"not that great. basically paid $99 to get an estimate. included cleaning roof and minimal repairs. took a while to get appointment, and then when they came, they didn't even do the work! gave a really big estimate and then re-seheduled to have someone else do the work. they wouldn't totally replace the roof, gave different estimates to repair, I went with a different company to do a full roof rplacement."

We have been having tree root problems with partial clogging of the yard drains for several years Our neighbor's trees were causing a pain in the drains. Previous hired rooter companies weren't able to remove all the roots. About 80 feet of pipe is under a concrete walkway. I was told told by the previous rooter companies that I might have to break out the concrete (big bucks!) and replace the pipe in several years.

I decided to call The Drain Co after reading the positive reviews on Angie's List. Ramon arrived on time and was polite and was very knowledgeable --- 20+ years experience! He explained how the procedure was to be done correctly. He used the proper size cutter (the previous companies used a small coil type rooter after giving up using a cutter, which only partially rooted through the root mass). He knew the exact cable feeding rate to resistance met to get a complete root cut, and when to pull the cable and repeat the process. He pulled out a 7 foot string of roots which at first I thought was a baby python. After clearing the roots he applied a root killer which relieved my anxiety about replacing the pipe which was under concrete. Ramon did a thorough clean up afterwards. Will definitely use The Drain Co again and highly recommend them!
Star (owner) called next day to make sure I was satisfied --- answer: extremely satisfied!

FAQs for excavation projects in San Dimas, CA

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.
