Should I block the vents to stop drafts?

No. The attic is meant to run close to outdoor temperature so the roof deck stays cold. Blocking soffit vents causes exactly the ice damming people add insulation to prevent.

How much insulation should my attic have?

It is settled depth and even coverage that decide performance, not the product name. We set depth markers before blowing so the result is measurable, and check the corners rather than just the area near the hatch.

How do I know I got the depth I paid for?

We leave depth markers through the attic so the installed depth can be read off by anyone afterwards. Depth is easy to claim and hard to check once the hatch is closed, which is exactly why we mark it.

Do you insulate over an addition or a vaulted ceiling?

Those need looking at specifically rather than quoting an average depth. Shallow attics, cathedral sections and knee walls are usually the coldest rooms in an Strathearn house and the parts a general top-up misses.

Can you just blow on top of what is already there?

Usually yes, if the existing insulation is dry, undisturbed and not contaminated. If it is wet or shows rodent activity it comes out first, because topping over that seals the problem in rather than fixing it.

Cellulose or fibreglass?

Both work when installed to depth with the ceiling sealed underneath. Cellulose is denser and resists air movement better; fibreglass is lighter and settles less. We pick based on what is already up there and tell you why.

Attic insulation in Strathearn: air seal first, then blow

The most common mistake in an Strathearn attic is blowing insulation over an unsealed ceiling. Warm moist air keeps rising through pot lights, top plates and the hatch, and it carries moisture into cold insulation where it condenses. We air-seal the penetrations first, then insulate.

Baffles kept clear so the soffit vents still breathe

Bathroom and kitchen fans venting into the attic

Found more often than you would think

In older Strathearn homes a bathroom fan is frequently ducted into the attic space rather than through the roof or soffit. It dumps warm wet air straight into the coldest part of the house.

Why it matters before insulating

Burying that under fresh loose-fill hides a moisture source that will show up as frost and staining. If we find one we tell you, because it needs correcting first — insulation on top of it makes it harder to reach and harder to diagnose.

What we see in Strathearn

In Strathearn the drywall work is plaster and lath repair, popcorn and stipple ceiling removal, careful patching into original surfaces. We confirm what your home actually needs on site, in writing, before anything starts.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Strathearn homeowner has laid plywood across the joists for storage, the insulation beneath is squashed to joist depth. That strip performs at a fraction of the rest of the attic.

Options

Either the storage area is raised on a platform above the finished insulation depth, or it is accepted as a deliberately weaker zone kept as small as possible. What does not work is topping up around it and pretending the platform is not there.

Ice damming and what the attic has to do with it

A heat problem, not a gutter problem

Ice at the eaves on an Strathearn roof usually means heat is escaping into the attic, melting snow on the upper roof, and that meltwater refreezing over the cold overhang.

Where the fix actually is

More heat tape rarely solves it. Sealing the air leaks and getting even insulation coverage right out to the eaves is what lowers the deck temperature. That is why we look at the attic when someone calls about ice, not at the roofline.

What we can and cannot tell you about savings

Honest about the number

We will not quote you a percentage off your heating bill. It depends on your current depth, your air leakage, your windows, your furnace and how you heat the house.

What we will say

What the attic has now, what it would have after, and where the leaks are. Those are things we can measure and show you. A savings figure from a contractor who has not seen your utility bills is a sales number, not an estimate.

Insulating a Strathearn attic with knob-and-tube or old wiring

Stop and check first

Some older Strathearn homes still carry active knob-and-tube wiring in the attic. Burying it in insulation is not something we do — it needs an electrician to assess and usually to replace before the attic is filled.

Why we raise it

It is the kind of thing found halfway through a job, and it is far cheaper to find at the quote. If we see it, we tell you and we stop until it is dealt with.

Depth is the whole number

What you are buying

Attic performance is almost entirely a function of settled depth and even coverage. Two attics with the same product can perform very differently.

How we handle it

Depth markers are set before blowing so the result is measurable rather than asserted, and the Strathearn attic is checked at the corners rather than only where the hatch is. An attic that is deep in the middle and thin at the perimeter is the usual finding.
