"I would very highly recommend Sola de Vega. They removed our old grass and some soil, sprayed the area with an herbicide to prevent unwanted grasses from returning, installed a gopher/mole guard, replaced the sprinkler heads, and installed new topsoil and sod. Saul was very quick to respond to our request for a bid and was very reasonable in his estimate and final costs for the project. I can't speak highly enough to characterize his professionalism, rapid follow-up to our questions and concerns, and great communication and friendly demeanor. The project was completed on time, including installation and clean-up, and the results were beautiful."

"So far so good. Snaking of kitchen sink with very old pipes. Hopefully snake did not poke pipes. Only time will tell. Keeping fingers crossed. They did a good job explaining and triple checked for leaks before they left. Of course they tried to upsell and gave us a metal trap they did not quote us upfront for. We would have chosen it over plastic, but price difference would need to be cleared upfront. That's the only negative. Otherwise, thus far we are very happy with the result. Thank you for coming on such short notice and on time! Super appreciated. 4.5-5 stars."

Excavating questions, answered by experts

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

Using a drill to bore holes in the stump's center speeds up the process, whatever method you use. If you don’t have a drill, you can still chainsaw or chisel the stump to make it hollow; it will just take more elbow grease and time. Steer clear of burning the stump to hollow it if you can’t drill some holes in it first. Otherwise, getting it to light, stay lit, and burn right through will be a challenge.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.
