◇　When renovating, what should I pay attention to in the estimated cost? 　◇

When you receive a remodeling estimate, it’s crucial to pay close attention to its contents.

However, it’s not always clear what should take precedence.

In this column, we’ll delve into evaluating remodeling estimates, with a focus on key factors like price and specifications.

By correctly considering these elements, you can ensure the success of your remodeling project.

１　What should I check about the breakdown of renovation costs?

You will always receive a “estimate” when requesting renovation work.

The breakdown of the estimate shows how much the work will cost.

Each cost, such as “material cost,” “construction cost,” and “miscellaneous expenses,” is detailed.

You can see where and how much of what materials will be used, and how much they will cost.

It may be a good idea to check whether the number of materials (equipment/building materials), unit price, area, etc. match the renovation details, and if you have drawings, keep them handy and check them while looking at them.

If the technical terminology is difficult to understand, please check with the remodeling company you requested a quote from.

２　How much is the average renovation cost?

As an example of typical renovation costs,

・Toilet replacement cost: 100,000 to 300,000 yen

・System kitchen replacement cost: 600,000 yen~

・Unit bath replacement cost: 1 million yen~

・Room cloth and flooring replacement cost (approximately 10 tatami mats) 300,000 yen ~

This is a guideline, but the cost will vary depending on the grade of the product you choose.

If it is a full renovation, the average cost is 5 million to 15 million yen, assuming a 3LDK.

３　What is the difference between renovation costs for condominiums and detached houses?

～What is the cost of renovating an apartment? ～

Compared to detached houses, condominiums are relatively inexpensive to renovate.

In the case of condominium renovations, there are many cases where the cost is around 5 million yen.

In condominiums, the common areas such as exterior walls and exterior hallways cannot be renovated, so there are restrictions on what can be renovated. However, it can also be said that you can spend more money on the interior.

～How much does it cost to renovate a detached house? ～

Renovation costs for detached houses tend to be higher than for condominiums.

It often costs more to renovate the exterior as well, and if you only renovate the interior without renovating the exterior, the average cost is around 5 million yen to 10 million yen.

Renovation costs will vary depending on the number of rooms and the structure, such as 2-story or 3-story building.

Please note that depending on the scope and construction period of the renovation, whether it is an apartment or a detached house, you may not be able to live in the area, so you may need to arrange temporary housing.

Consider this cost when considering renovations.

4　 How to reduce renovation costs?

～Communicate your budget/Don’t be particular about the manufacturer～

“I thought the budget would be 1.5 million yen, but when I received the estimate, it was 1.8 million yen.”

In this case,

“Actually, I’m thinking of a budget of 1.5 million yen…Is there a way to stay within this amount?”

Let’s talk to the contractor who gave us the estimate and ask for advice.

They will probably make suggestions to help you stay within your budget, such as, “In that case, change the material to something like this…”

moreover,

If you are not picky about the manufacturer, there are cases where you can reduce costs by using cheaper equipment and materials without sacrificing quality or functionality, so tell the remodeling company your budget and if they have the product you want, they will replace it. Please ask if they have any items.
