Window & Door Repairs

Windows and doors are among the most visible and most functional elements of your home. They frame every view, define your home’s character from the street, and are the surfaces guests interact with most directly. When timber window frames rot, doors warp and stick, or paintwork peels and cracks around these critical openings, it affects both the appearance and the performance of your home. At House Painting Sutherland Shire, we specialise in the repair, restoration, and repainting of timber windows and doors across the Sutherland Shire.

Our team brings over 30 years of experience in timber repair and painting to every window and door project. We understand the specific challenges that Sydney’s coastal environment creates for exterior joinery — the way salt air accelerates timber deterioration, how moisture penetrates cracked or poorly maintained paint and causes rot, and how to restore damaged timber frames to sound, paintable condition that will last. Fully licensed (Licence #257400C) and fully insured.

Whether you need a single rotted sill repaired and repainted, all your window frames refreshed, doors rehung and repainted, or a full window and door painting program across your whole home, we deliver quality results efficiently.

Our Window & Door Repair Process

1. Assessment & quote — We inspect every window and door, probe timber for rot, test for adhesion issues, and assess the full scope of repair and repainting required. Clear written quote provided.
2. Timber assessment — Where rot is found, we assess how deep it extends. Superficial rot can often be treated with hardener and epoxy filler. Deep structural rot requires timber replacement.
3. Rot treatment — Affected timber saturated with penetrating epoxy timber hardener to consolidate friable material and kill remaining decay organisms.
4. Epoxy repair or timber replacement — Epoxy filler used to rebuild minor rot damage; replacement timber used for larger structural repairs. New timber treated with preservative before installation.
5. Sanding & preparation — All repaired and surrounding surfaces sanded smooth. Flaking and peeling paint removed. Surfaces prepared for primer.
6. Priming — All bare timber and repaired areas primed with appropriate exterior primer. Critical step — without it, topcoat adhesion fails and rot can recur.
7. Painting — Two topcoats applied in the agreed colour. Cut-in work done carefully around glass, hardware, and adjacent walls.
8. Door adjustments — If doors were sticking, planing and hinge adjustment completed before final paint coat so everything operates smoothly.

Why Window & Door Repairs Matter

Windows and doors are the most vulnerable points in your home’s external envelope. Wherever timber meets external conditions — frame bases, sills, glazing rebates, bottom door rails — moisture and UV attack are relentless. When paint fails on these surfaces, water penetrates and timber begins to rot from the inside out. By the time rot is visible from the outside, it’s often significantly more advanced underneath.

Addressing timber decay in window frames and doors early is vastly more economical than replacing entire windows. A full window replacement can cost $500–$1,500 per window. A professional repair and repaint, done properly, costs a fraction of that and, when maintained regularly, extends the life of your original joinery indefinitely. The key is acting promptly — before structural rot makes repair impossible.

Our plastering, gyprock repairs, and interior painting services work alongside window and door repairs to provide complete interior and exterior renovation capability from a single, trusted contractor.

Frequently Asked Questions — Window & Door Repairs

How do I know if my window frames have rot?

Signs include soft or spongy timber when you press it, paint that bubbles or peels for no obvious reason, visible cracking or splitting at the base of frames, and discolouration around the frame perimeter. Probe with a screwdriver — sound timber resists penetration; rotted timber will give way with light pressure. If you’re unsure, call us for a free assessment.

Can rotted window frames always be repaired, or do they sometimes need replacing?

Minor to moderate rot can almost always be repaired successfully using epoxy consolidant and filler systems. Structural rot that has compromised the frame’s ability to hold glass or hardware may require partial or full replacement. We’ll give you honest advice on what’s repairable and when replacement is the better long-term investment.

Can you repaint just the exterior of windows, or do you do both sides?

We can do either — or both. Interior and exterior sides of window frames are often painted at the same time for efficiency, particularly if the whole house is being repainted. For targeted repair work on external frames, we can work on the exterior only. We’ll agree the scope during the quote.

My front door is sticking — can you fix it without repainting?

Yes. Door planing and hinge adjustment are straightforward carpentry tasks we can handle independently of painting. However, if the timber has swollen due to moisture — which is often what causes sticking — treating the bare timber with preservative and repainting it is a wise precaution to prevent the same issue recurring.

What paint do you use on exterior window frames and doors?

We use premium alkyd or acrylic exterior gloss paints from Dulux or Taubmans, appropriate for timber joinery. These provide hard, washable, UV-resistant surfaces that stand up to coastal conditions. Where appropriate (e.g. frames that have historically had adhesion problems), we use specialist primer systems for maximum adhesion and longevity.
