"I had about 5 acres to get cleared out from over growth, I called Freedom Forest Management and a gentleman named Levi was out at my property two day later to give me a quote, the quote they gave me was a little pricey compared to others but they were able to get to it in a couple of days compared to others that were 3-4 weeks out. They did a bang up job cleaned the area up really good even trimmed up a tree I had since he said needed it to help with growth. I definitely got the quality of work I paid for and then some."

Excavating questions, answered by experts

Trenchers can dig holes as narrow as 4 inches or as wide as 4 feet. Check the specifications of the trencher you rent or buy to determine how wide it will cut into the landscape. Better yet, let the excavation company know how wide you’d like the trench to be, and they can help you choose the right trencher for the job (or do it for you).

No, a ditch isn’t a trench. A ditch is an open, relatively shallow channel that’s carved out of the ground and used for drainage purposes. In contrast, a trench is a deeper excavation that’s entirely underground. Trenches have many uses, including gas lines, sewage systems, and electrical wiring. Unlike trenches, ditches don’t get filled back in with dirt after they’re dug.

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.

Yes, you can excavate in the winter, but it might make the job harder. Frozen ground is harder to dig, and snow or ice can make the work site more hazardous. A contractor may need special equipment and techniques, such as ground-thawing methods, to break through frozen soil. Although winter excavation is possible, it may take longer and be more costly than excavating during warmer months.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.
