Windows Estimating Services for Residential, Commercial & Multifamily Projects
Accurate window, frame, sash, and glazing takeoffs covering aluminum, vinyl, wood, and steel windows delivered in 24 to 48 hours.
Professional Windows Estimating for Contractors, Distributors and Builders
Windows are one of the most critical building envelope components on any project. Every window unit, frame, sash, glazing panel, and piece of hardware carries material cost, thermal performance requirements, and code compliance obligations. An incomplete window takeoff or missed glazing specification can expose a contractor to change orders, energy code violations, and project delays before the first unit is installed.
The Virtual Estimation provides professional windows estimating services for window manufacturers, replacement window contractors, general contractors, commercial builders, and multifamily developers across all 50 US states. Our estimators count every window unit, frame, sash, glazing panel, and accessory from the architectural drawings and deliver a complete bid-ready estimate within 24 to 48 hours.
We use PlanSwift and Bluebeam Revu for digital takeoffs, RSMeans for regional pricing by zip code, and manufacturer catalog data for window, frame, and glazing pricing specific to brand, series, and performance rating. All estimates are delivered in Excel organized by specification section ready for bid submission.
Window Systems We Estimate
Our estimating team covers every window scope specified in residential, commercial, and multifamily construction. Whether your project requires impact-rated hurricane windows for a Florida condominium or custom wood windows for a luxury residence, we produce accurate quantities for every component of the specified window package.
Who We Serve
- General Contractors: GCs use our window estimates to evaluate subcontractor bids and carry accurate allowances for window, frame, and glazing installation scopes on commercial and residential projects.
- Window Manufacturers: Manufacturers use our estimates to prepare material orders for window frame extrusions, sash components, glazing, and hardware packages based on production schedules.
- Specialty Window Contractors: Specialty contractors use our takeoffs to price installation labor independently of material supply for complete window scopes including custom and specialty glazing systems.
- Commercial Builders: Commercial builders use our window takeoffs to price storefront systems, curtain wall assemblies, and impact-rated windows for office, retail, and institutional projects.
- Multifamily Developers: Multifamily developers use our estimates to budget window packages for unit windows, corridor glazing, and common area storefront systems across residential and hospitality projects.
- Replacement Window Contractors: Replacement contractors use our takeoffs to estimate full-frame and insert replacement window projects including trim, flashing, and insulation material quantities.
What Our Window Takeoff Covers
A complete window takeoff counts every window unit, frame, sash, glazing panel, and accessory shown on the window schedule and architectural drawings. Estimators who count only the window units and omit frames, hardware, flashing, trim, and glazing consistently underbid window scopes by 15 to 25 percent. Our takeoffs are complete by design.
