Building renewal requires careful planning, experienced trades, and clear communication. Dura Seal works alongside building envelope consultants, strata councils, and property managers to deliver repairs and renewal projects while managing the practical challenges of construction in occupied buildings.

01

General Contractor

One accountable team to manage your renewal project.

Dura Seal manages construction from mobilization through completion, coordinating labour, materials, subcontractors, site safety, and quality control to execute your consultant’s drawings and specifications.

For strata councils and property managers, this means a clear point of contact, coordinated scheduling, and communication about access, disruptions, and progress. For consultants, it means an experienced construction partner who respects the design, raises issues promptly, and follows through on site.

Construction Manager

Practical construction expertise, involved early.

As Construction Manager, Dura Seal helps owners and consultants plan how the work will be delivered. We contribute construction input on sequencing, site access, procurement, trade coordination, and budgeting before work begins.

During construction, we coordinate the work and provide visibility into costs, schedules, and decisions. This approach helps strata councils and property managers understand their options and make informed choices alongside their consulting team.

Property Maintenance & Repairs

Timely repairs that help protect your building.

Dura Seal provides targeted repairs and maintenance for building envelope and waterproofing systems, including sealants, windows and doors, roofing, cladding, and membranes.

We work with property managers and strata councils to address immediate concerns and coordinate work around residents and building operations. Where an issue requires further investigation or design, we collaborate with your building envelope consultant to establish the appropriate repair approach.

Discovery and Exploration

Help your consultant see what lies beneath the surface.

Understanding an existing building often requires opening assemblies to examine concealed conditions. Dura Seal supports consultant-led investigations with exploratory openings, selective removal, access arrangements, and reinstatement.

Our crews work alongside the consulting team to expose the areas they need to assess, protect surrounding finishes, and manage disruption to occupants. This work helps consultants develop repair recommendations grounded in the building’s actual condition.

Class D Budgets

Early cost guidance for better planning.

Before committing to a major renewal project, owners need an initial understanding of the potential investment. Dura Seal prepares preliminary Class D budgets based on the available assessment findings, proposed scope, and project information.

We help strata councils, property managers, and consultants explore options, prioritize work, and plan funding. We identify key assumptions and allowances so owners understand what the budget covers and how it may change as investigations and design progress.

Construction Project Financing

Help moving from a necessary project to a funded plan.

Building renewal can place significant financial demands on owners and strata communities. Dura Seal can help connect clients with financing providers to explore options for eligible repair and renewal projects.

Working with your property manager and consulting team, we can provide construction budgets and scheduling information to support those discussions. Financing remains subject to the provider’s assessment, approval, and terms.

Building Envelope Condition Assessments (BECA)

Leaks, aging materials, and recurring repairs can leave owners wondering how much work their building needs, and when. A Building Envelope Condition Assessment, carried out by a qualified consultant, helps establish the condition of exterior assemblies and identify priorities for repair or renewal.

Dura Seal supports the assessment with exploratory openings, access, selective removal, and reinstatement so your consultant can examine concealed conditions. We also provide practical construction input and preliminary budgets to help connect their recommendations with the realities of carrying out the work.

For strata councils and property managers, this provides a clearer basis for discussing scope, timing, and funding with your consulting team.

Since 1989, Dura Seal has worked alongside the building science community to deliver building envelope and waterproofing repairs and renewal. We understand that successful construction depends on respecting the design intent, following specifications, and communicating clearly when existing conditions require a decision.

We bring experienced site leadership, skilled trades, and coordinated project management to your projects. From investigation support and preliminary budgeting to mockups, construction, and closeout, we help maintain continuity between what is specified and what is built.

When unexpected conditions arise, we document what we find, bring practical options to the discussion, and work with your team on an approved path forward.

A building renewal project is a significant responsibility. Owners need to understand the investment, councils need reliable information to make decisions, and property managers need a contractor who can coordinate work around daily building operations.
