Hi Lbonwell -- I can help with your service extension. Our construction team does not have a direct number however I can get you in contact with them. Please send me a PM with your name, full service address, and either phone number or account number. I will also need to know if you are switching your service from this apartment to the house or if you're wanting service in both the house and the apartment.
Click my name (ComcastZach) and click Private Message Me.
