"Called today for a non-emergency service (no water leaks at the moment).  I scheduled an appointment for the following week.  A couple hours later they called and said they could come today.  Jason arrived a few minutes later.  He was very friendly and professional.  He reviewed the damage from the leak (we had turned off the water).  He was able to quickly determine the likely cause.  After making the fix he double checked to ensure the problem was fixed.  I really appreciated his expertise and ability to ensure the fix worked.  I also appreciated his friendly demeanor.
I have used Kirkwood Plumbing before and they will be the first for me to call.

"The people on the phone and the workers that worked at my house were fantastic. Damien and Ernest were the installer's top rate people. Jack, their license plumber was polite and funny. The only person we didn't care for was Keith He only stopped by to look at what was going on. He was a little rude to my wife and Made her feel Like she was second class in her own home. We Were very shocked by that. We would definitely recommend Jacuzzi to our friends."

"I held off renovating my bathroom because of the stories I heard from friends about their bad experiences. If I’d known sooner about Bath Planet, I wouldn’t have had to. They are outstanding! I’m extremely happy with my new bathroom and appreciate the team that handled the job. They really listened to what I wanted and helped me every step of the way with the design process, and responded to any questions and concerns. The craftsmen paid unbelievable attention to detail, were meticulous in their work during the entire job, respectful and so easy to work with. They completed the job on time and within the budget."

"Great presentation by Nick. Very nice, informative, professional and knowledgeable. Super quality products and vert6competitive pricing. Because of very busy installation schedules, it will take 4-6 weeks before walkin shower remodel can happen. We can wait, no problem. It will be worth it."

"When the service guy arrived he asked what our problem was and showed up the price chart.  He was not pushing any other service and gave us all the details on why the drain was clogging.  He wore lilttle booties to protect our floor and put a rug down while he worked.  Used the rotor to unclog the sink and he even double checked that the drain was cleared.  Also came with a warranty if the same drain should clog again.

Plumbing questions, answered by experts

You can unclog a double kitchen sink by plunging the side with the garbage disposal. Cover the drain hole on the other side first to avoid creating a mess. Plunge up and down until the water starts to drain. You can also pour in baking soda and vinegar to try and dissolve a clog. 

Yes, you can fit a vanity unit to an existing sink, especially if you plan to custom-build the vanity. With a prefabricated vanity, you’ll likely need to make a few adjustments. It depends on the type of sink, the size of the sink, and the existing plumbing. If you plan to retrofit a sink into a prefabricated vanity, make sure you take precise measurements and that your sink is compatible with the vanity you select. Prefabricated units have a precut sink hole, so you’ll need the size to match your sink.

It is generally recommended to schedule a professional plumbing inspection annually, though an inspection every two years may be sufficient for newer homes. The ideal frequency depends on several factors, including the age of your plumbing system, water quality (such as hardness), and any previous plumbing issues. More frequent checks are advisable for older homes or those with a history of problems. Additionally, if your property has mature trees with extensive root systems, more frequent inspections are beneficial as roots can crack sewer and water lines. Regular maintenance helps identify potential issues early, preventing costly repairs, and can include checking for leaks, inspecting connections, and ensuring pipes and fixtures are in good working condition to prolong the life of your plumbing system.

The biggest sign that your flange leaks is if you notice water at the base of the toilet. The cause is likely due to a poor flange installation, so you might have issues with loose bolts, an uneven flange, or a cracked plastic flange. Add a deteriorating wax seal to this, and you have a recipe for disaster. The best solution is to shut off the water valve, replace the toilet flange, and seal it with a new wax ring.

Annual inspection prevents leaks, blockages, pressure issues, or other problems from developing.
