Key Takeaways
- Start with inspection, not finishes. Check structure, water control, safety systems, and hidden risks first.
- Follow a clear priority order: safety and active leaks first, then the building envelope, mechanical systems, layout, and finishes.
- Saskatoon’s freeze-thaw cycles, snow, runoff, and dry winter air make drainage, insulation, and air sealing practical priorities.
- Use qualified professionals for structural, electrical, plumbing, gas, and hazardous-material concerns, and confirm required permits and inspections.
- Build in a project-specific contingency so hidden conditions can be handled without disrupting the whole renovation plan.
Renovating an older home in Saskatoon is not just a matter of choosing new flooring, cabinets, or paint. The important work often happens behind the walls and beneath the finishes.
Before developing renovation ideas or comparing home remodeling ideas, inspect the systems that keep the house dry, warm, stable, and safe. That is the practical answer to how to renovate old buildings: understand the existing structure first, then improve it in a controlled sequence.
Older houses can have solid character and durable materials. They can also contain several generations of repairs, additions, wiring, plumbing, and insulation. Saskatchewan winters expose weak points quickly. Snow loads, freeze-thaw cycles, spring runoff, dry winter air, and shifting temperatures all test a home’s structure and building envelope.

Start with an Inspection-First Plan
Begin with a room-by-room and system-by-system walk-through. Take photographs, record approximate ages, and note anything stained, cracked, loose, drafty, damp, or repeatedly repaired.
A simple planning method from Habitat Saskatoon’s home maintenance guide is to treat the home as a group of aging systems rather than a list of random projects. Record:
- What needs attention.
- Why it matters now.
- Whether it is urgent, seasonal, or a longer-term project.
- Whether it requires a specialist.
- Whether it may affect other work.
This prevents a common mistake: installing new finishes before solving the leak, wiring concern, or insulation gap underneath them.
Prioritized Old Home Inspection Checklist
The table below separates what homeowners can usually observe from what should be assessed by a qualified professional.
| Priority | Area to inspect | Homeowner observations | Professional follow-up |
|---|---|---|---|
| 1 | Safety and active water problems | Gas odour, burning smell, missing alarms, standing water, active leaks, unsafe stairs, loose railings | Emergency services or licensed electrical, gas, plumbing, structural, or water-management professional |
| 2 | Foundation and structure | Step cracks, horizontal cracks, bowing walls, sloping floors, sticking doors, sagging beams | Structural assessment or engineer where movement, settlement, or load changes are suspected |
| 3 | Roof and exterior envelope | Missing shingles, damaged flashing, sagging roof lines, ice-dam staining, cracked masonry, failed caulking | Roofing or building-envelope inspection |
| 4 | Electrical system | Two-prong outlets, overloaded power bars, flickering lights, old panel, visible knob-and-tube wiring | Licensed electrical contractor and TSASK guidance |
| 5 | Plumbing and drainage | Slow drains, low pressure, corroded pipes, staining under sinks, old shutoff valves | Licensed plumber; confirm plumbing permit requirements |
| 6 | Insulation and air sealing | Cold rooms, drafts, frost or condensation, uneven temperatures, high winter heating demand | Energy or building-envelope assessment before adding insulation |
| 7 | HVAC and ventilation | Old furnace, blocked vents, poor bathroom exhaust, window condensation, stale basement air | HVAC professional to assess combustion, ducting, ventilation, and equipment |
| 8 | Hazardous materials | Suspect materials in flooring, pipe insulation, ceiling texture, paint, or older finishes | Qualified hazardous-materials assessor before disturbance or removal |
| 9 | Layout and heritage character | Dark rooms, poor circulation, limited storage, original trim, doors, floors, or masonry | Designer, contractor, or heritage specialist depending on scope |
Foundation, Structure, and Basement Moisture
Look for cracks inside and outside the foundation. Pay attention to cracks that widen, run horizontally, appear in a stair-step pattern, or occur with bowing, uneven floors, or doors that suddenly stick.
In the basement, check for:
- Damp or musty odours.
