What Are Sawmill Services and How Do They Work
Two 2×2 pieces can cost you double compared to one 4×2 — even if they come from the same log.

Sawmill services involve processing raw logs into usable timber for construction and other uses. After trees are cut, logs are placed on a sawmill machine where they are cut into standard sizes like 4×2, 3×2, and 2×2. In Kenya, sawmills can be stationary or tractor-powered (PTO), allowing milling to be done directly in the forest or at timber yards.
4×2 (8 ft) = 56KSh
2×2 (2 pieces) = 112KSh
Same log, different cost.
How Logs Are Prepared Before Milling
Before milling begins, logs are carefully prepared to ensure efficient cutting and minimal waste. After a tree is felled using a power saw, branches are removed and the trunk is cut into manageable sections, usually 7 to 8 feet long. These lengths match common construction sizes and make handling easier. The logs are then aligned properly on the sawmill, with the thicker base positioned first to produce stronger, larger timber pieces like 4×2 before cutting smaller sizes.
Sawmill Cost Calculator (Per Foot Pricing Examples)
Milling is charged per foot per piece — the more pieces you cut, the more you pay.
Timber Size | Length | Cost Per Piece |
4×2 | 8 ft | 8 × 7 = 56 KSh |
3×2 | 8 ft | 8 × 7 = 56 KSh |
2×2 | 8 ft | 8 × 7 = 56 KSh (per piece) |
2×2 (2 pieces) | 8 ft each | 112 KSh total |
Types of Sawmills in Kenya (PTO vs Stationary)
Workers operate a blue tractor, cutting and stacking timber in a forested area.
Sawmills in Kenya are mainly categorized into PTO (tractor-powered) and stationary sawmills, each suited for different working conditions.
Experienced operators always start cutting from the base of the tree because that’s where the strongest timber comes from.
PTO sawmills are mobile and powered by a tractor using a Power Take-Off (PTO) system. They are commonly used in forests where trees are harvested, allowing logs to be milled on-site. This reduces transport costs and makes operations more flexible.
Stationary sawmills, on the other hand, are fixed in one location, usually in timber yards or towns. Logs must be transported to these mills, but they often offer more consistent cutting and higher processing capacity.
How Tractor-Powered (PTO) Sawmills Work
Tractor-powered sawmills use a Power Take-Off (PTO) system to transfer energy from the tractor engine to the milling machine. The tractor is connected to the sawmill via a rotating shaft, which drives the cutting blade at high speed.
Logs are placed on a metal track or platform and aligned properly before cutting begins. As the blade moves through the log, it slices the wood into required sizes such as 4×2, 3×2, or 2×2.
These mobile sawmills are ideal for forest operations because they allow timber to be processed on-site, reducing transport costs and making the entire harvesting process more efficient.
Timber Milling Cost in Kenya (Per Foot Explained)
In Kenya, timber milling is commonly charged per foot, making it important to understand how the pricing works. The average milling cost is about KSh 7 per foot, meaning every timber piece is calculated based on its length.
For example, an 8-foot timber piece will cost:
8 × 7 = KSh 56
If multiple pieces are cut from the same log, each piece is charged separately. This means more pieces result in a higher total cost. The final price also depends on factors such as the number of cuts, wood hardness, and operator efficiency, making planning essential to control costs.
Timber Sizes Explained: 4×2, 3×2, 2×2 and Their Uses
Timber sizes in Kenya are measured in inches and are selected based on their role in construction. The most common sizes are 4×2, 3×2, and 2×2, each with specific uses.
4×2 timber is strong and used for structural framing, beams, and load-bearing sections. It is usually cut from the thicker base of the tree.
3×2 timber is widely used in roofing for rafters and supports, offering a balance between strength and cost.
2×2 timber is lighter and mainly used for purlins (parine) and secondary supports. It is often cut from smaller sections or split from larger timber pieces.
How much do sawmill services cost in Kenya?
Sawmill services in Kenya are commonly charged per foot of timber, with the average cost being around 7Ksh per foot. The total cost depends on the length of the timber and the number of pieces produced.
How is timber milling cost calculated?
Timber milling cost is calculated based on the length of each timber piece. For example, an 8-foot timber piece is charged as:
8 × 7 = 56Ksh per piece
If multiple pieces are cut, each is charged separately, increasing the total cost.
Why does timber size affect milling cost?
Timber size affects cost because milling is charged per piece per foot. For example, one 4×2 piece may cost less than two 2×2 pieces of the same length, since more pieces increase the total number of billable feet.
What timber sizes are commonly produced in Kenya?
The most common timber sizes include:
4×2 – structural framing
3×2 – roofing structures
2×2 – purlins (parine)
These sizes depend on the thickness of the tree and the intended use.
What is the standard length for timber in Kenya?
Most timber is cut into 7 or 8 feet lengths, with 8 feet being the most common. This matches construction standards and helps reduce wastage.
What type of sawmills are used in Kenya?
In Kenya, sawmills are either:
Tractor-powered (PTO sawmills) used in forests
Stationary sawmills located in timber yards
PTO sawmills are more flexible and can operate directly where trees are cut.
Can sawmill operators deliver timber after cutting?
Yes, many sawmill operators offer delivery services after milling. In most cases, clients only need to cover fuel costs for transportation, especially if the work was done in the forest.
What happens to wood waste after milling?
Wood waste such as offcuts and sawdust is not wasted. It is usually used for:
Firewood
Charcoal production
Wood fuel
How can I avoid being overcharged at a sawmill?
To avoid overpaying:
Understand the cost per foot (KSh 7)
Know the timber sizes you want
Confirm measurements before cutting
Agree on pricing before milling begins
The base (trunk) of the tree produces the best and strongest timber because it is thicker. This section is ideal for cutting larger sizes like 4×2, while upper sections produce smaller sizes like 2×2.
