Most home theatres here go into a basement that's already drywalled, painted, and trimmed, and nobody wants it gutted to run cable. We work inside the finished room: fishing wire through existing joist bays, using closets and mechanical rooms as chases, and patching every access point to disappear before we leave.

Working In A Finished Room
How do you wire a home theatre into an already-finished Aurora basement?
We route new cable through the cavities that already exist: joist bays above a drywalled ceiling, the stud bay behind a closet, the chase beside a furnace or water heater. A stud finder and an endoscope camera tell us what's inside the wall before anyone touches a saw, so the finished basement stays finished.
Every retrofit starts with figuring out what's inside the walls, not just what's in the room. We check ceiling height, joist direction, and where the ductwork runs before we recommend a speaker layout, because a plan that ignores the framing turns into a change order halfway through. That's the real difference between quoting a finished basement and quoting an empty stud bay: half the information is invisible until we open something to check.
Surround Layouts
5.1, 7.1, or 7.1.4 layouts fitted to a room that's already built. Speaker positions get chosen from what the existing framing allows, not from a diagram drawn before anyone opened a wall.
4K Projection & Display
Ceiling-mounted 4K laser projector with fixed-frame or motorised screen for dedicated cinema rooms, or wall-mounted 85- to 98-inch display for media rooms with ambient light. Dolby Vision calibrated on the final pass.
In-Wall Speaker Installation
Cable gets fished through existing joist bays and stud cavities, routed via a nearby closet or mechanical room where a straight chase already exists. A small access cut beats a long blind fish when a run won't cooperate.
AV Rack & Structured Wiring
The rack sits wherever the room already has power and airflow, often a mechanical room or existing closet doing double duty. Every run gets labelled at both ends, so a future service call doesn't mean opening a wall to trace a cable.
Control4 & Lutron Integration
Single-button scenes for the room: display on, projector lift down, shades closed, lights down, receiver in surround mode. Control4 home automation programmed in-house, then extended to adjoining zones.
Acoustic Treatment & Calibration
Bass traps and first-reflection panels go where the room's actual dimensions call for them, not a stock diagram. Final calibration sets speaker angles, crossovers, and bass management by ear and meter, not a factory auto-EQ.
Deliverables typically include a 5.1, 7.1, or 7.1.4 surround layout with in-wall and in-ceiling speakers; a projector and screen or a wall-mounted display with wiring concealed inside the existing walls; a labelled rack; and bass traps or absorption panels sized to the room, plus a final calibration pass. Every drywall patch from the cable pulls gets mudded, sanded, and primer-matched to the existing wall before we leave, so the access points disappear. Whole-floor audio in adjoining zones can run from the same rack, typically through our Sonos installation workflow in Aurora.
Pricing is itemised on the written estimate, and equipment can be supplied by us or by you. The same team handles every stage, from the first walkthrough to final calibration, so nobody outside our own crew touches the finished room.
The Access Question
What happens on-site when the Aurora basement is already finished?
When the room is already drywalled and trimmed, most of the work happens without anyone seeing a stud. We check the cavities first, run cable through the routes that already exist, and patch every access point before the final coat of paint goes on. Most retrofit theatres in an already-finished basement close in two to four working days across one or two visits. New-build pre-wire is a separate half-day visit coordinated with your contractor before drywall closes.
01
Site Assessment
We check what's actually behind the existing drywall: joist direction, ductwork, wiring already in the wall, and whether a nearby closet or mechanical room gives us a clean chase to the rack.
02
Written Design
Speaker positions, cable routes, and every planned access cut get documented in a single itemised proposal, so you see exactly where we're opening drywall before anyone picks up a saw.
03
Fishing The Cable
HDMI 2.1, speaker cable, and Cat6 get pulled through existing joist bays and stud cavities with fish tape, checked first with an endoscope camera on any run we can't see the end of.
04
Installation
Display mounted flush or projector and screen aligned to spec. Every drywall patch from the wiring pulls gets mudded and sanded flush before the rack goes live.
05
Calibration
Manual calibration with measurement gear tunes speaker angles, bass crossover, and display targets for the room as it was actually built, not a generic factory preset.
Handoff includes a full walkthrough, a household member trained on the remote or Control4 keypad, and a written record of every setting. Post-install support covers the small things that come up later: reconfiguring inputs after a new console arrives, retuning after a furniture change, or extending the system into a second zone. The same technician who opened your walls is the one who answers the phone afterward. Wiring sits cleanly alongside our structured network installation in Aurora for households planning multi-zone audio or 4K streaming over wired backhaul.
Estimate · Same-Day Availability
Not sure how much wall we'd need to open?
Talk to the team that handles every stage in-house, from the first walkthrough to Dolby Atmos calibration. We'll tell you upfront whether your project needs a fish tape or a saw, backed by a lifetime labour warranty on mounting and a written itemised estimate before any work begins.
How do you find wiring routes you can't see behind the drywall?
We treat every wall as a question mark until proven otherwise. A stud finder maps the framing, an endoscope camera confirms what's actually inside a cavity before we drill, and any electrical or duct run gets identified before cable goes anywhere near it. The framing decides the route, not the floor plan.
Older homes near the Wellington corridor complicate things further: plaster-and-lath walls hide smaller joist bays and trim nobody wants disturbed. We inspect the cavity with an endoscope first, then decide whether a small-bore fish-tape pull through an existing opening will get the cable where it needs to go, or whether one precise access cut is the faster, cheaper answer. Surface conduit only comes up if neither option works, and we say so before any tool touches the wall.
