Gutter Installation & Repair in Berthierville
In Berthierville, roof water does not fall onto open, newly built suburban lots. It falls on a dense, older town core along the St. Lawrence River, in a Lanaudière municipality within the D’Autray RCM whose territory is also connected to the Chaloupe and Bayonne rivers. The municipal council maintains both a flood-zone committee and a shoreline erosion committee: water is not a theoretical issue here. At the building level, however, everything comes down to three things: gutter slope, the number of downspouts, and where the water reaches the ground.
Downspout-to-Sewer Connection: The Rule Is Confirmed by the City
Let us be clear: the rules governing the connection of a gutter downspout to the sewer system vary from one municipality to another. We therefore will not publish a bylaw number, discharge distance, or fine amount for Berthierville here. What applies in a neighbouring municipality does not automatically apply here, and a contractor who quotes you a figure without verifying it puts you at risk rather than protecting you.
The only answer that carries weight is the City’s. Before having anything cut or connected, call the planning and environment department or public works and ask three questions: Is connecting a rainwater downspout to the sewer system permitted? Where must the water be discharged if disconnection is required? Is municipal authorization required? Write down the name of the person who answers.
Why this question is especially relevant here: Berthierville still has combined sewer systems in part of its older core—pipes in which rainwater and wastewater travel together—and is investing in separating them through its three-year capital program. Sending roof water somewhere other than the sanitary sewer system is therefore consistent with what the City is paying to do. That does not make it a legal requirement, but it is another reason to confirm your situation rather than assume.
An Old Town Core, Not a Suburban Subdivision
The census is clear about Berthierville: its housing stock includes a strong presence of rental units and plexes. Apartments in small buildings are the most common housing type, ahead of single-detached homes; together with duplexes, semi-detached homes, and row houses, multi-unit and attached housing predominates. This has three direct implications for gutter selection.
Roof area per downspout. A plex often has a long, continuous roof slope draining into very few outlets. What matters is not the number of units, but the number of square feet of roof feeding into the same gutter. When that ratio is high, overflow returns to the same corner during every storm and is mistakenly blamed on a clog. There are two solutions: add an outlet or increase the gutter size.
Where the water lands. When the lot is tight and the building is attached, downspout location matters as much as their number. A downspout discharging in front of a lower-unit door, onto stairs, or into a parking driveway creates an ice patch all winter long. It should be moved during installation, not afterward.
Building age and access. In an older housing stock, the fascia board has often already deteriorated: swollen, split, or soft in places. A gutter is only as secure as the material it is fastened to. The buildings may be low-rise, but they are close together: access may need to be from the rear or over a lower roof, and that must be confirmed before work begins. Finally, in a predominantly rental city, the decision-maker is often a landlord who does not live in the building: we document what we find so they can make a decision without having to go up themselves.

What We Check On Site
The Fascia
We check the fascia board before discussing gutters: soft wood will not hold any hanger. If it needs to be repaired, we say so beforehand.
The Slope
The gutter must slope continuously toward its outlets. Reverse slopes can be identified by standing-water marks and sediment left at the bottom.
The Outlets
Their number and location in relation to the roof area they serve. On long plex roof slopes, this is often the source of the problem.
Ground Clearance
Where the water falls and where it goes afterward. Discharging against the wall erodes the backfill and puts additional load on the drain. An extension does not push water away; it places it farther out. The ground slope is what carries it away.
