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

Short answer: The Same Guys Insulation is a Bowmanville attic insulation company based at 83 Henry Smith Ave, Bowmanville, ON. We remove old, wet, mouldy or rodent-damaged attic insulation, deal with the moisture behind it, and re-insulate to R-50 or better, usually toward about R-60. Most Bowmanville jobs are finished in one day, and as an approved Ontario Home Renovation Savings contractor we handle the contractor side of the Enbridge / Save on Energy attic rebate (up to $1,250 back on qualifying insulation).

Bowmanville is home base for us, not a service-area name on a list. The shop is on Henry Smith Ave in the south end, so a downtown Victorian, a mid-century bungalow near the old core or a newer house in Northglen or Brookhill is a short drive for the crew, the quote and any follow-up visit.

Bowmanville homes and their attics: what changes by era

Bowmanville started as a mill settlement on Bowmanville Creek. United Empire Loyalists arrived in 1794, Scottish merchant Charles Bowman bought land and promoted the village from 1824, and the community was incorporated as a village in 1853 and a town in 1858. The Municipality of Clarington’s Bowmanville Community Improvement Plan notes that much of the downtown core and the residential streets around it were built between 1850 and 1900 (Municipality of Clarington). The town joined the new Town of Newcastle in 1974, which was later renamed Clarington, and it remains Clarington’s largest urban centre.

That history gives Bowmanville three broad kinds of attic:

Downtown and the older streets around King, Liberty and Centre Streets (1850s to early 1900s). Clarington has designated several 1850s houses on Liberty Street North and late-19th-century homes on Centre Street as heritage properties (Clarington.net). Attics in houses this old are often cramped and have been re-insulated piecemeal over the decades, sometimes with layers of different materials. They take more care, and we look closely at access, venting and any older loose-fill before quoting.
Post-war and Highway 401-era homes (1950s to 1990s). Bowmanville stayed fairly rural until Highway 401 opened the area to commuters, and ranch bungalows and two-storeys filled in around the old core (Neighbourhood Guide). These are the attics we most often find packed down, patchy, or stained under bathroom fans. Many sit at or below R-35, which is the rebate cut-off.
Newer subdivisions (2000s to today). Northglen in the north and the Brookhill neighbourhood north of the Bowmanville West Town Centre are still building out (Brookhill Secondary Plan). These attics are usually in good shape and better insulated. They mostly need a depth check, and homes occupied for six months or less don’t qualify for the rebate.

Remove or top up? How we decide in a Bowmanville attic

Most homeowners don’t need to guess. We go up, measure the depth in several spots, and look at what’s underneath. The call usually comes down to these points:

Keep it and top up when the existing fibreglass or cellulose is dry, evenly spread, free of droppings and not sitting on mould. Adding new material over a sound layer to reach R-50 or more is the lower-cost route, and it still qualifies for the rebate if the attic starts at R-35 or less.
Remove it first when we find wet or crusted insulation, dark staining on the roof boards, a bathroom or kitchen fan venting into the attic, rodent nests and urine, smoke or fire damage, or old material compressed to a few inches. Burying those problems under fresh insulation hides them and stops us from sealing the air leaks that caused the damp.
Treat the cause, not just the symptom. Frost on nails, mould on sheathing and ice dams along the eaves usually point to warm, moist house air leaking into the attic. Removal gives us a bare floor to air-seal properly before the new insulation goes in.

More detail on the full process is on our attic insulation removal page and our guide to attic insulation removal and re-insulation in Durham Region.

A remove, mould and re-insulate job, step by step

Get a quote. Send us your address, attic details or a few photos and we’ll give you a quote. Removal, air sealing, baffles, any mould-related work and the new insulation are listed as separate lines, with the target R-value written down. For some homes, depending on age and construction, we do a quick site check before the job so there are no surprises.
Removal. Old insulation comes out with high-powered vacuums built for attic insulation, which keep dust and debris contained.
Moisture and mould. If we find mould on the sheathing or framing, we show you and coordinate the right treatment before anything new goes in. Fan ducts are rerouted outside and blocked soffits are opened.
Air sealing and baffles. With the floor bare, we seal the gaps that let moist air in and install baffles at the eaves.
Re-insulation. New insulation is blown in evenly to at least R-50, typically toward about R-60.
Clean-up and paperwork. We tidy up, walk you through what was done and complete the contractor-side rebate documents.

