Exterior Walls and Ceilings
Batts are cut to fill each cavity completely and split around wiring and pipes rather than stuffed behind them.
Insulation and drywall in Kingston, ON
Insulation and Drywall Installation in Kingston, Ontario
Kingston Drywall Pros installs insulation, vapour barrier and drywall as one package for renovations, additions and basements across Kingston. Homeowners and builders use us so a single crew owns the wall from bare studs to paint-ready board.
When insulation and drywall are split between two trades, the vapour barrier gets torn while boarding, a batt gets compressed behind an outlet, and each trade blames the other. One crew closes that gap.
We know what Kingston building inspectors check at the insulation and vapour barrier stage, and we never board over insulation that has not been signed off.

Service overview
Our Insulation and Drywall Services
Insulation and drywall is a combined service where we insulate the wall or ceiling cavities, install and seal the vapour barrier, then hang and finish the drywall. It turns open framing into finished, energy-code-compliant walls with one booking.
It suits renovators and homeowners finishing basements, building additions or converting garages, and builders who want fewer trades on site. The package includes:
- Fibreglass batt or mineral wool in exterior walls, ceilings and partitions
- Rigid foam against basement foundation walls
- Polyethylene vapour barrier with sealed laps, boxes and penetrations
- Scheduling around the municipal insulation and vapour barrier inspection
- Drywall hung, taped and finished to the level on your quote
Insulation options
Types of Insulation We Install Behind Drywall
The right insulation depends on whether the wall needs thermal, fire or sound performance and whether it is above or below grade. These are the options we install and when each fits.
| Insulation | What it is | Best for |
|---|---|---|
| Fibreglass batt | Friction-fit glass fibre batts, around R-3.5 per inch | Exterior walls and attic-side ceilings on a budget |
| Mineral wool batt | Stone wool batts such as Rockwool, denser and non-combustible | Fire separations, shared walls and sound control |
| Rigid foam board | XPS, EPS or foil-faced polyiso panels | Against basement concrete to keep framing warm and dry |
| Closed-cell spray foam | Foam that air seals and insulates in one layer | Rim joists and tight spots; installed by a spray foam specialist |

Where we insulate
Insulation Work We Install Ahead of Drywall
Most insulate-and-board jobs cover some mix of these six areas.
Fire and Sound Separations
Mineral wool goes in shared walls, furnace rooms and garage separations, where its fire and sound performance matter.
Interior Partitions
Insulating interior walls for privacy is cheap while walls are open and costly later. It is a common request for bedrooms and bathrooms.
Basement Foundation Walls
Rigid foam against the concrete, then a stud wall with batts, keeps condensation off the framing on Kingston's damp limestone and clay sites.
Attic Hatches and Bulkheads
Hatches, knee walls and bulkheads are where heat actually escapes. We insulate and seal them instead of leaving cold cavities.
Vapour Barrier Detailing
Overlapped and sealed poly, acoustic sealant at plates and sealed electrical boxes are exactly what an inspector looks for.
How it works
Where Insulation Sits in the Build Sequence
The order is fixed by the Ontario Building Code inspection process, and insulation is never boarded over before it is inspected.
- 1
Rough-In
Electrical, plumbing and HVAC rough-ins are completed and inspected where required.
- 2
Insulation
Batts or mineral wool fill every cavity, with rigid foam on foundation walls.
- 3
Vapour Barrier
Poly goes on the warm side, with laps, boxes and penetrations sealed.
- 4
Inspection
The municipal building inspector checks insulation and vapour barrier before close-in.
- 5
Board and Finish
Drywall is hung, taped and finished once the inspection passes.
Code and climate
What R-Value Do Walls Need in Kingston?
New above-grade walls in Kingston commonly need about R-22, basement walls about R-20 and attic ceilings about R-60. Kingston falls in Zone 1 of the Ontario Building Code energy requirements, with fewer than 5,000 heating degree days.
Supplementary Standard SB-12 sets these minimums, and your designer's compliance package lists the exact values. When comparing quotes, check that each one states the R-value and product for every area.

Failure modes
Common Insulation Mistakes Behind Drywall
Most insulation problems are hidden once the drywall goes up, which is why they matter so much. These are the ones we see when opening other people's walls:
- Compressed batts stuffed behind wiring, which lose much of their R-value.
- Torn or unsealed poly at outlets and plates, letting warm moist air into the wall.
- Poly against basement concrete with nothing between, trapping condensation on the framing.
- Cold bulkheads boxed in with no insulation, where pipes can freeze.
- Gaps at rim joists left open, one of the biggest air leaks in a basement.
Bulkheads
Bulkheads, Soffits and Boxing In Services
A bulkhead is a framed box that hides ductwork, beams or plumbing below the ceiling line. Done well, bulkheads look intentional and line up across the room.
Bulkheads along exterior walls or into unheated spaces need insulation and air sealing too, or they become cold cavities where condensation and frozen pipes start.
Pricing
How Much Does Insulation and Drywall Cost?
Insulation and drywall are priced per square foot, separately or as a package, and bundling usually costs less than hiring two trades.
| Approach | What you pay for | Where the saving comes from |
|---|---|---|
| Separate trades | Two mobilisations, two schedules, two warranties | None |
| Insulate and board package | One crew, one schedule, one point of responsibility | Shared set-up and no idle days between trades |
FAQ
Insulation and Drywall FAQs
Straight answers to the questions we hear on site visits every week.
Do I need an inspection before you board over insulation?
If your project has a building permit, yes. The municipal inspector checks insulation and vapour barrier before drywall goes on, and we schedule around that inspection.
Batt or spray foam for a Kingston basement?
Both can meet code. Rigid foam against the concrete with batts in the stud wall is cost-effective and handles moisture well; closed-cell spray foam air seals better but costs more and needs a specialist.
Can you insulate an interior wall for sound only?
Yes. Mineral wool in interior partitions noticeably reduces sound between rooms; for bigger gains see drywall soundproofing.
Do you remove old or wet insulation before reboarding?
Yes. Wet, compressed or mouldy insulation is removed and bagged before new insulation goes in.
