Basement Renovation Services Types
- General Basement Renovations. Basement renovations involve converting neglected or unfinished basements into appealing and operational spaces. Creative conversion ideas span from guest suites, home gyms, and extra storage, to laundry rooms, wine cellars, bars, and home theaters. The financial investment in such renovations, dictated by factors such as basement condition, material quality, finishes, extra amenities, and labor, is typically offset by a potential 7% increase in property value.
- Basement Finishing. It involves establishing vital elements like drywall, soundproofing, plumbing, sufficient ventilation, certified exits, and flooring, in compliance with building standards. Unlike renovations, basement finishing breathes life into a bare basement. Its perks are manifold: extending the living space by up to 50%, fostering a healthier indoor environment, and presenting the potential for diverse utility.
- Basement Underpinning. Basement underpinning targets the augmentation of basement foundational strength and additional vertical space, setting the stage for further renovations. It involves methodologies such as converting crawl spaces into habitable lower levels or employing bench footing. In places like Toronto, underpinning necessitates a thorough understanding of foundational construction, local building norms, and soil types.
- Legal Basements. Legal basements in Markham are spaces that adhere to local building codes, ensuring resident safety and maintaining property value. Distinct from typical basements, legal basements satisfy crucial safety, zoning, and structural norms. Modifications must comply with the Ontario Building Code and Electrical Safety Authority regulations.

CSG did an amazing job on renovating my basement. Work was fast, efficient and they helped point out some space saving changes that really helped maximize the space. The basement addition involved adding a bathroom, doing a complete reno of the space including living room, office, storage rooms, electrical room and Exercise room. The work was finished professionally and very fast. I’ve dealt with a number of workers in the past and these have been the best I’ve worked with. Highly recommended.
Their work exceeded my expectations. I finally found a professional renovation company I can confidently rely on. They did a complete floor replacement in all rooms and paint throughout. Communication was always clear and prompt. Owner, Zeev and his team worked with my special requests and the results were outstanding. Not a single detail was overlooked and I could not find a single flaw in the workmanship. They left everything spotless. It all looks amazing. Bonus; all the work was completed under the estimated time frame and I was very pleased with the reasonable cost of the entire job. CSG Renovation ticks all the boxes. Thank you Zeev!
We had a great experience working with Zeev! His team actually finished our condo renovations ahead of schedule and the quality of their work was excellent. I would recommend CSG and work with them again. Reasonably priced and a job done right. Thanks Zeev!

Why Us
Yes, in Markham, you typically need a permit to finish a basement, especially if you’re changing the structure, altering the plumbing or electrical system. We assist our clients in understanding and acquiring the necessary permits.
You might want to reconsider finishing a basement if there are serious structural issues, excessive moisture problems, or if the basement regularly floods. We can help you identify these problems and provide a professional assessment of the feasibility of your renovation.
Homeowners can prepare by clearing out the basement, making decisions about the design and function of the space, setting a realistic budget, and be prepared for some disruption while we renovate your basement.
It’s generally cheaper to finish a basement than to add a second story because fewer structural changes are needed. Adding a second story involves altering the home’s foundation and structure, resulting in significant costs comparable to creating a new basement.
Unexpected issues can include the discovery of mold, pests, or structural damage that wasn’t apparent until the renovation began. Plumbing or electrical issues can also arise if these systems are outdated or improperly installed.
We offer comprehensive services, including basement design. Our experienced team of designers can work closely with you to ensure that the final result matches your vision and needs. However, if you prefer to hire a separate designer, we’re flexible and ready to collaborate.
We’re committed to minimizing disruption and damage to the rest of your home. This includes using dust barriers, protecting floors, cleaning up our work area at the end of each day, and carefully scheduling work to minimize noise and disturbance.
Yes, at CSG Renovation we stand by our work. We offer maintenance and follow-up services to ensure that you are fully satisfied with the outcome and that the renovation holds up over time.
We typically use spray foam or rigid foam board insulation in basements, as it provides superior moisture control and thermal resistance. Good insulation reduces energy costs by preventing heat loss in winter and keeping the basement cool in summer.
We have rigorous project management processes in place. This includes detailed planning, budgeting, and scheduling before work begins. We then monitor the project closely, communicating with you regularly to ensure that we stay on track.
Older homes can present challenges such as outdated electrical and plumbing systems, structural issues, and possible presence of hazardous materials like asbestos. Our team is experienced in dealing with these issues and we take all necessary precautions during the renovation process.
At CSG Renovation, we prioritize safety above all. This includes using personal protective equipment, ensuring safe use of tools and equipment, adhering to local building codes, and maintaining a clean work site to prevent accidents.

Renovating your basement is likely to increase the square footage of your house. It also impacts the value of your home. The basement can be converted into a living room, a bedroom, or even a play area.
But there are many factors to put into consideration when converting your basement into a living space.
With the concrete walls and floor, you most probably think that your basement has no value. This is not the case. With a good finish, the value of your home is likely to go up. Homes with good basement finishes fetch a fortune in Toronto. It is therefore important that you find out what it will cost you to finish the basement by either hiring a contractor or opting for DIY.
Maybe you just bought a new home or didn’t have the time to finish your basement stairs; whatever the case, the state your stairs are in is no longer acceptable to you.
Don’t worry. It’s common among homeowners to leave this step to be finished later. However, putting it off ’til later can make its design and execution seem like an afterthought. Just because it’s in your basement doesn’t mean no one will ever see it. Read on below if you are in the mood to revamp your basement, starting with its stairs!
