Can anyone point me towards a good source of information on what the options are with adjoining extensions / anything I should be aware of, so I can at least provisionally agree something with my neighbour? But even with a flat roof, I've briefly looked into the recessed / box guttering options and they seem fraught with problems. Crawl Space Brothers is committed to providing top-quality underground gutter downspout extension installations, safeguarding your home from potential water-related issues. The architect doing my plans has been quite unhelpful and just says that level of detail won't be specified until the building control stage.

Protecting Landscaping: Proper water management can reduce soil erosion around your home, preserving your lawn, garden, and other landscape features.As commonly described, a downspout is an extended pipe or flow pattern that allows excess water to run off away from your home for the purpose of protecting the underlying foundation of the house. We’ll install a 4-inch drainage pipe within the trench, cutting the base of the downspouts approximately 8 inches above the ground for optimal drainage. If you opt for our preferred seamless gutter system, which includes a downspout outlet, and pair it alongside a downspout extension, there is a slim chance of any leaks emerging.

Having some kind of outlet or way of getting into the pipe without digging it up can help with future maintenance and replacement costs later down the road.Aiming for a distance of 10 feet can ensure rainwater is sufficiently diverted away from your home’s foundation.

Most want crates rather than traditional hardcore as this provides a lot more storage when rain is heavy and/or ground not very permeable.So if he were to build an identical extension, we'd end up with a 'valley' effect which I'd imagine is a drainage nightmare. For medium to larger-sized blockages, especially ones in your downspout outlet, a drum auger is used. Rain barrels are eco-friendly systems installed at the end of a downspout extension to collect rainwater. If you both end up extending then a shared party wall on the boundary is a better plan than two separate walls with a tiny gap between.
