Blown-in cellulose--holes not plugged: problem?
In May our 1930 2-story wood frame house had cellulose blown in from the exterior by a professional. The house is sided, with a bit of foam board under the siding, then regular clapboard. He drilled in the top and bottom of the bays, lifting only the course of siding needed to access the bay.
The possible problem: I did some searching/reading here before the job, and thought SOP was to plug the holes in the wall after the fill. He did not do that--so all we have over the holes (they might be 1.5" diameter) is the vinyl siding. The cellulose is packed in there pretty tight--he showed me a couple of bays.
When I asked him if he would plug, he just said no and I didn't press him on it. I was kind of surprised. We had the work partially paid for by a program offered by our natural gas utility--we paid 1/2, the gas co. paid the other 1/2. We did not choose this vendor, we sort of had to use him at the recommendation of the utility. They seem to have a decent reputation and have been in the area a while.
It's been bothering me since then that there's no plugs there. Seems an obvious entry way for dampness, etc. Do I have an problem here? It having these fill holes plugged essential? They are not exposed to direct rain or snow. I don't know if he was trying to cut corners but its seems pretty simple to jam a plug in there as you move to the next bay. . . . Should I go back to him to get him to plug (he did the work and would know where he drilled), get someone else or let it go?
Thanks--sorry about the long post--
