Millbrook is the village at the centre of the Township of Cavan Monaghan, in Peterborough County. The downtown and nearby streets hold a large share of the township’s heritage houses, with farms and later rural homes on the concessions around it. Bethany, just west in the City of Kawartha Lakes, is on the same north-bound route and is included on this page. We recommend removal only when the existing layer should not stay.
Attic insulation removal and re-insulation in Millbrook
- Complete removal when the existing insulation is aged, wet, mouldy, contaminated by mice, squirrels or raccoons, or packed too flat to leave in place
- A moisture and mould review of the roof sheathing, bath-fan ducts and soffit vents once the attic floor is visible
- Air sealing at top plates, plumbing stacks, wiring holes and fixtures after the old material is gone
- Soffit baffles so the new layer does not block intake air at the eaves
- Blown-in insulation to at least R-50, the rebate minimum, and typically toward about R-60
- A top-up only when the current layer is dry, even and still doing its job
Basement insulation is also available.
Millbrook houses, and the attics that come with them
Millbrook grew around milling on the brook that gave the village its name. The township traces the first sawmill to John Deyell in 1816, on the site where Needler’s Mill stands today. A fire in 1875 destroyed much of the business district along King and Tupper Streets, and the rebuilt core, together with earlier houses that survived, is a large part of why the township records 45 historically designated buildings (Township of Cavan Monaghan). That history shows up in the attic in a few consistent ways:
- Heritage and older village houses near King, Tupper and the streets around Needler’s Lane. Attics in houses this old are often low, irregular, or reached through a tight hatch, with insulation added in layers over many decades. Photos of the hatch are usually enough to start a quote; we only come out first if access or the age of the house makes a site check necessary.
- Farmhouses and mid-century homes on the concessions around Millbrook, and in Bethany. These are more often a depth and settling problem than an access problem. Many sit below today’s R-50 rebate minimum, and a bathroom fan or blocked soffits can leave the insulation stained or packed down.
- Newer rural houses along the 115 corridor. These attics usually just need a depth check. If the attic is already above R-35, it no longer qualifies for the rebate, and homes occupied for six months or less are not eligible.
When a Millbrook attic should be emptied first
The choice is based on what we can see in your photos, or on a site check if the house actually needs one:
- Add more depth and leave the old layer if it is dry, level and clean. That is usually the less expensive way to get to R-50 or better, and the rebate still applies when the starting level is R-35 or lower.
- Empty the attic first if the material is damp, crusted or stained, if a bath fan is blowing into the attic, if we see nests, or if what is left is only a few inches thick. A new blanket over that leaves the leaks and the damage in place.
- Seal first, then fill. Ice at the eaves or frost on the nails usually means house air is escaping into the attic. Taking the old layer out gives us a clear floor to seal.
The same method, described in more detail, is on our Durham Region attic removal page.
Quote first, then the drive to Millbrook
The shop is about 45 km south, a 35- to 40-minute run up Highway 115. Bethany is about 40 km. We write the price from the address, the age of the house and hatch photos. We come north beforehand only when the house itself requires a look:
- A written price from what you send. Each of removal, sealing, baffles, any mould-related work and the new insulation has its own line, and the finished R-value is on the quote.
- A look in person only if it is needed. Heritage houses, a tight hatch, or photos that leave too much out of view may need one. We do not drive up just to put a number on paper.
- Take-out, when the old layer cannot stay. We vacuum it out. If you are claiming the attic rebate, the starting R-value has to be written down on site before any insulation is moved. That is a program rule for the job, not a step you must take to get a quote.
- Moisture work, then sealing. If we find mould on the boards or framing, we show you and arrange treatment before anything new goes in. Fans are ducted outside, soffits are opened, floor gaps are sealed, and baffles go in at the eaves.
- The new layer and a clean finish. We blow in an even fill to at least R-50, typically toward about R-60, clean up, review the work with you, and handle the contractor side of the rebate forms.
Most Millbrook and Bethany remove-and-refill jobs are done in a day; a large attic or mould issue is noted on the quote.
The Home Renovation Savings attic rebate in Millbrook
Cavan Monaghan and Bethany homeowners can use the no-assessment attic stream run by Enbridge Gas and Save on Energy. The payment is 50% of the after-tax insulation cost, with a ceiling that depends on the starting level recorded on site before work begins:
- From R-12 or less, the ceiling is $1,250
- From R-13 through R-25, $1,000
- From R-26 through R-35, $800
The finished attic has to land at R-50 or higher. A cathedral ceiling or a flat roof is capped at $750 or $650. Only the insulation itself is covered; removal and mould work stay on their own lines. Ownership is required. Heat must be an Enbridge gas furnace or boiler, or electricity, oil, propane or wood in a house connected to the Ontario electricity grid — a path that matters on rural lots around Millbrook and Bethany that have no gas service.
The Same Guys Insulation is a participating contractor: we check eligibility, do the work to the program standard, and file our paperwork. The program has been extended to March 31, 2027, as announced by Enbridge Gas in October 2026; confirm current dates at homerenovationsavings.ca.

FAQ — attic insulation in Millbrook, Ontario
Do the older designated houses in downtown Millbrook usually need the insulation taken out?
More often than the newer concession houses, yes. Low clearances, mixed old layers and venting that was never planned for a modern blow-in are common there. If what is in place is dry and even, adding depth can still be enough.
How far is Millbrook from your Bowmanville shop, and does that change how you quote?
About 45 km, or 35 to 40 minutes via Highway 115. The price is written from the address and hatch photos, so we are not driving up only to estimate. Call 647-453-7037 and send what you can see at the hatch.
Can I claim the Enbridge attic rebate on a Millbrook or Bethany home that isn’t on natural gas?
Often yes, if the rest of the rules are met. Enbridge gas heat qualifies, and so does electricity, oil, propane or wood in a house on the Ontario electricity grid. The attic has to reach R-50, and the payment is 50% of after-tax insulation cost, with ceilings of $1,250, $1,000 or $800. The program has been extended to March 31, 2027, as announced by Enbridge Gas in October 2026; confirm current dates at homerenovationsavings.ca.
Does the rebate pay for removing old insulation in Millbrook?
It does not. Only the purchase and installation of insulation are covered. Take-out and mould work are priced on their own lines.
Do you also serve Bethany and the rest of Cavan Monaghan?
Yes. Bethany is about 40 km from the shop, and the rest of the township is on the same north route. See also Peterborough, Orono and Lakefield.
How much does attic insulation removal and re-insulation cost in Millbrook?
Size, how much has to come out, and any mould or rodent damage set the price. Work usually falls between about $1,500 and $4,500 or more, with a full take-out at the upper end. The quote is free.
My Millbrook attic hatch is small. Can you still do the work?
In many houses, yes. Village and heritage attics often have a tight hatch or a low slope. Include hatch photos with the quote request. If access looks tight we may need a site check, and we will tell you if a section cannot be done properly.

Call 647-453-7037 or email info@thesameguysinsulation.com. If you send the address and a few photos looking up from the hatch, we’ll write the quote from that. A site check happens first only when the house is old enough, or built in such a way, that photos are not enough.
