What a double front-entry replacement costs installed
Hynes Construction's 2026 Main Line, Pennsylvania table lists $3,500–$10,000 installed for French entry doors described as “double door, fiberglass.” Its single fiberglass entry category is $1,500–$4,500 installed. Both are regional contractor planning ranges per entry assembly. The double range prices the pair, rather than each panel separately.
Angi's national door-installation guide, updated September 23, 2026, gives $750–$5,000 for double-door installation, including materials and labor. Its category mixes double-door projects; it does not isolate premium front entries. That makes Hynes' explicitly identified fiberglass front-entry row more closely scoped to this purchase, while Angi supplies broader context.
This page covers a hinged front entrance with two door leaves. For the general replacement process, see the entry-door replacement cost guide. For patio assemblies and French-style sliding alternatives, see the French-door cost guide. Specify where the proposed pair will be installed before comparing it with a price labeled only “French door.”
Double versus single: keep the source and material attached
The current regional table gives a direct fiberglass category comparison and single-entry context for steel and wood. It supplies no double-steel or double-wood row; those prices need actual bids.
| Published entry category | Main Line PA installed range per entry | Material | Scope variables identified by Hynes |
|---|---|---|---|
| Single steel entry | $1,200–$3,000 | Steel | Door grade, glass, hardware, frame condition, trim |
| Single fiberglass entry | $1,500–$4,500 | Fiberglass | Door grade, woodgrain finish, glass, hardware |
| Single solid-wood entry | $2,500–$8,000 | Wood | Species, panel design, finish, hardware |
| French entry, double door | $3,500–$10,000 | Fiberglass | Material, glass, hardware, astragal type |
Source: Hynes' visible “Cost Range Installed” table, labeled 2026 and retrieved September 30. Its single-entry rows specify standard 36×80 doors. The double row does not identify a standard pair size or a particular manufacturer. The page supplies no separate publication date for the table. Its earlier material-comparison table and French-entry paragraph use different ranges; the figures here consistently come from the explicitly labeled 2026 cost table, rather than mixing those estimates.
Subtracting either endpoint of the single range from an endpoint of the double range would create an upgrade charge the contractor did not publish. Ask for alternatives using the same finish, glass, installation company, and opening conditions. Have the estimator identify the complete installed scope for each alternative before deciding whether the extra operating leaf is worth its quoted difference.
Why the national guides disagree
Angi's September 2026 style table lists standard single installation at $200–$1,800, beside its $750–$5,000 double category. The source expressly warns that exterior double doors in a load-bearing wall can exceed its range. Neither category establishes the cost of widening your front wall.
For historical context, HomeGuide's visibly dated September 12, 2024 guide separates the purchase into material, labor, and total columns:
| HomeGuide's historical category | Material per entry | Labor per entry | Total installed per entry |
|---|---|---|---|
| Single entry | $200–$2,000 | $130–$750 | $330–$2,750 |
| Double entry | $400–$8,000 | $500–$1,100 | $900–$9,100 |
Source: HomeGuide, “Cost To Install A Door By Type”. These are older publisher estimates, retained with their visible date rather than relabeled as newly collected 2026 prices. The material column is not an installed quote.
The spread has identifiable limits: Angi groups door styles broadly; HomeGuide separates entry types but uses older figures; Hynes specifies a regional fiberglass pair. They do not describe the same supplied product or project. Compare your bid against its own specification first. A price near a national guide's upper end can still omit finish restoration, while a higher complete quote can include work that the guide never itemized.
Replace an existing pair or enlarge a single opening
Begin with an existing-condition drawing. Have the bidder mark the current frame, opening dimensions, threshold, trim, and anything it intends to retain. For a pair replacing a pair, ask whether both slabs and the complete frame are removed. For a single entrance becoming a double entrance, request a separate description of the wall alteration.
Angi's double-door discussion identifies load-bearing wall work as a reason its installed range can be exceeded. That supports asking who evaluates the structure, who supplies any required design, and who restores the disturbed wall. It does not provide a fixed enlargement allowance to add to a door price.
