Hiring a home addition contractor

A home addition isn’t like simply renovating a bathroom or kitchen. You’ll need the help of highly qualified experts. That’s why hiring a home addition contractor from the get-go is ideal. Of course, this will need to be done only after getting your permit from the city.

Home addition contractors are basically general contractors that specialize in home additions. They’ll be able to see what kind of work can be done with your home, and how to go about this extension. Vertical extensions are rather different from horizontal extensions. If you build upwards, the structural work won’t be the same as simply extending your living room – for instance.

They’ll take into account your needs and desires to better serve you as well. Our home addition experts will ensure that the process of extending your home runs smoothly.

Your Personal Assistant

Questions to ask a home addition contractor

When meeting with the contractors our Renovation Advisors refer your way, you’re better off having some questions prepared. Being able to see what they can offer you and how they respond to your questions will give you a better sense of the way they work. You’ll also notice which contractors you build a better rapport with during the process. It’s usually best to go with your gut feeling when picking the contractor that’ll work on your home addition. However, hearing the answers they offer up to your questions will confirm your decision. If you’re unsure about what to ask them, take a look at the following questions.


10 questions to ask home addition contractors

  • How long will the renovation work take?
  • Who will my main contact be during the renovations and who will be supervising the work being done?
  • How many subcontractors/employees will be involved in the process?
  • What’s included in the quote you’ll be providing me?
  • Will we need to prepare the construction site ahead of time or will your team be doing that?

What a home addition contractor 
can assist you with

Bump out addition

A bump out addition is a typically much smaller addition to your home. It’s essentially adding more space to existing rooms. Of course, depending on how big you want your new kitchen or living room to be, it might turn out as big as adding a new room to your home. It creates more living space for you and your family to live comfortably.

Sunroom additions

Adding a sunroom to your home adds general living space to your home. Depending on whether you plan on using this room all year-round, there are different options available. You can opt for a four-season sunroom, a three-season one, a solarium or a simple screened porch. If you choose to get one that is habitable all year-round, it’ll require a lot more work, such as plumbing and electrical, hvac, and more – as opposed to a simple screened porch. Of course, sunroom costs vary accordingly.

Second storey addition

Maybe you live in a bungalow and are looking to convert it into a two-storey home. Home addition contractors can certainly work with you to get a second storey put in place. They’ll take into account your home’s structural integrity (with the help of an architect and/or engineer) and see what can be done to turn this project into reality.

Garage additions

Maybe it isn’t so much living space you’re looking for, but rather a place to store your tools, your outdoor activity sets and your car. Getting a garage addition done is also feasible. Depending on where you live, different rules and regulations apply according to your garage’s insulation and other elements. If you simply want a shelter for your car, you can also opt for a carport. Your garage’s cost will vary accordingly as well.

Additional room over the garage

If you’re looking for additional living space and a garage, you can always get a garage built with a room above it.

How much does a home 
addition contractor cost?

This all depends on their level of expertise and and the type of addition you’re planning on getting done. The work home addition contractors complete can start anywhere around $180/sq.ft. to over $215/sq.ft. Your home addition cost will essentially vary depending on its complexity, including what kind of foundation it’s on, it’s materials, and much more.
