Question 1

Why does my Dieppe home's attic insulation seem to compress and lose R-value every spring after a harsh New Brunswick winter?

Accepted Answer

Your attic insulation is likely experiencing moisture-related compression from ice damming, inadequate air sealing, or ventilation problems that are common in Dieppe's Maritime climate. This seasonal compression indicates that your insulation is getting wet during winter freeze-thaw cycles, then compacting as it dries in spring.

Moisture is the primary culprit behind insulation compression in New Brunswick homes. During our long winters with temperatures regularly hitting -20 to -30°C, warm, mo

Question 2

How long does moisture damage repair and re-insulation of a Rothesay basement typically take?

Accepted Answer

Moisture damage repair and re-insulation of a Rothesay basement typically takes 2-6 weeks from start to finish, depending on the extent of damage, drying time required, and scope of the insulation upgrade.

The timeline breaks down into several critical phases that cannot be rushed. Moisture assessment and source elimination takes 3-7 days and involves identifying all water entry points — foundation cracks, poor grading, failed window wells, or plumbing leaks. In Rothesay's clay-heavy soils near

Question 3

What are the signs that spray foam insulation has shrunk or pulled away from framing members in a New Brunswick home, and how does this compare to rigid foam delamination?

Accepted Answer

Spray foam shrinkage and rigid foam delamination are both serious insulation failures that create thermal bridges, air leakage paths, and moisture problems — but they present different warning signs and occur for different reasons in New Brunswick's challenging climate.

Spray Foam Shrinkage Warning Signs

Visual indicators are the most obvious signs of spray foam problems. Look for gaps between the foam and framing members — you'll see daylight, feel air movement, or notice the foam has physic

Question 4

Can missing insulation in one wall cause pipes to freeze in a Sussex NB home? | Insulation IQ?

Accepted Answer

Yes — a single wall cavity with missing or inadequate insulation is absolutely capable of causing pipes to freeze in a Sussex home, and it happens more often than homeowners expect. The mechanics of how this occurs are worth understanding, because the fix is straightforward once you know what you are dealing with.

Water supply pipes that run through exterior walls are in a thermally hostile location by design, and they depend entirely on the insulation in that wall cavity to keep them above fre

Question 5

How do I check for insulation voids using a thermal camera in New Brunswick? | Insulation IQ?

Accepted Answer

Thermal imaging is one of the most powerful diagnostic tools available for assessing insulation performance, and New Brunswick's climate actually makes it an especially effective technique. The large temperature difference between indoors and outdoors during a NB winter creates strong thermal contrast that makes insulation voids easy to identify — provided the inspection is done under the right conditions and interpreted correctly.

How thermal imaging works for insulation inspection is straight

Question 6

Why is my energy bill so high even after insulating in a Bathurst NB home? | Insulation IQ?

Accepted Answer

Adding insulation is one of the most impactful upgrades you can make to a home in Bathurst, but it is surprisingly common to complete an insulation project and still see little improvement on your NB Power bill. The reason is almost always that insulation alone cannot solve an air leakage problem — and in an older Bathurst home, those two issues almost always coexist.

Insulation slows the movement of heat through solid materials by a process called conduction. However, a large portion of heat l

Question 7

How do I fix drafts around old windows in an insulated New Brunswick home? | Insulation IQ?

Accepted Answer

Drafts around windows are one of the most common and most frustrating comfort complaints in New Brunswick homes, particularly in older houses in cities like Fredericton, Saint John, and Miramichi where double-hung wood-framed windows from the 1960s through 1990s are still common. The good news is that most window drafts can be fixed without replacing the windows, and when addressed properly, the improvement in comfort and energy savings can be significant.

Understanding the source of the draft

Question 8

What causes insulation to sag or fall out of basement walls in NB? | Insulation IQ?

Accepted Answer

Insulation falling or sagging out of basement walls is a very common problem in New Brunswick homes, and it is almost always a sign that the original installation method was inadequate for the conditions a basement presents. Understanding why it happens is the first step to fixing it properly and ensuring the replacement holds up for the long term.

The most frequent cause is fibreglass batt insulation installed between basement wall studs without an adequate retainer. Batts rely on friction — t

Question 9

How do I deal with insulation that has been contaminated by raccoons in NB? | Insulation IQ?

Accepted Answer

Raccoon contamination is among the most serious insulation problems a New Brunswick homeowner can face, and it demands a careful, methodical approach. Raccoons are intelligent, persistent, and common throughout the province — from suburban Moncton and Fredericton to rural properties near Miramichi and Woodstock. When they establish themselves in an attic, the damage they leave behind creates both a significant health hazard and a complete insulation failure that cannot be remediated by simply ad

Question 10

Can I repair insulation myself or should I hire a contractor in Miramichi NB? | Insulation IQ?

