Complete Demolition Services Across Sydney

Every demolition service delivered by our own licensed team. From initial asbestos assessment through to final site clearance.

01

Complete Building Demolition Services

Unsafe demolition practices lead to structural collapses, utility strikes, and serious injuries that could have been prevented with proper planning and execution. CMS Contracting specialises in complete building demolition from single-storey homes to multi-storey commercial complexes, using systematic demolition methods that prioritise safety whilst protecting neighbouring properties. Our experienced operators use modern demolition equipment and dust suppression systems to efficiently remove structures whilst managing noise, debris, and environmental impact according to Sydney council regulations. Choose our comprehensive demolition services to ensure your building is removed safely, legally, and without disruption to surrounding areas.

02

Selective Partial Demolition Services

Partial demolition requires surgical precision to remove specific sections without compromising the structural integrity of remaining buildings. CMS Contracting excels in selective demolition work including wall removals, room modifications, and structural alterations that demand expert knowledge of building construction and load-bearing elements. Our skilled team carefully assesses structural requirements and uses specialised techniques to modify buildings whilst maintaining safety and compliance with Australian building codes. Experience the precision that 20+ years of selective demolition expertise brings to your Sydney renovation or expansion project.

03

Concrete Breaking & Removal

Sydney’s reinforced concrete structures require specialised equipment and techniques that standard demolition methods cannot handle effectively. CMS Contracting provides comprehensive concrete demolition services using hydraulic breakers, diamond cutting equipment, and concrete crushing attachments to efficiently remove driveways, slabs, foundations, and reinforced structures. Our concrete breaking services include precise cutting for partial removals and complete demolition with material sorting for recycling and disposal. Overcome tough concrete demolition challenges with our specialised equipment and expert techniques that ensure efficient removal without damage to surrounding areas.

04

Complete Interior Strip-Out Services

Outdated interior strip-out methods create dust hazards, structural damage, and expensive cleanup that proper techniques easily prevent. CMS Contracting delivers comprehensive interior strip-out services for offices, retail spaces, and residential properties using systematic removal processes that protect building structure whilst efficiently clearing interior elements. Our experienced team handles everything from carpet and fixtures to suspended ceilings and partition walls, including safe removal of hazardous materials like asbestos when present. Transform your space efficiently with our professional strip-out services that prepare your Sydney property for renovation or new fit-out work.

05

Total Site Clearance & Clean-Up

Incomplete site clearance creates ongoing problems including pest issues, drainage problems, and council compliance violations that delay your construction project. CMS Contracting provides complete site clearance services including vegetation removal, debris cleanup, and underground obstacle removal using modern equipment and systematic clearing methods. Our comprehensive approach includes proper disposal of all materials, soil preparation, and final site cleanup that leaves your property ready for immediate construction work. Ensure your Sydney site is completely cleared and construction-ready with our thorough clearance and cleanup services.

06

Controlled Staged Demolition

Single-phase demolition disrupts business operations and creates unnecessary risks when buildings remain partially occupied during construction projects. CMS Contracting specialises in stage-by-stage demolition that allows continued operation of unaffected areas whilst systematically removing designated sections according to your project timeline. Our controlled dismantling methods minimise noise, dust, and disruption whilst maintaining strict safety barriers between active demolition zones and occupied areas. Maintain business continuity during your Sydney renovation project with our expertly managed staged demolition services.

07

Heritage Building Demolition Services

Heritage demolitions require specialised knowledge of conservation requirements and council regulations that standard demolition contractors cannot navigate properly. CMS Contracting provides delicate heritage demolition services with careful material salvage, documentation requirements, and compliance with heritage protection guidelines under expert supervision. Our experienced team works closely with heritage consultants and council authorities to ensure proper procedures whilst recovering valuable architectural elements for restoration or reuse. Protect Sydney’s architectural heritage whilst meeting your development needs with our specialised heritage demolition expertise.
