Merchants Renovation Essentials Tips & Advice

Moving house is a big project and the checklist always only seems to get longer. While homeowners diligently inspect their new homes for critical visible defects such as wall cracks or pipes leakage, one thing that is invisible but essential is often overlooked – indoor air quality (IAQ).

 “The quality of the air you’re breathing at home is just as important, if not more so, than the quality of your carpentry, flooring, painting or furniture,” says Zachery Tan, Certified IAQ Manager (CIAQM) and Business Director at Newway, an established local company that specialises in Air-Conditioning and Mechanical Ventilation (ACMV) and IAQ services for residential and commercial spaces.


Here are 5 common sources affecting the air quality in your new home:


  1. Furniture and Cabinetry

New furnishing and finishes can release harmful chemicals (volatile organic compounds) into the air for years through a process called off-gassing.  Excessive concentration of volatile organic compounds (VOCs) can have adverse health effects – long-term exposure to VOC vapours can cause eye, nose, and throat irritation; headaches and loss of coordination; nausea; and damage to the liver, kidneys, or central nervous system. For example, formaldehyde is a colourless, flammable, strong-smelling chemical that is used in resins (i.e., glues) found in manufactured wood products such as desks, beds, cabinets, and more.


  1. Paint

Many paints contain VOCs; the fumes from a fresh coat of paint may cause symptoms including lung irritation, headache, dizziness, and vision problems. Some people may experience more symptoms than others depending on their level of exposure and any prior health conditions.


  1. Flooring

Vinyl is a popular flooring option in Singapore homes due to it being budget-friendly, durable and low-maintenance. However, most vinyl flooring, made from reprocessed plastic, contained toxic phthalates, lead, cadmium, brominated flame retardants, and other toxic chemicals – these chemicals can contribute to indoor air pollution by drifting out of the flooring and into the air and dust inside homes. In addition, certain laminate flooring is found to contain high levels of formaldehyde.


    4. Moulds

    Moulds produce allergens, irritants, and in some cases, potentially toxic substances (mycotoxins). Mould can cause detrimental health effects, especially for children or people with pre-existing health conditions. Asthma is the most common health issue associated with long-term indoor mould exposure.


    5. Air Conditioners

    If the air in your home is polluted with VOCs and allergens, your air conditioner is likely worsening the situation. Also, if the air conditioner is poorly maintained, for example if it is leaking any excess fluid or has more condensation than usual, it may be harming your indoor air quality as well.


    Hence, to safeguard your family’s health and ensuring an optimum living space, it is essential to have professionals like Newway to perform an indoor air quality assessment before moving in.
