Patio Door Installation in Vancouver and Lower Mainland

We may not think of it often, but without windows and doors a home or office is just a very large box.

Not only are they essential on a practical level, they also are an integral part of any interior design plan. So it is not a big shock to find out that window and door manufacturers put a great deal of effort into making them both functional and stylish. Unfortunately, that means there are many decisions to be made before you find the doors or windows that are right for you.

Consultation and Installation

While some people seek out professional advice when choosing windows and doors, others are only looking to have them installed perfectly. Authentic Installations is here to help the home and business owners of Vancouver and the Lower Mainland with both.

From front doors that reduce noise to bathroom windows that resist mildew and condensation, we provide a personalized service that promotes long term relationships. Well installed windows or doors can last decades, so it is important that our clients are completely satisfied with their choice. We work quickly and efficiently without rushing or pressuring our clients into choosing their windows or doors.

How Long Does it Take to Install Windows?

This is a question we get fairly often from our clients in Vancouver and the Lower Mainland. As every window installation is different this question can be hard to answer. For instance, very large windows will take longer if the wall has to be reframed to accommodate the difference in size.

However, if we take an example of window replacement where the frames are of a same size, then it is roughly five windows per day. After an in-home consultation we will be able to provide you with an accurate estimate and develop an installation schedule that works for you.

Renovations are Our Specialty

Whether the home and business owners of Vancouver or the surrounding area require a single window replacement, the installation of a patio door, or a complete renovation project, they can count on us.

Our team is big enough to take on large window and door renovations, but small enough to provide personalized service.

Thank you very much for taking the time to visit our website. We invite you to look around to get to know more about both the services we provide and what we strive to be as a company.
