Saying About Our Services!
House Washing Portland ME
We are so happy we went with Pristine Exterior Cleaning! Our house had been vacant for a year prior to us buying it, and the outside was covered in dirt and mildew. It looked brand new after the power wash! Tyler was great to work with and did a thorough house washing job.
Portland House Washing
Pristine cleaning used their soft touch system to clean the cedar shake siding on my house. It was blazing hot the day they came and despite the heat the cleaners were careful and thorough. They spent the whole day house washing in the blazing heat to expertly clean the siding, exterior windows and deck. The workers were respectful and friendly, they were great communicators and displayed impressive work ethic. Our house looks amazing! I was very pleased with the final results. Tyler and Riss were so friendly and helpful. I will recommend this company to anyone looking to have their house, window, and/or deck cleaned. Bravo!
House Washing in Portland ME
Pristine Exterior washed the outside of my house and applied a wood restoration product to follow. I am very happy with the house washing results. The exterior of the house has a very fresh clean look to it. The mold and mildew accumulated over time is gone. Tyler and his crew were very professional and easy to work with. I highly recommend if your house needs a “face lift” between paintings.

Frequently Asked House Washing Questions
Got Questions? We've Got Answers
Are You Insured?
While we try our best to respect and protect your home and windows. We understand that accidents can happen, and you as the homeowner should be protected. Luckily we’ve never had a claim (knock on wood) but we are fully insured just in case. We’d be happy to provide certificates of liability for personal liability and worker’s compensation upon request.
What Exactly Is Soft Washing?
Soft washing is the most effective way to kill living bacterial microorganisms that are infesting your home’s and/or business’s surfaces. It is more than cleaning. The products and methods we use not only clean stains, but also sanitize, penetrate, and eliminate the root of the issue. This method uses science and technology to address the microorganisms that grow on the exterior of your property. Homeowners can feel better having cleanings done without the damages normally associated with the blowing and blasting of pressure washing.
A soft wash system is an agricultural style sprayer that’s only use is to apply the soft washing solution. The solution does all the cleaning and absolutely no pressure is needed.
How Often Should I Wash My House, Roof, And Windows?
Most people get their windows washed once or twice per year, but this could vary based on environmental factors. If you prefer to keep your house looking fresh all year long, then yearly is a good choice.
Most people also get their house washed once per year; if you are concerned about algae spores and bacteria in the air, then getting your siding cleaned yearly is the best option.
Roof soft wash treatment results should last up to 6x longer than if just pressure washed alone. Keep in mind new growth is possible, but never re-growth because we will kill all the algae spores and bacteria that were previously growing. But over time, even with the 100% kill ratio and the buffering against new growth, it will happen. In most cases, and depending on environmental influences and amount of sunlight, you could see new growth in as little as 3 years, or it could be well over 5 years before having to deal with any of this again. Because roofs are so open and accessible to both rain and sun–two environmental factors that cause our formulations to continue cleaning your roof, we warrant them for 5 full years.
Does Exterior Cleaning Increase The Value Of My Property?
House washing in most cases will improve the value of your home. We often clean homes for people who plan on selling their house. By soft washing your home, you improve the curb appeal and the precoreved value. It creates a much better first impression for potential buyers.
Green algae and dirt build up is a sign that the house may not have been properly cared for and could have other hidden problems.
Are The Chemicals Safe For The Environment?
What is house washing?
House washing is a professional exterior cleaning service that uses low pressure methods to blast away dirt, grime, and other contaminants from the external surfaces of your house. The process typically starts with a thorough power washing or soft washing depending on the surface material. After power washing or soft washing, special attention is often given to window frames, skirting boards, fences, and other edges. Depending on the initial condition of the home, additional cleaning treatments are often applied such as mildew cleaners or anti-fungal solutions. Professional house washers may carry out their work with steam cleaning machines for greater precision and efficiency in removing dirt and plant growths like algae and moss from those hard-to-reach areas like gutters, and downpipes where traditional hand brushing can’t reach.

Is it safe to pressure wash vinyl siding?
Yes, pressure washing vinyl siding is generally safe if done correctly by a professional with the right equipment. Pressure washers can help remove dirt, grime, and mildew from your vinyl siding quickly and efficiently, but it is important to choose the correct pressure setting for your specific siding. A professional should always use a low-pressure setting to avoid damaging the surface of the vinyl. If you’re not sure which pressure setting you need, contact a local power washing service that specializes in cleaning residential exterior surfaces.
Professional power washers have years of experience using different types of cleaners and detergents on various materials such as wood, stucco, and brick – so they know exactly which products to use safely on vinyl without causing any damage or fading to the color or finish of your siding over time. In addition, many companies will apply an environmentally friendly solution after completion that helps protect against future weathering from sun exposure or rain.
Should I get my gutters cleaned by professionals?
Absolutely! Professional gutter cleaning is one of the most important steps in protecting your home from water damage and decay. As gutters accumulate debris, such as leaves and sticks over time, they can cause clogs that prevent proper drainage. This leads to moisture building up around the foundation of your house, causing structural issues and even mold growth inside your walls. Regularly cleaning out your gutters by a professional will help protect your home from these hazardous consequences.
Are pressure washing and soft washing the same thing?
No, pressure washing and soft washing are not the same things. Pressure washing utilizes high-pressure water to strip away dirt and grime from surfaces like concrete, wood, aluminum siding, and more. The high pressure of the water makes it ideal for cleaning areas with severe build-up or encrusted dirt and debris.
Soft washing is a much gentler method of cleaning that relies on a combination of low-pressure water along with biodegradable detergents or cleansers in order to loosen build-up without damaging any surrounding areas. This makes it an ideal option for delicate surfaces like roofs, stucco, painted walls, and concrete driveways.

Why should I hire a window cleaning service for my home?
Hiring a professional window cleaning service for your home is an excellent decision for many reasons. First, the professionals are experienced and reliable—they will be able to perform the job quickly and efficiently. Professional window cleaning services use specialized tools, solutions, and techniques to make sure that your windows get properly cleaned without any streaks or smudges. Something that you might not be able to do on your own with regular household materials. Additionally, professional cleaners have access to portable ladders and equipment like pole cleaners and extension poles which makes it much easier to reach those hard-to-reach areas of your windows.

What is roof washing?
Roof washing is a professional service that involves using specialized equipment and solutions to clean the surface of your roof. The process is designed to remove built-up dirt, debris, and algae/moss growth from the shingles and gutters of your home. Benefits of regular roof washing include better curb appeal, improved traction in wet or icy conditions, longer lasting roofs with fewer repairs needed over time, and enhanced protection against harmful elements such as UV rays. Professional roof washers use special cleaning solutions that are both low pressure so they won’t damage your shingles but also powerful enough to effectively rid them of any buildup on the surface including mildew growth or discoloration caused by tree sap or bird droppings. By having a professional come out and do a thorough inspection prior to beginning work you can ensure all areas are correctly cleaned while avoiding any potential issues in the future!
