Hello!
This is Yamanaka from Kakeru Koumuten Co., Ltd., a specialist in roofing, exterior wall painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
This is a case study of an exterior renovation in Sumida-ku, Tokyo.
There are several types of exterior renovations, but this involves replacing the exterior wall (from mortar to galvalume steel sheet)!

・Inquiry Details

・The exterior wall is crumbling, and I’m in trouble…

・It’s a warehouse, so I want to keep costs low…

・It might be too late, but I want someone to take a look…

We received such inquiries!
When we actually visited the site for an inspection, we found that the mortar on the exterior wall was peeling and had fallen off in several places…
Since the exterior wall mortar is thick and heavy, it could cause a disaster if it fell on someone.
This time, since the underlying structure was also weakened, we proposed replacing it with lightweight, rust-resistant, and cost-effective galvalume steel sheet!

On this page, we will explain the actual results of the work done by Kakeru Koumuten!

Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.

Exterior wall replacement construction procedure

1. Demolition of existing exterior wall (mortar)

outer wall dismantling

The existing outer wall was in a state of collapse. First, we will set up scaffolding and dismantle the outer wall mortar. We must dismantle it gradually to prevent the outer wall from peeling off all at once, so we proceed with caution, prioritizing safety.

2. New Sheathing Installation (Softwood Plywood)

After dismantling the outer wall, we will install softwood plywood all over. This will be the sheathing installation.

3. Waterproof Paper Installation and Custom Metal Work

We will apply waterproof paper all over. Unlike the waterproof paper for roofs, the one for outer walls is made thinner. The custom metal work will be processed and installed on the eaves and corners. This custom metal work will also be made of Galvalume steel!

4. Main Construction (Galvalume Steel Wave Roofing)

We will proceed with the installation of wave roofing. We will secure it using specialized fasteners. This time, considering wind resistance, we have attached the fasteners at shorter spans!

5. Cleaning Up and Completion!

This time, we used inexpensive blue corrugated metal, so we intentionally proposed black for the fittings (corner joints, edge trims, and eaves)! I was a bit worried since I suggested it and left it to you, but you were delighted, saying, “It turned out cooler than I expected!!”
