Led by founders Don and Dana Woolliscroft, B-Line Construction is a locally based, family owned business, specializing in septic design and installation of advanced systems, and pumping, septic design services, excavation contracting, site prep, tree removal, and demolition.

The company started in Shelton, Washington in 1991 originally specializing in excavation and slowly building to the company we are today, from septic design to demolition and everything in between.B-Line is a rarity among construction companies in Mason County in that we do all of our own site work, road building, septic design and installation, drainage.

The advantage to you as a customer is having one company with many years of experience, responsible for 'doing it right' from start to finish. We strive for excellence and to that end, cut no corners in either workmanship or materials in order to provide you the best there is. Excavation services and septic design, septic system installation and repair and septic pumping keep the company very busy during the year.
Services
This construction project photo gallery shows some examples of septic system installations, site preparation, excavation, new construction, garage building and landscaping work that we have done in the Shelton, WA area. This project involved installation of a septic system at an existing home. Removal of exsiting trees and vegetation was the first phase, followed by laying the piping for the drainfield, and setting the septic tanks.
I have known Don Woolliscroft of B-Line Construction for many years, both as a friend, and through various jobs done on my property. Projects include extensive excavation for landscaping, septic repair, and installation of an advanced septic system. He is always prompt, pleasant & affordable, and I would be happy to recommend him for a "a job well done".

This company left an invoice from 2014 duct taped to my newly painted front door. We have lived in this house for a year and a half. The previous owner died several years ago. That would not have been hard to find out. Although why they would be billing in this manner almost 7 years later is a mystery. However, if this is the way they handle billing issues, I would not let them do any work for me.

My husband contacted them to do a septic feasibility on land we want to buy, our feasibility period is now almost over and we can’t get a hold of them to save our lives. No one ever answers the phone or calls us back. This is not only unprofessional but is also about to screw us over with this land purchase, very frustrating!

They came out quickly and did their work so quietly I only knew they were here when I saw their work vehicle. The office is very busy, but they are very helpful and are focused on taking care of their customers.

B-line did a great job installing my septic system. I was a complicated job and they completed it quickly and cleaned up the site afterwards. They were friendly and professional. I referred a friend who had a problem with their septic system and they were very pleased with their work too.

They correctly identified a settled septic tank where it had settled several inches on the out-flow end, damaging the pipe to the field. They were then quick to contact me and fully describe the issue as well as the needed repairs and then correctly executed those repairs the next day including lifting the tank and backfilling. Great work. Excellent communication, quick response. And I was in Alaska the whole time of these repairs.

My experience with B-line has been awesome. The work they have done (clearing, grading, and roughing in a driveway) and work they are prepared to do (septic and trenching for utilities) has been impeccable. Don (owner) has gone above and beyond to make sure that i am taken care of and has been there every step of the way. Like anyone who is good at what they do, they are extremely busy, so plan work early...
