The ten most common questions asked by individuals about small everyday jobs

Travaux.com, the leading platform connecting individuals with building professionals, has offered the "Ask a Professional" service for several years. Today, the site reveals the 10 most frequently asked questions from its users. From unclogging a toilet to knowing how long to let a wall dry before painting, these questions illustrate the small challenges of everyday life.

"Maintaining and furnishing one's home often raises questions - sometimes surprising ones - but most have a simple answer. Even the most common incidents, such as a blocked toilet or a faulty smoke detector, can be unsettling when you encounter them for the first time."

The internet can provide reliable solutions, but when in doubt, consulting a professional remains the best option.

Here are the 10 most frequently asked questions on Travaux.com:

How to unclog a toilet?

Fortunately, this problem is often easy to solve, especially with a plunger, available from €3. Place it in the toilet bowl and make up-and-down movements, gradually increasing the force. This should allow the water to flow and the clog to break up. If this doesn't work, the blockage may be further down the pipes—in which case you'll need to call a professional.

Can you lay tiles over existing tiles?

It's technically feasible, but strongly discouraged by professionals. It adds weight to the surface, potentially weakening the walls or floors. Furthermore, it increases the risk of water infiltration due to gaps between the tiles. Removing the old tiles takes more time, but avoids damage... and additional costs in the long run.

How do you bleed a radiator?

Start by turning it off and wait for it to cool completely. Get a container and a cloth. Using a radiator key, a flathead screwdriver, or even a coin, open the bleed screw (counterclockwise) until you hear a hissing sound: that's the air escaping. When the water starts to flow, close the screw. Tip: always start with the radiators on the ground floor before moving upstairs.

How long should you let plaster dry before painting?

Depending on the surface area and ambient conditions (heat, humidity), drying can take from a few days to four weeks. The plaster changes color, turning from dark brown to salmon pink, indicating that it is dry. Before painting, apply a "primer" (a mixture of 30% water and 70% paint) to prevent the paint from peeling. Apply two primer coats, then two topcoats.

How do I change the doors on my kitchen cabinets?

Simply changing the doors and handles is a cost-effective way to modernize a kitchen. Start by measuring the doors: they should be 3 mm smaller than the cabinet fronts to open easily. Unscrew the hinges (starting from the bottom), then drill the new doors in the same locations. Attach the hinges, reattach them to the cabinets, and adjust the doors. Finish by drilling the holes for the handles.

Can ventilation grilles be installed above double-glazed windows?

It's possible, provided the top of the frame is wide enough. On some older windows, this can be a problem. In that case, you'll need to carefully drill through the frame to install the grilles. If the task seems complicated, it's best to call in a professional.

Should you use glossy or satin paint for baseboards and doors?

It depends on the desired finish, but also on the paint's durability and gloss. The glossier the paint, the more durable it is, as it contains more resin. For baseboards, which are subject to impacts, professionals recommend a high-gloss (gloss) or satin (semi-gloss) lacquer.

Is an underlayer equivalent to a layer of mist?

No. While the undercoat can serve a similar purpose, the two products are different. The thicker undercoat is designed for hard surfaces like wood. The undercoat, on the other hand, is a diluted paint, ideal for helping the topcoat adhere well to a freshly plastered wall.

Can a placo partition wall be moved?

Technically, yes. But in practice, removing a partition wall without damaging the walls or ceiling is tricky. It then requires plastering, painting, and possibly permits depending on the situation. It is therefore strongly advised to hire a professional.

Can you lay a new laminate floor over an old one?

This is strongly discouraged. Layering two pieces of laminate can create an inconvenient thickness that makes it difficult to open doors or install appliances. It's best to remove the old flooring to avoid future problems.
