Visual inspection and moisture readings
We carry out a thorough on-site assessment to find every affected area, including the ones that are not visible to the naked eye.

Verdun’s duplexes and triplexes, most of them built before 1960, combine very specific risk factors: poor ventilation, repeated water infiltration and high rental density, all of which encourage mould to spread through basements, walls and attics. Gestion Réno Solution takes charge of every step of the process, from the initial on-site assessment through to the certificate of compliance, without you having to coordinate several trades. Entrusting your mould decontamination in Verdun to a specialist team with more than 12 years of expertise protects your occupants’ health and preserves the value of your building.

The borough of Verdun holds a concentration of older housing stock whose construction materials and ventilation systems were never designed for today’s airtightness standards, which creates ideal conditions for mould to develop. The proximity of the St. Lawrence River amplifies condensation, above all in multi-household dwellings where humidity management is often neglected.
When carrying out a mould decontamination in Verdun, indoor air quality in duplexes has to be taken into account from the inspection onward, so the problem does not return after treatment. For buildings where asbestos might also be present, see our residential and commercial asbestos removal expertise.

The Verdun borough by-law on the sanitary condition of dwellings explicitly prohibits the presence of mould and requires every owner to correct the source of humidity behind the problem. That legal obligation gives real urgency to any mould treatment in Verdun, since a failure can expose the owner to penalties and jeopardise a property transaction.
For complete, documented handling, see our residential and commercial mould decontamination service, which covers rental blocks as readily as single-family homes with mould decontamination in Verdun.

Decontamination eliminates the existing mould colonies and cleans the contaminated surfaces, but without active humidity control the risk of recurrence remains very real in Verdun’s older buildings.
Remediating a damp basement is therefore not limited to removing visible mould: it must be accompanied by lasting preventive measures so that mould decontamination in Verdun stays effective over the long term.
To counter excess humidity at the source, see our dehumidification solutions for preventing mould from returning in your dwelling or your building.

Every building has its particulars, and our approach adapts to the reality of Verdun’s buildings for a lasting result. Here is what our handling includes:
We carry out a thorough on-site assessment to find every affected area, including the ones that are not visible to the naked eye.
Before any removal, we isolate the affected spaces so spores cannot spread into the rest of the unit or the building.
Our technicians completely eliminate the mould colonies using approved products, following the protocols in force in Quebec.
Adjoining surfaces that are not contaminated get a protective treatment to reduce the risk of the mould returning in the following weeks.
At the end of the work we hand over complete documentation attesting that the building meets the standards, useful for owners in the context of a sale or a lease.
With more than 12 years of experience and an RBQ licence in good standing, we have developed a structured method that applies as readily to damp basements as to the poorly ventilated attics of older buildings. Calling on our services for a mould decontamination in Verdun means documented handling, without your presence on site being necessary on the day of the work. See our safe residential demolition service if materials must be removed before or after the decontamination.
