Insurance coverage for a deck and patio business, compared to its real cost
Deck and patio insurance runs on named policies, real premium drivers, and the real cost of one torn-up ledger board, failed footing, or rotted joist.
What to take away
- Commercial general liability for a deck and patio business typically runs $900 to $4,500 USD a year in the United States at a $1M to $2M limit, and $1,200 to $5,000 CAD in Canada at $2M. Revenue, payroll and subcontracted labor set the band.
- Completed operations is the part of that policy that pays when rot behind a ledger board surfaces two winters after the final invoice.
- Replacing a rotted ledger board or a settled footing costs the low thousands. The injury claim that can follow a collapse does not. That gap is the real cost of going bare.
- Builder's risk covers the structure while it goes up and stops at completion. It never replaces completed operations.
- Raise the deductible before you shop carriers. It moves the number more than a new broker does.
What insurance costs by revenue band
Premiums are priced on annual revenue, payroll, and how much labor you subcontract. Every figure below is an illustrative range, not a quote, and the table is labelled by currency and market.
| Market | Annual revenue | CGL limit | Illustrative annual premium |
|---|---|---|---|
| US | Under $150,000 | $1M | $900 to $2,000 USD |
| US | $150,000 to $500,000 | $1M to $2M | $2,000 to $4,500 USD |
| US | $500,000 to $1M | $2M | $4,500 to $9,000 USD |
| US | Over $1M | $2M to $5M | $9,000 USD and up |
| Canada | Under $150,000 | $2M | $1,200 to $2,500 CAD |
| Canada | $150,000 to $500,000 | $2M | $2,500 to $5,000 CAD |
| Canada | $500,000 to $1M | $5M | $5,000 to $10,000 CAD |
| Canada | Over $1M | $5M | $10,000 CAD and up |
Add-ons sit on top of the liability premium. Commercial auto runs roughly $2,000 to $4,000 per vehicle a year in both markets. Tools and equipment cover adds $500 to $1,500. Builder's risk is quoted per project on contract value, so a three-week deck job is insured for weeks rather than a full year.
Your revenue band decides the quote, and projecting it honestly is where first-year applications go wrong; the deck and patio business plan guide covers what to include before you apply.
What each policy covers
Six policies show up on a typical deck contractor's quote. Each one answers a different failure.
What it pays for
- Commercial general liability
- Injury to other people and damage to property that is not yours
- Completed operations
- Claims after handover, including rot, poor flashing and frost heave
- Commercial property
- Yard, trailer, tools and stored materials
- Commercial auto
- Truck and trailer used for business
- Builder's risk
- The structure while it is going up
- Errors and omissions
- Design and estimating mistakes
What it does not cover
- Commercial general liability
- Your tools, your vehicles, your own defective work
- Completed operations
- The cost of redoing the defective work
- Commercial property
- The customer's house
- Commercial auto
- Errands in a personal vehicle
- Builder's risk
- Anything after you hand over the keys
- Errors and omissions
- Construction defects
Completed operations sits inside the CGL policy rather than beside it. A ledger board that pulls away from the rim joist two years after handover is a completed operations claim. That distinction decides who pays.
Which carriers write deck and patio contractors
The United States is the primary market here, so the table leads with US carriers. Route to a quote matters as much as price.
| Market | Provider | Route to a quote | Typically written for |
|---|---|---|---|
| US | Hiscox | Direct online | Solo operators and small crews |
| US | Next Insurance | Direct online | Small contractors needing a certificate that day |
| US | The Hartford | Independent agent | Firms bundling auto and property with liability |
| US | Travelers | Independent agent | Contractors buying higher limits or an umbrella |
| Canada | Intact | Broker | Firms wanting one carrier for property, auto and liability |
| Canada | Aviva Canada | Broker | Mid-size firms with subcontracted labor |
| Canada | Northbridge | Broker | Residential trades programs |
| Canada | Wawanesa | Broker | Smaller operators in BC and the Prairies |
| Canada | CNA Canada | Broker | Firms needing surety alongside liability |
Some carriers quote online in minutes. Others want an agent, a license number and a loss run before they bind. Whichever you approach, the guide to which licenses a deck and patio business needs first explains the order to get them and what each one unlocks.
What moves your premium
Payroll and subcontracted labor are the largest inputs. A firm that subs out 80% of its labor is underwritten differently from one carrying its own crew. Misclassifying a regular worker as a subcontractor creates a coverage gap and a tax problem, and the IRS test for independent contractor status is the one carriers apply.
Height is priced, not assumed. A ground-level patio and second-story deck framing land in different rating bands. OSHA's fall protection duty starts at 6 feet for work on walking surfaces with unprotected edges.
Claims history follows the business, not the owner. Three clean years is the largest input you control. Deductibles cut premium directly: moving from $1,000 to $5,000 changes the number more than shopping another carrier.
Example: the real cost of a failed ledger board or footing
Typical repair costs in the United States, before any claim is filed.
Real cost of a failed ledger board
- $2,500 to $6,000Rotted ledger board, replaced and reflashed on a single deck
- $3,000 to $8,000Settled or failed footing, re-poured and re-set
- $5,000 to $15,000Rotted joists and a partial rebuild
Ten years of CGL at $2,500 USD a year costs $25,000. One settled injury claim with $40,000 of defense can pass $140,000. The premium is a known number. The exposure is not.
If your bids do not load that premium into overhead, the comparison stays academic; the deck and patio pricing and profit guide covers how to load it line by line.
What insurers ask for at renewal
Missing paperwork delays a quote more often than it changes the price. Have these ready.
- Three years of loss runs.
- Current payroll, split between employees and subcontractors.
- The subcontractor list with certificates of insurance and expiry dates.
- Revenue split by type of work.
A certificate of insurance is not coverage until you confirm the additional insured wording and the expiry date. Their policy responds first. Yours responds if theirs does not.
Documented safety training also feeds the file. OSHA's fall protection training requirements call for documented training for employees exposed to fall hazards, which is the same record a carrier wants when it reviews your deck crews.
Gather these before the broker call.

Common questions
How much does insurance cost for a deck and patio business?
A US contractor under $500,000 in revenue typically pays $900 to $4,500 USD a year for CGL at a $1M to $2M limit. Canadian firms in the same band run $1,200 to $5,000 CAD at a $2M limit. Auto, tools and builder's risk sit on top.
Does general liability cover faulty workmanship?
It covers the damage faulty workmanship causes to someone else's property, such as a failed railing that injures a guest. It does not cover the cost of redoing your own defective work.
Do I need a certificate of insurance from every subcontractor?
Yes, with you named as additional insured and the expiry date confirmed. Their policy responds first, and a paid claim still lands on your loss history when they caused the damage.
How do I lower the premium without cutting coverage?
Raise the deductible, report payroll accurately, keep three clean years of loss runs, and bundle auto, property and liability with one carrier. Insurers also price the crew you carry, and the guide to hiring reliable staff for a deck and patio business covers what a stable roster does to your rate.
