3rd floor two large crawl spaces completely uninsulated in 1890s house. Need wall and floor coverage. Perhaps also basement ceiling.

We would like to spray insulate the rim joist throughout our basement (which is unfinished).
Vicinity of BONANZA ST in Lawrence
1190 sq ft house. In winter pipes in attic freeze and heat runs often. In summer cold water from attic pipes is very warm and AC seems to run often. Don't think there's enough blown-in insulation. Just need a quote for that square footage for labor/materials

I was hoping to get an estimate on insulating our house, particularly the attic.

Good Energy said our energy bills seem high and we should have the depth of our insulation checked.

Roof of older house needs foam insulation. Footprint is 31'x24' and roof pitch is about 6.5/12 making the 2x4 roof rafters about 13 1/2'. Looking for estimate for open cell vs closed cell foam. Thank you. Andy

Hello! I am inquiring about a quote to add insulation in my attic, which is approximately 2,000 sq ft. There is some existing insulation but multiple areas with no insulation. Thank you!
Vicinity of in Lawrence
Multiple cold areas in home. I know where they are but don't know what to do. I also don't know costs so that is great starting point in discussions. Most notable cold areas are in corners of rooms, under kitchen sink, and in our master bedroom. I prefer e-mail communication at this time.
Vicinity of Harvard Rd. in Lawrence
Not sure what insulation services we may need. Possibly we should have an energy audit first. I believe we have a fair amount of blown in insulation in our attic. I think a couple of our windows although double paned are old and ineffective.

We had a mouse infestation in the attic, need to remove all blown in insulation and replace the insulation. Approximately 1300 sq. feet.

Additional attic insulation.
Vicinity of Topeka Lane in Lawrence
4" of blown in insulation in attic. Need bid to see if it is extremely expensive and/or we will do ourselves.
Vicinity of Missouri Street in Lawrence
We live in a 1924 Craftsman home in an older part of Lawrence. There are some extensions on the house that appear to be well-insulated, but our children's room is in an older portion of the house that does not seem to have much insulation. We also have an upstairs hall area that is not insulated. Looking for a quote on what can be done / how invasive it will be to do something / costs vs. savings, etc.
Vicinity of in Lawrence
We recently had our upstairs bathroom remodeled. We put in a heated floor. Our friend that remodeled the bathroom told us that we needed to put fiberglass insulation under the floor. Our basement is unfinished so that isn't that difficult. He also told us that we needed to put insulation from the top of the basement wall to where the base of the house begins. At one time our basement was finished but the people we bought it from gutted the whole thing and all the insulation from that spot. He suggested that we use spray foam for that section. I was just curious as to what that would cost to have done.
