What's included
What our spray foam insulation service includes
Every spray foam job includes the prep, the foam, the cleanup, and the verification. Here is what is covered in a standard scope, and where add-ons come in if your home needs them.
On-site inspection and scope
We inspect the attic, crawl space, rim joists, and any problem rooms with a thermal imaging camera and moisture meter. You get photos, a written scope with R-values and square footage, and an upfront price before we schedule the spray day.
Masking and ventilation setup
We mask windows, doors, and HVAC returns with Frog Tape and plastic, seal the work zone, and set up ventilation. Crews wear respirator masks and eye protection. Prep on a typical Milwaukie attic takes 45 to 90 minutes.
Closed cell or open cell foam
We carry both systems on the truck and spec the right one for each cavity. Closed cell for rim joists, crawl space walls, and anywhere moisture is a factor. Open cell for interior walls where sound control and cost matter more.
Trimming and cleanup
After the foam cures, we trim excess with a utility knife, vacuum debris with an insulation vacuum, and pull all masking. You get the space back clean, with no sticky overspray on surfaces or framing.
Blower door and thermal verification
We test before and after and give you the numbers. Most Milwaukie homes show a 20 to 35 percent reduction in air leakage. You keep the report for your records, resale, or Energy Star rebate paperwork.
Written summary and data sheets
You get a written summary of what was sprayed, the R-value achieved, and the product data sheet for the foam we used. If you ever need to show the work to an inspector or a buyer, it is all in one place.
Service overview
What spray foam insulation Milwaukie OR actually does
spray foam insulation Milwaukie OR is a two-part polyurethane product that is sprayed as a liquid and expands in seconds to roughly 30 to 60 times its original volume. It cures into a rigid or semi-rigid layer that bonds to wood, concrete, and metal, sealing the gaps where fiberglass batts and cellulose simply sit and let air move past. Closed cell foam lands around R-6.5 to R-7 per inch and doubles as a vapor barrier. Open cell foam runs about R-3.6 per inch and is the better pick for interior wall cavities where you want sound dampening and a lower material cost.
We see the same problems across Milwaukie: 1950s ranch homes in Oak Grove with bare rim joists, crawl spaces off Lake Road that pull damp air up through the floor, and bonus rooms over garages in Milwaukie Heights that never stay warm. A blower door test before and after tells the real story. Most homes we seal in Clackamas County drop 20 to 35 percent on air leakage, which shows up on your PGE bill the first cold month.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
How our spray foam insulation process runs
The process flexes to the condition, but these checkpoints keep decisions clear.
Phone assessment
Call (855) 947-9500 and we ask the right questions: home age, problem rooms, attic or crawl space access, and whether you have had water intrusion. Most Milwaukie jobs get a same-day or next-day on-site visit. We give you an upfront price before we start, not a surprise invoice after.
On-site inspection
We walk the attic, crawl space, and rim joists with a thermal imaging camera and moisture meter. A stud finder and utility knife help us map cavities. You get photos of what we find and a written scope with R-values and square footage, usually within 24 hours.
Prep and masking
Foam overspray is sticky. We mask windows, doors, and HVAC returns with Frog Tape and plastic, seal off the work zone, and set up ventilation. Crews wear a respirator mask and eye protection the entire time. Prep on a typical attic takes 45 to 90 minutes.
Spray and cure
We spray in 2-inch lifts so the foam cures evenly and does not overheat. A 1,000-square-foot attic takes about 3 to 5 hours with a two-man crew. You stay out of the space for 24 hours while it cures and vents, then it is ready to walk on or cover.
Walkthrough and cleanup
We trim excess foam with a utility knife, vacuum debris with an insulation vacuum, and pull all masking. Then we walk you through the finished work, show you the before-and-after thermal images, and leave you a written summary with the R-value achieved and the product data sheet.
Tools & methods
Tools and methods we use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
spray foam gun
Heated, proportioning gun that mixes the two foam components at the tip and lays down an even 2-inch pass. We keep spare tips on the truck so a clog never stalls the job.
thermal imaging camera
Shows us where air is moving before we spray and confirms the seal after. It is how we find the bypasses you cannot see with a flashlight.
moisture meter
Reads framing and subfloor moisture before and after. We will not foam over wet wood, and we document the readings so you know the cavity is dry.
insulation blower machine
Used for blown in insulation and cellulose over foamed attic decks. It fills the open areas evenly so you get consistent R-value across the whole floor.
respirator mask
Required PPE for every crew member during spray and cure. Foam isocyanate is not something you want to breathe, and we do not cut corners on safety.
insulation vacuum
Cleans up foam trimmings and old insulation debris. It is the reason our job sites look clean when we leave, not like a construction zone.
stud finder and utility knife
Used to map cavities and trim cured foam flush with framing. Small tools, but they make the difference between a neat job and a messy one.
