FAQ

Low voltage estimating: common questions

Which drawings do you need?

Is fire alarm a separate takeoff?

It can be included with low voltage or done on its own, whichever matches your scope.

Can you price equipment?

Yes. Send your supplier pricing or preferred manufacturers and we build it into the Excel file.

A single-trade takeoff is $99. Full priced estimates are $249 for residential or remodel and $499 for custom homes or commercial. Monthly plans start at $299 for 4 takeoffs, and unused takeoffs roll over.
