Caravan & Motorhome Window Installation & Repairs

Need better views or a brighter, fresher feel in your caravan or motorhome? We handle full window installations and repairs in our workshop, boosting ventilation and aesthetics while preventing water ingress.


Why Leisure Vehicle Window Issues Can Snowball Fast


A small gap or aged seal around your window might start with a bit of fogging but over time it leads to mould, rot, and costly damage. Left unchecked, moisture can ruin interior boards, insulation, and safety of your van’s structure.


Expert Workshop Repairs & New Window Installations


In our County Antrim workshop we carefully remove your window, assess the frame, replace seals, or even fit a new window depending on your needs. We also enhance your van’s air flow and style, especially useful for conversions where light is everything.


Peace of Mind from Quality Work


  • Repair seals or replace windows for better weatherproofing
  • Fit campervan-standard windows for those converting or improving space
  • Skylight installation and repairs also covered


Every job uses best-practice materials and workmanship. You’ll get a clear quote, precise craftsmanship, and a solution that lasts.

  • Can you repair a leaking caravan window?

    Absolutely. We identify the cause of leaks, such as failed seals or frame cracks, and carry out precise repairs to stop water ingress and prevent damp.

  • How do I know if my caravan window needs replacing?

    Signs include condensation between panes, difficulty opening or closing, cracked acrylic, or visible water stains. If you're unsure, drop the van off and we’ll assess it for free. Obviously get in touch first!

  • Are your caravan window installations done at my location?

    No, all window replacements and major repairs are workshop-based. This allows us to carry out full frame removals, sealants, and alignments using specialist tools in a controlled environment.

  • Do you supply replacement windows for older caravans or motorhomes?

    Yes, we can source or fabricate replacements for many older caravan models. If a direct match isn’t available, we’ll advise on compatible alternatives.

  • How long does a caravan window replacement take?

    Most window replacements are completed the same day. More complex jobs or hard-to-source windows may require a longer lead time, we’ll confirm this at booking.

  • Can you fit new windows or skylights to improve light and airflow?

    Yes. If you're looking to brighten your caravan or increase ventilation, we can install new windows or rooflights in suitable areas of the body shell.
