Hi everyone. i’m super new to this forum pls forgive if this topic is under wrong category recently bought this house and when we were about to engage contractors to change our living room windows we bumped into a huge roadblock. I’ve attached pics of my living room window basically we are unable to change the window or window grills because its attached to the concrete. Apparently we need to engage with PE (precision engineering) to even remove the grills which will cost more than $3k. we went to check with 2 of our neighbours below to see whether their window grills looked like ours. I’ve Attached my neighbours windows and its not the same as ours (the below part) is there any other alternatives for this? How can we refurbish the windows and grills if we are unable to change?
