November 27, 20241 yr Hi again, folks Firstly, apologies if this is already well trodden paths. I'm sure something as generic as this probably gets resurrected more times than a boybands career! 😁 However, if not then please read on... We'd be looking to have our home's cavity walls insulated, and after your guys high level advice/experiences. I have some basic questions, but please feel free to add anything you feel of value 👍 The house walls are outer brick/inner block. I'm not sure of the cavity gap/condition, but for the purposes of this convo: lets assume it's suitable for any approach.... My questions are: What is your preferred insulation material(s)? - i've heard good things about EPS and foam (tho both have pros and cons). I'm leaning towards EPS (due to cost), but happy to find out more What to look for with companies providing the service - plenty have reasonable reviews on Checkatrade/etc, but some are likely better than others. So are there any accreditations/memberships to really look out for? Quoting for cost - dumb question (my specialty 🤪), but costs i've read online are by m2. I assume the reputable companies factor in window/doors into their quote, and don't just crudely estimate based on rough wall dimension? (i'm not sure if this is a good yardstick to measure if estimates are realistic tho? 🤔) Guarantees - am i right in thinking all work guarantees (some i've seen are 25 yrs) should be insurance backed? GBIS - does anyone know if GBIS companies are any better/worse than anyone else? I've occasionally seen online non-funded jobs (eg: private) are sometimes completed badly Anything else - eg: building regs signoff, that may be required? Many thanks as always for your sage suggestions Shadow
