Don't Let a Renovation Wreck Your Finances: What Maine Homeowners Need to Know
Builders insurance for renovations is a specialized policy that protects your home, materials, and investment while construction work is underway — coverage your standard homeowners policy likely won't provide.
Here's the quick answer on what builders insurance for renovations typically covers:
- Physical structure — damage to the existing home and new construction in progress
- Materials and supplies — on-site, in transit, or stored off-site
- Theft and vandalism — including appliances and fixtures before installation
- Fire, lightning, and weather damage — during the construction period
- Soft costs — like architect fees, permit costs, and loan interest from delays
And what it typically does not cover:
- Floods and earthquakes (separate policies needed)
- Faulty workmanship or design defects
- Contractor tools and vehicles
- Worker injuries (requires workers' compensation)
Renovation season is busy across Southern Maine — from kitchen gut-jobs in Wells to full additions in Kennebunk and Biddeford. And whether you're a homeowner or a small business owner upgrading a property, the financial stakes are real.
Here's the problem most people don't see coming: your existing homeowners policy likely has gaps the moment a contractor sets foot on your property. Standard policies are built for day-to-day life at home — not for open walls, exposed rooflines, or $80,000 worth of cabinetry sitting on a job site.
One missed notification to your insurer, or one contractor without adequate coverage, can leave you personally on the hook for losses that run well into the tens of thousands of dollars.
This guide walks you through the best builders insurance options for renovation projects, what to look for in a policy, and how to make sure your Southern Maine property is fully protected from the first hammer swing to the final walkthrough.
Understanding Builders Insurance for Renovations
When you decide to breathe new life into an older home in Wells or add a master suite to your Portland property, you aren't just buying lumber and labor; you’re managing a temporary high-risk site. In the insurance world, builders insurance for renovations is often referred to as "Course of Construction" insurance. It is an inland marine policy designed to protect the "insurable interest" of those involved in the project.
In Southern Maine, where property values have remained robust through April 2026, the financial interest in a renovation can be massive. If a fire breaks out during a renovation, who pays for the half-finished work? Your standard homeowners policy might cover the existing structure, but it may flatly refuse to pay for the new framing, the uninstalled granite countertops, or the specialized labor required to start over.

How Builders Risk Insurance for Renovations Differs from Homeowners Policies
The most common mistake we see homeowners make is assuming their current policy is "good enough." While your homeowners insurance is great for a burst pipe in your finished kitchen, it often contains specific exclusions for "dwellings under construction."
Key differences include:
- Theft of Materials: Standard policies often exclude theft of materials that haven't been "permanently installed." If a pallet of premium flooring is stolen from your driveway in Biddeford, a builders risk policy covers it; a standard homeowners policy usually won't.
- Materials in Transit: Builders risk can cover materials while they are being transported to your site.
- Occupancy Gaps: Many homeowners policies become void if a home is vacant for more than 30 or 60 days. Major renovations often require you to move out, making a specialized policy essential.
When to Secure Builders Insurance for Renovations
Timing is everything. You should ideally have your policy in place before the first dumpster arrives or the first permit is pulled in Biddeford. If you wait until the project is 50% complete, many carriers will decline to offer coverage because they cannot inspect the "ground-up" quality of the work already done.
As a rule of thumb, we categorize projects into two buckets:
- Minor Renovations: Generally projects costing less than 10% of your home’s total insured dwelling value (e.g., a simple bathroom refresh).
- Major Renovations: Projects exceeding 10% of the dwelling value or those involving structural changes (e.g., moving load-bearing walls, adding a story, or foundation work).
If your project is "Major," most standard insurers will require you to pivot to a builders risk policy to maintain coverage.
What Does a Renovation Policy Actually Cover?
A comprehensive policy acts as a safety net for the unexpected. Whether it’s a late-season Maine ice storm or an accidental fire caused by a stray spark, you want to know your investment is safe.
Essential Endorsements for Builders Insurance for Renovations
Not all policies are created equal. Depending on the complexity of your project in Ogunquit or Kennebunk, you might want to add these specialized "riders" or endorsements:
- Inflation Guard: With material costs fluctuating, this ensures your coverage limit rises alongside the cost of lumber and labor.
- Equipment Breakdown: Covers expensive HVAC units or specialized machinery if they fail during testing or installation.
