Eavestrough, gutter guards & fascia in Thornbury

The mature maples along the older Thornbury streets are the reason this town has more guarded eavestrough than anywhere else we work. Leaves are the easy part. Maple keys are the problem, because they arrive in enormous numbers in late spring, they are small enough to sit in a mesh opening rather than blowing off it, and they germinate in the silt at the bottom of an unguarded trough. A trough with seedlings growing out of it has been full for at least a year.

Micro-mesh is the guard type that handles keys and needles together, and it lets meltwater through rather than icing shut. The cheap snap-in screens do the opposite: they trap the keys on top, ice over in a freeze-thaw week, and collapse into the trough under the weight. We do not install those, and pulling them out is a regular job here.

Guards reduce clearing. They do not end it. Fine debris still builds slowly on top of the mesh, and once a year somebody has to brush it off, which is a great deal less work than digging out a full trough twice a year. Anyone who tells you a guard is permanent is selling one.

The homes near the harbour were built before hidden hangers existed. The trough was hung on spikes driven through the front of the trough into the rafter tail, and every one of those spikes is a hole. When we take an old run off a century home the sub-fascia behind it usually has decades of holes, several generations of them, and often a soft strip along the top edge where water has been tracking behind the trough.

A hidden hanger screws into that same wood, so the quote has to deal with the wood first. On a good day it is a strip of sub-fascia along one elevation. On a worse one the rafter tails themselves have gone at the ends and get sistered before anything is hung. Either way it belongs in the quote before it goes in a price, because it is the part that decides whether the job lasts.

There is also an appearance question on the heritage-fronted streets. Modern K-style trough on a century home is not automatically wrong, but proportion matters, and so does the colour against original trim. Where a house needs it we will talk about profile rather than defaulting to whatever is on the truck.

The newer half of Thornbury has no maples worth worrying about and a completely different failure. These are large modern roofs with long unbroken eaves, wide overhangs and, very often, a downspout count decided by how the elevation looked to the builder rather than by how much water the run carries.

The symptom is a corner that overflows in a heavy rain or during the March melt, on a trough that is only a few years old and perfectly sound. The owner assumes the trough is undersized. Usually it is not: the water simply cannot reach the only exit fast enough, and it goes over the end before it gets there.

The fix is drops in the right places and enough of them, plus extensions that carry the discharge past the backfill. New subdivisions settle for years after they are built, and water landing next to a foundation on disturbed ground is how a five-year-old house develops a damp corner.
