CountBricks: How Much to Replace Window Trim Cost Guide

Head of Sales

Introduction: Why Knowing Window Trim Costs Matters

Homeowners constantly ask our project managers one question: how much to replace window trim? Trim may be a small component, but it frames your view, seals out drafts, and finishes the look of every room. If you underestimate this line item, your budget and schedule can unravel quickly. That is why CountBricks developed real-time voice-driven estimating software that calculates labor, material, and overhead in seconds—so you never guess, you know.

The Core Factors That Drive Replacement Price

• Linear footage of existing trim to be removed and new trim to be installed

• Material selection—MDF, finger-joint pine, hardwood, PVC, composite

• Profile complexity—flat stock, colonial, craftsman, custom milled

• Interior vs. exterior elevation exposure to weather

• Condition of surrounding casements and drywall

• Access challenges—upper floors, tight corners, historical homes

• Labor rate fluctuations in your ZIP code

• Disposal fees and building department requirements

Cost Range You Can Expect in Greater Los Angeles

CountBricks maintains a continuously updated cost library sourced from local suppliers and subcontractor bids. Across thousands of residential projects, we see an installed price range of $7–$15 per linear foot for standard interior MDF trim, and $18–$28 per linear foot for exterior PVC or hardwood profiles. A typical three-bedroom home with 240 linear feet of window trim will land between $1,700 and $6,700 depending on the variables above.

Material Breakdown

• Primed MDF: $1.25–$2.10 per linear foot

• Finger-joint pine: $1.80–$3.40 per linear foot

• Clear poplar or oak: $3.90–$6.50 per linear foot

• Cellular PVC or composite: $4.10–$7.00 per linear foot

Labor & Equipment

• Removal and prep: $0.80–$1.20 per linear foot

• Installation: $2.50–$4.75 per linear foot

• Finish carpentry detailing & paint: $1.20–$2.75 per linear foot

Because CountBricks captures jobsite dimensions via voice commands and imports them directly into our cloud database, we eliminate redundant data entry and pass those labor savings to our clients.

DIY or Hire a Pro?

• DIY makes sense for one or two windows if you already own a miter saw and nail gun

• CountBricks can dispatch pre-vetted finish carpenters, backed by our workmanship warranty and digital punch-list tracking

Real-World Case Study: Silver Lake Bungalow

A 1920s bungalow in Silver Lake required 180 linear feet of rotted exterior window trim replacement. CountBricks recorded measurements in 12 minutes, selected PVC colonial casing, and produced an AI estimate of $4,200. The homeowner accepted via e-signature the same afternoon. Material arrived two days later, installation finished in one day, and final cost matched the estimate within 1.5 %. Explore similar wins at CountBricks.com/portfolio.

Beyond the Basics: Three Ways CountBricks Elevates Trim Projects

1. Integrated Blueprint Takeoffs
CountBricks AI reads PDFs and DWG files, highlights every window opening, and calculates trim quantities automatically. This eliminates manual counting errors and speeds up bid turnaround by up to 65 %.

2. Dynamic Supplier Sync
Our platform syncs with regional lumber yards twice daily. When poplar prices drop, your estimate reflects the savings instantly. When PVC stock tightens, the system suggests alternate profiles to maintain budgets without sacrificing durability.

3. Post-Installation Analytics
Most contractors move on after punch-out, but CountBricks tracks actual labor hours against estimates. • If crews outperform the budget, you’ll see real-time profit upticks • If productivity slips, our dashboard flags the variance so future bids stay razor-sharp.

Pro Tips for Flawless Finish Carpentry

• Store trim flat and acclimate it 48 hours before install to prevent warping

• Use back-band molding on wide jambs to hide drywall irregularities and avoid costly shimming

• Prime cut edges, especially on MDF, to lock out moisture and reduce callbacks

• Pair 18-gauge brad nails with construction adhesive for tight joints that resist seasonal movement
