What Happens When Bathroom Fans Discharge into the Attic?

When a bathroom fan falters, discharging moist air into the attic, excess moisture will quickly accumulate. It’s an ideal environment for mould to grow, and it goes unnoticed more often than not. As a preventive measure, a thorough attic inspection can determine if moisture levels are higher than they should be. More than that, when high moisture levels are identified, corrective measures can be taken.

On the downside, if an attic inspection determines that mould has already infiltrated the attic because of bathroom fan discharge, there may be a need for professional attic mould remediation. The fact is, bathroom vents should be vented to the outdoors. It makes sense, and it’s the best way to ensure that excessive amounts of air moisture do not accumulate, however this is not always the case. Some regions actually require this in the building code to avoid the need for attic mould remediation and protect indoor air quality.

One reason NOT to discharge a bathroom vent into the attic is the potential for condensation. When warm, humid air from the bathroom wafts into the attic, condensation can occur, and mould can grow. This situation needs to be rectified by ensuring that all indoor exhaust fans effectively vent to the outdoors. The hassle and expense of remediation can be avoided.

The Role of The Bathroom Exhaust Fan

attic mould remediation servicesA bathroom exhaust fan is a ventilating device that mechanically exhausts indoor air to the outdoors. A ceiling vent fan, for example, exhausts air moisture from the bathroom and prevents the accumulation of warm, humid air. Venting outdoors prevents excess moisture from ending up in the attic cavity.

Conditions That Lead to Attic Mould

Mould problems are essentially moisture problems. So, if there isn’t any moisture, there isn’t any mould. Excessive air moisture in the attic can be caused by a number of factors – improper exhaust coming from the bathroom – blocked or inadequate ventilation – even poor ventilation throughout the attic.

What To Do About Attic Mould Growth 

With any mould infiltration, it's critical to remedy the moisture problem that initially caused the mould problem. An expert attic inspection will identify problem areas, while professional attic mould remediation will ensure that all remnants of mould are removed without any chance of recurrence.

Attic Mould Removal and Upgrades 

Attic mould removal and disposal should be undertaken by a qualified mould technician. This is not a DIY project for a homeowner who has little or no experience. A professional will also advise of any retrofits or upgrades that may be necessary and will recommend options for preventing mould infiltration.

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!
