Insurance Risks in Whole-Home Remodels: What Contractors Need to Know

A kitchen renovation is a discrete risk. A whole-home remodel — gut-renovation of an occupied house, room additions, new HVAC and electrical throughout, structural changes — is a different category of exposure entirely. The project value is higher, the number of trades on-site is larger, and the completed-operations tail is longer.

Most residential remodelers carry the same policy for a $15,000 bathroom job as for a $300,000 whole-home renovation. That's a gap worth understanding before a claim happens.

Why Whole-Home Remodels Carry Higher Risk

Extended timeline. A month-long project exposes you to fewer days of bodily injury and property damage risk than a six-month project. More days on-site means more chances for accidents, theft, and damage.

Structural work. Additions, load-bearing wall modifications, beam replacements, and foundation work carry completed-operations exposure that can surface years after project completion. Structural failures are expensive.

Multiple subcontractors. Whole-home remodels typically involve HVAC, plumbing, electrical, roofing, insulation, and finish subs — each bringing their own exposure and their own GL (or lack of it). If a sub's work fails, your GL may be called to respond.

Occupied or partially occupied homes. Some whole-home remodels are done in phases with the homeowner living in part of the house. Bodily injury to an occupant during active renovation is a real exposure.

Pre-1978 construction. Whole-home gut renovations frequently uncover lead paint, asbestos-containing joint compound or floor tile, and other materials requiring proper handling. Standard GL doesn't cover this exposure — CPL does.

The Completed-Operations Tail on Larger Projects

For a kitchen or bath renovation, the completed-operations exposure is real but relatively confined: tile waterproofing, plumbing connections, countertop installation. For a whole-home remodel, the exposure is much broader:

• Structural work: Headers, load paths, and connection details that passed inspection can still fail under unusual loads or seasonal movement.
• Roofing and flashing: New roofing and window flashing done during a renovation can fail years later, causing water damage.
• Electrical: Wiring defects may not cause problems immediately but can contribute to fires long after project completion.
• HVAC: Improperly designed or installed HVAC systems can cause moisture issues, mold growth, and energy-related claims.

A $1 million completed-operations aggregate is the floor for most markets. On whole-home projects above $200,000, $2 million aggregate is worth considering — especially if you're doing multiple large projects simultaneously.

Subcontractor GL Certificates Matter More Here

On a small project, a sub without GL is manageable. On a whole-home remodel with eight subcontractors, the gap compounds. If a sub's work causes damage or injury and their GL lapses — or was never in force — your GL and umbrella become the backstop.

Before starting a whole-home project:

• Require certificates of insurance from every sub naming you as additional insured
• Verify certificates are current (expiration dates are easy to miss)
• Check that sub GL limits meet project requirements
• Confirm subs carry workers' comp if they have employees

Some GC contracts require that your GL have no exclusion for subcontractor work. Know what your policy says before signing a sub agreement.

How Project Value Affects Your Insurance

Your GL policy typically includes a coverage note about operations that the policy was written to insure. If your GL was written for a remodeling contractor doing $500,000 in annual revenue and you take on a $400,000 whole-home project, that single project is a disproportionate share of your book.

Some carriers will want notification on unusually large projects. A few policy forms include a per-project limit or a requirement to notify the carrier for projects above a threshold. Review your policy before bidding your largest jobs.

What Coverage to Review Before a Whole-Home Remodel

GL: Check per-occurrence and completed-operations aggregate limits. Verify no subcontractor work exclusion.

Commercial umbrella: A $1 million umbrella above $1 million GL gives you $2 million per occurrence — still potentially insufficient for a large structural or fire claim on a high-value home. $2 million umbrella or higher may be appropriate.

CPL: Essential for any project involving demo in pre-1978 construction. Whole-home renovations in older homes almost always encounter lead or asbestos.

Workers' comp: Make sure your payroll reflects the project's labor intensity. Workers' comp is audited at year-end on actual payroll — underestimating at policy inception leads to a large audit bill.

Tools and equipment: A whole-home project ties up more of your tool inventory on a single jobsite for a longer period. Make sure your tools limit is adequate.

Talk to Your Agent Before the Project Starts

The best time to review your coverage for a large project isn't after the contract is signed — it's before you start estimating. We can review your current program, identify any gaps relative to the project profile, and shop additional coverage if needed.
