Installing a shelf, repainting a wall, changing a floor: every small project starts with a trip to the store. The price of construction materials has changed significantly in recent years, and the final bill depends as much on the choice of tools as on the choice of materials. This quick guide reviews what really costs, what can wait, and what a rushed DIYer needs to know before pulling out the credit card.
Labeling of DIY materials: what the CLP regulation changes in store
Have you noticed new pictograms on your paint cans or wood glues? Since 2024, the revised European CLP regulation (Regulation (EU) 2023/2055, published in the Official Journal of the European Union on September 27, 2023) strengthens the labeling of certain chemical substances present in common DIY products.

In practical terms, manufacturers are reformulating their ranges to reduce volatile organic compounds (VOCs). “Low VOC” paints and glues often cost more than older formulations. This additional cost directly impacts the material budget of an interior renovation project, even a modest one.
To find practical advice on Maison Sublime, it’s best to compare technical data sheets before buying: a paint displaying the A+ label on the French health label remains the most readable reference for a consumer.

Reading the label takes thirty seconds. Ignoring the label can cost a round trip to the store when the product is not suitable for the surface.
Prices of wood, plaster, and insulation: persistent tensions since 2023
The Capeb, in its 2024 Materials Price Observatory (published in June 2024), notes a continued rise in insulation and wood products. Prices for insulation and wood remain on the rise, while some metals are stabilizing or slightly decreasing.
Why does this matter for a weekend DIYer? Because a drywall partition, insulating lining, or pine flooring are the most common items in a home improvement project. The budget can vary significantly from one quarter to another for the same basket of materials.
Choosing between solid wood and reconstituted panels
Solid wood (pine, fir, oak) is more affected by fluctuations than particle boards or MDF. For a shelf or a simple piece of furniture, a melamine panel does the job at a lower cost. Solid wood is justified when the piece remains visible and the finish matters.
A reconstituted panel costs significantly less than solid wood for an equivalent functional result in many interior projects. Stainless steel screws, on the other hand, have seen their prices relax: take advantage of this to not skimp on the quality of the fasteners.
Tools: buy smart rather than buy everything
Competing guides readily list dozens of tools. A rushed DIYer does not need to own everything from the first project. Three criteria allow for quickly filtering what deserves a new purchase, what can be borrowed, and what can wait.
- Frequency of use: a screwdriver, a tape measure, and a drill-driver are useful for almost all small jobs. They justify a quality purchase from the start.
- Project complexity: a circular saw or a laser level only pays off if you are laying a floor or putting up a partition. For occasional use, renting from a DIY store is much cheaper.
- Durability: a well-maintained hand tool (wrenches, pliers, hammer) lasts for decades. An entry-level power tool may fail after a few projects. It’s better to invest a little more in the drill and save on consumables.
Reuse and second-hand materials
Since 2023, platforms like Backacia have opened their spaces to the general public, and brands like Leroy Merlin (ADEO group) are developing reuse and the second life of products. Doors, tiles, sanitary ware: the second-hand market for construction materials is becoming structured and allows for reducing the bill while limiting waste.
The “systematic new” reflex is costly. Before ordering online, check the stock of reclaimed materials near you. The condition of the items is generally checked, and savings can reach a significant portion of the material budget.
Home renovation budget: items that DIYers underestimate
The visible materials (paint, flooring, lighting) capture all the attention. The forgotten items inflate the bill at the end of the project.
- Consumables: sanding discs, screw bits, rollers, protective tarps, masking tape. They often weigh as much as the main tool on a small project.
- Surface preparation: a filler, a primer, or a floor leveling compound represent a cost that many discover at the last minute.
- Safety: safety glasses, gloves, dust masks. Safety equipment costs little but avoids much heavier expenses.
Plan for a margin of about one-fifth of the material budget for these ancillary items. This buffer absorbs unexpected costs without turning the project into a source of stress.
Comparing prices between stores and online
Price differences for the same product vary greatly between a large DIY store, a professional trade open to individuals, and an online marketplace. For heavy materials (bags of cement, plasterboards), the delivery cost can negate the price advantage of the web. For screws, accessories, and lightweight tools, online ordering often remains competitive.
The best reflex is to prepare a complete list, then compare item by item. Twenty minutes of checking can significantly lower the overall bill, especially on a home improvement or interior renovation project that combines several types of materials.
