Insulation Contractor Sunnyvale, CA

Don’t Try to Replace Insulation on Your Own

Though it may seem like a straightforward task, replacing insulation requires specialized knowledge, tools, and safety precautions. Removing old insulation exposes you to dust, allergens, and even mold spores that can affect indoor air quality. These contaminants, if disturbed, can spread throughout your home, creating unnecessary health risks. Additionally, without professional training, it’s easy to overlook insulation gaps or accidentally damage ducts, pipes, or electrical components in your attic or walls.

Our team at EM Energy and Air brings the experience and equipment needed to handle insulation removal and installation safely and effectively. We carefully remove old insulation, keeping contaminants contained and out of your living space. Once the area is prepared, we install new insulation with precision, achieving full coverage and eliminating gaps that can lead to energy loss. With our expertise, you get an efficient, worry-free installation that protects both your home and family.

We Handle All Types of Insulation

Each home has unique needs, and we offer a range of insulation types to provide the best results for your specific situation. Our options include blown-in fiberglass, cellulose, fiberglass batts, and mineral wool, each with its own benefits and applications. Blown-in fiberglass is a flexible, cost-effective option that fills tight spaces effectively. Cellulose, made from recycled materials, provides an eco-friendly choice that works well for attics and walls. Fiberglass batts offer dense, durable coverage ideal for walls and ceilings, while mineral wool provides extra fire resistance and soundproofing.

No matter the type of insulation you need, our team installs it with precision and care, maximizing energy efficiency and comfort. We work with you to select the best material for each area of your home, ensuring long-lasting results and reliable performance.

Full Range of Duct and Attic Services

Beyond insulation, EM Energy and Air provides a variety of duct and attic services to keep your home running smoothly. Each of these services complements our insulation work.

Attic Rodent Control

Attics can become a haven for rodents if not properly maintained. Rodents can damage insulation, chew on wiring, and create health hazards. Our attic rodent control service removes these pests and seals potential entry points to prevent future infestations, helping protect both your insulation and overall attic environment.

Ductwork and Duct Cleaning

Your ducts play a major role in maintaining your home’s air quality and energy efficiency. Over time, dust and debris build up inside the ductwork, reducing airflow and increasing strain on your HVAC system. We offer thorough duct cleaning services to clear out contaminants, improve airflow, and reduce allergens. If your ducts need repair or replacement, we handle that as well.

Cleaning and Disinfecting

Our cleaning and disinfecting services help remove mold, mildew, and other contaminants from your attic and ducts, contributing to a healthier home environment. This service is particularly valuable when combined with insulation replacement, as it allows us to address any existing issues before installing new insulation.

Roof Replacements

In addition to insulation, we also offer roof replacements to protect your home from leaks, drafts, and other issues that can impact your insulation’s effectiveness.

Frequently Asked Questions About Insulation in Sunnyvale

 

What areas of the home do you insulate most often?

We most commonly insulate attics, walls, and crawl spaces. Attics tend to be the biggest source of heat gain and heat loss, especially in older Sunnyvale homes, so they are often the first place we recommend addressing.

 

How do I know if my attic insulation needs to be replaced?

Signs include uneven temperatures, rising energy bills, dusty air, and insulation that looks compacted, dirty, or disturbed by pests. During a free inspection, we check depth, coverage, moisture exposure, and contamination to determine whether replacement makes sense.

 

What insulation materials do you recommend for Sunnyvale homes?

We install blown‑in fiberglass, cellulose, fiberglass batts, and mineral wool. The right choice depends on attic layout, framing, existing insulation, and budget. Blown‑in fiberglass is very common in attics due to its coverage and fire resistance.

 

Is blown‑in insulation better than fiberglass batts?

Blown‑in insulation is often better for attics because it fills gaps and irregular spaces more completely. Fiberglass batts work well in open wall cavities or during remodels where framing is exposed. Each material has a place depending on the application.

 

Do you remove old insulation before installing new material?

Yes. When insulation is contaminated by rodents, moisture, or excessive dust, removal is the correct approach. Removing old material allows us to clean the space, seal entry points, and install new insulation without trapping pollutants underneath.

 

Can insulation upgrades help my HVAC system perform better?

Absolutely. Proper insulation reduces heat transfer, which allows heating and cooling systems to cycle less often. This improves comfort, reduces energy use, and helps HVAC equipment last longer.

 

Is attic insulation replacement safe for homeowners to do themselves?

Insulation work often exposes dust, allergens, rodent waste, and mold spores. It also requires working around electrical wiring and ductwork. Professional installation keeps contaminants contained and avoids accidental damage to critical systems.

 

Do you seal air gaps during insulation projects?

Yes. Before installing new insulation, we seal common leakage points such as top plates, wire penetrations, duct chases, and attic access openings. This step improves performance and prevents conditioned air from escaping.

 

How long does insulation installation usually take?

Most attic insulation projects are completed in one day. Larger homes or projects that include removal, cleaning, and rodent proofing may take longer. We provide a clear timeline during the inspection.

 

Will new insulation help with indoor air quality?

Yes. Insulation reduces the movement of dust and outdoor pollutants into living spaces. When paired with air sealing and attic cleaning, many homeowners notice fresher air and fewer allergy symptoms.

 

Do you offer a warranty on insulation work?

We provide one of the strongest labor warranties in the Bay Area on insulation installations. Manufacturer warranties also apply to the materials used, giving homeowners long‑term confidence in the work.

 

Do you serve areas outside of Sunnyvale?

Yes. In addition to Sunnyvale, we work throughout nearby communities such as Mountain View, Santa Clara, Cupertino, Palo Alto, and Los Altos.
