The Victorian and Art Deco buildings of Old Pasadena, and the various museums and historic sites scattered in and around the city of Pasadena, CA, are not the only old buildings in town. Pasadena has plenty of older homes and structures that residents love for their antique feel and decor.

And yet, practical matters like energy efficiency, attic insulation, proper home ventilation, and keeping out rodents and pests must also be taken into consideration. Without a fully insulated attic, crawlspace, and walls, you are throwing money away, living in less than ideal comfort, and doing less than your part to protect the environment.

Pure Eco Home Services


As a trusted and experienced insulation contractor, Pure Eco offers residents of Pasadena, California, fast, effective, and affordable insulation installation solutions to optimize their home's energy efficiency. We also offer many other attic insulation services that serve to enhance your building and upgrade its resale value.

Our services can transform old or under-protected homes into examples of maximized energy efficiency and eco-responsibility.

Here are some of the main services we provide:

1. Air Sealing

Air sealing is the necessary prep work that must precede the installation of insulation. If your attic is un-insulated or under-insulated, it is undoubtedly the path through which the bulk of your home's heat is escaping in the winter. It is also the entry point of much unwanted heat during the hot summer months.

All air leaks must be located and sealed to ensure that new insulation does not badly under-perform. Our expert staff at Pure Eco has deep experience in locating air-leakage points. We know where to check: under dusty or sunken batts, around vents and chimneys, and near the attic access hatch are prime "suspect areas."

We also can use a blower door, a fog machine, or a simple flashlight to help locate even the smallest air-leak points.

Caulk or other sealants will be used to eliminate small holes and cracks. Weatherstripping around the access hatch is also key. Large gaps or areas over false ceilings need to be covered with OSB board, plywood, or drywall. Polyisocyanurate foil may be best in some locations, and metal sheeting plus high-heat-grade caulk must be used around chimneys.

Normally, it's best to remove unused chimneys because they create an efficiency-killing "thermal bridge" that will siphon the heat right out of your house. But at least the upper portion should be taken down and the uppermost opening sealed off.

Finally, we will also check along the top plate to see if the drywall installer sealed it off to prevent leakage. If not, we will seal it ourselves.

2. Installing Insulation

In some cases, you may wish to remove old, inefficient insulation. Or, if you have asbestos-containing vermiculite insulation in your attic, we can safely remove it before re-insulating. But first-time insulation jobs are most common.

After we have fully prepared your attic or other space by air-sealing, we will install the insulation of your choice in full accord with all manufacturer's recommendations. We know how to get the highest possible performance level out of new insulation by installing it free of gaps or weak points that could threaten the effectiveness of the whole "insulation shield."

While there are many specific insulation options, we can summarize the main options into three main types:

Batts Insulation


Batts, those long sections of rolled-out insulation with paper backing, are popular because they are among the most affordable type of insulation available.

Batts are generally made of either fiberglass or cotton. Both materials work about as well, but cotton batts score high points environmentally since they are made out of recycled blue jeans.

The main drawback of batts insulation is that it leaves a certain amount of unfilled, or not tightly filled at least, space due to its design. By properly installation and joining the pieces at the joints, adequate results can be obtained for many situations, but admittedly, other forms of insulation could push energy efficiency to higher levels.

Whether or not batts should be your insulation of choice or at least one of multiple types used will vary. We can help you weigh the costs and cost-savings to make the choice that best fits your needs and your budget.

Blown Insulation

Blown-in insulation can fill in space on your attic floor (or elsewhere) more compactly than can batts. We have a fleet of trucks and blowers and run a hose to any location in your house.

Blown insulation is typically made of either fiberglass or cellulose. Again, both types work about equally as well at the job of insulating. But cellulose is made of recycled newspapers (a plus for the environment), while fiberglass insulation is sourced from sand (an abundant natural resource.)

At Pure Eco, we can install your blown insulation quickly, without making a mess, and ensure it evenly and fully covers the desired space.

3. Radiant Barriers

A radiant barrier can add yet further insulating power to your attic, on top of air-sealing, insulation, and ventilation improvements.