The most common job here is a finished basement in a house from the 1980s onward: drywalled, painted, trimmed, and not going anywhere near demolition. The route usually runs through the joist bays above a drop ceiling or through a closet that backs onto the theatre wall. A mechanical room next to the furnace is often the cleanest chase of all, since it already carries power and needs no finishing once we're done. Every opening we make gets mudded, sanded, and primer-matched before the final coat, so the wall looks untouched.
New construction in Bayview Wellington or the Hills of St. Andrew flips the job entirely: cable goes in before drywall closes, so there's no fishing and no patching at all. We coordinate that pre-wire directly with the general contractor. But most calls we get are for a room that's already built, which is why the retrofit skills matter more here than the pre-wire ones. Control4 home automation gets included on either path when a homeowner wants one-button scenes.
01 · Inspect First
We look before we drill.
An endoscope camera goes into the cavity before any tool touches drywall, so we know exactly what's behind the wall, framing, ductwork, and existing wiring, before we commit to a route.
02 · Use What's There
Closets and mechanical rooms double as chases.
A furnace room, a linen closet, a stud bay that's already open at the top: any of these can carry cable to the rack without a single visible run. We find the path that already exists before we consider cutting a new one.
03 · Cut Smart
One clean cut beats a long blind fish.
When a cavity won't cooperate, a small precise opening costs less than an hour of fishing tape through a dead end. We tell you which route we're taking and why, then patch and paint-match the opening so it disappears.
Recent Work · Aurora Highlands
A finished-basement build in Aurora Highlands.
A homeowner in this neighbourhood asked us to convert an existing finished basement into a dedicated cinema room: Dolby Atmos for film nights, plus distributed Sonos audio in the adjoining games room running from the same rack. The room already had drywall ceilings and 8-foot clearance, so the constraint was routing without tearing into the finished ceiling.

Cable routes ran through existing joist bays above the drywall ceiling, accessed at precise cut-outs around the speaker positions and patched flush before paint. No new bulkheads required.
OutcomeSingle-keypad switching between cinema mode and whole-floor background audio; calibration verified at the three-month service check.
The room sat at the back of the finished lower level with one exterior-facing wall, a coffered drop in the centre, and an existing in-floor speaker layout that the previous owner had installed and that needed a complete redo. We specified a 7.1.4 Dolby Atmos system using KEF in-ceiling drivers angled to the actual seating position, paired with a Marantz Cinema processor and multi-zone amplification feeding both the theatre and an adjoining games-room zone. The 100-inch motorised screen drops in front of a previously installed wall-mounted display, which now functions as a secondary daylight viewing surface.
The homeowner now drops the lights, drops the screen, and starts a movie from a single Control4 keypad by the entrance. Calibration was completed on the final visit; a follow-up service call confirmed the system was holding tune at the three-month mark. Distributed audio in the games room runs through our Sonos installation and on-site support workflow in Aurora, so future hardware changes plug straight into the existing zones.
Frequently Asked Questions
Still have questions about retrofitting a finished Aurora basement?
A media-room conversion with in-wall speakers and a rack closes in one to two working days. A full theatre with 5.1.4 or 7.1.4 Atmos, acoustic treatment, and projection runs two to four days across one or two visits.
Yes. We inspect the cavity with an endoscope camera, then pull cable through the existing joist bay or stud cavity with fish tape. When a route won't cooperate, one small access cut beats a long blind pull, patched flush before paint.
A media room with Dolby Atmos and a flat panel starts in the low five figures for labour and integration; a dedicated theatre with 4K projection, 5.1.4 or 7.1.4 surround, and Control4 costs more. Pre-wire rough-in is a half-day visit, no travel premium in Aurora.
Yes, on new construction in Bayview Wellington or anywhere else in town. We run HDMI, speaker cable, and Cat6 in-wall before drywall closes, coordinated directly with your contractor, so there's no fishing or patching needed later.
Yes, this is the most common job we take on. Drywall ceilings and wood-joist construction let us pull in-ceiling Atmos wiring through existing cavities. We cut precise openings for back-boxes, route cable back to the rack, and patch every opening before paint.
Atmos isn't required, but it's the current standard most new releases carry. It adds overhead height channels for three-dimensional sound instead of a flat plane. The minimum useful setup is 5.1.2; a dedicated theatre with an open ceiling gets the full effect from 7.1.4.
Depends on the room. In a dedicated basement with controlled lighting, a 4K laser projector and a 100- to 130-inch screen deliver a scale no flat panel matches at the price. A bright great room does better with an 85- to 98-inch display.
Yes. We're a Sonos Gold Dealer and Control4 Authorized Dealer. Sonos handles whole-home audio and pairs with Atmos-capable receivers over HDMI. Control4 runs full-room automation, lighting, shades, and the AV receiver, from one interface. Both get programmed in-house by our own certified technicians.
No, not in a standard drywall retrofit. Every run goes in-wall through the cavities we've mapped, and any access point gets mudded, sanded, and paint-matched before we leave. If a clean route genuinely isn't possible, we say so before you commit, not after.
Yes, across Aurora Highlands, Heights, the Wellington corridor, Bayview Wellington, Grove, Hills of St. Andrew, Estates, and Town Park, with no travel premium anywhere in the service area. We also serve neighbouring Newmarket, Richmond Hill, and the broader GTA.
