"What do you do when the gas company turns off your gas due to a leak? You would want a licensed plumbing company that is: quick to respond, has a free estimate, comes out on a Saturday, knowledgeable, on-time, efficient, quality work, courteous, and above all else,...integrity. Jason and his team at J I G Plumbing are all that! We were given an initial estimate, but as the trenching started, he informed us that the repair would not be as extensive as previously thought. He re-calculated the cost, saving us considerable money. Jason and his team patiently answered all our questions and informed us of their progress. Jason also provided photos of damaged areas and the finished repair. The repair was completed professionally and efficiently, and the gas company came to inspect/turn the gas on the same day. We are happy to have J I G Plumbing as our "go-to" for all our plumbing needs in the future!"

"A first time apartment owner and landlord, I needed major plumbing services within the first 6 months of ownership. The first time was a series of gas leaks which were quickly repaired by Western Rooter. The second time was the significant work of adding 2 gas meters and the requisite task of re-routing/adding gas piping. I simply cannot recommend Daniel Westereng and Western Rooter enough. Although the owner John came out to assist in the final bid, Daniel and I worked consistently with SoCal Gas to coordinate the improvements. Daniel was quick to return texts, calls, e-mails and worked diligently with all the parties to get the job done. If you need a plumber, save time and call Western Rooter. Tell them to send Daniel Westereng and he will do a fantastic job!"

Plumbing questions, answered by experts

Check your water meter during periods of no use; any dial movement confirms a hidden leak. You must schedule plumbing service if you receive high-usage alerts or annual backflow testing notices from your utility provider. Furthermore, homes built before 1975 in Ontario require immediate pipe inspections. Finally, visible scale on fixtures or reduced water flow indicates hard water damage demanding professional attention.

Helpful?

Upgrading your plumbing removes mineral scale buildup, which restores consistent water pressure and improves tap water taste. Resolving slab leaks stops mold growth and prevents severe flooring damage. In CA, reliable water supply lines also ensure your evaporative coolers function perfectly during extreme summer heat. Furthermore, fixing leaks and installing efficient fixtures significantly reduces your monthly utility consumption, providing immediate financial relief and daily comfort.

Helpful?

Simple plumbing projects like water heater replacements take just one day of active work. Complex jobs, such as a whole-home repipe, require two to five days of labor. However, you must account for local permit processing and required inspections in Ontario. These administrative steps add several days to a few weeks to your timeline. Extreme summer heat also shifts work to early morning hours, extending the schedule.

Helpful?

Hard water in Ontario accelerates sediment buildup in water heaters and degrades toilet seals or faucet cartridges. You will also experience issues with under-slab copper pipes, which crack due to seismic activity and shifting clay soils. Additionally, intense sun exposure damages irrigation backflow preventers. Finally, mature tree roots infiltrate and separate older clay or cast iron sewer laterals, requiring prompt professional plumbing repairs.

Helpful?

Watch for reduced water pressure or chalky deposits at joints, which indicate past plumbing work ignored Ontario's hard water. You should also check for stress fractures following seismic activity. Additionally, look for ground settlement or soggy yard patches caused by hot, dry weather shifting the soil. Finally, unpermitted alterations will fail to meet CA standards and require professional replacement to ensure your home remains safe.
