Before You Dig: The Homework Phase
You have decided you need a new shed. That is great. Maybe it is for gardening tools, or maybe it is for that growing collection of outdoor gear. Perhaps you just need a quiet spot away from the house. Whatever the reason, you have some homework to do before you even think about buying materials or breaking ground. Our Custom Sheds Helena team knows that skipping this step is where most folks run into trouble.
Know Your Codes and Permits
First things first, you need to check on permits. It is easy to assume a small shed does not need one, but that is not always the case in Helena. Detached accessory structures, like sheds, under 200 square feet are often exempt from a building permit. They still have to follow zoning setback rules. This means checking how close you can build to your property lines in Helena. If your shed is going to be bigger than 200 square feet, you will definitely need a building permit. The City of Helena enforces the 2021 International Codes. You will want to check their building division for specifics. Our Custom Sheds Helena company recommends a quick call to the City of Helena Building Division. This call can save you a huge headache later on.
Understand Your Soil and Frost Line
This information is important, especially here in Helena, MT. Our soil is not always straightforward. We have everything from rocky ground to areas with more clay. It can vary a lot even within a short distance. This matters because unstable or expansive soil can really mess with a foundation. A professional excavation contractor will tell you that proper site preparation is important here. This preparation helps to prevent shifting soil, erosion, as well as structural instability.
Then there is the frost line in Helena. Water expands when it freezes. If your foundation is not deep enough, that freezing and thawing, which we call frost heave, can lift and crack your shed's base. The state minimum for footings is 24 inches. Helena and Lewis and Clark County have a more strict local requirement. Your footings need to be at least 48 inches below the finished grade. That is a full four feet. If you are planning a permanent foundation, you absolutely need to hit that depth. This helps to avoid problems down the road with your Custom Sheds Helena project.
DIY or Pro? Making the Call
For smaller sheds, like 8x8 or less, a gravel pad can be a good DIY option. This is if you are comfortable with some serious digging as well as leveling. A gravel pad is cost-effective. It also provides good drainage. You will need to clear the area as well as excavate a few inches. Then you will lay down some landscape fabric. After that, you will bring in and compact a good layer of gravel. Our Custom Sheds Helena team always makes sure it is level.
Here are times when you should seriously consider calling in Custom Sheds Helena or another local professional:
- Larger Sheds: Anything over 200 square feet, or if you are storing heavy equipment, really needs a more solid foundation. This includes a concrete slab as well as concrete piers. These foundations require precise leveling. They often need rebar as well as getting the mix right. This can be tough for a do-it-yourself person.
- Tricky Soil: If you know you have unstable soil, or if you are building on a slope, a professional can assess the ground. They can recommend the best solution. This might include helical piers. Helical piers are designed for our local conditions. They can reach down to stable layers for your Custom Sheds Helena project.
- Permanent Structures: If you want your shed to be a truly permanent fixture, like a workshop or an office, a professional-grade foundation is a must.
- Footings Below Frost Line: If your shed foundation requires footings that go down 48 inches, that is a lot of digging as well as precise work. It is often worth hiring an excavation company. This helps to make sure it is done correctly as well as to code.
During the Build: Getting it Right
Attention to detail here is important. This is true whether you are doing it yourself or supervising a professional. For a gravel pad, you will want a good, thick layer of compacted gravel. This is typically 4-6 inches. It should have a border to keep it in place. Our Custom Sheds Helena team makes sure the site is graded. This ensures water drains away from the shed, not towards it. Good drainage is essential. It helps to prevent moisture problems.
If you are going with a concrete slab, the site needs to be perfectly level as well as compacted. Rebar or wire mesh is important for strength. This is especially true with our freeze-thaw cycles in Helena. You must make sure the concrete is poured to the correct thickness. It also needs to cure properly. This is not a step you can rush.
After the Foundation: Protecting Your Investment
Once your foundation is in, you are not entirely done. You need to protect it. You must make sure there is good drainage around the entire shed. This might mean adding gutters to your shed. It also means directing the runoff away. Or it means making sure the surrounding landscaping slopes away from the foundation. Our Custom Sheds Helena team advises you to keep an eye out for any signs of settling or cracking. This is especially important in the first year. If you see anything concerning, you should address it quickly. A small crack can become a big problem if it is ignored.
Building a shed is a great project. A solid foundation is what makes it last. Do your research as well as know your limits. Do not be afraid to call in the experts when you need them. It is an investment that pays off in the long run for your Custom Sheds Helena project.
