Eavestrough Repair & Cleaning

Sagging runs are the most common call. A trough that dips between hangers holds standing water, which then freezes, which adds weight and drives the sag further — it is a self-worsening problem. The fix is re-hanging on continuous hidden hangers at proper spacing and re-setting the pitch by measurement. If the sag is because the fascia behind it has gone soft, the fascia gets addressed first, because there is no point screwing new hangers into failing wood.

Leaking corners and outlets are second. Sealant has a finite life, and in a climate cycling through freeze and thaw repeatedly each winter it ages faster than the manufacturer's rating suggests. A proper repair means cleaning the old sealant back to bare metal, not adding a new bead over a failed one, then resealing and where appropriate re-riveting.

Blocked downspouts are third and are the most under-diagnosed problem in this category. A trough that overflows at one end with no visible debris in it almost always has a plug at the outlet or in the vertical run. Clearing it and flow-testing is quick, and it resolves a symptom people often mistake for undersizing.

Ice damage is the fourth: crushed or deformed sections, torn end caps, hangers pulled clean out, and outlets split by expansion. Some of it repairs; some of it does not, and the deciding factor is whether the aluminum has been deformed past the point of holding a straight line and a seal.

And separated or pulling runs — trough that has come away from the fascia at one end — which is nearly always a fascia problem wearing an eavestrough costume.

Twice a year, spring and late fall. Both matter, but they matter for different reasons and the fall one is the one that prevents damage.

The spring clean deals with what winter left and what spring drops: accumulated grit and shingle granules, plus in this city an extraordinary quantity of poplar and cottonwood fluff and elm seed. That material packs down densely and reaches the downspouts, and clearing it going into the summer storm season is what keeps a system able to handle a July downpour.

The fall clean is the one that protects the house. Leaves that come down in October and sit wet in a trough do not blow out; they compact. When the first hard freeze arrives, that saturated mass becomes a solid block of ice running the length of the trough. It weighs several times what the system was designed to carry, it expands into every joint and hanger, and it is the single most common reason eavestrough tears away from fascia in Calgary.

Under spruce and pine, needle drop is continuous rather than seasonal, and a third clean partway through the season is worth it. Needles are the debris most likely to reach and plug a downspout, because they are small enough to pass a coarse guard and then mat at the outlet.

The practical cleaning routine is: clear the trough by hand, clear and flow-test every downspout — flow-testing is the step most often skipped and the one that finds actual blockages — check the pitch for standing water, inspect the hangers and seals, and check the fascia behind the trough for softness while you are up there. We do all five as one visit.

Three questions decide it.

First, what type of system is it? Sectional gutter — joined every ten feet — has a fundamentally limited life, because every joint fails eventually and they tend to fail around the same time. Repairing three joints on a system with eight of them is buying months. Seamless aluminum has only corners and outlets to fail, so repairing those is genuinely worth doing.

Second, is the fascia sound? Eavestrough hangs on fascia. If the fascia is rotten, no eavestrough repair will hold, and the real job is the fascia. This is by a wide margin the most common reason we recommend against a repair that a homeowner asked for.

Third, is the system correctly sized and pitched to begin with? Repairing a trough that overflows because it is too small, or because there is one downspout serving a fifty-foot run, restores it to a state that was never adequate. If the design is wrong, fixing the symptom is money spent to keep the problem.

Where all three answers are favourable — seamless system, sound fascia, correct sizing, localized failure — repair is clearly the right spend and we will do it. Where they are not, we will say so with photographs and let you decide with the facts in front of you.

Two events reliably generate eavestrough work in this region, and both are worth acting on quickly.

The first is the late-winter thaw. Every year, the first sustained melt reveals which systems carried ice through the winter and which were damaged by it — sections pulled away, hangers torn out, end caps split, and trough deformed where an ice mass sat. It is also when ice-dam damage inside the house becomes visible as staining along an exterior wall. Getting an inspection at that point catches the damage while the cause is still obvious.

The second is hail. Eavestroughs, downspouts, soffit and fascia are all soft metals, and dents in them are among the clearest corroborating evidence an adjuster uses to establish that a hail event of a given stone size actually occurred at your address. That means two things: your eavestroughs may well be part of an approved claim, and the damage to them is worth documenting even if you are mainly concerned about the roof.

Eavestrough damage is routinely left off hail claims because nobody inspected it. We inspect the trough, the downspouts, the fascia and the roof together and put all of it in one scope, which is materially easier for an adjuster to approve than separate submissions months apart.

For acreage properties, add the outbuildings. The shop and the detached garage take the same hail as the house and are almost always overlooked entirely.

The heaviest maintenance demand in this region is under Calgary's mature inner-city canopy — Elbow Park, Mount Royal, Britannia, Rideau Park, Renfrew, Bridgeland, Bowness, Hillhurst and Sunnyside — where elm and poplar cover produces a debris load that suburban homeowners would not believe.

The second is older suburban stock with original sectional gutter and unwrapped wood fascia, across Acadia, Willow Park, Haysboro, Thorncliffe, Ranchlands and Marlborough, where the trough and the fascia tend to reach the end together.

The third is acreage and foothills properties with conifer cover — Bragg Creek, Priddis, Millarville, Springbank, Bearspaw, Cochrane Lake, Water Valley, Sundre, and the Bow Valley around Canmore — where needle drop is relentless and the eaves are usually the hardest to reach safely.

We service all of it, plus Airdrie, Chestermere, Okotoks, High River, Langdon, Strathmore, Crossfield, Carstairs, Didsbury, Olds, Innisfail, Red Deer, Sylvan Lake, Beiseker, Three Hills, Drumheller, Nanton and Diamond Valley.

For rural properties we schedule the whole site in one visit — house, garage, shop and outbuildings — because sending a crew forty-five minutes out to clear one downspout is inefficient for everyone, and because the buildings nobody looks at are exactly where the small problems have been quietly getting larger.
