Dedicated solutions for mobile homes with poly-B pipes

Whether you call your home a mobile, modular home, manufactured home or trailer I am your guy for poly-b waterline replacements on Vancouver Island.  My name is Darren Macdonald and I am a Journeyman who specializes on Poly-B pipe replacement for mobile homes across the Nanaimo area and the entire Island.  I have done over 50 complete mobile home re-pipes and will travel to do them.  I do repairs to the membrane and insulation associated with the pipe replacement and previous flood damage.  Normally there is previous damage below the floor which allows rodents to enter the floor space.  Rodents can destroy and devalue mobile homes also.  I seal the membrane better then anyone else I have seen after having personally been under 100s of units for plumbing repairs and emergencies.  Occasionally I replace insulation damaged by rodents as an addition to pipe replacement if requested.  A home can last forever if it is maintained right.  Water and rodents destroy them fast.  The work I do adds more value to the mobile home than it costs.  Most repairmen and other plumbers leave damage and openings in the membrane above the crawl space where no one often looks.  My customers trust me to do it right, start to finish while being certified to satisfy insurance requirements.  My prices are generally much more cost effective than larger companies and there are no other contractors needed.  I seal the minor holes in drywall and do the larger job of the membrane  and insulation below the floor joists.
