Why should I consider window and door replacement?

There are many reasons to replace your current windows and doors, even if they seem to be holding up fine. Older windows and doors are less energy-efficient, tend to look dated, or simply don’t match your style. Refreshing your windows and doors can give your house the facelift it needs to keep up with modern design trends, increasing curb appeal and the value of your home. Plus, the energy savings from your new windows and doors will offset the costs involved in installation over time.

How much do custom windows and doors cost?

The good news is, we work with your budget! Because we pride ourselves on having the best windows and doors around, we won’t cut corners when it comes to quality. We’ll talk numbers during our consultation process, taking into account your dream design, the materials available and offering you several options to choose from.

How long does window and door installation take?

While there’s a timeline involved in the consultation, design and ordering process, the installation time is fairly minimal once your new windows and doors arrive. Depending on the number of windows in your home, installation could take as little as a day. Standard windows can be mounted in about a few hours, while doors are a little more involved and can take about 4-6 hours. Speak to us to get a more accurate estimate of your specific window and door installation project.
