This thread is a shame! You people should know better. LEAVE this job to a PROFESSIONAL duct sealer also called a lagger. Sealing and lagging is a specialty. This is not something for an HVAC technician, duct installer or homeowner to attempt themselves.
You people have already admitted that you are messy when you attempt to do this highly specialized work yourselves. You are simply not qualified for this work. You need to call a certified sealer and lagger who has taken the time to learn the trade, pass a series of exams and become certified. Besides this can be dangerous work to perform.
The national association of duct sealers and laggers have their own website where they post photos of what they call the "Wall Of Shame". It is full of photos of sealing jobs that were done by non-professional heating and cooling people who thought they could do it themselves. (DIYers, they call us)
The sealers and laggers post day and night on their site and they make fun of us all the time. They are making us look like fools. Please stop and call a pro and get the job done right!
