Exterior Plastering and Painting Specialists
Monolithic crack repairs, exterior insulation and weathertightness-focused work for Wellington homes.
About Us
Family-led by Licensed Building Practitioner Lucas Ribas. We help homeowners understand the condition of their exterior and the work that may suit it.
Rendermates is headed by Licensed Building Practitioner Lucas Ribas. With more than a decade of hands-on experience, our family-led team brings care and clear communication to exterior plastering and repair work.
We work across existing homes, renovations and new builds, taking the time to explain what is known, what is still uncertain and how the proposed work fits the building.
Cladding concerns can be hard to read from the outside. We start by understanding the wall, the visible issue and what a useful next step could be.
Rendermates works across Wellington, Lower Hutt, Upper Hutt, the Kāpiti Coast, Masterton and Wairarapa. If you’re unsure whether your home is in reach, ask us.

Our exterior systems & solutions
Different walls, different needs.
Here’s how we sort them.
Every home has its own quirks and substrate. Below are the proven plastering, cladding, and coating systems we use across Wellington, the Hutt Valley, Kāpiti, and Wairarapa to keep your property dry and looking sharp.
Painting & Coatings
Exterior House Painting & Maintenance
Looking for exterior house painting in Wellington? We provide full-house repainting, rendered-home recoating and monolithic crack repairs across Wellington, Lower Hutt, Upper Hutt, Porirua, Kāpiti and Masterton / Wairarapa. Protect your home with a maintenance schedule tailored to your cladding, coating system and local exposure.
Warranty & Peace of Mind:
Our exterior house painting work is backed by a 5-year Licensed Building Practitioner (LBP) workmanship warranty and a 10-year supplier warranty on premium coating systems.
Exterior Maintenance Schedule
Ask about an annual exterior wash and condition check. After assessing your coating system, wall condition and local exposure, we can recommend any touch-ups or recoating and a suitable maintenance interval. The right schedule can vary from one Wellington home to another.

Monolithic cladding repairs
Monolithic Plaster Crack Repairs & Recoating
Looking for monolithic cladding repairs in Wellington? We assess cracks in rendered homes and carry out exterior plaster repairs and compatible recoating. This project involved Sto exterior repainting and crack repairs, backed by a 10-year supplier warranty and LBP workmanship cover. We also serve Lower Hutt, Upper Hutt, Kāpiti and Masterton. The suitable repair method depends on the existing wall system and a site assessment.
Can you resurface and recoat my monolithic plaster home without a full reclad?
In many cases, yes—but first we assess the existing substrate and cladding system. If a repair or recoat is suitable, we explain the proposed work and the warranty terms for the specified system. If further investigation is needed, we will say so before work begins.
Exterior wall insulation & insulated cladding systems
Exterior Wall Insulation for Existing Homes
Considering exterior wall insulation in Wellington? We install exterior insulation and EIFS cladding systems across Wellington, Lower Hutt, Upper Hutt, Porirua, Kāpiti, and Masterton. These systems are designed to improve thermal performance while renewing the outside of your home. Suitability depends on the existing wall, substrate, openings, and weatherproofing details, so we assess the property and confirm the system and applicable warranty before work begins.
Can you add exterior wall insulation to an existing house from the outside?
In many cases, an exterior system can be installed without removing internal wall linings. The existing cladding, substrate, moisture condition and junction details need to be assessed first to confirm whether the selected system is suitable.
New-build exterior plastering & cladding
Exterior Plastering & Cladding for New Builds
Planning a new build in Wellington, the Hutt Valley, Porirua, or Kāpiti? Rendermates installs exterior plaster and cladding systems for new residential projects. As Licensed Building Practitioners in Exterior Plastering, we coordinate the work with your build team and confirm the specified system, scope, and supplier warranty before work begins. The right materials and details depend on the design, substrate, and site conditions.
How do you work with builders on a new exterior plastering project?
We discuss the project scope, sequence and selected cladding system with the build team, then confirm the installation requirements and relevant documentation before work begins.
Exterior building refurbishments
Multi-Unit Refurbishments
Planning an exterior refurbishment for a home or multi-unit building? Rendermates assesses and carries out exterior plaster repairs, recoating and refurbishment across Wellington, the Hutt Valley, Porirua, and Kāpiti. We confirm the visible condition, agree the scope with you, and identify the coating or cladding system before work starts. Supplier warranty terms and workmanship cover depend on the specified system and project scope, and are confirmed in writing.
Can you help plan a multi-unit exterior refurbishment?
We can assess the visible condition of a multi-unit building and discuss the proposed scope with owners, property managers, or body corporate representatives. Access, staging, suitable systems, and warranty terms depend on the building and are confirmed in the project proposal.
Interior & exterior mineral finishes
Venetian Plaster & Polished Feature Walls
Looking to elevate your interior and exterior spaces with seamless, stone-like textures? We hand-apply authentic Venetian plaster, polished Marmorino, and custom mineral finishes across Wellington, Lower Hutt, Upper Hutt, Porirua, and the Kāpiti Coast. Backed by our workmanship guarantee, we craft bespoke indoor feature walls, fireplace surrounds, outdoor entertainment areas, and water-resistant bathroom finishes that add timeless architectural depth to your home or commercial space.
Where can Venetian plaster be applied?
Venetian plaster and polished mineral finishes can be used on indoor feature walls, fireplace surrounds, and selected outdoor areas such as sheltered entertainment spaces. Bathroom applications need a suitable coating and sealing system. The right finish depends on the surface, exposure, and product, so we confirm a suitable option for your project before work begins.
