Gutters in Blainville | Bylaw 1450 Compliant
In Blainville, water leaving a roof does not simply disappear: it is discharged onto the ground, a few feet from the foundation, and the property then determines what happens next. Every rainfall deposits that volume in the same place, storm after storm—which is why it matters to know exactly where your downspout discharges water today. That is precisely the approach taken by the municipal bylaw that applies in the city. Gouttières et Revêtements Synergy holds RBQ licence 5723-4940-01 and serves Blainville.
Bylaw 1450, Article 53: A Requirement That Isn’t Measured With a Tape
Blainville applies Bylaw 1450. Article 53 addresses roof runoff discharged through gutters and downspouts. The key point is this: Blainville does not impose a numerical distance requirement. The requirement under Article 53 is qualitative, not numerical—the water must be discharged at the surface.
Some neighbouring municipalities specify a distance in their own bylaws; that is not the case here, and a number borrowed from another city would have no standing in Blainville. The criterion is not a measurement, but a method of discharge. In plain language, “discharged at the surface” means the downspout releases water onto the ground, in the open, where it can be seen flowing and where its path can be checked—instead of making it disappear into an underground pipe.
We do not add anything to the bylaw: no amount, no deadline and no minimum distance, because none appears in the article. Before work begins, confirm how it applies to your address with the City of Blainville; the text is published on the municipal website.
What Changes From One House to the Next
We do not make decisions remotely: gutter size, number of downspouts, access and working height must be assessed one elevation at a time. Rainfall does not flow the same way on a detached single-family home as it does on a building where three roof slopes converge at the same corner—and that kind of difference is visible on site, not on a map.
Channel Size: 5 or 6 Inches
Gutter size is selected based on the square footage of roof draining toward the section in question and on the roof slope. A large roof slope draining into one gutter requires sufficient capacity; otherwise, water spills over the edge.
Number and Position of Downspouts
The more square footage each downspout handles, the fuller the gutter must remain to drain properly. The discharge location matters just as much: because Article 53 requires surface discharge, there must be a place where water can spread out without returning toward the foundation or crossing a driveway.
Access and Height
A two-storey home, a recessed wall or a low-slope roof does not require the same access equipment. We assess this before providing a price, not after taking out the ladder.
Leaves, Ice and the Attic
An unobstructed elevation and a wall lined with mature trees are not handled the same way. A poorly ventilated attic, meanwhile, creates ice along the roof edge.

What We Check On Site
| Point Checked | What We Look At |
|---|---|
| Fascia | The wood behind the gutter must be able to hold the fasteners. Softened by previous overflow, it holds nothing—and that becomes visible when the old gutter is removed, not from the ground. |
| Slope | A consistent slope toward each outlet, with no low spots that hold water between rainfalls. |
| Outlets | The number of outlets in relation to the square footage being drained, their location relative to valleys and inside corners, and the condition of the bottom elbow. |
| Ground clearance | Where water is actually discharged at the surface, and whether the grade carries it somewhere other than the base of the wall. Fill that slopes toward the house sends everything back to the foundation, regardless of the extension. |
| Soffit | Ventilation and panel condition: a warm attic creates the ice that loads the roof edge. |
