Doors, Windows & Openings Estimating Services
Missed items on an opening estimate don't show up until you're three weeks into the job. By then, you've got a budget overrun, an awkward conversation with the GC, and profit margins that've disappeared. We prevent that. Send us your plans and get accurate opening takeoffs back in 24 to 48 hours, priced for your market, ready to bid from.
The One Thing That Kills Opening Bids
Missed items. That's usually it. A contractor sends in a bid on a commercial office project, wins it, and three weeks into the job realizes the door and window schedule had 14 specialty openings that weren't in the estimate. Budget overrun, a conversation with the GC nobody wants to have, profit margins gone. We've seen this story more times than we can count. It's frustrating, it's avoidable, and it's exactly what our openings estimating services are built to prevent.
At Blaze Estimating, our certified estimators within our construction estimating services pull up your architectural drawings and work through the full opening scope. Doors, frames, windows, curtain walls, glazed openings, hardware, specialty systems. Nothing gets grouped into a catch-all quantity. What you get back is a detailed estimate you can actually build your bid on, not a rough number you have to second-guess before submitting.
And here's the thing most contractors learn the hard way: openings estimating isn't just counting doors and windows. Miss the hardware package on a 40-door commercial job. Forget to account for fire rated assemblies on a healthcare project. Overlook the curtain wall section because it wasn't called out clearly in the architectural drawings. Any one of those gaps creates cost overruns, change orders, and schedule problems that follow you for the rest of the job.
Residential, commercial, industrial, retail spaces. We handle the full United States scope and we've done it across 7,900+ projects. Send us your plans. Let's get your numbers right the first time.
What We Cover in Our Openings Takeoff Services
Let's be clear about what opening estimating actually covers. A lot of contractors assume it's just doors and windows. It's not. Here's the full scope.
Doors and Frames
Doors and frames covers a lot of ground. Hollow metal doors and frames, wood doors, fire rated doors, acoustic doors, blast-resistant and security assemblies. Aluminum, bronze, vinyl, fiberglass, access doors, specialty types. We price the frame, the hardware, weatherstripping, thresholds, all of it together. Whether it's a standard 3/0 wood door on a residential job or a UL-listed fire assembly on a hospital project, we've done it.
Windows and Glazing
Aluminum, vinyl, insulated glass units, energy-efficient glazing systems, tempered and laminated glass, specialty glazing. The window scope on most projects is longer than people expect. We pull frame material types, thermal break requirements, and glazing specs straight from your design documents. Window frames matter more than most contractors account for. On commercial and residential projects especially, energy code compliance ties into the whole assembly cost and getting the spec wrong changes your number.
Curtain Wall Systems
This is where in-house estimating tends to fall apart, and honestly, that's fair. Structural glazing, pressure wall assemblies, rainscreen systems, thermal break assemblies. Curtain walls require a level of detail that general estimating tools don't handle well. Our professional estimators are experienced with thermal and glazed openings. We work through these systems methodically. Brackets, mullions, glass units, sealants, all of it priced separately so nothing gets absorbed into a lump sum that unravels later.
Storefronts and Entrance Systems
Aluminum storefronts, all-glass entrances, sliding doors, automatic door systems, revolving doors. We include the full assembly and account for hardware, sealants, and glazing specs. Retail spaces especially have unique requirements here. High-traffic entrances need different hardware specs than a standard commercial office entry, and that difference shows up in the material costs and installation costs.
Specialty and Industrial Openings
Overhead doors, roll-up doors, coiling doors, hangar doors, loading dock equipment, security gates, smoke containment systems, louvers, grilles, and vents. Industrial openings are a specific category. The materials are heavier, the hardware is more specialized, and the building codes for industrial facilities add another layer. We handle the labor hours and material costs for all of it.
Hardware and Accessories
Hinges, locks, closers, panic hardware, ADA devices, thresholds, weatherstripping, sealants, and glazing accessories. Hardware can add 15 to 25 percent to your total opening costs on commercial projects. We don't estimate doors without the hardware. And we don't group it into a catch-all line that falls apart when your supplier quotes it back.
