For Contractors and Developers

If you’re a contractor, you already know the job doesn’t end when the build is done. Not when owners are slow to pay, deadlines shift, or you’re suddenly being blamed for things outside your control. Disputes can drag on and cost you more than money. That’s where we step in.

We work with general contractors and subcontractors to resolve issues like unpaid invoices, scope disputes, holdbacks, and performance claims. But good protection starts before the problems do, with solid contracts and a clear billing strategy that’s actually enforceable. If your paperwork is in order, your chances of getting paid on time and in full go way up.

When payments stop, we act fast. Construction liens are powerful, but they’re time-sensitive and technical. We help contractors file, preserve, and enforce liens properly, and deal with trust claims or disputes head-on. You’ve already done the hard work building the project. Let’s make sure you’re paid for it, without delays or excuses.

FAQ for Contractors and Developers

Can I be removed from a project without cause?

If you have a contract in place, the other party can’t just remove you without consequences. Whether they’ve issued a notice of termination or are trying to push you out informally, it’s important to get legal advice before responding.

What are my rights if I’m being blamed for delays or defects?

Contractors are often unfairly blamed for issues that weren’t their fault. We’ll look at the contract terms, site records, and correspondence to assess liability and push back if needed. 

What is a construction lien, and how do I file one?

A construction lien is a way to secure payment by registering your claim against the property. But deadlines are tight and mistakes can void your rights — we can handle it for you from start to finish. 

What if the owner keeps changing the scope but won’t sign change orders?

Unwritten change orders are a common problem. You may still be entitled to compensation — especially if there’s evidence they accepted the changes. Don’t let it slide.

Can I recover costs caused by delays outside my control?

Maybe. It depends on your contract and the reason for the delay. If you lost time or money due to the owner or another trade, you may have a valid claim for damages.

What’s the first step if I think I have a legal issue?

 Reach out — ideally before you respond in writing or take any action on-site. A quick conversation can help you avoid mistakes that weaken your position later. 

What are your fees ?

Our fees typically start at $320/hr +HST, one hour minimum. Please contact us to discuss different payment arrangements we offer. Our goal is to add value to your business, not to overbill you.  

For Property Owners

As a property owner or developer, you’re managing a lot deadlines, budgets, and expectations. When a project runs into trouble, it can spiral quickly: disputes over delays, extra charges, or workmanship can stall progress and turn into costly headaches. We help owners navigate construction disputes with contractors, trades, and consultants without getting buried in finger-pointing.

If a contractor has filed a lien, we can move to have it removed, especially if it was filed improperly or without cause.

We also enforce your rights under the contract, whether it’s holding someone accountable for missed deadlines or defending against inflated claims. You’ve invested in the project.

We’ll make sure that investment is protected and that your legal strategy supports getting the job done. 


FAQ for Property Owners

What can I do if the contractor isn’t meeting deadlines?

If the project is behind schedule, and it’s not due to your own actions or unavoidable delays, you may have grounds to hold the contractor accountable — including for financial losses. It starts with a review of your contract.

The work isn’t up to standard. Can I withhold payment?

Yes — but only if you do it the right way. You’ll need documentation, and you risk triggering a lien if it’s done improperly. We can help you protect your position and make sure any deficiencies are addressed.

A contractor just filed a lien on my property. What now?

A lien can delay financing, sales, or project progress. We’ll assess whether the lien is valid, negotiate a resolution, or move to have it discharged if it’s improper or inflated.

The contractor is demanding more money than agreed. What are my rights?

This happens often, especially with vague or undocumented change orders. If the extra charges aren’t backed up by the contract or written approval, you may not be obligated to pay them.

Can I fire a contractor mid-project?

Yes, but only in certain situations — and not without risk. Wrongful termination can lead to costly legal claims. Talk to us before making that call.

Should I get legal advice before responding to a contractor’s threat or demand?

 Yes. A single email or misstep can weaken your position. A quick legal review upfront often prevents bigger problems down the line.

What are your fees?

 Our fees typically start at $320/hr +HST, one hour minimum. Please contact us to discuss different payment arrangements we offer. Our goal is to add value to your business, not to overbill you.
