Asbestos has been widely used in schools, hospitals, residential, commercial and industrial buildings throughout most of the 19th century right up until the late 1980’s when the proper regulations that were put into place started to mitigate the risk effectively.
Asbestos is directly linked to various diseases but most notably mesothelioma, asbestosis, and lung cancer. This is why asbestos should always be removed by certified/trained professionals who know how to get the job done right and safe.
All Thomas James Environmental Inc. workers are fully trained and certified and carry the proper identifications on them throughout each project.
Here is a list of common building materials know to contain asbestos if installed prior to the mid-late 1980’s. That being said there should always be proper Designated Substance Report by a certified environmental consultant to confirm.

Moulds are a large and taxonomically diverse number of fungal species in which the growth of hyphae results in discoloration and a fuzzy appearance. Mould in the construction industry has a history of simply being a matter of time, indoor air quality/movement and of course the natural elements, although many technologies have been developed to mitigate or sometimes even eliminate the risk/growth of mould. If not treated properly mould can spread/grow quite quickly turning a small problem into a big one.
Mould growth in buildings can lead to a verity of health problems. Most commonly respiratory effects like asthma, coughing, headaches, and other physical symptoms. Proper removal of mould is necessary to stop the spread of mould throughout the space it is being removed from and the workers must be wearing the correct protection to protect themselves.

Mould can go un-noticed for several years depending on where its growing, here’s a list of places mould can sometimes grow whether it’s out in the open or not visible without investigation.

HVAC System Drain Pans
Terminal Units
Ceiling Tiles
Cavity Walls
Masonry Surfaces
Electrical Equipment
Paper – If stored in mould friendly conditions
Washrooms, shower units, saunas
Pool areas


Lead is added to paint to speed up drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion.
Exposure to lead is bad for your health and depending on what level of exposure, age and sex of the person exposed (pregnant women and children being at the highest level of risk) your symptoms may vary. Lead poisoning can cause anemia and impaired brain and nervous functions. Low levels of exposure to lead can cause learning disabilities and behavioural problems with children.
All Thomas James Environmental Inc. workers are fully trained and certified and carry the proper identifications on them throughout each project. We treat lead as a serious issue on construction projects and follow all written regulations and guidelines.
Lead was widely used throughout most 1900’s until regulations started to get more control over it’s usage in the 1980’s. Buildings painted before 1960 will most likely have lead paint, buildings painted between 1960 and 1990 may have lead paint and buildings painted after 1990 should not contain lead paint. There should always be a designated substance report written by a certified environmental consultant to confirm all hazardous materials in any case.

Dust (debris from old toys or paint)
Backyard or school playground (paint)
Children’s toys
Water pipes


Starting a project off right usually begins with a solid demolition team to remove any existing building materials, or buildings not needed to begin your new work. Hiring the right demolition team can often set the tone of a project and set up your schedule for the remainder of the project. Our hands on approach to project management along with skilled enthusiastic workers a just a couple of the ways we make sure every project gets off to the right start.
