What This Service Includes
Water heater installation is more than just replacing the unit.
The work is planned around the existing setup so everything connects properly and runs the way it should.
Depending on the home, the installation may include:
✔ Removal of the existing water heater
✔ Installation of a new tank or tankless system
✔ Updating shutoff valves and water connections when needed
✔ Adjusting supply lines to fit the new unit properly
✔ Installing an expansion tank when required
✔ Opening and restoring walls if access is needed
Each installation is handled as a complete job so nothing is left unfinished or out of place.

How We Handle Water Heater Installations
Every installation starts with reviewing the existing system. Some homes allow for a direct replacement, while others need adjustments to the piping, valves, or layout to get everything working properly.
The installation is planned so the new water heater fits the space and connects cleanly. When access is limited, the work may include opening the wall to reach the lines and complete the installation correctly.
In those cases, the project is carried through from plumbing to drywall repair and finishing so the space is left clean and consistent — part of the "From the Pipe to the Paint" approach.

When a Water Heater Needs Replacement
At Altadena Handyman, we see the water heater as part of the home’s overall plumbing system — not just a single unit.
Water heaters rarely fail all at once. In most cases, there are early signs that the system is starting to wear out or no longer working the way it should.
Common situations where replacement is needed:
✔ Water heater is 8–12+ years old
✔ Hot water runs out faster than before
✔ Leaks or moisture around the unit
✔ Rust-colored water or corrosion on connections
✔ Unusual noises coming from the tank
✔ Inconsistent water temperature
If you're noticing these signs, a professional inspection can determine if a repair is possible or if a more efficient replacement is the safer choice.
In some homes, the issue goes beyond the water heater and comes down to how the system is set up.
Looking at the full setup helps decide whether a simple replacement is enough or if adjustments are needed.
Types of Water Heaters We Work With
Homes use different types of water heaters depending on the setup, space, and how hot water is used throughout the house.
We work with the most common residential systems, including:
Gas water heaters
Electric water heaters
Tankless water heaters
Each type has its own requirements, and the installation is adjusted so everything fits properly and runs the way it should.

Frequently Asked Questions
How long does a water heater installation take?
Most standard installations are completed in one day. If the project requires adjustments, venting updates, or wall access, the timeline depends on the setup and is explained clearly before the work begins.
Do you install both tank and tankless water heaters?
Yes. We work with gas, electric, and tankless water heaters. Each installation is handled so the connections, venting, and overall setup match the system and the home.
Do you handle drywall repair if the wall needs to be opened?
Yes. When wall access is needed to reach plumbing lines, the drywall repair, texture matching, and paint are completed as part of the same project — part of the “From the Pipe to the Paint” approach.
How do I know if my water heater needs to be replaced?
Common signs include inconsistent hot water, leaks, unusual noise, or the unit being 8–12+ years old. Looking at the full setup helps determine whether a repair makes sense or if replacement is the better option.
