Testimonials

See why homeowners trust our team for quality basement renovations, honest service, and outstanding project results.

     

 Maple Leaf Basement transformed our unfinished basement into a beautiful family room. The team was professional, punctual, and kept us informed throughout. The finished space is warm, well-lit, and our kids use it every single day. Exactly what we envisioned. 

Sarah L.

 We engaged Maple Leaf specifically for design and permit management before bringing in our own construction team, and the experience was outstanding from the very first consultation. Their drawings were complete, accurate, and fully OBC-compliant, approved on first submission with no comments or revision requests from the city building department. The permit process that we had dreaded turned out to be entirely stress-free because their team managed every communication and every inspection scheduling on our behalf. Their knowledge of Hamilton's specific permit requirements saved us weeks of back-and-forth and kept our project on schedule. We would not hesitate to recommend their design and permit service to any GTA homeowner.

 Maple Leaf handled everything - design, permits, construction, and registration. Our legal basement apartment was completed on time and rent-ready at handover. We found a tenant within two weeks. The rental income already covers our monthly financing payment. Best investment we have ever made in this home. 

David K.
Toronto
     

 We needed a comfortable and private guest suite for visiting family members who stay with us regularly. Maple Leaf designed a bedroom, ensuite bathroom, and sitting area that functions beautifully as a self-contained space. The finish quality is excellent throughout - flooring, drywall, trim, and fixtures all done to a high standard. Our family loves staying there and always comments on how comfortable and well-designed it feels. Professional team, clean job site every day, and no surprises on the final invoice. Exactly as quoted. 

Lisa C.
Hamilton
     

 We wanted a proper home theatre, not just a television on a wall. Maple Leaf delivered exactly that - tiered seating, acoustic insulation, dimmable lighting, and full equipment integration. The result exceeded every expectation we had going in. Our family has not visited a movie theatre since it was completed. 

Jennifer M.
Vaughan
     

 Maple Leaf finished our basement with an open entertainment area and a custom wet bar that has become the centrepiece of every gathering we host. The cabinetry, countertop, plumbing, and lighting are all beautifully executed and clearly built to last. Every guest who visits comments on how impressive the space looks and feels. The team was skilled, organized, and communicative throughout the entire project. They delivered exactly what we discussed during the design phase without a single surprise. 

Robert H.
Whitby
     

 Maple Leaf built our below-grade separate entrance from excavation through to final finishing. The team was knowledgeable, code-compliant, and thorough at every stage. The finished entrance looks clean and blends beautifully with the home exterior. They managed every permit and inspection without any involvement from us whatsoever. A completely seamless experience from start to finish. 

Michael T.
Scarborough
     

 We were genuinely nervous about navigating the permit process for a legal basement suite. Maple Leaf handled every application, inspection, and municipal registration without us making a single call to the city ourselves. The finished unit is modern, functional, and beautifully finished throughout. Our tenant moved in the week after handover. The rental income has already made a meaningful difference to our monthly household budget and we could not be more satisfied. 

Christine W.
Markham
     

 Adding a bathroom to our basement made a significant difference in how our family uses the space every day. Maple Leaf managed the plumbing permit, rough-in, and full finish without a single issue arising. The 3-piece bathroom is beautifully tiled, well-designed, and exceeded our expectations in every way. Worth every penny and then some. We could not be happier.

Basement Ideas That Inspire
Basement Ideas
Not sure what you want to do with your basement? That's exactly where we start. At Maple Leaf Basement, many of our best projects began with a homeowner who simply knew they wanted to do something with the space, but hadn't yet decided what.

Your basement could become:

  • Family room or entertainment space — the most-used room in your home
  • Home theatre — designed for the experience, not just a big TV in a box
  • Home office or workspace — proper separation, lighting, and focus
  • Home gym — always available, always private, never crowded
  • Guest suite or in-law space — comfortable, private accommodation for family
  • Wet bar and entertainment bar — the destination for every gathering
  • Playroom or children's space — contained, bright, and built for creativity
  • Legal basement apartment — generating $1,500–$2,800/month in rental income
Simple Process. Stunning Results.
Our Process
Uncertainty is one of the biggest sources of renovation stress. At Maple Leaf Basement, our four-step process is designed to make your project clear and manageable from the first conversation to final handover. We don’t pretend complications never happen; we plan carefully, communicate clearly, and manage them professionally at every stage. From first consultation to finished basement:

  • Step 1 — Consultation & Estimate: Free consultation, site assessment, project goals, scope, budget discussion, and detailed preliminary estimate.
  • Step 2 — Design, Drawings & Permits: Functional layout planning, design development, required construction drawings, and coordination of applicable permit applications and approvals.
  • Step 3 — Construction & Inspections: Professional construction, coordinated trades, project updates, quality control, and coordination of required municipal and applicable inspections.
  • Step 4 — Project Handover: Final walkthrough, completion review, outstanding-item closeout, applicable permit and inspection documentation, and workmanship warranty information.

