Get matched with top excavation pros in Saint Helena, CA

Q: Why is slab more affordable than a crawl space?

• <div><p>Slab foundations are more affordable than crawl spaces because they require minimal excavation, as the slab sits directly on the ground or on footers that only sink a few feet into the ground. Crawl spaces require excavation of the entire footprint of the home to several feet below the surface. Not only does that mean higher labor costs, but more materials are necessary for the concrete foundation walls. </p></div>

Q: How much does it cost to dig a well?

• <div><p>Digging a well can cost between <b>$20 and $25,000</b>,<b> </b>depending on your needs. If you&rsquo;re looking to dig a well yourself, all you need is a shovel. If you&rsquo;re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total <a href="https://www.angi.com/articles/how-much-does-well-drilling-cost.htm">cost of drilling a well</a> will average to <b>$5,500</b>.</p></div>

Q: Do you have to dig footers for a deck?

• <div><p>You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.</p></div>

Q: How long does it take to trench 100 feet with a trencher?

• <div><p>It takes two to three hours to trench 100 feet with a mechanical trencher or 10 to 12 hours if digging with a shovel. The total time to dig a trench depends on the depth, width, soil type, terrain, trencher type, and your level of experience. Digging in clay or rocky soil takes longer than soft ground. </p></div>

Q: How far can I hand drill a well?

• <div><p>The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you&rsquo;re using will determine how far down you can dig. </p></div>
