Why VPI Accreditation Matters
Anyone can claim to do EWI. Not everyone can back it up with a manufacturer's stamp of approval. As a VPI Trusted Contractor, JMJ meets the highest standards for specification, installation, and workmanship — independently verified.
Insurance-Backed Warranty
Your 10-year warranty is backed by VPI's manufacturer insurance — not just a handshake promise. It covers the full system once installed to specification.
Correct Specification, Every Time
VPI provides free technical advice and specification writing. Your project is designed right before a single board goes on the wall.
Independently Verified Quality
JMJ has been assessed and approved by VPI directly. This isn't a self-awarded badge — it's a standard we've earned and have to maintain.
Protects Your Property Value
A VPI-backed installation is fully documented and transferable. That's a genuine asset when it comes to selling or letting your property.
No Corners Cut on Materials
As a Trusted Contractor, we use only approved VPI render systems — Coloured Monocouche, thin coat, EWI, and lime renders applied to spec.
Technical Support Included
Every project benefits from VPI's free technical support line. You're not just hiring a team — you have the manufacturer behind every job.
10 year Warranty
Manufacturer-Backed.
Insurance Protected.
When JMJ completes your EWI or rendering project, you receive a VPI 10-year manufacturer warranty — insurance-backed and covering the full installed system. This is only available through officially registered Trusted Contractors like JMJ. It's the strongest guarantee available in the industry, and it's included as standard on every qualifying project.
