The Simonsen window which was ordered and installed is much too hard to raise. It is either a problem with the measurement or the window sliders (is this the correct word) themselves. Either way, it is really difficult, and I felt as if my concern wasn’t addressed as I should have been more insistent and expressed how the window needed to be easier for me to raise.

Details: 1 window • Won't open or close properly • Double hung (slides up and down) • Skylight • Residential

Albee and his colleague Ryan were both very responsive. Despite rescheduling due to weather concerns or scheduling conflicts, Albee and Ryan were very responsive and professional. The service they provided had great value. I was replacing a double-hung (double-glass) window that was broken from putting a floating desk on my window (pro tip: don't do it!). They just replaced the glass on the window; I received many other quotes where I was told I would need to replace the entire bottom pane and encasing just to fix the window. I appreciate them for their service and the quality of the work for just what I needed.

Details: 1 window • Broken glass • Residential

FAQs

What should the customer know about your pricing (e.g., discounts, fees)?
We provide free onsite estimates in San Francisco. If it's outside of San Francisco, we do require a $145 service fee for onsite estimates. However, the service fee will go toward the job cost if you ended up deciding to work with us.
What is your typical process for working with a new customer?
It would be ideal if you can provide pictures first so we can have an initial discussion if we can help or not before we travel onsite to save both parties time.
What education and/or training do you have that relates to your work?
Ryan is a C17 licensed glazier with 16 years of experience. He gains all the experiences from the real field in both commercial and residential. Windows repair, glass replacements, storefront windows, and shower doors are our specialties.
