Window Replacement
Residential window replacement for Bergen County homes. Full-frame and insert install, vinyl through fiberglass products, factory finishes, and proper flashing — managed by a registered NJ contractor.
Window Replacement & Install
Window replacement falls into two categories with different cost and scope: full-frame replacement (tear-out down to the rough opening, replace flashing, repair sheathing if needed) and insert replacement (existing window frame stays, new sash and frame slide into the pocket). Full-frame is more durable and addresses any hidden water damage; inserts are faster and lower cost when existing frames are sound. Product choice (vinyl through fiberglass) determines long-term performance.
- On-site measurement and product specification per opening
- Full-frame replacement — tear-out, flashing, sheathing repair, new install
- Insert/pocket replacement when existing frames are structurally sound
- Vinyl, wood-clad, composite, and fiberglass product options
- Energy Star rated U-factor and SHGC ratings per opening orientation
- Manufacturer-approved flashing tape and integration with weather barrier
- Interior trim — casing, sills, and apron — preserved or replaced per scope
- Exterior trim wrap with aluminum coil-stock or PVC
- Old window removal and disposal
Bergen Restoration installs residential replacement windows from major manufacturers. Historic, custom-shape, and high-performance commercial windows may require specialty manufacturer relationships and longer lead times.

Window Replacement Guides
Decisions that determine whether the windows perform and last.
Insert vs Full-Frame Replacement
- Insert replacement: new sash-and-frame unit inside the existing frame — faster, cheaper, trim untouched; only right when the old frame is square and rot-free.
- Full-frame: everything comes out to the rough opening: new flashing, insulation, sill — the fix for rot, racked frames, and failed installs.
- Glass-loss caveat: inserts shrink visible glass an inch or so per side; on small windows that reads noticeably.
- Inspection decides: probing sills and checking square tells which method your openings actually support — not preference, condition.
- Mixing is normal: sound openings get inserts, compromised ones get full-frame — on the same house, in the same project.

Glass Packages for This Climate
- Low-E coatings: microscopic metal layers reflect heat back into the room in winter and reject solar gain in summer.
- U-factor: the insulation number — 0.30 or lower for a meaningful comfort and energy step over old double-pane.
- Argon fill: inert gas between panes slows conductive loss; standard on quality units, worth confirming on budget ones.
- Double vs triple: double-pane low-E serves most homes here; triple earns its premium on large north exposures and street-noise fronts.
- Warm-edge spacers: the pane separator drives edge condensation — the detail that decides whether winter mornings show fog rings.

Why the Install Outranks the Window
- Sill pan: the sloped waterproof layer under the unit that drains incidental water out, not into the framing.
- Flashing sequence: head and side flashing lap into the weather barrier shingle-style; done backwards, walls collect water invisibly.
- Shim & square: a unit shimmed square and plumb operates smoothly for decades; a racked one binds within seasons.
- Foam, not stuffed: low-expansion foam seals the perimeter gap without bowing jambs — fiberglass stuffing leaks air by design.
- Interior air seal: the inside bead completes the air barrier; skipping it is why new windows can still feel drafty.

Vinyl, Wood-Clad or Fiberglass
- Vinyl: the value standard: welded, low-maintenance, honest thermal numbers; color and hardware options thinner at the bottom of the line.
- Wood-clad: wood interiors under aluminum or fiberglass exteriors — the premium look for stained trim and period homes, at a premium price.
- Fiberglass: paintable, dimensionally stable through temperature swings, near-wood sightlines with zero-maintenance skin.
- Composite lines: newer engineered frames split the difference; judge them by U-factor, sightlines, and warranty terms, not marketing tier.
- Match the house: a 1920s colonial with stained casings and a 1985 split-level do not want the same window — and resale notices.

Replacing the House in Stages
- Phase by elevation: complete faces of the house — front first, weather side second — so no elevation shows mixed windows.
- Worst first: failed seals, rot, and non-openers jump the queue regardless of which wall they sit on.
- Lock the spec: same line, series, color, and grid pattern across phases; product lines drift, so record the exact order codes.
- Two phases, not five: mobilization has a floor cost; larger phases buy better per-window pricing.
- Weather independence: window swaps run one opening at a time in nearly any season — winter phasing is fine.

Cost & Timeline Guide
- Insert replacement: vinyl inserts run $700–$1,400 per window in 2026 ranges.
- Full-frame vinyl: $1,000–$2,000 per opening including flashing and trim rework.
- Premium frames: wood-clad full-frame $1,800–$3,000+; fiberglass $2,500–$3,500+ per window.
- Specialty shapes: large picture windows, custom geometry, and premium exterior trim wrap add to those ranges.
- Timeline: crews typically set 8–12 inserts a day; a whole-house replacement usually finishes in 1–3 days with each opening closed the same day it opens.

Your Window Replacement Process
Inspect & diagnose
Evaluate crack width, pattern, location, and whether water is present or seeping. Determine whether the crack is structural, cosmetic, or moisture-driven.
Select repair method
Recommend epoxy, polyurethane, carbon fiber reinforcement, or engineering coordination based on findings. We explain the options before anything is scheduled.
Prep & seal
Clean the crack, install injection ports where applicable, inject sealant, and apply surface seal. Carbon fiber straps installed where lateral pressure is a concern.
Waterproof & coordinate drainage
Apply waterproofing membrane over repaired sections. If water pressure from drainage is the root cause, coordinate French drain, sump pump, or yard drainage work.
Frequently Asked Questions
Standard insert replacement runs 1–2 hours per opening for an experienced crew. Full-frame replacement runs 3–5 hours per opening including flashing, trim, and cleanup. Most full-house projects (8–15 windows) complete in 2–5 working days.
Most Bergen County municipalities do not require a permit for like-for-like residential window replacement. Permits may be required if window sizes change, if the opening is structurally modified, or if egress code applies (bedroom or basement windows). We confirm with your town before scheduling.
Vinyl insert replacement runs $700–$1,400 per window in 2026 ranges. Full-frame vinyl $1,000–$2,000. Wood-clad full-frame $1,800–$3,000+. Fiberglass full-frame $2,500–$3,500+. Large picture windows, custom shapes, and premium trim wrap add to those ranges.
We install from major manufacturers including Andersen, Marvin, Pella, Harvey, and equivalents. Specific product line within each (e.g., Andersen 200/400/Renewal) is selected per project based on budget, performance needs, and exterior style.

Inserts nest into sound existing frames — faster and cheaper; full-frame strips to the opening and resets flashing — right when frames rot or sizes change. The frame condition audit decides, window by window.
Double-pane low-E with argon covers Bergen County's swings; triple-pane earns its premium on exposed elevations and bedrooms near noise. Numbers to compare: U-factor and SHGC, not brand slogans.
Wind-driven nor'easter rain tests every opening's integration with the housewrap — sill pans and taped flanges keep walls dry for decades. A mediocre window flashed perfectly beats the reverse.
By exposure is the smart phasing: the weather-beaten side first, matching sightlines and grids so phases read as one decision. Full-house at once wins labor efficiency when budget allows.
Insert installs preserve interior casings; full-frame renews exterior trim and lets interiors upgrade. Trim expectations get set per window in the scope, not discovered on install day.
Fake muntins in wrong patterns date instantly; matching the house's era — colonial grids on colonials, clean lite on moderns — keeps the facade coherent. Black interiors are a commitment; we'll show samples in your rooms.
