How to Prevent Mildew in Your House Through a Valley Winter
Damp valley winters, steamy bathrooms and sweating windows are a recipe for mildew. Here is how to keep moisture down and know when to call a mold pro.
Read the guide →Insurance, background checks, supplies, crews, scope and how problems get fixed. The questions that separate a reliable cleaner from a risky one.
The most important questions to ask before hiring a house cleaner are about trust and accountability: are they insured, are their people background-checked, who will actually be in your home, what exactly is included, and what happens when something goes wrong. In Oregon, it also helps to know which registrations apply to a cleaning business and which do not. Here are the ten questions worth asking, and what a good answer sounds like.
A house cleaner has access to your home, your belongings and often your keys or door code. A good company will expect questions and answer them without hesitating. A vague answer to any of the questions below is worth taking seriously, whether you are hiring in Lebanon, Philomath or anywhere else.
Insurance protects you if something is damaged or someone is injured on the job. Ask what the policy covers and whether the company can show proof. In Oregon, a business with employees generally also needs workers' compensation coverage. The Oregon Department of Consumer and Business Services states that an employer with one or more subject workers must carry it, so it is fair to ask about that too.
Ask whether every person who enters your home has been background-checked, not just some of them, and whether the check happens before their first job. At Stellar Cleaning Solutions, every crew member is background-checked, insured and trained before they set foot on a job.
Consistency matters. A crew that knows your home knows where things go, which rooms matter most and how your pets react to a vacuum. Ask whether you will see the same people each visit and what happens when someone is out sick or on vacation.
If you will not be home, ask how entry is handled and who can use it. The arrangement should be agreed before the first visit and confirmed in writing.
Ask for the checklist. A standard clean usually covers kitchens, bathrooms, dusting, floors and trash. Inside appliances, baseboards, window tracks and inside cabinets are often deep-clean items or add-ons. Our post on deep cleaning vs regular cleaning lays out what each usually covers.
Some cleaners expect you to provide products and a vacuum. Others bring everything. If you have preferences, such as fragrance-free products or something safe for a specific pet, ask whether they can accommodate them. We bring our own supplies and equipment and use eco-friendly products as standard.
A reliable quote comes from seeing the home. Be cautious with a firm number given entirely over the phone, because it often changes on the day. Ask whether the estimate you approve is what you will be invoiced. Our post on what drives house cleaning cost explains the factors that go into a quote.
A good cleaner is upfront about limits. Large mold problems, biohazards, fire or flood damage and similar jobs belong to specialists. A company that says yes to everything may not be the right fit for anything.
Ask who you contact, how fast they respond and what happens next. The answer you want is a direct line to someone who can act, not a general inbox. Ask too how quality is checked. We use supervisor inspections so problems get caught by us, not reported by you.
Accidents can happen in any home. Ask how damage is reported, how quickly you will be told and how it is resolved. A company that is insured and has a clear process will have a straightforward answer.
This is one of the most common questions, and the answer surprises people. Based on the Oregon agencies' own guidance as of October 2026:
This is a summary, not legal advice. Rules change, so check the agencies' current guidance or talk to a professional if it matters to your decision.
We are an owner-operated business based in Corvallis, serving Lebanon, Philomath and the rest of the Willamette Valley and Central Oregon. Philomath is about ten minutes from our base and Lebanon an easy drive, so walkthroughs happen quickly. See our Lebanon and Philomath pages for local details.
Every crew member is background-checked, insured and trained. We bring our own supplies and eco-friendly products, keep the same crew on your home wherever possible, and supervisors inspect the work on a regular cycle. Learn more about our residential cleaning service, or our janitorial services if you manage a building. Bring this list of questions to ask before hiring a house cleaner to a free, no-obligation walkthrough and estimate, and we will answer every one.
Oregon does not require a Construction Contractors Board license for house cleaning, because the CCB licenses construction work. BOLI's Property Services Contractor License covers businesses employing workers for janitorial services, and its definition excludes residential house-cleaning. Business entities still register with the Secretary of State, and some cities require a local license. Check current agency guidance or talk to a professional for your situation.
Start by searching the company's name in the Oregon Secretary of State business registry to confirm it is registered and active. Then ask for proof of insurance, ask whether every cleaner is background-checked, and ask whether the business carries workers' compensation if it has employees. Read recent reviews, and be cautious of anyone unwilling to visit before quoting.
It depends on the company, so ask before you book. Many professional services, including ours, bring their own supplies and equipment, which means you do not need to stock anything. If you prefer specific products, or need something avoided because of allergies, pets or surfaces, say so up front and a good cleaner will work around it.
Tell the company as soon as you notice it, with photos and a short description. A reputable, insured cleaning company should have a clear process for reporting and resolving damage and should respond quickly. Ask about that process before you hire, so you know who to contact and what to expect if an accident ever happens.
Either can work well, but the questions are the same. Check insurance, background checks, registration and how problems are handled. A company typically offers backup coverage when someone is out and a consistent process for quality. An independent cleaner may offer a closer personal relationship. Choose whoever gives clear, confident answers to the questions in this guide.
