Water Heater Services Lexington MA

What's Included in Every Installation
Every water heater replacement includes proper permits, code-compliant installation, and thorough testing. We handle gas line connections, electrical work, and venting according to Lexington’s requirements. You get a full year warranty on our labor plus manufacturer warranties on the unit itself. We also provide a free main sewer line camera inspection for new customers—this helps catch potential problems before they become expensive emergencies.

How long does water heater replacement take in Lexington homes?

Most water heater replacements in Lexington take 3-6 hours depending on your home’s setup. Straightforward replacements in accessible basements usually take 3-4 hours. Homes with tight spaces, gas line updates, or electrical modifications may take longer. We factor in permit requirements and inspection scheduling when giving you timing estimates. Lexington’s inspection process typically adds one day to the timeline, but we coordinate this for you. Emergency replacements can often be completed same-day when we have units in stock.
Most Lexington families need a 40-50 gallon water heater, but size depends on your household’s hot water usage. A family of four typically uses 40-50 gallons during peak morning hours for showers, dishwashing, and laundry. We calculate your needs based on bathrooms, family size, and usage patterns. Larger colonial homes with multiple bathrooms may need 60-80 gallon units. Tankless options work well for smaller homes or specific situations where space is limited. We measure your current usage and recommend the right size during our assessment. Getting the size right means consistent hot water without paying for capacity you don’t need.
Yes, Lexington requires permits for water heater replacement, and we handle this process for you. The town requires permits to ensure installations meet current safety codes, especially for gas connections and venting. We pull permits, schedule inspections, and ensure your installation passes on the first try. This protects your home’s value and ensures your homeowner’s insurance stays valid. DIY installations without permits can create insurance and resale issues later. The permit process typically takes 1-2 business days but we coordinate timing so it doesn’t delay your hot water restoration. All permit costs are included in our upfront pricing.
Water heater replacement in Lexington typically costs $1,200-$3,500 depending on the unit type, installation complexity, and any necessary updates to gas lines or electrical connections. Standard tank replacements usually fall in the $1,200-$2,000 range. Tankless units, high-efficiency models, or installations requiring significant modifications cost more. Lexington’s older homes sometimes need gas line upgrades or electrical updates to meet current codes, which affects total cost. We provide upfront, transparent pricing before starting work. You’ll know exactly what you’re paying with no hidden fees or surprise charges when the job’s finished. Our quotes include all labor, permits, and materials needed for a complete installation.
We install major brands including Rheem, Bradford White, AO Smith, and Navien depending on your needs and budget. These manufacturers offer reliable units with good warranty coverage and local parts availability. For Lexington homes, we often recommend Bradford White or Rheem for their durability and performance in New England conditions. Navien tankless units work well for space-limited installations or high-efficiency requirements. We’ll explain the pros and cons of different brands during your assessment. Our recommendations consider your budget, space constraints, and long-term reliability. All brands we install come with manufacturer warranties plus our one-year labor guarantee.
Yes, we provide 24/7 emergency water heater replacement throughout Lexington. When your water heater fails completely, we can often provide same-day replacement if we have appropriate units in stock. Emergency service includes weekends and holidays because water heater failures don’t wait for convenient times. We prioritize complete failures over routine replacements, especially during winter months when hot water is critical. Our emergency service covers assessment, unit procurement, and installation. While emergency calls may include after-hours fees, we’re transparent about all costs upfront. Most Lexington emergency replacements are completed within 24 hours of your call.
