Many of our clients utilize Building Envelope Consulting Services to perform function and performance testing in the field after installation of window and glazing systems. During the course of testing it is not unusual to hear chatter regarding the cost of sealants, labor and materials being constantly on the rise. While recognising that these costs are part of the business we are in, many clients and installers realise to late that the cost of sealants is minimal compared to the risks of water intrusion.
Lets take an example of typical project sealant material costs:
Cost per tube: $8:00
Tubes used per window install: 4
Number of windows per project: 100,
So lets extrapolate the numbers, 4 X's 8 X's 100 = $3,200.00 in sealant costs for this project, typically we have 5% of stock left over at the end of the project that has a shelf life.
Unfortunately we see to often the caulker that for whatever reason has tried to "stretch" the last tube of sealant for that...
