In my experience, sugar gliders are fairly resilient to disruptions in their surroundings and routines. Yes, it is easier for some than others based on their individual personality, but they usually adapt well sooner or later.
That being said, it sounds like a lot of reno in the room they're kept in, so my concern would be more to what they've been exposed to as far as paint fumes, dust from drilling, drywall, or any renovation that creates dust and debris. They have such small lungs, so something could have overwhelmed them. I strongly recommend taking them to the vet for a check up, better safe than sorry and sooner is better than latter if there are health issues stemming from renovation conditions.
Don't be so hard on yourself for your predicament, many of us (including me), have had situations arise where there would be disruptions to routines of out of cage play. I have had some extended ones due to some very huge changes in my living arrangements the past few years. I am now set up, schedule wise to offer 3X/week out of cage play, but two of those are fairly short (30min or less, usually less), while one on the weekend is about an hour, give or take depending on them. And, even still, because my living arrangement and space available, they have limitations on their out of cage play also. I'm continuously trying to work on solutions to make out of cage play more engaging as lately they seem to prefer their cage after a short period out. Many just go through stuff and changes, and we just have to do the best we can when we can.
