"We have used Beko’s Tree for several years now, for both planned and emergency projects, and are grateful for their service! Beko is smart and professional, he prices his work fairly, and he is quick to help when trees have blocked our driveway. He provides sage advice on how to best approach dead and leaning trees, and how to best approach big trees on our high bank property. We highly recommend Beko’s!"

"Pinpoint re-graded and re-graveled my driveway, using a laser to accurately slope the drive, so water would drain away from the house. Re-grading involved excavation of the old gravel (to lower the drive), removal of some large rocks which were encountered, and hauling away of all the excavated material. New gravel was then spread and compacted. I am completely happy with the work and Pinpoint. Pinpoint was professional, with good equipment, arrived on time, did what they said they would do, completed the work promptly, didn't leave a mess, and provided a great looking job. I would definitely hire Pinpoint again."

"They prompt. Professional, and the work is excellent. They should be on Angi's list. They also provide fertilizer and moss control on the grass if necessary. Full service. They are a full service lawn service. Highly recommended."

FAQs for excavation projects in Dupont, WA

Depth depends on the type of installation and the regulations in your area. Water supply lines typically require 24 inches, while drainage pipes are often installed 36 inches below grade. For most general projects, a depth of 12 to 24 inches and a width of about eight inches is sufficient. Sticking to these specs keeps your utilities safe, code-compliant, and easier to maintain later.

When you need to run utilities underground, you’ve got two main options: boring or trenching. Boring employs directional drilling to install utilities without exposing a continuous channel, while trenching requires excavating an open channel to place utilities securely. Directional drilling preserves landscape integrity, whereas trenching provides direct access for installation, albeit with greater surface disruption. This clear comparison helps you select the method best suited to your project.

Plan on 12 hours to dig 100 linear feet when the soil is cooperative and you can work continuously. This timeframe applies when work is performed consistently and methodically. Factors such as rocky soil, tree roots, obstructions, and frozen ground increase the overall duration, demanding extra planning and effort. Comprehensive operational planning ensures that every challenge is managed efficiently and the project is completed on schedule.

If you want your yard to look untouched, laying fresh sod over the trench is the quickest fix. New sod needs 30 to 45 days to root and blend with the rest of your lawn. A local sod pro can provide you with a firm timeline and tips to ensure the grass takes hold and maintains your curb appeal.
