Gutter Cleaning Mascouche
Mascouche: 3,500 litres of water per downpour. Where does it go?
Gutters are often treated as a detail. The numbers say otherwise. Here, in a few simple calculations, is why a clogged downspout in Mascouche can get expensive.
- Complete maintenance: roof blown off, gutters emptied by hand, downspouts cleared
- Included at no charge: fasteners, up to 2 joints and 10 hangers
- Proof: before/after photos and report
- Quote: online, no visit
The calculation nobody does
Take a typical two-storey house in Mascouche, with about 140 m² (1,500 sq. ft) of roof, and a good summer downpour of 25 mm.
140 m² × 0.025 m = 3.5 m³, or about 3,500 litres of water in a few hours.
With 4 downspouts, that's about 875 litres per downspout. If just one is clogged, those 875 litres overflow in the same spot, often at the corner of the house, right above the foundation.
150 cm: the bylaw's number
In Mascouche, the connections bylaw requires roof water to be released on the surface at least 150 cm from the building, avoiding seepage toward the underground drain. The City even recommends aiming for 1.5 to 3 metres.
A downspout that ends with a simple elbow at the foot of the wall doesn't meet that distance. A 1.2 to 1.5 m extension does.
What maintenance costs, compared with what it prevents
- Complete maintenance: a fixed price, known in advance thanks to the online quote.
- Included at no charge: up to 10 screwed-in hangers and 2 sealant joints. Small repairs are often what prevents big ones.
- What you avoid: rotten fascia, foundation cracks that let water in, a wet basement. Each of these costs far more than a maintenance visit.
With Alu-Rex gutter guards, maintenance goes from twice a year to once every 2 to 3 years. See the numbers.
