Winterizing Pipes: Tools and Supplies

A burst pipe from freezing costs $5,000-10,000 in water damage on average. Winterizing costs under $50 in materials and takes an afternoon. The work is simple: insulate exposed pipes, seal air leaks near pipes, and know where your main shutoff is. No special skills required.
Cost Breakdown
Assessment
Inspect pipes in crawl spaces, basements, and behind walls. A headlamp frees both hands.
Measure pipe lengths for foam insulation sizing.
Insulating & Sealing
Cuts foam pipe insulation to length. A sharp blade makes clean cuts.
Seals gaps where pipes enter the house. Cold air leaks near pipes cause freezing.
Disconnects outdoor hoses from hose bibs. Drain the hose bib after disconnecting.
Consumables and Supplies
These get used up during the project. Always buy these new.
- Foam pipe insulation Pre-slit tubes that snap over copper and PVC pipe. Match the insulation diameter to your pipe size.
- Insulation tape Wraps around joints and bends where foam tubes do not fit cleanly
- Caulk or expanding foam Seal air gaps around pipes where they enter from outside. Use minimal expanding foam; it grows more than you expect.
- Hose bib covers Insulated covers for outdoor faucets. About $3 each.
Safety Gear
- Work gloves (insulation and crawl spaces)
- Dust mask (crawl space work)
Before You Buy Anything
Check if your neighbors already have the tools you need. Borrowing saves money, saves storage space, and keeps tools in use instead of collecting dust.

At what temperature do pipes freeze?
Water freezes at 32 degrees F, but pipes rarely freeze until the air around them drops below 20 degrees F. Pipes in exterior walls, unheated crawl spaces, and attics are most vulnerable. Wind chill makes it worse by pulling heat away from the pipe faster. If your forecast shows sustained temps below 20 degrees, take precautions.
Should I drip my faucets when it gets cold?
Yes, if a hard freeze is coming and you have vulnerable pipes (exterior walls, uninsulated crawl spaces). A slow drip keeps water moving through the pipe, which reduces the chance of freezing. Open both hot and cold slightly. The water bill from dripping is trivial compared to the cost of a burst pipe.
