The renovation of projects can actually worsen your home, as when mold suddenly appears after renovation. Even if your house had never had mold before and you put a lot of new materials there, mold can suddenly arise after a house renovation project for various reasons. This makes it crucial to monitor your entrepreneurs (or your own DIY work) during the project to make sure you do not transform your home into an ideal reproduction ground for post-renovation mold.

Inadequate ventilation

The older houses are often quite “fleeing” when it comes to air. They are difficult to heat and cool in part because your air controlled by the climate continues to flee into the world, and they allow allergens and the dirt to infiltrate your living space. Thus, when people plan an intestinal renovation, they often seek to make the house as hermetic as possible – which is not a bad idea in itself. But you should make sure that the house has adequate ventilation, or that the airtight seal traps moisture in the house, and this additional humidity will almost always lead to growth in mold.

Renovated bathrooms can be a specific concern. Bathrooms are naturally damp rooms, and almost always require a correctly calibrated ventilation fan to remove the humidity from the space. Not only should the fan be the right capacity for the size of the room, but it must be executed long enough after each shower to ensure that the dry part (some models have an integrated humidity sensor which will trigger the fan each time the parts become wet), and it must be evacuated outside the house, not in the attic or the walls.

Water intrusion

If your renovation plan meant that an area of ​​your home was exposed to elements – windows, roofs or doors – there may be a given water intrusion. This is normal for extended, and harmless renovations as long as your entrepreneur took the time to dry the place before closing the walls and the floors. It does not require strong precipitation inside the house to sow the seeds of a humidity problem of weeks or months on the road – just let a space become marshy, then seal it is all that is needed.

Wetlands

Incidents will occur during renovations, including plumbing emergencies, water spills and drainage problems. As long as the problem is solved and it was an isolated incident, these types of accidents are not a big problem, but they can lead to wetlands on the walls, ceilings and soils that must be treated. Gifying a layer of primer on a damp stain on your wall does nothing to avoid mold, and can even encourage it because the sealing of this wet stain prevents humidity from evaporating.

You should also not assume that the water stains of a repaired leakage accident are only slightly slightly. Covering water stains on a wall with cabinets or paint without making sure they are completely dry is a disaster recipe. Conclusion: All wetlands must be dried carefully before being covered, regardless of their little one or the discretion they could be.

Moonnous wood

Sometimes you can do everything properly in terms of construction practices while bringing mold in the house, using moldy or even humid materials. It is not because you buy your wood, your dry partitions and other renovation materials does not mean that they are clean and without mold, especially if they are stored outside for a while. If the framing wood used to create your walls or the joists supporting the new floors enter the house that is too wet, they become reproductive grounds for mold once they have been sealed behind dry partitions or sub-floration. And dry partitions are porous and can easily absorb humidity while seeing superficially clean.

It is essential that all these materials are inspected before installation – both visually (for visible signs of mold) and using a humidity counter without pin. Wood must show a humidity reading of about 6%.

Wet dryer

The wet drywall is an almost perfect host for mold, so make sure that all the dry partitions installed during your renovation have a humidity reading of 0.5% or less and shows no sign of visible molding. This is particularly crucial if the dry partition was delivered and left to sit outside; Even if it is not raining or if the dry partition is covered, it can absorb humidity from the air. Printing and paint on dry damp partitions will look good for a while, but this trapped humidity will ultimately give mold spores everything they need to cultivate.

CVC disturbance

An unexpected way for a renovation project can cause mold infestation implies your CVC system, even if you do nothing. CVC systems are often disturbed during renovations – products must be far from the path, temporarily deleted recordings, temporarily moved compressors. And this can be a problem because mold can develop in unteashed CVC conduits, and everything that is jostling and the movement can disturb it, releasing spores which then circulate throughout the house when everything is connected. If these spores are blown in a wetland – like a badly ventilated bathroom – the finalera with pleasure.

It is always a good idea to think about cleaning after a renovation to ensure that dust and debris do not afflict you once the workers have disappeared – and in -depth cleaning of the conduits of your CVC system should be part of this plan, even if they have not been directly affected by the project.
