Why Window Paint Fails across Greater Sydney
Window frames are among the most vulnerable architectural elements of any building envelope. Because windows sit at the intersection between glass panes, timber framing, and surrounding brick or rendered walls, they bear the brunt of Sydney’s harsh coastal microclimate.

[Complete Window Paint & Seal Failure]
1. Solar UV Radiation & Thermal Movement
In Sydney, north and west-facing window frames endure high solar exposure. As timber frames expand and contract with temperature swings, rigid or low-grade paints crack along the joints, breaking the protective weather seal and allowing moisture behind the paint film.
2. Moisture Trapped Behind Glazing Putty
On classic double-hung timber sash windows, aging linseed oil putty dries out and shrinks over time. Rainwater running down the glass pools directly behind cracked putty lines, soaking into the end-grain of the timber. This causes wood fibers to swell, rot, and push paint off the frame in thick flakes.
3. Coastal Salt Air Acceleration
In coastal suburbs like Bondi, Bronte, Coogee, and Manly, airborne salt penetrates micro-cracks in exterior paint. Salt retains moisture, accelerating timber rot and rusting any embedded steel fasteners, window hinges, or hardware.
How Easipoint Integrates Window Waterproofing with Painting Services
Applying new paint over leaking window sills or damaged masonry surrounds will only lead to premature paint failure. As licensed remedial builders, Easipoint provides an integrated window waterproofing and painting service in Sydney that seals your building envelope while delivering a refined visual finish.

Perimeter Window Joint Resealing
Perimeter gaps between window frames and surrounding masonry walls are a primary source of internal wall dampness. Prior to applying paint topcoats, our team removes degraded silicone, cleans perimeter joints, installs backing rods, and applies commercial-grade polyurethane (PU) waterproof sealants compliant with AS 4654.
Sub-Sill Waterproofing & Flashing Inspection
When window sills leak into cavity brickwork, simply painting the face does not address the underlying issue. We inspect sub-sill flashings, seal exposed masonry reveals beneath the timber frame, and apply liquid waterproof membranes to ensure rainwater drains away from internal linings.
Our Step-by-Step Window Painting & Prep Process
We execute every window painting project in accordance with AS/NZS 2311 (Guide to the Painting of Buildings) and strict Australian trade standards:

[Step 4: Precision Topcoat Application] ◄── [Step 3: Perimeter Sealing & Priming]
Step 1: Surface Diagnostics, Masking & Glass Protection
We inspect glass seals, sash cords, spiral balances, and timber frame sound. Windows are masked off using heavy-duty glass protection tape, and window catches or locks are protected or removed to ensure clean paint lines.
Step 2: Timber Repair & Surface Preparation
Proper preparation is the foundation of long-lasting window paintwork:
- Scraping & Sanding: All loose, flaking, or bubbled paint layers are scraped back to a firm edge and sanded smooth.
- Timber Rot Treatment: Soft, decayed timber sections are gouged out, treated with timber hardener, and re-profiled using marine-grade, two-part architectural epoxy resins.
- Glazing Putty Re-pointing: Cracked or missing linseed oil putty around glass panes is raked out and re-pointed with fresh glazing compound.
Step 3: Perimeter Sealing & High-Adhesion Priming
We apply targeted primers engineered for timber protection:
- Penetrating Alkyd / Oil-Based Primers for exposed timber end-grains and raw wood.
- Stain-Blocking Primers to prevent tannin bleeding on timber frames.
- Polyurethane Caulking along exterior frame perimeter joints.
Step 4: Precision Topcoat Application
We apply two generous finish coats using premium low-VOC exterior acrylic or traditional enamel paints (such as Dulux Weathershield). Sashes and frames are painted meticulously to ensure smooth operation without sealing the window shut.
Window Frame Condition & Painting Diagnostics Matrix
| Surface Warning Sign | Underlying Cause | Easipoint Remedial & Painting Solution |
| Peeling / Flaking Paint on Sills | UV breakdown, trapped end-grain moisture, lack of primer | Mechanical scraping, timber drying, oil-based primer & 2-coat enamel finish |
| Cracked Glazing Putty | Sun exposure drying out linseed oils over time | Rake out old putty, apply fresh glazing compound & seal with oil-based paint |
| Soft / Rotting Timber Corners | Water pooling at the base of the frame or sub-sill gap | Gouge out rot, apply timber hardener, rebuild with 2-part epoxy resin & paint |
| Gaps Between Frame & Brickwork | Building settlement or drying/shrinking sealant | Rake out old gap filler, install backing rod & inject polyurethane waterproof sealant |
What Sets Easipoint Apart as Your Sydney Window Paint Contractor?
Class 2 Licensed Remedial Builders (Licence 186400C)
Standard painters are often restricted when working on multi-storey properties or structural components. Easipoint operates as a fully licensed Class 2 Building Company under the NSW Design and Building Practitioners (D&BP) Act. We are legally qualified to coordinate scaffolding, high-reach access, and structural repairs for residential homes and strata complexes.
Integrated Joinery & Timber Repair
When we find rotted timber sashes or damaged glazing beads during surface preparation, we don’t halt the job or require you to hire a separate carpenter. Our team performs integrated timber repairs, re-puttying, and balance adjustments under one single contract.
Guaranteed Compliance & HBCF Insurance
For residential and strata repainting projects valued at over $20,000 (incl. GST), we provide mandatory Home Building Compensation Fund (HBCF) insurance certificates, protecting property owners against incomplete work or structural defects.
Window Painting Sydney: Estimated Cost Guide
Window painting costs depend on the number of windows, frame accessibility (ground level vs. upper-storey ladder or scaffolding), and the amount of timber repair or putty replacement required.
| Window Scope & Style | Estimated Cost Range (AUD, incl. GST) | Key Cost Factors |
| Standard Timber Window (Internal & External) | $350 – $700 per window | Frame size, glass pane configuration, preparation level |
| Heritage Timber Sash Window (Heavy Prep/Repair) | $650 – $1,200 per window | Re-puttying glazing lines, timber epoxy rebuilding, lead paint safety |
| Multi-Storey Strata Window Painting | $10,000 – $45,000+ (Project Scope) | Scaffolding/elevated access, Class 2 compliance, perimeter sealing |
Note: Restoring and repainting original timber windows preserves the period character and resale value of your property at a fraction of the cost of full window replacement.
Frequently Asked Questions
How do you keep timber double-hung sash windows from sticking shut after painting?
Sticking sashes occur when paint is applied too thickly inside the pulley tracks or when windows are closed before the paint cures. We paint sashes in stages, clear excess paint build-up from runner tracks, apply lubricating wax to friction points, and ensure coats are fully dry before closing the window.
What process is followed if window frames contain lead-based paint?
Homes built in Sydney prior to 1970 often have lead paint layers on original timber windows. As licensed builders, we test paint layers using chemical spot kits. If lead is present, we follow strict containment guidelines under AS 4361.2 (Guide to Lead Paint Management) using HEPA-filtered vacuum sanding tools to ensure safety.
Do you paint both the inside and outside of timber windows?
Yes. We offer complete interior and exterior window painting. For exterior timber, we use flexible, UV-resistant acrylic or enamel paints that expand with weather changes. For interiors, we apply durable, easy-to-clean enamel finishes.
Why is glazing putty maintenance important before painting?
Glazing putty holds the glass pane securely within the timber frame and prevents rainwater from entering the window joint. If paint is applied over cracked putty, water will seep behind it and rot the timber from the inside. Re-puttying before painting creates an airtight, waterproof seal.
