On the day your main is lined, we ask that you refrain from using your sanitary services (typically from 8:00 a.m. to 4:00 p.m.).
There will be minor traffic reconfiguration as well, but the contractor will likely do several hundred feet per day, so your daily travel should only be impacted for a few days.
There may also be an odor in the air due to the curing process.
A mailer will be sent out several months before construction, and a door hanger will be provided a day or two prior to construction with tips to help minimize odors indoors at your house/business.
