I pretty much decided against it. Here's the reason so go ahead and tell me if you think I'm wrong because I very well could be. By the time the store manager asked me to do this it had already been over 9 months since the store had been cleaned. They typically only clean it once a year so it's not a great account to begin with and like I mentioned it just gets harder to clean each year. Really I think the carpet needs replacing, but I doubt they ever will.
Anyway, my thinking is 9 months for a heavily trafficked store is too long to wait for encap. It is a monster to tackle with a truck mount. The store manager doesn't want anyone else cleaning it. They're also super tight on their budget. I'm guessing encapping would take me nearly as long as hwe with my Boxxer w/o better equipment. My hope was to at least get them to do an encap perhaps at 6 months and hwe at 12 months. Seriously though I doubt he can get even that approved. Like I said, they're super tight. This place could use a quarterly cleaning at least.
You have to do what you think is best.
You will not be confident or happy with results unless you practice and see carpet after dry on any encap job. I did not offer any promises until I first tried absorbent pads and encap on jobs that were giving me problems. Your customer is demanding hwe and they should be stuck with crappy looking carpets and have to replace them every 8 years.
You should be able to clean carpet fast and easy with fiber pads then absobent pads using omega encap on stores that only clean once a year.
You said you are having more difficulty getting carpets to look good...been there done that.
I tried to find a solution and i did.
I have had no problem replacing my 4.8 hydramaster TM since I have had better results using the heavy duty fast trinity machine with wheels down. It can clean better any carpet I throw at it. Commercial carpet will never totally extract out because you will never get good airflow plus most accounts are cheap they do not want to do what warranty says and encap with a crb 4-6 times yearly and hwe twice yearly.
