Why Choose Us for Gutter Replacement in Thornlie?
The original guttering on most 1960s-1980s homes around Thornlie is rusted through by now. Replacing it alongside roof restoration is common because the labour access is already there. Original gutters from that era are usually narrow by modern standards anyway, and Thornlie's heavy canopy overwhelms them, water overflows rather than flowing through. Modern high-capacity gutters handle the leaf and debris load better and are made from more durable materials. Replacement starts from $2,000 depending on how much gutter you've got and what's underneath. We often recommend it as part of a full restoration, but it can also be done standalone if your gutters are the main problem.
If your Thornlie home still has original 1960s-1980s guttering, it's likely rusting through. The constant damp from the flat terrain and clay soils, combined with heat expansion in summer, weakens joints and causes slow seepage into fascia and walls. Replacing old gutters with modern high-capacity systems handles Thornlie's heavy debris load better and eliminates the annual rust repair cycle. New gutters are also taller, which helps during heavy winter downpours common in the southeast corridor.

Local Thornlie Expertise
Thornlie is one of Perth's largest and most established southeastern suburbs - 17km from the CBD, first established as a housing estate in the late 1950s (the first homes were occupied in 1957) and built out through the 1960s, 1970s and 1980s with a population built around family homes on generous quarter-acre blocks. Nearly seven decades of settlement has produced a suburb with uniformly aging roof systems and impressively mature streetscapes: eucalyptus, peppermint, and jacaranda trees now 15-20m tall creating a suburban canopy that shades significant portions of roof surfaces across the suburb. The Canning River runs near Thornlie's southern boundary, and the suburb's flat to gently undulating terrain retains moisture longer than hillier areas. At Roof Restorers Perth, we've restored roofs across Thornlie, Forest Lakes, and the wider Maddington corridor with 15+ years of team experience, specialising in the mass-built 1960s-1980s housing stock that defines this suburb.
The result: Comprehensive restoration that brings Thornlie's 40-70 year old roof systems back to full performance - addressing decades of mortar deterioration, canopy moss, and thermal fatigue - backed by a 15-year Dulux manufacturer warranty on materials.

Benefits of Gutter Replacement for Thornlie Properties
New Colorbond gutters and downpipes
Colorbond steel guttering in a colour matched to your roof and fascia, sized and fitted with the right fall to actually carry a Perth downpour, downpipes included.
Stops the overflow doing damage
Rusted and sagging gutters spill water straight into your eaves, walls and footings. A new system catches it and sends it down the downpipes and away from the house.
Replaced as a whole system
Gutters, brackets and downpipes done together and set to the correct fall, not another patch over a length that's already rusting through somewhere else.
Insured and licensed
We carry $10M public liability and have been working on Perth roofs and rooflines for 15+ years, on homes and commercial buildings alike.
Our Gutter Replacement Process in Thornlie
- 1
Assess and measure
We check the existing gutters, downpipes and fascia, confirm what needs replacing, and measure the runs and falls accurately.
Why it matters: Guttering only works if it's sized and angled to carry the roof's runoff.
- 2
Strip the old guttering
The old gutters, brackets and downpipes are removed and the fascia line is exposed and checked.
Why it matters: A clean fascia line is needed to fix the new gutter straight and solid.
- 3
Check and prepare the fascia
We inspect the fascia and mounting points and flag any timber that's gone before we hang new gutter on it.
Why it matters: There's no point fixing good gutter to rotten fascia.
- 4
Install, seal and water-test
New Colorbond gutters and downpipes are fitted to the right fall, joints sealed, and the system run with water to confirm it flows and doesn't leak.
Why it matters: Testing on the day proves the fall and the seals before we leave.
Gutter Replacement in Thornlie - FAQs
Do you provide gutter replacement in Thornlie? ▾
Yes. Roof Restorers Perth provides gutter replacement across Thornlie and nearby Sorrento, Applecross, Port Kennedy. Roof restoration in Thornlie for ageing homes established from the late 1950s through the 1980s, including repointing and tile renewal. Dulux Acratex accredited, 15 year warranty. Free quotes.

How do I know if my gutters need replacing? ▾
Rust spots, seepage stains on the fascia, and holes you can poke a finger through. If they're original to that 1960s-1980s era, they're due anyway. We assess them during inspection and give you a straight answer.
Can I just patch the rusty bits? ▾
Patching buys you maybe a year or two. With our humidity and moisture here, rust spreads fast. Full replacement is better value long-term and usually makes sense when your roof gets done.
Should I replace my gutters or just clean them? ▾
If they're only blocked, a clean does it. Once gutters are rusted through, leaking at the joins, or sagging off the fascia, cleaning won't bring them back and replacement is the fix. We'll tell you straight which yours need.
What are the new gutters made of? ▾
Colorbond steel, in a colour matched to your roof and fascia. It's the standard for Perth conditions, holds up to the sun and coastal air far better than old galvanised guttering.
How long does gutter replacement take? ▾
A typical single-storey home is usually 1 to 2 days depending on the length of guttering and access. We'll give you a fixed price and a timeframe before we start.
Do you replace the downpipes too? ▾
Yes, where they need it. Downpipes are part of the system, so we usually replace them with the gutters to make sure the whole run carries water properly rather than choking at an old pipe.
What if my fascia is rotten? ▾
We'll spot it during the assessment and tell you. Fascia repair is separate work, but we'll flag it up front so you're not hanging new gutters on timber that's about to give way.
Is there a warranty on the work? ▾
The Colorbond material carries its own manufacturer warranty. Note our 12-month workmanship guarantee covers repointing, rebedding, tile replacement and leak repairs — gutter work sits outside it, so we'll set out in writing what applies to your job. We'll confirm the details before you go ahead.
