How Do I Find the Best Plumbing Company for Major Repairs?
You find the best plumbing company for major repairs by checking their Oregon licenses, asking about big-job experience, getting a written estimate, and confirming they send their own crews.
A sewer line replacement or full repipe can cost you $5,000 to $15,000. The wrong plumber can turn that number into double fast. We see this happen all the time in Hillsboro, OR, where older homes from the 1970s and 1980s need serious plumbing work every year.
This guide gives you the exact steps to find the best plumbing company for major plumbing repairs in the Portland metro area. AllScope Plumbing and Construction, Inc. has helped Oregon homeowners with big plumbing projects for three generations.

What Counts as a Major Plumbing Repair?
Any job that costs over $3,000, takes multiple days, or changes your pipe layout is a major repair.
A dripping faucet or a clogged drain is a quick fix. You can call almost any local plumber for that. But these jobs need a higher level of screening:
Full house repiping
Sewer line replacement
Slab leak repair
Water heater replacement
These plumbing repairs cost $3,000 to $15,000 or more. In Hillsboro and Beaverton, homes near the Tualatin Valley sit on clay-heavy soil. Tree roots from Douglas firs and maples push into older water lines and sewer pipes. That creates leaks, low pressure, and even water damage inside your home. If your job fits this list, you need a specific type of plumber, not just any name from a search for plumber near me.
How Do You Screen a Plumbing Company Before You Hire Them for Major Repairs?
You follow seven steps that cover licensing, insurance, experience, pricing, crew, reviews, and permits.
Most homeowners skip straight to price. They call three plumbing companies, pick the cheapest quote, and hope for the best. That works for a small leak or a running toilet. But when you need a full repipe or a sewer line replacement, price alone tells you nothing. You need to screen the company the same way you would screen a contractor building onto your home. Here are the seven steps every homeowner in Hillsboro, OR, and the Portland metro should follow before signing anything.
Step 1: Does the Plumbing Company Have the Right Oregon Licenses?
Always check for two Oregon licenses before you talk about anything else. This is where most homeowners make their first mistake. They skip this step completely. Oregon requires every plumbing company to carry two licenses:
You can check any company's CCB license for free at Oregon CCB. Verify BCD licenses through the Oregon Building Codes Division. If the company dodges your question or can't give you both numbers, walk away. A licensed and insured company hands those over without hesitation.
Step 2: Can They Prove They Carry Insurance?
Ask for proof of general liability insurance and workers' compensation on the first call. Here's what each one does for you:
General liability insurance pays for damage to your home during the job. If a crew member hits a gas line or floods your basement, their insurance covers it.
Workers' compensation covers their crew if someone gets hurt on your property. Without it, you could face a lawsuit.
A reliable plumber will email you current insurance certificates the same day you ask. If they stall or say "we'll get to that," move on. This step takes five minutes and can save you thousands.
Step 3: Have They Actually Done Big Plumbing Jobs Before?
Ask how many large plumbing projects they finished in the last two years and request photos as proof.
Fixing a small leak under a kitchen sink and replacing a full sewer line are completely different jobs. Not every plumber near your area has the tools, crew size, or skills for major plumbing repairs. A lot of plumbing companies handle minor repairs and service calls all day but have never touched a $10,000 repipe.
Here's what to ask:
How many repiping or water line jobs have you finished this year?
Can you show me photos from past plumbing projects of this size?
Can I talk to a past homeowner who had similar work done?
AllScope Plumbing and Construction, Inc. brings three generations of hands-on plumbing and construction experience to every big job. Their team handles both trades under one roof, so they manage the full scope of repiping and plumbing design work without subbing anything out. Experienced plumbers who have done the work before get the job done right the first time.
Step 4: Will They Give You a Written Estimate With Every Cost Listed?
Only hire a plumber who puts every cost on paper: materials, labor, permits, timeline, and warranty.
If a plumber gives you one number on a phone call and says "that's the price," that's not an estimate. That's a guess. And most of the time, that guess goes higher once the work starts. You need a written breakdown so you can compare plumbing companies line by line.
A solid estimate should show:
Exact materials they plan to use (pipe type, fittings, plumbing fixtures)
Labor hours and crew size
Permit fees
Start date and expected finish date
Warranty on parts and labor
AllScope Plumbing and Construction, Inc. gives every homeowner transparent pricing with no hidden fees. You see the full picture before any work begins.
Step 5: Who Will Actually Show Up at Your Door?
Ask if they send their own trained crews or sub out big jobs to someone you've never met.
Some plumbing companies book the job, collect your deposit, and then send a random subcontractor. That person may not follow the same safety rules. They may not know the scope of your project. And if something goes sideways, the blame gets passed around.
For major plumbing repairs, you need to know three things: who enters your home, who manages the project, and who to call when something goes wrong. AllScope Plumbing and Construction, Inc. assigns one dedicated project manager to every job from start to final walkthrough. Their in-house, safety-trained crews handle the work directly. No middlemen. That gives you peace of mind and reliable service from day one.
Step 6: What Do Their Reviews Say About Big Jobs?
Search their customer reviews for homeowners who mention big jobs, not just small fixes.
A company might have 400 five-star reviews. But if every review covers a quick drain cleaning, you learn nothing about how they handle a full repipe or a water heater replacement.
Go to their Google Business Profile. Search for reviews that mention words like repiping, sewer line, water line, or water heater. Pay attention to these details:
Did crews show professionalism and arrived on time?
Did the company communicate clearly throughout the job?
Did they finish on schedule?
Did the homeowner mention clean job sites?
Consistently positive reviews about complex plumbing work show real service quality. Numerous negative reviews about missed deadlines or surprise charges tell you to keep looking. A reputable plumber should stand behind every job, big or small.
Step 7: Will They Pull Permits and Follow Oregon Code?
A professional plumber pulls all permits and follows the Oregon Plumbing Specialty Code without you asking.
Most major plumbing repairs in Oregon need a building permit. In Hillsboro, the Washington County building department handles those permits. The plumbing company should file the paperwork, pay the fee, and schedule the inspection for you. You should never chase this down yourself.
Oregon follows the Oregon Plumbing Specialty Code (OPSC), based on the 2021 Uniform Plumbing Code. If a company skips permits to save time, that unpermitted work creates real problems when you sell your home. A trustworthy plumber keeps your plumbing system up to code and helps protect your home value.

FAQs
What Questions Should I Ask Before I Hire a Plumber for a Big Job?

Find out if they back their labor with a warranty or written guarantees. Ask how they handle permits. A qualified plumber answers all of these quickly and efficiently on the first call.
Does a Plumbing Company Need a License in Oregon?
Yes. Every plumbing company needs a CCB license from the Construction Contractors Board. Each plumber on the crew also needs an individual plumbing license from the Oregon Building Codes Division. Always verify both before you hire a plumber for any size job.
Should I Get Multiple Quotes for a Major Plumbing Repair?
Yes. Get at least three quotes from different plumbing companies. Compare the scope of work, materials, labor, warranty terms, and timeline side by side. The cheapest quote is not always the right plumber for the job. Pick the company that provides the most honest and complete breakdown.
