I think the best way to "cover it" is to leave it alone - use appropriate landscaping as an attraction away from the vent (principle of distraction). With attractive landscaping at the people level, no one is going to notice the vent high up on the second floor (except you). Right now your landscaping isn't really visible. Try the landscape forum here on houzz for ideas.

For reference, these are the exterior colors.

Not a Pro.

If you are allowed to paint it the same color as the siding.....I would do it :-)

@Denita Thanks for the input. Is there anything I can do from landscaping's perspective to fully cover it? I worry about the potential long term damage a tree would cause if it's right up against the house. The "garden" area isn't that wide. Is there anything I can hang off of the eave?

I'm not the right resource to ask for specific plants or even a landscape design - but there are some awesome posters in the landscape forum that know these things. I know when a particular landscape doesn't work well because I'm a Realtor and curb appeal is critical in my business. However, I'm in South Fl - so I have no idea of the plants that work in your area and I don't want to mislead you at all.

I do know if you start to put a tree in to cover up something on the second floor a natural response by normal people is to follow the tree upwards with your eyes and you have then actually made the vent more visible rather than less visble. That's why I said to change/beef up your landscaping. If I were there I would be putting a tree off of your far right corner and adding in colorful swaths of flowers in the planting beds.

@ njmomma The builder did say I could paint it! I also have some leftover paint color. I wasn't sure if it would make a difference and I wan't sure how to make the paint last since hot air is going to be coming out of it.. But now that I think about it, I should definitely try painting it first! Thank you!

I wonder if a replacement from a ships chandler would work? It could be painted or if brass might be decorative.

A potted plant place in front of the vent vs ground planted?

@User - the vent is on the second floor to the right of the far left window.

OK, thanks re location..

Paint to hide or replace with brass. Either hide it, or make it a feature.

It now Looks like a pimple or blemish....either hide it or make it a beauty mark.

I think once you paint it you will be surprised how little you notice it.

Doesn't have to be heat-proof paint. Hi-eff furnaces recover so much heat the exhaust is barely warm to touch, which is why the exhaust pies are plastic.

You will need to put a coat of an oil based primer before applying any latex paint. Kilz primer should work well.

I am not familiar with this type of termination kit but wonder if one of the products from HideAVent could be adapted to conceal it to your satisfaction without compromising the needed airflow. Worth checking out if you haven’t yet. Might be adaptable or if not, may inspire you to a different work around.

I agree that painting to match siding color would be an excellent (and relatively cheap) first strategy .
