Toronto's Older-Home Renovation Specialists Since 1973

Toronto was built on its older homes. The Victorians of Cabbagetown, the Edwardians of the Annex and High Park, the century semis of Roncesvalles and Leslieville—these houses give our neighbourhoods their character. They were also built more than a hundred years ago, and renovating one is nothing like renovating a new build.

At Oriel Renovations, older homes are not a sideline. They are what we do. Since 1973, we have spent more than five decades learning how Toronto's century homes are put together—how they were framed, where they fail, and how to bring them into the present without erasing what makes them worth keeping. We strengthen what has already stood the test of time, and we add the comfort, efficiency, and function a modern family needs.

If your home has plaster walls, a rubble-stone foundation, knob-and-tube wiring in the attic, or a layout that made sense in 1910 but doesn't today, you are exactly the homeowner we built this company for.

In short: Oriel Renovations specializes in renovating Toronto's century, historic, Victorian, and Edwardian homes—preserving their original character while upgrading structure, systems, and livability. We've worked on older Toronto homes since 1973.

What Counts as a Century or Older Home in Toronto?

 These terms get used interchangeably, but they mean different things—and the difference affects what you can and can't do to your home. Here's how we explain it to clients. 

What It Means: 

A home roughly 100 years old or older. A description of age and construction, not a legal status. 

Renovation Implications: 

 No special permissions required beyond standard permits, but the construction methods (plaster, balloon framing, old foundations) demand an experienced older-home contractor. 

What It Means: 

Property is on the City of Toronto's Heritage Register but not legally protected. 

Renovation Implications: 

Demolition requires notice to the City; most interior and many exterior changes proceed normally. 

What It Means: 

Legally protected under the Ontario Heritage Act for architectural, historical, or cultural significance. 

Renovation Implications: 

Changes to protected features (often the façade, roofline, windows) require a Heritage Permit. Interiors are frequently still open to renovation.

What It Means: 

 The whole neighbourhood's character is protected, not just one building. 

Renovation Implications: 

 Work visible from the street is reviewed against district guidelines. Rear and interior work usually has more freedom. 

What It Means: 

 Ornate detailing, steep roofs, bay windows, decorative trim, narrow deep lots. 

Renovation Implications: 

 Often original plaster, lath, and intricate millwork worth preserving or replicating. 

What It Means: 

Simpler, squarer, larger rooms, red brick, generous front porches. 

Renovation Implications: 

Solid construction; common needs are systems upgrades and opening up compartmentalized layouts.

Direct answer: A "century home" describes a house about 100+ years old, while "heritage" refers to a legal recognition under the Ontario Heritage Act. Most Toronto older homes are century homes without a heritage designation—meaning you have considerable freedom to renovate. Oriel helps you confirm your home's status before you plan. 

Renovation Services We Offer for Older Toronto Homes

Toronto Victorian Home Renovations
Victorian Home Renovations

A Victorian home renovation in Toronto calls for a careful hand, because these are some of the most characterful—and most complex—houses in the city. Decorative plaster, original trim profiles, narrow staircases, and additions layered on over a century all need thoughtful attention. We restore and replicate the details worth keeping while quietly modernizing everything behind the walls. 

Toronto Edwardian home renovations
Edwardian Home Renovations

An Edwardian home renovation in Toronto rewards the effort, thanks to the larger rooms and solid brick construction these homes give us to work with. The most common requests we hear: open up the main floor, modernize the kitchen and bathrooms, and bring the wiring, plumbing, and insulation up to current standards—without losing the porch, the proportions, or the warmth. 

Toronto century home renovations
Century Home Renovations

A century home renovation in Toronto is our bread and butter—the 100-year-old semi is the backbone of neighbourhoods like Roncesvalles, Parkdale, Leslieville, and Bloor West Village. We've renovated dozens of them, gutting and rebuilding floors, underpinning basements, and reworking awkward, wall-heavy layouts into bright, connected living spaces. 

Toronto Historic Home Renovations
Historic Home Renovations

A historic home renovation in Toronto is about extending a building's life, not erasing its past, and that balance is exactly what we've practised since 1973. From masonry and original windows to plaster and stained glass, we preserve the features that give a historic home its value while integrating the structure, insulation, and systems a modern household needs. 

Toronto bay and gable home renovations
Bay-and-Gable Home Renovations

A bay-and-gable home renovation in Toronto is renovation work on the city's most iconic older house style—the tall front bay window crowned by a steep gable that defines streets across Parkdale, Cabbagetown, Trinity-Bellwoods, Little Italy, and Roncesvalles. These narrow, deep Victorian-era homes were built to a standard pattern, and we know their quirks intimately: maximizing the light those big bay windows were designed to capture, opening up the long floor plan, and restoring the ornate rooflines and trim that make them unmistakably Toronto. 

