    WHY CHOOSE US Our company has provided home insulation, soundproofing, and air sealing services for over a decade. As the first choice for new home builds and renovations, we are dedicated to excellence, efficiency, and quality. Our business policy is transparent, and there are no hidden fees. We confidently claim that our business model is far better than the rest. Quality is our top priority for every project, whether small or large, and we are proud of our reputation and customer satisfaction. Every project is built to the same high standards and consistent quality with our professional crew. What sets Warm Cozy Cozy apart as your insulation contractor? As a trusted source for home insulation, Warm Cozy Cozy can inform you about the best materials for each area of your home, saving you money and energy. Insulation is often misused, or steps are overlooked when installing it. In order to provide our customers with the best solutions on the market, we ensure our staff stays current with the latest learning and training provided by industry suppliers and associations. OUR SERVICES Attic Insulation Cellulose insulation is composed from treated wood- or paper-based product. It is mechanically spray blown into open spaces of the house or commercial building to slow down the transmission of heat or cold. Home Insulation All year round, insulation maintains a comfortable temperature in our homes, keeping them safe from the cold of winter and the heat of summer. When a house is insulated correctly, it requires very little additional heating and is very energy efficient. Soundproofing Just as a building can be insulated for heat, it can also be insulated for sound because it is an excellent way to minimize noise pollution. A complete soundproofing system includes floors, ceilings, and walls for optimal acoustic comfort. Thermal Home Inspection Insulation is a thermal transmitter blocker of heat or cold, preventing thermal energy from passing through. That is why we offer thermal imaging home inspections to see precisely where your home is losing heat. No more guessing games; know your home's specific needs. At Warm Cozy Cozy, we provide insulation removal in certain circumstances. We will provide this service if the following apply: - When there is a leaky roof, mould will grow. - Water-damaged insulation will no longer insulate your home. - Animal infestation leads to unsanitary insulation caused by urine and feces. - Wires chewed by the animals pose a fire hazard. - Old insulation no longer insulates your home as it has a lifespan. - When your old insulation is dirty and causing a bad smell in your home. https://inaudible.co
