Causes of Mould in Buildings
Calgary’s ASTRA Restorations specializes in mould remediation. We have the expertise, certified training, experience, and specialty equipment to safely restore your residential, commercial, or industrial property so that it is once again safe for your family, your tenants, or your employees.
Never remove toxic mould yourself. Knowing how to recognize mould and how it enters your property, however, is essential to mould prevention and to knowing when to contact an expert.
Mould exists in the natural environment, and we contact it daily. Mould becomes problematic when its spores colonize the buildings we live and work in. They do this by attaching themselves to damp and water-damaged surfaces, especially in humid spaces with little air circulation.
Buildings affected by flooding and other water damage provide the perfect environment for mould spores to colonize. Burst pipes, sprinkler-head failures, plumbing issues, roof penetrations, or even small leaks can lead to serious health hazards, quickly and later.
Mould problems are not always easily seen. Mould can be found behind walls, under floorboards, and in other hard-to-see places. Even hidden, mould will still seriously affect air quality. The use of improper building materials and poor ventilation can leave some environments particularly susceptible.
Moulds are especially successful at colonizing damp drywall and wallpaper. They can flourish in office towers where water damage may not be a priority. Once established, mould spores will spread throughout the building, including through ventilation systems.
Extensive flooding in Calgary and Alberta left homes, commercial spaces, and warehouses water-damaged. If you suspect mould in your home or workplace environment, contact Calgary’s ASTRA Restorations right away.
ASTRA Restorations works hard, expertly, and efficiently, to restore your home, commercial, or industrial property so that you can breathe safe.
*ASTRA Restorations provides mould remediation free of cost with every water-damage restoration service. Calgary’s ASTRA Restorations has the expertise and the tools to save you health, time, money, and future hassle.

Project Description:
This project was performed with moderate-risk protocols (AAAM Section 5.3, with modifications by a registered occupational hygienist tailored to site conditions and to keep risk of asbestos exposures as low as possible). Excavators removed soil around a 120-foot long transite pipe. Once the pipe was fully exposed, ASTRA marked break areas for easier transportation to the City of Calgary’s asbestos-waste-disposal site.
ASTRA conducted a cleanup of the pipe’s outer surface and applied sealant glue to prevent fibres from being released into the air during cutting. The pipe was broken at set locations to minimize dust. Barriers kept unprotected workers away from the cutting zone. ASTRA Restorations’ registered occupational hygienist monitored the project and generated a final clearance report within one week of project completion.

Project Description:
ASTRA Restoration completed abatement of asbestos-containing exterior stucco of 28 townhouses owned by the Calgary Housing Corporation. We removed the stucco with moderate-risk protocols (AAAM 5.3). ASTRA created partial containments of less than 100 square feet in size, which we fitted with HEPA-filtered-negative-air units. Removal activity was performed mostly by hand tools. Collected abatement material was double bagged and disposed of as asbestos waste. Workers wore half-face respirators with P100 filters and disposable coveralls.
Abatement work was conducted by certified asbestos workers. Work was supervised by a certified hygienist. ASTRA’s certified hygienist daily monitored the removal worker’s personal air and collected air samples from outside the containment structure to check for environmental contamination. He also provided clearance reports to ensure proper abatement procedures.
