The smart upgrade homebuyers notice — and one that could add up to 20% to your sale price.
Why Home Improvements Matter in the Perth Property Market
In a competitive real estate market like Perth’s, first impressions matter, but long-term performance matters even more. Today’s buyers are no longer just looking for polished floors and fresh paint. They’re looking for homes that feel comfortable, stay quiet, and run efficiently.
One upgrade that ticks all those boxes? Double glazed windows.
Post-2020, demand for energy-efficient, well-insulated homes has surged. Buyers are prioritising comfort, liveability, and reduced running costs, and double glazing delivers all three. For sellers, that means stronger buyer appeal, faster sales, and in many cases, a measurable boost in property value.
In this article, we’ll explore:
- Why double glazing is now a standout feature in Perth home listings
- How it compares to other popular home upgrades in terms of ROI
- What local agents are saying about buyer preferences
- Real numbers on cost, return, and market impact
- Which window styles add the most value in WA homes
Whether you’re planning to sell or simply want to future-proof your investment, this guide will show you why upgrading your windows could be the smartest decision you make.
Why Perth Buyers Are Looking for Energy-Efficient Homes
Energy efficiency has shifted from “nice to have” to “must-have”, and it’s not just the eco-conscious driving the trend. In Perth’s property market, buyers are actively looking for homes that perform better, feel better, and cost less to run.
Shifting Buyer Priorities Post-2020 (Comfort, Costs, Noise)
The past few years have redefined what people want from their homes. After spending more time indoors, many Perth homeowners and buyers now prioritise:
- Thermal comfort in both summer and winter
- Lower energy bills in the face of rising costs
- Quieter living environments, especially in growing suburban areas
Double glazed windows help meet all three goals in one move, making them a standout during home inspections.
Local Agent Insights: What Stands Out in Home Inspections
While features like new kitchens and fresh carpet still matter, real estate agents across Perth report that visible performance upgrades, like quality windows and doors, give buyers more confidence in the overall build.
According to agent feedback (paraphrased):
- “Buyers ask whether the home has double glazing almost as often as they ask about the kitchen.”
- “Thermal comfort is a big selling point, especially for families and older buyers.”
- “Homes with double glazing generally feel quieter and more ‘solid’, which translates to perceived value.”
Western Suburbs + Hills Buyer Expectations
In higher-value suburbs like Claremont, Subiaco, Cottesloe, and the Perth Hills, energy efficiency is no longer a bonus, it’s expected. Homes in these areas often attract buyers who are:
- Environmentally aware
- Seeking long-term comfort
- Planning to live in the home rather than flip it
In these markets, double glazed windows are often seen as a sign of quality, and a lack of them may raise questions during negotiation.
How Double Glazed Windows Add Real Property Value
Double glazed windows don’t just improve how a home feels, they also influence how it performs on the market. From perceived quality to practical cost savings, glazing upgrades can directly impact your final sale price and buyer confidence.
Up to 20% Resale Uplift — The Figures Behind It
While results vary by property type and suburb, research from Australian building and valuation experts shows that energy-efficient features like double glazing can add up to 10% to a home’s market value.
Why? Because buyers know they’re getting:
- Long-term savings on heating and cooling
- Improved comfort without needing to renovate
- A home that meets (or exceeds) modern performance standards
In a rising market, that 10% could mean tens of thousands of dollars in added equity, simply by upgrading your windows.
Higher Buyer Trust: Perceived Quality = Higher Offers
Homes with double glazing often feel more “complete.” Windows seal better. Noise drops. Thermal comfort improves. These subtle improvements create a strong sense of build quality, which in turn leads to:
- Higher buyer confidence during walk-throughs
- Stronger initial offers
- Less pushback during price negotiations
For character homes, heritage upgrades, and energy-conscious buyers, double glazing signals that the home has been well looked after, not just cosmetically updated.
