2fardownthread: A little late. Not TOO late.

The article gives good tips and ideas about places to start. Anyone who wants a real eye-opener should take out one of those infrared gun thermometers from Harbor Freight and some incense. The thermometer will show you heat gradients.. differences up and down walls and in high and low places. The incense will show you where drafts and currents are affecting your temps.

You will probably find the usual culprits: cracks around doors or windows, skylights, curtains that create a negative chimney effect instead of blocking off windows, and poorly insulated rooms.

Why not just follow the list in the article? Well, if you look, what you will find is that your house has one or two BIG problems. If you solve those, then the other problems get a lot smaller. You might be able to just block off that one drafty window or cold blast coming under or around the metal front door.

All the little stuff adds up, but if you are pressed for time or effort, there is probably some product or process that can fix that big heating problem in a jiffy. It is almost always cost effective.

Free hint for the day:  recessed entryways with brick or ceramic floors are pools of cold air. Block them off any way you can to keep warm inside air from flowing over the cold surfaces and pushing that cold air all over the floors of your house.

Of course, I'm in an almost 30 year old manufacturered home that's basically a sieve. But still, I do my best to mitigate.

But this is probably the year that we absolutely get the underbelly insulation replaced.

We got one of the rubberized roofs installed about a year or so ago and that made a huge difference during the summer.

In a perfect world, while we have the insulation out, I would try and replace all the grey PB pipe with PEX. But we'll see.

That's a good plan. You should end up paying the plumber less labor hours for not fighting through the insulation.

My house is similar. The insulation underneath had been trashed by animals nesting in it. I kept patching the black PB pipes when they would spring a leak about every other year. In 2020, three leaks happened at once, and two were beyond my skill level.
So, FARK IT! I had the under-house insulation stripped, had all new PEX installed & wrapped, and the under-floor re-insulated. It totaled about $5500 but the peace of mind was worth it, and the teams worked fast! (950 sq ft house, 1 kitchen, 1 1/2 baths) My only regret is not replacing the bathroom faucets and toilets at the same time. Now I don't have the money.
Hope it works out for ya.
