Answers to Common Questions About Spray Foam Insulation in Mercer Island

What type of spray foam is best for Mercer Island homes?

Closed-cell spray foam is typically best for exterior walls, crawl spaces, and basements due to its moisture-resistant properties, while open-cell foam is ideal for interior walls and sound control. Our team will recommend the right type during your free assessment.

How long does spray foam insulation last?

Spray foam insulation can last for decades—often 20+ years—without needing replacement, provided it's installed correctly. It doesn't sag, settle, or degrade like traditional insulation.

Is spray foam insulation safe for indoor air quality?

Yes, once cured, spray foam is inert and non-toxic. We follow industry best practices to ensure safe installation and minimal disruption to your home.

Does spray foam insulation help with noise reduction?

Absolutely. Open-cell spray foam is especially effective at sound dampening, making it great for interior walls, media rooms, and shared walls in townhomes.

Can spray foam be used in older Mercer Island homes?

Yes, spray foam is often used during renovations or upgrades in older homes. It seals leaks and improves efficiency better than traditional options like fiberglass or cellulose.

What areas of a home benefit most from spray foam?

Key areas include attics, crawl spaces, basements, exterior walls, and garages. These are common sources of heat loss in Mercer Island homes.

Will spray foam help lower my energy bills?

Yes! Many customers report savings of 20–40% on heating and cooling costs after installation. It works by sealing air leaks and improving thermal performance.

Is spray foam insulation eco-friendly?

Spray foam can help reduce your carbon footprint by lowering your home's energy usage. We use low-VOC, environmentally friendly products that comply with Washington’s green building standards.

How soon can you install insulation in Mercer Island?

In most cases, we can schedule your free assessment within a few days and complete installation shortly after, depending on the scope of the project.
