Why Air Duct Sealing Matters
Even small cracks or gaps in your ductwork can cause up to 30% air loss, forcing your HVAC system to work harder and increasing energy costs. Proper sealing keeps conditioned air where it belongs—inside your living spaces.

FAQs for Attic & Crawl-Space Insulation Revitalization in Tukwila
What are the most common reasons insulation stops working well in Tukwila homes?
We frequently find settled attic insulation, gaps around penetrations, and crawl-space insulation that has absorbed moisture or pulled away from framing. Revitalization restores coverage and targets the air leaks that cause drafts and energy loss.
Can you help if our crawl space has humidity, musty odor, or signs of past water?
Yes. We focus on moisture control first when needed, using options like vapor barrier upgrades, sealing entry points that pull damp air upward, and ventilation corrections. This helps protect the new insulation and reduces odor over time.
Do you inspect and improve attic ventilation before adding new insulation?
Absolutely. Proper ventilation helps prevent trapped moisture and keeps insulation performing as designed. We review airflow and recommend adjustments so the attic stays healthier and more stable.
