    Signs to Watch For

    A few tell-tale signs that your house needs to have its insulation replaced or upgraded, whether through injection or spray-foam application.

    Higher utility bills. If HVAC costs are spiraling upward in your energy bill, it might be a sign that your insulation is no longer helping to keep your home warm or cold enough.

    Hard-to-control home temperatures. If managing your thermostat settings for ideal home temperature is getting to be a constant problem, poor insulation may be the culprit.

    Vast temperature differences from room to room. If one bedroom in your home is drastically warmer or colder than another bedroom, or other similar living spaces are wildly different in temperature, your insulation may need to be serviced.

    Benefits of Insulation Injections

    Lower utility bills. Injected insulation makes it easier to control a home’s temperature with less energy, which results in lower utility bills.

    More comfortable temperatures. By preventing air leakage through small gaps, injected insulation keeps home temperatures warmer in winter and cooler in summer.

    Reduces carbon footprint. Insulation doesn’t require outside energy sources to work, which means it has no detrimental effects on the environment.

    Easy installation. Injected insulation is applied through sparse, discreet holes drilled into the wall that are easily patched up and cleaned once the installation is over. There’s far less mess or cleanup than with other options.

    Cost-effective. Foam insulation is less expensive and frequently more effective than fiberglass insulation. The injection method is usually significantly less than spray foam.

    Long-lasting. When properly installed, foam insulation can last for as long as most families are likely to live in their home — usually at least 30 years, but potentially 50 or even longer.

    Insulation Injection vs Spray Foam Insulation

    For the most part, injection and spray foam insulation use the same base material. They both apply insulation that serves as an air sealant to make your home’s air more comfortable and clean.

    There are differences in how the insulating foam is applied. For insulation injection, less prep work is involved. Crews simply drill a few holes in walls, inject the insulation with special tools, then close and clean them up.

    With the somewhat more invasive spray foam, crews must remove any old traces of fiberglass and cellulose before applying the insulation. They must also move any furnishings and belongings around and cover them in plastic.

    Injected insulation foam doesn’t expand the way that spray foam does. Therefore, it can fill any nooks and crannies between the walls that spray foam might not get to. Also, injected insulation foam doesn’t release chemical substances in a process known as “off-gassing.” Some spray foams may result in a negligible amount of off-gassing.

    We live in an older home near a large park area. Since buying our home, we’ve had to deal with the occasional rat. These guys came out and sealed my entire attic space – vs setting a few traps. Then vacuumed out the entire space that had nearly 100 years of debris – including from our new roof and insulated the entire house. Love the 5 year warranty against the rats and we already notice how much warmer the house is. The did a great job keeping area clean and protecting floors, walls while working. Highly recommend.


    It’s a stressful situation when you find black mold in your home. The guys at Attic Projects were professional, polite and respectfully clean. They finished the job in a timely manner and went the extra mile to make sure I was satisfied with their work. Once the job was completed we instantly noticed a difference in our home’s humidity- going from 70% to the optimal 50%. I’d highly recommend these guys. Jordan, your customer service was top notch, thank you for making this a stress free experience.


    Attic Projects was so incredibly thorough and detailed with their description of how and why they were going to do each step, I knew I could trust them. These guys get it!! Total professionals, hard workers and they invited me to poke my head up in the attic during and after the job was complete. My in-laws received before and after pics and received a 5-year warranty on rodent proofing This was a big job and these guys absolutely killed it. I’d recommend them to anyone with similar issues. Thanks Attic Projects!!

    Frequently Asked Questions:

    How do I know if I need new insulation?

    Signs you need new insulation may include higher utility bills and that the temperature is difficult to control within your home. Also, if you have some rooms that get cold while other rooms get hot, you may have an issue with your current insulation. If you are experiencing any of these signs, you may have old or damaged insulation and should call Attic Projects to conduct a free inspection.

    What is insulation injection? Why would I want this instead of spray foam insulation?

    Insulation injection allows us to insert insulation in all the nooks and crannies between the walls that spray foam may not be able to fill. We recommend insulation injections over spray foam because it fills more space and doesn’t release the chemicals known as off-gassing” that you get with spray foam.

    Why would I want to replace old insulation with insulation injection?

    Getting rid of damaged or old insulation and replacing it with insulation injection will help lower your utility costs, keep the temperature in your home comfortable, reduce your carbon footprint, and the insulation is made to last for years down the road.

    Should I hire a professional to install my new insulation?

    Yes! Instead of installing the insulation yourself, you should hire the professionals at Attic Projects to install it for you. When you hire us, we will come out and conduct a full free inspection to ensure you are getting the right insulation and that no other issues are going on in your attic or crawl space.

At Attic Projects, we not only humanely remove the rodents and pests from your home, but we also rodent-proof your home so they can’t come back. In order to keep the pests and rodents out permanently, you have to close up every entry point that they may squeeze into. Call Attic Projects today to get your free estimate.
