    Thermal insulation: Interior insulation; 500 - 1000 sq ft

    Anthony, Courtney and the team did an amazing job and delivered exactly what we asked for and made sure our project was done on time, even after the scope of the project got bigger while work was already started. We are really happy with the end result and can feel our floor is warmer after the garage ceiling was insulated. Very professional and organized. We highly recommend their team if you need to get your home insulated!

    Thanks so much Peter & Vanora for taking time out your day to share!!! And no worries, often times clients may change their minds during the course of their renovation, and one of our attributes are that we are able to adapt on the fly fairly quickly, as was the case in this instance. It was a pleasure working with you on your home and we would love to do so again if need be, all the best!!!

    Attic Insulation

    From my first contact with Anthony to the departure of Courtney and her team when the job was completed, this company provided exactly the service I had requested. Anthony answered all my questions and never rushed me into making my decision. The work crew arrived on time and kept me informed every step of the way about what to expect over the three days it took to complete the job. They took care to cover floors and other surfaces and did a great job vacuuming before they left. I could not have asked for more - thanks for a job well done!

    Answer from pro:

    Much appreciated!!! We really do try our best to make the often hectic and stressful construction process as easy and seamless for our clients as possible, thank you for the attesting to that!!! Every home is our own, and yours was no different, it was a pleasure and we hope your new attic insulation performs as it should as the temperatures dip below zero, all the best!!!

    Attic insulation update

    We were most impressed with the work done by Exotherm on our attic insulation update. From the initial meeting with Anthony to the clean up and install done by Courtney and her team, the people from Exotherm showed that we were in good hands. They communicated what was happening at each stage, took obvious care to ensure that the work was done properly, and consistently made us feel that our home was in good hands. We were most satisfied by their efforts and we highly recommend the Exotherm company.

    Thank you so much Greg and Maura for inviting us into your lovely home, and for trusting the full remediation of your attic to our team!!! Unfortunately the attic is arguably the most neglected area of the home when it comes to insulation, although it is one of the only places where the state of the insulation is visible, most have never even been up there to inspect it!!! Even when it is inspected by auditors, inspectors, contractors and homeowners alike, their lack of knowledge in regards to the building envelope makes most believe that a simple top-up is the solution, and sometimes it is, but many homes, especially the older residences that were built prior to the advancement of building science, have very old insulation that has lost its R-value, non-existent vapor barriers, uninsulated ductwork, exposed attic walls etc., all of which can lead to excessive heat loss, and serious issues such as mold. We pride ourselves on providing full assessments of the attic, and also advising on solutions to these problems, as well as doing our best to avoid potential issues in the near or distant future, as we offer a plethora of insulation applications which all can perform well given the right circumstances. The insulation in ones home is truly a "system", and all components need to work together as best they can, we are glad you chose to trust our proposal for yours, and feel confident that your attic will keep your home at the temperature you would like it to be at for years to come, all the best!!!

    Spray foam, Drywall, Mud

    Being a General Contractor for quite some time, I finally decided to take a leap and invest in building a custom home. As many in construction may know, securing a project of that magnitude without a portfolio is difficult, with the countless options available to the consumer. Really the only way to get into the game is by doing it yourself, so I found an older property on the Hamilton mountain that was decently priced and got to work. This being my "show" house, I wanted to enlist the best trades to aide in a stellar finished product in a timely manner as I was doing this with bank money accruing interest. I had seen Exotherm's trucks around the GTA, looked them up online and sent them a request on their website. From the initial call, to site visit, quote and ultimately the work performed, Exotherm exuded the utmost professionalism and passion for what they do, making me feel like my project was the only one that mattered. They applied spray foam to all exterior walls throughout, exposed ceilings/floors, rim joists and the perimeter of the attic, applied intumescent coating to the foam in the basement cold room which was being left exposed, installed sound attenuation batts in the basement ceiling and installed cellulose in the attic. They also handled the drywall installation, resilient channel and drywall finishing, all of which was done seamlessly and to a very high standard of quality, with constant communication and updates throughout, my other trades as well as the inspector even commented on how well the work was done. I couldn't imagine having used anybody else and although they were by far the most expensive quote I got, I feel it was well worth the money spent, thanks Exotherm!!!

    Answer from pro:

    Wow!!! Words can not even come close to expressing our gratitude for your glowing acknowledgment of the passion, care and commitment to quality we aim to deliver day in and day out. We are honored to have been able to lend all of the various services you entrusted us with in constructing your first full custom home project!!! There are countless others that you could've enlisted, and your recognition of our dedication to becoming know as the GTA and Southern Onatrios premiere custom home insulation/drywall contractor is flattering to say the least. The house turned out beautiful as I was lucky enough to be able to pass by and see the final product!!! Good luck in all of your future endeavors, hopefully this is the first of many, and we would love to work with you again!!!

    Attic Insulation

    From start to finish, Exotherm did a phenomenal job retrofitting our attic. Their professional service from the quote to the final clean up was amazing. I would definitely recommend them to anyone looking for top notch work. They truly have it "down to a science." Thank you again Anothony, Courtney and the rest of the team.

    Answer from pro:

    We appreciate the kind sentiments, as well as the chance to assist in the remediation of your attic!!! At Exotherm, we truly do try our best to make the process as smooth as possible for our clients, especially with projects that require multiple days of work and intrusion into ones home. Thank you for acknowledging that, it was our pleasure and we would love to work with you again in the future!!!

    Professional and efficient

    Delivered two phases of our project ahead of schedule. Professional and efficient. Well organized with work and documentation. Recommended to me by a friend, and I would do the same.

    Answer from pro:

    Hi Daniel, Thank you for the positive attestation, as well as for trusting us with multiple phases of your project. Although we do service the entire GTA and Southern Ontario, we also acknowledge that it is quite some distance for us and local trades would understandably be cheaper than we would be, so we appreciate the opportunity that much more. Keep us posted on the next phase of the project for the drywall installation and finishing!!!
