They are working on street markings
Last week sub contractors came to mark the white lines corner Guelph and park heaven they started at 11:30pm until 12:45am making huge noise once done marking was terrible
Sunday they came back 3 am to remove part of painting they did and in doing so they sandblast the old paint

Ok, definitely unacceptable to have noise at that time.

We apologize for the inconvenience. Every year the city must re-do the painted lines that adorn our streets. The work needs to be done at night due to the 2-hour mandatory drying time. You can expect a maximum of 2 days of work per intersection. We thank you for your understanding.

Thank you for prompt reply

Understand and have no issues on marking of street corner Guelph and park haven but does this type of work need to be done at 3am?
Your subcontractor did the initial work ( marking paint at 11:30 ( late but still could live with that ) but last Saturday they came back to sandblast some of the work they had done due to poor quality painting before at 4:00 am using sandblast gun and compressors
I think that such work using noisy equipment could have been done much earlier
Also I would invite you to come and see what terrible work done,

Thank you for your comment. Your feedback has been reported to the Engineering Department.
