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 Ajax, 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.
