Division 08 Openings Takeoffs That Keep Your Bids on Budget
Division 08 looks manageable on paper. Then you open the door schedule on a mid-size commercial job and suddenly you're staring down 120 opening types, three hardware groups, fire ratings on half of them, and a curtain wall system the architect specified two weeks before the bid deadline. Every component has to be counted correctly, specified right, and priced to current market rates. Miss a frame gauge or overlook a hardware set and you're dealing with change orders and budget overruns that cut straight into your margins.
Here's something most contractors don't realize until it's too late: openings typically represent 8 to 12 percent of total project cost, yet they're responsible for nearly half of all change orders on commercial builds. That gap between what was estimated and what was actually needed is almost always a takeoff problem: wrong quantities, missed specs, or outdated pricing. Getting the openings estimate right isn't just good practice. It's a core part of your bidding strategy.
PRO Estimating Services has been delivering accurate, bid-ready Division 08 estimates since 2011. Our professional estimators use PlanSwift, Bluebeam, and RS Means pricing data to produce precise takeoffs on every opening in your project, from standard interior wood doors in single family homes to complex curtain walls and thermal and glazed openings on large commercial and industrial projects.
Flat-fee pricing. No surprises. Turnaround in 24 to 48 hours.

● Full Division 08 Coverage
What's Included in Our Openings Estimating
CSI Division 08 covers a lot of ground. Here's what our opening estimating covers across every project type.
Doors and Door Frames
Metal, hollow metal, wood doors, plastic, and composite doors. We count every leaf, size every frame, note handing and swing direction, and flag fire rated doors with the correct assembly specs. Nothing gets missed: not the hardware preps, not the jamb depths, not the rough opening sizes.
Windows and Window Frames
Single and double-hung, casement, fixed, sliding, and specialty window units. We measure unit sizes, specify frame materials (aluminum, bronze, vinyl, fiberglass) and calculate quantities directly from your architectural drawings. Window frames are noted by type and matched to your specs.
Curtain Walls and Storefront Glazing
Curtain walls require their own level of detail. Mullion counts, glazing thickness, frame profiles, and anchorage points all get quantified separately. Our estimators handle both stick-built and unitized systems, along with storefront entrances and glazed openings.
Skylights and Roof Windows
Unit skylights, metal-framed and plastic-framed skylights, glazed canopies, and translucent assemblies. We pull quantities from roof plans and coordinate against your structural and architectural drawings.
Hardware and Door Accessories
Complete hardware schedules: hinges, closers, locksets, exit devices, access control preps, and finish hardware. Hardware is where a lot of estimates fall apart, especially on commercial jobs where keying systems and access requirements vary room by room.
Louvers and Vents
Fixed and adjustable louvers, louvered equipment enclosures, and vent openings. Quantities and opening sizes are pulled from mechanical and architectural plans so your procurement schedule aligns with installation sequencing.
Acoustic Doors and Specialty Openings
Fire rated doors, acoustic doors, blast-resistant assemblies, and other specialty units. We cross-reference door schedules against building codes and specification sheets so every assembly is verified before quantities are locked.
Access Panels and Other Openings
Pass-through windows, access panels, and integrated door opening assemblies are captured in the takeoff just like everything else. If it has a schedule reference or appears on the floor plans, it goes into the count.
● Common Estimating Failures
Why Opening Estimates Go Wrong (And How We Fix That)
This division causes more change orders than almost any other trade. There's a reason for that.
Every opening is technically its own assembly. The door leaf, the frame, the hardware set, the glazing, these are interdependent components that have to match each other and comply with building codes at the same time. Miss one item in a hardware schedule and the whole opening fails inspection. Order the wrong frame gauge and you're back-ordering on a job that was supposed to close out next week.
Most estimating mistakes come down to four recurring problems:
Human Error on Door Schedules
Plans with 80 or more door types are common on commercial projects. Counting manually without dedicated estimating software is exactly where costly mistakes happen. Our estimators use industry-leading tools and a double-check process that catches discrepancies before the bid goes out.
Outdated Material Pricing
Costs for aluminum, specialty glass, and fire-rated assemblies shift regularly. Running last year's RS Means data against this year's bid is a real risk, especially with the price volatility the market has seen. We price to current rates every time.
Missing Code Requirements
Fire ratings, egress compliance, ADA hardware specs, these aren't optional and they add real cost. Our estimates account for applicable building codes from the start, so nothing surfaces as an unexpected expense during construction.
Underestimated Labor Hours
Installing curtain walls, fire-rated assemblies, and acoustic doors takes more time than standard units. We calculate labor costs based on the actual opening type and site conditions, not blanket averages that tend to leave money on the table.
Contractors across the country trust us with their numbers. Over 8,300+ projects in, we know what a tight, defensible openings estimate looks like, and exactly how much it costs when the numbers are wrong.

