Home insurance for old homes begins with a questionnaire, spoken or silent: carriers underwrite century houses through a known list of questions about wiring, plumbing, heating, roof and structure, and the owner who prepares real answers, with documentation, gets quotes the unprepared owner is refused. This page walks the questions in the order they are asked, with what each answer means and how to give it well.
The systems questions
When was the electrical system updated, and is any knob-and-tube or aluminum branch wiring active? The answer decides eligibility with many carriers; an electrician's letter stating what is live and what is dead is the strong form of a good answer. What is the plumbing, galvanized, copper, PEX, and when replaced? Water claims drive old-house losses, and documented repipes move tiers. How is the house heated, and when was the plant replaced? Oil tanks, especially buried ones, draw their own questions, and a decommissioning record answers them. Each question rewards the same preparation: dates, invoices, and honesty, since a misrepresented system is a denied claim later.
The structure questions
How old is the roof, and what material? Slate and cedar draw specialist attention, and any roof past its material's rated life prices as a claim waiting; a recent tear-off with invoice is the best single answer on the sheet. Foundation and structure: stone foundations, sill condition and any correction history, with an engineer's letter where work was done. Additions and conversions: permitted or not, since unpermitted work is an underwriting problem and a claims fight. And occupancy: owner-occupied, rented, or vacant between, each a different product. Where full replacement terms are unavailable, the HO-8's functional replacement basis is the legitimate fallback, modern materials for old, understood before signing.
The questions to ask back
The owner's side of the conversation matters equally. Ask each carrier: is ordinance-or-law coverage included and at what percentage, since old houses trigger current-code rebuilding constantly; how is the roof settled, replacement cost or a depreciation schedule; what dwelling limit does their estimator produce, and does it honor plaster, true-dimension framing and craft trim, or flatten them; and which updates would move the quote next year, turning the renewal into a plan. Then the standing completions: the NFIP flood policy wherever water has a path, FEMA's FloodSmart reporting almost one-third of claims outside high-risk zones, and the CFPB's reminder that the lender requires the policy however old the house.
Questions people ask about home insurance for old homes
What will carriers ask about my old house?
The systems and structure list: wiring vintage, plumbing material, heating plant, roof age and material, foundation, additions and occupancy, each rewarding documented answers.
What is the strongest answer on the sheet?
A recent roof tear-off with invoice, followed by an electrician's letter on the wiring. Both move eligibility, not just price.
What should I ask carriers back?
Ordinance-or-law terms, roof settlement basis, whether their estimator honors craft construction, and which updates would move next year's quote.
What if no carrier offers full replacement terms?
The HO-8's functional replacement basis is the legitimate fallback, rebuilding with modern equivalents, chosen with the trade-off understood.
