Injection Foam Insulation

There was a recent discussion about Heavy Drafts Coming Thru Baseboards and outlets but the thread is closed. I have a similar situation where there’s no insulation on my exterior walls.
I’ve been considering Injection Foam Insulation, where they drill small holes in-between every wall stud, and spray closed cell foam thru each hole. I was quoted $2300 to do the front & rear walls on 2 floors. (4 walls total). The foam might not cover every nook and cranny, especially if there’s alot of debris or blockages inside the walls, but it seems like a cost effective option, and significantly less invasive, even with all the holes to patch afterwards. I’m concerned that electrical outlet connections inside the walls could be damaged during the injection process. Has anyone had experience with or opinions about Injection Foam Insulation?

so i don’t have experience with this type of insulation installation but I would say that my understanding of one of the limitations is that it can make future changes/repairs very difficult because of the way it encapsulates everything inside the wall. Assuming the installation doesn’t do damage to your electrical (I’m guessing it probably wouldn’t) should you want to relocate services or need to do repairs to anything inside the wall in the future you would have to chop out the insulation to get to the services. Are your walls brick? Perhaps they could use some repointing instead…
