"I needed to stabilize a slope. Norberto presented a plan for a retaining wall and drainage that was both functional and attractive. He provided a detailed bid for labor and materials that was competitive with several other companies He and his crew completed the job efficiently while taking care not to damage existing shrubbery and ornamentals. Norberto is professional and easy to work with. He was very good about coordinating with me. I have and will continue to use his company for other projects."

"Gary and his crew worked very quickly and efficiently on a challenging demolition job that required a great deal of precision. They also did a drain field for my septic system and both projects were completed in 2 days. His crew were hard working, polite and left the job site swept, picked up and very clean. Gary is a pro! No contractor drama. He showed up on time and got right to work. I highly recommend Gaston Brothers Excavating."

"Jireh Construction was fantastic! Their bid was competitive but mostly they were very professional, showed up when they said they would, completed the work faster than expected, and fixed some unexpected discoveries for a very reasonable additional cost. The end product is beautiful. They showed up on time, with the appropriate manpower and equipment to properly perform and complete the work in a timely manner. I highly recommend them and will likely be hiring them to do the sealcoat and striping in the summer when the weather permits."

"Jesse is an incredibly hard worker. He removed around 1000sq ft of blackberry bushes, which uncovered lots of junk left over from previous homeowners. He was generous enough to remove the junk along with the bushes, cleaning up our yard to make it safe for the kids to play."

"Why can we only leave a 5 star rating? Christopher and crew exceeded our expectations for our restoration project. Our project was to replace the decorative wrap on the 16 foot support columns on the entrance porch at the front of our house. The original wrap was 20 years old and parts had begun to rot. During the bid process Christopher suggested that we replace the wooden wrap with a Hardy plank type material that would last longer than wood. (the original wood wrap was painted). During the removal of the original wrap we noticed that the wrap framing was fairly lightweight, just enough to give the wrap something to be nailed to. Christopher removed the lightweight framing and installed a stronger frame. The new wrap that was installed looks considerably better and richer. The attention to detail, down to the router work on decorative panels, is impressive. Christopher was very responsive to our questions and every day they left the worksite spotlessly clean."

Excavating FAQs, answered by experts

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Generally, a trenchless sewer line is worth the cost. If your old system needs replacement, trenchless sewer repair or replacement can save you thousands on excavation costs. Every homeowner’s situation is different, but this method is definitely worth it in a lot of cases.

Depth is not a qualifying component of evacuation. Any human-made cut, cavity, or depression in the earth’s surface is considered excavation. The hole from excavation can be any size, shape, or depth. Excavation is used to create foundations, reservoirs, drainage ditches, and roads. Long, narrow excavations are called trenches and are often used for underground utilities.

It takes one hour to dig a 10-foot trench by hand. Use a trenching shovel with a sharp tip and a long head. Plan for more time if your soil is heavy or rocky. Consider renting a trencher if you’re digging a long or deep trench or if you have challenging soil or terrain. 

If you have a broken sprinkler pipe underground, there will be some signs you can easily spot to locate it and take action. These include leaks, water spouts, flooding, consistently damp areas on your lawn, low water pressure, and grass around the sprinkler head that’s taller and darker than anywhere else in the yard. 

If there are no obvious signs of a broken pipe, you can use tools such as water leak mics, leak noise loggers, audio devices that record leaks, and acoustic testing links. 

Broken pipes can lead to uneven watering, plant damage, and higher utility bills. The longer you wait to fix them the more the repair cost may be.
