Hello, yes, we have assisted many customers in applying for government energy efficiency subsidies. We are a certified Energy Star doors and windows manufacturer, and our products can help your home meet government energy efficiency standards, making you eligible for up to $20,000 in rebates. The program is called the Greener Homes Grant. For detailed procedures and application methods, please visit our website: https://transitionenergetique.gouv.qc.ca/en/residential/programs/renoclimat.
Hello, yes, we are an established company with 16 years of experience in the production and installation of doors and windows. All our products are manufactured locally in Quebec, using high-quality materials that meet Quebec standards. This ensures that our doors and windows can last for 20 years or even longer.
Hello, the standard ER Rating is 34. We can produce doors and windows with ER Ratings of 34, 35, 36, and even higher. However, based on our many years of experience, an ER Rating of 34 meets the needs of most customers. The cost of producing doors and windows with a higher ER Rating is significantly greater than the potential energy savings you might achieve. Therefore, unless you have specific requirements, ER Rating 34 is a reliable choice for both residential and commercial doors and windows.
Hello, we do not accept standalone repair orders for doors and windows. If you are replacing some doors and windows and the remaining ones are damaged, we can assist with repairs in such cases. However, we do not provide a quality guarantee for the repaired doors and windows.
Sorry, we only produce entry doors and patio doors. We do not manufacture or install interior doors or garage doors.
Hello, we can produce various doors and windows suitable for sunrooms, including three-season and four-season sunrooms. However, please note that we only manufacture windows for the side walls of sunrooms and do not produce windows for the roof of sunrooms.
All our windows are custom-made to fit your house after precise measurements are taken on-site. The door sizes are fixed; however, most entry doors in homes are standard sizes, and our products are designed to fit these dimensions. Please rest assured that our sizes will generally cover your needs.
Hello, yes, we do. We have partnered with FinanceIt to provide our customers with convenient and quick installment payment options when purchasing doors and windows from us. Additionally, customers who purchase our doors and windows may also be eligible for a government interest-free loan of up to $40,000. Please visit our website for more details.
