What Exterior Door Replacement Costs, and What Moves It
What this comes down to
- The federal tax credit for exterior doors covered nothing installed after December 31, 2025.
- Labor never qualified for that credit in the first place, only the door unit itself did.
- A door swap needs no Carol Stream permit while the opening keeps its size and its location.
- Swapping the slab alone is the cheapest route, and it only works on a square, sound frame.
- A prehung unit costs more because it brings a new frame, sill and weatherseal with it.
- Widening an opening turns a door job into framing, with a new header and a new load path.
An exterior door replacement in DuPage County starts at $695 installed. A front entry door starts at $1,295. The gap between those two numbers is mostly the door itself, and very little of it is labor.
What follows gives a starting price for each kind of door job and what moves each one. It also covers the permit rule in Carol Stream and the energy rating that matters in Illinois. The federal credit that used to apply has now expired.
What does an exterior door replacement cost?
A standard exterior door starts at $695 installed, and a front entry door starts at $1,295. Most jobs land somewhere between those two figures. The unit on the truck is what moves the number, not the hours spent fitting it.
Three things sit inside that price. There is the door unit, the labor to hang and seal it, and the trim that finishes the opening. Only the first of those three swings by thousands of dollars.
A builder grade steel door and a solid fiberglass entry unit take almost the same time to hang. The carpentry either side of them is close to identical. What differs is the price on the showroom tag.
Every figure on this page covers a standard opening in a wood framed wall. Wider units, sidelights and glass panels all sit above it. The full range of work on entry doors begins from that same baseline.
Why does the size of the opening decide the price?
Because the opening is what turns a one day swap into carpentry. A door that drops into the frame already there is the cheap version. A door that needs a new opening is a framing job with a door at the end of it.
Three scopes exist and they price very differently. A slab swap reuses the frame. A prehung unit replaces the frame. A new opening replaces the framing around the frame as well.
The International Code Council sets the floor for what an exit door has to measure. Its residential code puts the minimum clear width at 32 inches and the clear height at 78 inches.
Most houses in DuPage County already meet that comfortably. The openings that do not are usually old side entries and basement doors. Bringing one up to size means a wider header and new trimmer studs underneath it.
Does replacing a door need a permit here?
Not in Carol Stream, as long as the opening keeps the same size and stays in the same place. That single condition is the whole rule. Change the opening and the answer flips the other way.
The Village of Carol Stream publishes a list of residential work that needs no permit at all. Window and door replacement sits on that list, provided the opening is unchanged.
Cutting a new opening is a different animal. It is structural work, so it needs a permit and a header sized for the span. An inspection follows at the end. Budget for the fee and the wait alongside the carpentry.
Other towns in the county draw the line in the same place but publish it differently. Checking before the door is ordered costs nothing at all. Starting without a required permit can bring added fees and a fine.
Does an energy rating change what a door costs?
Yes, and this is one of the few places where paying more is measurable afterward. A door's U-factor states how much heat passes through it. Lower is better, and Illinois sits in the coldest rating zone.
ENERGY STAR sets the thresholds. The ratings behind them are certified by the National Fenestration Rating Council. In the Northern zone an opaque door qualifies at a U-factor of 0.17 or lower.
A door with glass in it is judged differently. A half lite door has to reach 0.23, and a mostly glass door 0.26. So the glass that makes an entry look expensive also makes the rating harder to hit.
The federal credit that used to soften this has gone. The Internal Revenue Service capped it at 30 percent of the door, up to $250 each. It covered nothing placed in service later than 2025.
Labor never counted toward that credit in any case. The detail surprises people, because installation is often half the bill on a door. Any quote from 2025 that leaned on the credit is out of date now.
What does each door job start at?
These are starting prices for door work in DuPage County, not quotations. The wider market column carries 2026 Chicago area cost data. It sits there so that each figure can be read against something else.
| The work | Starting price | Wider market | What moves it |
|---|---|---|---|
| Exterior door replacement, installed | From $695 | $800 to $2,500 | Whether the existing frame is reused, and how wide the unit is |
| Front entry door replacement | From $1,295 | $1,500 to $4,500 and up | The door itself, plus sidelights, glass and any hardware upgrade |
| Storm door replacement, installed | From $295 | $350 to $850 | Opening size, closer type, and whether the brickmould is sound |
| Storm door repair | From $125 | $150 to $400 | Hinge, closer or frame, and whether the part is still made |
| Sliding or patio door repair | From $175 | $200 to $700 | Roller condition, track wear, and whether the glass unit has failed |
| Major sliding door repair | From $395 | $500 to $1,200 | How far the track has worn, and whether the sill below it has dropped |
Every figure above is a starting price rather than a quote. Soft timber found around an opening is priced separately, as structural rot repair. Nothing of that kind gets absorbed quietly.
What cannot be priced over the phone?
Whether the frame can stay. A frame that looks sound from the outside can be soft at the sill. That is the commonest single reason a slab swap turns into a prehung unit.
What the opening has been doing. Older openings settle, and a door that closes today may not close against a new frame. Squaring one is carpentry rather than fitting.
What sits behind the brickmould. Sheathing, housewrap and flashing stay hidden until the trim comes off. Wet sheathing changes both the job and the number on it.
How the sill meets the floor. A threshold bearing on soft subfloor has to be dealt with first. None of that work shows up in a photograph.
All four get checked on site before any figure goes in writing. That is why an estimate involves lifting trim rather than studying a phone picture. Homeowners describe the difference in their own words.
Exterior door replacement questions
How much does it cost to replace an exterior door?
A standard exterior door starts at $695 installed in DuPage County. A front entry door starts at $1,295. The wider Chicago area market runs from $800 to $2,500 for a standard unit. The door itself, rather than the labor, is what moves that figure up or down.
How does Perfect Work decide between a slab swap and a full replacement?
Perfect Work Remodeling & Repairs lifts the trim before quoting. The jamb legs, the sill and the subfloor all get checked. A slab swap is offered only where the frame is square, dry and sound. Anything soft at the sill moves the job to a prehung unit, and the reason goes in the estimate.
Do I need a permit to replace my front door?
Not in Carol Stream, provided the opening keeps its existing size and location. A like for like replacement sits on the village list of work needing no permit. Cutting a wider opening is structural work and does need one, together with an inspection.
Is it cheaper to replace just the door and keep the frame?
Yes, when the frame deserves to be kept. Reusing a square, dry frame takes the trim work and the weatherproofing out of the job. A soft sill or a settled opening cancels the saving. A new door will not seal against a frame that is out of true.
What does an exterior door estimate from Perfect Work cover?
The visit, the measure and the written figure carry no charge. Perfect Work Remodeling & Repairs prices the door, the fitting, the trim and the seal together. That is one number rather than a list of line items. Anything found behind the trim is requoted before work continues.
Does a new exterior door still qualify for a tax credit?
No, not for anything installed now. The federal energy credit for exterior doors ran through 2025 only. It was capped at $250 per door and $500 in total. It never covered the labor to fit one, which is often half the bill on a door job.
Getting a real number before the door is ordered
Most door calls start with a photograph and a guess about the frame. A measure takes about twenty minutes. It settles the scope, the price and the lead time in one visit, and nothing is charged for it.
A visit from Perfect Work Remodeling & Repairs means the trim comes off where the sill is suspect. Nobody quotes a door from the driveway. Anything found underneath is requoted in writing before the work goes on.
Larger work books as general repair work, and a single door books as one visit with a written scope. Storm doors and patio doors are quoted the same way. The full range sits under everything handled here.
