Vinyl Siding Washing and Restoration

Dirty siding makes an entire home look older and less cared for, even when everything else is in great shape. Over time, vinyl and exterior siding collect dirt, pollen, water streaks, and organic growth that shows up as green staining or dark patches in shaded areas. Siding cleaning is one of the fastest ways to refresh curb appeal and make the exterior look bright again.
We provide professional siding cleaning using safer, surface-appropriate methods that remove buildup without damaging the finish. If you want a fast quote, send your city and a couple photos of the siding areas you want cleaned.

What’s Included in Our Siding Cleaning

Siding cleaning is quoted based on home size, siding type, and how much buildup is present. Most jobs focus on the most visible elevations and problem areas, with full exterior options available.

What’s commonly included:

Exterior siding wash using a method matched to the material
Targeted treatment for green staining and organic buildup where needed
Rinse and finish that leaves siding noticeably cleaner
Attention to corners, edges, and common streak zones

Optional add-ons (quoted as needed):

Extra-heavy organic growth treatment areas
Additional exterior detail work around trim and accents
Bundled exterior services for a full curb appeal refresh

If there’s a side of the home that stays shaded and grows faster, mention it when requesting your quote.

What We Remove

Siding cleaning is designed to remove the common buildup that dulls your exterior and causes streaking or discoloration

We commonly remove:

Dirt and dust buildup
Pollen and seasonal residue
Green algae staining (common on shaded sides)
Mold and mildew-type staining on exterior surfaces
Water streaks and runoff marks
General grime that makes siding look faded

If you’re dealing with heavier organic growth, soft washing may be the best option for longer-lasting results

Siding Cleaning vs Pressure Washing

High pressure isn’t always the right choice for siding. Vinyl siding can flex, seams can force water behind panels, and older surfaces can be more sensitive. That’s why many siding cleans are best handled with lower pressure methods and the right approach for organic growth.

Siding cleaning is best for:

Vinyl siding and exterior walls
Areas where algae or green staining is the issue
Cleaning that protects the surface finish

For general exterior wall cleaning options, see house washing.

Pressure washing is best for:

Concrete driveways and walkways
Patios and pool decks
Hard surfaces that can handle higher pressure

If your goal is a complete exterior refresh, many customers combine siding cleaning with pressure washing for the driveway and patio.

Best Siding Types and Areas We Clean

We clean a wide range of exterior surfaces and siding types, using the method that matches the material and condition.

Common siding and exterior areas:

Vinyl siding
Painted siding and trim (depending on condition)
Exterior walls with algae staining or streaking
Front elevation and garage front (high-visibility areas)
Corners, seams, and areas under trees
Entry areas and exterior accents

If you’re not sure what siding you have or what method is best, photos make it easy for us to recommend the right approach.

Siding Cleaning FAQs

Is siding cleaning safe for vinyl siding?

Yes, when the right method is used. We match the approach to the surface and condition.

Will this remove green staining?

In many cases, yes. For heavier organic growth, soft washing is often the best option.

Do you use high pressure on siding?

Not by default. We use surface-appropriate methods designed to clean without damage.

How long do results last?

It depends on shade, exposure, and weather. Shaded sides may grow faster and need more frequent cleaning.

Can you clean painted siding?

Sometimes, depending on paint condition. Send photos for the best recommendation.

Do you clean soffits and fascia too?

That can be added depending on what you need. Mention it when requesting a quote.

Can I bundle siding cleaning with other services?

Yes. Pressure washing, gutters, and detailing are common add-ons.

How do I get the fastest quote?

Send your city and a couple photos of the siding areas you want cleaned.

 Trustindex verifies that the original source of the review is Google. I think this is our 5th year in a row using Next Gen and this crew is just incredible. Professional and clean they get the job done and clean up after themselves like they weren’t even there. My windows are so clean I can’t even tell they are there right now. They also cleaned out our gutters/ power washed our siding and did a certified spider spray which is necessary this close to Lake Ontario. Thanks for all the hard work and we will definitely be calling you again next time!

 Trustindex verifies that the original source of the review is Google. Ben, Mike and the rest of the NXT GEN team just did an incredible job cleaning the windows both inside and out, screens(!!!) as well as washing the siding on our 2 storey house.  I was blown away by their professionalism and attention to little details like cleaning screen troughs. Great pricing too. After using "Paradisus" for the past few years we now say farewell "P" and hello NXT GEN. Thanks again.

 Trustindex verifies that the original source of the review is Google. My gutters which are too high for my confort level on a ladder were blocked. After an attempt at using a power washer attachment with no success I put in a request on Next Gen's website. Andrew replied withing minutes. That was a Thursday about 4pm. He was there for a quote the next morning on his way to another job. That was Friday. I was booked for the following Monday. That's today. It's 1 pm and the job is done! PERFECTLY clean, not a pebble out of place. Top shelf service! Pricing was super reasonable so I also had them clean the entire outer shell of the house, all soffits and aluminum, power wash the driveway, clean all the windows and do some ant and spider pest control. 2 men showed up on time and ready to work, Andrew being one of them (all owner operators - no temp kids who know nothing). I can not give a higher recomendation. Nick & Julie Sebastian
