Steps In Professional Window Cleaning
Wash With A Strip Applicator
The long cloth head of a strip applicator soaks up a lot of soapy water and knocks dirt loose without scratching the glass.
Wipe Clean With A Squeegee
Starting at the top left, pull the squeegee over the soapy pane in a reverse-S pattern (left-handers would start at the top right). At the end of each stroke, wipe the squeegee blade clean with a lint-free rag.
Dry Off Remaining Drips
Remove any water remaining on the edges of the glass with a damp, wrung-dry chamois, which soaks up wetness without leaving streaks. Dry the windowsill with a rag.
Scrubbing The Panes
A handheld sponge or hog-bristle brush works best on multi-pane windows. Using the same solution of a squirt of liquid soap in water, rub each pane from left to right, top to bottom, working the sponge edges or brush bristles into the corners to loosen dirt.
Questions To Ask Your Local Window Cleaning Company
Are you licensed, and insured?
The professional cleaning companies you interview should be able to provide their licenses and certifications when you meet with them in person, and even have them listed on their website. Professional window cleaning companies should also carry both liability and workman’s compensation insurance.
Do you offer free estimates?
A reputable, honest company should come out to your home and estimate the work for FREE. Be sure to get at least 3 estimates and compare not just the costs but also the services provided. Paying a little more for a job well done the first time is better than paying for cheap service multiple times.
Do you have your own employees, or do you subcontract the work?
If the window cleaning company uses subcontractors, best bet would be to just move on.
What is your window cleaning process?
Ask how the process works and the types of chemicals that are used.
How many people will be needed to clean the windows?
It's good to know how many people will be in your home beforehand.
How long should the process take?
This is so you can make preparations for the whole process.
Ask For The License - Ask for all local and state business licenses.
Proof Of Insurance- For your own protection, check proof of both workman's compensation and liability Insurance.
Business Stability- Find out how long the company has been in business.
Check Online Reviews - You're probably not the first person in town looking for their services. Rely on the internet to get reviews written by people in your community.
References - Expect any top-notch company to be able to provide you with references upon request. Once you have these names, contact the clients to get information about the quality service. When you call, ask questions about the work, timeliness, cost and whether the clients would use the company again for future work.
24-hour Emergency Service - Make sure your local company offers emergency 24 hour service. If something goes wrong, it's good to know that you will not have to wait days for them to come out and fix it.
Over The Phone Pricing - Honest estimates simply cannot be given over the phone - especially if you aren't talking with an actual technician when you call.
Free Estimates - Most companies offer free estimates. This is important because they can provide you with the costs upfront, so that you are not shocked with a bill after the services are completed.
Safety Record - Safety can be a significant factor, so ask the company about their safety records to ensure that any service professional you hire has a satisfactory safety record. You want a company that doesn’t have a high incidence of on-the-job mishaps or injuries.
Satisfaction Guarantee - Choosing a company that offers a satisfaction guarantee will ensure that they will get the job done right the first time and will save you money and frustration in the long run.
Cleanup - The mess left behind after a project can be major. Ask what cleanup work the company includes with it's services.
