7 Inch Commercial GutterBrush Gutter Guard
7 Inch Commercial GutterBrush Gutter Guard
GutterBrush Canada · 7″ Commercial
Canada's commercial gutters swallow enormous amounts of debris — and almost no gutter guard on the market is made to fit them. The 7 Inch Commercial GutterBrush is one of the only ones that does: a heavy-duty brush sized for large 7″ (17.8 cm) commercial-grade gutters that installs with no tools, no nails, no cutting and no drilling.

Why the 7 Inch GutterBrush Works on Commercial Buildings
- Sized for commercial box gutters: a 6.5″ (16.5 cm) brush that fills a 7″ trough.
- No trades or lift-time spent fastening: sections drop in by hand — no screws, clips or roof penetrations.
- Keeps big gutters flowing: water passes straight through the bristles.
- Cuts maintenance call-outs: less debris reaching the bottom of the gutter means fewer cleanouts.
- Lift out to service — no panels to unscrew.
- Deters birds and pests from nesting in open gutters.
Which Canadian Commercial Gutters the 7 Inch GutterBrush Fits
- 7″ (17.8 cm) commercial box-style gutters on shops, barns and warehouses
- Large K-style and half-round gutters — aluminum, copper, PVC, wood or steel
- Any roof type — asphalt shingle, cedar shake, slate, tile, rubber or metal
Quick size check: measure straight across the top opening. 7″ (17.8 cm) = this product. 8″ gutters take the 8 Inch Commercial; 6″ take the 6 Inch.
How Much 7 Inch GutterBrush Do I Need?
- Measure each gutter run in feet (or metres × 3.28).
- Add the runs together.
- Round up: up to 18 ft = one 18 ft box; 19–36 ft = one 36 ft box; longer, combine boxes — or send us the total for volume pricing.
Example: a 60 × 40 ft shop with gutters on both long sides = 120 ft → three 36 ft kits + one 18 ft kit, or ask us for a volume quote.
Commercial GutterBrush vs Ice Dams Over Entrances
A clogged commercial gutter holds standing water that freezes solid, feeding ice dams and icicles over entrances and loading areas. GutterBrush keeps the trough open so meltwater can drain, and its black UV-treated bristles absorb heat on sunny days to help ice along the gutter line melt sooner.

7 Inch Commercial GutterBrush FAQs
Do you offer volume pricing for commercial jobs?
Yes. Send your gutter size and total linear footage through our contact page and we'll quote it, usually within one business day.
How do I tell a 7 inch from an 8 inch commercial gutter?
Measure straight across the top opening: 7″ (17.8 cm) takes this model, 8″ (20.3 cm) takes the 8 Inch. Send a photo with a tape across the top if in doubt.
Does it need a contractor to install?
No — there are no fasteners. Anyone who can safely access the gutter can drop the sections in.
Does GutterBrush stop pine needles?
It stops leaves and larger debris well. Needles and seeds can catch in the top of the brush but generally stay up there to dry and blow off; under heavy pines, plan on an occasional shake-out.
Is GutterBrush maintenance-free?
No gutter guard is. When it needs attention, lift sections out, shake or hose them off, and set them back — far faster than mucking out an open gutter.
Where does my order ship from — will I pay duties?
Orders ship from our stock in Paris, Ontario, priced in Canadian dollars. No duties, no brokerage fees.
