"Mr. Dolloff was prompt in his response to our inquiry into landscaping projects we were considering. He gave us a free estimate on several projects. The cost seemed very fair and we had him complete a quarter of the entire project ~ grooming a hillside with severe erosion and creating a parking area for 2 cars. The hillside is beautiful. Exactly what we wanted and better than we expected. The parking area was not what I would call satisfactory. But in all honesty, they completed both jobs on time but unfortunately it was just the day before we got all that heavy rain the weekend of October 21st. We are planning for him to complete the other landscaping we need down and he offered to clean up the parking area as soon as the weather settles down."

Excavating questions, answered by experts

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.

The answer may vary based on where you live. Residential sewer lines are generally buried 5 feet to 6 feet under the ground. However, it's not uncommon to see pipes buried as deep as 8 feet in colder climates in order to ensure that piping is placed below the freeze line. Digging depth could impact your sewer line replacement cost.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

A perc test takes an average of around two hours, but it can range from one hour up to around six hours. Perc tests that require wider or deeper holes and those that require multiple holes dug throughout your property will take longer because there’s more excavation involved. The actual filling of the hole and monitoring to gauge the rate of percolation should take under an hour per hole.

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.
