Knob & Tube Wiring Removal
Old wiring shouldn't hold your home back. We safely remove knob and tube wiring so you can insulate, modernize, and protect your family.
Why Remove Knob & Tube Wiring?
Homes built before 1950 often contain knob and tube wiring — an outdated system that poses real risks today.
Fire Hazard
Knob and tube wiring lacks a ground wire and deteriorates over decades, creating a serious fire risk — especially when covered by insulation.
Blocks Insulation Upgrades
Massachusetts building code prohibits installing insulation over active knob and tube wiring. Removal is required before any Mass Save insulation work.
Insurance Issues
Many insurance companies refuse to cover homes with active knob and tube wiring, or charge significantly higher premiums.
How It Works
From assessment to insulation — we handle the entire process so you don't have to coordinate multiple contractors.
Free Assessment
We inspect your home's wiring to determine the scope of knob and tube present and create a removal plan.
Licensed Removal
Our licensed electricians safely remove all knob and tube wiring and replace it with modern, code-compliant Romex wiring.
Inspection & Certification
We coordinate the municipal electrical inspection and provide certification that your home is knob-and-tube free.
Insulation Installation
With the wiring cleared, we can proceed with your Mass Save insulation upgrade — often at 75–100% off.
Why Ecosave for Knob & Tube?
Most contractors do wiring OR insulation. We do both — which means one company, one schedule, one point of contact.
Frequently Asked Questions
How do I know if my home has knob and tube wiring?
If your home was built before 1950, there's a good chance it has some knob and tube wiring. Look in your attic or basement for white ceramic knobs and tubes running along joists. We offer free inspections to confirm.
Is knob and tube wiring dangerous?
Active knob and tube wiring can be dangerous — it has no ground wire, uses degraded insulation, and was never designed for modern electrical loads. The biggest risk is when it's buried under insulation, which can cause overheating.
How much does knob and tube removal cost?
Costs vary based on your home's size and the extent of wiring. We provide free assessments and work with you on financing options including the Mass Save 0% HEAT Loan.
Can I get Mass Save insulation with knob and tube?
No. Massachusetts code requires all active knob and tube wiring to be removed before insulation can be installed over it. That's why we handle both services — removal and insulation — as a seamless package.
How long does the removal take?
Most homes take 2–5 days depending on the scope. We minimize disruption and coordinate directly with your local inspector for the permit and sign-off.
