 Trustindex verifies that the original source of the review is Google. Frank was wonderful! Came for an estimate and was open to all the work we were hoping for, talked us through it, recorded videos to outline the work, and shared a reasonable estimate. The guys who came to work were also great - scheduled quickly, work was done in 2 days, and the final result looks great with little mess! Overall we're really happy here in Redmond and will definitely call on them again :)

 Trustindex verifies that the original source of the review is Google. Frank and his crew are reliable, communicate well, and are thorough. As a new homeowner discovering deferred maintenance/repairs coming up on their due date on nearly a weekly basis Frank's experience and intuition on what projects to prioritize, how much to invest, and how to approach the projects to ensure they could be picked back up when funds/time were available has been invaluable. Joe was the foreman from FtS on my various projects (driveway tear-out/replacement, french drain remediation and installation, catch basin installation and directed runoff, gravel drive cleanup/compaction, and culvert remediation) and kept me in the loop as work progressed and when opportunities arose to improve the project or take care of other future issues was happy to work through the process and scope. An example of a particularly important one was when I noticed issues with the old house gutter drainage adjacent to the new driveway and we were able to get new drainage pipes installed just days before the pour so that I didn't need to potentially tear up my nice new driveway just a few years down the road. There's other nice touches too like them having their own portapotty brought on-site and keeping things clean/covering damaged grass with hay. I've got a lot more projects to do and FtS will be doing them!

 Trustindex verifies that the original source of the review is Google. We had had them come out and dig out for our addition foundation and backfill once it was poured. Frank was very prompt when coming out for the bid and once we agreed to use them, his guys were out the following week to start. They finished their scope of work in a very timely mannor and left our yard very clean after they were all done. Highly recommend.

 Trustindex verifies that the original source of the review is Google. Contacted FTS for a bid on some clean up on my property. They responded and checked out the site, gave me a bid later  the same day. With a bid that was very reasonable. They came out and performed the work and completed the job in the promised time.  I am very happy with the work they did and will be hiring them again for further projects. Rob Henson

Absolutely. We provide excavation for septic system replacements, including tank removal or decommissioning, new installation, connection, and backfill.

Yes, if the ground is workable. Septic system drainfields are required by code to done in dry weather. Some winters here are wetter than others, but we can always find a dry day here or there to complete the weather critical portion of the work.
