THE SHORT ANSWER
Estimate gutter replacement with separate measurements for horizontal runs and downspouts. Include outlets, corners, removal and access, and state whether fascia repairs or underground drainage connections are part of the job.
This guide follows a fictional 140 linear ft. gutter replacement in Moncton, New Brunswick. The linked gutter replacement PDF example shows the scope and 7 separate costs in Canadian dollars. Treat it as a worked document, then use measurements, supplier quotes and labour inputs from your own project.
1. Measure runs and vertical drops separately
Gutter length does not tell you the downspout quantity. Record each run, outlet and drop. Confirm whether the quoted material matches the customer’s selection and whether special corners or connections are needed.
2. Identify the existing-condition assumption
New gutters depend on the condition of the supporting surface. This example assumes suitable fascia. If repairs are visible or likely, inspect and price them separately rather than allowing a replacement gutter line to imply carpentry work.
3. Define the discharge scope
State where the downspout work ends. An above-ground extension and a connection to an underground system are different tasks. Record what existing drainage is being reused without claiming this sample sizes or designs a drainage system.
4. Include removal and handling
Removing the old system, collecting debris and protecting nearby areas all require effort. Explain disposal and access requirements. Keep optional accessories separate until the customer decides whether to include them.
Review the Canadian project address
For the 140 linear ft. gutter replacement in Moncton, New Brunswick, the example uses the measured trade units shown in its PDF. Residential jobs may mix square feet, linear feet, counts and supplier units; keep each line’s measurement basis visible. Check exposure, access, drainage and any concealed water damage at the property. Confirm the selected product and local approval requirements before setting the final scope. The figures are fictional CAD inputs, not a local price survey.
Describe which products the customer supplies and which the contractor supplies. State how any site condition outside the visible scope will be assessed and priced. Do not copy an allowance from another city or assume a sample’s tax entry establishes the treatment for this client.
Work through the gutter replacement quantities
The matching PDF lets the client check each extension of quantity and unit rate. For this example, two useful checks are:
- Existing gutter removal: 140 linear ft. × C$1.75 = C$245.00.
- Gutter material allowance: 140 linear ft. × C$5.55 = C$777.00.
Adding all 7 lines gives a C$2,315.20 illustrative subtotal. The PDF records 0% tax and C$2,315.20 as its total, before any markup. These are chosen sample inputs, not prices observed in Moncton, New Brunswick. The measurement basis matters as much as the rate: a material purchase allowance may be larger than the installed area, while a fixture count is not interchangeable with hours of labour.
Check the scope before sending
- Count runs, corners, outlets and downspouts.
- Inspect the fascia assumption.
- State where discharge work ends.
- Separate optional accessories and drainage connections.
Outside the illustrated scope: No fascia replacement, multi-storey access, underground drainage, gutter guards or drainage-system design.
Check the business and client names, property location, dates, quantities, unit rates and notes. Confirm tax, markup and any required approvals for the actual job. If selections or site conditions are unresolved, label the line as an allowance and explain how it will be updated.
Common questions
Should downspouts be included in gutter length?
Measure and label them separately. Horizontal gutter runs and vertical downspouts have different quantities and may have different material and labour rates.
Are gutter guards included automatically?
No. List them as included work or a separate option, with the selected product and quantity.
