Best builders & renovation companies in Joondalup & Perth’s northern suburbs (2026)
Table of Contents
These are the best-rated builders and renovation companies working Joondalup and Perth’s northern suburbs, from the established brick-and-tile pockets of Duncraig, Kingsley, Woodvale, Padbury, Hillarys and Sorrento, out through Joondalup, Wanneroo and Ocean Reef, and up the coast into the growth-corridor estates at Banksia Grove, Tapping, Butler, Alkimos, Eglinton and Yanchep. They’re ranked on real Google reviews, not on who paid us. Building is a service-area trade, run off a ute, a site office and a project schedule rather than a shopfront, so this is an honest read of the operators genuinely working the northern-suburbs catchment, whether you’re after a new home, a knock-down-rebuild, a second storey, an extension, or a kitchen and bathroom renovation. One thing to know up front: builders collect far fewer Google reviews than plumbers or pest controllers, because most people build or renovate once or twice in a lifetime, so the review counts here look smaller than on our other trade pages. That’s normal, and we’ve weighted for it. Below you’ll find what building and renovation work really costs in WA in 2026, the registration and insurance a WA builder legally must carry, the deposit and payment rules that protect you, the warning signs of a dodgy contract, and a checklist to run before you sign anything.

- Google reviews do the ranking. We start with every builder’s live Google star rating and the number of reviews behind it, pulled fresh from Google Maps.
- Rating, weighted by volume. A 5.0 off one or two jobs isn’t proof yet, so we weight the score by review count. A proven rating from a solid base of clients counts for more than a perfect score from a handful. Perway Construction Services in particular carries the deepest record on the page, at 45 reviews.
- Fewer reviews than other trades, on purpose. People build or renovate rarely, so builders gather far fewer Google reviews than, say, a plumber or a pest controller who does dozens of jobs a week. That means a builder with 20 or 30 genuine reviews already has a strong track record for this trade. We’ve judged these on the builder yardstick, not against the review counts you’d see on our plumbing pages.
- Serving the northern suburbs, honestly framed. Building is a mobile trade and most builders list as a service area rather than a shopfront, so we haven’t claimed a specific home suburb for anyone we couldn’t verify. Every operator here surfaced working the Joondalup and northern-suburbs catchment. We’ve deliberately left off the big statewide project-home franchises whose review pools span the entire metro, because their star rating tells you little about the job you’d get up north.
- Builders, not suppliers or trades in isolation. A building search on Google pulls in hardware yards, kitchen showrooms and single-trade subbies. We leave those out and keep the list to genuine building and renovation companies, along with anything sitting below a real rating and review bar.
- Paid spots are labelled, and never jump the queue. When a business pays for a “Featured” spot it’s marked as such. The review-based order below does not change to favour a payer. Right now, no spots are sold.
Perway Construction Services
A clean 5.0 held across 45 reviews is a genuinely strong record for a builder, because building reviews are hard-won, one per project rather than one per week, and keeping a perfect score over that many clients means people have been happy right through to handover. That’s the deepest, best-tested record of any builder on this page, which is exactly what you want when you’re handing over a big chunk of money and a year of your life to a project. For most homeowners weighing up a new build, a major renovation or an extension in the northern suburbs, this is where we’d start the quoting. A steady run of recent reviews makes them easy to check yourself before you shortlist.
View listing & contact ▸Nemo Home Premium
A 5.0 across 27 reviews is a strong, well-tested record for a home builder, and it’s the second-deepest review base on this page. The name points to a home-building focus, the sort of firm you’d talk to about a new house or a custom build up in the northern corridor. A perfect score held over that many jobs is a solid sign the finish and the handover have landed well for past clients. As always, read the recent reviews yourself, look for detail on the actual build, and line them up against a couple of the others before you commit.
