How do you take those Pixel Ahh Gunfights on windows as an Attacker

As said i really have a problem with those type of gunfights because i find myself with no utility i could use to push in because i play a lot of ace.

Also i cant really shaiko peek, ive tried it but i am just not at that skill level yet.

And for some maps its just becoming unbearable because if u dont contest those windows u cant get control of important rooms next to site like green hallway on kanal or bedroom/bathroom on villa

And it just annoys me because defenders can just setup the pixel angle as soon as they hear the barricade, meanhwile u have to drone them first and blabla u get the deal.

Should you just ignore them and take a other route or is there a way i can deal with this?
