Commercial Interior Remodelling Is Where Most Projects Go Wrong
A commercial interior remodel sounds straightforward until you’re three weeks in and a trade hasn’t shown up, a permit submission is stalled, and the landlord is asking questions you don’t have answers to. The scope looked manageable on paper — some walls coming down, new flooring, updated lighting, a refreshed reception area — and somewhere between the first demo swing and the first inspection, it became a project management problem.
This is exactly the kind of work Silcon Construction was built for.
We’re a general contractor and project manager for commercial interior remodelling projects across the Greater Toronto Area. We take on the full scope — from initial site assessment through to final handover — and we own the coordination, so you don’t have to. That means managing every trade in the correct sequence, handling landlord and permit relationships, enforcing the schedule, and delivering a finished space that functions as intended.
Whether you’re a tenant reconfiguring a floor to match how your team actually operates, a landlord refreshing a unit between tenancies, or a property manager executing a capital improvement program across multiple suites, we bring the same structured approach: clear scope, realistic pricing, trade accountability, and a single contact who’s responsible for the outcome.
What Commercial Interior Clients
Tell Us Before They Call
"Our space no longer fits how we work, and we need to reconfigure it."
Businesses evolve, and the spaces they occupy often don’t keep pace. Open plans that need more privacy, private offices that need to open up, circulation paths that create daily friction, and storage areas that have taken over functional square footage. We assess how the space is being used versus how it needs to be used, and execute the reconfiguration — not just the construction.
"We've tried managing subcontractors ourselves, and it was a disaster."
Running a commercial interior remodel without a general contractor means you’re personally coordinating a framer, an electrician, a plumber, a flooring contractor, a painter, and a millwork shop — often without the leverage to hold any of them to a schedule. One late trade cascades into every subsequent trade. We take that coordination off your plate entirely.
"We're not sure what permits we need or how to get them."
Commercial interior remodels in Ontario frequently require building permits, and permit requirements can vary depending on the scope, occupancy classification, and municipality. We’ve navigated the permit process across multiple GTA municipalities, and we manage submissions, responses, and inspections so the permit process doesn’t become the reason your project stalls.
"Our landlord has requirements we need someone to manage on our behalf."
Commercial tenants renovating leased space often need landlord approval for construction drawings, trade credentials, insurance certificates, and site access protocols. Landlords and property managers have their own timelines and their own standards. We interface directly with your landlord, so you’re not caught in the middle of a back-and-forth that delays your project start.
"We got a quote that seemed reasonable and ended up paying significantly more."
Scope growth and hidden conditions are the two most common causes of cost overruns on commercial interior projects. We conduct a thorough site assessment before we quote, flag every condition that could affect the budget, and deliver a number that reflects the actual project. Change orders occur when the scope changes — not because we missed something during the walkthrough.
Commercial Interior Remodelling Services We Deliver
Space Reconfiguration
& Demising:
Removing or repositioning interior walls to change how a space is divided — opening up floor plates, creating new private offices or meeting rooms, splitting a single tenancy into multiple units, or combining adjacent suites into one. We frame, drywall, patch ceilings, reroute electrical circuits affected by the changes, and finish to a standard that makes the reconfiguration look intentional rather than improvised.
Full Interior Demolition
& Rebuild:
When the existing interior is beyond reconfiguration — wrong layout, inadequate infrastructure, finishes that have degraded beyond refreshing — we strip the space back to shell and rebuild it from the ground up. Demolition, debris removal, new framing, rough-ins, drywall, ceilings, flooring, finishes, and millwork, managed as a single coordinated scope from day one to handover.
Ceiling Systems:
Suspended T-bar grid ceilings, drywall bulkheads and coffered features, open exposed-structure finishes, and specialty acoustic ceiling systems. We coordinate ceiling installation with the mechanical and electrical trades so HVAC diffusers, sprinkler heads, light fixtures, and data cable runs are all accounted for before the grid goes up — not cut in as an afterthought.
Commercial
Flooring:
LVT, carpet tile, polished concrete, epoxy, hardwood, ceramic and large-format porcelain tile, and rubber flooring — specified and installed for the intended use, foot traffic load, and finish aesthetic of each zone within the space. We handle substrate preparation, transition details, and cove base installation to the standards required by the finish material and occupancy.