View listing & contact ▸Jubilee Home Builders
A 5.0 across 14 reviews is a strong record for a home builder, and the name says exactly what they do, building homes. That makes them a natural quote for a new house or a knock-down-rebuild on an established block, which is common right through Duncraig, Kingsley, Padbury and the coastal suburbs where owners are pulling down a tired 70s or 80s house and building new. The review base is smaller than the top two, so it’s a slightly shorter track record, but a perfect score over a genuine run of jobs makes them well worth a shortlist quote. Ask to see a recent finished home like the one you’re after.

A note on the order: builders earn far fewer Google reviews than most trades, so the counts here are smaller than on our plumbing or pest pages, and that’s expected, not a red flag. We weight the star rating by the number of reviews, so a proven record from a deeper base edges out a perfect score from a handful. That’s why Perway Construction Services (5.0 from 45) sits on top and PK Construction (4.4 from 15) rounds out the ten. Every builder here clears our quality bar. As always, get two or three quotes before you sign, and judge each on their own recent, project-specific reviews.
Also worth a quote in the northern suburbs
For the deepest, best-tested record on the page, Perway Construction Services (5.0 from 45) carries by far the most reviews and is the safe first call for a new build or a major renovation. For a new home or custom build, Nemo Home Premium (5.0 from 27) and Jubilee Home Builders (5.0 from 14) both hold clean scores over a genuine run of jobs. If your project is a renovation, an extension or a second storey rather than a brand-new house, SDR Home Renovations (5.0 from 11), Prime Builds & Renovations (5.0 from 10) and Aspire Homes & Renovations (5.0 from 7) all trade on that reno work by name. Distinct Building Company (4.8 from 17), Buildmark (4.9 from 12), SOL Construction (4.8 from 12) and PK Construction (4.4 from 15) round out a strong field of general builders. Whoever you call, match the builder to the job, a project-home specialist and a bespoke renovator are not the same animal, ask to see a recent finished job like yours, and always line up two or three fixed-price quotes on the same scope so you’re comparing apples with apples.
What building and renovation work actually costs in Perth (2026)
Nobody likes ringing a builder blind on price. These are honest WA ballpark ranges for the common jobs, GST included. They’re a guide to keep you from being overcharged, not a quote, and building costs move with your finishes, your block and the market, so the spread on each line is wide for a reason. Costs have climbed hard over the last few years on the back of trade shortages and material prices, so treat these as 2026 starting points and get your own job priced in writing after a builder has seen the property and the plans. In the northern suburbs the work splits two ways: renovating, extending and adding a second storey to the established brick-and-tile stock through Duncraig, Kingsley, Woodvale, Padbury, Hillarys and Sorrento, and new homes or knock-down-rebuilds out in the coastal growth corridor at Banksia Grove, Butler, Alkimos, Eglinton and Yanchep. Coastal blocks near the water carry their own cost, salt-rated fixings and finishes, and sandy or limestone ground can lift the price of footings and earthworks.
| Job | Typical WA range | What pushes it up |
|---|---|---|
| Bathroom renovation (full strip-out and refit) | $18,000-$40,000 | Layout changes, waterproofing, tiling area, fixtures and tapware, moving plumbing, second-storey access |
| Kitchen renovation (full) | $22,000-$60,000 | Cabinetry and stone, appliances, moving services, structural wall removal, high-end finishes |
| Room addition / rear extension (ground floor) | $2,500-$4,500 / m² | Site access, footings on sandy or limestone ground, matching the existing roofline and brickwork, finishes |
| Second-storey addition | $280,000-$600,000+ | Engineering, existing footings, staying in the house during the build, structural upgrades, ocean-view glazing |
| Whole-house renovation (cosmetic to structural) | $120,000-$400,000+ | Extent of structural work, kitchen and bathrooms, re-wire and re-plumb, age and condition of the home |
| New custom home (build only, per m²) | $2,200-$4,000+ / m² | Single vs double storey, spec level, block slope and soil, coastal exposure, bespoke design |
| Knock-down-rebuild (demolition + new home) | $450,000-$900,000+ | Demolition and site clearing, asbestos removal on older homes, home size and spec, coastal block |
