How Much Does It Cost to Install a Water Line | CountBricks

James Miller

Understanding the Real Price of a New Water Line

One of the first questions Austin-area homeowners ask our team is, “How much does it cost to install a water line?” The answer depends on a mix of material, distance, access, and labor variables that can swing the final invoice from a few hundred to several thousand dollars. At CountBricks, we combine on-site expertise with AI-driven estimating tools to pin down accurate numbers in minutes, not days.

Typical Cost Range for Residential Projects

Across Central Texas we usually see three tiers:

• Short internal runs (refrigerator or icemaker lines) • $250 – $650

• Medium runs from crawl space or basement to a new fixture • $650 – $1,500

• Full service line from meter to house, trenching included • $2,000 – $5,500+

These figures include materials, labor, basic permits, and standard restoration. Use them as a starting point—then let CountBricks refine the numbers with a real-time voice conversation and AI-generated material takeoff.

CountBricks Rapid Estimate Snapshot

During a recent Barton Hills remodel, our estimator opened the CountBricks mobile app, spoke the scope into the microphone, and within 90 seconds delivered:

• 48 ft of ¾" PEX line with fittings • $312 materials

• Two hours licensed plumber labor • $270 labor

• Permit & inspection allowance • $85

Total projected cost: $667 before tax. The final invoice? $663—less than a 1% variance, thanks to AI-updated supplier pricing.

Key Factors That Drive Cost

Material Type

• PEX: Flexible, fast to install, typically lowest cost

• Copper: Durable, higher cost, may be required by HOA or historic district

• HDPE or PVC: Common for exterior service lines, mid-range pricing

Line Length & Route

• Every additional 10 ft inside walls adds roughly $45 in labor

• Exterior trenching over rocky ground can double excavation fees

Accessibility

• Finished drywall removal and patching increases costs 15-30%

• Tight crawl spaces slow crews, adding billable hours

Local Permits & Codes

• Austin Water inspections require backflow prevention on most new connections

• Failure to schedule re-inspection can lead to costly delays—CountBricks handles the paperwork for you

• AI voice capture builds a scope while you walk the site

• Live materials database updates copper and PEX pricing every 30 minutes

Hidden Costs and How to Avoid Them

Case Study: From Estimate to Flow in 48 Hours

An Allandale homeowner wanted a dedicated water line for a new steam oven but dreaded tearing into finished cabinetry. She opened a live session with a CountBricks estimator and described the kitchen layout while walking through it on video.

• Voice scope captured dimensions and fixture specs in under 4 minutes

• AI takeoff calculated a 26 ft ½" PEX route, two elbows, one tee

• Instant materials cost: $147 • Labor: $220 • Permit: $70

The signed quote hit her inbox within ten minutes. Because CountBricks dispatch integrates local plumber calendars, the install was scheduled for the next morning. By day two, the oven was steaming and the homeowner left a five-star review on CountBricks.com/portfolio.

Pro Tips for Keeping Costs Down

• Opt for PEX where code allows—flexibility reduces wall cuts and labor hours

• Group multiple fixture additions under one permit to avoid duplicate fees

• Use CountBricks AR overlay to pre-plan routes and avoid existing electrical or HVAC lines

• Schedule trenching during dry weather; wet soil slows excavation and increases labor
