Build the Referral Network That Matches You With the People Who Need You the Most
May 30, 2026
Most grab bar installers, when they're growing their business, focus on what's visible. The website. The Google Business Profile. The Facebook ads. The Nextdoor presence. All of those are worth doing.
None of them are particularly good at matching a trained installer with a family who specifically needs what they do. That match is what produces the kind of work that's satisfying to do and meaningful to the people receiving it — and there's a specific source that delivers it more reliably than anything else.
The most valuable customer relationships any installer builds are the ones that come from referrals by occupational and physical therapists. The reasons are simple, and once you understand them, the rest of your business strategy gets clearer.
My co-founder Emilio Baires has been working in home services for more than twenty years, with grab bar installation as a specialty that developed over that time. Over a thousand installs, zero failures. He's the author of our certification course. And one of the strongest themes that runs through everything he teaches about building a business is this: the professional referral network is where the real growth happens. Marketing helps people find you. Professional referrals send people who already trust you, because someone they trust has vouched for you. Those are different kinds of starting points, and the referred one starts the relationship in a much better place.
Why OTs and PTs are the highest-value referral source
Think about the typical path of someone who needs a grab bar. They're not waking up thinking about grab bars. Something has happened — a fall, a surgery, a worsening of a condition — and now somebody in their care chain is saying, you really should have grab bars installed.
Who is that somebody, more often than not? It's an occupational therapist or a physical therapist. They're the professionals who do home safety assessments. They're the ones writing recommendations in discharge plans. They're the ones the family trusts when they're trying to figure out what to do next.
When the OT says you need grab bars, and here's who I'd call, the family calls. They call the person the OT named, because in that moment the OT is the most trusted voice in their world about exactly this question.
The dynamic with a referred customer is different from the start. They're not wondering whether grab bars are worth the cost — their OT has already explained that. They're not worried about whether you're qualified — the OT named you specifically. They're calling ready to schedule a real conversation, not to comparison-shop. That makes it easier for you to do good work, and easier for them to get what they actually need.
How to actually build these relationships
This is where most installers stop, because building professional relationships feels like a different kind of work than running a service business. It is. It's also worth more than almost anything else you could be doing on a slow Tuesday afternoon.
Emilio's straightforward advice: go to where the OTs and PTs are. Hospitals have rehabilitation departments. So do skilled nursing facilities. Outpatient PT clinics dot every commercial corridor in every American suburb. These are not hidden places. They have addresses, phone numbers, and front desks.
Walk in. Don't show up empty-handed and don't show up with a sales pitch. Bring a small stack of business cards, a one-page sheet that describes what you do, and a brief, professional introduction. Ask if there's an OT or PT supervisor you could leave materials with. If they say yes, leave the materials and follow up a week later with a phone call. If they say no, thank them, leave a card, and move on. There are more clinics than you'll ever exhaust.
Hospital discharge planning is another door worth knocking on. The discharge nurses and case managers in any decent-sized hospital are constantly fielding the question of how a patient's home will be made safe before they're released. An installer who has introduced themselves, left clear materials, and demonstrated they understand the discharge timeline is exactly the kind of resource that ends up on a clipboard somewhere — and gets called the next time a family asks the question.
What therapists actually need from you
Here's the part most installers miss. The OT or PT isn't doing you a favor by referring patients to you. They're solving their own problem, which is that they need somebody reliable to refer their patients to. They get asked the question constantly: who do we call for grab bars? If they don't have a good answer, it falls on them to figure it out — and that's time they don't have.
The installer who becomes the OT's go-to person is the installer who takes that problem off their plate. That means a few specific things.
You answer the phone. When the OT or one of their patients calls, you pick up, or you call back within hours, not days. The OT is going to remember whether you were responsive, because their reputation is on the line every time they refer somebody.
You do good work. This is obvious, but worth saying. An OT who refers a patient to a bad installer hears about it from the patient and from the patient's family, and they will never refer to that installer again. The first job is a test, even if neither of you frames it that way.
You communicate. After the job is done, send a short note to the OT — by email or a quick handwritten card — letting them know the install went well, what you did, and thanking them for the referral. This is not the OT keeping score; it's the OT learning that referring to you is a smooth, satisfying experience. Repeat referrals come from that feeling.
Keep your pricing fair and standard across all of your customers, including referrals. The patients an OT refers are often dealing with significant medical bills. An installer who tries to upsell or who handles the pricing conversation badly puts the OT in a position where the patient comes back complaining. That ends the relationship faster than anything else.
The other professional circles that matter
OTs and PTs are the highest-leverage referral source, but they aren't the only one. The full professional network worth building includes a few others.
Home health aides and home health agencies. These are the people who are physically in older adults' homes, helping with daily activities. When the home health aide notices that Mrs. Smith is having trouble getting off the toilet, they're often the one who suggests a grab bar. An installer who has built relationships with the local home health agencies — both the franchise ones like Visiting Angels and Home Instead, and the independent operators — gets called for those jobs.
Senior service provider groups. Most counties have a formal or informal network of professionals who serve older adults: senior care coordinators, senior move managers, real estate agents who specialize in older clients, geriatric care managers, elder law attorneys, insurance agents. These groups usually meet monthly, often over breakfast or lunch, and welcome new members from adjacent professions. An installer who shows up regularly to those meetings becomes a known face. Known faces get referred.
Real estate agents who specialize in senior transitions are also worth building relationships with. The ones to invest time in in are those who specialize in helping older clients downsize, sell the family home, or move to a smaller place. They're constantly dealing with families who are about to need accessibility modifications, and they refer constantly when they trust someone.
What this is really about
Marketing brings in customers who don't know you yet. Professional referrals bring in customers who already trust you, because someone they trust has vouched for you. Those are different starting points for the same relationship, and the referred one is easier on everyone involved.
The shift is not subtle. Once you have two or three OTs who refer to you consistently, plus a couple of home health agencies, plus one or two senior service provider groups where you're a known face, the texture of your business changes. The jobs come more steadily. They come with context. The work is more meaningful, and the income gets more predictable.
This isn't a secret. It's just slow. It takes months of showing up before the first OT calls you. It takes a year or two of consistent presence before the network is really working for you. Most installers don't have the patience, which is exactly why the installers who do end up dominating the markets they're in.
Start this month. Pick one hospital, one outpatient PT clinic, one home health agency, and one senior service provider group within a thirty-minute drive of where you work. Visit each of them, introduce yourself, leave materials, and follow up. Then do it again next month with a different set of four. In six months, you'll have built something that no amount of Facebook advertising could give you.
