How to Choose an Exterior Cleaning Company in Charleston

Anyone can buy a pressure washer and put a magnet on a truck door. The real gap between companies is not the gear. It is the method, who answers for the work, and whether the crew is insured if something goes wrong. Here is a checklist you can use on any company, including us.

What should you ask before you hire?

1. What method will you use on my siding, and why? A good answer names your siding and explains the plan. Vinyl, fiber cement, stucco, brick, and wood all act differently. If the answer is the same for every house, they clean by habit, not by surface.
2. Are you insured, and for how much? Do not stop at yes. Ask for the amount and a certificate of insurance you can read. The number matters. Your house is worth more than a small policy covers.
3. How will you protect my plants? You want to hear that they wet plants before and rinse them after. They should cover fixtures and control where runoff goes. Silence here usually means it does not happen.
4. Who is actually doing the work? Is it their own crew, a subcontractor, or day labor? This matters for quality and for insurance. Coverage does not always follow a subcontractor onto your property.
5. What happens if something gets damaged? Ask them to walk you through it. A clear process, an insurer, and a way to file a claim is a real answer. Being told it never happens is not.

Five questions, one phone call. How a company answers tells you more than any ad.

What does liability insurance cover?

Liability insurance covers damage the company causes to your property while working. In this trade, that means a cracked window, water forced behind siding, dead plants, an etched finish, a stained deck, or spray damage to the house next door.

Here is the part people miss. If a company with no insurance damages your house, no one else pays for it. You can file on your own homeowners policy, which may raise your rate. Or you can sue a small company that may have nothing to collect. Either way, you pay. Hiring someone without insurance does not remove the risk. It moves the risk onto you.

For the record, TrueWash is licensed and $2 million insured. Ask any company you are thinking about for the same details. Ask for the certificate, not just a spoken answer.

What red flags mean you should walk away?

These are not about any one company. They are habits that show up across the trade:

• Door knocking with a price that is good for today only.
• Will not put the job in writing.
• No certificate of insurance.
• One high pressure method for every surface.
• A price far below every other quote.
• A large cash deposit up front.
• No local address or local track record.
• Reviews that talk about a different area.

The high pressure for everything flag matters most. It is the most common cause of costly damage. Siding, roofs, and fine woods like Ipe and garapa should never see high pressure. A company that treats a hardwood deck like a concrete driveway leaves marks that only sanding can fix.

What green flags are worth paying for?

• A method for each surface, explained in plain words.
• A written list of what is and is not included.
• Proof of insurance, sent without you chasing it.
• Real photos of local homes, not stock photos.
• References you can really call.
• Before and after photos sent when the job is done.
• A clear answer about who will be at your house.
• Willing to say a job is not right for them.

That last one is overlooked. Some companies will tell you a surface needs a different approach. Some will turn down a job that is not a good fit. A company like that is not just chasing the bill.

Why does the cheapest quote often mean high pressure?

Price tells you something about method. A soft wash takes time. The solution has to sit and work. The rinse has to be thorough. Plants get wet before and rinsed after. Someone has to move slowly enough to do it right. Blasting a wall with high pressure is faster. Faster means the job can be priced lower.

So when one quote comes in far below the rest, it is usually one of three things. The company is not insured. The method is rougher than your surfaces should take. Or the job leaves out work you thought was included. Any of those can be fine if you know about it. The problem is that a low number alone does not tell you which one it is. Ask.

Hiring an exterior cleaning company FAQ

What is the most important question to ask?

Ask what method they will use on your siding, and why. A company that names your siding and gives a reason has looked at your house. A company that uses the same high pressure approach on every surface has not.

How do I check that a company is insured?

Ask for a certificate of insurance. Check that it is current and lists a real coverage amount. A photo of a policy card is not the same thing. Any real company will send a certificate right away. TrueWash is licensed and $2 million insured.

What does liability insurance actually cover?

It covers damage the company causes to your property while working. That includes a broken window, water forced into a wall, ruined plants, or damaged siding. If the company has no insurance, you are left with your own homeowners policy or a lawsuit. Both cost you.

Is a much cheaper quote a bad sign?

Often, yes. A quote far below everyone else usually means one of three things. There is no insurance, the method is faster and rougher, or the job leaves out work you thought was included. Ask which one it is before you decide.

What should be in writing before work starts?

The surfaces included and not included, the method for each one, and how your plants will be protected. Also who is doing the work, and what happens if something is damaged. If a company will not put the job in writing, any later disagreement is on you to prove.

How should I handle a door knocker with same day pricing?

Slow it down. Ask for the company name, proof of insurance, and a written quote by email. Then decide later. Real companies are fine with that. A push to sign today is a tactic, not a real deadline.
