Hello everyone,
we are now homeowners and need to enlarge the connection of two rainwater downpipes from a 70mm (3 inches) diameter to a 100mm (4 inches) diameter where they enter the ground.
Why? Because everything else (including the orange underground pipes) is 100mm, and for some unknown reason, the roofer installed a 70mm pipe in between during the previous owners’ time. The result: water backs up at the edge of the house because it can’t flow properly through the narrowing.
I have never done this before but want to consider if we can do it ourselves. 200 (two hundred) for materials and installation (if we expose the pipes) seems a bit high to me—maybe it’s normal?
Tomorrow we will also call the above-mentioned roofer again—after all, from our point of view, he messed it up.
Either way: what should we keep in mind? How do you connect two pipes so that the joint really, really holds and is watertight?
Best regards,
Trilla

For that amount, I wouldn’t even hesitate. When building a house, you’re usually dealing with costs in the four-figure range—and it shouldn’t be different for renovations either.
An hour of skilled labor usually costs around €50-80 gross (about $55-90), depending on the trade... it probably doesn’t get any cheaper than that.
It also depends on the type of downpipe. There are ones made of metal and others made of plastic. Some metal ones are soldered, which means a layperson may not be able to replace them without the proper equipment.
However, there are also galvanized pipes, which are often designed to be connected by slipping them together, allowing you to do the work yourself.
I recently bought a complete set for my carport consisting of gutters and downpipes, each 4 meters (13 feet) long, for under 100 € on eBay.
