Commercial Renovation Specialists

Audy Construction is a commercial renovation contractor based in Mont-Saint-Hilaire, serving Greater Montreal and the South Shore.

We work with building owners, property management firms, general contractors, and real estate developers who need a reliable execution partner — a team that shows up, manages the site, communicates clearly, and delivers a clean result. Our projects range from full building envelope retrofits to phased window replacement programs across occupied buildings, coordinated to minimize disruption at every stage.

Services

What We Do

Specialized commercial renovation services for building owners, property managers, and developers who demand results.

Project Management & Coordination

For complex, multi-phase mandates, we offer dedicated project management services. Our coordinators handle scheduling, subcontractor oversight, municipal permitting, site safety, and client communication — giving building owners and property managers a single point of accountability from start to finish.

Window & Door Replacement — Large Buildings

Our core expertise. We manage window and door replacement programs across multi-storey residential buildings, office complexes, institutional facilities, and mixed-use developments. From product specification and procurement to phased installation across occupied floors, we handle every aspect of the mandate with the coordination and professionalism large-scale projects require. We work with leading manufacturers including Novatech and our trusted supplier network to source the right products for every building type and budget envelope.

Building Envelope Renovation

A building's envelope is its first line of defense. We plan and execute comprehensive envelope renovation projects — integrating new fenestration, exterior cladding upgrades, and air-sealing improvements into a single, coordinated scope. The result is a building that performs better, looks better, and retains its value over the long term.

Exterior Cladding — Commercial

We install and replace exterior cladding on commercial and multi-unit buildings, working with materials selected for durability, thermal performance, and visual impact. Whether you're refreshing an aging facade or undertaking a full re-cladding program, our team manages the project from permitting through final inspection.

Commercial Door Systems

From high-traffic entrance systems to fire-rated interior doors, we supply and install commercial door systems that meet code requirements and stand up to daily use. We coordinate with architects, building managers, and general contractors to ensure seamless integration into new construction and renovation projects.

Commercial Additions & Structural Work

When your building needs more space or a structural upgrade, we bring the same level of coordination and professionalism we apply to our fenestration programs. We work on commercial additions, interior structural modifications, and phased renovation programs for occupied buildings — with project management that keeps timelines on track and stakeholders informed.

FAQs

Answering your questions

Answering your questions

Have a specific project in mind? Let's talk scope.

What types of buildings do you work on?

We primarily work on commercial buildings, multi-unit residential buildings (condominiums, rental towers, co-ownership properties), mixed-use developments, and institutional facilities. Our focus is on mandates that require structured project management, phased execution, and technical expertise — not standard single-unit residential renovations.

Do you handle the full window replacement process, from product selection to installation?

Yes, entirely. We manage product specification in collaboration with the building owner or manager, procurement through our established supplier network (including Novatech and other certified manufacturers), permit applications, site coordination, phased installation scheduling, and final compliance documentation. You have one point of contact for the entire mandate.

Can you work on occupied buildings without disrupting tenants or operations?

This is one of our core competencies. We develop detailed phased plans to minimize disruption to residents, tenants, and business operations throughout the project. Our teams are experienced in coordinating around occupancy schedules, and we maintain clear communication with building management and occupants at every stage.

Do you handle municipal permits and regulatory compliance?

Yes. We manage all necessary permit applications and ensure full compliance with municipal building codes and energy performance regulations applicable to your project. This includes coordination with inspectors and final permit closeout documentation.

What is the typical timeline for a large window replacement program?

Timelines depend on the scale of the building, the number of openings, and whether the project is phased across occupied floors. A mid-size building program typically runs 8 to 16 weeks. Larger or multi-building programs may be structured across two construction seasons. We provide a detailed schedule as part of our initial proposal.

Do you work with general contractors and developers, or only directly with building owners?

Both. We work directly with building owners and property management companies, and we also operate as a specialized subcontractor for general contractors and developers on larger construction and renovation projects. We're comfortable in either role.

How do I get a quote for my building?

Contact us with the basic details of your project — building type, location, approximate number of openings, and timeline. We'll arrange a site visit, assess the scope, and provide a detailed written proposal. There's no obligation, and we move quickly.
