  • Most people build a new house because they want to. We built a new house because we had to. When a fire destroyed our home in June of 2007, we were overwhelmed by the prospect of building. Bay Builders delivered on their promise to build us a beautiful, solid, energy efficient home. The team turned what started out as a stressful burden into a positive and exciting experience we will never forget. We will always be grateful for their compassion, respect, and skill.

  • From the beginning you assisted us in selecting the floor plan that best suited our needs. You even customized the rooms to accommodate our particular needs. Throughout the entire experience time was taken to listen and address any concerns we may have had. The day the house arrived the entire neighborhood took in the show with much interest and enthusiasm. It gave us the opportunity to meet our new neighbours before we actually moved in.

  • Never having built a home before we were quite nervous and confused about the whole process. The Bay Builders team allayed our fears and worked with us every step of the way, providing expert advice and assistance which helped us complete the home worry-free. The first home turned out so well we chose Bay Builders when we decided to build a second home for our son, and we could not be more pleased with the outcome. Thanks to the entire Bay Builders Team!

    George, Elizabeth & Phillip T
  • We are very glad we selected a well built Guildcrest home and that we used Bay Builders as both the dealer and general contractor. Our home is beautiful and gets a lot of compliments from our neighbours and it will be our home for many years.

    Chris & Sue
  • Bay Builders provided us with a tremendous amount for support with all phases of one of the biggest undertakings my wife and I had ever taken on. Their professional assistance in the design phase clearly eliminated the need for any changes during the construction phase, and ensured we received the services and functionality expected of our new home.

Fast, On Time & On Budget

Bay Builders build home across Northern Ontario, our team is  setup to complete jobs in a matter of weeks, instead of months.  Our timelines are easier to manage as we aren’t as affected by weather delays or eronious material ordering processes.  Once, we are at the build-order stage you know where you stand in terms of costs limiting your exposure to cost overruns, making you rest a little easier.

Built Indoors

Would you build a car or a set of cupboards outside? With factory built homes, we are not affected by rain or weather delays, or the all to often building materials sitting outside in the exposed element, which most often leads to trap moisture inside the wall and ceiling cavities. Our factory is fully equipped with the latest technology, tools and equipment to ensure only a top quality product.

Energy Efficient

Any home, built to today’s standard needs to be energy efficient. There is no question that factory built homes can achieve this much easier than stick framed. We offer several energy efficient packages, including R60 in ceilings, to allow you the flexibility of choosing your needs. Our design team is always integrating LEED principles and passive solar design to truly make your home energy efficient. Ask us how are homes are 58% more energy efficient than a stick framed home.
