[Yokohama City] Exterior Painting Estimate | Cost Average and Comparison Points for Multiple Estimates

When obtaining competitive estimates, while it is certainly better if the costs are low, deciding on a contractor based solely on the estimate cost can also be dangerous. This is because there are many ways to cut corners to keep costs down, such as excessively thinning the paint or reducing the number of coats.

To avoid regrets in exterior wall painting work, it is essential to obtain competitive estimates and carefully consider them. To confidently request painting work, it is crucial to identify a trustworthy contractor.

That said, among those who are requesting exterior wall painting work for the first time, there are likely many who have

such questions. Therefore, in this article, we will provide a detailed explanation of points to know when getting estimates for exterior wall painting and important items and comparison points in actual exterior wall painting estimates.

9 Points to Know When Getting an Estimate

When getting an estimate for exterior painting, there are nine main points to keep in mind.

1. Obtain estimates from three or more companies and compare them
2. Check if the contents of the estimate differ too much from other companies
3. Carefully check if there is a breakdown of materials and types
4. Confirm if insurance or subsidies from Yokohama City can be used
5. Ensure that the details of the work are clear
6. Check the warranty and after-support details
7. Verify not only the exterior paint but also the paint for auxiliary parts and the number of coats
8. Confirm if the paint is suitable for the substrate
9. Check if the exterior painting plan considers the location and natural environment in Yokohama City

We will explain each point in detail!

POINT 1 Obtain estimates from three or more companies and compare them

As mentioned earlier, the most important thing in exterior painting work is obtaining estimates. Obtaining estimates means requesting quotes from multiple contractors and comparing them.

There are many painting contractors, and even for the same work, the methods of construction and materials used can differ. Therefore, the costs can vary significantly depending on the contractor you choose.

Even if the request details are the same, if you decide based on only one estimate, you may not realize that you are being charged more than the market rate. By comparing multiple companies, you can understand the appropriate construction details and price range. However, it is recommended to not only look at the costs in comparative estimates but also to check the construction methods (number of coats and cleaning methods), track record, and reviews to make a comprehensive judgment!

If you proceed without obtaining comparative estimates,

the likelihood of regret increases, so we at Kakeru Koumuten recommend obtaining comparative estimates to all our customers.

Some contractors may extremely dislike comparative estimates or pressure you to sign a contract quickly. Do not rush into a contract; take your time to obtain comparative estimates and think carefully based on the estimate contents! If you already have estimates from other companies, we also accept non-face-to-face rough estimates based on other companies’ estimates and drawings.

POINT 2 Check if the contents of the estimate differ too much from other companies

When obtaining comparative estimates, it is also important to check if the contents differ too much from other companies. It is not uncommon for the construction area to be extremely large or the amount to be too high.

While it is not necessarily bad to have significant differences in amounts or construction details, make sure to confirm with the contractor the clear reasons for the differences from other companies.

POINT 3 Confirm if there is a breakdown of materials and quantities

When you receive an estimate for exterior wall painting from a contractor, be sure to check whether a breakdown is included.

Some contractors may only list quantities as “one set”, but this does not clarify what is being charged for what. If the quantities are unclear, the contractor can freely adjust the amounts, increasing the likelihood of additional charges.

We recommend contractors that specify what is being charged for and how much. Contractors who clarify the amounts will provide peace of mind for those requesting the work.

POINT 4 Check if insurance or subsidies can be used

To reduce the cost of exterior wall painting work, it is advisable to check with the contractor whether fire insurance or subsidies can be utilized.

If the exterior wall is damaged due to a typhoon or flying objects, it may be covered under the “wind damage” compensation of fire insurance. Additionally, if you are conducting insulation renovations of the exterior wall simultaneously with exterior wall painting, you may be eligible for energy-saving subsidies from the national or local government.

Using grants or subsidies requires separate procedures. Before obtaining a quote, please check if there are any applicable programs!

POINT 5 Confirm that the details of the work are clear

When considering the estimate, it is necessary to confirm whether the work details align with your objectives and requests.

“I plan to demolish the house or move in 10 years.”
“I want to change the design and color.”
“I am considering exterior painting due to fading and cracks.”
“The interior is hot, so I want to improve heat insulation.”

These are some of the reasons or concerns that may lead you to consider exterior painting.

For example, if you have decided to move or demolish in 10 years, using a highly durable paint with a lifespan of nearly 20 years would be a waste of money. It is necessary to consider using a lower-cost paint with a shorter durability or performing partial repairs as one of the options. Similarly, if you are renovating to improve heat insulation and use aesthetically focused paint, the original purpose will not be fulfilled, and the work will be wasted.

Basically, the estimate will list the processes in order, so it is necessary to check in advance how the work will progress and to confirm any uncertainties with the contractor.

POINT 6 Check the contents of the warranty and after-support

It is recommended to choose a contractor who explains the warranty and after-support in advance in case any issues arise after construction. Regarding the warranty, be sure to check not only the warranty period but also the contents of the warranty!

How long is the warranty period? What kind of after-support is available? Let’s confirm these details at the time of the estimate.

POINT 7 Check not only the exterior paint but also the paint and number of coats for auxiliary parts

When performing exterior painting, it is common to also paint the auxiliary parts. Auxiliary parts refer to “rain gutters, eaves, water drainage, fascia boards, nose boards, awnings, etc.”, and each has different materials. The materials include “wood, metal, calcium silicate, etc.”, and the type of primer used also varies.

