Costs Associated with Basement Renovations

There are various costs to consider at different stages in the renovation process. If you are installing a bathroom or kitchen in your basement, the first thing you need to factor in is plumbing.


You’ll need to have a connection to a water supply and sewage lines for your bathroom. This will require hiring a professional plumber and paying for the costs associated with establishing the water and sewage lines needed. Sometimes walls have to be opened up to facilitate a water or sewer line that is convenient and may cost less.

Building permits

If you are making changes to your home, your renovation project will most likely need to be approved by your local government authority before any work can begin.


This is something you will need to have done if you are adding a bathroom to your basement. Once all the plumbing work is completed, an inspection is necessary to ensure the work done is up to par with regulations established by your municipality. Any electrical work done in connection with the renovations will also need to be inspected. This is very important because an electrical fire can break out in your home and cause damage that an insurance company may not cover. You can expect some costs associated with the inspections.


If you have a large, open basement area, you may want to consider sectioning off the space into rooms that can be used for different purposes. Erecting walls will increase renovation costs, but the added value to your home will likely make the investment worthwhile. The cost of framing is based on the following elements:

  1. the need to demolish existing walls
  2. the size of the room the needs framing
  3. whether additional walls need to be erected
  4. whether the walls need to be soundproof

Drywall Installation

Installing drywall to your walls is something you will need to do whenever you add a new wall in your basement. This step is done after framing and is critical.  One of the things that impacts drywall installation costs is the type of drywall you want to use.

Typically, drywall can cost anywhere from $3 to $6 per square foot. Once you have decided on what material you want your drywall to consist of, the next thing you will need to determine is the cost of installation. The cost is often dependent on the area you would like to install the drywall.

Installing Electrical Appliances

About $50 to $100 per hour is what you can expect to pay somebody to install any electrical appliances that require a professional. Some wiring is required in your basement to make sure the room is able to support your electrical needs. To accomplish this, you will need to hire a licensed electrician to make sure you don’t have any electrical issues with the wiring. The cost to hire an electrician will vary depending on the area you live in and their level of expertise.


Something that often gets overlooked with basement renovations is the ceiling. Unfinished basement can have unsightly ceilings that show exposed pipes and other wiring that is best left concealed. It may not be a priority for you, but some attention devoted to your ceiling can give your beautifully renovated basement the finishing touch it needs. Many homeowners take advantage of space on the ceiling to incorporate additional lighting.

The minimum height requirement for ceilings is usually 7 feet. Basement ceiling can either be suspended with tiles installed on a grid or you can have the ceiling drywalled.

Drop ceilings are an excellent choice because they provide access to utilities. In addition, replacing tiles can be done inexpensively. Drywall provides a smooth finish but makes it a little harder to access utilities lines that may need repairs. It’s a great idea add sound insulation to your ceiling, particularly if you plan to use a basement as a home theatre or game room.

A drywall ceiling will cost about $5 per square foot; a coffered ceiling will be roughly $25 per square foot; and drop ceilings will run anywhere between $2-$6 per square foot.


Renovating the floor of your basement may include a number of processes like redoing the subfloor, adding insulation and padding and then installing the flooring and baseboards. Some popular choices for flooring are tile, vinyl, carpet, engineered hardwood and laminate, while some people choose to simply add a finish to their concrete floors. The intended use of your basement can help you determine which of these following options is the best choice for you.

You can install more than one type of flooring in your basement if you have a large basement and plan to create different areas or rooms. Tiles are a great choice for wet bars and bathrooms but keep in mind that tile flooring tends to make basements cold. A cozier choice is carpet, which is perfect for home theatres and playrooms. There are also heated floors that can aid in keeping your basement space warm.

You can expect your flooring to cost anywhere from $1-$40 per square foot. If you opt for concrete finishing, the cost will run between $2 and $30 per square foot. Baseboards are an inexpensive addition and can cost between $5.70 to $8.95 per linear foot.


It is truly amazing how a fresh coat a fresh coat of paint can breathe new life into the space. Selecting the right colour for your basement walls is often based on how you intend to use your basement and your personal preference. There are some colours that are more welcoming, contribute to the brightness of the room and can make it look more spacious. Other colours can make your basement darker, which may not be a bad thing. For example, if your new basement will be a home theater, natural light may not be a priority for you.

Painting your ceilings is also an excellent way to add a nice finishing touch. On average, the cost of painting the interior of your home is about $3-$8 per square foot of floor space. Choosing to paint your basement yourself will save you some money, but you should keep in mind that painting takes time and skill.

The cost to paint your basement will also depend on a number of factors. The layout and age of the basement, code compliance issues, whether there are separate rooms that need to be painted as well, and whether there are specialty rooms to be painted. If you have an open floor layout in your basement, this will reduce the cost of painting since many painters charge based on the number of rooms being painted.


Your finished basement wall need a number of electrical circuits dedicated to the space. You will need electrical outlets in each room and at multiple points throughout your basement. Electrical circuits will also supply lighting. The number of rooms and appliances in your basement will determine how extensive your electrical network will need to be for your basement. This will require the assistance of an electrician, which will cost anywhere between $2,500-$10,000. (cost of basic electrical needs is already included into cost of basement calculator)

The state of the electrical circuits in your basement will also play a role in how much you will spend. The costs can easily climb to about $8,000.
