Upgrading old and potentially dangerous knob-and-tube wiring in your business can seem like an expensive and daunting task. However, with some planning and know-how, you can upgrade your wiring safely and affordably. As the owner of an older building, I learned how to do this the hard way through trial and error. Let me share what I've learned so you can upgrade your wiring without breaking the bank.
Assess the Scope of the Project
The first step is to thoroughly inspect your building to understand the full scope of the project.
-
Hire an experienced electrician to conduct an assessment. They can identify all areas where knob-and-tube wiring exists, test it for safety issues, and determine what needs to be replaced.
-
Ask them to provide a detailed quote for the full wiring replacement project so you understand the potential costs.
-
Consider any upcoming renovations or areas of your building that will need electrical work. It may make sense to combine projects to save money.
Develop a Phased Approach
Once you have a full assessment, break the project into phases so it is more affordable.
-
Start with the most critical updates - Address any immediate safety issues and upgrade wiring in your most frequently used areas first.
-
Prioritize accessibility - Wiring that is easily accessed, like a basement or workspace, is a good next phase.
-
Combine with other renovations - When doing any other construction projects, have wiring replaced at the same time.
-
Leave difficult areas for last - Wiring inside walls can wait until you are ready to open up walls for other updates.
Take Advantage of Financial Incentives
Check with local utilities and government agencies to find any financial incentives available for electrical upgrades.
-
Rebates - Some utility companies offer rebates for replacing old wiring as it improves energy efficiency.
-
Tax incentives - There may be tax credits, deductions, or exemptions available. A tax professional can advise you on any options.
-
Grants - Nonprofits or government agencies may have grants for improving outdated wiring in historic buildings.
-
Low-interest financing - Some banks and agencies offer low-interest loans for wiring upgrades. Good credit will help you qualify.
Work with an Experienced Electrician
While a big name electrical company may seem like the obvious choice, you can actually save significantly by hiring a qualified independent electrician.
-
Get referrals - Ask local contractors, suppliers, or your local builders association for references.
-
Check reviews - Online reviews can help identify reputable electricians known for quality work.
-
Get multiple bids - Don't just go with the first bid. Get quotes from 3-5 electricians to find the best value.
-
Ask about pricing - Inquire if they offer discounts for bulk work or provide lower rates for simple jobs.
-
Provide assistance - Offer to help with demolition, material purchases, or cleanup to reduce labor costs.
Use Cost-Effective Materials
You can supply inexpensive wiring and accessories to help reduce the electrician's material costs.
-
Buy wire rated for commercial use. 12/2 NM cable is a common, affordable option.
-
Purchase bulk quantities of wire, boxes, and other supplies at home improvement stores.
-
Specify less expensive commercial-grade fixtures vs designer lighting. Function over form cuts costs.
-
Provide plastic or fiberglass junction boxes which cost much less than metal versions.
-
Offer to salvage and reuse existing conduit, breakers, switches, and outlets that are in good shape.
Carefully Budget and Fund the Project
With large construction projects, unforeseen costs often arise. Have a plan in place to cover any budget overages.
-
Get the electrician's best estimate for each phase upfront so you can plan finances.
-
Pad each phase estimate by 10-15% to have a contingency fund for surprises.
-
Only take on one phase at a time so you don't deplete working capital needed to operate your business.
-
Explore financing options in advance if you need access to extra funds quickly.
-
Set aside a little from each paycheck to build up a reserve for the upgrades over time.
By following these strategies, you can tackle that intimidating wiring project affordably, even on the tightest budget. Let me know if you have any other questions! I'm happy to share more details on what has worked for me as I've navigated upgrading my own building.