Keep product measurement and structural measurement separate. Ask the supplier for the assembled frame size and required rough opening for the exact pair. Have the contractor confirm that proposed opening against the actual wall. Avoid ordering from the sum of nominal leaf widths: request the manufacturer's assembly drawing and the installer's accepted dimensions instead.
Have the contract state who handles applicable approvals and when the product may be ordered. If concealed conditions must be assessed after removal, agree beforehand on photographs, the revised scope, and authorization of additional work. That procedure belongs beside the known installed total so an opening change cannot drift into an undefined repair promise.
Three named material options, with actual warranty differences
The manufacturer documents below describe construction and coverage. They contain no matched installed price for these named lines. ProVia's catalog expressly offers its French-door configuration in Signet fiberglass and Legacy smooth steel; request dealer confirmation of the selected design. Simpson's documents describe the wood leaf; have its dealer specify the complete paired assembly and hardware.
| Documented property | ProVia Signet fiberglass | ProVia Legacy smooth steel | Simpson Nantucket Collection wood |
|---|---|---|---|
| Material/construction | Fiberglass; dovetailed and glued stile/rail construction | 20-gauge steel; steel tab-and-slot construction | Two-piece laminated stiles/rails; mortise-and-tenon joinery |
| Leaf thickness documented | 1-3/4 inches | 1-3/4 inches | 1-3/4 or 2-1/4 inches offered |
| Pair configuration evidence | French-door option in manufacturer catalog | French-door option in manufacturer catalog | Data sheet describes leaves; dealer must specify paired frame and hardware |
| Qualifying basic-door warranty | Lifetime while purchaser owns and lives in the single-family home; conditions apply | Same qualifying basic-door term | Ten years from shipment for specified species and qualifying application |
| Finish distinction | Factory slab finish: 15 years for stated defects | Factory slab finish: 10 years for stated defects | Warranty excludes performance or appearance of applied finishes |
| Transfer distinction | Basic-door warranty transferable once under the stated process | Same basic-door transfer provision | Ten-year Nantucket term is not transferable |
| Order judgment | Match the selected stain or paint to the supplied astragal finish | Specify the smooth-steel pair and exact frame | Require a separate frame, finishing, and hardware schedule with the wood order |
Sources: ProVia entry-door catalog, printed pages 30 and 33; ProVia January 28, 2026 warranty; Simpson February 2025 Nantucket data sheet; and Simpson warranty PDF, updated October 28, 2024. Coverage is conditional, with different provisions for components and occupancy.
The judgment row follows the documents' different scope. ProVia documents a paired configuration; Simpson's leaf data sheet leaves the assembled order to resolve. Neither thickness nor a longer term establishes a security ranking, whole-door energy rating, or installed-price advantage.
Decide which leaf opens every day
In ProVia's catalog, printed page 33, the buyer can specify either a left or right active door and inswing or outswing. The active leaf is the normal entrance; the catalog attaches the center astragal to the inactive door and describes top and bottom slide bolts for releasing it. Its unequal French-door option uses a larger everyday door beside a smaller inactive door.
Ask the seller to demonstrate the selected arrangement. Mark the active side and swing direction on an elevation viewed from a stated side of the house. Request the everyday passage dimensions and the larger passage when the inactive door is released. Have the supplier identify any hardware that remains in the opening in each position.
Check that arrangement against the actual entryway. Show the bidder furniture, interior trim, lighting, exterior steps, and any planned screen arrangement. Ask for the swing arcs on the drawing rather than relying on a showroom demonstration in an empty space. If equal and unequal pairs are both offered, request complete drawings and totals for each.
Include operating preferences before manufacture. Explain who will use the entrance and ask for a demonstration of reaching and releasing the inactive-door controls. Avoid accepting “both doors open” as the entire specification. The release sequence and ordinary walking passage deserve review while changes remain possible, particularly if the entrance serves as the required egress door.
The astragal is part of the quoted system
ProVia's pair-door drawing and notes, printed page 33, show the astragal securing the inactive door at the top and bottom. They describe a bolt entering the threshold and a sealing boot at that connection. These are specific facts about the illustrated ProVia system, rather than a promise about every double door.
