Our Follow-through Service

One of the factors that make customers anxious about renovation is the follow-through service after the work is completed, isn’t it?
We often hear that the response was good until the end of the construction, but after that it was hard to get in touch with them and they didn’t respond well.
Here is an explanation of the follow-through service provided by Kakerukoumuten!

1.Photographing the construction process

1.Photographing the construction process
We provide before and after photos and step-by-step photos so that you can check the construction details anytime after completion.
You will be able to see if the work has been done properly through the photos.

2.Inspection after completion of construction

We will inspect the construction area at an appropriate time after construction
to check the condition of the constructed roof and exterior walls.
This allows us to understand the condition of the roof, which is usually difficult to see.
We can also respond quickly to natural disasters such as typhoons, earthquakes, and sudden leaks.
In addition to the manufacturer’s product warranty, we also offer a warranty for each of our projects.

The real relationship begins after the construction is finished.

At Kakerukoumuten, we believe that our real relationship with our customers begins after the construction is complete!
We look forward to working with you for many years to come.
