When to hire a basement contractor

Basement contractors are essentially general contractors that specialize in all that is basement reno. You'll need their help if you plan on converting your space into an income property, a new space for your family to enjoy, or even to finish your unfinished basement. By taking a look at your space, and taking into account your needs & desires, they'll be able to understand what needs to get done. They'll also be able to assess which subcontractors will be needed for the project. Basement contractors will use their expertise to ensure your basement renovations run smoothly.

Questions you should ask a basement contractor

It's important to meet with potential basement contractors before beginning any work. When meeting with them, you'll get a sense - through your discussions - of whether or not they're the right contractor for your basement remodel. Be sure to ask them any questions that pop into your head regarding the work that is to be done. The more thorough you are with your questions, the better. Plus, you'll notice when discussing with potential contractors that you have better rapport with one than with another. Go with your gut feeling - so long as they're able to properly answer the questions you ask them. If you're unsure about what to ask them, take a look at the following questions. 

10 questions to ask a basement contractor

Here are some questions you should be asking basement contractors you might hire:  

  1. How long will the renovation work take?
  2. How many subcontractors/employees will be involved in the process?
  3. Who will my main contact be during the renovations?
  4. Who will be supervising the work getting done?
  5. Will we need to prepare the construction site ahead of time or will your team be doing that?
  6. Is debris disposal included in your quote?
  7. What precautions will you take to avoid any damages to my home?
  8. Is it possible to see some of your past work? Or obtain client references?
  9. What is the payment schedule?
  10. How long have you been in business with this business name & license number (if applicable)?

At RenoAssistance, we've already audited every contractor we do business with, so you won't necessarily need to ask them too many in depth questions. Though, being vigilant never hurt! Feel free to ask them any questions about their judicial background, their liability insurance, etc. 

What kind of technical work does a basement contractor do?

You'd be surprised of the scope of work a basement contractor can do. They can certainly convert your space into almost anything you'd like, but there might be preliminary work that'll need to be done! Here's some technical work they're qualified to do: 

Basement waterproofing

Waterproofing, dehumidifying, and more. A basement contractor will know exactly what to do to prepare your basement before proceeding to finishing it. They'll be able to install a waterproofing system, a vapor barrier, install a reliable sump dump system, dehumidify the space, and more. Ensuring your basement's protection before moving forward with any other basement renovations is ideal. 

Crawl space decontamination

A crawlspace is still technically a basement! Not all homes have a crawlspace, but if yours does, it must be properly taken care of because, if issues arise, they'll most likely be nightmarish. It's mold's favourite hiding spot because of the high levels of humidity that can be found there. Of course, this can be quite damaging to the home. To avoid any issues and maintain a healthy crawlspace, there are a few things that need to be taken care of. Firstly, proper waterproofing is a must. It'll avoid any water infiltration. A vapour barrier should then be installed to limit humidity from spreading from the ground up. It is also recommended to keep this part of your home heated between 12°C and 15°C all year long. This will avoid any extreme temperature fluctuations that might invite humidity in.

Foundation repair

Foundation repair can also be taken care of by a basement contractor. If there are cracks in your foundation, it's important to take care of them before moving forward with basement renos. 

Basement finishing

Of course, your basement contractor can finish a basement! This will only be completed once all preliminary steps are taken care of (i.e. all that is waterproofing). The possibilities are endless. A basement contractor can turn your space into a rental property, or any kind of space your family can make use of!

How much does a basement contractor cost? 

This all depends on their level of expertise and the size of your basement. The work they complete can cost anywhere between $45-$60 per square foot. Though, this can vary depending on the complexity of the work you're getting done and the materials being used. Are you simply finishing your basement? Or are you adding a bathroom or kitchen?

On average, a basic basement reno can cost anywhere between $25,000 and $35,000. If you choose to add that bathroom or kitchen, costs can rise quite significantly. For a more detailed breakdown of basement renovation costs, take a look at our Basement Renovation Cost article. 

How to find the best basement contractors in your area

Finding the right basement contractor doesn't need to be tiresome. You might have friends, family, neighbours, that have worked with one in the past. But, that doesn't necessarily mean they're the right one for you. It's important to trust your gut when picking a contractor to work on your basement renovations and/or finishing. After all, you'll want the entire experience to be pleasant and the results to reflect your desires.
