Eavestrough/gutters (the terms can be used interchangeably) are custom made on site using a roll-forming machine. Because your gutters are custom made on site you'll have a choice of size and a wide variety of colours.

Yes, because our gutters roll-formed on site they are continuous or seamless from corner to corner.

If your eavestroughs are leaking at the corners, show signs of corrosion, are loose and separating from fascia boards, or are undersized for the roof, it's probably time for replacement

If your existing downspouts are loose, showing signs of corrosion, leaking at seams or undersized, it's probably time for replacement

At minimum of once a year.
Conditions around the building such as vegetation, birds, and rodents will affect the required frequency.

The most common reason is debris clogging the gutter or outlets, however as buildings age they may settle which can affect the slope of the gutter installation.   Our Complete Trough Service Package can help resolve this issue.

If your eavetroughs are screwed on they can be re-sloped, however if corners need to be disturbed this may cause future leaks. If your eavestroughs are nailed on then it is not feasible to re-slope, however extra downpipes may be added at the areas which hold water.

5” gutters are adequate for most residential applications and are considered the industry standard.  For larger roofs a commercial grade 6” gutter system may be required. The size of gutter is the opening at the top of the gutters not the depth.

The rule of thumb is 40 ln. ft. of gutter or less per downspout, this will also depend on how many corners are in the gutters.
Keep in mind the amount of downspouts is not as important as the volume of water which the downpipes can discharge - ex: 3"x4" vs. 2"x3".
