Permit costs, if applicable
- Labor warranty term, separate from the manufacturer's product warranty
Why the lowest bid isn't automatically the best deal
A bid that's dramatically lower than the others is usually missing something, most often framing repair contingency, a real sill pan and flashing detail, or a hardware allowance. That missing scope doesn't disappear, it shows up later as a change order once the old door is off the wall, or as a door that doesn't seal properly two winters from now.
What a fair price range looks like
For a standard entry door replacement into a sound opening, expect $1,200-$4,500 depending on material and glass. If your quote is well below that range for a comparable fiberglass or wood door, ask specifically what's excluded before assuming it's a good deal.

ROI benchmarks cross-checked against (Cost vs. Value, 2024). Not a quote; actual bids depend on your specific doors and frame condition.

Frequently asked questions
How many door quotes should I get?+
Two to three for entry, patio, or storm door replacements is typically enough to spot outliers and confirm a fair market range. Interior door swaps with straightforward scope often need only one detailed quote.
Should I choose the installer with the best warranty over the lowest price?+
A strong labor warranty (not just the manufacturer's product warranty) is worth paying a bit more for on doors, since improper installation is the most common cause of drafts, sticking, and premature hardware failure, not the door itself.
What if one quote includes a lifetime warranty and another doesn't mention one at all?+
Ask exactly what the lifetime warranty covers, materials only, or materials and labor, and whether it's transferable if you sell the house. Some 'lifetime' warranties are prorated after the first several years, so get the details in writing.