A radiant barrier will install directly below the underside of your roof line. It will keep excess heat from ever getting into your attic by reflecting back and away radiant heat from the sun that shoots through your roofing.

If you have ever used a radiant-heat heater, you understand how this form of heat reaches objects directly rather than first having to be conducted through solids or convected through gases. That's a benefit when a heater can keep you warm on a cold day, but the last thing you want during the hot Pasadena summer is radiant heat pouring into your attic, making your uncomfortable and raising your cooling bill.

Radiant heat barriers typically use an aluminum reflective surface. They may have numerous layers to maximize the results.

Proper installation of radiant barriers is crucial because poor installation can allow dust build-up over the years, which diminished the reflective power of the barrier's surface.

At Pure Eco, we are familiar with the various radiant barriers on the market today. We can help you choose the one that's right for you and install it for optimal performance.

4. Rodent-proofing Your Attic and Roof

Another service we offer a Pure Eco is that of rodent-proofing. Rodents like mice, rats, and squirrels may be taking up residence in your attic (and from there, making their way to other parts of your home.)

We can "rodent proof" your attic to keep rodents and other pests from getting in. We can also set up traps to catch the animals that may already have gotten into your attic.

Rodent proofing is largely analogous to air-sealing. We look for all openings and seal them off. We may need to use stronger barriers at points, however, to keep animals willing to use teeth and claws to break into your home from doing so.

Rodent proofing also involves fixing any weak points or gaps in your roof. And installing vent covers and chimney caps is also recommended. Finally, cutting back branches that lean over your roof and invite rodents to walk on top of it is another important step.

I already had my main attic done last year by a different company that did not do what they said they would and ended up damaging my ceiling. Decided to go with a different company this time around for a smaller attic of an addition that isn’t directly connected to the main attic.

The attic had no insulation at all (built in the 1930s). It needed debris vacuumed out, rodent proofing, and R-38 batt insulation.

After getting quotes from several folks, decided to go with Pure Eco. Quick turnaround, reasonably priced, good professional crew lead by Martin, and clear communication through my assigned contact Jasmine. Discussion and quote was based on photos I took. Contract and payment was handled all through e-doc services. And they made sure to give me an overview of the work done before leaving. The difference in temperature was a noticeable improvement that night.

Highly recommend.

Our home needed some serious insulation and duct work done. It was awful and quite old (the insulation shrunk to approximately 3″). We called three companies for a quote, and we only saw two. We decided to go with them, before seeing the third, because of the amazing deal they offered and because they would be able to do it immediately. Ben was our sales guy and he was more than helpful and extremely knowledgeable. He made sure to inform us that they are licensed, bonded, and have workers’ compensation insurance, which kept me at ease.

The following day was the installation. Ben told us that they would be there from 8AM – 7PM (latest). They arrived on time, and completed the job by 3PM!!! I was shocked and thoroughly pleased. William, the supervisor of our job, was extremely friendly, and his crew was very professional. They cleaned up their mess; it looked as clean as when they arrived.

I highly recommend them and think that anyone that uses them will do so as well. Hi

I am a firm believer in referrals from friends when it comes to anything for my home and this company was a good referral for sure. My husband and I love Pure Eco and would definitely recommend them to everyone.

They have very professional installers and managers. Everything went smoothly from the scheduling to the end of the job. They use new machines and trucks (I tend to judge a book by it’s cover, unfortunately).

We had them replace our duct system and they installed Radiant barrier. They came in and did their job and left with no mess behind. Definitely give them a try!

We recently bought a house in Canyon Country and the garage was completely exposed and got extremely hot this time of year. When it was 90 degrees outside, the garage was well over 100 degrees. I got quotes from about a half dozen companies but was the most impressed with Pure Eco, especially their representative Sara. She was very helpful and she worked with me on the quote and gave me a lot of of great suggestions as to the best way to get our garage as cool as possible while staying within our limited budget. She recommended insulating the ceiling and front gable and then putting in radiant barrier. Her team came out and did the job in one afternoon and cleaned up afterwards. And now our garage is a LOT cooler. I can definitely recommend Pure Eco.
