Homeowner planning
New siding is the right time to replace drafty windows and seal every opening once.
Walls are open during siding tear-off, so flashing, capping, and insulated glass can be sequenced correctly. NJ Vinyl Siding bundles windows with siding across Bergen, Essex, Union, Morris, and Passaic counties.

Why bundle windows with siding replacement
Siding tear-off exposes rotted sheathing, failed head flashing, and gaps around every frame. Replacing panels without fixing those openings leaves the same drafts behind new vinyl.
NJ Vinyl Siding scopes windows while walls are open so aluminum capping, housewrap overlap, and insulated glass land in the right order. One crew, one calendar, one written price.
- Rotted trim and sheathing show up when old siding comes off
- Frame gaps are easier to flash before new panels go on
- Custom aluminum capping matches siding color at every opening
- One mobilization saves versus hiring a window company after siding is done
- Street-facing curb appeal jumps when siding and windows refresh together
Install sequence: windows before siding, flashing first
Windows go in before field panels so sill pan flashing, head tape, and capping profile are set before siding locks at the jambs. NJ Vinyl Siding documents each opening with photos before and after.
On Bergen County colonials and split-levels, crews typically complete window replacement across the house, then hang housewrap and siding with continuous flashing at every head and sill.
- Remove old sashes and frames, inspect sheathing at each opening
- Install sill pan flashing and head tape before window set
- Fabricate aluminum capping on-site to match siding profile
- Run housewrap over head flashing, then hang siding courses
- Seal interior and exterior caulk to manufacturer spec
Energy savings from insulated siding plus new windows
Old single-pane or failed double-pane units leak heat all winter. Pairing new Low-E insulated glass with foam-backed vinyl siding cuts thermal bridging along stud lines on North Jersey walls.
Homeowners in Teaneck, Wayne, and Ridgewood often report quieter rooms and lower heating bills the first season when both trades complete together. Triple-pane upgrades on street-facing bedrooms add the most comfort gain.
- Double-pane Low-E with argon fill is standard on NJ replacements
- Triple-pane adds +$500–$900 per window on west- and street-facing rooms
- Insulated vinyl siding reduces heat loss through wall cavities
- Combined envelope upgrades can deliver 20–35% energy savings
- See insulated vinyl siding guide for panel options
North Jersey homes where the combo makes sense
Bergen County capes and colonials built in the 1950s through 1980s often still carry original aluminum windows and builder-grade siding. Both are past useful life at the same time.
Fort Lee high-rises and split-levels along Route 46 need tight flashing at every floor line. NJ Vinyl Siding coordinates capping color with panel choice so Ridgewood and Paramus street views look intentional, not patched.
- Hackensack, Teaneck, Fort Lee: dense lots, one-season exterior refresh
- Ridgewood, Wayne, Montclair: resale markets reward matched trim and glass
- Millburn, Summit, Chatham: insulated siding plus triple-pane on primary suites
- No trip fee across Bergen, Passaic, Essex, Union, and Morris counties
- Free on-site estimate with line items for siding and windows separately
Typical pricing when you bundle siding and windows
Window-only and siding-only bids hide overlap at the jambs. NJ Vinyl Siding quotes combo scopes with line items so you see each trade and shared flashing labor.
For a typical North Jersey colonial, 10–15 double-pane replacements run $4,500–$9,000 with aluminum capping. Full-home window replacement with capping at every opening runs $7,000–$14,000. Windows plus siding on one written contract often lands at $18,000–$35,000+ depending on material tier and opening count.
- 10–15 double-pane windows: $4,500–$9,000 with capping
- Triple-pane upgrade: +$500–$900 per window
- Full-home windows with capping: $7,000–$14,000
- Windows + siding combo: $18,000–$35,000+ on one contract

Siding and windows FAQ
Replace windows when frames are drafty, glass is fogged, or flashing at the opening failed. New siding over old leaky units wastes the tear-off. NJ Vinyl Siding inspects every opening during siding demo and recommends replacement or rewrap in writing.
