General Contractor Troubleshooting: Common Problems and How to Fix Them

General Contractor Troubleshooting: Common Problems and How to Fix Them

A subcontractor can file a mechanics lien against your home even if you paid your general contractor in full. In California, you have just 20 days from the start of work to protect yourself with a Preliminary Notice response, and most Los Angeles homeowners never find out until the lien is already recorded against their property. This guide walks through the real problems that surface after the drywall is up: liens, silent contractors, budget overruns, failed inspections, and waterproofing failures that quietly void insurance claims. You’ll learn what paperwork to keep, what escalation to follow, and which problems are worth fighting versus paying to fix and moving on.

Quick Answer

If you’re having problems with a general contractor, the first step is to stop work, document everything in writing, and request a written itemized accounting of what has been paid and what remains. In California, you have specific legal deadlines for responding to mechanics liens and filing complaints with the Contractors State License Board (CSLB), so acting within 20 days of any notice matters.

Mechanics Liens: What They Are and How to Respond in California

In California, anyone who supplies labor or materials to your project has the right to place a lien on your property if they’re not paid. That includes subcontractors, material suppliers, and even equipment rental companies. They don’t need your permission, and they don’t need to have a contract directly with you. A lien against your Los Angeles property can block a sale, force a refinance into limbo, or ultimately lead to foreclosure if ignored.

The clock starts the moment work begins. In California, if you did not file a Preliminary Notice yourself, you may still receive one from a subcontractor or supplier. That notice is your signal that this party has the right to lien your property. You should respond by confirming in writing that the general contractor is responsible for payment, and request a conditional and unconditional waiver of lien from every party on the job at each payment milestone.

Step-by-Step Response to a Mechanics Lien

1. Do not ignore it. A recorded mechanics lien in California must be enforced within 90 days, or it becomes void. But before that, it sits on your title.
2. Read the lien carefully. Confirm the name of the claimant, the amount claimed, the dates of work, and the property description. Errors here can make the lien invalid.
3. Contact the claimant in writing. Ask for a full accounting of labor and materials. Request signed lien waivers from prior payments and the contract that authorizes their work.
4. Demand your GC resolve it. Send a certified letter to your general contractor demanding they pay or dispute the lien within 10 business days. Keep the receipt.
5. If unresolved, file a complaint with the CSLB. The Contractors State License Board investigates payment disputes and can suspend a license for failure to pay subcontractors.
6. Consider a bond to remove the lien. You can post a mechanics lien release bond for 125% of the claimed amount to clear the lien from your title while the dispute plays out.

Here is the part most homeowners miss: a lien can be valid even when you are not at fault. If your GC collected your final payment and never paid the tile installer, the installer’s lien is against your property, not the GC’s. Your argument is with the GC, but the lien is on your house. In our experience working on home renovations in Los Angeles, the homeowners who avoid this are the ones who collect signed lien waivers at every single payment point.

What to Do When Your General Contractor Goes Silent Mid-Project

A general contractor who stops answering calls or texts mid-project is not just frustrating. It is a specific breach of the duty of good faith that California courts recognize in construction contracts. The fix is not to send angry voicemails. It is to create a paper trail that proves you tried to resolve the issue before taking legal action.

Start with written notice. Send an email and a certified letter that states the specific dates your GC stopped responding, the work that remains incomplete, and a deadline for a written response. In Los Angeles, where a half-finished bathroom remodel can sit for weeks while a contractor juggles other jobs, a documented deadline is your primary leverage. Ask for a written completion schedule and a revised payment schedule tied to specific milestones.

If seven days pass with no response, escalate to the CSLB. Filing a complaint is free, and the CSLB will contact the contractor’s bond company. Most licensed contractors respond quickly when their bond is threatened. If the contractor is unlicensed, you have additional civil remedies and may be entitled to full recovery of what you paid.

In practical terms, the contractors who ghost are often the ones who underbid the job and ran out of money. They disappear because they cannot afford to finish. That is why a written price before work starts matters so much. It is not just clarity. It is your early warning signal that the contractor actually priced the job correctly. When a written price is committed before a tool is picked up, a contractor cannot return two weeks later with a story about unexpected costs.

Budget Overruns: Legitimate Scope Creep or Bait-and-Switch?

