Experts Since the 1970s

At McNair, we are a family business, and because of that, we are passionate about what we do. Since the 1970s, satisfied customers all over the Evergreen State have been turning to us for quality septic installations. But why? Our family has been designing and installing septic systems for over 50 years. As a respected legacy business, we guarantee 100% customer satisfaction because our knowledge is second to none, ensuring you get a system that lasts.


Percolation testing

Before work begins, we need to know if your land is even suitable for a septic system. As part of the service, we include percolation testing that includes measuring the water absorption timing.


Gravity and aerobic septic systems

A standard waste system uses gravity to direct water flow away from a property. Aerobic systems use oxygen and tanks to treat water. McNair can consult on both of these systems.


Septic drain fields

From a septic tank, waste is carried away and dispersed into a nearby field where it naturally breaks down. We specialize in consultation and installation of these kinds of septic systems.


From the moment you give us a call, we can start the process of obtaining licenses and permits for installing septic drainage systems, and we work for you to make the complex process easier.


A Wide Range of Products

Because we are a family business, we have no obligation to industry manufacturers. Our dedication lies solely with our customers. As such, we offer a wide range of products that are needed to get the job done instead of flogging the parts we have been paid by partners to sell. This kind of independence means we only offer products that we know benefit the job and not line our pockets. In short, you can be confident we aren't getting kickbacks for sub-par parts.


All Your Septic Drain Field Needs

Most people will work with 3 different contractors for a septic tank installation. However, our Cowlitz County gravity septic system installation is a complete package working with us only:

  • Our services include site and soil testing before we even start, to test ground suitability.
  • After testing, we will consult with you about the best design and system for your property.
  • We also offer an all-in-one solution, so you only need to work with one contractor.


Start to Finish Transparency

If you have ever worked with contractors, then you know some aren't exactly the most reliable services. McNair is no such service! Our septic services are second to none in terms of quality, but also transparency. We keep you informed of every decision at every step in the project, from consultation to the finished product. You are never left wondering what is happening as we keep you informed of project timelines, any updates you need, and the next step in the sequence.