Who We Work With
Our openings estimating services cover a broad range of clients, but most fall into one of these categories.
General Contractors
Need a complete Division 08 breakdown as part of a full project estimate, or want the openings scope priced as a standalone trade package. Office buildings, schools, hospitals, retail developments. We handle all of it.
Door & Window Subcontractors
Bidding jobs where the door schedule runs long and manual takeoffs eat hours they don't have. Tighter numbers mean more competitive bids, and more competitive bids mean more work.
Specialty Glazing Contractors
Working on storefront systems, curtain walls, and large glazed assemblies on commercial and industrial facilities.
Developers and Architects
Need a realistic budget during design, before construction documents are finalized, to confirm feasibility or evaluate value engineering options.
Hardware Distributors & Suppliers
Need quantity data early enough to plan procurement, coordinate long lead items, and support their contractor clients.

Projects We Estimate
Openings show up in every type of construction. We've handled Division 08 estimates across all of them.
Residential Projects
Single family homes, custom builds, townhomes, multi-family housing. Door and window counts, frame specs, and hardware schedules for residential projects typically come back in 24 hours or less.
Commercial Buildings
Office buildings, retail spaces, hotels, restaurants, schools, and healthcare facilities. These projects carry larger door schedules, storefront systems, and often full curtain wall assemblies.
Industrial Facilities
Warehouses, manufacturing plants, and distribution centers. Industrial openings frequently include heavy-duty hollow metal frames, specialty acoustic doors, and louvered equipment enclosures.
Renovation & Retrofit Projects
Matching existing conditions adds complexity. We factor in as-built constraints, existing frame conditions, and replacement specs to make sure the estimate reflects what the job actually involves.
A 14-door remodel or a 500-opening hospital build. The level of care we put into the takeoff doesn't change.
● Pricing Factors
What Drives the Cost of Your Openings Scope
Before you can build a solid bid, you need to understand what actually moves the price needle on Division 08 work. These are the factors our estimators account for on every job.
Material Type and Specification
Standard hollow metal doors and painted steel frames are relatively straightforward to price. Architectural wood doors, specialty glass, thermally broken aluminum frames, and high-end hardware packages cost more, sometimes significantly. We price to your actual specifications, not catalog averages.
Opening Count and Variety
A project with 20 standard doors is a different animal from one with 180 openings across 40 types. More volume means more material, more labor hours, more hardware sets to coordinate, and more room for errors if the takeoff isn't thorough. Precise calculations from your design documents are the only way to get the number right.
Fire Ratings and Code Compliance
Fire rated assemblies, smoke ratings, and egress hardware carry cost premiums that add up fast on commercial and institutional projects. Building code requirements vary by occupancy type and jurisdiction. We cross-reference specs against applicable codes from the start, so there are no surprises buried in the budget.
Site and Installation Conditions
Ground-floor installation in a new commercial building is a different job than retrofitting frames in an occupied hospital, or coordinating deliveries to a high-rise with restricted freight access. Labor hours get priced to what the site actually requires.
Long Lead-Time Items
Curtain wall systems, specialty glazing, and architectural hardware often carry lead times of 8 to 16 weeks or more. We flag these items in the estimate so procurement can move early and your schedule stays intact.
Knowing what's driving cost before the bid goes out is how you protect your profit margins and avoid surprises mid-project.

● Common Questions
Frequently Asked Questions
What does openings estimating include?+
Opening estimating covers all components under CSI Division 08: doors, door frames, windows, window frames, curtain walls, glazed openings, skylights, hardware, louvers, acoustic doors, fire rated doors, and specialty assemblies. We calculate material quantities, installation costs, and labor costs for every opening shown on your plans and in your door and window schedules.
How long does the estimation process take?+
Most openings estimates are delivered within 24 to 48 hours. Residential projects with standard door and window schedules are usually ready sooner. Large commercial jobs with complex curtain wall systems or extensive hardware schedules may take a bit longer. We'll confirm your turnaround during the initial consultation.
What file formats do you accept?+
We work with PDF plans, CAD drawings, Bluebeam files, and most standard architectural plan formats. If you have a separate door schedule or window schedule, include it. The more complete your submission, the faster and more accurate your estimate.
Do you handle both commercial openings estimating and residential projects?+
Both. We estimate doors and windows for single family homes, multi-family housing, office buildings, retail spaces, healthcare facilities, warehouses, and industrial facilities. The scope changes, but the methodology is the same: detailed takeoffs built directly from your submitted plans.
What's the difference between a takeoff and a full estimate?+
A takeoff gives you quantities, specifically counts of doors, windows, frames, and hardware items. A full estimate adds current market pricing for materials and labor, giving you a complete cost breakdown by line item. Most clients request the full estimate package for bidding purposes, though we offer both.
Why outsource openings estimating instead of doing it in-house?+
Honestly, Division 08 is time-consuming. A mid-size commercial project can have 150 different opening types with unique hardware sets, fire ratings, and accessibility requirements on each one. Doing detailed takeoffs in-house pulls your estimators away from project management and field coordination. We handle the estimation process so your team can focus on winning jobs and running them.
Do you provide estimates for curtain walls specifically?+
Yes. We handle stick-built and unitized curtain wall systems, quantify mullion counts, glazing area, frame profiles, and anchor locations. Curtain wall estimates are delivered on the same flat-fee structure, within the standard turnaround window we apply to all openings work.
How is your pricing structured?+
Flat-fee, based on project scope. Pricing ranges from $200 to $5,000. You receive a fixed quote before anything starts. The invoice matches what we quoted. Simple as that.
