Terrific job professionally. Courteous and professionally competent
Only concern was they removed their masks at some point in process.
As an 87 year old , I need to be careful of the virus. Will keep the area isolated and aired out for 72 hours and will sanitize thereafter
Air circulation also turned off.
Masks not an issue when they were working outside, but a concern in confined basement
Same issue with the technician who repaired the broken gas line a few days ago.
He was also very good at the job, but occasionally dropped his mask inside
