The contractor you choose

It’s essential to choose the right craftsperson for your basement. Carry out due diligence and make sure you are selecting a trusted and honest builder. Some things you may want to examine when choosing a contractor include:

  • Their experience with basement finishing: how many years have they been in the basement finishing business?
  • The quality of their work: do they charge less than their competitors because they buy the cheapest materials?
  • How they handle customer service and complaints: do they take a receptive and pragmatic approach to queries and critiques, or are they hostile if they feel their work is being discredited?
  • The amount of time they estimate the project will take to complete: make sure they offer you a realistic timeframe, especially if you have a busy schedule of your own. The worst thing you should want is to be given a 6-week turnaround, only to find out the project takes 12 weeks for whatever reason.
  • What type of assurance do they offer on their work: as a paying client, you are entitled to certain rights—the right to a completed finished basement for starters. Also, you have the right to be safe in the knowledge that if there are any incidents resulting from the work that was carried out, you will be compensated accordingly or that repairs will be made immediately.
  • Before a contractor begins any renovation, a 90-day guarantee is generally required. Make sure you ask about this when speaking with your contractor. This way, if anything major goes wrong after the work has been completed, there will be enough time to open up a dispute and have it resolved before the warranty expires.

The contractor’s experience

When it comes to finishing a basement, it’s important to hire a contractor who has extensive experience in the field. This is not an undertaking that ought to be overlooked – it can be very tricky to get everything just right, and if something goes wrong, it can cost a lot of money. Plus, if you’re not familiar with the process, you could easily make a mistake that would be costly and difficult to fix.

That’s why it’s principal to find a contractor who knows what they’re doing. Preferably, you want someone who has been doing this for a while and has a good track record. This way, you can be sure that the job will be done well and that any potential problems will be avoided.

Fees and permits required

When you are planning to finish your basement, it is important to have a frank and upfront discussion with the contractor about all the expenses that you will incur. This includes the cost of the materials and labor and any permits or inspections that may be required. It is also essential to verify that you are clear on what is included in the contractor’s estimate and the additional cost.

It is critical to consider that there can be a lot of hidden costs when finishing a basement, so it is best to be as prepared as possible. By having a clear understanding of what to expect, you can avoid any surprises down the road.

Disposal of waste

Making sure you and your contractor agree as to who is responsible for waste disposal during and after the project is essential. This will help to steer clear of any uncertainty or disagreements down the road.

How Do Contractors Charge?

Some contractors charge for the project. Others charge by the hour. And others charge a flat rate, which may sometimes be negotiable, depending on the extent of the work that needs undertaking and how much they think it will cost them for materials and time.

By the hour VS flat fee

Hourly contractors usually charge more than those who charge a flat fee, but the total cost may be lower if the job takes longer than expected. A contractor who charges by the hour may also be less likely to rush through the position to make more money. However, a contractor who charges a flat fee may be more likely to take shortcuts to make more money.

Ultimately, it is down to the homeowner to conclude which option is best for them. However, it is possible to find out which type of contractor you are dealing with by asking these questions during the initial meeting.

  • What if the basement finishing project takes longer than expected?
  • What happens if hidden problems arise that result in additional costs?
  • What if the job doesn’t end up looking like how you imagined it would?

If the contractor charges by the hour, this should not be a problem because you will simply pay them an hourly rate for the amount of time they have worked. If the contractor charges a flat fee, it is crucial to get everything in writing to avoid misunderstandings later on.
