Our Basement Renovation Process

At SOSNA, we adhere to a strict and detailed process to ensure a stress-free renovation journey for our clients. Our approach eliminates construction delays, surprises, and price creeps.

Step 1 - Consultation

Step 1 - Consultation

This first meeting is crucial to lay the foundation of a successful basement renovation and to establish a strong working relationship. We determine if we are the right fit for each other and our team visits your home to assess its current condition. We then discuss your vision, objectives, expectations, and budget for your basement transformation. Based on these discussions and our expertise, we provide you with a preliminary cost estimate.

Step 2 - Design

Step 2 - Design

In this phase we match you with an in-house designer, project manager and estimator who prepares a detailed scope of work and drawings for your basement renovation. We conduct a comprehensive house inspection to pre-emptively identify potential obstacles, ensuring a smooth construction process. We pride ourselves on maintaining close collaboration with you throughout the design phase and promise to deliver you a perfect balance between design and budget.

Step 3 - Quote

Step 3 - Quote

Once the design is finalized, we prepare a renovation agreement that includes a fixed-price quote, a comprehensive and detailed scope of work, and payment and construction schedules. Our team is committed to providing unparalleled quality and value, and collaborating with you to ensure the project remains aligned with your budget. The quote we offer encompasses all project specifics and will not increase throughout the basement renovation process. That is our promise to you.

Step 4 - Construction

Step 4 - Construction

Your dedicated project manager oversees the entire project, and an on-site supervisor ensures construction advances smoothly and on schedule. We prioritize limiting disruption to your daily life and maintaining a clean, safe working environment. And we extend continuous support to you throughout the project and beyond, including daily briefings from the supervisor, weekly updates form project manager, history record via daily logs and project photos. Then all that’s left is to enjoy your new space!

Questions Our Customers Often Ask About Basement Renovations

Do I need a permit for a basement renovation in Toronto?

Generally speaking, you will need a permit if you are making any structural changes, adding or removing walls, installing or altering plumbing or electrical systems, creating a separate dwelling unit, or changing the use of the space. Minor renovations may not require a permit.

At SOSNA, we are familiar with the local municipalities we service and their bylaws and regulations and can help you obtain the necessary permits for your basement renovation project. We will work with you to ensure a stress-free and smooth process.

The cost of a complete renovation of a 1,000-square-foot basement costs anywhere between $80,000 and $150,000. The cost will differ based on various factors, such as the size and condition of your basement, the design and layout of your new basement, the materials and finishes of your choice, and the complexity and duration of the project.

When you work with us, we will provide a detailed and transparent fixed quote, and a detailed and thorough scope of work that covers every aspect of the project. And we promise that our price will not increase during construction.

Basement renovations can be challenging due to their unique conditions and roadblocks. Some of the common issues that you should look out for are:

  • Moisture and mould: Basements are prone to moisture and mould problems due to the lack of ventilation, natural light, and drainage. Moisture and mould can damage your basement’s structure, materials, and health. During our basement inspection and excavation, we will ensure your basement is adequately waterproofed, insulated, and ventilated.
  • Low ceilings: Basements often have low ceilings that can limit the design and layout of your new basement. Low ceilings can also make your basement feel cramped and dark. We are experts at maximizing your existing space and, if necessary, can increase the height of your basement by removing any unnecessary bulkheads, ducts, and pipes, or underpinning it.
  • Supporting posts: Basements often have supporting posts that hold up the main floor of your house. These posts can interfere with the design and layout of your new basement, especially if you want to create an open-concept space. At SOSNA, we deal with structural alterations every day to help our clients maximize the design and layout options.
  • Sewer lines: Basements often have sewer lines that run under the floor or along the walls. These lines can affect the plumbing and drainage of your new basement, especially if you want to add a bathroom or kitchen. During our basement inspection, we will locate and inspect the sewer lines and, if necessary, consult with a plumber if we need to relocate or modify them.

