"They came to look at some work on a Saturday and just did it rite then. I wasn't expecting that so was thrilled. Did a great job on a totally miserable project, got it done quickly, cleaned up and cost was very fair. I'd recommend them in a heartbeat"

"Scope of project was removal of existing concrete pavers and hemlock stump, then installing 7-9 rockery flat steps made of natural basalt rockery rocks. We were thoroughly happy with the work from Seattle Rockeries. Harry and his crew were very knowledgeable, fast and friendly. Sharing pics of before and after."

"Ron arrived on time and removed the propane tank on my balcony. I was very grateful for the service because the tank was in a grill and the company taking the grill would not take the propane tank. Ron was very personable and efficient. It was great to see the propane tank go."

"I highly recommend NestEx LLC. We needed a gravel pad prepared for 2 sheds on very short notice, and he truly saved the day. Despite the tight timeline, he went out of his way to accommodate us by coming out on a Saturday to get the job done. His professionalism and attention to detail were evident from the moment he started. He meticulously dug out the soil and leveled the entire area before taking his time to expertly layer layer and compact the gravel. You can tell he takes immense pride in his work; the base is rock-solid and perfectly even. What impressed me the most was his thoughtfulness. After finishing a thorough cleanup of the area, he was gracious enough enough to cover the entire pad to protect it from the incoming rain. He wanted to ensure the gravel wouldn’t be compromised so it could harden properly- a level of care you rarely see. If you want someone reliable, hardworking, and genuinely dedicated to quality, look no further. 5 stars all the way."

"They came out to give me an estimate on the work I requested. They were prompt, professional and honest. Gave me a free roof inspection. Told my roof was in great shape and that I didn't need the cleaning that I thought I was going to need. Gave me some tips and advise on what I could do myself to keep my roof in great shape. They even cleaned the small area on my siding that needed it free of charge. Would definitely recommend these guys and when I do need some roof work done these will be the guys I call."

FAQs for excavation projects in Issaquah, 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.