Use cases
When Milwaukie homeowners call for spray foam
These examples show how the service framework adapts rather than forcing every call through one repair.
Milwaukie Heights bonus room becomes usable
A bonus room over an attached garage that stayed 10 degrees colder than the rest of the house. The floor cavity was open, and the knee walls had compressed batts. → We sprayed closed cell in the floor cavity and open cell in the knee walls. The room now holds 68 degrees with the door closed, and the homeowner uses it as a home office year-round.
Lake Road crawl space dried out
A crawl space with damp joists, a torn vapor barrier, and mold starting on the subfloor. Moisture meter readings were 19 percent on the floor framing. → We removed the old insulation, treated the framing, foamed the walls and rim joists with closed cell, and installed a sealed vapor barrier. Readings dropped to 11 percent and stayed there through the wet season.
Problems we solve
Problems spray foam insulation solves in Milwaukie
Most insulation calls start with a symptom: a cold room, a high bill, a damp crawl space. Here are the problems we fix most often in Milwaukie homes.
Drafty rooms and cold floors
We foam the rim joists, band joists, and any cantilevered floor cavities. Closed cell foam bonds to the framing and seals the gap that fiberglass batts leave open. Most rooms feel different the first cold night after the spray cures.
High energy bills every winter
We run a blower door test, find the bypasses, and foam them. Top plates, recessed lights, duct chases, and plumbing penetrations all get sealed. You get the before-and-after numbers so you can see what changed.
Moisture and mold in crawl spaces
Spray foam insulation for crawl spaces in Milwaukie means foaming the walls and rim joists with closed cell, sealing the vents, and installing a vapor barrier. We check with a moisture meter before and after so you know the cavity is dry.
Ice dams and roof damage
We seal the attic bypasses that let heat escape into the roof deck. With the attic running cold, snow melts evenly and ice dams stop forming. We also check attic ventilation to make sure the assembly can dry.
How much does spray foam insulation cost in Milwaukie OR?
Most Milwaukie attic and crawl space jobs run $1,800 to $5,500 in 2026, depending on square footage and whether you choose open cell or closed cell. Rim joist-only work often lands between $600 and $1,400. We give you a written price after the on-site inspection, and that number does not move unless you add scope.
Is spray polyurethane foam insulation worth it in Milwaukie Oregon?
Yes, if you plan to stay in the home more than three or four years. The average Milwaukie house we seal cuts air leakage by 20 to 35 percent, which typically saves $300 to $700 a year on heating and cooling. Combined with better comfort and moisture control, most homeowners break even inside five years.
How long does spray foam insulation last in Milwaukie?
Properly installed spray foam lasts the life of the building, 50 years or more. It does not sag, settle, or compress the way fiberglass batts do. The main threats are UV exposure, which only matters in open attics, and long-term water intrusion. We address both during install so the foam stays sealed.
Can spray foam insulation be installed in Milwaukie OR in winter?
Yes. We install year-round in Milwaukie, including through the wet, cold months from November to March. Substrate temperature matters more than outdoor air, and we heat the space or use winter-grade formulations when needed. Foam cures fine down to about 20 degrees Fahrenheit with the right setup.

attic insulation
Spray foam attic insulation Milwaukie OR pairs with our attic work to seal top plates, recessed lights, and duct chases. Most Milwaukie attics get foam on the flat surfaces and blown-in insulation over the top for a combined R-49 to R-60.
garage door insulation
A foamed garage ceiling holds heat better, but the door itself is still a weak point. We add foam board or a door kit so your bonus room over the garage stays warm and your attached garage does not pull heat from the house.
fiberglass insulation
Fiberglass batts still have a place in interior walls where foam is not needed. We often combine the two: foam at the rim joist and top plate, batts in the field, so you get air sealing where it counts without paying foam prices everywhere.Ready when you are
