Insulation question/ recommendations?

Hi all,

I have a house with a garage and there is both a bathroom and an office that share a wall with the garage. These rooms are consistently much colder than the rest of the house. I'm thinking there may be an issue with insulation between the two spaces and/or perhaps the ceiling. (I believe the office may also share the ceiling crawlspace with the garage).

Anyone every deal with this? Or anyone use a contractor/person to help with such an issue?

Thanks!

What do those 2 rooms have for heat ?

Oliver,yes, if they share a ceiling, that could be a cause. Make sure there is adequate insulation above and even consider adding more. It's a fairly easy and straightforward job. Our master bedroom is above the garage and was considerably colder than the rest of the house. I added another layer of R-12 and it solved the problem. In essence, you're 'capping' the heat and preventing it from escaping. We're saving 25-30% on heating and cooling to boot.

I'm not sure if they will come and do an assessment or if they are just the end providers, but we had Eastern Insulation come do half our house with spray foam when we renovated that side... They also did all the interior insulation (for sound dampening) and fire stopping. Very competitive pricing, they came when they said they would and they are done when they said they would be. There was some miscommunication (somewhere between us, our GC and them) and the guys on site called it in and had more material delivered while they were working so as to still complete the job on time... Pretty impressive compared to most of the other subs we dealt with.

Remove the drywall and insulation in the garage. Then get some spray foam done.

I have the same with a laundry room and a sitting room off the kitchen that are always very cold in the winter. Both share a wall with the garage. Would a general contractor come in to remove drywall and spray foam the area? Does anyone know?

Janet - Depending on the area you may not even need spray foam. Overhead insulation can often be just some self-installed fiberglass. Even in the case of foam, you wouldn't necessarily need a general contractor either. The specialist would probably do it all for you, and in the case of foam my understanding is you often don't even remove the drywall. All depends on the exact type of insulation.


Correct GC, they don't need to remove the drywall. They can cut small holes and just spray it in.
