Where the Two Companies Are Similar
Both companies clean exterior glass with water-fed poles and purified water, and both offer window cleaning, gutter cleaning and pressure washing. That similarity matters because the method is a proven one for spot-free glass.
The Glass Association of North America recommends pure water with total dissolved solids of 20 parts per million or less to prevent spotting, which is why professionals use purification systems.
The U.S. Geological Survey notes that hardness comes from dissolved calcium and magnesium, and those minerals are what leave spots behind when tap water dries on glass.
Where They Differ
The clearest differences are size, history and structure. Sunshine has operated since 1978 from Marietta and covers metro Atlanta across five counties. SummitPro is smaller and based in Canton, with 16+ years in business and a focus on Canton and nearby North Georgia towns.
If you want the longest operating history or a guarantee that specifically names a 48-hour streak-free window, Sunshine states that on its site. If you want a Canton-based, family-owned company with the same crew on every visit, that is how we work.
How to Choose Between Two Good Options
When two companies both use water-fed poles and both offer a guarantee, the details decide. Use this checklist:
Ask for the guarantee terms in writing, including the time limit
Confirm which crew will visit and whether it is the same one each time
Ask about proof of insurance
Confirm that screens, tracks and sills are in the quote
Ask how each company handles upper-story windows
The answers show you who has a clear process. Our guide on cleaning windows without streaks shows what a careful finish looks like, so you can judge either company's work by the same standard.
Gutters, Roofs and Height
Both companies clean gutters, and gutters are worth a schedule. The Asphalt Roofing Manufacturers Association recommends that property owners inspect their roof in spring and fall and keep gutters and the roof clear of leaves and pine needles. Height matters for safety as well.
The National Institute for Occupational Safety and Health reports that about 40% of ladder injuries come from an incorrect setup angle, and OSHA's guidance says to keep three points of contact and to extend the ladder three feet above the landing.
Glass and gutters both involve ladder work unless the crew has poles and stabilizing equipment. Ask each company how it handles height.
Why Choose SummitPro for Window and Gutter Cleaning in Canton, GA
Our method for gutters is a three-part visit: hand debris removal, flushing of gutters and downspouts, and an inspection for damage, done with ladder stabilizers and padded equipment that protect your gutters and siding.
North Georgia homes with trees need gutters cleaned three to four times a year, so we plan around the seasons that matter in Cherokee County instead of a generic schedule.

Conclusion
The rule of thumb is to compare companies on method, guarantee terms and insurance, not on age or size alone. Get written estimates on the same scope from each company you are considering, and choose the one that explains its process most clearly.
Frequently Asked Questions
Is a longer time in business better for a window cleaner?
A long history shows staying power, but it does not guarantee a better result on your home. Compare the method, the guarantee and the written estimate along with the years in business.
What is a streak-free guarantee on window cleaning?
It is a promise that the company will return and fix streaks reported within a stated time after the cleaning. The time limit and the process for reporting streaks vary, so ask for the terms in writing.
Do window cleaners need insurance?
Insurance protects you if damage or an injury occurs on your property during the job. Ask any company for proof of coverage before work begins.
How does a water-fed pole clean windows without streaks?
The pole rinses glass with purified water that has had minerals removed, so the glass dries without spots. Glass cleaned this way needs no cleaning solution on the outside.
How do I compare window cleaning quotes?
Make sure each quote covers the same scope, including interior and exterior glass, screens, tracks and upper-story windows. Then compare the method, the guarantee and the insurance coverage.
