For Those Struggling to Find a Consultation Desk for Large-Scale Repairs

Large-scale repairs for condominiums and apartments often involve multiple projects such as exterior walls, roofs, waterproofing, sealing, and metal parts, leading to many voices expressing, “I don’t know where to consult all at once.” Since the scope of work is broad, costs are significant, and consideration for residents and neighbors is necessary, choosing a contractor should be approached with caution.

Kakeru Koumuten Co., Ltd. is a construction company based in Aoba-ku, Yokohama, specializing in exterior renovations throughout Kanagawa and Tokyo. Since we can handle everything from temporary scaffolding to exterior painting, waterproofing, roofing, and rain gutters, you can plan the overall repairs of the building through a single point of contact. We welcome inquiries from owners, management companies, and corporate representatives.

This page summarizes the basic concepts of large-scale repairs and the benefits of consulting with Kakeru Koumuten, allowing you to proceed to regional guidance pages based on the location of the building. Please start by looking at the areas or types of work that interest you.

These are the main types of work that are often required for large-scale repairs. We will propose a combination of necessary areas based on the condition of the building and your budget. Since the feasibility and specifications differ for each building, we will explain after conducting an on-site survey.

Temporary Scaffolding

This is the installation of scaffolding, which serves as the foundation for the entire construction. It is planned according to the height and shape of the building. Click here for the costs and duration of scaffolding work

Exterior Wall Painting

Protection of the exterior walls and restoration of aesthetics. We select paint and processes according to the condition of the substrate. Click here for the costs of exterior wall painting plans

Sealing Work

Replacement and addition of sealing around joints and sashes. This process is closely related to waterproofing.

Roof and Balcony Waterproofing

Renovation of the waterproofing layer on roofs and balconies. It prevents water leakage into the building’s interior. Click here for the costs of waterproofing work

Roof Repair and Renovation

Repair, re-roofing, and roof overlay methods. We provide proposals according to the shape of the building. Click here for information on roofing work

Rain Gutter and Sheet Metal Work

Replacement and repair of rain gutters and sheet metal parts. Proper drainage of rainwater protects the building.

Exterior Wall Repair

Repair of cracks, bulges, and missing sections. This is also important as a substrate treatment before painting.

Common Area Repairs

We propose repairs based on the condition of common areas such as shared hallways and external stairs.

Interior and Restoration

We also accept consultations regarding interior finishing and restoration based on the condition of the building.

Other Building Repairs

For damages not listed above, we will first check the site and propose necessary repairs.

The availability, specifications, and materials used for construction may vary depending on the condition of the building. The above are examples of work typically carried out during large-scale renovations. The actual necessary work will be proposed after a site survey.

We can also provide guidance on the feasibility of repairs based on the location of the building and your desired construction details, even outside the listed areas.

Main Timing for Considering Large-scale Repairs

If you notice any of the following symptoms, it is time to consider large-scale or partial repairs. Delaying action may lead to further impacts on the interior of the building, so we recommend an early on-site inspection.

Cracks in the Exterior Walls Cracks can allow rainwater to enter, leading to internal deterioration.

Fading or Chalking of the Paint If touching the exterior walls leaves a white powder, it is a sign that the protective function of the paint has diminished.

Cracks or Peeling of Sealing If the sealing around joints or sashes breaks, it can become a pathway for rainwater intrusion.

Deterioration of Waterproofing on Rooftops and Balconies Blistering, cracking, or pooling of water in the waterproof layer are areas to check before they lead to leaks.

Water Leaks Water leaks in indoor or common areas require prompt investigation and action.

Rust on Iron Parts Rust on iron parts such as stairs, handrails, and doors can affect strength if it progresses.

Damage to Rain Gutters and Sheet Metal Cracks or disconnections in rain gutters, and lifting of sheet metal can lead to poor drainage of rainwater and damage to the building.

Time Since Last Renovation If a certain period has passed since the last renovation, it is a good time for inspection.

The appropriate timing for repairs varies significantly depending on the building’s specifications, location, materials used, and deterioration conditions. It cannot be uniformly determined as “every few years.” If you notice any concerning symptoms, we will assess the condition through an on-site inspection and provide recommendations.

Cost of Major Repairs

The cost of major repairs varies based on the size of the building, number of floors, scaffolding area, deterioration conditions, materials used, and scope of work. Even for the same “major repairs for a condominium,” the amount can differ significantly depending on the necessary work, so we cannot provide a uniform estimate for the total cost. The exact cost will be estimated after an on-site inspection.

Details about unit prices and pricing plans for each type of work can be found on the following pages of our official website.

Pages for Confirming Prices and Plans	Content
Construction Menu and Price List	Information on construction menus such as roof overlay (cover method) and the cost considerations.
Cost of Exterior Painting Plans	Information on costs for exterior painting and sealing work by plan.
Cost of Waterproofing Work	Information on cost considerations for waterproofing work.
Cost and Duration of Temporary Scaffolding Work	Information on the costs and estimated duration for temporary scaffolding.

For other types of work and the total cost of major repairs for the entire building, please confirm after an on-site inspection, as the conditions differ for each building. We do not publish unsubstantiated estimated total costs.

Subsidies and assistance programs vary by country, prefecture, and municipality in terms of content and application periods, and may be newly established, terminated, or have changed conditions from year to year. Eligibility depends on the building’s conditions and the program details at the time of application, so it is necessary to check the latest guidelines. We will check together if there are any applicable programs during our consultation.

Process Until Construction

This is the general flow from consultation to completion of construction and subsequent aftercare maintenance.

Please let us know the location of your building and any issues you are facing via phone, form, or non-face-to-face estimate.

On-Site Investigation

We will visit the building to check the condition of the exterior walls, roof, waterproofing, and metal parts.

Confirmation of Deterioration Status

Based on the investigation results, we will organize where and what kind of damage exists.

Submission of Repair Details and Estimate

We will provide the details and scope of the necessary work along with the estimate.

Discussion of Details

We will adjust the scope, specifications, and schedule based on your requests.

Contract

Once you are satisfied with the details, we will proceed to the contract.
