When you hire Kuhlman™ you'll have a modern, safe, code-compliant electrical system—without turning your home into a construction zone. Schedule a Knob & Tube evaluation with Kuhlman Electric™ and take the first step toward a safer, properly powered home.

Home inspectors and buyers routinely flag Knob & Tube wiring as a major concern. Because it increases fire risk, limits electrical capacity, prevents proper insulation, and can make insurance difficult to obtain, many buyers see it as a serious liability. As a result, homes with Knob & Tube often face fewer offers, delayed sales, reduced purchase prices, or costly credits at closing.Although replacing Knob & Tube wiring solves many of these issues, homeowners often hesitate for two reasons. Kuhlman Electric can help address both.

Cost: Kuhlman™ will help determine if your home qualifies for assistance through Mass Save, and we also offer financing options to reduce the upfront cost. In most cases, the improved safety, insurability, and resale value of your home outweigh the investment.

Early in his career, Jesse Kuhlman — a third-generation Master Electrician and owner of Kuhlman Electric™ — recognized that homeowners needed clear guidance on this complicated subject. What began as a homeowner’s guide became an 80-page book published on Amazon. It details the history of Knob & Tube wiring, safe methods for replacing it, and how to confirm any electrician you hire has the necessary skills to do the job.
