Gas Valve Replacement
When a gas valve fails beyond repair, we replace the entire valve assembly with an OEM-compatible part — typically a millivolt valve for standing pilot systems or an electronic ignition module.
What is gas valve replacement?
Gas valve replacement installs a new, code-rated gas valve when the existing one is faulty or unsafe. We size and install the correct valve, then leak- and CO-test the system before it goes back in service.

Common questions about gas valve replacement.
How often should I have my chimney swept?
The NFPA recommends an annual chimney inspection (Level 1), with sweeping done when buildup reaches 1/8" of creosote. For active wood-burning fireplaces, that's typically once per heating season.
Are your technicians certified?
Our chimney inspectors hold current CSIA (Chimney Safety Institute of America) certifications, verifiable via the CSIA member directory at csia.org. We also have NFI specialists for fireplace installations.
Do you offer emergency service?
Yes — emergency response is available 24/7 (subject to crew availability) for active water leaks, animal trapped in flue, post-fire damage, and storm damage. Same-day in most cases.
Do you provide written quotes before work begins?
Always. We provide a written quote before any work begins, with photos of the issues we found. Final pricing depends on chimney condition and any additional work identified during inspection.
What's the Chimney Care Plan membership?
Chimney Care Plan is our annual maintenance program at $19.99/month ($240/year). Includes: annual Level 1 inspection and sweep ($248 value), priority scheduling, 10% off all repairs, and emergency response priority. Cancel anytime, no contract.
