Teamwork
Working closely with your professionals.
A major project is designed by several people. We work hand in hand with engineers, architects and technologists — yours, or those we recommend — so that what is drawn can be built, and what is built is compliant.
01
Engineers
Structure, foundations, soil. We build from their plans and report the real conditions on site.
02
Architects
Design, integration, details. We validate constructability and budget before the plans are final.
03
Technologists
Construction drawings and permit files. We give them the measurements and constraints of the existing building.
Are you an engineer, architect or technologist looking for a reliable contractor for your clients?
Let's talk about your next mandateSound familiar?
A major project should not keep you up at night.
01
The contractor who never calls back
Three messages, no reply. You learn how the job is going by driving past it.
02
The price that keeps growing
A one-page quote, then “extras” that pile up week after week.
03
The schedule that keeps stretching
Trades crossing paths without coordination, and an end date that keeps moving.
04
Nobody answers for the whole
The architect, the framer, the installer: each has a part, nobody has the overall view.
One partner for all four.

FAQ
Frequently asked questions
A question that is not here? Write to us — we reply within one business day.
What services does Gestion A.F. Construction offer?
Seven services: structure, exterior siding, project management, high-end work, additions, complex renovation and commercial renovation. We take on complete residential and commercial projects rather than small isolated jobs.
How do I get a price for my project?
Through the online estimate: you describe your project, attach photos or plans if you have them, and receive a detailed budget range right away. It is a conditional order of magnitude; the firm quote comes afterwards, following a site visit.
Which areas do you serve?
Lanaudière and Montreal's North Shore: Terrebonne, Mascouche, Repentigny, L'Assomption, Joliette, Rawdon, Chertsey, Saint-Calixte, Saint-Lin–Laurentides, Saint-Côme, Blainville and the surrounding area.
Do you work with engineers, architects and technologists?
Yes, closely. We build from their plans, validate constructability with them and report real site conditions. If you do not have a professional yet, we can recommend one.
Are you RBQ licensed?
Yes: RBQ licence 5806-1391-01, active and verifiable in the licence holders' registry of the Régie du bâtiment du Québec.
Do you offer service in English?
Yes. We are happy to discuss your project, visit the site and prepare your documents in English or in French.
Can the price change during the work?
Our estimate is detailed, item by item. If something major and unexpected appears when a wall or the ground is opened, it is documented, discussed and approved with you before any work is done.
