"Called because of issues with slow draining and gurgling toilets the came and pumped, shortly after there was water backing up into my crawl space. When I called back and asked of they had checked the lines for blockage they told me to get a plumber (they had not checked for blockage as they should have, which was confirmed by plumber). When I called back to tell them what had been said the girl got really rude and said they would have to pump again and that they would charge again. Taking no responsibility for the fact they didn't do the job properly the first time. Absolute waste of money. Don't recommend they'll mess your stuff up so you have to pay them to fix it."

Excavating questions, answered by experts

Most municipalities require excavation permits for any significant digging, especially if the excavation affects utilities or public property. However, permits for excavation depend on your local government and the scope of the project. Hire an experienced contractor for your excavation job so that they can be the ones to deal with permitting, not you. 

The easier way to find buried sprinkler lines is to use the plan from the professionals who installed the system. If you don’t have professional plans, listen for running water on your lawn when you turn on the system. You may also spot wet areas, giving you an idea of where the heads are. Once you find the sprinkler heads, you’ll likely be able to connect the dots between them, revealing the system below.

Completion time ranges from days to weeks, contingent on project size, environmental conditions, and regulatory approvals.

There are several different factors that influence how long it takes to excavate. For a foundation, it could take anywhere from three days to three weeks. It can take even longer if you face weather-related delays or an inaccessible site that’s riddled with boulders and rough terrain. It may also take longer if you have clay soil, which is more difficult to dig.

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.