Request the astragal model, finish, release arrangement, and replacement-part information in the pair-door hardware schedule. Ask whether it is supplied with the pair, installed by the dealer, or included in another hardware package. Have the supplier identify the contact surfaces and the prescribed adjustment procedure for the delivered system.
Inspect the meeting line at handover with both leaves closed. Ask the installer to demonstrate latching and then releasing the inactive leaf, and to identify the normal resting position of the controls. Record any rubbing, inconsistent contact, or unresolved operating concern for correction under the installation agreement. Do not accept a forced closing sequence as the agreed normal operation without an explanation from the supplier.
For a later repair, preserve the component identification. A quotation to change “weatherstrip” should identify whether it addresses the frame perimeter, meeting line, threshold connection, or another part. Ask for the diagnostic finding and proposed component before authorizing work. The manufacturer's assembly drawing makes that conversation more precise than a generic description of a drafty double door.
Multipoint locking requires an exact hardware name
ProVia's catalog, printed pages 33 and 116, lists Trilennium and PanoLock multipoint options for its French doors. The Trilennium page describes three full deadbolts and says that option is unavailable on steel L-frames. Do not treat every Legacy steel order as having the same frame or hardware compatibility.
Ask for the lock model, handleset, frame, preparation, and supplied keys on the order. Have the dealer show the actual closing and unlocking sequence. If a smart device is proposed, request written compatibility for that exact lock rather than assuming an electronic add-on replaces or controls every locking point.
The ProVia 2026 warranty gives Lifetime Finish Trilennium hardware mechanical coverage for 10 years, while its tarnishing provision follows the stated qualifying ownership conditions. The lock's mechanical term is therefore distinct from the basic-door term. Coastal installations have a separate finish limitation in the same document; ask the dealer to identify the applicable provision for the address.
Make service responsibility explicit. Request the party to contact for alignment, replacement hardware, and a failed lock component, along with its installation-work coverage. A manufacturer warranty document and a dealer's adjustment promise answer different questions. Keep both with the hardware schedule so a later claim can identify the supplied model and the responsible work.
Wood finishing needs an agreed completion scope
Simpson's Nantucket data sheet requires finishing on all six sides for warranty eligibility and lists wood-species choices. Its no-overhang feature comes with a reference to high-exposure finishing recommendations. Ask the dealer to attach the applicable finishing instructions for the selected species and exposure.
Have the quote distinguish factory preparation, dealer finishing, and site finishing. Identify who treats the edges and any surfaces exposed during fitting. Request the approved coating description and the completion record. A sample of the finished face is useful for appearance, but the signed finishing scope must also address surfaces you will not see when the door is closed.
The Simpson warranty PDF excludes installation and finishing of replacement doors or components from Simpson's responsibility. Ask the installer what separate commitment covers that work if a qualifying product claim results in a replacement. Keep ordinary maintenance instructions with the original order as well.
Request separate descriptions for the wood leaves, frame, astragal, threshold, and locks. Do not assume a leaf warranty extends to locally supplied frame components. If the dealer proposes a change of species, finish, or construction method, obtain revised coverage before accepting the substitution. The warranty should identify the product you actually buy rather than a family name used loosely in the proposal.
Required egress width: IRC R311.2 as adopted in Seattle
Seattle's city-hosted 2021 Residential Code, Chapter 3, R311.2, PDF page 50, states:
Not less than one egress door shall be provided for each dwelling unit.
The rest of R311.2 reads:
The egress door shall be side-hinged, and shall provide a clear width of not less than 32 inches (813 mm) where measured between the face of the door and the stop, with the door open 90 degrees (1.57 rad). The clear height of the door opening shall be not less than 78 inches (1981 mm) in height measured from the top of the threshold to the bottom of the stop. Other doors shall not be required to comply with these minimum dimensions. Egress doors shall be readily openable from inside the dwelling without the use of a key or special knowledge or effort.
These are quotations from Seattle's adopted IRC provision, not a national determination that a proposed pair complies. The minimum dimensions apply to the required egress door; the quoted text expressly exempts other doors from those dimensions. Ask the local authority which adopted edition, amendments, and replacement provisions govern your address.
