Our Solutions

The Blue Alder


We offer a comprehensive range of excavation services, including site preparation, trenching, foundation digging, and basement excavation. Whatever your excavation needs, we have the expertise and equipment to get the job done efficiently and effectively.

If you’re experiencing issues such as standing water, soggy or waterlogged areas, or erosion on your property, you may benefit from our drainage services. Our team can assess your property and recommend customized drainage solutions to address these issues and prevent future water-related problems.

A French drain is a trench filled with gravel or rock that contains a perforated pipe. It’s designed to redirect water away from problem areas, such as around foundations or in low-lying areas prone to flooding. French drains are an effective solution for managing excess water and preventing water damage to your property.

The duration of an excavation project can vary depending on factors such as the size and complexity of the project, soil conditions, and weather. We strive to complete projects in a timely manner while maintaining the highest standards of quality and safety.

Permit requirements vary depending on the scope of the project and local regulations. Our team is familiar with the permitting process in Maple Valley, WA, and King County, and we can assist you in obtaining any necessary permits for your project.

Yes, we have experience working on both residential and commercial projects of all sizes. Whether you need excavation and drainage services for a backyard landscaping project or a large-scale commercial development, we have the expertise and resources to meet your needs.

Simply contact us to schedule a consultation. Our team will meet with you to discuss your project goals, assess your property, and provide personalized recommendations and a detailed estimate. We’ll work closely with you throughout the process to bring your vision to life and ensure your complete satisfaction.

What People Are Saying

Andy took great care
Andy took great care to solve my drainage and excavation needs in a very cost effective way. The work was done over 7 months ago and has held up perfectly

We will definitely be working with them again on future projects
We worked with Andy Duckworth and Blue Alder Excavation Services to help us clean up fallen trees from a windstorm. He also helped us clean up our logging roads, removed stumps, graded, and spread gravel. He was super easy to work with. Very polite professional, and yet very personal. We will definitely be working with them again on future projects. Looking forward to visiting their farm this spring.

Andy is very responsive, reliable and great to work with. I never knew my yard could look this good and I never knew the potential my yard had until talking with him. I highly recommend Andy and his team at Blue Alder!

Shoutout The Blue Alder
Shoutout The Blue Alder for the awesome work on our front yard. They were a spur of the moment choice after seeing their sign in a neighbors front yard. Andy and his team completed a front yard remodel to really improve our curb appeal. Stump grind, plant removal, leveling, brick work, drainage, and hydro seeding. Two weeks in and the front yard is looking amazing with grass coming in fast!! The best part of hiring The Blue Alder was the communication which is very important when working on a project like this, nothing was missed. 10/10 would recommend.
