Points and Precautions to Compare When Getting Multiple Estimates for Roof Renovation in Kawasaki City!

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 for the first time, there are likely many who have questions like,

Therefore, in this article, we will explain in detail the points to know when getting an estimate for exterior wall painting and the 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 used
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 auxiliary parts and the number of coats
8. Check if the paint is suitable for the substrate
9. Confirm if the exterior 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 and materials used can vary greatly. 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 a quote from only one company, you may not notice if you are charged more than the market rate. By comparing multiple companies, you can understand the appropriate construction content and price range. However, it is recommended to not only look at the costs in competitive quotes but also to check the construction methods (number of coats and cleaning methods), performance, and reviews to make a comprehensive judgment!

If you proceed with a request without obtaining competitive quotes,

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

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

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

When obtaining competitive quotes, 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.

It is not necessarily wrong for there to be significant differences in amounts or construction content, but be sure to confirm with the contractor the clear reasons why it differs from other companies.

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

When you receive a quote for exterior wall painting from a contractor, be sure to check whether a breakdown is provided.

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

We recommend contractors that specify what and how much money is being spent. 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 conducting insulation renovations of the exterior wall simultaneously with the exterior wall painting, you may be eligible for energy-saving subsidies from the national or local government.

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 quote, it is essential to confirm “Is the construction content aligned with the purpose and requests?”

“I plan to demolish the house or move within 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 example, if you have decided to move or demolish within 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 goal of the renovation is to improve heat insulation and thermal resistance due to heat, using a paint focused on aesthetics would not fulfill the original purpose, rendering the work unnecessary.

Basically, the quote will list the processes in order, so it is necessary to check in advance how the construction will proceed and to confirm with the contractor if there are any uncertainties.

POINT 6 Confirm the contents of the warranty and after-sales support

It is recommended to choose a contractor who explains warranties 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 details of the warranty!

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

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

When painting the exterior walls, it is common to also paint the ancillary parts. Ancillary parts refer to “rain gutters, eaves, water drainage, fascia boards, nose boards, awnings, etc.” Each has different materials. The materials include “wood, metal, calcium silicate, etc.” and the types of undercoating also vary.

The three points to check are as follows:

• Is the rank of the ancillary paint at the desired level? (Silicone, fluorine, etc.)
• What type of undercoating material is used for the ancillary parts?
• How many coats are applied?

Be sure to check what kind of ancillary paint is being used, not just 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 addition to the widely used ceramic siding for houses, there are also mortar, metal siding, ALC, and tiles, and the selection of undercoating materials (sealer, filler, primer) varies depending on the substrate.

During the on-site inspection, whether the contractor checks the type of existing exterior wall materials and the paint used in the last coating is also a point to distinguish a reliable contractor.

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 Ward, densely populated residential areas along the Tamagawa River, and highlands in the northern hilly regions that are exposed to strong winds. Being near the sea may accelerate rust on metal parts and deterioration of the paint film due to sea breezes, and on sides with poor sunlight due to proximity to neighboring houses, moss, algae, and mold are likely to occur, which affects the selection of paint (durability, 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 by location in Kawasaki City as well.)

【Kawasaki City】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 serve Kawasaki City
2. Request an estimate
3. Have an on-site inspection 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 signboards, so you can research there. When searching for contractors, aim to get multiple estimates, keeping in mind the nine points mentioned earlier to reduce the likelihood of mistakes.

When narrowing down several contractors from the many available, it is recommended to read and reference 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 construction photos, and responses from the company, as this will give you insight into the actual service provided by the company.

STEP 2 Request a Quote

To narrow down quality contractors from exterior painting quotes, it is essential to request quotes from 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 Inspection

After requesting a quote, have the contractor conduct a site inspection. Since the contractor will come to your home, be sure to ask any questions you have about 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)
• Whether the construction will be done by their own team
• How they will handle the placement of materials, scaffolding, and measures against splashing of washing water or paint
• If you have preferred paint or manufacturers, let them know
• Confirm the type of existing exterior wall material, the paint used in the last job, 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 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, you can check the flow from inquiry to on-site survey, estimate, start of work, and completion on the Construction Flow page.
