When our husbandy and I felt a draft in the spare study room, I researched all of the reasons why this might occur! A lot of people on message boards felt that I might have an issue with the ductwork above the study room! I really thought it was worth looking into the duct work, so I went into the attic with a flashlight and a package of duct tape, and the people on that message board were 100% respected and there was an issue with the ductwork above that room, however unluckyly, the task was too immense for me to complete on our own. I did not realize that until I was halfway into the task. I did not have the right materials and I was having a lot of trouble reaching some of the areas. I finally provided up and called a supplier to finish the task, and my husbandy wanted me to call a supplier when both of us first started the project, even though I absolutely thought I could service the ductwork issue on our own and I did not want to waste cash that was unnecessary.The supplier brought a partner and both men took almost an second to complete all of the ductwork repairs. The men also found a couple of additional spots that needed tape and sealing. It would have been nice to complete the project on our own, but in the end I was ecstatic to have a trained professional complete the task. It would have taken me all afternoon to get that task done and those men tackled it in less than 90 minutes.
