Tree ID & Maintance Questions

Im not sure what these trees are. Their so tall now they are almost not noticable from the street. Should I trim them or leave them.

 

Radermachera sinica. I'd remove it, as it is so close to the foundations.

 

Thanks for the speedy reply. This site is great. Now I gotta convince the wife to let me remove them.

 

Ask her if she prefers the alternative - a $50,000 bill for repairs to root-damaged foundations (oh, and also moving out for 6 weeks while the workmen are in!) ;-)
