What Affects the Cost of Building Envelope Consulting
No two buildings are priced the same. Here's what moves the fee up or down for testing, investigations, QA and assessments, and how we keep it predictable.
What Moves the Fee
Size and How Many Systems
A single storefront leak is a different job than a 300-unit building with roofs, balconies and windows. We scope to the systems that matter to your question.
Access
Lifts, swing stages, roof hatches, occupied units and escorts all change how much ground we can cover in a day. On new construction the contractor usually provides access and lifts.
Number of Visits or Tests
QA is priced per site visit and testing per test location, so the count drives the fee. Fewer, well-timed visits beat many short ones.
Travel
We work nationwide. Travel is estimated up front, and adding services to the same trip shares that cost.
Schedule and Weather
Infrared and water testing need the right conditions. Night roof scans, rain delays and tight closing dates all shape the plan.
What the Report Needs to Do
A field report for the contractor, a condition report with 10-year costs for a board, or a forensic report with findings and opinions each take a different amount of office time.
Documents Available
Drawings, submittals and repair history let us test the right places first. Without them we spend more time finding out how the building was built.
Retests and Changes
If a test fails, the opening is retested after the fix. Short-notice cancellations and unprepared sites add cost, so we confirm readiness before we travel.
What Matters for Each Service
Window and Storefront Water Testing
- Number of openings tested
- Chamber testing (AAMA 502 / 503) or nozzle testing (AAMA 501.2)
- Water supply and access to both sides of each opening
- Retests after a failure
Forensic Water Intrusion Investigation
- How many leak areas and how long they've been going on
- Water testing, infrared and test cuts needed to prove the cause
- A contractor to open and close test cuts
- Repair recommendations only, or a full remedial scope
Electronic Leak Detection
- Membrane area
- Membrane type and whether there is a conductive layer under it
- Low-voltage or high-voltage method
- Overburden that has to be moved
Infrared Thermography
- Roof area and number of roofs
- Drone or walking scan, and whether a night scan is needed
- Weather that allows a valid scan
- Cores or moisture readings to confirm wet areas
Construction QA Site Visits
- Number of visits through construction
- Design review of the details before work starts
- Water tests and mock-ups added to visits
- Travel per visit
Property Condition Assessments
- Building size and number of buildings
- Document review and interviews
- Cost tables for immediate needs and Years 1–10
- Closing or board deadlines
Building Envelope Design Review
- Number of sheets and details
- Review rounds as the drawings develop
- Submittal and RFI review during construction
Blower Door Testing
- Building volume and number of zones
- Preparing the building for the test
- Infrared or smoke to find the leaks
- Retest after repairs
How We Keep It Predictable
A Written Proposal First
Every job starts with a proposal that lists each visit, test and report as its own line, so you see what you're paying for.
Optional Items Kept Separate
Add-ons are priced on their own lines. You pick them before work starts, not after.
Travel Estimated Up Front
For out-of-town work, travel is estimated in the proposal, and services on the same trip share it.
Scoped to the Question
We test what answers your question, not every square foot of the building.
How much does building envelope consulting cost?
It depends on the building, the access and how many visits or tests the question needs. Tell us about the project and we'll reply within one business day with next steps and a written proposal with a fee for each part of the work.
Do you charge hourly or a fixed fee?
Most work is quoted as fixed fees per visit, per test or per report, with travel estimated up front. Hourly is used for open-ended items such as extra meetings or submittal review, and the proposal says which is which.
Are optional items priced separately?
Yes. Optional services are listed on their own lines in the proposal, so you choose what to include before work starts.
How can we keep the cost down?
Send drawings and submittals early, schedule testing when the first units are installed, have access, lifts and water ready on test day, and group work into fewer trips.
Who pays for a failed window test retest?
In JEC proposals, the responsible contractor is liable for retest costs; JEC invoices the client, who back-charges the contractor.
