Short answer: The Same Guys Insulation removes old, wet, mouldy or rodent-damaged attic insulation and re-insulates homes in Trenton and the rest of Quinte West, Ontario. The shop is at 83 Henry Smith Ave in Bowmanville, about 105 km west on Highway 401 — typically a little over an hour, often around 70 to 80 minutes depending on traffic. Most remove-and-re-insulate jobs finish in one day. Qualifying upgrades can receive 50% of the after-tax insulation cost back, up to $1,250, through the Ontario Home Renovation Savings / Enbridge attic rebate. Call 647-453-7037.
Trenton is the main urban centre of the City of Quinte West, at the mouth of the Trent River on the Bay of Quinte. The city also includes Frankford and the former townships of Sidney and Murray. Housing ranges from older streets near downtown and the river, to post-war neighbourhoods, later subdivisions, and rural homes farther out. We quote from the details of your house, not a city-wide average.
What a Trenton attic job includes
- Removal with attic vacuums when the existing material is wet, mouldy, packed down, or contaminated by mice, squirrels or raccoons
- A review of the roof deck and of bathroom and kitchen fan ducts once the sheathing is visible
- Air sealing at plumbing stacks, wiring penetrations, fixtures and the hatch after the floor is bare
- Soffit baffles so intake air at the eaves is not blocked by the new layer
- An even blown-in fill to at least R-50, the rebate minimum, and usually toward about R-60
- A top-up only when the current insulation is dry, clean and still serviceable
Basement insulation is also available.
Trenton and Quinte West housing, from the river streets to the concessions
The City of Quinte West was created in 1998 by the amalgamation of the City of Trenton, the Village of Frankford, Sidney Township and Murray Township. The city sits between Toronto and Kingston, at the southern entrance to the Trent-Severn Waterway, and is home to 8 Wing / CFB Trenton, Canada’s largest air force base (City of Quinte West). That mix of an older river town, later residential streets, and rural township land is what we see in the attic:
- Older houses near downtown Trenton and along the Trent River. Attics in this stock are often tight, with small hatches and insulation added over many years. They take more care on access and venting, and we will say so if a section cannot be done well.
- Post-war bungalows and later subdivisions across Trenton, and houses in Frankford. Settling and thin spots are more typical than an access problem. A bath fan, blocked soffits or a cold upstairs room are common reasons these attics get a closer look, and many start below the R-50 rebate minimum.
- Rural homes in the former Sidney and Murray township areas, and newer houses on the edges of Trenton. These attics mainly need a depth check. If the starting level is already above R-35, the rebate no longer applies, and a home occupied for six months or less is not eligible.
Deciding whether a Trenton attic needs to be emptied
Photos from the hatch, or a site check if the house actually needs one, usually make the path obvious:
- Keep the current insulation and add to it when it is dry, evenly laid and clean. That is the less costly way to reach R-50 or better, and it remains eligible when the attic starts at R-35 or lower.
- Take it out when the layer is wet or crusted, the roof boards are stained, a fan is exhausting into the attic, there are nests or urine stains, or only a thin pad is left. A new blow-in over that leaves the leaks alone.
- Seal the floor, then insulate. Frost on the nails, ice along the eaves or a musty hatch means house air is reaching the attic. Clearing the floor is what lets us close those gaps.
The same logic is set out on our Durham Region removal and re-insulation page.
Planning a Trenton or Quinte West job from Bowmanville
Trenton is about 105 km east on the 401, typically a little over an hour and often 70 to 80 minutes depending on traffic. We therefore write the quote from details and photos, and we make the trip when a site check is genuinely needed or when the work is booked, often alongside Brighton or Colborne:
- A written quote from the address, the age of the house and hatch photos. Removal, sealing, baffles, mould-related work and the new insulation each have a line, and the finished R-value is stated.
- A site check only if the house requires one. An older downtown attic, a tight hatch, or photos that leave too much unseen may need it. We do not drive to Quinte West just to put a price on paper.
- Vacuum-out, when the old layer cannot stay. If the rebate is being used, the starting R-value is recorded on site before any insulation is moved. That is required for the program, not for the estimate.
- Moisture work, then air sealing. Mould on the sheathing or framing is shown to you and treated before anything new is installed. Fans are ducted outdoors, soffits are opened, floor leaks are sealed, and baffles are set at the eaves.
- The new fill and a clean finish. An even blow-in to at least R-50, typically toward about R-60, then clean-up, a review with you, and the contractor rebate forms.
Most Trenton remove-and-refill jobs, including a full take-out, are finished in one day. A very large attic or a mould issue can run longer, and we note that on the quote.
The attic rebate in Trenton and the rest of Quinte West
Quinte West residents can use the Ontario Home Renovation Savings attic program from Enbridge Gas and Save on Energy without an energy assessment. It returns 50% of the after-tax insulation cost, up to a cap set by the starting level recorded on site:
- Starting at R-12 or less: up to $1,250
- Starting at R-13 to R-25: up to $1,000
- Starting at R-26 to R-35: up to $800
The finished attic must be at least R-50. Cathedral ceilings and flat roofs are capped at $750 or $650. The program pays for insulation, not for take-out, which is why those items are priced separately. You must own the home. Heat must be an Enbridge gas furnace or boiler, or electricity, oil, propane or wood in a house connected to the Ontario electricity grid. Rural properties in the former Sidney and Murray areas that are off gas can still qualify on that second path.
The Same Guys Insulation is a participating contractor. We confirm whether the house qualifies, complete 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 before you book. The longer explanation is on our Ontario attic insulation rebate guide.

FAQ — attic insulation in Trenton and Quinte West, Ontario
Do you serve all of Quinte West, or only downtown Trenton?

How far is Trenton from your Bowmanville shop, and does that change scheduling?
About 105 km east on the 401, typically a little over an hour and often 70 to 80 minutes depending on traffic. We price the job from details and photos, and we often group it with other east-end work. Call 647-453-7037 with the address and hatch photos.
Can I claim the Enbridge attic rebate on a Trenton or Quinte West home?
Yes, when the house and the upgrade qualify. You must own it, and it must be heated by Enbridge gas or by electricity, oil, propane or wood on the Ontario electricity grid. A participating contractor has to bring the attic to at least R-50. The payment is 50% of after-tax insulation cost, up to $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 Trenton?
No. It covers insulation purchase and installation. Take-out and mould-related work are priced separately.
Are older houses near the river or downtown harder to insulate?
They can be, usually because of a small hatch, a low slope, or mixed old layers. Send hatch photos with the request. If access looks tight we may need a site check, and we will tell you if a section cannot be done properly.
How much does attic insulation removal and re-insulation cost in Trenton?
The number depends on attic size, how much has to come out, and whether mould or rodents are involved. Most projects fall between about $1,500 and $4,500 or more, with a full take-out at the higher end. Quotes are free.
If I live in Frankford, is the process the same?
Yes. Frankford is part of Quinte West and is quoted the same way: details or photos first, with a site check only if the age or type of home makes one necessary.