96% Estimate Accuracy Guaranteed
Our 96% Accuracy Guaranteed is tracked against actual project costs, verified by contractors who've used our opening estimates and followed what jobs actually came in at. Every estimator on the team treats that number as a personal standard. You're not getting generic pricing applied to a rough takeoff. You're getting opening estimates built from your actual drawings, priced for your specific market, with every line item reviewed before delivery.
Construction Types We Cover in Opening Estimating
Commercial, healthcare, industrial, residential, high-security. Every project type has different opening requirements and code considerations. We know the difference.
Commercial Buildings
Office buildings, retail spaces, shopping centers, mixed-use developments, hotels. Commercial is a significant part of what we do and it runs medium to high complexity on most projects. You're dealing with curtain wall systems, storefronts, entrance systems, security doors, fire rated assemblies all on the same bid. Code requirements around fire ratings, ADA compliance, energy performance, and security all affect your cost analysis in ways that aren't always obvious in the drawings. We know where to look and what to flag before it becomes a problem.
Get Commercial Opening EstimateHealthcare Facilities
Hospitals, medical centers, surgical centers, specialty clinics. Very high complexity. Fire rated doors, lead-lined doors, clean room doors, security doors, and specialized hardware throughout. Healthcare projects have tight specs and zero tolerance for substitutions. Our thorough cost analysis accounts for UL listings, lead equivalencies, and code-compliant hardware packages. This isn't work you want to rush or estimate loosely.
Get Healthcare Opening EstimateEducational Buildings
Schools, universities, training facilities. Classroom doors, security entrances, emergency exit hardware, window systems. These projects typically run medium complexity, but they have specific security requirements that affect opening requirements and costs. Building codes for educational occupancies add considerations around fire egress, ADA access, and forced-entry resistance that a general estimating approach tends to miss.
Get Educational Opening EstimateIndustrial Facilities
Manufacturing plants, warehouses, distribution centers, processing facilities. Industrial openings are their own category. Overhead doors, roll-up doors, security gates, fire doors. Materials and labor hours differ significantly from commercial work, and the performance requirements, clearance heights, operational weight ratings, thermal specs, are different too. We've done enough industrial projects to understand what that scope actually costs.
Get Industrial Opening EstimateResidential Projects
Single-family homes, apartment buildings, condominiums, townhomes. Entry doors, interior doors, patio doors, windows. Residential is more straightforward but it still needs accurate quantities. Material shortages on residential jobs are a headache, especially when you're mid-installation and the replacement lead time is three weeks. You get precise takeoffs that give you the right material order the first time, not a guess with some buffer added.
Get Residential Opening EstimateHigh-Security Facilities
Government buildings, data centers, correctional facilities, secure facilities. Blast-resistant doors, bullet-resistant glazing, access control systems, specialized frames. These projects require specific knowledge of government security standards and certified manufacturer specs. Not every estimating company handles high-security openings well. We do, and we're upfront about what each assembly requires from a specification and certification standpoint.

Who Sends Us Opening Plans
Most of the people who send us plans are general contractors who need openings scoped cleanly before their overall bid goes out. Door and window subcontractors make up a big chunk too, mostly needing detailed takeoffs for fabrication and installation quotes. But we also work with developers who want a cost analysis before committing to a design, architects who need budget numbers during design development, and construction managers juggling multiple trades under a tight schedule. Pretty much anyone who needs to know what an openings scope costs before they commit to a number.
Basically, if you're working a construction project that has openings in it, we're your reliable partner for the estimating side. Our professional estimators have worked across all project types and sizes, from a single-family home with six exterior doors to a high-rise commercial building with full curtain wall systems and hundreds of fire rated assemblies. The scope doesn't change how carefully we work through it.
The contractors who consistently win competitive bids aren't always the cheapest. They're usually the most accurate. Subs who submit tight, detailed estimates are the ones GCs call first when a new project comes in. That's the real return on getting your opening estimates right.