- Change Order Endorsement: Provides a 10-30% "cushion" in coverage limits to account for those inevitable "while we're at it" project expansions.
- Soft Costs: This covers financial losses that aren't physical, such as additional interest on construction loans, real estate taxes, and re-permitting fees if the project is delayed by a covered loss.
Common Exclusions to Watch For
Even the best builders insurance for renovations has limits. You won't find coverage for:
- Faulty Workmanship: If your contractor installs the shower pan incorrectly and it leaks, that’s a matter for their professional liability insurance, not builders risk.
- Wear and Tear: Rust, corrosion, or "normal" deterioration of materials left out in the elements.
- Employee Theft: If the contractor’s own crew swipes tools, this is usually excluded.
- Flood and Earthquake: Just like standard insurance, these require separate, dedicated policies—especially important for coastal properties in Southern Maine.
Determining the Cost of Renovation Insurance in Maine
We know what you’re thinking: "How much is this going to set me back?" In April 2026, the standard rule of thumb is that builders insurance for renovations costs between 1% and 5% of the total project budget.
If you are spending $200,000 on a major addition in Kennebunk, expect to pay between $2,000 and $10,000 for the policy, depending on the duration and scope. Several factors influence this price:
- Project Duration: A 6-month kitchen remodel is cheaper to insure than an 18-month whole-house reconstruction.
- Location Risks: Coastal properties in Ogunquit may face higher premiums due to wind and hail exposure.
- Materials Selection: Using fire-resistant materials can sometimes lower your rate.
- Occupancy: Is the house vacant during construction? Vacant homes are higher risks for theft and undetected water damage, which can bump up the cost.

Who is Responsible for Purchasing Coverage?
This is the "Who’s on First?" of the construction world. The short answer: It depends on your contract.
In many standard AIA (American Institute of Architects) contracts, the property owner is responsible for providing the builders risk insurance. However, some large general contractors include it in their bid.
Our advice? Even if the contractor says they have it, ask for a Certificate of Insurance (COI) and have your own agent review it. Better yet, purchase the policy yourself. When you are the "Named Insured," you control the policy, you receive the claim checks, and you know for a fact the premium has been paid.
The contractor’s general liability insurance covers their mistakes that cause injury or damage to other things; it does not necessarily cover the cost of rebuilding your project if a lightning strike burns it down.
Steps to Secure Your Investment Before and After Construction
Planning a renovation in Southern Maine involves more than just picking out tile. Follow this checklist to ensure you don't have a coverage gap:
- Notify Us Early: Call your agent the moment you start getting quotes. We can help you determine if your current policy can be endorsed or if you need a standalone builders risk policy.
- Vet Your Contractor: Don't just look at their portfolio. Ensure they have at least 5 years of experience (insurers prefer this over the minimum 2 years). Verify their General Liability and Workers' Compensation coverage.
- Update Your Inventory: Take "before" photos and videos of the entire house. If a wall is opened and a pipe bursts, you'll want proof of the original condition.
- Secure High-Value Items: If you aren't living in the home, move jewelry, small electronics, and heirlooms to a secure off-site location.
- Post-Renovation Reassessment: Once the "Certificate of Occupancy" is issued, your builders risk policy ends. You must notify your homeowners insurance provider immediately to convert the policy back to a standard form and update your dwelling limit to reflect the new, higher value of your home.
Frequently Asked Questions about Renovation Insurance
Is builders risk insurance required by law in Maine?
Technically, no. There is no state law in Maine mandating builders risk. However, your lender almost certainly requires it if you have a construction loan or a mortgage. Additionally, local municipalities in places like Wells or Biddeford may require proof of insurance before issuing certain permits.
What is the difference between major and minor renovations?
As mentioned earlier, the "10% rule" is the industry standard. If your renovation costs more than 10% of the insured value of the home, it's "Major." Also, any project that requires you to move out or involves structural changes—like moving a load-bearing wall or replacing a roof—is typically treated as a major project requiring specialized coverage.
How do I update my homeowners insurance after the project?
Don't let the "new home smell" distract you from the paperwork! Once the project is done, call us. We will help you recalculate the Replacement Cost of your home. If you just added a $150,000 sunroom and kitchen, your old coverage limit is now dangerously low. We’ll also look for new discounts; many insurers offer lower rates for homes with updated electrical, plumbing, or new security features.
