"As a retired contractor I can say that these guys do it right. Estimator/salesman (Jay) arrived right on time for his appointment and sent an estimate by email within about twelve hours. Calls were returned, questions answered and proposal was clear and to the point. Appointment was scheduled with no difficulty and the crew - two very tidy men - arrived a few minutes early for the installation. (Jake and a name I did not catch) The job consisted of spraying a confined attic area which contains an air handler and the box beam around the cellar foundation. This was all done cleanly and within a few of hours. Drop clothes were placed every where necessary and the floors were covered more than adequately.  When they left, other than the work they had done, I would not have known they had been here. 

   This was a retrofit to stop heat leakage from the attic area which contains the air handler and which was causing enormous icicles over the front entrance and cold infiltration from the cellar. This was something of an experiment to see what difference the insulation will make this winter. They have other insulation services and I will be calling them to price a couple of other projects as time and cash flow allow.  Keep in mind, spray foam is lumpy. It does not present a flat  surface when finished and no one should expect it to disappear into the background unless it is behind sheetrock. That is another kind of installation.

"Comprehensive estimate, especially compared to another estimate that I got which was cheaper. I ended up getting our house insulated with MetroNY given how detailed and the time and effort spent on giving me the right estimate for the job. The insulation was professional and the manager, Billy, was super polite and took extra time to understand what was going on in between the walls and floors. We now have the added benefit that the noise from the train that runs through our back yard is muffled thanks to the insulation. We await the cold of the winter to see if it worked. Antoinette"

Insulation questions, answered by experts

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.