How Our Opening Estimating Process Works
Five steps. Pretty straightforward. This is what happens from the moment your plans land with us.
Initial Consultation and Plan Review
Send us your architectural drawings, door and window schedules, elevations, and specs. PDF, CAD, Bluebeam, Revit files all work fine. Dropbox and portal links too. We review the design documents, identify the full scope, and confirm what you need before we start. If something isn't clear in the drawings, we ask now, not after we've already priced it wrong.
PDF, DWG, DXF, CAD, Revit, Bluebeam all acceptedOpening Quantification
Our certified estimators go through your architectural plans opening by opening. Doors, windows, frames, specialty openings, all of it gets counted and cataloged. Nothing gets skipped and nothing gets estimated by assumption. Color-coded markups come back with the estimate showing exactly where each quantity was pulled from on your drawings, so you can check the work before it goes into your bid.
Color-coded markups included with every estimateHardware and Specification Assessment
We evaluate hardware requirements against your specs and building codes. This is where a lot of estimates fall short, they count the doors but don't account for the full hardware package. Hinges, closers, panic hardware, ADA devices, thresholds, weatherstripping. We do both, and we flag any hardware requirements that aren't fully detailed in the plans before pricing starts.
Building code compliance checked per opening type and occupancyCost Analysis and Pricing
We run material costs and labor costs through our cost database and industry leading estimating software, calibrated to your project location. Not national averages. Your market, your zip code. Labor rates in Phoenix don't look like labor rates in Boston and your estimate shouldn't pretend they do. We calculate material based on your material preferences and project specs. Got your own supplier quotes? Send them with the plans and we'll plug your numbers in instead.
Location-specific pricing, not national averagesBid-Ready Estimate Delivery
You get the estimate in Excel or whatever format you're working in. Material costs and labor costs broken out separately by opening type so you can actually read it without reformatting. Usually back in 24 to 48 hours. Sometimes faster on simpler residential scopes. If you're on a tight deadline, tell us upfront and we'll work around it. Want to see a sample before committing? Just ask, we'll send one over.
Senior review on every estimate before it goes outWhy Accurate Opening Estimates Actually Matter
Missed Items Become Change Orders
A missed curtain wall section, hardware not accounted for, fire rated assemblies overlooked on a healthcare project. Any one of those gaps creates cost overruns, change orders, and project delays. Human error in opening estimates is more common than most contractors want to admit, and the fix always costs more than the original estimate would have.
Material Shortages Mid-Job
Order the wrong quantity of door frames or specialty glazing and you're waiting on lead times mid-installation. Suppliers don't always have specialty openings in stock. A wrong takeoff that leaves you short on fire rated assemblies or custom glazing units can stall a project for weeks. Precise calculations prevent this. That's the whole point of an accurate takeoff.
Underbidding Eats Your Profit Margins
Win the job at a number that doesn't hold up and the project buys you. We've seen contractors bid aggressively on commercial openings scopes and discover the hardware alone blew their number. Accurate cost estimates protect your profit margins and let you bid competitively without leaving money on the table or bidding yourself into a loss.
Budget Overruns Kill GC Relationships
Nobody wants to be the sub who comes back mid-project with a change order for items that should've been in the original scope. It damages trust and it makes the GC think twice about calling you for the next project. Bid-ready estimates done right the first time keep those relationships solid.
Why Contractors Trust Blaze Estimating
Plenty of estimating companies are out there. Here's what actually makes the difference when you're working against a deadline.
Numbers You Can Bid From
Our 96% Accuracy Guaranteed is verified against actual project costs, tracked by contractors who used our estimates and followed what jobs came in at. The software we use is industry leading, but honestly, it's the experience behind it that makes the difference. Software doesn't catch a missing hardware spec or a curtain wall section that doesn't match the structural drawings. That's what years of doing this actually buys you. If the estimate isn't right, nothing else matters.
