Before you sign a lease in Coppell
Check the address, not the zip code.
Ask each internet provider to confirm service at the exact suite. Coverage maps go by neighborhood, not by building.
Get the install date in writing.
A new business line has to be ordered and installed. Ask how long that takes before you pick a move date.
Ask the landlord about cabling.
Who has to approve running cable, and which walls, ceilings and closets can we get into?
Find the demarc.
That is the spot where the provider’s line ends and the building’s wiring begins. Know where it is and who owns what past it.
Plan a backup internet line.
A second provider or a cellular failover means one cut line is an annoyance, not a lost day.
Moving? Call us before you sign. (817) 265-5000. The question is free.

Billy Dunn and his partners have been our saviors in many situations. The Dunn's always answered every call we made whether it was an Emergency or one of us goofing something up. The BDunn & Company has been a very important factor that allowed our company grow for the past 20+ years.
