How big, and how high up?
Trough size and storeys. These two set the per-foot rate.
Trough size
Storeys tells us how much ladder and scaffold time the job takes - it's the single biggest thing after the length itself.
Step 4 of 8
Pick the material.
Three lines we install every week. Colour is free; only the gauge moves the price.

Aluminum thickness
Colour - doesn't change the price

What this tool is
Plan your eavestrough installation from your phone or computer. Enter your address, trace your roofline, choose the size, material and extras, and see your measurements and calculated price at our published 2026 GTA rates. When your plan looks right, send your booking request to LF Builders.

The fine print that matters
Your price is calculated from your roof measurements, selected options and our published rates; it cannot be manually overridden. Aerial measurements are a starting point. Before work begins, we confirm the measurements, fascia condition, drainage and access on site. Sending this form is a booking request, not a confirmed installation date. No payment is taken here, and you approve the final scope before work starts.
