Cold floors in February, a bedroom that never keeps up, and a heat pump that runs constantly usually point to the same place — the attic and the crawlspace, not the equipment. An insulation contractor in Battle Ground WA can often fix that for a fraction of what a new system costs. Request a few assessments and see what your house actually needs.
Blowing another twelve inches of insulation over a leaky attic floor is the most common half-measure in this trade. Warm moist air rises through can lights, top plates, the attic hatch, and the chase around the flue, carrying heat and moisture straight into a cold attic. Seal those penetrations first, then bring the insulation up to depth. The order matters more than the R-value on the bag.
Under most homes here you'll find batts that have sagged out of the joists, a vapor barrier torn by decades of foot traffic, and uninsulated ducts and pipes. Reinstalling the ground barrier properly, supporting the floor insulation so it stays in contact, and insulating the duct runs is unglamorous work that makes an immediate difference to how the floors feel.
For most homes in this area, the ranked list is air sealing, attic insulation, crawlspace and duct work, then windows — usually a long way down. A blower door test tells you where you stand rather than guessing. Utility conservation programs in Clark County have historically offered incentives on weatherization measures, so ask your contractor what's currently available before signing.

In a climate with eight wet months, insulation problems show up as moisture problems: condensation on cold surfaces, mold at the rim joist, and wet batts that have stopped insulating altogether. That's why crawlspace ground cover and controlled ventilation are treated as part of the insulation job here rather than a separate concern.
Washington's energy code sets minimum insulation levels for new work and for many retrofits, and the contractor should be able to tell you what your assemblies are being brought to. Insulation retrofits often don't require a building permit on their own, but any work touching electrical, structural framing, or ventilation may. L&I registration applies as it does to every trade here.
Properties on the higher ground toward Yacolt and east of town run colder and see snow the valley misses, and homes on open parcels lose more to wind washing through soffit vents and unsealed rim joists. Baffles at the eaves and a proper wind block at the perimeter matter more here than on a sheltered in-town lot.
Blown attic insulation commonly runs $1.75 to $3.50 per square foot depending on existing depth and access, so a typical attic often lands between $2,000 and $4,500. Attic air sealing usually adds $700 to $2,000 and is the best value in the package. Crawlspace floor insulation with a new ground vapor barrier typically runs $3,000 to $7,000. Spray foam costs considerably more per square foot and is worth it in specific assemblies rather than everywhere. Ask for a blower door number before and after if the goal is measurable.
They sealed the attic penetrations before blowing insulation and explained why that order mattered. The upstairs finally holds temperature overnight.
New ground barrier and reinstalled floor insulation in the crawlspace. The kitchen floor is no longer painful to stand on in January.
Insulated the shop walls and the door before winter so the heater could keep up. They got the vapor retarder facing right for our climate, which I would have gotten backwards.
Look with a flashlight — if the insulation is level with or below the top of the ceiling joists, it's well short of current expectations. Uneven snow melt on the roof and warm spots on the ceiling are other tells. A contractor should measure depth in several places rather than eyeballing it from the hatch.
Both approaches work when done properly. Vented with a good ground barrier and insulated floor is the common, less expensive path here. Encapsulation with a sealed liner and conditioned air is more effective for damp spaces and ductwork but costs considerably more and needs to be done completely to be worth doing.
Usually, though the honest framing is comfort first and savings second. Homes here that go from minimal attic insulation and leaky ceilings to sealed and properly insulated commonly see meaningful reductions in heating runtime. Anyone promising a specific percentage before testing your house is guessing.
Sound fiberglass is typically left and blown over. It gets removed when it's contaminated by rodents, wet, or when the attic floor needs air sealing that can't be done through it. Removal and disposal is a separate line item and it's worth asking whether it's genuinely needed.