Toronto Georgian Revival Home Renovations
Georgian Revival Home Renovations

A Georgian home renovation in Toronto means working with symmetry, formal proportions, and the quiet dignity these brick-and-stone homes are known for, common in established neighbourhoods like Rosedale, Forest Hill, Lawrence Park, The Kingsway, and Leaside. We respect the balanced façades, centred entries, and refined detailing while modernizing the interiors and systems for how families actually live today. 

Toronto Tudor Revival Home Renovation
Tudor Revival Home Renovations

A Tudor Revival home renovation in Toronto calls for an eye for craftsmanship, given the half-timbering, leaded windows, steep multi-gable roofs, and stone or stucco façades that give these homes their storybook character, found in Old Mill, Forest Hill, Rosedale, and Baby Point. We restore and replicate that distinctive exterior detailing while bringing comfort, efficiency, and modern function to the rooms behind it. 

Toronto Heritage Home Renovations
Heritage Home Renovations

A heritage home renovation in Toronto adds a layer of planning on top of the building work, and we manage both. When a home is heritage-designated or sits in a Conservation District, we coordinate with heritage consultants and architects, prepare the documentation the City needs, and sequence the work to protect the features that are legally and historically significant. We also renovate distinctive local styles such as the grand, eclectic Annex-style homes of the Annex and Yorkville, where Romanesque and Queen Anne influences call for specialized care. 

Explore Our Older & Historic Home Renovation Services

Older homes ask for more than cosmetic updates—they need structure, systems, and original character handled together by one experienced team. Across more than five decades of work on Toronto's century and historic homes, these are the services homeowners rely on us for most.

Westminster Toronto Multi-Unit Renovation Built In Shelving and Fireplace in Sitting Room-2-1

Whole-Home & Single-Floor Renovations

The most valuable thing we do for an older home is reimagine how it lives. We gut and rebuild full interiors or single floors, opening up the awkward, wall-heavy layouts common in century homes into bright, connected spaces—while keeping the character that makes them worth saving. 

Toronto Structural Reinforcement and Home Foundation Work

Structural Reinforcement & Foundation Work

Century homes settle, and their framing and foundations were built to standards a hundred years old. We reinforce floors and ceilings, install beams to open up load-bearing walls, and bring in the right engineers to keep everything safe and code-compliant. 

Toronto Basement Underpinning and Lowering

Basement Underpinning & Lowering

One of the highest-value upgrades for an older Toronto home is gaining real headroom and livable space below grade. We underpin foundations to lower basements, creating the height for finished living areas, in-law suites, or legal secondary suites. 

Toronto Masonry, Facade, and Exterior Restoration and Renovation

Masonry, Façade & Exterior Restoration

A home's street presence is its character. We restore brick and masonry, repair and rebuild porches, and protect the exterior detailing that defines Victorian and Edwardian homes—so the front of your home looks right for its era. 

Toronto Century Custom Millwork

Custom Millwork, Trim & Plaster Replication

The details are what separate a good older-home renovation from a great one. Working with skilled local trades, we restore or replicate original trim, mouldings, panelling, staircases, railings, and plaster so new work is seamless with old. 
Westminster Toronto Multi-Unit Renovation Kitchen with Large Window and Natural Light

Kitchen & Bathroom Renovations

The kitchen and bathrooms are where older homes feel their age most. We design and build kitchens and spa-like bathrooms that work for modern life while respecting the proportions and style of the home around them. 
Toronto Home Systems, Insulation, and Energy Upgrades

Systems, Insulation & Energy Upgrades

Behind every great older-home renovation is invisible work: rewiring knob-and-tube, replacing undersized plumbing, upgrading HVAC, and adding insulation and efficient windows. We route it all thoughtfully so comfort improves and the intervention disappears. 
Toronto Additions & Home Extensions to Older Homes

Additions & Home Extensions

When a home needs more space, a well-designed addition respects the scale and massing of the original house. We add square footage, sunrooms, and expanded living spaces that complement—rather than compete with—the home's historic character. 

What's Different About Renovating an Older Home

Renovating a century home in Toronto is a different discipline from working on a newer property. Here's what experienced older-home renovation actually involves—and how we manage each of it.

Hidden conditions behind the walls

Knob-and-tube wiring, undersized plumbing, old insulation (sometimes none), and concealed water or structural damage are common. Our pre-construction process includes careful exploratory work before pricing is locked in, so surprises become plans instead of panic.

Structure that wasn't built to today's standards

Balloon framing, rubble or brick foundations, and undersized joists are normal in homes this age. We bring in the right engineers and trades to reinforce and underpin properly—especially important when you're opening up walls or finishing a basement.

Details worth saving

Original trim, mouldings, plaster, stained glass, and staircases give these homes their value. Where it makes sense, we restore them. Where pieces are missing or beyond saving, we work with local millwork shops to replicate the profiles so old and new are seamless.