The three points to confirm are as follows:

• Is the rank of the auxiliary part paint at the desired level? (Silicone, fluorine, etc.)
• What type of primer is used for the auxiliary parts?
• How many coats will be applied?

Make sure to check what paint is being used for the auxiliary parts as well as the exterior paint!

POINT 8 Confirm that the optimal paint for the substrate is being used

There are various types of exterior wall materials, and it is necessary to use paint suitable for each! In single-family homes in Yokohama, the most common is ceramic siding, along with mortar, metal siding, ALC, and tiles, and the selection of primer materials (sealer, filler, primer) changes depending on the substrate.

During the on-site survey, whether the contractor checks the type of existing exterior wall material and the paint used in the previous painting is also a point to distinguish a reliable contractor.

POINT 9 Check the exterior painting plan considering the location and natural environment in Yokohama

In Yokohama, there are areas close to the sea, such as Isogo-ku and Kanazawa-ku, regions where humidity tends to accumulate like valleys and northern slopes, and elevated areas exposed to strong winds. Being close to the sea may accelerate rust on metal parts and deterioration of the paint film due to sea breezes, and on the poorly sunlit northern side, moss, algae, and mold are likely to occur, which affects the selection of paint (weather resistance, anti-algae, and anti-mold properties).

It’s important to confirm not only the cost but also whether the proposed paint and process are suitable for the building’s location! (Please also refer to the points to consider for exterior painting based on locations in Yokohama)

【Yokohama】Procedure for Exterior Painting Estimates

We will explain in detail the procedure for requesting an estimate for exterior painting. Specifically, it will be carried out in the following steps.

1. Search for contractors that operate in Yokohama
2. Request an estimate
3. Have a site survey conducted
4. Compare the estimates

Most contractors will generally provide this service for free, but it’s a good idea to confirm whether there will be any costs involved just to be safe!

STEP 1 Research contractors that operate in Yokohama

Currently, most contractors have information available on the internet or on signboards, so you can research there. When searching for contractors, it’s advisable to look for multiple contractors with the intention of getting comparative estimates. By keeping the nine points mentioned earlier in mind, the likelihood of making a mistake decreases.

When narrowing down from the many contractors, it’s recommended to read Google reviews carefully for reference and to contact companies with good ratings. In doing so, consider not only the rating points but also the number of reviews, posting dates, specificity of content, presence of construction photos, and responses from the company to get a clearer picture of the actual service provided by that company.

STEP 2 Request an estimate

To narrow down excellent contractors for exterior wall painting estimates, it is essential to request at least three companies. With only one or two companies, it becomes difficult to compare the details, increasing the likelihood of not finding a quality contractor.

STEP 3 Have a site survey conducted

Once you have requested an estimate, the contractor will conduct a site survey. Since the contractor will come to your home, be sure to ask any questions you have about the work at that time. Examples of things you might want to ask or convey include:

• Communicate your requests and future life plans (how many years you plan to live there, whether you want to change colors)
• Whether the work will be done by their own staff
• How they will manage the storage of materials, scaffolding placement, and measures to prevent the splattering of washing water and paint
• If you have preferred paint or manufacturers, let them know
• Confirm the type of existing exterior wall materials, the paint used in the last job, and the condition of the sealing

STEP 4 Compare estimates

After receiving estimates from multiple contractors, please compare each company’s estimates. The three main points to pay attention to are:

1. Check if the product name and manufacturer name of the paint are listed
2. Check if the area (㎡) and unit price are listed
3. Check if the process and specifications (number of coats) are listed

If you request Kakeru Koumuten Co., Ltd., you can check the flow from inquiry to on-site investigation, estimate, construction start, and completion on the flow of construction page.

Exterior Painting Estimate | Comparison Points by Process

We will explain the processes and items that must be confirmed in an exterior painting estimate in order. If any of the items explained here are not included in the estimate, we recommend confirming with the contractor whether they are part of the work!

*For exterior painting work, it is generally necessary to install temporary scaffolding and mesh sheets for safety and to prevent debris from scattering to neighboring areas. Conditions may vary depending on the shape of the building and the scope of work, so we will omit the mention of scaffolding in the subsequent processes.

Knowing “approximately how much it will cost” makes it easier to determine whether an estimate is high or low. Here, we will introduce the price per square meter by plan listed in Kakeru Koumuten’s construction menu, rather than general online market prices.

Reference Estimate Example: 33.24 tsubo, exterior painting area 149.5㎡, using Silicone REVO1000-IR + high-durability sealing for a total of ¥940,000 including tax (including temporary scaffolding and painting of auxiliary parts, a reference example from the construction menu).

*The above is the price per ㎡ listed in Kakeru Koumuten’s Exterior Painting Construction Menu. The cost for temporary scaffolding is generally around ¥110,000 to ¥130,000 for a typical two-story house, but it may vary depending on building shape, area, road conditions, elevation, and horizontal transport. The amount may vary based on building shape, exterior wall area, substrate repairs, sealing quantity, auxiliary parts, and delivery conditions, so please confirm the exact amount after a site survey.

Regional Characteristics to Keep in Mind for Exterior Wall Painting in Yokohama

Yokohama City has 18 wards with a population of approximately 3.77 million. It is characterized by a complex terrain of hills, plateaus, lowlands, and reclaimed land, with many slopes and valleys. The climate is humid, making it easy for moss and algae to develop on exterior walls. In Typhoon No. 15 in 2019, the Yokohama Local Meteorological Observatory recorded the highest instantaneous wind speed in its history, causing significant damage to many homes in the city. When comparing estimates, be sure to check if the paint and specifications are suitable for the location of your home.
