Complete Water Heater Installation Services

Everything Included, Nothing Extra
Your water heater installation includes complete removal of the old unit, professional installation of the new system, and all necessary connections and safety checks. We handle permits when required and ensure everything meets local Lexington building codes. Lexington’s older neighborhoods often require special considerations for water heater installations, from navigating tight basement spaces to working with existing plumbing configurations. We’ve handled installations in everything from Colonial-era homes to modern developments, so we know how to work efficiently in any space. You also get a comprehensive warranty that covers our labor for a full year. If something goes wrong with our installation work, we fix it at no charge. That’s our guarantee that the job was done right the first time.

How long does water heater installation take in Lexington?

Most standard water heater installations take 2-4 hours from start to finish. This includes removing your old unit, installing the new water heater, making all connections, and testing the system. Tankless water heater installation typically takes longer, usually 4-6 hours, because it often requires additional electrical or gas line work. Emergency installations can sometimes be completed faster when we’re working with straightforward replacements. The timeline can extend if we discover issues with existing plumbing, electrical connections, or if permits are required. We’ll let you know upfront if we expect any delays and keep you updated throughout the process.
Emergency water heater installation costs depend on the type of unit you choose and any complications we encounter. We provide upfront pricing before starting work, so you know exactly what you’ll pay. Standard tank water heaters typically cost less than tankless systems, but tankless units offer long-term energy savings. We’ll explain your options and help you choose what makes sense for your situation and budget. Emergency service doesn’t mean inflated prices. Our pricing stays consistent whether you call during business hours or need us at midnight. You pay for the installation and equipment, not for the timing of your emergency.
If your water heater is leaking from the tank itself, replacement is your only option. Tank leaks mean the inner lining has failed, and this can’t be repaired reliably. Leaks from connections, valves, or fittings can often be repaired, but if your unit is over 8-10 years old, replacement usually makes more financial sense. Older units that need repairs often develop new problems shortly after. We’ll assess your specific situation and give you honest recommendations. Sometimes a simple repair buys you time to plan for replacement, but we won’t try to sell you a new water heater if a repair will solve your problem effectively.
Yes, we install both gas and electric tankless water heaters throughout Lexington. Tankless systems work well in many local homes, especially those with limited basement space or high hot water demand. Tankless installation often requires upgrading electrical service or gas lines, which we handle as part of the installation process. We’ll assess your home’s requirements and let you know about any additional work needed upfront. The main benefits are endless hot water and space savings, but tankless systems have higher upfront costs. We’ll help you understand whether the long-term energy savings make sense for your household’s hot water usage patterns.
We install quality brands like Rheem, AO Smith, and Bradford White that perform well in Massachusetts’ climate conditions. These manufacturers offer reliable units with good warranty coverage. The best brand for your home depends on your hot water usage, available space, and budget. We don’t push expensive units you don’t need, but we also won’t install cheap equipment that will cause problems later. All the brands we install are readily serviceable in the Lexington area, meaning you can get parts and service when needed. We stock common repair parts and can service what we install for years to come.
Yes, all our water heater installation work comes with a one-year labor warranty. If something goes wrong with our installation within that year, we fix it at no charge to you. This warranty covers our workmanship and installation, separate from the manufacturer’s warranty on the water heater itself. You’re protected both by our guarantee on the work and the manufacturer’s coverage on the equipment. We also offer a seven-day warranty on drain cleaning services and provide free main sewer line camera inspections for new customers. Our goal is your complete satisfaction with both the installation and our service.
