It is that time of the year again folks and most of us last year had a whopper of a cold winter.
I did a inspection today of a home for drafts and so forth and it was a good day to do it since the inside temp was 76 and outside temp 51 all day.
I found vents where the flex duct had rotted/ripped away so heating was going to the crawlspace instead of the house.
I found weatherstripping on windows that had vanished away on the bottom sashes of the windows and I found doors with worn out weatherstripping that had visible light coming from it.
In addition using smoke and with the help of a windy cold day I found numerous plug/switch outlets with drafts and plumbing shutoffs that had massive air coming around them.
Most heat loss occurs in the attic and blown insulation is fairly cheap, oftentimes people don't need a whole new blown attic however but you should check to make sure it is covered uniformly if you have access to it but make sure your eves can breathe.
Preferably with the foam inserts and insulated up against. It is also a good time to make sure bathroom exhaust fans still have their ducting attached as I found 2 today that had no vents at all just venting straight out onto the drywall in the bathrooms and some serious mold/mildew issues.
If you live in a place like me( I rent a decent house ) that has single pane windows, the plastic really does work. I not only suggest it inside but outside as well( use gorilla tape outside! ). A house should never be sealed up 100% so I do my side and rear windows, as the clear isn't bad but it is a bit unsightly, but if it is stopping drafts which make you feel colder and losing heat, who gives a shit.
To put foam draft blockers on plugs/switches, weatherstrip doors/windows/shutoffs, cover your windows and spot some insulation in the attic and re tape busted ducts will only cost you around $100 now if you do it yourself, and trust me if the winter is bad, you'll get a full return and then some on investment if you have issues.
Also make sure your windows and doors are caulked ALL the way around. I constantly find windows and doors where the top casing is not sealed.
While you are at it, make sure the thresholds under the doors are sealed as well. Not only for cold but water/insects invade in that spot.
If your house was built right, insulated right and up to modern codes most of these things can't be improved upon, however that is a big if as most contractors don't give a shit and may have not spent the 5 dollars to seal that door, or caulked holes made for plumbing, electrical, hvac.
I'm sure most if not all of you already knew all this , but being in a 4200 square foot $750,000 home today to find the issues I did made me think I should bring it up.
