Damp Diagnosis & Mold Remediation Service – Toronto and GTA

InteriorEra is expert in Mold Remediation

Interior Era are one of the Canada’s leading experts in diagnosing the causes of damp and condensation, which can lead to mold, combining a full diagnostic process with a plan for remedial action, along with a programme to eradicate the mold problem.

Insurers, homeowners, landlords and tenants can all benefit from the comprehensive service offered by Interior Era.

Mold is classed as a category one risk to health, as assessed under the Housing Health and Safety Rating System 2000, which is the same class as asbestos. The Environmental Protection Act (1990) classifies mold as a statutory nuisance that must be treated.

The Interior Era incorporates a 3 level process when considering Damp and Condensation issues in any property


Interior Era’s fully experienced technical team will then carry out a survey on the property, to identify possible causes of damp penetration and condensation inside the property. They will check for the following:


MInternally, the Interior Era technicians will check for visible damp conditions and evidence of mold contamination.

Damp and mold will often be concealed within the building structure – for example in cavities, under floorboards and behind skirting boards.

Wherever mold is evident, there is usually much more of it hidden within the building structure. We employ a wide range of sophisticated technical equipment to identify and analyse the contamination in these hidden areas, such as Endoscopes and Bore scopes with attached Inspection cameras which allow a detailed internal visual inspection in hard to access areas, without major disruption or damage to the building and its contents/decor.

General state of repair of the property – evidence of poor maintenance, often the source of water ingress and penetration into a property, including:

  • Brickwork, rendering & mortar
  • Roof – condition of roof tiles or flat roofs
  • Downpipes & guttering
  • Flashing around chimney stacks and in adjoining elements
  • Damp proof membrane – any evidence of missing, breached or faulty DPM
  • Waste pipes
  • Outside doors
  • Window units (paying particular attention to double glazed units and any lack of ventilation)
  • Air bricks – check for blockages
  • Measurement of moisture, humidity and temperature in all building materials with hi tech measurement equipment. This will confirm the conditions in the property as either damp and at risk of mold contamination, or dry and comfortable living conditions.

Picture opposite demonstrates moisture readings being taken which will determine the remedial action required.

Remedial Action

Following the survey a full report will be issued to the landlord, homeowner, plumber or other instructing party, which will provide a complete analysis of the causes of damp and mold, and a course of remedial action will be proposed which will eradicate the problem. Upon approval of the summary of works Rainbow will commence the treatment, which depending upon the nature and severity of the damp and mold will include the following treatments:

  • Washing, spraying or fogging of the affected areas with an appropriate anti-microbial will sanitise the contaminated surfaces
  • Removal of plaster and wood where contamination is severe or dry/wet rot has taken hold
  • Air Manager – an air sterilisation unit which will kill all airborne spores released from mold infestation can be deployed if necessary
  • Monitoring of drying regime – to guarantee suitable damp free conditions are maintained
  • Installation of appropriate ventilation systems (if appropriate)
  • Stripping out and replacing of units and building materials that have been affected beyond repair by the damp or mold
  • Redecorating following cleaning and sanitisation
  • Sign off/handover – following treatment and drying of property, a certificate will be issued which will confirm the home is conducive to a healthy living environment and is free from damp and mold
