"We needed to change all (18-20) window screens of our 4-bed room SF home. Rolando did a fine job with these replacements. One of the glass windows accidentally got cracked during manipulation (stuff happens!) but, more importantly, he ensured that the new glass window was the same design and was reasonably priced (we split the cost). The 1st window maker he contracted this work out to delivered a window with the wrong design, so Rolando on his own accord identified another maker and got the correct design made. We appreciate that Rolando persevered until he had the original design in hand. We have no reservations in recommending him for any window/screen work."

"Steve and Alex were incredibly great. I was referred by another company when needing a large decorative mirror hung in a dining room. Steve and Alex were extremely professional. Called prior to arrival and were very courteous and did an outstanding installation in record time and with what appeared to be ease and expertise. I would absolutely recommend them and consider the pricing an incredible value for the services provided in my home. Would hire them for this and other glass and mirror installations in the future in a second!"

Window Cleaning questions, answered by experts

Clean regularly and inspect seals for wear. Replace damaged parts promptly to maintain effectiveness.

Distilled white vinegar removes stickers from glass by breaking down the adhesive with its acidic qualities. You can apply the vinegar to the area with a sponge or cleaning cloth. Let it sit for 10 to 20 minutes, and then scrape the area with a plastic scraper or the edge of a credit card.

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.

Most jobs take 2-8 hours, depending on the number of windows, height, and difficulty of access.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.