- Efflorescence, which is a white mineral deposit left by moisture.
- Peeling paint or damaged drywall.
- Wet insulation or mould-like staining.
- Water around floor drains, windows, or utility penetrations.
- Sump-pump operation and discharge location.
A visual inspection can identify clues, but it cannot confirm whether movement is active or whether a foundation can support a new opening, beam, addition, or basement alteration. Get qualified advice before removing walls or changing loads.
Water control comes first. A new basement finish will not solve a drainage problem.
Roof, Grading, and Drainage
Inspect the roof covering, valleys, flashing, chimneys, soffits, fascia, and attic for signs of water entry. Saskatoon snow and temperature swings can expose weak flashing and create ice dams. An ice dam forms when melting snow refreezes at a colder roof edge, potentially directing water beneath the roofing.
Outside, check whether soil slopes away from the foundation. Look for low spots where snowmelt or rain collects. Confirm that eavestroughs are clear and downspouts discharge well away from the foundation rather than beside it.
These are visible checks. Roof framing, hidden flashing, foundation drainage, weeping tile, and waterproofing require a professional assessment when concerns appear.
Electrical Systems, Including Knob-and-Tube Wiring
Older homes may contain knob-and-tube wiring, older panels, ungrounded outlets, or circuits that were not designed for modern appliances and equipment. Do not remove insulation around wiring, make connections, or assume that a working system is a safe system.
A homeowner can photograph the electrical panel and visible wiring and note tripped breakers, warm outlets, flickering lights, or damaged cords. A licensed electrical professional should assess the system, especially before opening walls or adding circuits.
Electrical permits and inspections are administered through the Technical Safety Authority of Saskatchewan. Confirm the current process before work begins.
Plumbing, Supply Lines, and Drainage
Identify visible pipe materials and look for corrosion, leaks, low water pressure, slow drains, and repeated repairs. Older homes may have galvanized supply lines or other outdated materials. Some homes may also have older drain lines or service connections that need investigation.
Do not rely on a fixture upgrade to solve a deteriorating plumbing system. A plumber can assess supply lines, drain-waste-vent piping, shutoffs, sewer connections, sump discharge, and backwater protection.
The City of Saskatoon states that plumbing systems cannot be constructed, extended, altered, renewed, or repaired without a plumbing permit. Verify current requirements before starting.
Insulation, Air Sealing, Windows, and Doors
Cold rooms do not always mean the furnace is too small. Heat loss may come from incomplete insulation, air leakage, poorly sealed rim joists, gaps around windows, or an interrupted vapour barrier.
A vapour barrier helps limit moisture movement into insulated assemblies. Air sealing stops uncontrolled drafts through joints, penetrations, and gaps. Both need to be considered with ventilation. Sealing a house without addressing required fresh-air exchange can create new moisture and indoor-air concerns.
Inspect:
- Attic insulation depth and gaps.
- Insulation around basement rim joists.
- Drafts at window and door frames.
- Condensation or frost on windows.
- Damaged weatherstripping and caulking.
- Uneven temperatures between rooms.
Before adding insulation, determine what is already present and whether moisture is entering the assembly. The wrong retrofit can hide a problem rather than correct it.
HVAC, Ventilation, Fire Safety, and Hazardous Materials
Have the furnace, boiler, water heater, chimney, and ductwork assessed before changing the layout. Confirm that bathroom fans exhaust outdoors, kitchen ventilation is appropriate for the equipment, and exterior vents are clear.
Check smoke and carbon monoxide alarms, bedroom egress, stair guards, handrails, and fire separations. These details affect safety and may affect permit requirements.
Older materials should be treated carefully. Asbestos may be present in some older building products, while lead may be present in older paint or dust. Their presence cannot be confirmed by sight alone. Do not sand, cut, scrape, or demolish suspect materials without appropriate assessment.
The City’s renovation guide notes specific asbestos notification requirements for buildings constructed before 1990. Review the current City of Saskatoon renovation project guide before disturbing materials.
