Will Insurance Cover a House with Knob and Tube?
Some insurers refuse or limit coverage for active knob-and-tube wiring. Others cover it only after it's replaced or inspected.

Whether the wiring is active
Knob-and-tube still carrying power to outlets or fixtures is what concerns insurers. If it's been disconnected and replaced with modern wiring, even if some old wiring is still physically in the walls, most insurers treat the house as rewired and underwrite it normally.
Why the insurer cancelled
The non-renewal letter should state the reason. If it names the wiring specifically, that's what the next insurer will ask about too. If it names something else, like roof age or claims history, the wiring may not even be the real obstacle to replacing coverage.
An electrical inspection
A recent inspection report showing the wiring's condition and what's active can satisfy some insurers even without a full rewire. It won't work for all of them, so check whether the insurer you're applying to accepts inspection in place of replacement before paying for one.
Your deadline and your lender
The cancellation letter gives the exact date coverage ends, set by your state's notice rules, not a general guess. If there's a mortgage, the lender needs continuous coverage by that date or it can force-place a policy at a higher cost than what you'd arrange yourself.
Insurers differ a lot on knob-and-tube, and one declining or raising the price doesn't mean they all will. Some ask for a full rewire, others accept an inspection, and some won't touch the wiring issue at all if it's disconnected. With a deadline from the lender and the old policy ending, checking what else is available now is the only way to know what this house actually qualifies for.
What does rewiring actually cost and is it worth it before shopping again
Replacing knob-and-tube throughout a house is a bigger job than most repairs homeowners have faced. It means opening walls and ceilings in every room the old wiring reaches, not just swapping a panel or an outlet. The price depends on the house's size, how accessible the wiring is, and local labor costs, and an electrician who's actually inspected the house can give a number that a general estimate can't.
A full rewire isn't always necessary to get covered. If an inspection shows the active knob-and-tube is limited to one area, like an attic or a single addition, some electricians can disconnect and replace just that portion rather than the whole house. That costs less and may be enough to satisfy an insurer that only objects to wiring still carrying current. Whether a partial fix is acceptable depends on the insurer, so it's worth knowing which insurers accept partial work before paying for any of it.
Timing matters here. A rewire can take weeks to schedule and complete, and the cancellation letter has a fixed date on it. If that date is close, waiting on an electrician before shopping for coverage risks a gap, and a gap is what triggers a lender's force-placed policy. It's often faster to find out which insurers will accept the house as it stands now, even at a higher price, and revisit the rewire afterward if it would open up better options later.
The house's age plays into this even after the wiring is settled. Older homes often carry other things insurers ask about, like the plumbing type, the panel's amperage, or the roof's material and age. An inspection or rewire that addresses the wiring won't clear those if they're also part of why coverage was declined. The non-renewal letter is the place to check what else was named, since fixing only the wiring won't help if something else is still working against the application.
Should the wiring be fixed before shopping for coverage again
Rewiring an entire house is a much bigger job than most people picture when they hear the word. It means opening up walls and ceilings in every room the old wiring runs through, not just updating a panel or swapping a few outlets. What it costs depends on the size of the house, how easy the wiring is to reach, and local labor rates, and only an electrician who has actually looked at the house can give a real number.
A full rewire isn't always what it takes to get covered. If an inspection shows the active knob-and-tube is confined to one part of the house, an attic, a single addition, some electricians can disconnect and replace just that section instead of rewiring the whole place. That costs less and may be enough for an insurer whose only concern is wiring still carrying current. Whether a partial fix passes depends on the insurer being applied to, so it's worth finding that out before paying an electrician to do the work.
Timing is the other piece of this. A rewire can take weeks to schedule and finish, and the cancellation letter has a fixed date on it that doesn't move for that. If the deadline is close, waiting on electrical work before looking for a new policy risks a gap in coverage, and a gap is exactly what triggers a lender's force-placed policy. It's often faster to see which insurers will take the house as it is now, even at a higher price, and deal with the rewire afterward if it opens up cheaper options down the line.
The age of the house doesn't stop mattering once the wiring is addressed. Older homes often carry other things insurers ask about too, the type of plumbing, the electrical panel's capacity, the roof's age and material. Fixing the wiring won't clear any of those if they also played a part in the non-renewal. The letter itself is the place to check what else was listed, since wiring may not be the only thing an application needs to answer for.
Before the deadline
Check your non-renewal letter for the exact date and everything it names, not just the wiring. Then see which insurers still cover the house as it stands, so you're not stuck waiting on a rewire to keep coverage.
