West Des Moines Blown-In Insulation
Cellulose and fiberglass blown into West Des Moines attics and packed tight into old wall cavities. Sealed first, scanned after, and written down so you know what you got.
Loose fill goes where hands cannot.
Blown-in is how you insulate the parts of a house nobody can reach. An attic floor full of wires, bracing and odd angles never takes batts cleanly, and there is no getting behind finished plaster at all. A hose solves both. It fills what is actually there instead of what a rectangle of fiberglass assumes is there.
West Des Moines gives us two very different versions of that job. On the Valley Junction side we are working on houses built around 1900 whose walls are simply hollow, stud bay after stud bay of open air behind the siding. Out toward Westridge and the newer streets the walls are fine and the attic is the problem, because thirty-plus years of settling has left a blanket that measures a lot thinner today than the day it went in.
Christian looks at the assembly before anybody talks about product. Sometimes the answer is a top-up over what is already up there. Sometimes it is dense-packing the walls and leaving the attic alone until spring. We would rather tell you the smaller job is the right one than sell you both.
Which material, and why we care.
Weight is the whole argument
Cellulose is ground-up paper treated with borate. Packed into a wall bay at the right density it stops air from circulating inside the cavity, which is most of what makes an old wall feel cold. Blown fiberglass is lighter, needs more depth for the same rating, and will not hold a wall bay tight.
So walls get cellulose, essentially always. Attics can go either way. We reach for fiberglass when ceiling framing is light or when a homeowner does not want paper over their drywall. Neither feeds mold, neither interests rodents. This is a density decision.
Settling, told straight
Cellulose settles. Anyone who says otherwise is selling something. The amount is published by the manufacturer and it is predictable, so we install past your target depth and let it come down onto the number. An attic blown to look right on day one is an attic that is short by February, and the difference is real money on a Polk County heating bill.
Depth is also worth nothing if it is uneven. A mound by the hatch with thin edges at the eaves leaks heat along the perimeter, which is where ice dams start. We rake it flat corner to corner, leave depth rulers standing in the material, and photograph them. The settled number is something you can go check yourself.
How a West Des Moines job actually runs.
Walk it first
We measure what is up there now, check whether it is dry, and find out what the walls are hiding. Woodward is about thirty-five minutes out, so we come look before we quote anything.
Seal the ceiling
Can lights, plumbing stacks, top plates and the attic hatch get sealed before a single bag opens. Baffles go in at the eaves so the soffit vents stay breathing.
Open the walls quietly
On dense-pack work we pull a course of siding and drill into each bay from outside. The plugs go back under the siding, so when we are done your exterior looks untouched.
Fill it tight
Walls get packed until the hose pushes back and the machine loads up. Attics get blown past target and raked level so the settled depth lands where it should.
Scan and prove it
An infrared camera on a cold day shows every bay. A skipped one glows against its filled neighbors. If we find one, we open it and finish it while we are still on site.
Clean up and hand it over
Depth report, product paperwork, scan images. Old material leaves on our trailer, the drive gets swept, and Christian walks the finished work with you.
Two neighborhoods, two different problems.
Valley Junction walls
Houses from around 1900 were framed before anybody insulated walls at all, so the bays behind the siding are open. Dense-packing them is the single biggest change you can make to how one of those homes feels, and you do it without disturbing a single original wall inside.
Westridge attics
Homes built in the 1980s went up with what passed for adequate then, and it has been settling ever since. A fresh layer over sound existing material brings the ceiling back to current recommendations in a day, and it is the cheapest comfort you will ever buy.
The north wind
There is nothing between West Des Moines and open prairie to slow a January wind down. A packed wall bay does not let that air wander through the cavity, and the room on the windward side stops feeling like a different house than the rest.
Proof, not promises
Insulation is the one upgrade you pay for and then never see again. That is why we hand over scan images and ruler photos. You should not have to take our word for what is behind your siding.
We run West Des Moines on the regular Polk County route.
Woodward to West Des Moines is a straight shot, and we group metro work so travel does not inflate anybody’s number. Call and we will usually name a window on the first conversation.
