Most of you have questioned their sanity. As you approach Thika level 5 Hospital, the sound of nails being hammered into woods rents the air.
On arrival, competing posters greet you. Ready-made coffins are also glued to the makeshift shanties. This is the Kimilili coffin makers territory.
On a Friday afternoon, I meet Paul Ngang'a, 32. He has been making coffins since 2009.
"I loved woodwork from a young age, I also admired coffins," the graduate of Makuyu Don Bosco says.
The competition in making coffins is so high here in Thika but Ngang'a and co-workers appreciate that saying most people have come to appreciate this work.
The Kimilili coffin makers ground is dotted by a row of different funeral services. The graduate of carpentry skills goes on with his work with so much ease.
"Last year I opened my own funeral service, Jasho United funeral service." he points to where it is seated. A hearse rolls in to collect a coffin.
Passerbys often throw blunt stares, a diet they are accustomed to but Ngang'a maintains it is their way of giving back to the community.
"Death is for God, we are happy when working but we are not happy when people die. We sell every day. I love this work because it helps me to meet my basic needs." the staunch Christian affirms.
The least expensive coffin is 5000/=, minimum coffins cost 25-30K and the expensive ones have skyrocketing prices of 60,000/=.
"I see them like woods put together, they are coffins only when purchased and at work," he adds with a poker-faced smile.
The sun is their biggest challenge since they work in an open place. With time, they learned on how to deal with mockery. Other times, the dead do not fit the coffin hence they make a new one in a cut-price. A coffin goes by 22 inches to 6 and a half feet.
"Making coffins is not emotional neither are coffins a symbol of fear." he says.
In 5 years time Ngang'a plans to have a showroom for coffins and 2 hearses for transport services.
"Be proud of where you work, confront your fears and do not mind what naysayers say," said Ng'ang'a.
