What to Fix Before Listing Your Home in Ontario

This article is part of our complete guide to selling a home in Ontario. It covers what to fix before listing, what to skip, and what to disclose.

What Should You Fix Before Listing a Home in Ontario?

Start with anything that signals neglect or could stall a deal. These are the repairs that lose buyers at showings, invite lower offers, or surface in the buyer’s inspection. So when you’re deciding what to fix before listing, deal with these first. For what drives buyer decisions more broadly, see our article on what sells homes in the GTA right now.

Water Damage and Moisture

Water stains on ceilings, walls or basement floors worry buyers more than almost any other visible defect. They don’t see a past leak; they see a possible ongoing problem. First fix the source and confirm the area is dry. Then repair and repaint the affected surfaces, and keep the invoices, since the history may need to be disclosed.

Plumbing and Drainage

Dripping taps, running toilets and leaks under sinks are usually inexpensive to fix. A slow drain can be simple or a sign of something bigger, so have it investigated. Together, though, they tell buyers the home hasn’t been maintained, and that impression follows them from room to room. A buyer’s inspector will also list every one of them, which gives the buyer room to negotiate.

Kitec Plumbing in Homes Built Around 1995 to 2007

Kitec is a plumbing system installed in many homes and condos built or renovated between about 1995 and 2007. The pipe is typically orange for hot water and blue for cold. It may be marked Kitec, PlumbBetter, IPEX AQUA or another brand name, and visible fittings may be stamped “Kitec” or “KTC.” Look near the water heater, in the mechanical room and under sinks and vanities. The class action settlement closed to claims on January 9, 2020. If your home has Kitec, get a plumber’s assessment and check with your insurer. In a condo, also check with the corporation who is responsible for which pipes. Then ask your lawyer and Realtor® how to disclose it.

Electrical Red Flags

Test every switch and outlet before listing, and have anything that doesn’t work, flickers or feels warm checked by a licensed electrician. Your panel should be labelled and easy to reach. Older wiring, such as knob-and-tube or aluminum, can affect a buyer’s insurance and financing. So it’s better to know what you have before a buyer’s inspector finds it.

Quick Fixes Before Listing: Doors, Windows and Locks

A door that sticks or a lock that takes effort changes how a buyer thinks. It shifts them from “this is a home I want” to “what else is wrong here?” These are usually quick fixes, and their effect on a showing is out of proportion to the effort. So address them before the first showing rather than after the feedback arrives.

Smoke and Carbon Monoxide Alarms

Every home in Ontario must have a working smoke alarm on every storey and outside all sleeping areas. Carbon monoxide alarms are required outside sleeping areas in homes with a fuel-burning appliance, a fireplace or an attached garage. Since January 1, 2026, they’re also required on every storey, and the rules now cover homes heated by air from a fuel-burning appliance outside the home. Apartments and condo units have their own rules, so check Ontario’s carbon monoxide requirements. Test every alarm and replace expired units before listing.

Deep Cleaning, Decluttering and Odour

Before any paint or repair, deep-clean and declutter. It’s the least expensive preparation and often the most effective. Clear counters and half-empty closets make rooms look larger in photos and in person. Odours matter just as much: pet, smoke and cooking smells register the moment a buyer walks in. Address the source and air the home out rather than covering smells with heavy fragrance, which buyers read as a cover-up.

Should You Fix the Roof and Major Systems Before Listing?

Not automatically. An old roof or furnace that still works doesn’t require replacement just because of its age. Instead, have suspected problems assessed, and separate active defects from age alone. Then compare the cost of repair or replacement with pricing the home for its condition. Our page on what your home is worth can help you see where that lands.

The same applies to the furnace, air conditioning and water heater. Know their age and condition before you list, so you decide how to handle them rather than reacting in the middle of a deal.

Check for Open Building Permits

Past work may have left an open building permit: one that was issued but never closed with a final municipal inspection. These come up in the buyer’s lawyer’s searches and can delay or complicate a closing. If you’ve finished a basement, built a deck or renovated, confirm with your municipality that the permits were closed. Arranging the final inspection before listing is far easier than dealing with it once a deal is in place.

