Profile: Caswell Environmental Services Ltd. is a provider of asbestos removal, de-contamination, remediation, and construction services. We can guide through the current legal requirements, and take care of any abatement work from investigative work to encapsulation, removal, decontamination, and disposal. At our facility, we cover all aspects of the Brownfield remediation process; from initial site investigation through to the controlled transfer of contaminated waste, together with the demolition and clearing of land. A refurbishment and demolition survey is needed before any refurbishment or demolition work is carried out. This type of survey is used to locate and describe, as far as reasonably practicable.