How Bowmanville homeowners claim the Enbridge / Home Renovation Savings attic rebate

The attic stream of the Ontario Home Renovation Savings program, run by Enbridge Gas and Save on Energy, needs no energy audit. It pays 50% of your after-tax attic insulation cost, up to a cap set by your starting insulation level (homerenovationsavings.ca):

R-12 or less before the upgrade: up to $1,250
Above R-12 up to R-25: up to $1,000
Above R-25 up to R-35: up to $800

In every case the finished attic must reach at least R-50 across 100% of the roof assembly. You must own the home, it must be a detached, semi, row or townhouse (not stacked) or a mobile home on a permanent foundation, and it must be heated primarily by Enbridge natural gas or be on the Ontario electricity grid. Homes that already received an attic rebate through an earlier Enbridge or IESO program are not eligible again.

The steps:

Check your eligibility and pre-register at homerenovationsavings.ca.
Call us at 647-453-7037, or send your address, attic details or a few photos, and we’ll give you a quote. For some homes, depending on age and construction, we do a quick site check before the job so there are no surprises.
Review the quote and sign the program terms. We confirm your rebate tier from the measured starting level.
We do the work: removal if needed, air sealing, then insulation to R-50 or higher.
We submit the contractor paperwork. You supply a copy of the invoice and your property tax bill.
The program pays the rebate once the documents are approved.

Two points matter on Bowmanville removal jobs. The program documents describe the rebate as covering the purchase and installation of insulation, so removal and mould work are priced separately. Enbridge Gas announced in October 2026 that the program has been extended to March 31, 2027. Confirm current dates on homerenovationsavings.ca or at 1-866-449-8510 before you book, because the official terms may still show the earlier date. Full details are on our Ontario attic insulation rebate guide.

Bowmanville attic insulation FAQ

The Same Guys Insulation is based in Bowmanville at 83 Henry Smith Ave and specializes in attic insulation removal and re-insulation, including Enbridge / Home Renovation Savings rebate jobs. The company has 95+ five-star Google reviews. Whoever you hire, ask for an itemized quote.

How much does attic insulation removal and re-insulation cost in Bowmanville?
It depends on attic size, how much has to come out, and whether there’s mould or rodent damage. Most of our attic projects range from about $1,500 to $4,500+, and full remove-and-re-insulate jobs sit toward the higher end. Quotes are free.

Is there an attic insulation rebate in Bowmanville in 2026?
Yes. Bowmanville homes can use the Ontario Home Renovation Savings attic rebate from Enbridge and Save on Energy: 50% of insulation cost up to $1,250, depending on your starting level, when a participating contractor brings the attic to R-50. Enbridge Gas announced in October 2026 that the program has been extended to March 31, 2027. Confirm current dates at homerenovationsavings.ca before booking, because the official terms may still show the earlier date.

Does the Enbridge rebate pay for removing old insulation?
Program documents describe the rebate as covering the purchase and installation of insulation. Removal and mould work aren’t listed, so we show them as separate lines on your quote.

My older Bowmanville house has an attic that’s hard to get into. Can you still do it?
Usually, yes. Older homes near downtown can have small hatches, low slopes or mixed layers of old insulation. Send photos of the hatch with your quote request; if access looks tight we may need a site check, and we will say so if a section cannot be done well.

I just bought a new build in Northglen or Brookhill. Do I need more attic insulation?
Often not yet. Newer homes are built to higher standards, and homes occupied for six months or less don’t qualify for the attic rebate. If you notice cold rooms or frost in the attic, we can check the depth and look for gaps.

How do I know if my attic has mould?
Common signs are dark or blotchy roof sheathing, a musty smell at the hatch, frost on nail tips in winter, and damp or clumped insulation. A bathroom fan venting into the attic is a frequent cause. We check for all of these when we see the attic — from your photos, or in person if a site check is needed.

Can you remove insulation contaminated by mice or raccoons?
Yes. Insulation with droppings, urine or nesting material should come out rather than be covered. We vacuum it out, and you should have the entry points sealed by wildlife control so the new insulation stays clean.

How long does an attic insulation removal take in Bowmanville?
Most jobs, including remove-and-re-insulate, are done in one day. Large attics, heavy contamination or mould treatment can add time, and we give you a realistic schedule when we quote.

Do I need to leave the house during attic insulation removal?
Usually not. The work happens in the attic, and our removal vacuums keep dust and debris contained. We protect the hallway or closet around the hatch and clean up when we’re done.

What R-value should a Bowmanville attic have?
The rebate program requires at least R-50 after the upgrade. We typically install toward about R-60 for a margin above that minimum.

Can I top up my attic insulation instead of removing it?
Yes, if the existing layer is dry, clean and evenly spread. A top-up to R-50+ is cheaper and still qualifies for the rebate when the attic starts at R-35 or less. We’ll tell you which option fits after measuring.

Are you on the official Home Renovation Savings contractor list?
Yes. The Same Guys Insulation is an approved attic contractor for the program. You can confirm it on the participating contractor list you receive when you pre-register at homerenovationsavings.ca.
