It has been a couple of months since i did the foam it green install. i used it for the crawl space of my retirement home here in warwick rhode island. the house is a hundred and ten years old, and on the water. about a week ago i retired from my job in sunny warm california and moved here to warwick. i did the prep and foam spraying over the last six months when i came to visit.

as you can see from the pictures when i bought the house it had water logged fiberglass bats under the house. hurricane sandy supplied the water. totally the wrong insulation to use in this location and application. as you can see from the pictures the fiberglass was a mess. i don't know if you have ever pulled wet fiberglass insulation from under a crawl space, but it is a s#@t job. i used a four tine garden rake to pull it out and pile it next to the house. it took a very long day to remove and bag it. it was miserable crawling around under there removing the old stuff. i cannot emphasize enough that fiberglass is totally the wrong material. check the pictures to see the debris pile.

to prepare the crawl space i took a stiff brush and brushed off everything under the house. beams, sub floor, pillars, and spiders. the spiders were not happy. it took about three hours to clean off everything.

the next day i did the foam. it took almost seven hours to do the job. that may seem like a long time, but the crawl space is about a foot and a half high at it highest point and of course has a dirt floor. lots of plumbing to work around. not much room to move around and not much light. i had a couple of halogen lights i needed to keep moving with me. i had three fifteen foot hose kits and one thirty foot hose kit. the thirty foot kit was a huge help to get to the center of the space. the tanks would not fit under the house so i had them on a cart that i moved around out side of the crawl space and led the hoses underneath.

for safety gear i used a full face respirator with replaceable covers for the lens. an absolute necessity when working in a laying position and spraying above myself. instead of the supplied tyvek suit i used a three piece rain suit with a hood. the ground and rocks under the house would have torn through the tyvek suit. the rain suit worked well. i also used a few pair of leather gloves. pulling myself around under the house would have shredded the plastic gloves.

i think my results are excellent. the green color really helps when spraying and when the tanks get empty. at the end of the tanks the color changed to a darker green/blue. that made it very easy to tell when it was time to hook up the next kit. a big help as the tanks were out of the crawl space and i was not able to monitor them without climbing out of the space.

i do not feel any drafts at all through the floor. it was in the twenties last night and windy so if there was a leak i think i would have felt it.

i followed the directions on your site and i believe i have excellent results. the crawl space is about four hundred square feet. i ordered one of your twelve hundred sq ft kits and one of the six hundred sq ft kits. i have at least four inches under the house everywhere. probably closer to six inches as the beams under the house kinda big (6 x 12), and i did not spray them. there were many gaps and holes from who knows what in the floor that the foam filled them beautifully.

i would definitely recommend the foam to anyone. in the future i would like to tear out all of the wallboard and ceilings and spray foam every wall and ceiling surface of the house. a big job, but i have time and i can do them standing up!

the whole time i was spraying i was wondering how much i would have had to pay someone to tear out the old fiberglass insulation, clean under the house, and take a full day to spray the foam. i would never be able to talk myself into doing this for any amount of money if it wasn't my house. it was not the most enjoyable of jobs, but i know it was done well because i was under there doing it.

thank you all for a very easy to use product.

did i mention pulling out wet fiberglass insulation is the worst @%*&ing job in the world? you don't even want to smell it.

the dirty old man in the picture? yeah that is me after pulling out the old fiberglass insulation. spend a day doing that and you will not be smiling either.
