Annual Maintenance: RV Services Near Denver

Our RV annual maintenance service packages are designed to keep your RV, airstream, or motorhome protected, maintained, and ready for adventures, all year round. We provide all recommended annual services, from winterizing your RV’s water systems, to springtime de-winterization, sanitizing, roof inspections, bearing packs/brake checks, deep cleaning, and more.

Winterization Services in Denver: Protect Your RV from Cold Weather Damage

Colorado winters can be tough on RV systems. When we winterize your RV, We ensure all water is properly drained and protected so your RV plumbing and appliances stay safe from freezing damage. Our winterization process is performed by master technicians and includes:

  • Drain & Protect Water Systems: Blow out all water lines, drain the freshwater tank, and circulate RV-safe antifreeze.
  • Appliance Preparation: Winterize water heaters, ice makers, and other water-fed appliances.

Spring De-Winterization & Sanitizing at Master Tech RV in Commerce City

When spring arrives, we’ll flush antifreeze from your system, sanitize your fresh water tank, and prepare your RV for safe summer travel.


Spring service packages include:

  • Flush Antifreeze: Completely remove winterization fluids from the system.We then run a water systems check to make sure there are no leaks in the pipes or around fittings and valves. 
  • Water System Sanitization: Once your RV is de-winterized, we sanitize the fresh water system to eliminate bacteria, odors, and lingering antifreeze, ensuring clean water for every trip. 
  • Annual Preventative Maintenance – Prevent Problems Before They Start

Our Annual RV Maintenance Services

Our annual RV maintenance services help you avoid unexpected repairs while extending the life of your RV.


  • Roof Seal Inspection: Check for cracks, lifting, and leaks in all seals. This is particularly important if you do not store your RV inside during the winter.
  • Brakes & Bearings (Travel Trailers Only): Repack wheel bearings and inspect brakes every 8,000–10,000 miles to ensure safe towing.
  • HVAC Service: Clean evaporator and condenser coils, remove debris, check drains, test amp readings, and make sure your A/C and heating systems run efficiently.
  • Battery and Solar Power System Check: We test your entire RV power system — batteries, shore power, solar panels,and confirm your batteries are charging correctly. We also inspect your inverter and converter to ensure safe, reliable operation of your 12V and 120V systems.
  • LP gas leak test: Using professional-grade gauges and leak detection tools, we check your propane system for leaks or pressure drops. Recommended after storage, before long trips, or anytime you suspect an issue — propane safety is critical for every RV.
  • RV Cleaning, Waxing & Ceramic Coating Services: Keeping your RV clean and protected isn’t just cosmetic — it prevents long-term damage from UV rays, road grime, and weather. Our detailing services include interior cleaning, exterior washing, protective waxing, and long-lasting ceramic coatings.
  • Interior RV Cleaning: We offer thorough interior cleaning services to refresh your living space. This includes dusting, vacuuming, surface cleaning, and bathroom/kitchen wipe-downs. Ideal for prepping before a trip or tidying up after one.
  • Exterior RV Cleaning: Our exterior washes remove dirt, bugs, sap, and road film. We use RV-safe soaps and soft tools to avoid scratching paint, decals, or fiberglass.
  • Waxing Services: Waxing adds a layer of protection to your RV’s surface while restoring shine. Recommended a couple of times a year to help guard against UV damage and make future cleanings easier.
  • Ceramic Coating (Premium Option): For long-lasting protection, we offer professional-grade ceramic coatings. This service creates a durable, high-gloss barrier that resists oxidation, fading, and staining — lasting far longer than traditional wax.
