Campervan Roof Vents & Fans Specialists

Cutting a 400mm hole in your van's roof is a one-way street. A professional installation isn't about convenience; it's about preventing catastrophic leaks. Specialists use precise templates to make a clean cut, even on complex ribbed roofs where a DIY job can easily go wrong. They then build an internal timber frame, adding structural support and creating a solid mounting surface for the vent. This means the unit is secure and the roof panel isn't distorted. The most critical step is the seal. Professionals use high-grade, flexible polyurethane sealants like Sikaflex, applied with a specific technique to guarantee a permanent, watertight bond that withstands years of vibration and weather.

When vetting an installer, ask pointed questions. A good specialist will confidently explain which sealant they use and why it's suited for vehicles. Ask if they build an internal support frame; a "yes" is a huge green flag. You should also inquire how they plan to integrate the fan's 12V wiring into your campervan electrical system, including the fuse rating and wire gauge. Be wary of anyone who is vague on these details or suggests using a generic bathroom silicone, which will fail quickly. A true professional can show you a portfolio of previous installations, giving you visual proof of their clean cuts and tidy wiring.

A professional fan fitting is typically a half-day to a full-day job. Expect to pay between £500 and £900 for a premium extraction fan like a MaxxAir, fully supplied and installed. This price includes the fan, sealant, internal framing, wiring, and labour. A simple non-powered rooflight costs considerably less.
