Spray Foam Insulation in Wenatchee, WA
Spray foam does two jobs at once: it insulates and it air seals. That combination is why we use it on rim joists, crawl space walls, cathedral ceilings, shop buildings, and hard-to-detail assemblies where batts alone leave gaps. L&S Contracting Services brings our own rig to jobsites across Wenatchee, East Wenatchee, Malaga, Cashmere, Leavenworth, and the surrounding Chelan and Douglas County area.
Where spray foam earns its keep
North Central Washington swings from hot, dusty summers to cold winters, and most of the comfort complaints we hear trace back to air movement rather than a missing inch of insulation. Rim joists, top plates, cantilevers, knee walls, and crawl space perimeters leak air even when the batts look fine. Spray foam bonds directly to the framing and sheathing, so it fills the odd shapes and seals the seams at the same time. In crawl spaces and shops it also helps control the movement of moist air into cold framing.
How we approach a foam job
We look at the assembly before we quote it. That means checking what the cavity is doing, whether there is existing insulation to remove, how the space is vented, and where the air barrier is supposed to live. On new construction we schedule foam before drywall and coordinate with framing, plumbing, and electrical so penetrations are in place first. On existing buildings we plan access, protect finished areas, and confirm ventilation during and after the application. Thickness is set by the assembly and the code path the project is following, not by a one-size number.
Foam plus the rest of the envelope
Spray foam is often part of a package rather than the whole answer. A typical project might combine foam at the rim joist and crawl space perimeter with blown-in or batt insulation in the attic, plus air sealing at penetrations. Because we handle insulation, air sealing, vapor barriers, and blower door testing, we can pick the right material for each assembly instead of foaming everything by default.

FAQ
Common questions
- Is spray foam better than batt insulation?
- It depends on the assembly. Spray foam is a strong choice where air sealing matters most, such as rim joists, crawl space walls, and irregular framing. Batts and blown-in insulation still make sense in open attics and standard stud bays, and many projects use a combination.
- Can spray foam be installed in an existing home?
- Yes. We install spray foam in existing homes, crawl spaces, garages, and shops. Existing insulation sometimes needs to be removed first so the foam can bond to clean framing and sheathing.
- Does spray foam help with dust and drafts?
- Sealing air leaks reduces the uncontrolled airflow that carries dust and creates drafts, which is one of the most common reasons Wenatchee-area homeowners call us about foam.
- Do you spray foam for builders?
- Yes. We schedule spray foam for builders and general contractors on new construction and remodel projects, and we can pair it with blower door testing on the same job.
