Insulating Burlington homes on river ground
Thermal Bellingham Insulation Company insulates and air seals homes in Burlington, and most calls here come from drafty older houses with cold floors and thin attic insulation. Most of the city sits in the Skagit River floodplain, which shapes both the permit questions and what we find under your floor.
What a Burlington job turns on before we start
Permits in Burlington go through the city's Permit Center, which handles every land use, construction and infrastructure permit in the city. Since so much of Burlington is floodplain, the city has its own permit rules for work there, so before we schedule anything I check with the city about your address and walk you through whatever they need from us or from you. If your job needs a permit, the start date waits on it.
Two checks are worth doing before you hire anyone here. Washington requires every construction contractor to register with the state Department of Labor and Industries, and the city requires a business license for anyone doing business inside city limits. We're licensed and fully insured, so ask us about both, the same as you would anyone else.
We get the same kinds of calls here that we get in Mount Vernon and up in Birch Bay: drafty older rooms, cold floors over crawl spaces and attics with a few tired inches. Your price turns on how much area we cover, what's already there and whether old material has to come out first. The schedule turns on that and any permit, and your written plan from the estimate puts each step in order.
Our usual Burlington jobs

Insulation services for Burlington homes
Most Burlington houses need a mix of these, usually starting under the floor or in the attic, and the order we do them in matters as much as the material.
Spray foam insulation
In a room over the garage, spray foam seals the air and insulates in one pass, which loose fill can't do.
Attic insulation
Most attics we open in Burlington have a few tired inches, often thinnest at the edges where cold gets in.
Blown-in insulation
Blown-in insulation, loose fill sent through a hose, tops up an attic quickly, and we keep it off the eave vents.
Home insulation
For a drafty older house, I look at the attic, walls and floor together and plan the fixes in order.
Insulation removal
Insulation that's been soaked or holds droppings comes out before anything new goes in, or the problem just stays.
Crawl space insulation
Cold floors in Burlington usually trace back to a crawl space with missing or sagging insulation under the boards.
Wall insulation
One outside room that never warms up often has wall cavities that were left empty or have settled over time.
Air sealing services
Air sealing, closing the gaps before we insulate, stops drafts through wiring holes and plumbing runs in older Burlington homes.
Basement insulation
Basement walls on low ground need material that copes with damp, so we look for water before choosing anything.
Closed-cell foam insulation
Closed-cell foam, a dense foam that also blocks moisture, suits rim joists and crawl space walls close to wet ground.
Open-cell foam insulation
Open-cell foam is lighter and softer, and it fills rooflines and interior walls in the dry parts of the house.
Commercial insulation
Landlords and property managers here get the same checks-first order, scheduled around tenants and the hours they keep.
Crawl space vapor barrier
A heavy plastic sheet over crawl space dirt keeps ground moisture away from your floor, which matters on ground this low.
Vapor barrier installation
When a remodel opens walls or floors, we add a vapor barrier so moisture from inside doesn't settle in the framing.
Attic air sealing
Can lights, plumbing stacks and the hatch leak warm air into Burlington attics, so we seal them before any insulation goes up.
Retrofit insulation
Retrofit work adds insulation to a finished house through the attic, crawl space and small openings, without gutting the rooms.

Burlington insulation questions
These are the questions we hear from Burlington homeowners about permits, crawl spaces and price. If yours isn't here, call and ask about your own house.
How do I find out if my insulation job in Burlington needs a flood permit?
You check the job against the city's floodplain rule, which usually requires a flood development permit for construction, clearing, grading, excavation or other development in floodplain areas, with minor improvements left out. Whether a given insulation job falls under it depends on the work, so I settle that for your address before your job goes on the calendar.
How long is a building permit good for in Burlington, WA?
A Burlington building permit becomes void if work doesn't start within 180 days of when it's issued, or if work stops for 180 days after it starts. If your job needs one, we plan the start date around that window.
What building code applies to insulation work on a house in Burlington?
Burlington follows the state building code, which means the International Building Codes with Washington's own amendments. The city's Building Department does the plan review and inspections under that code.
What paperwork should a contractor give me for a home insulation job in Burlington?
Washington requires contractors to give you the state's disclosure notice to customers on every home job of $1,000 or more. If a contractor doesn't bring it up on a job that size, ask for it, and you'll also get our written plan listing each step.
What causes cold floors in a Burlington house with a crawl space?
Cold floors usually come from insulation under the floor that's missing, sagging or wet, plus air moving through gaps into the crawl space. On ground as low as Burlington's we check for moisture first, because new insulation over a damp crawl space just holds the same problem, and a vapor barrier over the dirt often comes before anything else.
How much does insulation cost in Burlington, WA?
Your price comes from the written plan after I've seen your house, and it mostly depends on how much area we cover, what's already there and whether old insulation has to come out first. Spray foam costs more because it seals and insulates at once, but sealing the gaps and topping up loose fill usually gets you more for the money, unless your ductwork runs through the attic.