| Granny flat / ancillary dwelling | $120,000-$260,000 | Size, kitchen and bathroom fit-out, connecting services, site access, whether it’s transportable or built on site |
| Patio, alfresco or outdoor living | $8,000-$40,000 | Size, roof type, decking, flooring, whether it ties into the house structure |
| Home indemnity insurance (builder arranges, on work over $20k) | Built into contract | Contract value; legally required in WA and passed on in the build price |
The northern suburbs carry their own building conditions worth pricing in. The established suburbs, Duncraig, Kingsley, Woodvale, Greenwood, Padbury, Hillarys and Sorrento, are full of 1970s to 1990s brick-and-tile homes that renovate and extend well, but on an older home budget for surprises once the walls open up: asbestos in eaves, fences and old sheeting, dated wiring and plumbing that a good builder will flag before you sign, not after. Out in the growth corridor, Banksia Grove, Tapping, Butler, Alkimos, Eglinton and Yanchep, the work is mostly new homes and knock-down-rebuilds on sandy coastal blocks, where site works, footings and fill can add real money on a sloping or reactive site. Anywhere near the coast, from Ocean Reef and Mullaloo up to Mindarie and Alkimos, salt air is a genuine factor, so quality external fixings, finishes and glazing that stand up to it are worth paying for rather than cutting. And whatever the job, the big cost driver is scope creep: every change once the build starts is a variation, and variations are where a tidy fixed price quietly becomes an open cheque. Lock the scope and the finishes down in the contract before a shovel hits the ground.
Don’t get ripped off: red flags
- Not a registered builder. In WA, residential building work over a set value must be carried out by a builder registered with the Building Services Board. Ask for the registration number and check it on the Building and Energy (DMIRS) register before you sign. An unregistered “builder” leaves you with no proper comeback.
- A deposit over the legal cap. Under WA’s home building contract rules the deposit is capped at 6.5% of the contract price. Anyone asking for 10, 20 or 30 per cent up front is breaking the rules and putting your money at risk. Walk away.
- No home indemnity insurance. For residential work over $20,000, the builder must take out home indemnity insurance and give you the certificate before they take a deposit or start. It protects you if they die, disappear or go insolvent mid-build. No certificate, no start.
- No written contract, or a vague one. Building work over the WA threshold needs a proper written contract with a fixed scope, a fixed price or a clear pricing basis, and a schedule of progress payments. A one-page quote with “the rest TBC” is how disputes start.
- Progress payments not tied to stages. You should pay in stages against work completed, deposit, slab, plate height, lock-up, fit-out, practical completion, not big lump sums ahead of the work. Paying well ahead of the build leaves you exposed if it stalls.
- The quote is thousands cheaper than everyone else. On a build, the lowball quote is usually the most expensive in the end, either it’s missing scope that comes back as variations, or the finishes are stripped down to hit the number. Compare quotes on identical scope and specification.
- Cash discounts and “start Monday” pressure. A builder pushing a cash deal, no contract, or urgency to sign today is a builder to avoid. Good builders have a waitlist and work to a contract.
- Vague on the building permit. Nearly all structural work needs a building permit from the local council or a private certifier. If a builder shrugs off permits or offers to “do it without”, you wear the risk when you sell or insure.
- No allowances spelled out. Watch for “prime cost” and “provisional sum” allowances set artificially low, for tiles, tapware, flooring or site works, so the headline price looks sharp and blows out later. Ask what each allowance assumes.
- Won’t give references or show finished work. A builder proud of their work will happily point you to a recent finished home or a client to ring. Reluctance is a tell.
Before you hire: quick checklist
- Registered builder. Confirm the builder or company holds current registration with the WA Building Services Board and check the number on the Building and Energy register. It’s a legal requirement for residential work, not a nice-to-have.
- Written contract on the right terms. Get a proper written building contract with a fixed scope, the price or pricing basis, the progress-payment schedule and the finish allowances all spelled out before any money changes hands.
