"JPC team did an excellent, professional job on our storm water sump pumps related project. (Two sump pumps were working; they did not need repairs.) 1) Cut and replaced two broken pipes; installed new valves 2) New float sensors installed and set to auto-start the sump pumps 3) long outflow pine, connecting to city's water drainage system, was cleaned using long snake and high pressure water pump combination. 4) successful final test with water filled in water chamber and sump pumps working 5) JPC gave warranty for work done and signed up for once-a-year annual maintenance visit in October."

"With our rather old cabin-style home, the plumbing from the kitchen sink had a plug of hardened grease over 30 years old. We discovered this the first day when they drilled through it with a snake; we had them return a couple of days later with a hydrojet unit to clean it out. Our house is located in the mountains, and may not be particularly easy to get the equipment out here, but they had very little difficulty. They used a lengthy hose to go around the back of the house, then sent the nozzle through the pipe behind the trap to clear it out. I was originally concerned about navigating past the elbow joints in the pipe, and the fact that we have a septic tank that I didn't want to fill up; but neither was a problem, and the job was done in about an hour. The sound of the drain flowing never sounded so sweet."

"Going through a remodel can be very stressful but with Sami And Sons Remodeling was very good to work with. We wanted to install in tiles in my bathroom and also wanted to paint the walls. Sami And Sons Remodeling were very transparent. They are very concious about quality work and obtaining permits, inspections in every step of the way. The work crew was very good. Sami And Sons Remodeling's crew were polite, worked hard and even made sure my cat and dogs didn't escape during the remodel process. That was very important to me."

FAQs for excavation projects in San Mateo, 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.