For a pair, submit the assembly drawing and operating sequence. Ask the supplier to document the clear opening with the designated everyday leaf open, and to show what changes when the inactive leaf is released. Have the authority determine the acceptable arrangement. An overall frame width or a photograph with both leaves open does not answer the quoted measurement and operating questions.
Keep that determination with the order before approving manufacture. Ask for another configuration if the authority requires a different passage or release arrangement. The code quotation is a reason to request documented review; it is not permission to count nominal leaf widths as usable clear width or to infer compliance from the word “double.”
Warranty timing belongs on the installation schedule
The ProVia January 2026 warranty makes its basic-door provision conditional on finishing primed slabs within 90 days of installation with the specified exterior-grade paint or stain. Its basic-door transfer procedure calls for completion within 30 days of the ownership transfer. These are separate conditions, with separate triggering events.
Ask the dealer to identify whether your supplied pair is already finished and which primed components still need work. Have the installer record the installation date and finishing responsibility on the completion documents. If another company performs the coating work, request its schedule before agreeing to a handover that leaves finishing unresolved.
The Simpson warranty PDF identifies failure to seal all edges within 72 hours after fitting and hanging among its exclusions, and requires maintaining finish integrity. Its Nantucket term starts at shipment rather than installation. Ask the dealer to supply the relevant shipment record and finishing instructions with the wood-door order.
These documents use different start dates and finishing requirements. Request the applicable document for the exact supplied product and record the events it identifies. Keep purchase, shipment, installation, and finishing records together; a single invoice date may leave another required event undocumented. If ownership changes, provide the next owner with the product identification and the actual transfer provision instead of promising that every component keeps the original term.
Compare glass and finish as part of the complete pair
Request the glass description for each leaf, including any decorative pattern, divided-lite treatment, or privacy option. Have the dealer identify the warranty applicable to the actual glazing. If the two leaves differ in width or panel arrangement, ask to see the combined elevation before approving a pattern intended to align across the entrance.
View an actual finish sample and representative glass where possible. Ask for the manufacturer color or stain name on the order and identify how the frame and astragal will match. If you intend to repaint locally, obtain the applicable finishing instructions and coverage statement before selecting that route. Preserve the approved samples or identifiers with the product schedule.
Request performance documentation for the supplied assembly if energy or exposure ratings influence the purchase. Ask the seller to identify the tested configuration, glass, dimensions, and hardware. The construction table above describes leaves and warranty provisions; use the supplier's assembly evidence to answer a different question about the finished entrance.
When an option changes, request the revised complete installed total and schedule together. Keep the opening and restoration scope consistent so a decorative-glass comparison cannot silently become a different framing project. A signed change should make clear which product, finish, hardware, or work item changed and who accepts responsibility for the revision.
Get the installation and handover commitments in writing
Use the accepted elevation as the center of the agreement. Attach the assembled dimensions, active side, swing, frame, threshold, astragal, glass, lock, finish, and installation instructions. Have the contractor identify removal, opening preparation, wall connections, interior and exterior trim, disposal, and finish restoration. Request explicit exclusions next to the total.
Ask how concealed findings will be documented and priced. Distinguish a known framing alteration from a condition that can only be assessed after removal. Request a process for reviewing additional work before it proceeds, including who communicates the finding and how the revised completion scope will be recorded.
At handover, ask the installer to demonstrate ordinary entrance operation, every locking point, inactive-leaf release, and relatching. Match the delivered pair to the accepted schedule and note unresolved fit or finish items. Request the product identifiers, applicable warranties, care instructions, finishing records, and any required approval records.
Keep product coverage and installation coverage separately labeled. The ProVia 2026 warranty assigns installation labor for replacement products or parts to the purchaser. Ask what your installation company separately covers, including removal and restoration. That written answer is more useful for comparing bids than treating the word “lifetime” as a complete service commitment.
What we could not verify
- The ICC-hosted 2021 IRC Chapter 3 returned HTTP 403 on a plain fetch. A browser-user-agent retry exposed a subscription shell without the section text, and same-site alternatives did not yield usable section text. The code quotations use Seattle's reachable city-hosted adopted-code PDF instead.
