That's fine, have them go from outside. They cost me a fortune in patching and repainting. It did not make a difference in the floors being cold. Waste of 3500
After you get a quote if you decide to go with them, they will insulate every little piece every little inch every little Nook and your house if you ask them to they may Overlook things like floors but if you ask them to they will insulate anywhere you ask them to at no extra charge. They did great for us they insulated in between our floors the house is better the whole atmosphere is better. It did stink for about 2 weeks.
