Division 08 — Openings.
Installation only.
We install doors, windows, and the hardware that goes with them. We don't sell or supply the materials — your client, your GC, or your supplier handles material. Our crew shows up, sets the opening, flashes, seals, hangs, hardware-sets, and cleans up.
Window Installation
Single-family and multi-family residential windows. New construction and retrofit. Single units to multi-hundred-unit packages.

Higher-spec multi-family and specialty residential scope where door and window install crosses into adjacent trades.

- Historic single-family remodel coordination with preservation review
- Punch-list / callback work on completed buildings
Manufacturers We Work With
Every opening runs the same sequence.
Single residential window or 200-unit multi-family retrofit — same five-step install. Documented because warranty claims hinge on it and callbacks are expensive.
Measure & demo
Verify field dimensions against shop drawings before any unit comes off the truck. Existing units come out without damage to the surrounding wall, trim, or interior finishes. Drop cloths and dust containment in occupied buildings.
Prep the opening
Clean residual caulk, sealant, and old insulation. Square and shim the rough opening. Install or replace flashing tape, sill pan, and moisture barrier per the manufacturer's published detail. Unsound openings get flagged before we proceed — not after.
Set the unit
Position, level, plumb, square. Shim at the manufacturer's specified contact points. Mechanically fasten through the nailing fin or jamb per the printed install instruction — not by feel.
Insulate & seal
Low-expansion foam at the perimeter. Backer rod and sealant at the exterior face. Interior air-seal where the spec or energy program (Energy Star, blower-door test) requires it.
Finish & walk
Reinstall trim. Verify operation of every sash, lock, hinge, and weatherstrip. Glass cleaned, floors vacuumed, debris hauled off-site. Walk every opening with the super before we leave.
What we don't do.
We don't sell or supply materials. If you need someone who can also bring you the units, you want a window company — we'll gladly install whatever you spec.
We don't do commercial storefront, custom glazing, or fabrication. We're a residential installer — single-family and multi-family openings, not commercial curtain wall.
We don't take direct-to-homeowner residential remodel work. All residential installs come through general contractors and residential remodelers we sub for.