Fast Without Cutting Corners
Most opening estimates are ready in 24 to 48 hours. Sometimes faster. We know you're working against bid deadlines and we don't treat that as your problem to manage around us. Rush options available when you need them.
Division 08 Is What We Do
7,900+ completed opening projects across every construction type. Commercial curtain walls, healthcare fire door packages, industrial overhead systems, residential window takeoffs. We've seen the scopes that go sideways and we know exactly where to look before they do.
Certified Professional Estimators
Our certified estimators know building codes, fire rating requirements, ADA compliance, and energy performance standards across all states. That's not a given with every estimating company. It matters especially when your project is in a state or market you haven't worked before and you need numbers you can trust without double-checking everything yourself.

Frequently Asked Questions About Openings Estimating
All of them, basically. Doors, frames, windows, glazing, curtain walls, storefronts, skylights, overhead doors, roll-up doors, specialty openings. Residential, commercial, industrial, and institutional projects. Fire rated, security, energy-efficient, acoustic doors, whatever the project calls for. If it's a Division 08 item, we've estimated it before.
Yes. Always. Hinges, locks, closers, panic hardware, ADA devices, thresholds, weatherstripping, the works. Hardware specs matter for code compliance and we don't estimate doors without accounting for the full assembly. Hardware alone can add 15 to 25 percent to your total opening costs on commercial projects, so skipping it isn't an option.
Fire rated doors need the full UL-listed assembly: door, frame, hardware, and proper installation requirements. We estimate the complete assembly and flag the UL listing requirements for each opening. Substituting hardware on a fire rated door voids the rating, so we make sure everything listed meets the spec and matches what's required by building codes for your occupancy type.
Yes. Curtain walls and storefronts are a specific area of expertise for us. We work through structural glazing systems, pressure wall assemblies, rainscreen systems, and thermal break assemblies in detail. Honestly these are the openings where a wrong estimate hurts the most, so we're especially careful with them. Brackets, mullions, glazing units, sealants, all priced separately with their own line items so nothing disappears into a lump sum.
Your architectural drawings, door and window schedules, elevations, and any relevant specs. PDF is fine. CAD, Revit, and Bluebeam files work too. The more complete the design documents, the more accurate the estimate. We'll let you know during the initial consultation if anything is missing before we start, not after we've already priced it.
We can identify glazing systems, thermal break assemblies, and weatherstripping specs to meet energy code requirements. If LEED or other green building standards apply to your project, tell us upfront and we'll account for those opening requirements in the estimate. Energy-efficient glazing systems and thermal and glazed openings are a regular part of our commercial work.
Blast-resistant, bullet-resistant, and forced-entry-resistant doors require specific manufacturer specs and testing certifications. We work with certified manufacturers and know the relevant government security standards. High-security facilities have unique opening requirements and we know how to price them accurately. Send us the specs and security level requirements and we'll build the estimate from there.
Usually 24 to 48 hours from when we receive your complete documents. Simple residential takeoffs can come back faster. Large commercial projects with complex curtain wall systems or custom openings might take a bit longer, and we'll tell you a realistic timeline upfront. Rush turnaround is available if you're up against a hard bid deadline.
Yes. Our estimates are clean, itemized, and formatted clearly. If you need a specific format for permits, procurement, or bid submittals, just let us know and we'll adjust the deliverable. You can also send us your company template and we'll match it.
PDF, CAD, Revit, Bluebeam, and most standard plan formats work fine. Dropbox and portal links are no problem. Bid sets, design development drawings, construction documents, schematics, all of it. If you're not sure whether your format works, just send what you have and we'll confirm.
Mostly general contractors and door or window subcontractors. GCs use us to get the opening scope priced cleanly before their overall bid goes out. Subs come to us when their estimating volume outpaces what they can handle in-house. But we also work with developers who need pre-construction numbers, architects who want budget figures during design, and construction managers coordinating multiple trades under tight timelines. Basically anyone who needs to know what an openings scope costs before committing to a price.
