Born from the discomfort of "Why don't we wash our houses?" Cleaning service "Gaiheki Senka" that removes moss and mold without damaging homes proposes a new approach: "Don't paint."

What does it mean to wash exterior walls?

In the maintenance of detached houses, the solution to "visual stress" such as moss and mold on exterior walls has generally been a business model that leads to expensive renovations (exterior wall painting/repainting) costing hundreds of thousands to over a million yen.

Amidst this, "Gaiheki Senka" (operated by MFS Co., Ltd. / Grade Group Co., Ltd.) is focusing on a new option that dramatically restores the beauty of homes by "washing" them, rather than the conventional approach of "painting first."

With the concept of "homes that can be made beautiful just by washing," we propose an unprecedented exterior wall cleaning service that dramatically improves the appearance of homes at a significantly lower cost and shorter construction period compared to exterior wall painting.

Background of the Service's Birth

◉ The relationship between "appearance" and price seen from the experience of selling a car

The trigger was the service representative's own experience selling a car. After thoroughly cleaning and coating the car before selling it, the impression during appraisal clearly improved, and it was bought at a price the owner was satisfied with.

On the other hand, on another occasion, when the car was presented for appraisal with dirt on the exterior and a dull interior, the owner was told, "The price will be reduced due to dirt and signs of use," and was offered a lower amount than expected. At that time, the owner keenly felt the reality that "even with the same car, how it has been treated is judged by its appearance and reflected in its price."

◉ "Cars are washed, so why aren't houses washed?"

Through the car selling experience, the owner realized that "visual impression is directly linked to asset value." At the same time, looking around, they noticed that the exterior walls of many houses were left dirty. Especially in detached houses, it is not uncommon for moss and black stains on the exterior walls to be left as they are.

"Cars cost hundreds of thousands to millions of yen, while houses cost tens of millions.

Yet, cars are washed frequently, but the exterior walls of houses are hardly ever washed." "If the time comes to sell the house in the future, will it be undervalued simply because the exterior walls are dirty?" A question arose: could the sense of "gap between appearance and price" felt with cars also apply to houses?

◉ The idea of "washing exterior walls to protect asset value"

From these realizations, the idea emerged: "Shouldn't there be an option to wash the exterior walls of a house, just like a car, to protect its resale value?" In fact, in the real estate industry, the first impression of the exterior greatly influences the judgment of prospective buyers, and properties with clean exterior walls and approaches tend to be evaluated more highly than those that are not.

However, the reality is that even when people want to "clean their exterior walls," many estimates assume large-scale construction with scaffolding, making them hesitate due to the cost. Therefore, there was a strong need for an exterior wall cleaning service that would allow people to "wash it properly before selling" or "maintain the exterior regularly" with a more accessible approach.

3 Strengths and Differentiation Points of Gaiheki Senka

1. A new option: "Don't paint." In general housing renovations, it is common to assume that "dirty means it's time to repaint," leading to proposals for expensive painting work. However, we do not believe that all houses require repainting immediately. In reality, many cases appear old simply due to the accumulation of moss, mold, rain streaks, and exhaust stains, rather than deterioration of the coating itself. Gaiheki Senka proposes the option of "cleaning only" for such homes, rather than "painting first." Furthermore, Gaiheki Senka performs exterior wall cleaning "without scaffolding" by utilizing long lances and specialized equipment for high-altitude work. This significantly reduces the cost and time associated with scaffolding installation and removal compared to general painting work or cleaning that requires scaffolding. For those who think, "It's not time to paint yet, but I want to improve the appearance," or "Expensive renovations are difficult right now," or "I just want to improve the impression before selling or renting," Gaiheki Senka's ability to significantly improve the home's appearance for tens of thousands to hundreds of thousands of yen is a major feature. Moreover, with a stance of "not recommending unnecessary work," we are building a different position in the conventional exterior wall industry as an entity that identifies and proposes "maintenance truly needed for the current home," rather than just a renovation company.

2. Restoring beauty by focusing on "visual stress" rather than "coating deterioration." In the exterior wall industry, maintenance is generally discussed from specialized perspectives such as "waterproofing performance," "coating deterioration," and "durability." On the other hand, what homeowners actually worry about daily often includes "visual stress" such as:

・Greenish stains from moss and mold

・Black streaks from rain streaks

・Dullness on the north side

・Dirt from exhaust fumes

・The impression of the house looking "old." Gaiheki Senka focuses on restoring the original beauty of the exterior walls, aligning with the feeling that "the house just looks dirty." Furthermore, by making the appearance beautiful, it leads to psychological satisfaction for the homeowner, such as "improved impression from neighbors," "confidence when receiving guests," and "the entire building looks brighter." Gaiheki Senka is supported by many customers as "beauty maintenance" that not only removes dirt but also improves the feelings of those living there.

3. Exterior wall maintenance suited for "the coming era," responding to inherited real estate and vacant house issues. In recent years, due to the declining birthrate, aging population, and increase in vacant houses, there has been an increase in consultations such as "I inherited my parents' house" or "I'm struggling with what to do with a house that no longer has anyone to manage it."

However, for inherited homes, Gaiheki Senka offers a realistic and low-cost option of "first restoring beauty through cleaning" rather than "painting first," even for requests like:

・It's difficult to undertake renovations costing millions of yen immediately.

・We plan to sell, so we want to avoid large investments.

・We live far away and cannot manage it frequently.

・We want to at least tidy up the appearance first.

By carefully cleaning the dirt accumulated over the years, the impression of the building is greatly improved. Additionally, vacant houses can give an "unmanaged impression," leading to issues with crime prevention and neighborhood aesthetics. Gaiheki Senka contributes not only to improving appearance but also to creating the impression of a "well-maintained home." We will continue to support the increasing issues of inherited real estate and vacant houses as a "home maintenance partner."

4. "Reliable exterior wall maintenance" created by professional techniques and sincere service. At Gaiheki Senka, specialized staff focused on exterior wall cleaning handle the work. We propose the optimal cleaning method tailored to each house by carefully assessing the type of dirt and the condition of the exterior wall material.

For example, different types of dirt require different approaches:

・Moss and mold stains

・Black streaks from rain streaks

・Dirt from exhaust fumes

・Dullness accumulated over many years

Gaiheki Senka utilizes environmentally friendly professional cleaning agents that are less likely to damage exterior walls, based on extensive knowledge and experience, to maximize cleaning effectiveness. Furthermore, we provide sincere explanations based on the current situation regarding whether "cleaning alone is sufficient" or "repainting will be necessary in the future," without unnecessarily causing anxiety.

Additionally, as we value being a locally-based service, we have established a long-term support system that includes:

・Consultations on exterior wall maintenance

・Regular condition checks

・Consultations for recurring dirt

・Proposals for future maintenance

This "peace of mind and sincere service," rather than just "finishing the work," is why Gaiheki Senka is trusted by many customers.

Future Outlook

In the current housing maintenance industry, the idea that "dirt means immediate repainting" is becoming common. However, in reality, there are many cases where the beauty can be sufficiently restored by simply removing dirt from the coating itself.

Gaiheki Senka aims to contribute to the optimization of housing maintenance costs by identifying "maintenance truly needed for the current home," rather than recommending unnecessarily expensive work.

Furthermore, we will provide value as a "service that can improve the impression of a home at a low cost" for social issues that are predicted to increase, such as vacant house problems, management of inherited real estate, the burden of housing maintenance due to aging, and reform costs due to rising prices.

We aim to create a society where people can face their homes with peace of mind, not only by "making homes beautiful" but also by reducing the "exterior stress" and "anxiety about housing maintenance" felt by homeowners.
