Have You Recently Felt That Renovation Costs Are Getting More Expensive?
Recently, we’ve been receiving more inquiries regarding exterior painting, roofing work, and interior renovations such as:
“It feels like the estimate is higher than last year.”
“I was told the delivery time is taking longer.”
“Is it true that some materials are unavailable?”
At the moment, the construction industry is being heavily affected by what is often referred to as the “Naphtha Shock,” causing significant price increases and supply instability for many renovation materials.
Even around Yokosuka City, various projects including exterior painting, roof repairs, interior remodeling, and water-related renovations are beginning to experience these impacts.
[Yokosuka Exterior Painting Price Increase] Building Materials & Paint Prices to Rise From June 2026
Due to rising crude oil prices, increasing naphtha costs, and higher transportation expenses, the construction industry continues to face ongoing price revisions for many building materials.
In particular, from June 2026 onward, price increases are expected for:
Exterior wall paints
Sealants / caulking materials
Waterproofing materials
Adhesives
Resin-based construction materials
Various interior finishing materials
As a result, renovation costs overall are beginning to rise.
Additionally, some materials are experiencing temporary shortages and delivery delays, leading to situations such as:
“Construction cannot begin immediately.”
“The new estimate is more expensive than before.”
“The delivery date for the product is still undecided.”
So, What Exactly Is “Naphtha”?
ナフサとは、石油から作られる原料の一つです。
It is used as a primary ingredient in many renovation and construction products, including:
Paints
Adhesives
Waterproofing materials
Sealants
PVC products
Insulation materials
Resin-based building materials
In other words, when naphtha prices rise, the costs of many renovation materials also tend to increase.
On top of that, the industry is currently being affected by:
Rising crude oil prices
Global instability
Increased shipping costs
Weak Japanese yen
All of these factors are contributing to continued construction material price increases.
Renovation Materials That Are Currently Rising in Price
Exterior Painting & Roofing Materials
Silicone paints
Inorganic paints
Heat-resistant paints
Sealants / caulking
Primers
Waterproofing materials
Some paint manufacturers have already increased prices multiple times within a short period.
Interior Renovation Materials
Wallpaper adhesives
Cushion flooring
Floor tiles
Construction adhesives
Gypsum board materials
Especially resin-based products are heavily affected, causing not only price increases but also delivery delays.
Water-Related Equipment
Kitchens
Unit bathrooms
Washstands / vanity units
Water heaters
Depending on the product and timing, some equipment may require waiting periods of several weeks to several months.
“Waiting Longer” Could Become Risky
In the construction industry, once material prices rise, they rarely go back down.
In the past, events such as:
The Wood Shock
Semiconductor shortages
Crude oil price surges
have all caused price increases that remained high afterward.
Especially for exterior painting and roofing projects, paint prices have a major impact on total costs.
It’s becoming increasingly common for customers to find that:
“The estimate became more expensive after waiting a few months.”