There are two kinds of budget overruns on a remodel: the ones you can see coming and the ones you can’t. The first are legitimate. You open a wall and find knob-and-tube wiring that was not on the plans. You discover rotten subfloor under the old tile. These are real conditions that could not be known before demolition. They should be handled with a written change order that you approve before the extra work begins.

The second kind is a bait-and-switch: a low initial estimate that climbs as the project moves forward. The contractor “discovers” problems that were visible before the estimate was written. Or the allowances for materials were set unrealistically low. Or the contract is vague enough that basic items like “trim work” or “tile setting” become extras later.

Here is how to tell the difference. A legitimate change order is specific: what was found, why it was not discoverable, what the extra work costs, and how long it adds to the schedule. A bait-and-switch is vague: “we need to adjust for materials” or “labor is running higher than expected” with no line-item explanation. In Los Angeles, where remodeling costs run higher than the national average, the spread between a legitimate change order and a padding tactic can be tens of thousands of dollars.

The best protection is a written price before any work starts. Not an estimate. A written price that says what is included, what is excluded, and what the material allowances are. That document is the reference point when a change order shows up. If the change order contradicts the written price, you have grounds to push back.

The Paper Trail That Wins Small Claims and Arbitration Cases

If a contractor dispute ends up in small claims court or arbitration, the decision rarely comes down to who is more persuasive. It comes down to who has the better paper trail. The side with dated photos, written change orders, and payment records wins almost every time. The side with a pile of text messages and a vague memory loses.

Small claims in California caps at $12,500 for individuals. That covers a lot of contractor disputes. But you have to prove damages. Here is the minimum paper trail you should keep from day one of any project, whether it is a bathroom remodel in Silver Lake or a whole-home renovation in Brentwood:

• The signed contract with a clear scope of work, a payment schedule, and a completion date.
• The written price. Not an estimate, not an email summary. A written line-item price you approved.
• Every change order signed by both parties before the extra work was done.
• Every payment record with the date, the amount, and what phase of work it paid for.
• Lien waivers from every subcontractor and supplier on the job, signed at each payment.
• Dated photos of the work at each stage, especially before and after any dispute.
• Written communication about delays, problems, or changes. Texts count, but emails and certified letters carry more weight.

Most homeowners in Los Angeles don’t have half of this. They paid in cash, they never got lien waivers, and their change orders were verbal. That is exactly the position a bad contractor wants you in. When you ask for these records up front and the contractor hesitates, that hesitation is information.

How Photo Documentation and Written Price Confirmations Protect You

Photos are the cheapest legal evidence you can produce, and most people take them in the wrong direction. They photograph the finished tile but not the waterproofing underneath. They photograph the new vanity but not the plumbing rough-in behind it. The photos that matter are the ones that show the work that gets covered up, because that is where disputes live.

Take photos before every phase closes. Before drywall goes up, photograph the framing, the electrical, the plumbing, the insulation. Before tile goes down, photograph the shower pan and the waterproofing membrane. Before flooring is installed, photograph the subfloor. These are the photos you’ll need if something fails later and the contractor says the damage was pre-existing.

Written price confirmations work the same way. Before each phase begins, send a short email confirming what is included in that phase, when the work will start, and what it costs. It does not need to be long. “Confirming we are starting the shower waterproofing on Monday. This includes the pan liner, the curb, and the wall membrane. Price is $2,400 as approved in the written estimate.” That single message is worth more than a year of arguments if the contractor later claims waterproofing was a separate charge.

In Los Angeles, where a water damage claim can be denied because the waterproofing was not installed correctly, these photos and confirmations are what protect you when the insurance adjuster asks what happened. And the contractor who operates this way on purpose, with photo updates before and after each phase and a written price before each phase starts, is a contractor who has systems, not excuses.

Failed Inspections: Root Causes and Getting Back on Track

A failed inspection is not a catastrophe. It is a correction notice. What turns it into a catastrophe is a contractor who hides the failure, argues with the inspector, or re-attempts the same work without addressing the cited deficiency. The right response to a failed inspection is specific, fast, and documented.

