I'm trying to install a basement dryer vent and have a logistical
problem that I'm hoping people could help me with.

The house I purchased has the dryer/washer in the basement laundry
room. The basement is completely below ground level. The previous
owners never vented the dryer outside and now I know why. Instead,
they just vented it into the laundry room and placed a stocking over
the end of the dryer hose to catch the lint.

A slate patio butts up right against the house. I measured exactly
where the vent opening would come outside the house if I were to drill
a 4 inch round hole and it would come out an inch or less above the
slate patio - so this is not a viable solution. I should also mention
that there is a window well on the cinder block wall directly behind
the dryer but I do not want to vent out the window into the well as
this would likely over time fill the well walls (more cinder blocks)
with lint and look pretty crappy.

My other alternative is to run an extended length (maybe 15 feet) of 4"
round dryer vent parallel along the floor/wall past the end of the
patio and then out through the wall where there might be perhaps a foot
of clearance off the ground (still not as much as I would like but
better than no clearance).

Are there any other solutions I might investigate? I can't run a
smaller diameter vent because of back pressure issues and such.

I am looking for any/all suggestions/comments.

Thanks!

Then run a rectangular duct vent. As long as the cross sectional area of
the duct and vent is as big or larger than the equivelent dryer hose, it
will be fine. Ample options in transitioning from round to rectangular
along the way.

For a cap, look at parts used to finish off bathroom and or kitchen range
vents. I know they have rectangular caps for kitchen vent hoods.

For 3"duct area= 7 square inches so a 2x6" duct with 12 square inch area
should be fine for even a longer run.
