Redefining Basement Renovations
Renovating a basement is more than construction and design. It takes innovation and creativity. Harmony Basements specializes in merging fine detail with exquisite design and structural integrity to achieve stellar results. We use advanced technology to create elaborate virtual tours that allow our clients to see exactly how their new basement will look when it’s complete.
Most contractors are focused on getting the job done as quickly and simply as possible. In their attempt to maximize their profit margins, they often cut corners and shortchange homeowners. Not us. Harmony Basements takes a customer-focused approach to renovation projects and offer comprehensive solutions that keep homeowners at the center.

Crafting Stunning Basements with Care, Precision, and Passion
We start by using advanced technology to create elaborate virtual tours that allow our clients to see exactly how their new basement will look when it’s finished. This not only helps them visualize the end result, but also allows them to make informed decisions about the design and layout of their new space.
Once we have a clear understanding of our client’s vision, we work diligently to offer a variety of design options based on their preferences. We don’t believe in a one-size-fits-all approach, so we take the time to listen and understand our client’s needs.

WE SIMPLY LOVE BASEMENTS
At Harmony Basements, we believe that a basement should be more than just a storage space or a place to do laundry. It should be an extension of your home and a reflection of your personal style. We’re passionate about helping our clients transform their unfinished or outdated basements into beautiful, functional, and inviting spaces that they can enjoy for years to come.
We’re also committed to quality and integrity in everything we do. We don’t cut corners or use subpar materials to save money. Instead, we only use the highest quality materials and employ skilled craftsmen who take pride in their workmanship. This ensures that every project we complete is not only beautiful but also built to last.
We believe in the transformative power of a well-designed and well-built basement. We’re passionate about helping our clients achieve their vision and creating spaces that they’ll love for years to come.

The safety of residing in your home during a basement renovation depends on the specific project and the potential hazards involved. Consult with Harmony Basements to determine the best course of action for ensuring a secure living environment during the renovation.
Rain, snow or shine, we work all year round, including winter.
While conventional construction materials such as lumber, drywall and fibreglass insulation work great for above-ground construction, these products can rot and cause mould in high-moisture areas like basements. Our mould-repellent products such as Magnesium Oxide Wallboard allow moisture to pass through naturally to prevent mould from growing. The materials we use are top-of-the-class to prevent mould and mildew. Also being fire and waterproof, sound-absorbent and eco-friendly, they are designed for the safest and most comfortable living environment. We use only the best materials – that is the Harmony way.
We highly recommend choosing our handpicked selection of Torlys Luxury Engineered Vinyl Floor for lifetime durability and to withstand environmental factors that typically change the structure of natural hardwood.
