Martha Spinler
Window Cleaning In El Cajon
All the people involved in the work at my place were very easy to work with and the work was done very quickly. The results were the best I have ever had from a window cleaning service! I like that they guarantee their work and would have come back if I had found something I didn’t like. The gutter guy was very thoughtful and moved his ladder when I had to exit the garage in my car. I will use McCormick’s Window Cleaning from now on. I have been looking for this quality of service for a long time!!!

How do I find the best window cleaners near me?
Finding the best window cleaners near me is a process that requires careful consideration and research. You want to make sure that you hire someone who is experienced and reliable, so it pays off to take your time in selecting the right person.
When evaluating potential window cleaners, here are five key things to consider:
1) Professionalism: Make sure the cleaner you are considering has a professional attitude and always shows up on time. Ask them beforehand what equipment they use and how long they have been in business—this can give you an indication of their experience level.
2) Quality Equipment: Look up reviews of professional window cleaning products online so you can be sure that your provider uses quality tools for their job. Good ladder systems, squeegees, scrapers, towels, ladders, or other extension poles should all be included in their arsenal of products.
3) Reviews: Check out any customer reviews for the cleaner’s services on respected websites like Yelp or Google Business listings before making your decision—this will give you an accurate read on their performance based on the experiences of past consumers who have hired them before.
4) Price Options: Determine if there are any special packages with discounts offered by the company when hiring them for multiple visits throughout the year instead of opting for individual service calls every now and then.
5) Guarantees: Lastly inquire if they provide any type of guarantee along with their services whether it’s free re-cleanings within certain timeline frames if something goes wrong after an initial visit or even refunds/money-back guarantees if not satisfied with results at all — this could help protect against feeling unhappy afterward no matter how skilled/experienced/ready-to-go this contractor may appear at first glance!
How often should windows be professionally cleaned?
Most professional window cleaning companies recommend that you get your windows professionally cleaned at least once every 12 months. If you live in a high-traffic area with a lot of dust, dirt, and grime, then it may be necessary to have them cleaned more frequently – perhaps every 6 months. Professional window cleaners use specialized solutions and equipment to clean the glass thoroughly without damaging the windows. This removes any stuck-on debris or streaks that can accumulate over time, restoring optimal clarity for beautiful views and plenty of natural light indoors.
What happens if solar panels aren't cleaned?
If your solar panel system isn’t cleaned on a regular basis, you may see decreased efficiency over time. This decrease in efficiency is caused by a variety of different factors: dust, dirt, pollen, and leaves can all accumulate on the surface of the panels and block sunlight from reaching them. Additionally, if there’s any moisture present due to rain or snowfall, it can form droplets that also impede normal light absorption.
In addition to reduced energy production from not cleaning your panels regularly, other potential issues arise as well. For example, birds could mistake your panels for nesting material or try to roost on them – resulting in costly repairs or damage to the system. Furthermore, if moisture finds its way under the panels it might cause corrosion or even mold growth which would require additional maintenance costs in order to repair/replace affected parts.
Ultimately solar panel cleaning is essential for maintaining optimal performance levels as well as protecting against preventable damage caused by environmental factors like dirt buildup and rainwater penetration – so make sure to keep up with regular cleaning tasks!

What are the benefits of getting my gutters cleaned by professionals?
Getting your gutters cleaned by professionals is a great way to protect your home from potential water damage. Professional gutter cleaners can provide a thorough, reliable, and safe method for cleaning out debris without any of the risks a homeowner may face when attempting their own maintenance.
The benefits of professional gutter cleaning are numerous – here are just a few:
1. Prevention of Damage – Gutters that aren’t regularly maintained can collect debris, leaves, and other materials which will cause blockages over time. This prevents rainwater from flowing properly away from the house, leading to water-related issues such as basement flooding, foundation erosion, and roof deterioration. Professional gutter cleaners remove all debris leaving you with clean gutters that won’t cause these kinds of problems in the future!
2. Preventive Maintenance – Regularly scheduled professional gutter cleans can save you money in the long run. Especially if they include an evaluation of how old/worn out your existing gutters are as well as pointing out any additional repairs or precautions needed for maximum protection against future household disasters caused by water-related issues!
3. Safety First – Cleaning high-reaching eaves and drains can be dangerous when done yourself due to ladders or scaffolding requirements. So hiring experts who have experience in working at height safely is important for not only preventing accidental slips/falls but also ensuring proper protection against liability claims should an injury occur onsite during cleanings!
