Attic Insulation Company in Fremont, CA: Blown-In, Batt & More
Warranty, Best Turnaround Times, and Estimates on the Spot
A lot of homes in Fremont still have attic insulation that’s well past its useful lifespan. That could mean fiberglass batts from the 1980s, insulation flattened by foot traffic or rodents, or material that was never installed correctly in the first place. At EM Energy & Air, we specialize in removing what no longer works and replacing it with clean, high-performance insulation that helps your entire home feel more comfortable.
We’re known for fast turnaround times, reasonable pricing, and a no-pressure approach. Our inspections are always free, and we give estimates right away. Every insulation job we do is backed by our unlimited labor warranty. We also offer financing at no cost to the homeowner.
If your upstairs rooms are too hot in the summer or your energy bills keep climbing, it might be time to take a look at the attic. Most homes we inspect in Fremont need either an upgrade or a full replacement.

Anthony and Judy Price
I highly recommend EM Energy & Air!! We had them remove and replace our attic insulation, clean and sanitize our attic and install new insulation and a heat shield in our home. The crew was awesome. They laid down plastic for the pathway, and around the entire area where work was to be performed. It took about 5 hours and they were non-stop working to completion. We got a few quotes and were well worth our cost. Can’t say enough good things about the entire process, from initial meeting, quote to work completed!!

As a Professional Engineer and HVAC business owner, I can certainly recommend E&M. I pursued multiple bids and Eilon was by far the most knowledgeable, thorough and professional. His field team was courteous, worked neatly, and finished the project on time. We already notice that the HVAC system runs less and the house holds temperature better. Strong endorsement from me.

we are very pleased having hired EM Energy & Air trough Eilon to tackle our attic project. From scheduling an appointment to getting the job done all went smoothly and faster than we expected. After reaching out on Sunday our attic got renovated within 1 week time frame: removing the old insulation, clean up of the attic, installing a whole house fan, redoing the HVAC pipes and insulation. I am very pleased with work done and professionalism of the crew. They worked very clean and swiftly ( all work was done in 1 day).

I recently hired EM Air & Energy to clean up and re-insulate my attic and handle some heating work at my home. I’m thrilled with the results and highly satisfied with their service! Elion visited my home to assess the attic and heating setup. He was thorough, knowledgeable, and gave me valuable suggestions tailored to my needs. The contractors who came to do the actual work were efficient, hardworking, and professional throughout. The pricing was fair, and I truly feel I received excellent value for the cost. The entire process was seamless, and I’m happy to recommend EM Air & Energy to anyone looking for top-quality service.

I called up these folks initially to get an estimate to clean out my attic. They provided me the best bid I received in terms of details and price. After a candid conversation with Eilon, I decided to have EM energy and air also install new insulation and seal off my attic. The crew were very thorough in sealing off all the possible rodent entry points and did a great job with the cleaning. And the insulation came just in time for the heat wave. It made a 10 degree difference in the inside temperature of my home. Great experience, would highly recommend them.

Installing two heat pump with EM was a breeze; communication was very timely and the job was done well and as agreed. Quote process: They got me a fair quote same-day by just from sending them info over text (while other companies took weeks) and the price was fair. Change orders: I decided later I want two units, and again it was a smooth process. Also later there was an equipment change – and it made it convenient for me. Job Day: 4 guys arrived as agreed and get it done same day. I talked to most of them and all were polite, nice and upbeat. They let me inspect the work closely, made sure I am happy and give me tips on next steps. TLDR; Would hire them again and I am happy to recommend to my neighbors!

Does Your Attic Insulation Need Replacing?
Compacted or Sagging Material
Insulation only works when it maintains its shape and coverage. Over time, gravity compresses older materials, leaving gaps where heat escapes or enters. You may not notice it until temperatures spike or drop, but the effects show up on your utility bill.
Rodents and Contamination
It’s common for attics in Fremont to show signs of rodent activity. Mice and rats burrow into insulation, tear it apart, and leave behind waste. This doesn’t just ruin the material. It creates serious air quality concerns for the entire home.
Moisture from Roof Leaks
Even a slow drip from the roof can soak insulation and lead to mold growth. Wet insulation loses its R-value and holds onto musty odors. In these cases, it’s best to remove the damaged material and seal the attic before installing anything new.
Age and Poor Installation
Many homes in Fremont were built before energy codes improved. That means the original insulation may have been minimal to begin with. Even if additional layers were added later, they may not have been sealed or installed correctly.
How Bad Insulation Affects Your Home
Higher Energy Bills
Poor attic insulation lets heat pass freely in and out of the home. Your HVAC system runs longer, which drives up monthly costs and puts strain on your equipment.
Inconsistent Indoor Temperatures
If your home has hot spots upstairs or rooms that stay chilly no matter how high the heat is set, the attic could be the issue. Gaps in insulation allow for uneven airflow and poor temperature control.
Dust and Allergens in the Air
Old or contaminated insulation can circulate particles throughout the home. You might notice more dust, a lingering smell, or worsening allergy symptoms.

Comprehensive Attic Insulation Services
Blown-In Fiberglass
Ideal for filling tight spaces and boosting coverage in hard-to-reach areas. This is a popular choice for topping off existing insulation.
Fiberglass Batts
Works well in open attic spaces with standard framing. Batts are easy to install and hold up well over time.
Cellulose
Made from recycled paper and treated for fire resistance. This dense material blocks airflow and helps keep the attic sealed.
Mineral Wool
Heavier than fiberglass and more resistant to fire. It’s a good option for homeowners looking to reduce outside noise as well.
We’ll help you decide which material fits your home best. If your attic already has some insulation, we’ll test its condition and let you know whether it can be kept, supplemented, or needs full removal.
The Attic Insulation Process
Free Inspection and On-the-Spot Quote
We begin every job with a detailed attic inspection. Our technician checks for gaps, compaction, signs of rodents, and moisture issues. You’ll receive a clear quote the same day.
Removal of Old Insulation (If Needed)
If existing insulation is no longer functional or if it’s been contaminated, we remove it completely and dispose of it safely.
Air Sealing
Before installing new insulation, we seal joints, fixtures, and attic floor gaps to stop uncontrolled air exchange. This improves comfort and reduces dust and energy loss.
Installation of New Insulation
We install the selected material to proper depth and coverage, taking care not to block vents or airflow. The job usually takes one day.
Final Walkthrough
Before we leave, we walk the project with you and answer any questions. We’ll also check attic ventilation and make recommendations if airflow needs improvement.
Other Attic Services We Offer
Radiant Barrier Installation
Adding a radiant barrier helps reflect heat out of the attic, especially useful during Fremont’s hotter months. It can be installed over new insulation for maximum efficiency.
Ventilation Improvements
We install ridge vents, soffit vents, and attic fans to promote airflow and prevent heat buildup.
Ductwork Sealing and Inspection
Leaky ducts in the attic waste energy and reduce system performance. We inspect ductwork and offer sealing or replacement if needed.
