Campervan Roof Vents & Fans Specialists

Cutting a hole in your van's roof is permanent. While a DIY install can save money upfront, a single mistake leads to persistent leaks, rust, and mould that can ruin your entire build. Professional installers eliminate this risk. They have the correct jigs and blades for a clean cut, avoiding the warped metal a cheap tool can cause. In practice, they also build a sturdy internal timber frame to support the fan and provide a solid mounting point. This frame prevents the roof skin from flexing and ensures the polyurethane sealant, like Sikaflex, creates a permanent, waterproof bond that won't degrade like common silicone.

When vetting an installer, ask specific questions. Enquire about the exact sealant they use and how they prep the roof surface for a perfect bond. A genuine specialist will confidently explain why they use a polyurethane adhesive and not basic silicone. They should also describe how they create an internal frame and route the 12V wiring to a correctly-fused circuit. Be wary of anyone who can't show a portfolio of previous fan installations or gives vague answers. For a standard MaxxAir or Fiamma fan, expect the installation to take half a day to a full day, with a fitted cost typically falling between £600 and £1,200 including the unit.

Finding a trusted fitter used to be a gamble. A platform like CamperBrain simplifies the search by connecting you with vetted specialists whose profiles feature work galleries and verified reviews. This allows you to assess their craftsmanship before making contact and compare installers with experience on your specific van model or desired fan. As a result, you spend less time cold-calling and more time evaluating proven experts. Investing in a professional installation from the start is the smartest decision, saving you from the far greater expense of fixing a leaking roof.
