Spray foam is made on site from two liquids mixed 1:1. That mix is checked every second we spray and adjusted automatically to keep it on ratio, so the foam cures as the manufacturer designed, which matters for safety and performance. You get a ratio report for your records.
Every job is planned around safe ventilation, protected work areas and clear re-entry times, so your family knows exactly what to expect.
We install spray foam, Rockwool and other insulation only from established manufacturers that stand behind their products.
Licensed in Connecticut (CT LIC #0698762) and Westchester County (WC LIC #WC-40826-H26), and fully insured.

“Our home dates back to 1913 — an uninsulated beach colonial… Cloud 9 made a dramatic difference. They were fast, meticulous, clean, and a pleasure to work with. The quality is excellent — and for the first time, the whole house feels comfortable.”

“Cloud9 insulated my attic with spray foam. The attic space is now the same temperature as the house… Work was done on time and professionally. The price was very reasonable compared to other quotes.”

“The Cloud 9 team was awesome. They clearly explained their process, showed up when they said they would and cleaned up after they left. They even gave me a computer printout from the spray machines showing the exact mixture.”

Cloud9 Spray Foam is an approved Energize CT insulation contractor. The standard rebate is up to $2.00 per square foot of insulation, and there is no income limit. Your Home Energy Solutions visit comes first; we come in second, install the insulation and file the rebate paperwork. In some cases the rebate can come right off your invoice.
It depends on the area, the type of foam and the thickness needed. Closed-cell foam costs more per square foot than open-cell, and removing old insulation adds to the job. We measure every area during a free inspection and give you a written estimate. For many Connecticut homes, the Energize CT rebate of up to $2.00 per square foot lowers the cost.

Yes, for spray foam. Everyone, including pets, stays out during the installation and for 24 hours afterward, and we give you the exact re-entry time before we start. Blown-in fiberglass, cellulose and Rockwool do not require you to leave.
Closed-cell foam is dense and rigid, has a higher R-value per inch and resists moisture, so we use it on basement walls, rim joists, crawl spaces and in flood zones. Open-cell foam is softer, absorbs sound and is used on attic rooflines, in wall cavities and in garage ceilings under rooms. We recommend the right one for each area.
Yes. Smaller projects are welcome, such as one cold bedroom, a single attic or a few rim joists. You get the same free inspection and written estimate as a whole-house job.
