Portland, Maine Contractor Insurance for the Peninsula, the Suburbs and the Islands
Portland is Maine’s largest city, and most of its character is packed onto a narrow peninsula between Back Cove and Casco Bay. The brick buildings of the Old Port went up after the Great Fire of 1866, the West End is lined with Victorian homes and grand Italianate houses, and Munjoy Hill mixes older multifamily buildings with new condos that take advantage of the water views. Demand for housing has pushed builders to add accessory units, convert older buildings, and fill vacant lots wherever zoning allows.
Out in Casco Bay, Peaks Island and the other islands bring a kind of job most contractors never see: materials, tools, and crews have to ride the ferry or a barge before work can start. Portland’s contractors include restoration carpenters, roofers who handle snow loads and ice dams, licensed plumbers and electricians, heating technicians who install boilers and heat pumps, and painters and masons. Maine does not license general contractors or roofers, so homeowners often judge a company by its insurance certificate, its written contract, and its reputation around town.
Portland Contractor Coverage From a Contractor-Founded Broker
Because Maine leaves general contracting unlicensed, insurance is often the main proof of professionalism a Portland homeowner or condo association sees. PBIB is an independent brokerage started by former contractors, and we compare A-rated carriers in admitted and non-admitted markets for Cumberland County firms. We build general liability with limits that suit valuable peninsula homes and the condo boards that manage them. We keep workers’ compensation in place for every employee, as Maine requires, and insure trucks on commercial auto, including vehicles that ride the ferry to island jobs. Larger restorations often need builder’s risk and excess liability, and we finish programs with tools and equipment coverage and license and permit bonds.
Island job coverage: confirm that tools, materials, and trucks stay covered while on ferries, barges, and island job sites.
Condo association certificates: additional insured wording for the boards that manage Munjoy Hill and West End buildings.
Snow and ice claims: review how your liability policy handles ice dam leaks and falling snow from roofs you worked on.
Historic restoration limits: higher per-occurrence limits for work on 19th-century homes with irreplaceable trim and plaster.
Licensed trade support: certificates for plumbers, electricians, and fuel-licensed heating technicians when owners request them.
Accessory unit builds: builder’s risk for ADUs and garage conversions going up across the city.
Seasonal crew planning: accurate payroll estimates when summer work doubles your crew.
Portland Contractor Insurance by Trade
Roofing Contractors
Heavy snow, ice dams, and coastal wind are hard on Portland roofs. Roofing contractor insurance should include liability with completed-operations coverage, workers’ comp, and tools coverage.
General Contractors and Restoration Builders
Peninsula homes and condo buildings bring tight lots, shared walls, and owners who expect high limits. Builder’s risk protects larger renovations.
Heating and HVAC Contractors
Oil, propane, and gas heating technicians are licensed by the Maine Fuel Board, and heat pump installations keep growing. HVAC contractor insurance covers fire and carbon monoxide claims.
Plumbing Contractors
Maine licenses plumbers at the state level. Plumbing contractor insurance protects against frozen-pipe and water damage claims in older homes.
Electrical Contractors
Electricians hold state licenses and handle panel upgrades, EV chargers, and heat pump circuits. Electrical contractor insurance covers fire and property damage.
Artisan Contractors
Carpenters, painters, and masons restore millwork, clapboards, and brick. See our artisan trade insurance page.

Why Portland Contractors Choose PBIB
Proof That Wins Work
With no general contractor license in Maine, Portland homeowners and condo boards look closely at insurance certificates. We help you carry limits and endorsements that match the homes you work on, and we send certificates quickly, so your paperwork shows the same professionalism as your craftsmanship and helps you win the next job.
Coverage for Island Jobs
Peaks Island and the other Casco Bay islands mean ferries, barges, and equipment left on site for days. We confirm how your auto, tools, and liability policies respond while crews and gear are in transit and on the islands, so a long trip across the bay does not open an unexpected gap.
Winter Claim Awareness
Ice dams, frozen pipes, and snow sliding off roofs create claims that can surface months after a job. We review completed-operations coverage and water damage terms before winter, so you know how your policy responds when the first nor’easter tests your work. We also confirm how your policy handles roof snow removal jobs.
Brokers Who Came From Construction
Before opening PBIB, our founders spent their careers in the trades. We understand bids, change orders, and audits, and we explain coverage in plain words. When a claim comes in or a condo board needs a certificate before Monday, you work with people who know the job. That experience shows when a deadline is close.

It can pay for injuries to others and damage to a client’s or neighbor’s property caused by your work, including damage that shows up after the job.
Does a heating technician in Portland need commercial auto?
Service vans carrying boilers, tanks, and heat pump units around the city should be on a business auto policy, especially if they ride the ferry.