1. Get the correction notice in writing. Ask for a copy from your contractor or from the Los Angeles Department of Building and Safety. The notice will list exactly what failed and what code section applies.
2. Ask the contractor for a written corrective plan. The plan should state what work will be redone, who will do it, how long it will take, and whether there is any added cost.
3. Confirm the reinspection is scheduled. In Los Angeles, reinspection fees apply, and the reinspection must be requested by the permit holder. Make sure your contractor is still on the permit.
4. Photograph the corrected work before the reinspection. This is your record that the deficiency was addressed.

Most failed inspections in Los Angeles fall into a handful of categories: improper waterproofing in wet areas, electrical work that does not meet current code, insufficient structural support, or improper venting. These are not cosmetic issues. They are the reasons home renovation projects in Los Angeles require permits in the first place. A contractor who suggests you skip the permit to save money is also asking you to skip the inspection that would catch their substandard work. That trade is never worth it.

Waterproofing Failures and Homeowner’s Insurance Claims

The most expensive contractor problem Los Angeles homeowners face is the one that does not show up for six months. A shower pan that was not properly sloped. A tile floor with no waterproofing membrane underneath. A window flashed incorrectly during a renovation. The work looks fine on the final walkthrough. Then the water finds a way through, and the damage shows up as mold in a closet, bubbling paint on a ceiling below, or a soft spot in the subfloor.

When you file a homeowner’s insurance claim for water damage, the adjuster’s first question is whether the damage came from a covered peril like a burst pipe or a sudden leak, or from faulty workmanship and long-term seepage. Faulty workmanship is generally excluded from standard homeowner’s policies. If the waterproofing was done incorrectly, the insurance company may deny the claim and point you back to the contractor, who is now six months gone.

That is why written price confirmations and phase photos matter for more than just disputes. They are the evidence you need to show the insurance company what was installed, when it was installed, and what it looked like before it was covered up. Without that, the claim becomes your word against a denied payout.

This is also where the 365-Day Done Right Promise matters in a practical sense. A contractor who stands behind waterproofing and installation work for a full year after the project closes is saying that the work was done to a standard that holds up. A contractor who disappears after the final check is saying something else entirely.

Common Mistakes to Avoid

• Ignoring the Preliminary Notice. In California, the 20-day Preliminary Notice is your first warning that a subcontractor or supplier can lien your property. Ignoring it doesn’t make it go away.
• Paying in cash without a receipt. Cash payments with no paper trail leave you with no proof of payment when a lien is filed or a dispute goes to court.
• Accepting verbal change orders. A verbal change order is a gift to a contractor who later wants to inflate the bill. If it isn’t written and signed, it didn’t happen.
• Skipping permits to save money. Unpermitted work in Los Angeles can come up at resale, can void insurance coverage, and gives a bad contractor license to cut corners.
• Hiring an unlicensed contractor. In California, a contractor’s license is not a formality. It is the legal requirement, and unlicensed work leaves you with limited recourse when something goes wrong.
• Taking the lowest bid without comparing scope. In Los Angeles, a bid that is 30% below the next two is not a bargain. It is a contractor who left something out of the price, and you’ll pay for it in change orders.
• Not collecting lien waivers. Every payment should come with signed waivers from every subcontractor and supplier on the job. Skipping this is how a paid-in-full homeowner still ends up with a mechanics lien.

When to Call a Professional

Some contractor problems are worth handling yourself. A delayed start date, a small miscommunication, a minor change order question, those are email-and-a-phone-call situations. But when you’re facing a recorded mechanics lien, a failed inspection that the contractor won’t address, a water leak that started after the remodel, or a contractor who has been silent for two weeks, you need professional help. A construction attorney or a licensed contractor who can assess the work in writing is worth the cost. For General Contractor Warning Signs Every Homeowner Should Know, see our earlier guide.

Frequently Asked Questions

The Bottom Line

Most general contractor problems share a common root: the homeowner did not have a written price, a paper trail, or a clear escalation path when things went wrong. The mechanics lien that blindsides you, the silent contractor, the budget that doubles, the waterproofing failure that voids your insurance, all of them are easier to prevent than to fix after the fact. In Los Angeles, where remodeling costs run high and the stakes are your biggest asset, the smartest move is to choose a contractor who puts the price in writing before work starts, documents every phase with photos, and stands behind the work for a full year. If you’re planning a project or untangling a mess from a previous contractor, Sawyer Remodeling can help. We’ve been serving Los Angeles since 2005, and we offer free estimates. Call (254) 272-5876.
