PEX Advantages for Boise
PEX (cross-linked polyethylene) has become the standard for residential repiping in the Treasure Valley. Key advantages for Boise homes: it expands up to 3x before bursting (freeze resistant — critical for Idaho winters), it's flexible (easier installation through existing walls during repiping), it resists the pitting corrosion that affects copper in some water chemistries, and it costs 30-50% less than copper for materials and labor.
Copper Advantages for Boise
Copper has a 50-70 year proven track record and remains the premium choice. Advantages: it doesn't degrade from UV exposure (can be used outdoors), it has a longer proven lifespan, some homeowners prefer metal pipes for perceived quality, and it adds more resale value. Copper is also recyclable.
Cost Comparison in Boise
For a typical 3-bedroom Boise home repiping: PEX material and labor costs $6,000-$9,000. Copper material and labor costs $9,000-$15,000. The primary cost difference is in materials — PEX pipe costs $0.30-$0.50/ft vs copper at $1.00-$3.00/ft. Labor is similar or slightly less for PEX due to easier installation.
Our Recommendation
For most Boise homeowners, PEX is the better choice. Its freeze resistance is valuable in Idaho's climate, the cost savings are significant, and the 40-50 year expected lifespan means you'll never need to repipe again. We install PEX using the expansion fitting method for the most reliable connections. For homeowners who want the premium option and longer proven track record, copper is still an excellent choice.

Is PEX safe for drinking water?
Yes — PEX is NSF/ANSI 61 certified for potable water and is approved by all major plumbing codes. It's been used for residential water supply in Europe since the 1970s and in the US since the 1980s.
How long does PEX last?
PEX has an expected lifespan of 40-50 years. The oldest PEX installations (1970s in Europe) are still functioning after 50+ years with no signs of degradation.
Can PEX pipes freeze and burst?
PEX is much more freeze-resistant than copper — it expands up to 3x its diameter before bursting. However, it can still burst in severe freezes. We still recommend insulating PEX in crawl spaces and exterior walls.