Accepted Answer

It's a fair question, and the honest answer depends heavily on what kind of repair you're dealing with. Some insulation repairs in a Miramichi home are genuinely accessible to a confident DIYer; others are categorically not — either because of health hazards, technical complexity, or the risk of making things significantly worse. Knowing which category your repair falls into before you climb into the attic can save you considerable money and protect your health.

What homeowners can reasonably d

Question 11

What causes frost buildup in attics during New Brunswick winters? | Insulation IQ?

Accepted Answer

Attic frost is one of the more alarming discoveries a New Brunswick homeowner can make — and it's more common here than in most of Canada, for good reason. Our climate routinely delivers the combination of conditions that makes frost formation almost inevitable in poorly performing attic assemblies: cold outdoor temperatures, high indoor humidity, and rapidly fluctuating weather patterns that bring freeze-thaw cycles throughout the winter. Understanding the mechanics of how frost forms is essent

Question 12

Why are some rooms in my New Brunswick home colder than others? | Insulation IQ?

Accepted Answer

Uneven room temperatures are one of the most common comfort complaints in New Brunswick homes, and insulation deficiencies are among the leading causes — though the full answer is almost always multi-layered. Understanding the specific reasons rooms feel cold while others stay comfortable helps you target the right fix and avoid spending money on the wrong solution.

Thermal bypasses and air leakage are frequently the root cause behind rooms that feel cold even when the thermostat is set high. A

Question 13

How do I tell if animals have damaged my attic insulation in NB? | Insulation IQ?

Accepted Answer

Animal intrusion is one of the most destructive and frequently overlooked causes of insulation failure in New Brunswick homes. Squirrels, raccoons, mice, bats, and starlings all find attic spaces attractive year-round — particularly during our harsh winters — and the damage they leave behind is far more serious than most homeowners realise. The good news is that with careful inspection, the signs are usually unmistakable.

The most obvious indicator is visible nesting material. Animals tear apar

Question 14

Can old insulation contain asbestos in a New Brunswick home built before 1990? | Insulation IQ?

Accepted Answer

Yes — and this is a question that every New Brunswick homeowner with an older property should take seriously. Asbestos-containing insulation materials were widely used in Canadian construction from the 1930s through the late 1980s, and New Brunswick is no exception. Homes built or renovated before 1990 in Fredericton, Saint John, Moncton, Bathurst, and communities throughout the province may contain one or more forms of asbestos insulation, depending on the construction period and original build

Question 15

What should I do about mould on insulation in my Moncton attic? | Insulation IQ?

Accepted Answer

Finding mould in your Moncton attic is alarming, but it's also one of the most common attic problems in New Brunswick — and it's almost always a symptom of a fixable underlying cause. The key is to address the mould and its root cause together, because treating the visible growth without eliminating what's feeding it will result in a return visit within one to two seasons.

Mould grows in attics when warm, humid air meets cold surfaces. In Moncton's climate, the mechanism is straightforward: hum

Question 16

Why is my New Brunswick home cold even with the heat turned up? | Insulation IQ?

Accepted Answer

If your New Brunswick home feels cold despite the thermostat being cranked up, the problem almost certainly isn't your furnace — it's your building envelope. New Brunswick's Climate Zone 6 winters are harsh, with Fredericton regularly dipping below -25°C and Saint John and Moncton experiencing sustained cold snaps that expose every weakness in a home's thermal defence. Heat doesn't just disappear; it escapes through specific, identifiable pathways, and understanding those pathways is the first s

Question 17

What causes ice dams on New Brunswick homes and how does insulation help? | Insulation IQ?

Accepted Answer

Ice dams are one of the most visible and destructive consequences of poor attic insulation, and they're a common sight across New Brunswick during and after the heavy winter storms that regularly hit Moncton, Fredericton, Saint John, and the Miramichi. Understanding what creates them — and why insulation is the real solution — can save homeowners thousands of dollars in roof and interior damage.

An ice dam forms when heat escaping from the living space below warms the underside of a snow-covere

Question 18

How do I fix wet or water-damaged insulation in my Fredericton basement? | Insulation IQ?

Accepted Answer

Wet insulation in a Fredericton basement is not a problem you can simply dry out and leave in place. Unlike most building materials, fibreglass batt insulation loses the vast majority of its thermal performance when saturated, and it does not recover fully even after drying. More importantly, moisture trapped within wall or floor cavities creates ideal conditions for mould growth, wood rot, and long-term structural deterioration — all of which are significantly more expensive to remediate than t

Question 19

What are the signs of poor insulation in a Saint John home? | Insulation IQ?

Accepted Answer

Saint John sits in one of the most thermally demanding environments in eastern Canada. The city's position on the Bay of Fundy exposes it to sharp wind chill, persistent coastal dampness, and significant temperature swings across the heating season -- conditions that expose insulation deficiencies faster and more painfully than almost anywhere else in the province. Recognizing the signs of poor insulation in a Saint John home early can save you thousands in heating costs and prevent the kind of
