Strengthen Your Foundation

Basement Renovation

Transform your basement into a modern, functional living area tailored to your lifestyle and needs.

What is a Basement Renovation?

A basement renovation transforms an unfinished or outdated lower level into a fully finished, comfortable living space. From framing and insulation to flooring, lighting, bathrooms, and kitchens, we manage every detail to create a room that functions as a true extension of your home.

Whether you’re planning a family room, home office, or income suite, we tailor the layout and finishes to suit how you live and the value you want to add.

Why Renovate Your Basement?

Add functional living space to your home

A finished basement gives your family room to grow — a rec room, office, gym, or guest suite — without the cost of moving or building an addition.

Build a legal income-generating suite

With the right design, permits, and finishes, your basement can become a code-compliant rental unit that helps offset your mortgage.

Customize the layout to your needs

We work with you to plan a space that fits your lifestyle and budget, from open-concept living to dedicated bedrooms, bathrooms, and kitchens.

Increase comfort, efficiency & value

Proper insulation, moisture control, and modern finishes make the space more comfortable to live in and more valuable when it’s time to sell.

The best service I ever got. The owner of the company came in person before and after the job was done. Great customer service. The job was done fast and the best quality. Very impressive. I would recommend anyone who needs job done fast and headache free. As a side note the payment process was all automated. That part was also fast. Unbelievable. I will definitely contact for my next project. Thank you!

Our older, lower (6′), mostly finished basement needed to be expanded to allow for an elderly family member to join our household. Rock Bottom came recommended by a friend of a friend and did not disappoint. The price was competitive (but not cheap) for gutting the basement, taking our floor down to get us a finished height of 8′ with new drains, sump pump, backwater valve and hot water heating pipes with manifold. The team was always punctual (6 days a week), always cheerful, and highly effective. From start to finish their work took 5 weeks (the estimate was 4-6). Our GC noted how rare that is with underpinning work, and a builder friend noted the quality of the floor’s finished surface. Additionally, our semi-detached neighbour’s basement is almost finished (the team is still punctual, cheerful and effective).

Rock Bottom renewed my faith in contractors. They were unbelievable responsive, available to answer all of my questions at every step. The crew was early every day and put in long hours to get the job as quickly as possible. There were a couple of surprises discovered when they dug down and none of it impacted the price I paid. The crew was friendly, happy, and incredibly hard-working. I cannot recommend Rock Bottom highly enough. I’d hire them again in a heartbeat. I’m thrilled with my new basement!

So happy we chose rock bottom for our underpinning project. The team was amazing and did an incredible job. Throughout the project they were in constant communication with us and when they were finished, left the site in perfect condition.