- Deposit within the cap. Check the deposit is no more than 6.5% of the contract price, the WA legal maximum. Anything higher is a warning sign.
- Home indemnity insurance certificate. For work over $20,000, sight the home indemnity insurance certificate before you pay a deposit or let work start.
- Building permit sorted. Confirm who’s obtaining the building permit and that it’s in place before structural work begins.
- Right builder for the job. Match the builder to the project, a volume new-home builder, a custom builder and a renovation specialist each suit different work. Ask to see a recent finished job like yours.
- Allowances and variations. Understand every prime-cost and provisional-sum allowance, and how variations are priced and approved, before you sign. This is where budgets blow out.
- Recent, specific reviews and references. Look for recent reviews that mention the actual build or reno, and ask for a client or two you can call. A steady stream beats one old burst of five stars.
Frequently asked
How did you rank these builders?
By their live Google star rating and the number of reviews behind it, pulled from Google Maps. We weight the rating by review volume so a proven score isn’t leapfrogged by a perfect score from one or two jobs. Builders gather far fewer reviews than most trades because people build or renovate rarely, so we judge them on the builder yardstick, Perway Construction Services (5.0 from 45) holds the deepest record on the page. We focused on builders genuinely working the northern-suburbs catchment and left off the big statewide project-home franchises whose review pools span the whole metro.
Which areas does this cover?
Joondalup and Perth’s northern suburbs. That runs across Joondalup, Wanneroo, Ocean Reef, Mullaloo, Hillarys, Sorrento, Duncraig, Kingsley, Woodvale, Greenwood, Padbury, Craigie, Heathridge and Edgewater, and up the coastal growth corridor through Clarkson, Butler, Mindarie, Banksia Grove, Tapping, Alkimos, Eglinton and Yanchep. Builders are a service-area trade, so most on this list cover that whole catchment rather than a single suburb.
Are these paid placements?
No. This list is ordered on Google review data. Businesses can pay for a “Featured” spot at the top, which is clearly labelled, but paying never changes the review-based order below. As of this update, no spots are sold.
Why are the review counts lower than your other trade pages?
Because building is a once-or-twice-in-a-lifetime purchase, so builders simply don’t collect the volume of Google reviews a plumber or pest controller does over the same period. A builder with 20 or 30 genuine reviews already has a strong record for this trade. We weight for that, and we judge these on the builder yardstick rather than against the counts you’d see on our plumbing pages.
Does my builder have to be registered in WA?
Yes. Residential building work over a set value in Western Australia must be carried out by a builder registered with the Building Services Board, administered by Building and Energy within DMIRS. You can check a builder’s registration on the public register. Always confirm registration before you sign, and be wary of anyone who can’t give you a number. This is general information, not legal advice, so check your specific job with Building and Energy WA if you’re unsure.
How much deposit can a builder ask for?
Under WA’s home building contract rules, the deposit on a residential building contract is capped at 6.5% of the contract price. If a builder asks for more up front, that’s a warning sign. After the deposit you should pay in stages against completed work, not in large lump sums ahead of the build. Again, general information rather than legal advice, so check the current rules with Building and Energy WA.
What is home indemnity insurance and do I need it?
Home indemnity insurance protects you, the owner, if your builder dies, disappears or becomes insolvent before the work is finished or a warranty issue arises. In WA it’s required for residential building work over $20,000, and the builder must arrange it and give you the certificate before taking a deposit or starting work. Don’t let a build begin without sighting that certificate.
Should I get a fixed-price contract?
For most home builds and renovations, a fixed-price contract on a clearly defined scope is the safest way to keep control of your budget. The catch is variations: any change once the build starts is priced as a variation, and that’s where a tidy fixed price can blow out. Lock the scope, the finishes and the allowances down in the contract before work begins, and make sure the contract sets out how variations are priced and approved.
How often is this page updated?
Monthly. Ratings and review counts move, new builders earn their spot, and we re-pull the data so the list stays honest and current. As northern-suburbs builders build up reviews, expect this list to shift.