Layout, Function, and Heritage Character
Once safety, structure, water, and systems are understood, assess how the home works for daily life. Look at circulation, storage, daylight, mudroom space, kitchen workflow, bathroom access, and basement use.
Good house renovation ideas do not need to erase original character. Preserve sound trim, doors, hardwood, masonry, built-ins, and proportions where practical. Modernize the systems behind them.
The Right Renovation Sequence
A reliable old home renovation usually follows this order:
Safety and hazardous materials
Address electrical, gas, fire-safety, structural, and hazardous-material concerns first.Active water problems
Repair roof leaks, foundation moisture, plumbing leaks, grading, drainage, gutters, and downspouts.Structure and building envelope
Resolve foundation or framing issues, then improve roof performance, windows, doors, insulation, and air sealing.Mechanical systems
Coordinate electrical, plumbing, HVAC, ventilation, and controls before closing walls.Layout and function
Change walls, storage, room flow, kitchens, bathrooms, or basement spaces once the underlying systems are ready.Cosmetic finishes
Install drywall, flooring, cabinets, trim, paint, and fixtures last.
This sequence reduces rework. It also protects the money spent on finishes.
Permits, Professionals, and Budget Contingency
The City of Saskatoon building permits page lists common projects that require permits, including basement development, structural repairs, additions, alterations, some exterior changes, and repairs after fire or water damage. Cosmetic work such as painting or patching drywall may not require a building permit when it is the entire scope.
Permit requirements depend on the project. Plumbing, structural, electrical, and gas work may involve permits, inspections, licensed trades, or separate authorities. Confirm current requirements with the City and TSASK rather than relying on an older rule of thumb.
For budgeting, older homes often contain unknowns behind walls and below floors. A 15–25% contingency may be reasonable for some renovation scopes, particularly where access is limited or systems are outdated. It is not a universal rule. The right allowance depends on the home’s age, condition, drawings, project size, and inspection findings.
For ongoing planning, track maintenance separately from larger capital replacements. This follows the practical approach outlined by Habitat Saskatoon and makes future decisions less reactive.
Questions to Ask Renovation Contractors
Before hiring a contractor, ask:
- What conditions will you inspect before providing a final scope?
- Which parts of this project require licensed trades or permits?
- Who will coordinate City and TSASK inspections?
- How will you protect original trim, floors, masonry, and other heritage details?
- What assumptions are included in the estimate?
- How will hidden conditions and change orders be documented?
- What is the planned sequence, and which decisions must be made before demolition?
- What contingency do you recommend for this specific home, and why?
- How will you manage ventilation, insulation, and moisture as walls are opened?

Frequently Asked Questions
What is the first thing to inspect in an old Saskatoon home?
Start with safety, active water entry, foundation movement, roof condition, and major system concerns. Cosmetic improvements should wait until these risks are understood.
Can I inspect an older home myself?
You can document visible signs such as cracks, stains, drafts, damaged caulking, old wiring, and poor drainage. You should not diagnose structural capacity, electrical safety, plumbing condition, gas equipment, or hazardous materials without qualified help.
Should I replace knob-and-tube wiring before renovating?
Have it assessed before opening walls or adding circuits. A licensed electrical professional can explain the condition, risks, required work, and inspection process for the specific home.
Do old-home renovations in Saskatoon require permits?
Some do and some do not. Basement development, structural changes, additions, and several building alterations commonly require permits. Check the City’s current guidance for your exact scope.
How much contingency should I include?
There is no single correct percentage. For some older-home projects, 15–25% can provide a practical buffer for concealed conditions, but the appropriate amount depends on inspection results and the complexity of the work.
Can I modernize an old home without losing its character?
Yes. Preserve sound original elements and improve the systems behind them. Careful layout planning, compatible materials, and detailed trim work can make the home function better without making it feel generic.
What is the next step before starting an old house renovation?
Create an inspection list, gather available records, confirm permit requirements, and arrange professional assessments for structural, electrical, plumbing, gas, HVAC, and hazardous-material concerns as needed. A clear starting condition gives you better decisions and greater peace of mind.
