Have questions about insulation? You’re in the right place! Here, you’ll find answers to common questions and learn more about our services.
Uneven temperatures, rooms that are uncomfortable in summer or winter, and visibly thin or uneven attic insulation can all be reasons to take a closer look. These problems can also involve air leaks, ventilation, or your heating and cooling system.
We can evaluate the accessible attic and discuss whether additional insulation or other preparation would make sense.
Often, yes. Existing insulation does not automatically need to be removed before more is added. Its condition matters: wet insulation, pest contamination, or other damage may need to be addressed first.
We also consider air-sealing access and attic ventilation before recommending a top-up.
No. Age alone does not mean insulation needs to be removed. Removal may be appropriate when insulation is wet, contaminated, damaged, or preventing necessary work.
If a leak or pest problem has affected the insulation, the underlying problem should be corrected before replacement insulation is installed.
What’s the difference between open-cell and closed-cell spray foam?
What’s the difference between open-cell and closed-cell spray foam?
Open-cell foam is lighter and generally provides less R-value per inch. Closed-cell foam is denser, provides more R-value per inch, and has lower vapor permeability at appropriate thicknesses.
The right choice depends on the location, available space, moisture conditions, and the design of the wall or roof assembly. We install both types and can explain which fits your project.
Each material has applications where it makes sense. Spray foam can provide insulation and air sealing when installed at the required thickness. Blown-in cellulose is often a practical choice for accessible attic floors, while fiberglass batts can suit open framing.
We’ll consider your building, budget, and goals when recommending materials. Some projects benefit from using different insulation types in different areas.
How thick should spray foam insulation be?
here isn’t one correct thickness for every project. The recommendation depends on the specific foam product, required thermal performance, framing depth, and moisture-control needs.
Walls, rooflines, rim joists, and crawlspace walls can require different approaches. Your estimate should identify the foam type and installation thickness.
Can you spray foam a cathedral ceiling or roofline?
Yes, depending on the roof assembly and project requirements. Cathedral ceilings and insulated rooflines need careful planning for thermal performance, moisture control, and whether the assembly will be vented or unvented.
For new construction, we can coordinate the insulation scope with your builder before installation.
Do we need to leave the house during spray foam installation?
Plan for occupants and pets to be out of the designated work and restricted areas during spraying and for the required period afterward. Depending on the project, this may mean leaving the building.
The timing depends on the specific product, ventilation, and installation conditions. We’ll discuss those requirements before the job so you can plan accordingly.
What are attic baffles, and do I need them?
Baffles help maintain an airflow path from soffit vents into a vented attic while keeping insulation from blocking that path.
Whether you need new or replacement baffles depends on your roof design, existing ventilation, and insulation layout. We’ll evaluate these conditions as part of planning the attic work.
With unvented assembly, they aren’t needed. If still unsure, we’ll discuss more at the estimate.

The cost depends on the size of the area, insulation type, required thickness, access, and preparation involved. Removing old insulation, sealing air leaks, or installing attic ventilation baffles can also affect the total.
Your property address, contact information, and a short description of the project are a good starting point. Photos, approximate measurements, and details about existing insulation can also help.
For new construction or larger projects, floor plans and the builder’s insulation specifications are useful. You don’t need exact measurements to contact us.
Yes. We work on existing homes, remodels, additions, and new construction. We also insulate garages, pole barns, and commercial spaces. The right approach depends on how the building is constructed and how the space will be used.
