How much does electrical panel upgrade cost in Katy, TX?

Most Katy homeowners spend between $1,850 – $4,650 on electrical panel upgrade, with an average around $3,000. Local labor prices 3% above the national average, so Katy quotes tend to land at the higher end of national ranges.

Why is electrical panel upgrade more or less expensive in Katy than elsewhere?

West Houston suburb with higher-end finish expectations. Flood-zone rules can affect foundations, decks and fencing.

Do I need a permit for electrical panel upgrade in Katy, Texas?

County or city permits plus HOA approval typically apply. Always confirm current requirements with the local building department before signing a contract, and make sure the permit is pulled by your licensed contractor.

How many quotes should I get in Katy?

Get at least three written quotes from licensed, insured Texas contractors. Comparing line items — not just the bottom line — is the fastest way to spot an inflated bid in the Houston market.

How much does a 200 amp panel upgrade cost?

$2,000 to $4,500 typically, or $2,800 to $6,000 if the meter base and service entrance also need replacing.

How long does a panel upgrade take?

One day for the electrical work, with power out four to eight hours. Utility scheduling and inspection may spread it over a few days.

Do I need 200 amps for an EV charger?

Usually. A Level 2 charger draws 40 to 60 amps; most 100 amp services cannot support it without load management.

Is a permit required?

Always. The utility will not reconnect without an inspection sign-off, and unpermitted work surfaces during a home sale.

What are Federal Pacific and Zinsco panels?

Obsolete panels with breakers that fail to trip. Insurers often refuse coverage and replacement is strongly recommended regardless of capacity.

Can I just add a subpanel instead?

A subpanel adds circuit space, not capacity. If your total service is maxed out, you still need the main upgrade.
