"RDS Plumbing and Heating, owned by Richard Stratton, has provided subpar services that have raised several concerns. I paid $2700 for the installation of a Roth outside oil tank and removal of my old basement oil tank. However, the installation was not completed in accordance with industry standards. The lack of an aerator, which is essential for Roth oil tanks, was discovered by my oil company. Furthermore, the Roth tank was not installed on a concrete slab, thereby voiding my thirty-year warranty. Rich also failed to complete the warranty booklets, which is a necessary step. When I asked Rich about his experience with Roth oil tank installations, he stated that he had done so multiple times. It is also noteworthy that RDS Plumbing and Heating website is currently not operational. Go elsewhere for your Plumbing and Heating projects. "

"Slade and his assistant Rob did an excellent job from start to finish. Slade gave an honest evaluation and quote for what the job would entail. He brought a small excavator, the perfect tool for the job, and he expertly operated it, never once hitting or damaging the brand new PVC fence that was very close to the 110’ long work area. They were kind, respectful, skillful, and thorough. Hopefully I will never need his services again but Slade will be the first person I call if I ever do!"

My window suddenly started leaking; I called the company that installed it and they were going to come in 3 months just “to look at it”. Called SMG & within an hour came to look at it & was dealt with now not after more damage is done. They also put in a new roof as I found another leak...no waiting, no fuss. And all done in one day.

Excavating questions, answered by experts

Trenching is not the same as boring. Boring uses a drill to make a tunnel for underground utilities, but trenching involves digging with an excavator, trencher, backhoe, or shovel. Boring is more precise and expensive, and it’s best for installing utilities underneath buildings, roads, and bodies of water. Trenching is simpler but can cause more disruption to landscaping and ecosystems.

In the United States, a depth of 36 inches (three feet) for underground water lines is the accepted industry standard. This depth varies from location to location based on local conditions. In areas with colder winters, they may be buried deeper to prevent frozen well water pipes : This is usually at least six inches below the frost level. The International Plumbing Code calls for a minimum of 12 inches below grade.

Hard soil could be a sign of overly dry dirt, either from poor drainage or drought. It's important to test the nutrient levels, density, and drainage capacity of your soil to see if it's absorbing water properly. Begin by adding a light layer of water and observing how long the soil retains moisture. If you experience a good deal of runoff, you may need to aerate your lawn, apply a wetting agent, or hire a professional for a closer look.

Yes, professional installations include trenching or borehole drilling required for ground loops.

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.
