A single maintenance relationship with a plant or warehouse can keep a crew busy on weekdays all year, with little of the seasonal swing that residential work brings. Cambridge has several mapped business parks, and the facilities inside them need electricians, heating and cooling technicians, plumbers, roofers, cleaners and snow crews. Winning that work is slower and more personal than residential marketing, but the payoff is steadier.
Understand what the buyer is afraid of
A facility manager's biggest fear is downtime, closely followed by a safety incident involving a contractor. Price matters, but much less than you'd think. When a line stops because a panel trips or a roof leaks onto equipment, the cost of a slow vendor dwarfs any saving on the hourly rate.
So your pitch isn't "we're cheaper". It's "we're easy to approve, we answer, and we turn up prepared". Everything below is about proving those three things.
Step one: get your paperwork in order
Before you contact anyone, assemble the documents a manager will ask for. If you send them within an hour of being asked, you stand out.
- Proof of liability insurance, with the coverage amount clearly stated.
- A current WSIB clearance certificate. WSIB issues these, and many companies won't let a contractor on site without one.
- Your trade registration or licence, where it applies. Fuels work in Ontario involves TSSA registration, and electrical contracting for others involves an ESA licence. Confirm what applies to you with the regulator directly; we don't give compliance advice.
- Your safety policy and a summary of crew training.
- A one-page capability sheet: services, response times, typical sites, owner's direct number.
Keep all of it in one folder, ready to send as a single email.
Step two: build a short, realistic target list
Aim for 30 to 60 businesses you can actually serve well, not hundreds.
The City of Cambridge maps several business parks, including the Cambridge Business Park and the Eastern Industrial Park, and these are a natural starting point. Drive through them, note the companies and the types of buildings, and check each one online.
For each business, note:
- what they do and roughly how large the site is;
- whether the building looks like it needs your service, for example a large flat roof, extensive loading docks or significant electrical load;
- who handles facilities, if you can find out;
- any connection you already have, such as an employee who's a residential customer.
Rank the list. Your first outreach should go to the 15 sites where you're the most obvious fit.
Step three: the first contact
Make the first contact short, specific and from the owner.
A letter or email might follow this pattern, adapted to your trade:
Hi [Name], I run [Business name], a [trade] company based in [area of Cambridge], a few minutes from [their site area]. We look after [type of work] for [type of facility]. If your current vendor is ever slow to respond, we'd be glad to help. I've attached our insurance, WSIB clearance and a one-page summary so you have them on file. My direct number is [number]. [Your name]
Notice what it doesn't do: it doesn't criticise their current vendor, offer a discount or ask for a meeting straight away. It makes you easy to remember and easy to approve.
Step four: follow up patiently
Most replies come after the second or third contact, often months after the first. A reasonable rhythm:
| When | What |
|---|---|
| Week 0 | First letter or email with documents |
| Week 3 | Short follow-up, perhaps a seasonal note such as roof checks before winter |
| Month 3 | A useful tip or a reminder before a known busy period |
| Month 6 | A brief check-in: "still here if you need us" |
Keep a simple tracker: who you contacted, when, what they said and the next date to follow up. A spreadsheet is enough.
Step five: make the first job count
When the call comes, it's usually urgent and usually a test. Treat it as an audition.
- Turn up when you said you would, with the right equipment.
- Follow site safety rules without being asked.
- Send a clear written summary of what you did, what you found and what you'd recommend, with photos.
- Invoice promptly and accurately.
A manager who gets that experience once will call again. After two or three good jobs, ask whether they'd consider a scheduled maintenance agreement.
Price the work so it stays worth having
Recurring commercial work only helps if it pays. Before you quote a maintenance agreement, work out what each visit really costs you: travel from your base, time on site including safety briefings and sign-in, parts, and the paperwork the client expects afterwards.
Industrial sites often have slower payment terms than homeowners, sometimes 30 to 60 days. Factor that into your cash flow before taking on several contracts at once. A contract that keeps the crew busy but leaves you waiting two months for payment can strain a small business.
A simple rule: if a scheduled visit doesn't clear the same profit per hour as your residential work, either the price or the scope needs to change. Our lead budget guide shows how to calculate profit per job, and the same method applies here.
Make sure you can be found online
Even when your outreach is personal, facility managers will look you up. Your website should have a page written for them, separate from your residential pages, covering commercial services, response times, insurance and safety, and the types of sites you work on. Our industrial-parks service and website service cover how we build those pages.
When to say no
Not every industrial opportunity is worth taking. If a site wants response times your crew can't meet, payment terms your cash flow can't carry, or a scope that pulls you away from profitable residential work in your peak season, it's fine to decline politely and stay in touch. A clear no protects your reputation better than a stretched yes.
Common mistakes
- Sending a residential flyer. Commercial buyers want different information.
- Overpromising response times. Missing one urgent call can end the relationship.
- Stopping after one attempt. Persistence, done politely, is most of the work.
- Ignoring smaller sites. A modest warehouse that calls you every month is worth more than a large plant that calls once a year.

Frequently asked questions
How do I find out who manages a facility?
Start with the company's website and LinkedIn, then call the main line and ask who handles maintenance or facilities. Be polite and brief; reception staff often know exactly who you need.
Should I lower my prices to get in the door?
Rarely. Facility managers care more about reliability and paperwork than a small discount, and a low starting price is hard to raise later. Offer a trial job at your normal rate instead.
What if a site already has a vendor?
Most do. Your goal is to be the obvious second choice when the current vendor is slow or unavailable. Those overflow jobs are often how a long-term relationship starts.
Do I need special insurance for industrial sites?
Requirements vary by company. Ask each prospect for their vendor requirements and talk to your insurance broker. We don't give insurance or compliance advice.