Lower Days on Market — How Double Glazing Helps You Sell Faster
In competitive areas, homes that stand out for comfort and efficiency tend to spend less time on the market. Buyers recognise the benefits and act quickly, especially when:
- The home offers a quiet retreat in a busy suburb
- Energy savings align with cost-of-living concerns
- The glazing fits the home’s aesthetic and architectural style
In short: double glazing isn’t just a long-term value play, it can help you sell faster, with fewer concessions and stronger buyer interest.
Comparing Value: Double Glazing vs Other Home Upgrades
When preparing a property for sale, many homeowners prioritise upgrades like new kitchens, flooring, or bathrooms. While those can be effective, double glazing often delivers a better return-on-investment, especially in Perth’s performance-conscious market.
Why Glazing Outperforms Kitchen or Flooring Upgrades (ROI vs Cost)
A full kitchen renovation can cost $25,000–$40,000, and while visually impactful, it’s also taste-sensitive. Buyers may still want to change the colour scheme or layout.
Double glazed windows, by contrast:
- Deliver functional improvements (temperature, noise, bills)
- Aren’t subject to buyer design preferences
- Are perceived as a structural upgrade, not cosmetic
In many cases, glazing offers similar value uplift at a lower overall cost, especially when done strategically across key rooms or street-facing windows.
Lower Energy Bills = Better Cost-of-Living Appeal for Buyers
As power costs continue to rise across WA, buyers are more attuned to the running costs of a home. Double glazed windows can:
- Cut heating/cooling energy use by up to 30%
- Make ducted or split-system air con far more efficient
- Reduce the need for blinds, fans, or constant AC in shoulder seasons
This makes a real difference for families, downsizers, and investors alike, and positions your home as a cost-effective, comfort-first choice.
Security and Peace of Mind as Hidden Value Drivers
Beyond energy, double glazing adds security and soundproofing benefits that buyers don’t always expect, but quickly notice:
- Toughened glass = harder to break
- Multi-point locking systems = stronger deterrent
- Acoustic insulation = less street noise, more privacy
These benefits are hard to put a price tag on, but they absolutely contribute to perceived value and stronger offers.
The Curb Appeal Factor: Modern Frames, Clean Lines
First impressions count, and your windows play a bigger role than most homeowners realise. When potential buyers pull up outside, sleek, modern frames and clean glazing lines immediately signal quality and care.
How Sleek Double Glazed Windows Boost Visual Impact
Old or mismatched windows, especially in aluminium or timber, often show age faster than other building materials. Peeling paint, oxidised frames, and fogged glass all create a tired look.
By contrast, Penot’s thermally broken aluminium frames offer:
- Crisp architectural lines that elevate your facade
- Powder-coated finishes in modern tones to match WA styles
- Glazing clarity that makes interiors feel clean, bright, and private
It’s the difference between “needing work” and “move-in ready.”
Matching Window Types to Architectural Styles (Perth-Specific)
Penot works across every style of Perth home, from Cottesloe beach builds to Mount Lawley character restorations. Popular pairings include:
- Sliding windows for modernist or coastal homes
- Casement or double-hung for Federation or bungalow builds
- Awning styles for contemporary renovations or passive design projects
The right frame shape doesn’t just look good, it also enhances liveability, natural light, and ventilation.
Real-World Case Study: Pre- and Post-Glazing Street Appeal
A recent project in Subiaco replaced weathered timber windows with slimline aluminium casement windows in a heritage-sympathetic tone. The result?
- A sharper street view with better light balance
- A noticeable increase in enquiry at sale time
- Buyers calling out “new windows” as a major selling point
Sometimes, it’s not just what you renovate, it’s what it communicates.
Real Estate Agents Weigh In
What do Perth’s property professionals think about double glazing? The answer is clear: it’s becoming a non-negotiable in high-value suburbs, especially where energy efficiency and acoustic comfort matter most.
Quotes from Local Perth Agents (Paraphrased Insight)
While direct quotes will add power later, here’s a summarised snapshot of what agents consistently tell us:
- “Buyers love seeing new windows — they assume the home has been well maintained.”
- “Double glazing is one of those upgrades people don’t always ask for… until they see it.”
- “In places like Floreat and Dalkeith, it’s now expected in any mid-to-high tier listing.”
