Frequently Asked Questions

Please contact us if you cannot find an answer to your question.

Unlike many other plumbing companies, we utilize a standard fee schedule for many of our routine services.  After arriving and diagnosing the problem, you will immediately be informed of the cost to make repairs.  We may occasionally charge for parts and labor for more extensive work, but you will still receive a quote up front prior to any work being performed.  Because we are a service company, we do collect payment on site as soon as the work is completed.  You will never receive a surprise invoice in the mail from Sentry Plumbing.


We accept cash, local checks, and most major credit/debit cards.


We handle all the details and payments involved if a job requires a permit.  This is already included in the price quote you will receive.


We stand by our products and services and provide a 2-year parts and labor warranty free of charge (some exceptions apply).


We have chosen to specialize in service plumbing, in line with our mission, vision, and values.  We do not provide extensive construction or remodel services.  Why?  Because we want to be available in a timely manner for as many of our customers as we can!


Our set prices are continuously reviewed to ensure two things: that our customers receive a fair and honest bill, and that our business is sustainable.  We use professional products to ensure the highest possible value for your hard-earned money.  We offer free estimates to customers within 30 miles of our office.  We can also perform inspection or diagnostic services for a nominal fee, please call the office for details.
