Common attic problems

Most attic issues trace back to the same hidden causes

If any of these sound familiar, your attic is likely under-performing — and it's usually fixable in a single visit.

Uneven temperatures

Some rooms are always colder or hotter because heat escapes through an under-performing attic.

Mold or damage signs

Staining, mold, or damp insulation point to moisture problems and possible structural concerns.

High energy bills

Your furnace and AC run overtime replacing the heating and cooling that leaks straight out the top of your home.

Ice dams on the roof

Warm air melts roof snow; it refreezes at the cold eaves, backing up water under your shingles.

Below Ontario Building Code

Older insulation often sits well under today's R-50/R-60 standard, leaving comfort and savings on the table.

Air leaks & gaps

Openings around hatches, pipes and wiring let pests and outside air in — and dragged your insulation's performance down.

Questions

Attic insulation, answered

How do I know if my attic needs more insulation?

Common signs are cold or hot rooms, big temperature differences between floors, and rising energy bills. If your insulation sits below the top of the joists or looks thin and patchy, it's usually below today's standard.

What's the best type of insulation for an attic?

There's no single answer. Blown-in cellulose and fibreglass suit open attics — they fill gaps and offer great value. Spray foam works well in tight areas that need both insulation and air sealing. We recommend based on your attic's condition, budget, and goals.

How much attic insulation should I have?

In Ontario's climate we typically target R-50 to R-60 — roughly 14–18 inches of blown-in material, depending on the product. On the assessment we measure your existing depth, estimate the R-value, flag any bare spots, and recommend the top-up.

Can you add new insulation on top of what I have, or does it need removal?

Often we can top up over dry, stable existing insulation — that's more cost-effective and less disruptive. Removal is the right call if the old material is wet, moldy, contaminated by rodents, or compressed, since those trap moisture and hurt performance.

What's the difference between insulation and air sealing — do I need both?

Insulation slows heat flow; air sealing stops warm indoor air from leaking into the attic through gaps around hatches, lights, pipes, and wiring. In Ontario winters, unsealed air causes condensation, frost, and mold. Treating the attic as a system — sealing, insulating, and checking ventilation — gives far better results.

Is attic insulation a DIY project?

You can, but doing it right means managing air sealing, ventilation, and moisture in a tight, dusty space around wiring, fans, and recessed lights — with clearances near chimneys and heat sources. A specialist brings the right equipment, building-science know-how, single-day completion, and documentation of exactly what was done.
