What You Need to Know About Cellulose and Mould In Your Attic

Because the attic space is out-of-sight in most homes, mould can often grow and spread on attic insulation in Toronto without being noticed early on. Mould needs favourable conditions to thrive, and attics can often provide the perfect storm. In addition to moisture and darkness, attics are full of insulation, a feeding ground for mould. However, certain insulation products actually prevent mould.

Cellulose blown-in insulation, for example, does not provide a good feeding ground for mould, unlike other insulation materials. If the cellulose gets totally saturated, there may be potential for mould to grow, but typically cellulose insulation is safely treated to prevent mould growth.

Cellulose insulation works well in preventing air moisture from collecting, and that prevents mould from growing. The important thing is if you suspect that mould may be infiltrating your attic, to get a professional attic inspection of your attic insulation in Toronto. At EcoComfort Insulation & Contracting, we handle a full range of safe, affordable, and effective attic services, from blown-in insulation and inspection to mould remediation.

How Does Mould Become a Problem?

Not all mould species will pose a health hazard, but any mould infestation is problematic and should be removed. Mould will grow primarily where there is excessive moisture and poor ventilation. And the attic tends to be the perfect environment. Once infiltrated, the mould will spread slowly and steadily, eating away at potential feeding sources. It means that everything from wood to drywall to insulation is food.

Why Does Mould Grow in Attics? 

Attics are dark, humid and poorly ventilated – three conditions that will allow mould to fester and grow. When the attic is properly air sealed and appropriately vented, there’s little chance that moisture will collect and promote mould growth. When mould does have the opportunity to grow, the attic also provides the necessary food sources, like wooden beams, drywall separations, and certain types of insulation.

Preventing Mould Growth Completely

Preventing mould growth is all about controlling the conditions that lead to mould. A dry, well-ventilated space will not allow mould to grow. And this is where a professional attic inspection can be valuable. At EcoComfort Insulation & Contracting, attic experts assess the roof cavity for air leaks, issues with the insulation, and overall ventilation. Addressing these issues will also address the potential for mould.

Installing Blown-In Cellulose Insulation 

Because some insulation products underperform with regards to mould growth, many installers recommend blown-in cellulose as a good option for the attic. The product has proven itself to provide an effective sealing “envelope” throughout the attic and therefore provides optimum moisture control. Along with air sealing and proper ventilation, the combined “system” works to prevent mould.

Very efficient service from quote to the completion of the job 2 days later. Thanks to EcoComfort, we now have baffles in our two attic spaces as well as insulation that went from extremely poor (builder's quality of 4") to R60. We're extremely happy with the work done and would not hesitate to recommend EcoComfort. Thank you very much!!

From inspection, quote, job, clean up and final inspection of the finished work, Eco Comfort Insulation did a fantastic job. They answered all my questions in detail during the initial consult, and did a great job. They cleaned up properly, and left after I was satisfied. I would highly recommend them to anyone looking to increase their attic insulation. Thank you.

I'm very pleased with EcoComfort. I called them for an attic insulation top up. After the first phone call, someone came to have a quick look at my attic. A few weeks later, two men and their truck came and increased my attic insulation from R21 to R60 with blown-in cellulose. I appreciate that they use Canadian materials (Climatizer Plus). The work only took a few hours and they left everything just as they found it, nice and clean. My house feels a little cozier now with the added insulation. Thanks a lot!

I had a wonderful experience with the Ecocomfort team. I originally hired them to top up my builder-grade insulation from 8 inches all the way up to 24 inches which is approx R-70 and they did a fantastic job. A huge shout-out to the entire team including Arnold, Patrick, Daniel, Louis, Adam, and Paul. Every one of them was friendly, professional and efficient.

Very unusual these days to find a home contractor who in fact lives up to or exceeds their claims and online revues. Wojtek was prompt, courteous, extremely knowledgeable and very patient.........he answered all my questions. Patrick, his brother and his two colleagues arrived on time, were careful and tidy, did an excellent job and cleaned up beautifully. I was skeptical of the purported benefits of adding attic insulation but during this recent late summer heat wave I have not required air conditioning during the day and only a bit overnight. Aside from potential future energy savings, the benefits were immediately evident. I would highly recommend Ecocomfort to anyone considering anything they do.

For 800 sq ft attics - EcoComfort Insulation price was HALF what 2 other insulation contractors quoted me. Very professional starting from the quote (Wojtek) - who explained the process, to the guys who did installation, very efficient and professional, - vacuumed and cleaned afterwards - can't wait to see how it retains the heat on these colder evenings. Highly recommend them.

Tom and co. were amazing!! They just completed the job within 3hrs and I had zero insulation to begin with so it was a big job. They were truly professional, cleaned up after the job and walked me through the inspection. Ontop of that, they also helped fix a small leak in the roof which they noticed during the job!! That's service beyond and above and truly appreciated!! Looking forward now to having warmth in the bedrooms this coming winter and would definitely recommend EcoComfort to anyone! You guys are awesome...

We had a great experience with EcoComfort. Arnold attended our home to provide us with a quote, and he explained the whole process and answered any questions we had. The insulation itself went well- two workers came to do the job. They cleaned up afterwards. We already notice a difference with our second floor feeling less hot in the summer heat now that we have our attic insulation done!

I hired EcoComfort Insulation after researching the more labour-intensive option to replace the batting by hand. It was like a mountain range of pink batts in the attic which was honestly a bit terrifying. Patrick sent a crew with a truck which sucked the old, dusty, pink stuff out and blew in new R60+ cellulose. I am so happy I went with this installation method and it was well worth spending the extra money.

I had Eco Comfort in recently to blow in new insulation after we had recently taken down and installed a new ceiling. Everything went very well. Everything from getting the quote, scheduling the work, and the team coming out went very smoothly. Everyone was very friendly and the crew did a great job. I would definitely recommend them to anyone.

The guys did a spectacular job in removing the old insulation and replacing it with cellulose. They were friendly, efficient and professional. They also installed a bathroom roof vent for better air circulation AND installed weatherstripping for our attic hatch. After work was done, they cleaned up the minimal dust that occurred and left our place as if they were never there. This company provides awesome service. Hire them!
