Basement Renovation FAQ

What services does our company provide for basement renovation?

Project Demo & Estimate. Before beginning a basement renovation, our specialist visits the client’s home for a preliminary project cost estimation. This free procedure includes a presentation of the company’s capabilities, discussion of ideas, and customer’s wishes.

Preparing the estimate usually takes no more than 45–60 minutes. During this time, in addition to presenting the company and discussing ideas, a 2D-plan of the living space and a 3D-sketch of the basement are created, and the preliminary cost of the entire project is calculated. The only thing left is to sign the contract and make a down payment.

Framing, Electrical, Plumbing. Before starting the main part of the work, it’s often necessary to fix cracks in the foundation, which can appear even in not very old private homes, typically due to regular contact of the foundation with water. It’s better to address these issues before beginning basement finishing.

The basic part of the project inevitably includes framing, the complexity and cost of which depend on the area of the house and the need to create separate rooms. Electrical and plumbing work is also carried out, usually calculated based on the number of points planned in the project.

Drywall, Plastering. The next step involves installing drywall on the wooden frame. The complexity of this task usually increases with the number of walls in the space, especially when creating separate rooms for a bathroom, bedroom, home office, and many other spaces.

At this stage, plastering work is performed, the complexity of which depends on the number of walls to be treated in the basement. Open concept layouts and shared spaces are often used in planning basement renovation projects.

Sanding, Primer, Paint, Ceramic. The final stage includes sanding, priming, painting, laying ceramic tiles, flooring, and other operations. These differ not only in the area of the space but also in the materials chosen for the finishing of each room.

Complete basement renovation usually takes about 2-3 weeks. However, the timeline may increase if a large number of custom elements are used or if additional permits are required for a legal basement apartment and more. This also significantly impacts the price.


Why is it important to choose the right company for basement renovation?

Extensive Experience in Renovation. Finished Basement has over 27 years of operation in Canada. The owner, with more than 40 years of renovation experience, oversees the quality of work at every stage. Most team members have been with the company for decades.

This experience enables the company to execute all tasks swiftly and efficiently. A basement renovation project typically takes 2-3 weeks. The only factors that might extend this timeframe are obtaining permits for a legal basement apartment or the inclusion of numerous custom elements in the project.

Large Showroom and Material Warehouse. Finished Basement is a One-Stop-Shop that can save you 2 to 3 days of your time. This efficiency is thanks to our massive 3000 sq ft showroom, where spending just 45 minutes is enough to finalize all details of the upcoming renovation.

How long will it take to complete a basement renovation project?

The execution of a basement renovation project typically spans 2–3 weeks. This duration generally covers all preliminary operations and the final finishing. Delays may occur if additional time is needed to obtain documents for a legal basement apartment or due to the integration of numerous custom elements in the renovation.

Our team of experts, with extensive experience, will meticulously plan and execute a full basement renovation using cutting-edge materials and the highest level of craftsmanship. Our primary focus is to deliver top-quality results in every basement renovation project.

Is it true that basement renovation is best done in the summer?

Like most other construction and finishing projects, basement renovation & basement finishing is not dependent on outdoor weather conditions or the season. Therefore, there is no need to wait for specific temperatures or particular seasons like spring, summer, or autumn to start these projects.

During all technological operations in basement renovation & basement finishing, non-toxic materials are used, as well as low-VOC (Volatile Organic Compounds) paint, which do not require regular ventilation of the space during the work process.

Do you help design the layout of the basement?

Unlike many other basement renovation companies and contractors, we offer absolutely free layout planning and project estimation for basement renovations. Our specialist will demonstrate how to transform a dark and dingy basement into a comfortable living space for all family members.

Before beginning a basement renovation, our specialist visits the client’s home for a preliminary project cost estimation. This free procedure includes a presentation of the company’s capabilities, discussing ideas, and the client’s wishes.

Compiling the estimate typically takes no more than 45–60 minutes. During this time, besides presenting the company and discussing ideas, a 2D-plan of the living space, a 3D-sketch of the basement is created, and the preliminary cost of the entire project is calculated. The only step left is to sign the contract and make a down payment.

Thanks to Finished Basement, you can add 20–30% extra space to your home, which can be utilized in any way you see fit. Plus, if needed, you can also create a legal second unit, which can be rented out for additional income.

What are the benefits of basement renovation?

20–30% More Personal-Use Space. Implementing a basement renovation project significantly expands usable space. It can be used for a variety of purposes — from creating additional living space to establishing a home office.

Additional Space for Night Guests. Expanding living space can include adding an extra bedroom for relatives, friends, or other guests. A basement bedroom can also provide a permanent space for a nanny.

