Renovation construction

For buildings too, good health is most beautiful.

Regardless of the size of construction, we carry it out sincerely with consideration for customers’ needs. At times, we may even propose or discuss construction or other methods that differ from customers’ requests, as deemed appropriate from a professional point of view. This is because we want our customers to maintain the economic value of their assets long into the future. The satisfaction of our customers is the proof of our technical and solution abilities, and this is driven by our emphasis on the quality of construction work.

Project support (planning, proposals, adjustments, negotiations)

・Drafting and implementing medium- to long-term maintenance plans
・Various types of construction work involved with changes to office layouts
・Handling negotiations and submittal of notices with regard to building owners,

　tenants, authorities, and others
・Management and supervision of construction related to each of the above activities

We offer reliable prior checking of finishing together with test construction.

Test construction enables customers to check in advance, with their own eyes, the degree of results and their finish. Once the customer is satisfied, we arrange matters such as work schedules and plans to meet their needs.

Maintenance of stone materials: Restoration

Restoring the inherent beauty of the materials.

Exposed to rain, dust, exhaust fumes, ultraviolet rays, and other environmental conditions, the stone materials at the entrance to a building and on its exterior walls—the building’s face—are susceptible not only to surface soiling but also to material wear, which can have a negative impact on their durability.

They also “breathe” through fine pores on their surfaces, invisible to the naked eye. With the passage of years, the oil and water that enters these pores can stain the materials.

As highly delicate materials, they need optimal treatment reflecting their wear and soiling conditions as well as the years since they were installed and other considerations.

Restoring the inherent shine of the materials and securing both beauty and safety helps a building to make a more favorable impression on visitors and protects its asset value. We can respond flexibly to customer needs in areas such as work scheduling and methods.

You can rest assured that our professional diagnostics and techniques will generate surprising results.

・Special maintenance for marble, granite, etc.
　--Restorative polishing (restores the shine of the materials)
　--Stain and rust removal
　--Repairing scratches and cuts

Partial stain removal can make the cleaned area stand out compared to the rest of the surface—opposite the intended effect. We deliver proposals and restoration work based on consideration of the overall finish, in harmony with the building image.

Restorative polishing of stone. The shine of the material was restored to 93% after polishing, compared to 28% before.

Removing tenacious rust beneath signs and steel plates left in place for years.

Spray-painted graffiti is a true nuisance and an eyesore. Leaving it as it is could even lead to a worsening of public safety in the neighborhood.

High-temperature pressure cleaning

Cleaning of various exterior materials:

Demonstrating outstanding cleaning results on various building materials.

We can clean not only floors but also walls, shutters, and other places where soiling has occurred, using specialized high-pressure cleaning equipment that employs the correct temperature and detergent for the material and the extent of soiling. High-temperature pressure cleaning demonstrates outstanding cleaning performance while having little impact on the material itself.

・Building exterior finishing materials:

　Tile, stone, metal panels, coating, etc.
・Perimeter area: Floors, planters, etc.

We remove not only soiling but also gravel, moss, and other unsightly materials.
