10 Questions to Ask Before Buying a Century Home
Century homes have a kind of magic to them.
They offer warmth, craftsmanship, history, and character that newer homes often struggle to match. From original trim and wood floors to deep porches, solid doors, and unique architecture, these homes can feel special the moment you walk in.
At Team Prata Real Estate, we see why so many buyers fall in love with century homes across Trent Hills and Northumberland County. They often sit on beautiful lots, have timeless curb appeal, and give people the feeling that they are buying something with real soul.
But charm is only one part of the equation.
Older homes can also come with hidden costs, aging systems, and restrictions that buyers need to understand before moving forward. If you are thinking about buying a century home, these are the questions worth asking before you commit.
What Counts as a Century Home?
In simple terms, a century home is usually a home that is at least 100 years old.
That can include farmhouses, Victorian homes, brick town properties, classic village homes, and many other architectural styles. What makes these homes so appealing is often the craftsmanship and detail. What makes them more complex is that many were built in a very different era, with different materials, systems, and standards than today’s homes.
That does not make them a bad purchase. It just means they deserve a closer look.
1. What Is the Home’s Maintenance and Renovation History?
This is one of the first questions to ask because it tells you how well the property has been cared for over time.
You want to know what has already been updated and what may still be original. Ask about roofing, plumbing, wiring, windows, insulation, foundation work, drainage improvements, heating systems, and major renovations. A century home that has been maintained thoughtfully is a very different story than one that has simply aged in place.
Receipts, invoices, warranties, and records of past work can be incredibly helpful. They give you a clearer picture of what has been done properly and what may still need attention.
2. Is the Property Heritage Designated or Located in a Heritage District?
This one matters a lot in Ontario.
If a property is individually designated under the Ontario Heritage Act, or located in a heritage conservation district, certain alterations may require approval. Ontario’s guide states that owners of designated properties must obtain written municipal consent for alterations that affect heritage attributes, and municipalities also have authority over certain exterior alterations in heritage conservation districts.
That does not mean you cannot make changes. It means you need to understand what kind of changes may be restricted before you buy. This is especially important if you are planning to replace windows, alter the exterior, change materials, or take on a major renovation.
3. What Does the Inspection Reveal About the Foundation and Structure?
A century home does not need to be perfect, but you do need to know what you are inheriting.
Look closely at the foundation, basement, support beams, visible cracks, moisture issues, and floor levels. Some movement and age related settling can be normal in older homes, but major structural concerns are a different story. Sloping floors, sticking doors, cracks around openings, and signs of water intrusion all deserve careful attention.
A thorough home inspection is one of the most important steps in this process. In older homes, it can uncover issues that are not obvious during a casual showing.
4. What Type of Wiring Is in the Home?
Electrical systems are a major issue in many older properties.
Some century homes may still have outdated wiring or partial upgrades. Even if the house has been improved over the years, you want to know whether the system has been fully modernized or only updated in sections. This affects safety, insurance, and future renovation work.
Ask specifically whether the electrical panel has been updated and whether any older wiring remains. This is one of those details you do not want to leave vague.
5. What Type of Plumbing Is in Place?
Like wiring, plumbing in older homes may have been upgraded, partly upgraded, or left original in certain sections.
Ask what materials are in use, whether supply and drain lines have been replaced, and whether there have been any recurring issues with water pressure, leaks, or drainage. The cost of plumbing updates can add up quickly, especially in homes where access is difficult.
A home that has had thoughtful plumbing improvements over time is much easier to budget around than one with major unknowns hiding behind walls and floors.
6. Are There Any Signs of Moisture, Mould, or Drainage Problems?
Water is one of the biggest threats to any home, and that is especially true in older ones.
Pay attention to musty smells, stains, efflorescence in basements, peeling finishes, visible patchwork, and signs that water has entered the home before. Ask whether the basement has ever leaked, whether sump systems are in place, and how water moves away from the house during heavy rain or snow melt.
A charming old home can still be a smart purchase. But if moisture has been ignored for years, it can turn into a very expensive project.
7. Could There Be Lead Paint, Asbestos, or Other Older Materials to Deal With?
This is a very important question in century homes.
Health Canada says homes built before 1960 likely contain lead based paint, and older building materials may also contain asbestos, especially in products used before 1990 such as insulation, plaster, floor and ceiling tiles, siding, roofing materials, drywall compounds, and pipe insulation. Disturbing these materials during renovations can create health risks, which is why it is important to understand what may be present before you start opening walls or sanding old surfaces.
This does not mean every century home is unsafe. It means you should go in informed and treat renovation planning carefully.
8. What Heating System Is Being Used and How Efficient Is It?
Many older homes have had multiple heating systems over the years.
Ask what is currently heating the home, when it was installed, how efficient it is, and whether there are any maintenance concerns. Also ask about insulation, draftiness, and operating costs. Beautiful old homes can sometimes come with beautiful heating bills too if they have not been upgraded properly.
This is especially important in Ontario, where long winters can expose every weakness in an older home’s envelope.
9. Have the Windows, Doors, Chimney, and Roof Been Updated?
These are major building components that affect comfort, efficiency, and long term cost.
Original windows and doors can be beautiful, but they may also be drafty or in need of restoration. Chimneys should be checked carefully if they are active or have not been used in years. Roof age, flashing, gutters, and exterior drainage all matter too.
Ask not just whether these items have been replaced, but when and by whom. A newer roof and updated windows can change the financial picture of an older home in a big way.
10. Are There Any Grants, Tax Relief Programs, or Local Incentives Available?
This is a smart question to ask, but it is important to stay realistic.
Ontario has a guide for municipalities that choose to offer a heritage property tax relief program, but it is not automatic province wide. Availability depends on the local municipality and the property meeting the program rules.
In other words, some help may exist, but you should never assume it does. If you are buying a century home because you hope grants will offset restoration costs, verify everything early.
Red Flags to Watch for During a Showing
Even before the inspection, there are clues that can tell you a lot.
Watch for uneven floors, doors that do not close properly, water staining, fresh paint in suspicious spots, musty smells, damaged masonry, worn windows, corroded fixtures, sagging rooflines, or signs of neglected maintenance outside. None of these automatically kill the deal, but they are signals to slow down and dig deeper.
Older homes need a little more curiosity from the buyer. That curiosity can save you a lot of money.
Is a Century Home Right for You?
That depends on your lifestyle, budget, and mindset.
If you love character, craftsmanship, and homes that feel different from everything else on the street, a century home can be incredibly rewarding. But if you want very low maintenance, perfect straight lines, modern efficiency, and no surprises, a newer home may be a better fit.
The right buyer for a century home is usually someone who appreciates what makes it special and is prepared for the responsibility that can come with it.
Final Thoughts
