Can I add over the old insulation?

Usually yes, if it is dry, even and uncontaminated. If it is wet, compacted, rodent-affected or hiding unsealed penetrations, removing it first is worth the cost, and we tell you which one we found.

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.

Why does my Lynnwood attic frost up in winter?

Almost always warm moist air leaking up from the house through pot lights, top plates or the hatch, then condensing on cold sheathing. More insulation on its own does not fix it — the leaks have to be sealed first.

Do I need to seal before adding insulation?

Yes, and it is the part most often skipped. Warm moist air leaking from the house frosts the roof deck and wets the insulation. Blowing over unsealed pot lights and top plates buries the problem instead of 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.

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.

Blown-in attic insulation in Lynnwood, sealed before it is filled

The most common mistake in an Lynnwood 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.

Blown-in loose-fill to the depth your permit specifies
Depth markers left in place so the result is verifiable
Air sealing at pot lights, top plates and the attic hatch
Attic hatch insulated and weatherstripped
Existing insulation levelled before the top-up
Baffles kept clear so the soffit vents still breathe

Attics over additions and vaulted areas

The awkward spaces

An Lynnwood addition often has a shallow attic, a cathedral section or a knee wall, and those areas are where insulation is thinnest and access is worst.

Why they matter disproportionately

They are frequently the coldest rooms in the house, and they are the parts a general top-up misses because the blower cannot reach them. We look at them specifically rather than quoting an average depth across the whole ceiling.

Lynnwood drywall in context

About Lynnwood

A mature suburban neighbourhood, Lynnwood began its development as a part of the Town of Jasper Place during the 1950s.

What we see in Lynnwood

In Lynnwood 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.

Why air sealing comes before insulation in Lynnwood

Insulation does not stop air

Batt and loose-fill slow heat transfer; neither stops air movement. In an Lynnwood attic warm moist household air rises through pot lights, top plates and the hatch, passes straight through the insulation and condenses when it hits the cold deck.

What that looks like later

Frost on the underside of the sheathing in February, then staining on the ceiling in spring. Sealing the penetrations first is the difference between insulation that works and insulation that becomes the problem.

The attic hatch nobody insulates

A hole in the ceiling

An uninsulated, unsealed hatch is a direct opening between the heated house and a cold attic, and it is often the single worst detail in an otherwise good Lynnwood ceiling.

Simple fix

An insulated cover with weatherstripping and a dam around the opening so blown insulation does not spill through when it is opened.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Lynnwood 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.

Ventilation is not optional up there

Cold attic, by design

An Lynnwood attic is meant to run close to outdoor temperature so the roof deck stays cold and snow does not melt and refreeze at the eaves.

The failure it prevents

Blocking soffit vents with insulation causes exactly the ice damming people add insulation to prevent. Air sealing the ceiling below and keeping the vents clear are two halves of the same job.

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in Lynnwood ceilings need clearance and cannot be buried. Newer IC-rated fixtures are built to be in contact with insulation.

What we check

We identify what is installed before blowing. Where fixtures cannot be covered, they need boxing or replacing — and each one is also a significant air leak, so they are usually the first thing sealed regardless of type.
