Cornerstone did my mother-in-law's windows and made her so happy. She had just gone through chemo and having the windows cleaned and the crew being so considerate of her made things a lot better for her. Recommend Cornerstone to everyone.

This is our second time working with cornerstone. On both occasions they cut corners and left parts of our roof with debris and untreated. No attention to detail and their response was “make sure to pass it on to our project manager and let him know that the crew needs to make sure to be treating the roofs better.” They don’t seem to care about their customers or quality of work. We won’t be back again.

DON'T USE THESE PEOPLE! I have nothing good to say. They used so much bleach to pressure wash my house that the inside of my house wreaked of chlorine. I couldn't go indoors for a couple hours and, after I told them not to go on the deck, they killed nearly every plant on the deck with the over-concentrated bleach spray. They did not respond to my review email and just ran my credit card. ZERO STARS!!!

I have been a repeat customer for several years now and often recommend their services to others. They come to my home three times a year to clean windows, remove debris from the rain gutters, and treat the roof to prevent moss. Ryan and his crew are top notch, always attentive to my needs and always punctual.

There was a lot of debris on the roof. When the crew finished, the roof was clean and treated for moss. The gutters were clean, the downspouts were unclogged, and the clean-up was thorough.

What is gutter cleaning and why is it important?

Gutter cleaning is the process of removing debris, such as leaves, twigs, and dirt, from your home’s rain gutters. It’s an essential part of home maintenance that ensures water can flow freely off your roof and away from your property.

The importance of gutter cleaning cannot be overstated. When gutters are clogged with debris, they can’t effectively direct water away from your home. This can lead to a multitude of problems. Firstly, overflowing water can damage your home’s siding, and paintwork, or even seep into your interior walls causing dampness and mold growth. Secondly, it can lead to water pooling around the base of your home, potentially damaging the foundation over time.

Moreover, stagnant water in clogged gutters can become a breeding ground for pests like mosquitoes. On the other hand, the excess weight of accumulated debris and trapped water can cause gutters to sag or pull away from the house, leading to structural damage. Therefore, regular gutter cleaning is crucial to maintain the integrity of your home and prevent costly repairs in the future. Special thanks to Orange County Wash Pros for answering this question!

Is tile roof cleaning necessary?

Tile roof cleaning is indeed necessary for several reasons, primarily to extend the lifespan of your roofing material. While the buildup of algae might not be harmful to some roofing materials like asphalt shingles, moss can cause significant damage. Regular cleaning prevents the accumulation of these organic materials, helping to maintain the integrity of your roof over time.

Moreover, maintaining a clean tile roof also improves energy efficiency. Free from debris and organic growth, a clean tile roof can significantly reduce heat absorption, thereby lowering cooling costs. However, it’s important to note that improper cleaning methods, such as pressure washing, can cause premature aging of the roof. Therefore, it’s recommended to use gentle cleaning methods or hire professionals to ensure the job is done correctly. Huge thank you to Ducky’s Pro-Wash for this information!

What is a pressure washing service?

A pressure washing service provides specialized cleaning by using high-pressure water spray to effectively remove dirt, algae, mold, loose paint, and other build-up from various outdoor surfaces. This service is commonly applied to buildings, homes, driveways, decks, and patios, offering a deep clean that is often difficult to achieve through traditional cleaning methods. The pressurized water can penetrate and clean textured surfaces like concrete and wood, making it an efficient solution for revitalizing the exterior appearance of properties.

Opting for a professional pressure washing service can not only enhance the aesthetic appeal of a property but also contribute to its maintenance and longevity. By removing harmful substances that can cause wear over time, such as mold and mildew, pressure washing helps preserve the structural integrity of surfaces. It’s a proactive measure that homeowners and business owners can take to avoid costly repairs in the future, ensuring surfaces remain clean, safe, and visually appealing without the use of abrasive chemicals or manual scrubbing.
