Portable Sawmill Service: What Homeowners & Landowners Should Know Before Booking

If you're considering turning storm-damaged trees, fallen timber, or standing logs into usable lumber, a portable sawmill service can be one of the most efficient and cost-effective solutions. Instead of hauling heavy logs to a traditional mill, the sawmill comes directly to your property. This saves time, money, and the headache of moving oversized material.

Across Wisconsin and the Midwest, more homeowners and landowners are choosing portable milling for custom projects, homestead builds, hobby woodworking, and live-edge slabs. Below is everything you should know before booking a portable sawmill service.

1. Check Experience, Reviews, & References

Portable milling requires skill, both in operating the mill and in reading the logs to produce straight, clean, high-quality lumber. An experienced sawyer will:

• Provide clear costs and timeline 

• Understand how to maximize each log

• Produce consistent and straight cuts

• Maintain safe work practices

• Troubleshoot issues like internal rot or metal

Before booking, ask for:

• Google reviews

• Photos of past projects

• References if available

2. Understand Pricing, Rates, & Possible Extra Costs

Portable sawmill pricing can be confusing if you’ve never hired a mill before. Rates vary widely across Wisconsin and the Midwest, and each service structures pricing differently depending on their equipment, travel distance, setup time, and the type of lumber you want to produce. Some sawyers charge based on the amount of lumber they cut, while others charge strictly for their time on site.

Before booking, it’s important to understand how your sawyer structures their fees so you know exactly what to expect (and so you can compare services fairly). In general, most portable sawmill services use one of three pricing models:

• Per board foot: You pay based on the lumber produced

• Hourly rate: Time on site determines cost

• Day rate: One fixed fee for a full day of milling

In addition to the base pricing model, nearly all portable sawmill services have additional costs, such as travel fees, blade use, and fees for log preparation (if logs must be moved or cleaned).

→ Our pricing at Mustard Seed is simple and transparent: $500 day-rate + travel + blade use. You can even get your first blade free. Unlike most services, Mustard Seed is also comfortable working with metal-risk logs. Just note that hitting metal typically requires a new blade. This straightforward approach helps homeowners budget clearly without hidden surprises.

3. Confirm Capabilities, Limits, & Lumber Specifications

Not all portable sawmills are built the same. Each machine has specific size limits, cutting abilities, and optional features that determine what kind of lumber you can get from your logs. Before you book a service, it’s essential to make sure the sawmill can actually a) mill the trees you have and b) produce the type of lumber you want. A quick conversation up front helps avoid surprises on milling day and ensures you get the best value out of your logs.

Log Diameter Capacity

How large of a log can their mill accept? Oversized hardwoods like oak, maple, and walnut often exceed smaller mills' limits.

Maximum Slab / Cut Width

If you want live-edge slabs, this number matters the most. Wide slabs require a mill with a wide throat.

Maximum Cutting Length

Some mills are limited to around 12–16 feet unless extensions are available.

Board Thickness & Specific Dimensions

If you're aiming for 4/4, 6/4, or 8/4 lumber, confirm the sawyer can cut to your desired dimensions accurately and consistently. If you’re looking for a specific type of cut, check whether they can produce live-edge slabs, dimensional lumber, quarter-sawn or rift-sawn boards (important for stability and certain hardwoods)

4. Preparing Your Logs & Site Requirements

Proper prep can significantly reduce milling time which saves you money. It will also improve lumber quality and provide an overall better experience for everyone involved. These are key requirements for most portable milling services: 

• Logs stacked neatly in an accessible location near the milling site

• Logs raised off the ground using dunnage or small diameter logs

• Logs should be clean and free of dirt and metal objects

• Site should be relatively flat and level, about 30 feet by 30 feet

• The area should be free of obstacles like stumps, rocks, or branches.

5. After the Milling: What to Expect

Once the milling is complete, you’ll have a pile of green lumber, by-products, and a much better idea of what your logs produced. Here’s what typically happens next and how to make the most of every part of the process.

Wood By-Products: What Gets Left Behind

Portable sawmills generate several natural by-products. Most sawmill services, including Mustard Seed, leave these on-site for the homeowner to use or dispose of as they choose. You can expect:

• Sawdust: Ideal for garden pathways, composting, animal bedding, or mulching around trees.

• Bark & slab offcuts: Often used for firewood, bonfire kindling, or rustic garden edging.

• Short scrap pieces: Great for small DIY projects, campfire wood, or smoking wood depending on the species.

Sorting and Stacking Your Green Lumber

After milling, you’ll have stacks of green (freshly cut) lumber, which needs proper handling right away to prevent warping or mold. Best practices for managing your lumber after milling:

1. Sort boards by thickness and length: This makes stacking more stable and drying more consistent.

2. Choose a level, elevated base: Use pallets, blocks, or timbers to keep wood off the ground and away from moisture.

3. Use “stickers” between each row: Stickers are thin, evenly spaced strips of wood that let air flow between the boards. Use consistent spacing (typically 12–24 inches apart) and keep stickers aligned vertically from layer to layer.

4. Cover the top, but keep the sides open: Shade and airflow are crucial. A simple metal or plywood sheet on top works well. Avoid tarps unless they’re ventilated.

5. Label your lumber: Species, thickness, date milled, and any special notes. Future you will appreciate the clarity!

→ Mustard Seed Wood Transformations is always happy to walk customers through best stacking practices before leaving the job site. We can cut stickers from your logs to set you up for success. 

Drying Your Lumber: What to Know

Fresh lumber needs time to dry before it’s ready for woodworking or construction.

Air-Drying: This is the most common method for homeowners.

• Expect 1 year of drying per inch of thickness as a general rule (varies by species and weather).

• Hardwoods like oak and maple take longer; pine dries faster.

• Waxing or sealing the ends of slabs helps reduce checking and cracking.

Kiln-Drying: If you need lumber sooner, or want more stable boards, kiln drying is an option. Mustard Seed can help advise on kiln-drying availability if needed. Any indoor use product should be kiln dried and heat sterilized to kill any life left in the wood. Bugs coming out of a finished table can be a real eye opener!
