Chapter 2 – Prewire – Can I actually get away with this?

by Dave on Mar.12, 2010, under Cool Home Whizbang Stuff, Installation

If you are actually building your own home or using a custom builder, you are all set because you are in charge, but if you are buying from a semi-custom or tract home builder you need to carefully plan your approach.

Some tips to keep in mind as you arrange your project:

  • Builders are schedule driven and paid bonuses based on completion rates on a schedule – any project like this threatens their personal pocketbook.
  • Everything is negotiable – but you have to find the right person to negotiate with and do it at the right time. The sales person is the place to start. They are incentivised with making the sale and are generally willing to work out a deal to give you access if you lay that out up front.
  • Get your agreement in writing. Make sure that the limits of your actions are clearly spelled out, how long you need to do the work, your agreement to hold everyone involved harmless in the event of injury, your responsibility for damage, your agreement to follow and be held accountable to local and national codes.
  • Be prepared to smooth the way with the builder as well – as cheesy as it sounds, a case of beer is usually a good choice (end of the day, not cold so they don’t consume while they are working on your home). A couple pizzas a the opportune moment is also a good gesture. What you want is for the builder and his crew not to resent you – they need to call you to tell you if there is anything that is getting in their way or will interfere with inspections. Clear communication is key.
  • When you get the chance to actually do the work, speed is key. Take a couple days off work and get it done, don’t drag it out over multiple weekends. You are looking for the few days in between the framing inspection and when they come in to insulate.
  • While there are no specific codes that hold low voltage wiring to the same stringent levels as electrical, you should follow a few basic principles so as not to draw attention to your work. It should look as if a professional installed it under the direction and supervision of the builder:
    • All boxes should be standard height (match switch or outlet heights)
    • All wires should be secured (stapled, tied or hung) within 6” of a box, supported horizontally every 2’ and vertically every 3’.
    • All wires should be out of the way of drywall installers and with large bundles or close to the surface, metal plates installed.
    • At the media cabinet, wires should be neatly gathered and coiled and secured like you did at the boxes. Finally, be sure to plan the finish work. The media cabinet does not have to be completed prior to final inspection if it is not in a finished space, but all room boxes at least need a blank cover plate. If you are responsible for phone/TV outlets as part of your deal you need to terminate those using keystone plates prior to final inspection.

So, what can go wrong?

I’ve had plenty of folks say their builder (or home company) was not willing to work with them or insisted that they only allow work from a licensed professional. Low voltage wiring requires no license or certification from the government so the excuse is hollow. The best advice I can give is that you MUST be prepared to walk away from the deal. I’ve never had anyone tell me they could not come to some arrangement although there are a lot of painful stories.

A good negotiating technique is to volunteer to take on the network, phone and cable labor and materials if they let you do the rest of the low-voltage pre-wire. That can be worth $1000 or more to them as they have to pay a low voltage company to come in and do the basics.

My own experience with my last home was particularly distressing. I ended up paying extra for basic structured wiring (2 RG6, 2cat5) to each room through the builder, but clearly I couldn’t stop there. So I went in one night with the “general knowledge” of the builder and installed just a little extra wire. 3 1000’ spools of Cat5 and 4 500’ spools of RG6 later I was done. Unfortunately I had to go off on a business trip for the next week, intending to finish, secure, and tidy up my work the following weekend. I returned to find all my wire neatly coiled in the middle of my living room floor along with a note from the builder that they had to do an inspection while I was gone and they failed because the city electrical guy objected to all the loose hanging wires in the basement. The builder had left me a message (which I missed) and ended up having to get his electrician in to clean it up. The cleanup was catastrophic to my plans. As insulation was the very next day, I had no time to renegotiate and get back in there. The best I could do was to get permission to put in a couple of conduit chases so I could get wires to the different sections of my home from the basement. What did I learn? Communication, smooth the waters with the builder, do not get in their way, and always keep in mind what incentivises them.

But, in the end, it is your home, they all work for you. Do not back down.
