"Dj and the team at Roberts construction did a fantastic job building a detached garage at my house from start to finish. His team handled everything from designing and drafting the prints, pulling permits, excavation, and building. If you?re looking for a reliable contractor at a great fair price, Robert?s construction can handle the job."

"As I indicated before Tasha is a dynamo . I was pleasantly surprised at how complete the snow was removed, to the pavement. She has been here twice and has been a joy to have around. Always upbeat and a friendly smile to boot."

"Francis was a top notch professional in all aspects with this job, above and beyond to help us out with our excavation needs. He stayed in communication with us and followed through with our plumber. Had recommendations to help us out all the way through the project. I would definitely refer and hire again. Very honest and sincere. Thank Kelley and Bert."

"It went great!   Glen and his wife Lisa came out and took measurements, and then created drawings needed to get approval from the town for the permits.   Extensive work was done and it took a couple months in total.    We had them building two dormers and a balcony, reroof the home, install tile in the kitchen and bathrooms, install windows, and then paint inside and out.   It was a complicated process but Glen managed things well.  He has a good crew of workers.   We have referred North American Building to other people with similar results!

Excavating questions, answered by experts

While you can save some money by digging your own pool, you may end up paying more in construction equipment rental fees in the long run. You could, however, focus your DIY energies on lowering the cost of leveling your lawn for your pool or filling in surrounding landscaping after construction.

We recommend removing the stump, and grinding is a popular way to do it. You can also dig out small stumps or stumps that have fully decayed instead of grinding them. However, don’t try using acids or fire for killing a tree stump, which is a fire hazard and illegal in many areas.

Leaving the stump alone invites eventual problems, including attracting termites, mold, and fungi.

Sewer lines can be buried anywhere from 18 inches to 8 feet deep, with a common average depth between 18 and 30 inches. The exact depth depends on local factors like climate and soil type. In colder regions, pipes must be buried deeper (below the frost line) to prevent freezing, sometimes as deep as 8 feet. The digging depth can also impact the cost of sewer line replacement. To find the specific depth for your property, you can check the building plans for your system, which should be on file with your city or local sanitation department since permits are required for installation.

You should dig 3 to 6 inches deep for plastic edging. Dig as wide as you need to fit your plastic edging into it—2 inches is usually sufficient.

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.
