Attic Insulation Removal & Re-Insulation in Whitby, ON | The Same Guys

Short answer: The Same Guys Insulation removes and replaces attic insulation for Whitby, Ontario homeowners, from downtown Whitby and Port Whitby to Brooklin. Our crew comes west along Highway 401 from our Bowmanville shop at 83 Henry Smith Ave. We take out insulation that’s wet, mouldy, contaminated or packed down, seal the air leaks underneath, and re-insulate to R-50 or better. Most jobs take one day, and eligible Whitby homes can get up to $1,250 back on the insulation through the Ontario Home Renovation Savings / Enbridge attic rebate. Call 647-453-7037.

Whitby is a regular part of our Durham Region schedule. Whitby jobs go on the same weekly route as Oshawa and Courtice, so you’re not waiting on a one-off trip. We usually quote first from details or photos.

Whitby’s housing eras: from Port Whitby to Brooklin

Whitby was incorporated as a town in 1855. In the 1870s the Port Whitby and Port Perry Railway was built north from the harbour at Port Whitby (Wikipedia). Brooklin, the village in north Whitby, grew much later. The Meadowcrest subdivision west of Baldwin Street added ranch-style homes in the late 1950s. Large-scale building didn’t resume until the mid-1990s, with the Village of Brooklin subdivision between Queen Street and Thickson Road, then growth toward Ashburn Road around 2000 and Olde Winchester from 2001. Downtown Brooklin became a Heritage Conservation District in 2008 (Brooklin history).

What that means for Whitby attics:

Downtown Whitby, Port Whitby and heritage Brooklin: 19th- and early 20th-century homes with smaller attics, older loose-fill and decades of patchwork. These need careful checks for access, venting and anything that shouldn’t be disturbed.
1950s–1980s homes, including Meadowcrest-era ranches: attics that are often well below R-35 and settled thin. This is where we do the most removals, usually because of rodent damage, old fan leaks or uneven coverage.
1990s–2000s two-storeys across south Whitby and Brooklin: usually better insulated but now 20 to 30 years old. Common problems are wind-washed eaves, missed corners and a few inches of settling. Many can get a top-up rather than removal.

Remove or top up a Whitby attic?

We base the recommendation on what we find in your attic. Here’s how we decide:

Dry, clean and even? A top-up to R-50 or more is the sensible choice. It costs less and still qualifies for the rebate if the attic currently measures R-35 or less.
Wet, mouldy, soiled by animals or crushed flat? Take it out. Covering damaged material hides the problem, keeps the moisture in and blocks the air sealing that keeps a new layer dry.
Above R-35 already? The attic no longer qualifies for the rebate. Unless there’s a specific problem, more insulation may not be worth the cost.

Questions to ask any Whitby attic insulation contractor

Did you measure my current R-value in more than one spot?
Why should my old insulation stay, or why should it go? Can you show me?
Is the quote itemized, with removal, sealing, baffles and insulation listed separately and a finished R-value stated?
Are you a participating Home Renovation Savings contractor, and will you record the starting insulation level before any old insulation comes out?
Can you confirm your insurance and WSIB coverage?

Enbridge and the IESO say they don’t solicit by phone or door to door. Treat anyone claiming to be “from the rebate program” with caution.

The Home Renovation Savings / Enbridge attic rebate in Whitby

Whitby homes can use the attic-only stream of Ontario’s Home Renovation Savings program, run by Enbridge Gas and Save on Energy, with no energy assessment required. It reimburses 50% of the after-tax insulation cost. The maximum depends on the attic’s starting insulation level: $1,250 at R-12 or below, $1,000 above R-12 to R-25, and $800 above R-25 to R-35. Every case requires a finished level of at least R-50 (homerenovationsavings.ca). Owners of detached, semi, row and townhomes (not stacked) qualify if they heat mainly with Enbridge gas or are on the Ontario grid. Homes rebated for attic insulation before are excluded, and so are new builds occupied six months or less.

On removal jobs we record your starting tier before anything is taken out. Program documents describe the rebate as covering insulation purchase and installation, so removal and mould work are separate line items. Enbridge Gas announced in October 2026 that the program has been extended to March 31, 2027. Confirm current dates at homerenovationsavings.ca before you book, because the official terms may still show the earlier date. See our Ontario attic insulation rebate guide for the full steps.

Whitby attic insulation FAQ

Who does attic insulation removal in Whitby, Ontario?
The Same Guys Insulation, a Durham Region contractor based in Bowmanville, removes and replaces attic insulation in Whitby and Brooklin, including Enbridge / Home Renovation Savings rebate jobs. Call 647-453-7037.

Do you work in Brooklin as well as south Whitby?
Yes. Brooklin, downtown Whitby, Port Whitby and the subdivisions in between are all part of our service area.

My 1990s Whitby home has cold upstairs bedrooms. Is it the attic?
It often is. Settled insulation, gaps at the eaves and air leaks around pot lights are common in homes that age. We look at the depth and check for wind-washing before recommending a top-up or removal — usually from your photos, or in person if the house needs a site check.

Can I get the Enbridge rebate if I live in a Whitby townhouse?
Row and townhomes are eligible, but stacked townhouses are not. You also need to own the unit and have attic access that covers your whole roof area.

Does the attic rebate cover removing old insulation in Whitby?
Program documents describe the rebate as covering insulation purchase and installation. Removal isn’t listed, so we price it separately on the quote.

How much does attic insulation cost in Whitby?
It depends on attic size, the existing level and whether removal or mould work is needed. We give free, itemized quotes after measuring, so you know the cost before anything starts.

What R-value should my Whitby attic be?
At least R-50 to meet the rebate program’s minimum. We typically aim for about R-60.

Is there mould in my attic if I see black spots on the roof boards?
Possibly. Dark staining on the sheathing is often mould from moist house air or a leak. We check when we see the attic — from your photos, or in person if a site check is needed — and coordinate treatment before re-insulating if needed.

Can attic insulation work be done in a heritage-district home in Brooklin?
Attic insulation is interior work. Heritage district rules mainly concern exterior changes, but check with the Town of Whitby if you’re planning new roof vents or other exterior changes.

How long does a Whitby attic insulation job take?
Most jobs, including removal and re-insulation, are done in one day. Larger attics or heavy contamination can take longer.

Should I re-insulate my Whitby attic before or after a new roof?
If roof boards are being replaced or there’s an active leak, fix the roof first so the new insulation stays dry. If the roof is sound, the attic can be done any time. Tell us about any roofing plans when you book and we’ll schedule around them.
