Getting a free double glazing quote in Australia is your first step toward reducing external noise, improving comfort, energy efficiency, and cutting heating and cooling bills. Many homeowners in Australia don’t realise their current single glazed windows or doors are quietly draining their wallets and disrupting their sleep. Smart homeowners in Australia are upgrading to double glazing—are you?
Upgrading to double glazed windows and doors offers:
- Noise reduction by up to 80%
- Lowering heat transfer by up to 70%
- Cutting energy bills by up to 20%
However, not all quotes are created equal. Understanding the process, what should be included, and potential red flags is essential to making the right choice for your home and budget before proceeding with double glazing your windows and doors.
What to Expect During Your Free Double Glazing Consultation
A professional consultation should feel more like an expert assessment than a sales pitch. Your free consultation typically includes:
- Comprehensive evaluation of your existing windows, doors, and building structure to identify external noise sources, heat gain areas, and where heat loss is most significant.
- Discussion of your home’s thermal needs, noise levels, and aesthetic goals.
- Explanation of options like double glazed glass, secondary glazing, and different frame designs, such as aluminium or timber.
- Clarity around noise reduction, energy efficiency performance, and how specific products like argon gas-filled panes of glass can help.
- A clear explanation of what glazing work will be required for your windows or doors.
At the end, you should receive a tailored recommendation—not a generic offer.
3-Step Process:
- Free site assessment (windows, doors, etc.) and consultation
- Receive a detailed written quote with product and installation service breakdown
- Discuss the best options and next steps with no-obligation follow-up
Everything a Good Double Glazing Quote Should Include
A detailed quote should remove confusion, not create it. Look for the following elements in any professional double glazing quote for your windows and doors:
- Product details, including glass type, whether it’s double glazed glass with argon gas or simple air-filled, and frame material like aluminium.
- Specification of double glazed windows or double glazed doors, including size and style (sliding doors, double sliding doors, casement windows, bi-fold windows, awning windows, louvre windows, hinged windows, or fixed windows).
- Installment summary: how work will be done, timelines, and disruption minimisation.
- Thermal and acoustic performance indicators (such as U-values, R-values, or decibel reduction estimates).
- Total inclusive pricing for materials, labour, and any extra services.
- Finance or payment plan options (if available).
- Warranty terms and guarantees on products and fitting.
- Timeline to project start and estimated completion.
If anything is missing or vague, clarify before proceeding.
Double Glazing Costs Breakdown: Materials, Installation & Hidden Extras
Understanding how your quote is structured can prevent surprise charges. Pricing can vary widely depending on your selections, but typical costs include:
Cost Component | Typical Cost Range (AUD) |
Standard window unit | $270 – $900 per window |
Sliding or bi-fold doors | $500 – $2,500+ per door unit |
Argon gas fill upgrade | $30 – $50 extra per unit |
Low-E coating upgrade | $50 – $100 extra per unit |
Installation labour | Often included in quote |
Old window disposal | $50 – $150 (if not included) |
Complex door and window designs, large units, or premium finishes can increase costs. Confirm whether site clean-up, scaffolding, or painting touch-ups are included.
Hidden extras to watch out for:
- Disposal of existing single glazed window units
- Additional site works in heritage or older homes
- Custom frame colour upgrades for windows and doors
- Large or unusually shaped door or window units
While a basic air-filled double glazing solution may seem more cost effective, investing in argon gas-filled panes, low-E glass, and premium frames often delivers better long-term performance and lower energy costs.
Top Questions to Ask Before Buying Double Glazing
Before accepting any quote, ask:
- Is the double glazing argon gas-filled or just air?
- Are Low-E coatings included?
- What acoustic and thermal performance can I expect?
- What frames will be installed? Are they aluminium, timber, or different?
- Are all disposal and fitting costs included?
- What warranty do you offer on the fitting and the product?
- How long will the new installation take, and when can work start?
- Are there finance or payment plans available?
- Who will handle the installation – subcontractors or company employees?
Clear, expert answers help validate that you’re dealing with professional double glazing installers.
Double Glazing Quote Warning Signs: Red Flags to Avoid
Not all companies are transparent. Watch for these red flags:
- Quotes lacking precise product specifications (glass type, gas fill, frame material)
- No clear breakdown of installment methods or timelines
- Verbal-only quotes with no written breakdown
- Overly aggressive sales tactics pushing full house upgrades without assessment
- Unrealistically low prices without explaining differences in materials or workmanship
- Absence of warranty or guarantee details
- Lack of local service history or customer support options
Quotes missing these essentials may indicate low-quality products or unprofessional service.
Double Glazing Warranties: What’s Really Covered?
Warranties can vary significantly between companies. Standard coverage should include:
- 10 to 20-year manufacturer warranty on double glazed glass units
- 5 to 10-year installation workmanship guarantee
- Coverage against condensation between panes, which indicates seal failure
- Frame warranties (aluminium often carries 10-15 years)
Clarify whether warranties are transferable to future home buyers and whether service calls (in case of issues) are included.
Double Glazing Finance Options: Payment Plans & Special Deals
Many double glazing companies in Australia now offer new, flexible payment terms, such as:
- Interest-free payment plans over 6 to 24 months
- Low-interest finance with extended terms
- Seasonal promotions or bundled discounts (e.g. “install before winter” deals)
- Deposit-free installation with repayments over time
Always check terms carefully, including total repayment amounts and any early exit fees.
Finance options can make upgrading to energy-efficient windows and doors more accessible without compromising on quality.
How to Compare Double Glazing Quotes (And Get the Best Price)
When comparing quotes:
- Compare like-for-like: Are all products argon gas-filled? Are frame types consistent?
- Review performance metrics (U-value, noise reduction, warranty period).
- Clarify who will install the units and whether after-sales support is included.
- Look for companies offering a clear contract—not just a verbal promise.
- Don’t focus solely on price; focus on long-term savings, comfort, and product lifespan.
Choosing the cheapest quote without understanding what’s excluded can cost more over time in energy bills and comfort.
Why a Detailed Contract Matters in Double Glazing Projects
A detailed contract protects your investment and should include:
- A comprehensive list of double glazed windows and doors being installed
- Exact product specifications (including coatings, gas fill, frame type)
- Payment terms and schedule
- Project timeline from start to finish
- Warranty details
- Installation method and site management plan
- Policy on handling unforeseen issues or delays
Ensure all verbal promises are documented in the contract before paying any deposit.
Next Steps After Receiving Your Double Glazing Quote
Once you’ve received your detailed quote, your next steps are:
- Review all provided documentation carefully.
- Compare quotes side-by-side based on specifications, not just price.
- Ask any clarifying questions and request adjustments if needed.
- Sign a formal contract that protects your interests.
- Schedule the fitting and prepare your home for the project.
