Home: Testimonials

Sentinels is efficient and reliable.  I utilized their leak detection services at a stand-alone house and at a residential 35 unit complex.  They were on time and efficient as well as budget friendly.  It’s hard to find reliable suppliers that pitch up on time.
Would you recommend? Yes.
