Questions Our Customers Often Ask About Basement Renovations

Here are some of the most common questions we receive from our clients, along with our insights to help you confidently navigate a basement renovation. If any of your questions are not answered here, feel free to fill out a form or call us directly and we would be happy to assist you.

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 by-laws 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 to $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.

At Sosna, we provide a detailed and transparent fixed quote for your basement renovation project.We provide 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 basements’ unique conditions and roadblocks. Some of the common issues that you should look out for during basement renovations 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. At Sosna, 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. At Sosna, 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 everyday.
  • 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 a kitchen. At Sosna, 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 renovation. 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.

At Sosna, we have the expertise and experience to add a bathroom to your basement renovation. We manage every step of your project ensuring a worry-free experience.

Any type 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.

Renovate

Your renovation journey should be exciting, not stressful. Thanks to our detailed planning and skilled tradespeople, there are no surprises at the end—just pure joy. 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. While we don’t offer these services to the general public, we’ll gladly help you with anything your home needs, even after the warranty expires—whether it’s mounting a picture or fixing a leaky faucet. 

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.

Design

It all starts with a simple, no-pressure conversation – a phone call or Zoom chat. We believe in finding the right fit for both of us. Not every project or homeowner is the right fit for every contractor, and not every house is feasible to renovate. We want to quickly understand your vision, budget, and priorities, and see if we can add value to your project. If not, we’ll happily refer you to a company that might be a better match. If it seems like a good fit, we’ll schedule a free in-home consultation to discuss your project in more detail. This is our opportunity to exchange ideas, share our expertise, and offer honest advice on how best to bring your vision to life.

Consult

As the saying goes, “An hour of planning can save you 10 hours of doing.”  We take this philosophy to heart at Sosna. Our designers and construction experts collaborate and work closely with you to create highly detailed plans and renderings, leaving no detail to chance.  We meticulously consider every element of your project, from layout and materials to lighting and fixtures. 

Our designers educate you on the pros and cons of every element or fixture, helping you make the right decisions.

This upfront investment in planning ensures a smooth and seamless renovation experience, free of surprises and last-minute changes.