FAQs

Find answers to common basement renovation questions and make informed decisions with confidence before starting your project.

Maple Leaf Basement specializes in three core services: regular basement finishing and renovation - transforming unfinished or outdated basements into family rooms, home theatres, gyms, offices, and guest suites; legal basement apartment construction - fully permitted, OBC-compliant secondary suites that generate $1,500–$2,800/month in rental income; and complete design, drawing, and permit management - the full pre-construction planning and permit administration service that supports both. Basements are all we do, and that singular focus makes us better at it than any general contractor serving the GTA.
Regular finishing ranges from $40–$60+ per sq ft for a basic open-plan finish to $100–$130+ per sq ft for premium custom elements. A standard 700 sq ft finish with a 3-piece bathroom typically runs $50,000–$70,000+. Legal basement apartments start at $90,000–$130,000 for standard conditions and $130,000–$200,000+ for complex conditions requiring underpinning or significant waterproofing. Every Maple Leaf Basement estimate is detailed, itemized, and based on an in-person site assessment - provided at no cost and no obligation.
Regular finishing for 600–900 sq ft typically takes 6–10 weeks from construction start. Legal basement apartments require 10–16 weeks of construction plus 4–8 weeks for permit approval. Premium custom renovations can run 12–22 weeks. Legal suites requiring underpinning add 4–8 more weeks to the construction phase. Design and permit phases precede construction in all cases. We provide a detailed project schedule before any work begins and communicate any adjustments proactively throughout the project.
Most GTA basement renovations require a building permit and often ESA and plumbing permits. Any new habitable space, structural modifications, new plumbing rough-ins, or electrical work requires permits. Legal basement apartments always require all three permit types - building, ESA, and plumbing - plus municipal registration at completion. Maple Leaf Basement manages every permit stream completely in-house, from first application through final close-out. You never contact a building department yourself at any stage of your project.
Yes, in almost all cases. Basement renovation is below grade and does not require homeowners to vacate. We use dust containment measures at the stairwell throughout construction and clean up daily. The vast majority of GTA families remain comfortably in their homes for the full duration of their basement project. We manage the job site to minimize disruption to your household's daily routine from start to finish.
Yes. Every completed Maple Leaf Basement renovation is backed by a written 1–2 year workmanship warranty delivered at project handover - not a verbal assurance, not fine print. Any defect in our workmanship identified within the warranty period is corrected at no cost to you. Our warranty is backed by a licensed, insured, WSIB-compliant company with a verifiable track record of completed GTA basement projects. When we hand over your finished basement, we stand behind it in writing.
Yes, and every credential is verifiable on request before you sign anything. We carry General Commercial Liability insurance protecting your property throughout construction. We are fully WSIB compliant, eliminating your injury liability exposure. All electrical work is performed by licensed electricians under ESA permits. All plumbing is performed by licensed plumbers with required permits. BCIN-qualified designers prepare all permit drawings. We provide all documentation without hesitation, ask any contractor you are evaluating for the same.
Yes, completely free with no obligation to proceed. Our estimate process includes a free in-person site visit to assess your specific basement, a thorough discussion of your goals, budget, and timeline, and a detailed written estimate itemizing every scope element individually. What we quote is what we expect you to pay - no hidden costs, no vague line items, and no surprise additions once construction begins. No cost, no pressure, and no obligation to move forward.
Yes, by up to 5% when the comparison is genuinely equivalent: same scope, same materials, same licensed trades, same permit management, and same workmanship warranty. We do not compete with quotes that skip permits, use unlicensed workers, or carry no warranty, those are not equivalent quotes. They are a significantly riskier product. If you have received a lower quote for a genuinely equivalent scope, contact us and we will review it.
Contact Maple Leaf Basement today for a free, no-obligation consultation and detailed written estimate. Reach us by email at maple.leaf.basement.renos@gmail.com, through our website at mapleleafbasement.ca, or by filling out our online estimate request form. We respond to all inquiries within one business day, schedule a convenient in-person site visit, and deliver a detailed written estimate at no cost. The first conversation costs nothing, and it leaves you with a clear picture of what your basement could become.
