"Quick and efficient. Unfortunately, some large globs of concrete outside of the frames were left behind. Is was so wet and a bit muddy, they were probably missed in the cleanup."

"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

"This was an usual project. It was redoing a mini bar. Hard to find a contractor that would do it or had the time. Homepro was great lead by project manager Shir Hadad. Jumped right in there and took it on and got the job done. Really appreciate their professionalism."

"I cannot rave enough about Warren, Oscar and the whole team. In June of 2014, Down aunder Services landscaped our entire backyard (almost a third of an acre), transforming a rocky, dirt-filled wasteland into a gorgeous, lush space with a tiered hill and grass. WOW! We loved it so much that we signed up for their maintenance (gardening) services as well and most recently hired them again for our front yard. The prices are also extremely reasonable and I appreciated the open lines of communication. They finish every job on time and are very transparent about costs and expectations. We are moving to a new home and will be calling Warren again for all of our future landscaping needs there as well.

"Mike and his team were quick, professional, efficient and did a high quality job. The project they did for me was a roof replacement and I am satisfied with everything they did for me. Mike was available for a contact all the time and he saved me some money with his great ideas. My new roof passed all inspections and it looks phenomenal."

FAQs for excavation projects in Descanso, 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.