At SOSNA, we have the expertise and experience to deal with common issues experienced during basement renovations in Toronto. We can identify and solve any problems your basement may have and ensure that your basement renovation project is done safely and correctly with a beautiful, functional final result.

Yes! A basement bathroom can enhance functionality and comfort, especially for separate living arrangements or guests. Adding a bathroom during your basement renovation requires obtaining permits, adhering to building codes, connecting to existing plumbing, ensuring proper drainage, and thoughtfully designing the space to prevent moisture and mould issues.

Any type of flooring can be used if your basement is finished properly. The most common flooring options for basements include vinyl, porcelain tiles, and rubber flooring. These materials are resilient against moisture and temperature fluctuations common in basements. Laminates are often used, too, but they are not moisture resistant and will usually require a subfloor or moisture-resistant underlayment. The type of flooring that our designers will choose with you for your specific project will ultimately depend on your new basement’s use, style, and budget.

A basement renovation will usually take between 6 to 12 weeks to complete, and the timeline can go up from there based on the scope of your basement renovation project. Some factors that can impact the timeline of your project include:

  • Permit: Obtaining a building permit can range from a few weeks to a couple of months, depending on the municipality you live in.
  • Design: The design can take 3-4 weeks to a couple of months based on how many revisions are required.
  • Materials: Ordering and delivering the materials for your new basement can take anywhere from a few days to a few weeks, based on availability and the supplier’s delivery schedule.
  • Construction: The actual renovation can take 6 weeks to a couple of months, based on the scope of the project.

Our proven and streamlined basement renovation process ensures a smooth and stress-free experience. Our in-house designers, contractors, tradespeople, and project managers will manage very part of your project with professionalism and excellence. We will provide you with a realistic and accurate timeline for your project and keep you updated throughout.

Our clients are often overwhelmed with happiness during the final walkthrough, and we’ve even witnessed a few happy tears! Many tell us they actually enjoyed the renovation process and will miss our team! 

Even after your renovation is complete, our commitment to your satisfaction continues. We offer a 2-year warranty on all our work and take it very seriously. Every non-urgent warranty request is addressed within two business days. This ensures that any issues are resolved quickly and efficiently so you can continue to enjoy your beautiful new space without a worry in the world.

Our clients often return to us for future projects because they know we’re there for them long after the job is done. We love hearing from them, even if it’s just for a minor repair—it’s a chance to show you how much we care. 

We aim to “wow” you with our service so you’ll confidently recommend us to your friends, family, and colleagues.

We understand how hard it can be to find reliable help for small jobs, so we go the extra mile for our clients.

Our goal is for you to enjoy the process, love the result, and have complete peace of mind knowing we’re just a phone call away.

Five years after we remodeled her Thornhill home, one of our wonderful clients told us, “Every day, I come home from work, and I can’t believe this is my house!”  That’s the feeling we strive for with every project.

We want you to feel that same joy and pride in your home now and for years to come.

Quote

Estimating renovation projects inherently involves some guesswork, but we take steps to minimize it as much as possible. Here’s how:

Crystal-clear Design Drawings: Our meticulous drawings go beyond basic sketches and floor plans. They include precise measurements, elevations, sections, and details with specifications for materials and finishes and clear layouts for plumbing, electrical, and mechanical systems. This level of detail allows us to calculate material quantities and labor hours more accurately.

Upfront Material & Fixture Selection: We work with you to select all materials and fixtures – tiles, flooring, cabinets, countertops, accessories down to the door knobs on your cabinetry – before finalizing the quote. This eliminates the need to estimate costs based on allowances, reducing the potential for surprises later.

Thorough Inspections: Before finalizing the quote, we thoroughly inspect your home’s structure, plumbing and HVAC systems, and electrical wiring. This uncovers potential unseen issues that could impact the project scope, cost, and design. By identifying these issues upfront, we can factor them into the quote, avoiding unexpected cost overruns during construction.

Only after we complete all the above-mentioned steps do we provide a fixed-price quote that we guarantee will not change during construction.
