Single car garage. The bedroom upstairs is above the garage and noticeably colder than the rest of the house in winter and very hot in summer. There's no climate control in the garage and its not underground.The ceiling is finished so I can't see what kind of insulation we have between the garage and the floors above.
Any ideas about insulating garage ?
How much would it cost approximately ?
Any contacts of contractors in central nj area for this kind of work?
You may not have any insulation, typical builder shortcut. Only way to find out is punch a hole and see.
We had a 2 car garage in Sussex County that was sheet rocked but not insulated. We had a company come in that punched 2" holes in the walls between the studs and blew the insulation in thru the holes. The holes were punched maybe 12" up from the floor. The company then patched the holes in the walls when they were done blowing in. They were able to access the ceiling thru an existing hatch. If you don't have a ceiling hatch they can blow in anyway. Patches were a little rough but I sanded them down once they dried and then painted. I also bought foam insulation and glued it to the inside of the garage doors. Worked out real well, made a huge difference.
The price would be based on your square footage. We paid maybe $900, garage was 24x24, had 'em put 12" in the ceiling and 6" in the walls. Took 2 men the better part of a day to complete the work, they were very thorough and worked neat. It was money well spent as I spent a lot of time in the garage on my old car hobby.
as for contractor in your area, do a search for "blown in insulation contractors Central NJ". As always, check their credentials before you commit. My contractor came, measured, gave his estimate and didn't ask for any money up front, paid when the job was done.
If you are serious about insulating or putting better insulation in the ceiling of the garage, cut a hole in the ceiling and see what R-value insulation you have or if you have any insulation at all. The ceiling will have to be taken down either way. Another cost factor to figure in.
If you choose spray foam, we found that there is a minimum cost for doing so. Spray foam is also much more expensive than fiberglass insulation.
If you go through the trouble of insulating the ceiling or re-insulating it, make sure your garage door is insulated. If it's not the heat will escape through the door.
very helpful responses . thnx a lot for taking time to respond.
the problem is we cannot use our bedroom at all . so one room is useless in winter and peak summer.
hence we are serious about insulating garage.
we got to know higher - r value insulation matters.
spray foam is great idea. we didnt know this is even possible.
another point is after punching hole in garage ceiling , what if we discover a gap of say 8 to 12 inches between bedroom floor and garage ceiling ? can fibre glass or spray foam cover such huge gaps ?

Fiberglass insulation comes in different thicknesses - definitely up to 12 inches.
We have this exact same problem. Many builders don't insulate the garage (ceiling and/or walls) as a shortcut and to save $ (idiotic imo). I had a guy come in yesterday and it's a pretty easy fix to do what scrantonscrambler did. We have vinyl siding, what they do is take off one or 2 panels from the outside, drill holes and blast in blow-in insulation (fiberglass or cellulose) in the 6-8" space between the garage ceiling and upstairs floorboards. Cellulose is made out of chopped up recycled newspaper, is efficient and treated to be very fire, mold and pest resistant. They then plug the holes w/ a wood plug that fits perfectly, put back the vinyl and you'd have no idea insulation was put in. This can also be done from inside the garage through holes in the ceiling, but it's easier from the outside.
Garage will still be cold, but it should help the rooms above remain warm.
