"The project turned out wonderfully! Our front garden walk and fountain area were transformed; they were very knowledgeable and easy to work with. They were able to level the area in order to divert pudding water away from the house. The end result was beautiful! We have since moved almost an hour away and have called on them once again to give us insight as to how to transform the garden areas and walkways at our new home."

Hello and thank you for viewing my services, I hope to fix any issue you have and build a relationship off of trust and fine work, if you were wondering what services I offer it’s easier for me to tell you what I don’t, no shingles and no tile, but I do offer grout replacement. It’s a great day when problems go away and projects are finished.

Septic Tanks FAQs, answered by experts

While not strictly necessary for your septic system to operate, septic tank risers are a highly beneficial and wise choice for homeowners. They provide easy access to your tank, which makes regular maintenance, inspections, and addressing issues significantly easier and less labor-intensive. By eliminating the need for repeated excavation to locate the tank, risers can save you money, labor, and energy in the long run. This easy access allows you to proactively manage your septic system, addressing potential problems before they become costly and ensuring the system's longevity. Additionally, some local regulations may require risers, and installing them can help you avoid potential fines or penalties.

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.

A leaking well pipe is quite different from if the well itself is leaking. To seal a leaking well, pour a cement mixture or bentonite into the space between the well casing and the borehole wall. The heavier cement collects at the bottom to form a solid seal, pushing lighter materials like mud and fluids up toward the surface. Professional well installation companies have the equipment to do this properly. 

A septic smell may be harmful because sewer gas is dangerous depending on the exposure amount and length of time. Sewer gas is made up of multiple gases, including hydrogen sulfide, methane, ammonia, and carbon dioxide. Some of these gases, like hydrogen sulfide and ammonia, are toxic to humans and can be fatal in high concentrations or long exposures.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.
