We started this business to help our community members when they find themselves in difficult situations.Having lived and raised our family here for the past 30 years, we know this area intimately and can identify the best people, organizations, and businesses to guide you through your situation.Every person who reaches out to us is important, and we genuinely care about helping them—whether directly through our services or by connecting them with the right resources.We understand how difficult making the call can be, and we will work with you so the remaining steps can be much less daunting.
When you call us, expect an understanding and empathetic response from someone who is ready to listen, evaluate, and offer you options.If we are not the right fit for your needs, we will connect you with the right information or resources to help you in your situation.
If we are able to help, we next schedule a walk-through estimate in person, where we will assess the situation/environment to provide an informed estimate.
Quotes will be provided within 24 hours, if not the same day. We understand the urgency behind many of the situations we address, so we make ourselves reachable 24/7.
Your privacy is of the utmost priority to us.We take care to be discreet, arriving in unmarked vehicles to your home and wearing layman’s clothes so as not to arouse attention from neighbors.If you prefer, we are happy to change inside the home for your comfort and an added layer of privacy.
We are careful to conceal any biohazardous waste, sealing waste in regular trash bags to bring outside for disposal.Your contact details are kept securely private, and are never under any circumstances shared with or sold to third-party companies.
We ask upfront what communication you are comfortable with and can use specific methods of contact as desired—texts only, no voicemail, email only, etc.We limit communication to the person who contacted us because we don’t assume who you want informed.
A past client chose to work with us, amid other estimates, specifically for the empathy we brought to the situation.She felt heard, and as if we genuinely cared and understood her challenges.She was very pleased with the caliber of our work, and the sensitivity we showed her family in a tough time.
One client felt overwhelmed with the situation, and was very relieved and impressed by our management of the logistics pertaining to the job.
We take care to consider all details and plan ahead to make the client’s experience as effortless as possible.
In another case, a client thought she had a hoarding issue, but after our visit we realized she just needed an organizer—not a trauma team. We told her that honestly and referred her to the right help. She sent a thank-you note for simply listening and caring.
You’ll have a clear understanding of what’s included from the start—and ongoing updates throughout.If something feels off, we adjust.You’ll hear from us afterward—not just to close the loop, but to ask how it felt and make sure you’re still supported.
Satisfaction isn’t a policy—it’s the outcome we’re aiming for.We make sure the job is completed safely, thoroughly, and with your comfort in mind.We take the time to listen and make sure your questions are answered before we consider it done.