Framing &
Drywall:
Interior partition walls, curved or angled feature walls, shaft wall systems, and bulkhead framing — built square, plumb, and to the specifications your designer and structural drawings require. Drywall finishing to Level 4 or Level 5 as required by the paint and finish specification.
Millwork & Custom
Built-Ins:
Reception desks, boardroom credenzas, built-in storage walls, feature wall panels, display shelving, server room enclosures, and custom cabinetry of all types. We work from your millwork shop drawings and coordinate delivery and installation within the construction sequence so the space reads as designed rather than assembled in pieces.
Lighting & Electrical
Upgrades:
New circuit installation, panel upgrades, LED lighting retrofits, switching and dimming systems, data and communications rough-in, and electrical work required to support a reconfigured or upgraded interior. We manage the electrical subcontractor as part of the overall project — not as a separate engagement.
HVAC & Mechanical
Modifications:
Ductwork extensions and modifications for reconfigured spaces, new VAV or fan coil unit installations, thermostat zone reconfiguration, and exhaust and makeup air adjustments for new or modified rooms. We coordinate mechanical work in the correct sequence with respect to the ceiling and partition schedule so that the HVAC system serves the new layout properly.
Interior Painting
& Finishes:
Commercial-grade painting to match your finish schedule, feature-wall applications, epoxy and specialty coatings, and touch-up and protection programs for high-traffic areas. We coordinate painting within the construction sequence so the painted surfaces are protected from subsequent trades and delivered in a condition that doesn’t require remediation.
Landlord Enhancement & Suite
Turnover Work:
For property managers and landlords, we execute suite improvement and turnover scopes between tenancies — refreshing finishes, replacing flooring, updating lighting, repainting, and reconfiguring layouts to improve the space’s marketability for the next tenant. We work quickly, cleanly, and to a standard that justifies the lease rate the property commands.
Tenant Improvement Coordination:
For tenants entering a new lease and building out a space, we act as the site-level general contractor — executing the tenant improvement scope, coordinating with the landlord’s base building trades where the TI work interfaces with building systems, and delivering the space on schedule so the lease commencement date means something.
Why Commercial Tenants, Landlords, and Property Managers Choose Silcon in the GTA
Commercial interior remodelling involves more trades, more approvals, and more sequencing decisions than most clients expect going in. Silcon Construction functions as a true general contractor — we hold the trade contracts, enforce the schedule, manage the landlord relationship, and own the outcome. You don’t need to track five separate subcontractors or wonder who’s responsible when something isn’t right. We are.
Commercial remodelling projects in Ontario require building permits, inspection sign-offs, and adherence to both the Ontario Building Code and, where applicable, workplace safety requirements under the Occupational Health and Safety Act. We operate with documented safety programs and hold current registrations with ISNetworld and Avetta, which meet the contractor pre-qualification requirements imposed by many landlords and property managers before granting site access. Compliance is built into how we run projects, not retrofitted at the end.
We’ve built a reputation in the GTA commercial construction market on two things: quoting what we intend to charge and delivering what we commit to. That means thorough site assessments before numbers go out, change orders only when scope genuinely changes, and a dedicated site supervisor who manages daily progress and reports to you throughout the project. No surprises on the invoice. No silence mid-construction. Just consistent execution through to a finished space you’re satisfied with.

How a Commercial Interior Remodel with Silcon Works
Initial Contact
Call or email us with the basics: what the space is, what you’re trying to change, and what your timeline looks like. We’ll ask the right questions up front — including about your relationship with your landlord and any permit history for the space — so nothing catches us by surprise later.
Site Review
We walk the space thoroughly and assess the existing conditions — structural, mechanical, electrical, and finish. We look at what’s behind the walls and above the ceiling, not just what’s visible on the surface. If there are conditions that will affect the budget or the schedule, we surface them at this stage.
Pricing & Proposal
We prepare a detailed, line-item quote covering every phase of the scope, with a project schedule built around your occupancy or operational requirements. You’ll know exactly what each element costs and when it happens — no lump sums that obscure where the money is going.
Approval & Mobilization
Once the quote is approved, we coordinate permit submissions, order long-lead materials, schedule the trade sequence, and align the construction start with your landlord and building management. We mobilize prepared, not to assess the situation for the first time.
Managed Execution Through to Handover
A dedicated site supervisor manages the project daily — sequencing trades, managing progress against the schedule, communicating with building management, and reporting to you throughout. We coordinate every inspection, manage every deficiency, and hand over a space that is complete, clean, and ready to occupy.
