What We Do: Underground Utilities

Water Service

Water Service Whatcom County - Installation and Repair

Your water service is the connection from your house or business to the city meter, well head, or water association meter. We provide water service lines for new construction as well as repair or replacement of existing water service lines.

If you’re experiencing higher than normal water bills and your water meter is turning when no water is flowing in your home, this is an indication that you have a leak between your meter and home.


  • On-site assessment and leak detection

  • Waterline replacement

  • Trench or trenchless; continuous plastic pipe that exceeds high pressure requirements

  • On-site connections to the house line as well as to the meter

Stormwater Connections

Stormwater Service Whatcom County - Agate Northwest

Rain or stormwater must be diverted away from structural property or long-term damage will occur. We can provide foundation and downspout drainage on new construction as well as remediate clogged or improperly installed downspout drainage on existing structures. This includes connecting to municipal stormwater lines or daylighting to street curbs or road ditches.


  • New construction foundation and downspout drainage installation

  • Remediate clogged or improperly installed downspout drainage

  • French drains and curtain drains for surface water problems

sanitary Sewer systems

Sanitary Sewer Service Whatcom County Install and Repair

  • New construction

  • Remediation of older construction

  • Camera inspections of existing pipe to identify problem areas

  • Replacement of substandard clay tiles with modern materials

Electrical Conduit

Electrical Conduit Install Whatcom County - Agate Northwest

Whether adding electrical service to new construction or adding a new circuit to outside lighting, well pump, or automatic gate, we can run subsurface conduit that’s ready for an electrician. We can do this much cheaper than the electrician since they usually sub contract this aspect out while up-charging for the subcontractor.


  • Industry standard glued conduit according to local regulations

  • Conduit installed with pull rope for pulling wire

  • Mole tunneling under sidewalks and driveways, eliminating costly concrete replacement

Gas Lines

  • Coordinate with gas company for inspections and final connections

  • Only approved gas line used

  • Highest standards in material and workmanship

Mole Tunneling

Mole Tunneling Whatcom County Agate Northwest General Contractor

In situations that require tunneling underground in straight runs and up to 3” in diameter, we have the ability to use a pneumatic mole. This is ideal for underground electrical conduit and any straight pipe less than 3” in diameter. Mole tunneling is cost effective and perfect for crossing under sidewalks and driveways.


  • Minimal site disturbance – only need an entry & exit trench

  • Straight runs up to 3 inches in diameter

  • No damage to sidewalk or driveway
