Such a wonderful & professional company! They were quick & responsive on EVERYTHING. They safely wore masks, covered up my furniture & prepared everything they needed in their own company truck. I struggled for months with my HOA about this window because not a lot of people were willing to work on my window because it couldn't be retrofitted. Alexander Company were not only willing but they also provided me a fair estmate as well. Definitely recommend & will go to again if I ever decide to replace my doors!

I replaced three slider windows and one large sliding glass door (old aluminum vrs) with Simonton Daylight Max (door was Madeira). These allowed a greater amount of light to enter my dark unit than did other brands. I ask lots of questions, and Rich (salesman) was ever patient in answering them, sometimes more than once. Also, the Alexander Co show room is more accessible (hours, flexibility) than many, a big plus.
The installation team (Gerry et al) was careful of my interior space and did high quality work, inside and out. They were efficient, but not rushed -- they arrived on time. A bonus

Our experience with Alexander Company was fantastic. We first met with Walter a couple of times at their showroom in Burlingame. He patiently answered our questions and guided us to the best window for our needs without overselling a more expensive brand. He came to our house a couple of times to look and measure the windows and make further suggestions based on our house.
The crew that came out to do the work (Jose, Reynaldo, Jerry and Roberto) were prompt, courteous, neat and cleaned up very well after themselves. Their work was meticulous and we are really happy with the windows we chose

We recently had 5 windows replaced in our home and the process was completely painless. Walter came out and took the measurements and discussed our options, and his team came out to do the installation. The guys that did the installation were very polite, cleaned up after themselves so that you wouldn't even have known they were there, and got the job done quickly. There is definitely something to be said about having real pros in your home doing their work; they know what they are doing. The price was right in the range we were expecting to pay, too. We will definitely use them again

From start to finish, the process for our new door was easy, efficient, and well-done.
We got a quick response when we asked for an estimate, and although we had to tweak the estimate a bit, we were quickly able get what we needed.
There was a delay in getting the door manufactured due to COVID (not the fault of Alexander Company), but when the door was available, it was installed within a couple days of delivery. The installation process was fast and professional, and the final result was excellent.
This is the company we will be using again for door replacements.

Needing some replacement windows, I was referred to Alexander Co by my General Contractor and longtime friend. I called for a appointment to get recommendations and can't say enough about the estimator and project manager, Walter.
If you have a difficult or challenging project, make sure that you asked for him. His recommendations were spot-on and I should have an estimate back within a day. The best part about this company is that they not only sell the windows but they have an in-house installation crew and stand behind their work.

We ordered a complete replacement of our windows as they were more than 35 yrs old and were in bad shape. We got in touch with Jeff, the owner of Alexander company and it was a great experience with him. From taking the time to come by and do initial estimations and measurements to explaning the step by step process, to keeping us updated, to contract signing, getting permits and generally being proactive.... it was all done so professionally that we would highly recommend Alexander company for all your installations. Thank you Jeff !

I have used Alexander Glass previously to install 9 Anderson windows in my home. They did a great job!
Recently due to covid I ordered 3 of the same Anderson Windows directly from Home Depot to take advantage of their sale. Savings at HD was great and the windows were delivered directly to my house from Anderson! I waited 12 weeks!
I then called Alexander Glass and left a message for John to call me. I waited a week, no response. I then called again.
The person answering the phone was all set to do an appt until I said I already had the windows. Lots and lots of stupid excuses why they now could

This is the second time I’ve used them for windows. They did an amazing job the first time and it was no different the second. Their consultant was very helpful, flexible and transparent. Worked with us to come up with various configurations and helped us think through various scenarios. The workers are fast and kept the job site clean and did quality work. We love our windows and sliding doors and would highly recommend them to anyone!

Jeff is extremely easy to work with and very professional. The crew of installers were equally as professional, courteous and tidy. They ensured a meticulous install of the windows in our 110 year old house (not everything is exactly plumb in our home!). The Marvin windows and door are exactly what we expected. Highly recommend!

We have used Alexander several times over the past 15+ years, most recently for our front door replacement. Once again, we were completely satisfied. Jeff makes it easy and keeps his schedule commitments. His installers are courteous and professional with superior attention to detail and cleanup.

Alexander Company came out and replaced two French doors with sliding glass doors and did a terrific, and easy for me, job. The estimator was responsive and got me back several iterations of a quote until we had what we wanted, the installers were polite, covid responsible, and did an impeccable job. They handled everything related to permitting, including having the approval emailed to them which allowed them to schedule the plaster replacement as soon as the work was approved. Easy for me and great doors for my house, we couldn't be happier!
