The Inspector Does.
We had three open DOB violations and a Health Department walkthrough in 72 hours. Blast showed up at 5 a.m., pressure-washed the entire loading dock and sidewalk vault, and we passed inspection the same afternoon. I've managed buildings in this city for 22 years and I've never seen a crew work that clean.

Grease-Blackened Sidewalk Vault
A Canal Street restaurant had accumulated eight years of kitchen exhaust grease on the sidewalk vault and cellar door. The DOB issued a §28-301.1 maintenance violation after a neighbor complaint. The Health Department walkthrough was 48 hours out.
Method
Hot water extraction + degreaser pre-treat
Hours on Site
6 hours
"The sidewalk went from black to concrete-gray in one morning. Inspector showed up, looked at it, wrote nothing down. First clean bill in three years."

Owner, Liang's Kitchen · Manhattan
Paint-Tagged Warehouse Facade
A 1920s Red Hook warehouse had accumulated three layers of graffiti tags across the entire Van Brunt Street elevation. The property owner faced a DOB graffiti-abatement notice and a co-op board deadline before a commercial tenant move-in.
Method
Chemical paint stripper + low-pressure brick wash
Hours on Site
14 hours over 2 days
"Our new tenant walked in and didn't know there had been graffiti. Blast matched the brick chemistry exactly — no ghost shadow, no damage."

Property Owner · Red Hook
Algae-Streaked Parking Structure
A 400-car LIC parking garage had gone three seasons without surface treatment. Black algae streaks covered 60% of the facade, and the ground-level drainage channels had compacted debris blocking storm compliance. A GC needed the site clean before the next trade.
Method
Surface cleaner array + soft wash algaecide treatment
Hours on Site
3-crew, 22 hours over 2 nights
"They worked 11 p.m. to 9 a.m. two nights in a row so we didn't lose a single billable hour for the other trades. That's the job."

Project Superintendent, Meridian Construction · LIC
