Stone Fox was able to help us with a trenching job. Communication was great. Morris made sure we were happy with the outcome and kept us in the loop throughout the process.
Stone Fox Construction replaced our old and failing septic system at our Medical Lake property with quality and affordability. They worked through cold conditions and still finished the job before the deep-freeze window, which mattered a lot for our large family of 10. The scope was handled professionally end-to-end; they coordinated the application/permit process and fees, keeping both the state and us in the loop throughout. We did a new 1,500-gallon, two-compartment tank and also the new, complex drainfield of 750 sq ft! They also handled abandonment of the old tank (pump/rinse, crush, and backfill). Pricing was very competitive for a full replacement, which we financed through the state program. Excellent communication and customer service from Ryan Morris (owner). We’d hire Stone Fox Construction again without hesitation.
Ryan is amazing and so easy to work with. Very fair quote and did a great job!

We'd love to hear from you and answer any questions you may have.

"We had a fantastic experience with Morris and his crew at Stone Fox Construction. From day one, their communication and responsiveness were top notch. After calling around to a bunch of companies, Morris’ customer service was in a totally different league. He was straightforward, respectful, and always on time. And then there’s the part that really matters: the work and the value. Our drainfield had failed, so we needed a full replacement plus a septic installation—not the kind of news and project we anticipated having to deal with. Morris and his team somehow turned it into a smooth, positive experience we’ll actually remember fondly. He was incredibly accommodating with our loan company, moved quickly, and stayed thorough from start to finish. We’re genuinely grateful for the long days they put in—working dawn to dusk—especially during the coldest stretch of the year and holiday time. Thank you guys!"
