Windows — Replacement + Installation + Repairs

New windows, retrofit swaps, leak fixes, hardware repairs, and clean trim work — installed with correct flashing and air-sealing.

Most “bad windows” are actually bad details: missing flashing, broken seals, failed caulk, or poor air-sealing. We inspect the opening, confirm water-control layers (WRB/flashing/trim), then install or repair so it looks clean and performs better.

Window Services with wiBuilder

We provide replacement, new installs, and repairs. Our focus: correct the water/air details at the opening, then finish with clean trim.

Replacement + Installation

Retrofit swaps, full-frame replacements, and new openings (as scoped).

Install scope
Retrofit Install Swap into existing frame when conditions allow.
Full-Frame New frame + flashing when rot/leaks exist.
WRB + Flashing Sill pan, tape, and proper laps at openings.
Air-Seal Foam/backer rod/sealant as appropriate.
Trim Finish Exterior trim + interior returns as scoped.
Low-E Options Energy upgrades (product-dependent).
Noise Comfort Better seals help reduce sound intrusion.
Accurate Measure Sizing, reveal lines, and clean alignment.

What a “complete install” typically includes

  • Measure + confirm window type (retrofit vs full-frame)
  • Protect interior/exterior work area
  • Remove old unit (as scoped) and inspect opening
  • Repair minor rot/trim issues (if discovered, with approval)
  • Flashing/WRB integration at the opening (best practice)
  • Set, fasten, and air-seal the window
  • Exterior trim and interior touch-ups (as scoped)
  • Cleanup + operation check

Typical upgrades (optional)

  • Enhanced flashing package (high moisture-risk walls)
  • New exterior trim package / aesthetic refresh
  • Draft-sealing upgrades around other nearby openings

Note: Some projects require HOA/permit considerations depending on scope and local rules.

Repairs + Leak Fixes

Drafts, leaks, foggy glass, stuck windows, and trim rot — repaired at the source.

Repair scope
Leak Diagnostics Find water path: flashing/trim/sill issues.
Draft Sealing Weatherstripping + gap correction.
Hardware Repair Locks, balances, rollers, latches (as applicable).
Rot / Soft Trim Trim repair and localized substrate fixes.
Foggy Glass Broken seal symptom; coordinate glass/IGU swap.
Caulk Strategy Targeted sealing (not “seal everything”).
Operation Fix Windows that stick, scrape, or won’t lock.
Finish Touch-Ups Prime/paint on trim repairs as scoped.

Typical repair process

  1. Inspect and identify the cause (water path, seal failure, hardware)
  2. Open up only what’s needed to access the failure point
  3. Correct flashing/air-seal detail first (when relevant)
  4. Repair/replace trim, hardware, or glass components
  5. Verify operation + cleanup

Repair notes

  • Stains at the sill often mean flashing/drainage is the real issue.
  • Fog between panes usually indicates a failed insulated glass seal.
  • Drafts are commonly weatherstripping and air-seal problems.

Note: We confirm on-site. For leaks/rot, fixing the water path is priority before cosmetic finish.

Estimate Window Install or Repair Cost

Quick planning tool. Final pricing depends on window type/size, access (story height), trim condition, and whether flashing/rot repair is needed.

  • Replacement: uses typical per-window ranges.
  • Repair: uses typical service allowances.

Common Window Questions

Fast answers — we’ll confirm details during inspection.

Retrofit can work when the existing frame is sound and the leak details are good. Full-frame is often better when there’s rot, chronic leaks, or failed flashing/WRB details.

Often it’s a flashing or drainage-path issue. We focus on the water path first, then repair trim and finishes.

Usually a failed insulated glass seal. Often the fix is replacing the IGU (glass unit) rather than the entire window, depending on frame condition.

Often yes. Weatherstripping, air-sealing, and small hardware repairs can make a big difference if the frame and glass are still in decent shape.
