Caulking Contractors Melbourne | Hayes Height Services

Commercial caulking
Melbourne

Sealant is the cheapest line of defence on your building, and the most ignored. Every panel joint, window perimeter and expansion joint relies on it to keep water out, and it wears out. Most building owners are never told that.

Hayes Height Services was founded by a caulker. We run recaulking and remedial sealant programs for strata and facility managers, and production caulking for builders on new construction. Joints cut out, prepped properly, backed correctly and tooled by people who have done nothing but this for years.

Because we work on ropes, we reach every joint on the building without scaffold or boom lifts. That is usually the difference between a recaulk quote that gets approved and one that sits in the too-hard basket.

Failed joints

Signs your building needs recaulking

All of these photos are from real Melbourne buildings we have inspected or repaired. If any of them look familiar, your sealant has reached the end of its life and water is likely already getting in.

Cracked & perished

Sealant that has lost its flexibility splits like dry clay. It can no longer move with the building, so it can no longer seal it.

Things growing in joints

Moss and weeds need constant moisture. If they are living in your joints, so is water.

This joint looked fine from the ground. Squeeze it and water pours out. Everything behind it is wet.

Joints never caulked

This joint was never sealed, likely because it couldn't be reached safely and got forgotten about. Exactly the kind of joint that gets missed without rope access.

What we do

Caulking services Melbourne

Recaulking & remedial programs

Full building recaulks for strata and facility managers. Old sealant cut out, joints cleaned and primed where needed, new backing rod and sealant installed and tooled. Itemised quotes so you know exactly what you are paying for.

Facade & expansion joints

Precast panel joints, expansion joints, control joints and facade movement joints. The joints that do the most work on a building and fail first when ignored.

New construction caulking

Production caulking for Melbourne builders. We turn up when booked, keep pace with your program, and hand over joints that pass handover inspection the first time.

Leak-driven joint repairs

Water coming in and nobody can find where? Failed caulking is the most common answer. We water test suspect joints, find the entry point and reseal it, with photos of everything we find.

Window & curtain wall perimeters

Window perimeter seals, curtain wall joints and glazing seals at any height on the building. A common leak source on towers and a quick fix on ropes.

Joint inspections & reports

Not sure what condition your building is in? We inspect and photograph every joint line, tell you what is failed, what is on the way out and what is fine, so you can budget properly instead of guessing.

Why buildings leak

Failed caulking is how water gets in

When a building leaks, everyone looks at the roof. In our experience the answer is just as often a 15 year old joint that quietly gave up. Water tracks through the failed sealant, into the cavity, and shows up two floors down in someone's apartment, nowhere near where it got in.

By the time it is visible inside, you are paying for plaster, paint, carpet and an angry owner, when the actual fix was a few hundred dollars of sealant. Recaulking is the cheapest facade repair there is. Waiting is the expensive part.

Why Hayes Height Services

Founded by a caulker

Plenty of companies offer caulking as a sideline. For us it is the trade the business was built on. Our director spent years running caulking crews on Melbourne's biggest commercial projects before starting Hayes Height Services, and still picks up a gun.

Caulker-led, not caulker-adjacent. Joint prep, backing, primers, tooling. The details that decide whether a joint lasts 15 years or 3 are second nature here.
Rope access changes the maths. No scaffold and no boom hire means the access cost on your quote is close to zero. Most of what you pay goes into the actual work.
We show up. Builders know the pain of a caulker who vanishes mid program. We book it, we turn up, we finish it.
Paperwork sorted. SWMS, insurances, ITPs and photo reports without being chased. Everything your builder or OC needs.
Deal with us directly. You talk to the people doing the work, from quote to completion.

Common questions

Caulking FAQs

How long does external caulking last?

Quality external sealant typically lasts 10 to 15 years, less on joints with heavy sun exposure or a lot of building movement. Most owners never think about it until joints fail, but sealant is a wear item like a roof membrane, and it expires.

How do I know if my building needs recaulking?

Cracked or crazed sealant, joints pulling away from panel edges, gaps you can see daylight or backing rod through, vegetation growing out of joints, or water stains below joint lines. Unexplained leaks into apartments or offices are very often failed caulking. Not sure? Send us photos and your building address and we'll tell you.

Is failed caulking causing my building to leak?

Very possibly. Failed joint sealant is one of the most common sources of water ingress in Melbourne buildings. We regularly water test suspect joints and find water passing straight through perished sealant into the wall cavity. The good news: recaulking is one of the cheapest facade repairs there is, especially compared to the internal damage a leak causes if left.

Do you need scaffolding to recaulk a building?

No. We work on ropes, which means we reach every joint on the building without scaffolding or boom lifts. That removes the single biggest cost on most recaulking quotes, avoids weeks of scaffold on your facade, and means no disruption to tenants, car parks or footpaths.

How much does recaulking cost in Melbourne?

It depends on joint size, total metres, access and how much old sealant needs cutting out. Larger recaulk programs are often priced per lineal metre, smaller or more complex jobs are quoted as a full scope. Send us your building address and some photos of the joints and we'll quote within 24 hours. For larger buildings we can inspect on site first, usually within the week.

What sealants do you use?

We run APTC, Pasco, Sikaflex, Tremco, Maxisil and Sabre Seal products, matched to the joint type, substrate and movement. Every joint is cut out, cleaned, primed where required, backed with the correct rod and tooled properly. The product matters, but preparation is what makes a joint last.
