Do you feel cold  in your bedroom room?  Do you feel drafts while sitting on your couch?  Are your walls cold to the touch?

Then your home needs wall insulation

Side wall insulation is not only good for reducing your energy bills, but it will also make you more comfortable in your home. Side wall insulation is great for sound reduction as well as eliminating drafts.

The Process is Simple


Remove siding and drill hole

The siding is removed and a hole is drilled.  All types of siding can be removed, vinyl, aluminum, shingles clapboards and even asbestos! The hole is then plumbogged and felt with wires to find any hidden block or brace that could occur in the houses structure. The worker then measures to the next block or stud and makes an appropriate hole.

The insulation is blown in at such high pressure that it is firmly packed within the wall cavity. Insulation can be blown in using the multiple hole technique or the fill tube method.

Cover with water seal

A foam plug is placed in the hole. Then, the hole is then covered with a piece of felt paper for a weather seal. This prevents any water from entering the wall cavity.

Put original siding back

Once sealed the original siding can put back. Galvanized finish nails are used for shingles and clapboards which provide great holding power without tarnishing. JM of New Bedford can reinsulate through almost every type of siding (I.E. Brick cannot be done from the outside)

The wall is now water tight and fully insulated

Houses may also be insulated from the inside, JM of New Bedford will patch the hole with a foam plug and put a coat of spackle over the hole.