Modern systems, invisibly integrated

Insulation, HVAC, electrical, and energy upgrades have to be routed thoughtfully through a structure that wasn't designed for them. Done well, the comfort is obvious and the intervention is invisible.

Permits, heritage rules, and tight lots

Downtown older homes come with narrow streets, tight parking, close neighbours, and sometimes heritage review. We handle the permitting and the logistics, and we treat your neighbours and your block with respect throughout.

Direct answer: The biggest differences when renovating an older Toronto home are hidden conditions (old wiring, plumbing, and structure), the need to preserve original detailing, and integrating modern systems into a structure that wasn't built for them. A thorough pre-construction process is the single most important thing that keeps these projects on budget and on time.

"He gave his professional opinion as we evolved the project from finishing the basement to underpinning the foundation and building a basement apartment... He was very good at working with us to understand the tradeoffs in an objective manner." — Minora & Christoph, West Bend (100-year-old home)

Meg Riley Product Designer, Google

 "We had been living in our 3-storey semi-detached house for 15 years and had slowly renovated the 100+ year old home one room at a time... The renovation looks exactly like the designs, uncannily so." — Shanna & Kevin, Corso Italia

A note on these numbers: all figures are pre-tax, construction-related costs. Remember to budget an additional 13% HST, plus any temporary accommodations during construction, and a contingency for the unexpected site conditions older homes can reveal. Our pre-construction planning process is designed to surface those surprises early so they become line items, not overruns.

Why older and historic homes can cost more: investigative work up front, more frequent structural and foundation upgrades, careful (slower) demolition to protect original fabric, custom reproduction of millwork and details, and—if designated—added documentation and approvals. We price transparently with fixed-cost estimates, so there are no surprises at the end.

Direct answer: A century or older home renovation in Toronto typically runs from about $50,000 for a partial floor upgrade to $200,000–$400,000+ for a single floor and $500,000–$1,500,000+ for a whole home (pre-tax). Basement underpinning runs roughly $250,000–$400,000+. Historic and heritage-designated properties generally cost more due to investigative work, structural upgrades, and detailed craftsmanship.

Frequently Asked Questions About Century & Older Home Renovations in Toronto

What qualifies as a heritage or historic home in Toronto?

A heritage home can be officially designated under the Ontario Heritage Act (legally protected), listed on the City's Heritage Register (recognized but with limited control), or located within a Heritage Conservation District (where the neighbourhood's character is protected). Separately, Toronto has thousands of century homes—roughly 100+ years old—that carry no official designation but are built like heritage properties: original masonry, hand-built framing, plaster, and historic millwork. These need the same expertise even without a legal designation. 

Can I renovate a heritage home in Toronto, or are there too many restrictions?

You can. Heritage renovation is often encouraged because it extends the life of the building. Restrictions usually focus on elements visible from the street—façades, rooflines, and window patterns. Within those limits there's considerable room to upgrade structure and systems, improve energy performance, reconfigure interiors, and even add space. 

Can I add an addition to a century or heritage home?

In most cases, yes. Additions are possible on older and heritage homes when they're designed to respect the scale and massing of the original house and use complementary materials. Designated and Conservation District properties require more design work and a more detailed submission, but a well-conceived addition can dramatically improve function while keeping the home's character intact. 

Can Oriel match or replicate original trim, millwork, and mouldings?

Yes. Replicating original detail is one of the most rewarding parts of older-home work. Working with local millwork shops and skilled trades, we match historic trim and casing profiles, recreate panelling and built-ins, and integrate new elements that align with the home's original architectural language. 

Why does renovating an older home cost more than a newer one?

Older homes need investigative work up front, more frequent structural and foundation upgrades, careful (and slower) demolition to protect original materials, and custom reproduction of details. Designated properties add documentation and approval costs. The upside: a thorough pre-construction process turns most of these unknowns into a clear, priced plan. 

What unexpected issues come up in century homes, and how does Oriel handle them?

Common surprises include concealed structural deficiencies, knob-and-tube or unsafe wiring, undersized plumbing, hidden water damage, and past renovations that don't meet current code. We manage this with thorough pre-construction planning and phased exploratory work, so we uncover likely issues before final pricing. When something does come up, we present clear options with cost and schedule implications—no surprises at the end. 

Can I live in my home during an older-home renovation?

 Sometimes—it depends entirely on the scope. Smaller, contained projects often allow it; major or whole-home renovations usually mean relocating for safety and speed. We'll walk you through the realistic options for your specific project. (We cover this in depth in our guide: "Can I Live in My Home During a Toronto Renovation or Addition?") 

Do I need a heritage permit for my renovation?

 Only if your home is heritage-designated and the work affects a protected feature, or if you're in a Conservation District and the work is visible from the street. Many older Toronto homes are not designated at all. We help you confirm your home's status early so you know exactly what's required.
