The boards are tongue and groove - do you think that will make a difference to the drafts?
Would your husband mind sharing his techniques as that is exactly what we will be doing.
We do not have a shed load of money and are struggling to figure out how we are going to get everything done that absolutely needs to be done... :-/ You know, plumbing and electrical upgrades, a kitchen, a bathroom... - the important stuff.
Thanks so much!
