The Importance of Comparing Estimates for Exterior Painting in Kawasaki City and Key Points to Consider!

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 costs, such as excessively thinning the paint or reducing the number of coats.

To avoid regrets with 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 questions like,

In this article, we will provide detailed explanations on points to know when getting estimates for exterior wall painting and important items and comparison points for 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 Kawasaki City can be used
5. Ensure that the scope of work is clearly defined
6. Check the details of warranties and after-support
7. Verify not only the exterior paint but also the paint for ancillary parts and the number of coats
8. Confirm if the paint is suitable for the substrate
9. Check if the painting plan considers the location and natural environment of Kawasaki 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 scope of work, the methods of construction and materials used can vary. Therefore, the costs can differ 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 notice if you are charged more than the market rate. By comparing multiple companies, you can understand the appropriate construction details and price range. However, rather than just looking at costs in competitive estimates, it is recommended to check the construction methods (number of coats and cleaning methods), as well as the track record and reviews, to make a comprehensive judgment!

If you proceed with a request without obtaining competitive estimates,

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

Some contractors may extremely dislike competitive estimates or pressure you to sign a contract quickly. Do not rush into a contract; obtain competitive estimates and take your time to consider based on the estimate details! 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 competitive 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 excessively high.

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

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

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

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

We recommend contractors that clearly state what costs are associated with what. Contractors who clarify the amounts will provide peace of mind for those requesting the work.

POINT 4 Check if you can use subsidies or grants from Kawasaki City

To reduce the cost of exterior wall painting work, make sure to check with the contractor whether you can use fire insurance or subsidies.

If the exterior wall is damaged due to a typhoon or flying objects, it may be covered under the fire insurance’s “wind damage” compensation. Additionally, if you are performing exterior wall insulation renovations at the same time as the exterior wall painting, you may be eligible for national or local government energy-saving subsidies.

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

POINT 5 Confirm that the details of the work are clear

When considering a quotation, it is essential to confirm “whether the construction content aligns with your objectives and requests?”

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

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

For instance, 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 lifespan or opting for partial repairs as one of the options. Similarly, if the renovation aims to improve heat insulation and you use a paint focused on aesthetics, the original purpose will not be fulfilled, rendering the work unnecessary.

Basically, the quotation will list the processes in order, so it is necessary to check in advance how the construction will proceed 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 warranties and after-support in advance, in case any issues arise after construction. Regarding warranties, be sure to check not only the warranty period but also the details 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 for auxiliary parts and the number of coats

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

There are three points to check:

• 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?

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

POINT 8 Confirm that the appropriate paint is used for the substrate

There are various types of exterior wall materials, and it is necessary to use paint suitable for each! In addition to ceramic siding, which is widely used in single-family homes, there are mortar, metal siding, ALC, and tiles, and the selection of primers (sealers, fillers, primers) changes depending on the substrate.

During the on-site survey, whether the contractor checks the type of existing exterior wall materials and the paint used in the previous coating is also a key point in distinguishing reliable contractors.

POINT 9 Confirm if the exterior painting plan considers the location and natural environment of Kawasaki City

Kawasaki City includes areas close to the sea, such as Kawasaki-ku, densely populated residential areas along the Tamagawa River, and highlands in the northern hilly regions that experience strong winds. Proximity to the sea may accelerate rust on metal parts and deterioration of the paint film due to salt air, and on sides that are close to neighboring houses and receive poor sunlight, moss, algae, and mold are more likely to occur, which affects the selection of paint (weather resistance, anti-algae, and anti-mold properties).

Be sure to check not only the cost but also whether the proposed paint and process are suitable for the building’s location! (Refer to the points to consider for exterior painting based on location in Kawasaki City as well.)

【Kawasaki City】Procedure for Exterior Painting Estimates

We will explain in detail the steps to request an estimate for exterior painting. Specifically, the process is as follows.

1. Search for contractors that serve Kawasaki City
2. Request an estimate
3. Have an on-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 serve Kawasaki City

Currently, most contractors have information available on the internet or on signs, so you can research there. When searching for contractors, aim to get multiple estimates and keep in mind the nine points mentioned earlier to reduce the chances of making a mistake.

When narrowing down several contractors from many options, it is recommended to read and refer to reviews on Google and other platforms, and to contact companies with good ratings. In doing so, it is important to look not only at the rating points but also at the number of reviews, posting dates, specificity of content, presence of施工 photos, and responses from the company, as this will give you insight into the actual service of that company.

STEP 2 Request a Quote

To narrow down quality contractors from exterior painting quotes, it is essential to request at least 3 companies. With only 1 or 2 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 a quote, have the contractor conduct a site survey. Since the contractor will come to your home, be sure to ask any questions you have regarding the construction 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)
• Is the construction done by their own staff?
• How will they manage the storage of materials, placement of scaffolding, and measures against washing water and paint splatter?
• If you have preferred paint or manufacturers, let them know
• Confirm the type of existing exterior wall materials, the paint used in the last painting, and the condition of the sealing

STEP 4 Compare Quotes

Once you have received quotes from multiple contractors, please compare the quotes from each company. The three key points to pay attention to are:

1. Check if the product names and manufacturers of the paint are listed
2. Check if the area (㎡) and unit prices are listed
3. Check if the processes and specifications (number of coats) are listed

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