Taking over a job another contractor started: the best work you can get, or the worst

Why the first contractor really left

Understanding what went wrong tells you what you are walking into, and there are only a handful of real explanations:

• They ran out of money. Underpriced the job, spent the deposit on the previous project and could not fund materials. Often the work done is acceptable and the company simply collapsed.
• They were in over their head. Took on complexity beyond their experience and stalled at the hard part, which is usually exactly where you will start.
• The relationship broke down. Changes, arguments and unpaid invoices. Here the customer's own behavior deserves careful attention.
• They lost their license, insurance or crew. Sometimes discoverable in public records before you commit.
• The customer stopped paying. Ask directly, and ask for the payment history rather than the summary.

The first two are usually good jobs to take, with the right contract. The third and fifth require far more caution, because the pattern that ended the last relationship rarely originated with the last contractor alone.

The subcontractors and suppliers already involved

An abandoned project leaves a trail of people who were part of it and who may still have claims, materials or knowledge you need:

• Unpaid subcontractors and suppliers may hold lien rights against the property regardless of who owes them, which affects both the customer and your own payment security.
• Materials on site may not have been paid for, and using them can create a dispute. Confirm ownership before installing anything.
• Special-order items may exist in a supplier's warehouse under the old contractor's account, sometimes recoverable with the customer's help.
• The original subs know what is behind the walls, and a short conversation with the plumber or electrician who did the rough-in can save days of investigation.
• Reusing those subs is a judgment call. Their work may be fine, but their loyalty and their unpaid invoices both belong to the previous relationship.

Asking the customer for the full list of everyone who worked on the project, with contact details, should be part of the intake — not something discovered halfway through demolition.

The permit problem

A permit is issued to a specific contractor, and a project cannot simply continue under someone else's name. Depending on the jurisdiction, the path may involve the original contractor formally withdrawing, a new permit being issued, or a re-inspection of work that is already covered up.

• Call the building department before quoting. Ten minutes there prevents the most expensive surprise in this type of work.
• Expect inspection of concealed work. Opening walls to verify what was done is often required, and must be in the estimate.
• Assume code compliance is now yours. Whatever was built wrong becomes your responsibility once you take over.
• Document the condition before starting, in enough detail that nobody can attribute the earlier work to you.

The assessment is a paid service

Evaluating an abandoned project properly takes hours: reviewing plans, inspecting completed work, identifying deficiencies, checking permits and preparing a realistic completion scope. Doing that free is how companies lose entire days to projects they never take.

A paid assessment produces a written report covering what was done, what was done incorrectly, what must be redone, what is required to permit and inspect, and a completion estimate in phases. Customers in this situation almost never object to paying for it — they have just learned what unclear agreements cost.

Price it as a new project, not a remainder

The instinct is to quote "the rest of the work". That instinct is wrong, and it is what makes these jobs unprofitable:

• Include investigation time for figuring out what is behind the finished surfaces.
• Include correction of existing work, which is frequently larger than the remaining work.
• Include demolition of work that cannot be verified.
• Add a contingency and say so openly, because unknowns are the defining feature of the job.
• Price the coordination with inspectors, suppliers and sometimes attorneys.
• Refuse to warranty someone else's work, in writing, with a clear line between what you touched and what you did not.

What the contract must say

• A precise scope boundary — exactly what you are responsible for and what predates you.
• Warranty limited to your work, stated plainly and explained verbally as well.
• A payment schedule that stays ahead of your costs, because this customer has already lost money once.
• What happens when something unknown is discovered, including how change orders are approved and priced.
• A statement that the prior contractor is formally released, with documentation attached.
• Lien waivers from your suppliers and subcontractors, and clarity about any existing liens.

Managing a customer who has already been burned

This client will watch you far more closely than a normal customer, and their anxiety is earned. The remedy is over-communication, not reassurance:

• Daily updates in the first week, even when little has changed.
• Photograph everything, especially before anything is covered up.
• Hit the small promises exactly. Arriving at the stated time matters more here than anywhere else.
• Never criticize the previous contractor personally. Describe the condition, not the character.
• Deliver an early visible win in the first days, which does more for trust than any explanation.

When to walk away

• The previous contractor has not been formally terminated.
• There is active litigation and you would become a participant.
• The customer wants you to certify or warranty work you did not do.
• The budget remaining is clearly insufficient and the customer will not reduce scope.
• The customer describes every past vendor as a fraud. You will be next in that list.
• The structure or systems are unsafe and the customer refuses to address it.

Declining these clearly and kindly is a business skill. "I am not the right company for this situation" is a complete sentence, and it saves months.

Why the good ones are worth it

Round numbers for a completion job done properly:

• Paid assessment: $850, which covers the day spent evaluating and reporting.
• Completion contract: $46,000, including $9,000 of correction work the customer did not know was needed.
• Margin ten points above a typical competitive bid, because there was no competitive bid.
• Referral value: customers rescued from a failed project talk about it for years.

These jobs are won on availability and trust rather than price, which is exactly the kind of work every service company says it wants — provided the dangerous ones were filtered out at the door.

Where to start

Write a one-page intake for takeover calls with the six qualifying questions, set a price for the assessment, and prepare a contract addendum that draws a hard boundary around your scope and warranty. Then call your building department once and learn exactly how permit transfers work in your jurisdiction. With those three things ready, the abandoned-project call stops being a risk you weigh case by case and becomes one of the most profitable, least competitive sources of work available to a service company.

Frequently asked questions

Should a contractor finish work another contractor started?

Often yes, because these customers are motivated, are past comparison shopping and rarely make it about price, which means margins are usually better than on competitively bid work. The danger is that once you touch the project, customers and inspectors stop distinguishing your work from what came before it. Before visiting, establish whether the previous contractor has been formally terminated or released, what the written contract says, how much has been paid and for what, who pulled the permit, whether any claim, lien or dispute is active, and whether the materials on site were actually paid for. If the previous contractor has not been formally released, the correct answer is that you cannot start, because two contractors with claims to the same job is a legal problem rather than a scheduling one.

Who is responsible for the permit when a new contractor takes over?

A permit is issued to a specific contractor, so a project generally cannot continue under someone else's name. Depending on the jurisdiction, the path may require the original contractor to formally withdraw, a new permit to be issued, or re-inspection of work that has already been covered. The practical step is to call the building department before quoting, because ten minutes there prevents the most expensive surprise in this type of work. Expect that concealed work may have to be opened for verification, which belongs in the estimate, and assume that code compliance becomes your responsibility once you take the project over. Documenting the existing condition thoroughly, with photographs, before starting anything is essential.

Should you warranty work done by the previous contractor?

No, and the limitation has to be written into the contract and explained verbally as well, because it is the single most likely source of a later dispute. The contract should draw a precise scope boundary between what you are responsible for and what predates you, limit the warranty to your own work, set a payment schedule that stays ahead of your costs given that this customer has already lost money once, define how unknown conditions are handled and priced as change orders, attach documentation showing the prior contractor was formally released, and address lien waivers from your suppliers and subcontractors along with any existing liens. Pricing should also treat the project as new work rather than as a remainder, including investigation time, correction of existing work and an openly stated contingency.
