Older homes vs. newer homes
In historic Longmont homes, drains often run through crawlspaces added or modified over the decades, with little insulation. In newer homes the risk is usually the garage: bathrooms over it, or a laundry room on the garage wall. Both are fixable with insulation and, for the worst spots, heat cable.
After the thaw
Once a frozen line is thawed, it's worth running water and watching for a few minutes. If the drain is still slow, ice may have formed behind a partial clog of grease or lint that needs clearing too. If water appears where it shouldn't, the freeze may have cracked an older pipe.
For Longmont homes that freeze in the same spot every winter, insulating the run and adding a heat cable usually costs less than one emergency thaw call.
Common questions
My furnace stopped and the drain outside is iced. Are they related?+
Very likely. A frozen condensate line trips the furnace's safety switch.
How long does thawing take?+
Often under an hour with a steamer or hot-water jetter, longer for long or deeply frozen runs.
Do I need heat tape?+
On lines that freeze every winter, heat cable is a common, inexpensive fix.