Legal Basement Apartment Income. Remodeling a basement into a legal apartment can provide a continuous source of extra income. With increasing rental costs in Ontario, such a project can be financially rewarding.

Total Real Estate Value Increase. A basement renovation project inevitably raises the overall value of the property. After various upgrades, the house’s value can sometimes increase by up to 70%, quickly offsetting renovation costs.

What are popular ways to use your basement?

Before starting a basement renovation, it’s important to determine the intended use for the space. There are two key options: creating a dream basement for personal use or a legal secondary suite for rental.

The intended purpose of the space should guide any basement renovation project. This will influence the choice of elements and the division of space into separate areas. Here are some ideas to help decide on future renovations:

Do we provide construction materials or do clients need to find them on their own?

Unlike the majority of basement renovation companies and contractors, Finished Basement not only specializes in basement renovation & basement finishing but is also a producer and importer of construction materials and other necessary renovation items.

On one hand, this allows us to offer our clients the best prices. On the other hand, all materials needed for the renovation are readily available in our Ontario warehouses. There’s no need to order them from other Canadian provinces or abroad and wait for a long time.

Do we assist with permits for basement renovation?

Some basement renovation projects require obtaining building permits. This is particularly true for creating a legal secondary suite, which can be rented out for regular additional income to help pay the mortgage or other expenses.

Unlike many other basement renovation contractors, our company assists in obtaining the necessary building permits for basement renovation & basement finishing, as well as all related inspections. This helps in creating a cozy and functional living space without unnecessary time expenditure.

Is it worth doing basement renovation if the basement is damp?

Many basement renovation companies overlook this issue, convincing clients that it’s not a serious problem. Consequently, we often encounter clients who feel dampness even after basement renovations, including remodeling and finishing.

In reality, if dampness is felt in the basement or there are signs of moisture on the walls, it’s crucial to address this issue before starting the basement renovation. To create a comfortable living space for any purpose, it’s important to first conduct a foundation inspection and take care of any cracks in it.

Is basement renovation a good investment?

Basement renovation is one of the best real estate investments today, as it can significantly increase the value of your home if you decide to sell. With the right approach, the value of a private home after basement remodeling can increase by up to 70%, especially since the basement can be rented out for profit.

A finished basement can be a decisive factor in closing a deal. The possibility of renting out the basement, using it as additional living space, or setting up an extra bedroom for a nanny while the children are very young, is highly valuable.

What common mistakes in basement renovation should be avoided?

There are several mistakes to avoid before starting a basement renovation. Some companies don’t inform their clients about these issues to reduce costs, leading to difficulties post-renovation.

Problems that should be addressed include inadequate or incorrect waterproofing, ignored foundation cracks, and poorly planned lighting. A reliable contractor will always prioritize addressing these issues to avoid future complications.

How to estimate the budget for basement renovation?

The most accurate way to estimate basement renovation cost is by obtaining a free basement renovation estimate. Simply contact our company by phone or through one of the many forms on our official website. Our specialist will visit your home and perform all necessary calculations.

More details on this topic can be found on the basement renovation cost page. It’s important to understand that sometimes adjustments in the cost may occur, as with basement renovation projects in Toronto, which often face challenges in accessing the property or poor foundation conditions.

In any case, we understand the importance of having all figures before starting a project. Our estimated cost for basement renovation includes both the price of materials and labor. This level of detail is not offered by all basement renovation contractors in Ontario.

You will receive an estimate with a breakdown of construction aspects. This helps you make a more informed decision about the overall plan for basement remodeling. We offer a completely free cost estimate for the renovation and creation of a living space without any obligation, so our clients can work with us confidently.

Is it possible to finance basement renovation?


Finished Basement Company offers home equity loans to help realize basement renovation projects of any complexity. You can get your dream basement for just C$150–300 bi-weekly through a partnership with FinanceIt Canada Inc.

This applies to both basements for personal use and basement apartments. A legal unit can be rented out immediately to generate income, covering the difference between the monthly loan payment and the high, ever-increasing rent. More information about basement renovation financing is available on our dedicated page.

Is it possible to convert an already finished basement into a legal second unit for rent?


Creating a second unit involves specific material requirements. For a second unit, fire-rated drywall, fire-rated doors, and other fire-resistant materials are necessary. Additionally, a legal basement apartment must be equipped with a smoke detector.

Furthermore, converting to a second unit for rent involves regular inspections by inspectors. They check the correctness of the legal basement apartment project at different stages to ensure its safety for tenants and homeowners.
