You could say we have a reputation for green building expertise and spectacular design – but we prefer to let our work speak for itself. We are dedicated to all those homeowners in search of a new home full of design, imagination, and make-you-swoon features. No doubt, Sussex will create the new home of your dreams (and of your neighbors’ dreams). At Sussex Construction, we are known leaders in the building industry. We combine good taste and getting things done with exceptional results. Because it is not just about what you build. It’s how you build it. All this without burning a hole in your pockets. If you are searching for new custom home builders in Helena, MT your search is over!

"We are one of a handful of new construction purchases (within the last year). During the build process, they were great to work with. Once we closed, all that changed. We have to run space heaters during the winter months (a brand new home) due to the design of the ductwork and Sussex wouldn't lift a finger, we have flooding at the entrance to our property, and once again, Sussex did nothing. We had fixtures in the wrong place, and some were not what we ordered at all, and guess what? they did nothing!!.. As we began to speak with others in the community, we learned of a horrible reputation throughout Helena, as well as, a horrible place to be employed. All in all, stay away from Suxxit construction at all costs. Money is their motivation, not happy families"

Excavating questions, answered by experts

Trenches are 12 to 24 inches deep and 8 inches wide. However, the right depth for your trench will depend on the nature of your project. For example, if you’re digging a trench as part of a French drain installation, it should be 18 inches deep. An excavation professional can explain how deep your trench should be.

Most residential basements are 8 to 10 feet deep. You can dig deeper depending on building codes, but it does become more difficult. You’ll likely need to install stronger foundation walls and additional supports to handle the increased load. Depending on the water table, you may also need a water management system. Clay soil can support a deeper foundation than sandy soil. A structural engineer will be able to tell you the maximum, feasible depth.

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. 

The rules for trenching and excavation include setting up and following safety protocols, learning how to use tools and machines properly, and ensuring there is a safe exit for all workers. Keep heavy equipment and materials away from the edge of the hole or trench. Call the 811 dig line before starting any excavation or trenching project to ensure you don’t hit any electrical or gas lines.

This depends on your location. Sewer lines can be buried anywhere from 18 inches to 8 feet deep. People in colder climates will have deeper sewer lines than people in warmer climates due to the dangers of the frost line and freezing pipes. Permits are required for all aspects of septic system installation, so the city should have the building plans for your system, which will tell you how deep your lines are.
