Home Renovation & Insurance: What to Update Before, During & After

A kitchen remodel, new roof, or addition changes your home's replacement cost — and your insurance needs. Here's what to tell your agent at every stage of a renovation.

Renovations are the #1 cause of homeowners being underinsured. You spend $40,000 on a kitchen remodel but never update your insurance. Then a fire destroys the kitchen. Your policy pays based on the OLD kitchen value — leaving you $30,000+ short.

Before the Renovation

  • Call your agent: Describe the project scope and estimated cost
  • Update replacement cost: Increase dwelling coverage to reflect the post-renovation value
  • Verify contractor insurance: Get a certificate of insurance showing general liability ($1M+) and workers comp
  • Ask about builder's risk: For major projects ($50K+), you may need additional coverage during construction
  • Check your policy for construction exclusions: Some policies limit coverage during renovations

During the Renovation

  • Document everything: Photos and videos of work in progress
  • Keep receipts: Materials, labor, permits — all documentation
  • Monitor contractor work: Ensure proper permits are pulled
  • Watch for hazards: Open walls, exposed wiring, and construction debris increase risk
  • Liability awareness: Workers and delivery people on your property = increased liability exposure

After the Renovation

  • Update your policy: Final cost may differ from estimates — adjust dwelling coverage
  • Update your home inventory: Document new appliances, fixtures, and finishes
  • Keep all documentation: Contracts, receipts, permits, photos, warranty info
  • Ask about discounts: New roof, updated electrical/plumbing, smart home features may reduce your premium

Renovations That Can LOWER Your Premium

  • New roof: 10-25% savings (especially impact-resistant shingles)
  • Updated electrical: Replacing old wiring reduces fire risk
  • Updated plumbing: Replacing galvanized or polybutylene pipes reduces water damage risk
  • New HVAC: Modern systems are less likely to cause fires or water damage
  • Smart home/security: Water leak sensors, monitored alarm, smart smoke detectors: 5-20%
  • Wind mitigation (coastal): Hurricane straps, impact windows: 10-40% in Florida

Renovations That Increase Your Premium

  • Swimming pool: Significant liability increase
  • Trampoline: Many carriers exclude or surcharge
  • Wood-burning stove/fireplace: Increased fire risk
  • Home office with client visits: May need business endorsement
  • Short-term rental conversion: Requires different policy type entirely
Bottom line: Tell your agent about every renovation — before it starts. Increased replacement cost means increased coverage. Some renovations save you money on insurance. All of them need to be reflected in your policy to ensure you're properly covered.

Frequently Asked Questions

Do I need to tell my insurance company about a renovation?+
Yes — always. Any renovation that changes your home's value, structure, or risk profile should be reported. A $30,000 kitchen remodel increases your replacement cost by $30,000. If you don't update your coverage and have a fire, you could be underinsured by that amount. Some policies have a 'under construction' exclusion that can deny claims during major renovations.
Does a renovation increase my insurance premium?+
Usually slightly — because your home's replacement cost increases. A $50,000 renovation might increase your premium by $100-$200/year. However, some renovations DECREASE your premium: new roof (10-25% savings), updated electrical (reduced fire risk), updated plumbing (reduced water damage risk), and security/smart home upgrades (5-20% discount).
Do I need a builder's risk policy for a renovation?+
For major renovations ($50,000+, structural changes, additions), yes — consider a builder's risk policy or endorsement. This covers materials, equipment, and the structure during construction. Your standard homeowners policy may exclude or limit coverage for damage during construction. Your contractor should also have their own insurance.
What if my contractor damages my home during renovation?+
Your contractor's insurance (general liability and workers comp) should cover damage they cause and injuries to their workers. ALWAYS verify your contractor has insurance before work begins — get a certificate of insurance. If they're uninsured and cause damage, you'd have to file on your own homeowners policy.