What Should You Disclose After Fixing a Problem Before Listing?

Repairing a problem doesn’t automatically end the need to talk about it. In Ontario, a seller must disclose latent defects: problems a reasonable inspection wouldn’t reveal that make a property unfit for habitation, dangerous or potentially dangerous. The Real Estate Council of Ontario also warns that a seller who tries to hide or cover up a defect faces additional liability.

So when you’re working out what to fix before listing, keep records of what was wrong and what was done. Then ask your real estate lawyer and Realtor® what should be disclosed and how. The law here is complicated, and RECO advises getting a legal opinion when there’s any doubt.

Which Cosmetic Fixes Are Worth Doing Before Listing?

After the functional repairs, a few cosmetic items usually make the biggest difference in how a home photographs and shows. None of them involve renovation, and most don’t need a permit. Staging then finishes what the repairs start; our article on whether professional home staging is worth it explains how the two work together.

Fresh Neutral Paint

Fresh paint in a soft neutral is usually the best-value item on any list of what to fix before listing. Warm white, greige and light grey make rooms look larger in photos and give buyers a neutral backdrop. Bold colours and dark feature walls distract buyers and make spaces look smaller online. Get quotes early, and finish before the listing photographer arrives.

Floors and Lighting

Worn hardwood is one of the first things buyers mention after a showing, and refinishing usually costs far less than replacing. Have carpets professionally cleaned, or replace them if the staining won’t come out. Meanwhile, swap dated fixtures for simple current ones, replace dead or mismatched bulbs, and open blinds before showings so rooms read as bright and cared for.

Bathrooms and Curb Appeal

A bathroom doesn’t need a renovation to show well. Instead, re-caulk the tub and vanity, re-grout where cleaning won’t help, and update a dated light fixture or mirror. Outside, buyers form a first impression before they reach the door. Repaint or clean the front door, edge the garden beds, power-wash the walkway and repair visibly damaged fencing.

What Should You Not Fix Before Listing?

Full kitchen renovations, bathroom gut jobs, additions and structural changes need their own cost-and-return assessment before a sale. Buyers bring their own taste, the work takes time, and the market can change while it’s under way. For a dated kitchen, painting the cabinets, replacing hardware and updating lighting usually captures much of the visual improvement for a fraction of the cost.

Many sellers also renovate because they’ve stopped noticing what buyers notice. The goal isn’t to create your dream home; it’s to remove the distractions that stop buyers seeing the home’s value. Weighing a bigger decision, such as renovating, selling as-is or adjusting your price instead? Our post on whether to renovate before selling walks through that choice.

When a Renovation Doesn’t Pay Off

Is a Pre-Listing Inspection Worth It in Ontario?

For many sellers, yes. A pre-listing inspection can identify accessible defects and help you anticipate buyers’ questions, on your own timeline. It cannot guarantee what another inspector will find. Under the Canadian Association of Home and Property Inspectors’ standards of practice, an inspector visually examines the readily accessible structure and the electrical, plumbing, heating and cooling systems. A standard inspection generally doesn’t involve opening walls or other concealed areas, so hidden defects may remain undetected.

With the report in hand, you can decide which issues to repair and how to reflect the rest in your price, while disclosing what you’re required to disclose. Those options can work together. A price adjustment doesn’t replace a disclosure obligation. Either way, it beats discovering a problem during the buyer’s conditional period, when the price already assumes there isn’t one. Sharing the report with buyers can also reduce uncertainty, which may lead to cleaner offers. Inspection fees vary with the size and age of the home, so get a couple of quotes. For pricing that works alongside these decisions, see our article on choosing the right pricing strategy.

This article is general information, not legal, insurance or construction advice. Repair costs vary by contractor, property and scope, so get written quotes. Disclosure obligations depend on the defect and the law; speak with an Ontario real estate lawyer about what to disclose, and confirm alarm requirements with your local fire department.
