My attic had frost and condensation problems. Wojtek from Ecocomfort came by and explained to me that this was due to a lack of insulation and inadequate ventilation in the attic, along with my bathroom fans being improperly vented. He explained very clearly what the step by step procedure would be to fix this issue.
The crew was very punctual and polite, they installed additional soffit vents, 2 roof turbines, 2 bathroom roof vents, and insulated my attic to R50.
I've been peeking into my attic since the job has been done, and there's no signs of condensation anymore. My house is noticeably warmer as well.
I'm extremely satisfied with their work and professionalism and would not hesitate to recommend them.
