Knob & Tube Remediation
Finlayson Electric safely removes and replaces knob and tube wiring — and handles the insurance documentation your provider requires.
Knob and tube wiring was the standard in American homes from the 1880s through the 1940s. It did its job for decades — but it was never designed to handle the electrical loads we put on our homes today. Air conditioners, EV chargers, smart appliances, home offices — modern living demands far more than this old wiring can safely deliver.
Beyond the load issue, knob and tube wiring has no ground wire, degrades over time, and is frequently found buried under insulation — a combination that dramatically increases fire risk. Most homeowners insurance providers in New Hampshire and Massachusetts will either refuse to cover a home with active knob and tube wiring, or charge significantly higher premiums until it’s removed.
At Finlayson Electric, we handle knob and tube remediation cleanly, thoroughly, and with full documentation — so you’re protected on all fronts.
What's Included
Full Remediation, Start to Finish.
Inspection & Assessment
Before any work begins, we conduct a thorough inspection of your home's existing wiring to identify all active knob and tube circuits, assess their condition, and give you an honest picture of what remediation will involve.
Knob & Tube Removal
We safely remove all active knob and tube wiring from your home — systematically and with minimal disruption to walls, ceilings, and finished spaces wherever possible.
Modern Wiring Installation
Every circuit we remove gets replaced with modern, grounded wiring that meets current NEC code standards and is built to handle your home's actual electrical demands.
Panel Assessment & Upgrades
Knob and tube remediation often reveals that the existing electrical panel also needs updating. We assess your panel as part of the process and recommend upgrades where necessary.
Insurance Compliance Documentation
We provide the documentation your insurance provider requires to confirm the work has been completed by a licensed electrician and that your home's wiring meets current standards.
Permits & Inspections
All knob and tube remediation work is permitted and inspected to ensure full code compliance — protecting you, your home, and your insurance coverage.
This Isn't a "Deal With It Later" Kind of Problem.
Knob and tube wiring doesn’t fail gradually — it fails suddenly. And when it does, the consequences can be severe. Here’s what you need to know:

It's a Fire Hazard
Knob and tube wiring has no ground wire and relies on open-air cooling to dissipate heat. When covered by insulation — as it often is — that heat has nowhere to go.

It's Uninsurable
Many insurance providers in NH and MA will not issue or renew a homeowner's policy on a property with active knob and tube wiring — or charge significantly higher premiums.

It Limits Your Home
Modern appliances, EV chargers, home offices, and additions all require more electrical capacity than knob and tube systems can safely provide.

It Affects Home Value
Buyers, home inspectors, and lenders all flag knob and tube wiring. Addressing it protects your asking price and prevents delays at closing.

If you don’t call them, you’re doing yourself a disservice. J BachTrustindex verifies that the original source of the review is Google.

Kerry BolesTrustindex verifies that the original source of the review is Google. Scott was prompt and professional, not only with the jobs but with the estimate as well. I couldn’t have asked for a better electrician to complete the work. Scott and crew added a whole house surge protector, added an outlet in a bedroom and installed a motion sensor light on the garage! Thanks again Scott!!! Alexis WinnellTrustindex verifies that the original source of the review is Google. Scott and his team came out in an emergency when a transformer blew and an entire building lost power! With my being a property manager, it is important that my vendors are knowledgeable, responsive and fair! Scott is all of that! I have and will continue to work with Finlayson Electric on multiple projects as he is my go to electrician! . Lia TaniguchiTrustindex verifies that the original source of the review is Google. Johnni installed an EV charger for me. It was tricky because he had to add it to a jam-packed breaker box, run a line all the way to the other side of the house, and deal with the fact that I had ordered the wrong item. He was patient, knowledgeable, creative about problem-solving, did high-quality work, and was consistently pleasant to deal with even though the job took a couple of unexpected turns. He also ended up taking care of a few other electrical jobs for me while he was there. Brian coordinated the whole thing, was incredibly communicative and responsive, and was on top of everything. Would 100% recommend them and will definitely use them in the future for any electrical work I need! Makenzie O’LearyTrustindex verifies that the original source of the review is Google. I hired Finlayson Inc to install a massive ceiling fan in a cupola with very high ceilings. The owner, Scott showed up when he said he would, did a great job, and made quick work of the install. I’m extremely satisfied with the way the it came out. He was punctual, professional, and very reasonably priced. While he was there, he inspected my breaker panel and made recommendations on a future panel upgrade, which I will be sure to hire Scott for my future electrician needs, and highly recommend him to anyone needing residential electrical work.Google rating score: 5.0 of 5, based on 26 reviews
