What are the risks of post-construction cleaning during Ottawa's spring allergy season?

Post-construction cleaning during spring allergy season can create a double air quality problem for anyone with allergies or respiratory sensitivities. Spring tree pollen outdoors, combined with the fine construction dust and residue that cleaning stirs up indoors, can make symptoms noticeably worse for sensitive people.

The core issue is combined exposure. Fine dust from drywall, concrete and grout can include very small particles that are easily breathed in, and pollen adds to the load. Someone who normally manages spring allergies well may find cleanup week much harder, simply because there is more in the air than usual.

There are several practical ways to reduce the risk. First, keep windows and doors closed during interior post-construction cleaning in spring, even though ventilation is often recommended at other times. Slightly slower drying is a reasonable trade-off for keeping pollen out of a space that is being cleaned. Run HEPA-filtered air scrubbers during the cleaning; they capture construction dust and any pollen already inside, and can make a real difference to indoor air quality during the work.

Second, plan the dustiest and outdoor tasks thoughtfully. Local pollen forecasts can help you time exterior work like washing or window cleaning for days when pollen is less of a problem, and damp conditions tend to keep both pollen and dust down.

Third, anyone with known allergies or asthma should stay out of the home during post-construction cleaning if possible. That is good advice year-round, but especially in allergy season. Cleaning crews should wear suitable respirators for fine dust — ask the company what they use. After the cleaning, run the HVAC system with a good-quality filter for a while before allergy-sensitive people return, and consider duct cleaning as a final step if dust may have got into the ductwork, so it is not blown back into the house every time the system runs.

If anyone in the household has a medical condition affected by dust, ask their doctor about precautions before the work starts. You can find cleaning companies through the Ottawa Construction Network directory at justynrookcontracting.com; ask each one how they control dust on spring jobs.