It’s not just about looks. It’s about buyer confidence.
What’s Driving Premium Buyer Interest in Thermally Efficient Homes
Modern buyers, especially professionals and young families, are seeking:
- Lower energy bills
- Comfortable temperatures year-round
- Quieter interiors near roads, schools, or coastal wind zones
Double glazing delivers on all three, making it a compelling feature during inspections.
Suburbs Where Double Glazing Is Becoming the Expectation
Penot sees rising demand in suburbs like:
- Cottesloe, Claremont, Subiaco – character homes needing comfort upgrades
- City Beach, Applecross, Mount Pleasant – modern builds demanding high spec glazing
- Gooseberry Hill, Kalamunda – bush-adjacent homes seeking thermal + BAL-rated performance
These aren’t outliers. They’re bellwethers for broader buyer trends across Perth.
How Much Do Double Glazed Windows Cost — and What’s the Return?
Double glazing is more than a comfort upgrade, it’s a value-adding decision that positions your home as modern, efficient, and move-in ready.
Long-Term Value vs Short-Term Cost
While any home improvement comes with upfront costs, double glazing pays back through:
- Lower energy bills from improved thermal insulation
- Enhanced comfort during hot Perth summers and cool winters
- Reduced external noise for a more peaceful living environment
- Fewer maintenance issues compared to ageing single-glazed windows
These benefits don’t just improve day-to-day living, they influence how buyers perceive your home’s overall quality.
When Is the Best Time to Upgrade?
- Before selling: Boosts curb appeal, performance ratings, and buyer confidence during inspections
- During renovations: Ideal for integrating with other façade, interior, or layout changes
- If you’re staying long-term: You enjoy the comfort now, while future-proofing your home’s market value
Double glazing is one of the few upgrades that improves both lifestyle and investment return, whether you’re planning to list soon or not at all.
Which Window Types Add the Most Value?
Not all windows deliver the same impact when it comes to boosting perceived value and buyer appeal. The right choice depends on your home’s layout, style, and the lifestyle benefits buyers are seeking.
Sliding, Stacking, and Awning Styles Stand Out
- Sliding and stacking windows create large, openable sections ideal for Perth’s climate and indoor-outdoor living trends. Their wide, uninterrupted views are a strong selling point.
- Awning windows offer excellent weather protection while allowing ventilation during rain, a practical and stylish choice for many homes.
These configurations strike a balance between design impact and functionality.
High-End and Heritage Buyers Notice the Details
If you’re in a premium or character suburb, details matter:
- Casement and double-hung windows retain the period charm expected in heritage zones like Subiaco or Mount Lawley.
- Minimalist tilt-turn systems suit architectural builds and buyers focused on European-style performance and aesthetics.
Matching window styles to the property’s overall feel enhances the sense of cohesion, and can increase buyer trust.
Glazing That Matches Lifestyle Needs
More buyers are asking about how homes manage:
- Heat gain and UV protection
- Street and aircraft noise
- Natural ventilation and airflow
Choosing double glazing that aligns with these lifestyle needs, and clearly communicating those benefits, adds tangible value in the eyes of discerning buyers.
Planning to Sell or Stay? Either Way, Glazing Is a Smart Move
Whether you’re preparing your home for market or settling in for the next decade, double glazing delivers benefits that go well beyond short-term aesthetics.
Selling in the Next 6–12 Months?
If you’re planning to list soon, new double glazed windows can:
- Differentiate your home from similar properties
- Reduce time on market by signalling energy efficiency and quality
- Add resale appeal in competitive areas like Nedlands, City Beach or South Perth
They also help your home feel cooler, quieter, and more comfortable during open inspections, giving buyers a sensory reason to fall in love.
Staying Long-Term? It Still Pays Off
If you’re not going anywhere for a while, the long-term value is just as strong:
- Lower energy bills through better thermal insulation
- Quieter interiors thanks to improved acoustic control
- A more comfortable living experience, year-round
And should you choose to sell down the track, your home will already have one of the most sought-after upgrades in place.
