The flat card
Flat means flat. If the loft needs a second hose run or the hatch takes an hour, that is our day, not your money. The only extra we ever quote is a skip, and only when the loft is full of the previous owner’s treasures.
Attic top-up to R-60$2,150 flat
Cellulose over what is there, dams and baffles set, hatch sealed — houses to 1,400 sq ft
Attic top-up to R-60$2,850 flat
The same day, houses 1,400 to 2,400 sq ft
Attic from bare joists$3,400 flat
Empty loft blown to R-60 in one pass, includes air sealing the ceiling plane
Dense-pack walls$460 / unit
Per 100 sq ft of wall, holes plugged and patched — most rooms are two units
Rim-joist foam$980 flat
Two-part foam on the box sill, perimeter to 200 lin ft
Blower-door readings$0
Before and after, printed on the invoice — included, never itemised
We vacuum first
Old lofts hold sixty years of dust, wasp paper and the odd soda bottle. Every Cold Hollow blow starts with the vac — because cellulose laid over detritus is a mattress, not insulation.
The price is the price
The survey call fixes the number, the number goes on the card, and the invoice repeats it at the top. Nobody in nine years has paid a cent over the quote, because nobody has been asked to.
Both readings printed
Blower door before we start, blower door when we pack up, both numbers on your invoice. You will know exactly what the day bought, in the only units that matter.
The process
A blow day, start to finish
Same shape every time — the survey call in the week before, the van at eight, the readings at each end.
The survey call
Ten minutes, free
Loft size, access, what is up there now. The flat price is fixed on the call and confirmed by message before we hang up.
8:00
The van arrives
Runners down the hall, dust sheets over everything, hose through the hatch. The first blower-door reading happens before the machine comes off the truck.
9:00
Vac, dams, baffles
The loft cleaned, dams set at every light and the hatch, baffles keeping the soffits breathing — the hour that makes the blow worth having.
13:00
The blow
Cellulose to a settled R-60, joists disappearing as it goes. Most houses are blown by mid-afternoon; the big bare-joist jobs go to five.
The card
Read and sign
Second blower-door reading, both numbers printed, the insulation card pinned to the hatch. We vacuum the hall on the way out.

Recent blow days
Photographed at the second blower-door reading, same day, every job.
Quoted $2,850 on the phone Tuesday, blown Thursday, invoiced $2,850 on Friday. There is a number printed at the bottom labelled “CFM50 before” and one labelled “after”, and the gap between them is the warmest thing in the house.
They vacuumed out a loft nobody had been in since the sixties — two wasp nests, one sled, a hornet colony the size of a football — then blew R-60 over the clean deck. The upstairs bedroom stopped being a rumour that same night.
Every insulation outfit that called back wanted to “assess” for two hundred and something. Cold Hollow asked ten minutes of questions and gave me a flat number that did not move. That is the entire review.
The flat-card five
Straight answers
If your question is not here, the shop line at the bottom answers seven to five — and quotes flats over the phone.
What if my loft is bigger or stranger than the card?
The survey call exists for exactly that. About one house in twenty needs a custom line — a cathedral ceiling, a half-storey with knee walls — and we say so on the call, in a number, before anyone drives out. The card price still governs everything the card covers.
Why R-60 when code says R-49?
Because the extra four inches is a bag count, not a second job, and at R-49 the attic still carries off a quarter of the heat. Blowing to R-60 costs you a little more cellulose and nothing else — so that is what the hose is set to, every time.
Cellulose or fibreglass?
Cellulose, always — 3.5 lb/ft³ dense where it is packed, blown deep where it is loose. It fills around joists and wiring the way a liquid would, holds its R-value in cold that makes fibreglass droop, and it is mostly recycled newspaper, which the valley has plenty of.
Can you do the walls too?
Yes — dense-pack by the 100-square-foot unit, $460 flat per unit, holes plugged and patched the same day. Most rooms are two units. The survey call prices the whole house in units, and the card rules apply: the number does not move.
What about the rebates?
The invoice prints in the format the utility programs ask for, and we file the paperwork for you. Where the program allows, the rebate comes off the invoice at the start rather than arriving as a cheque in the spring.
