Paul is a very nice gentleman who does what it takes to make sure the customer is satisfied with the results of his service. He replaced the fixed glass side of my sliding glass door. It was a uniquely challenging job, but Paul found a way to make it work and now the door looks and works great!

I recently purchased a condo and had a “vision.” I wanted a mirrored wall similar to a yoga studio, and also a wall in my closet area so I could see myself floor to ceiling. I called Paul & he was awesome. He asked questions, made an appointment to see the space, gave me an estimate and was finished with the job all in about a weeks span. He is communicative and honest. He has been, by far, one of the easiest people to deal with during my condo transformation. I highly highly recommend Costelow glass & door. Five hard stars ⭐️ ⭐️ ⭐️ ⭐️ ⭐️! The work is beautiful. I had three large panels which had to have outlets cut from them, and it all worked out perfectly. Thank you Paul. It was great working with you.

1. High Quality Work 2. Excellent Price 3. Great Communication 4. HONEST Paul installed shower glass panels in two of my bathrooms at my Airbnb rental. He made every effort to accommodate me despite his busy schedule. He actually managed to complete the job before my deadline. The best part is his personality/character is as exceptional as his craftsmanship. I'm giving him rave reviews because it's unique these days to find someone who prioritizes service over profit. Costello Glass is the BEST way to go.

TLDR: Paul here is the right choice. Great customer service, cares for your job, and does excellent work. Reasonably priced, family owned, LE friendly. 10/10.
I called four people shopping for quotes with Paul being the last. Paul didn’t answer so I didn’t bother with a VM since it was the fourth call I made. Paul sent a text within a few minutes saying he would call right back after a job he was on. So Paul started out by prioritizing the work he was on before trying to get a new client. This to me shows that he values your job and won’t half/ass to try and get more clients. This is the quality a small business can provide that big businesses just can’t.
Of the other three calls, two emailed me quotes which were about $150 cheaper than Paul. One tried to put me on hold for a sales representative to speak with me. I decided to go with Paul at the higher price point. It felt like he was the right choice when it came to people that care about your business and he was the small business owner of the bunch. This was the right decision all the way. In passing I mentioned the other two quotes but that I preferred Paul’s business after his candor over the phone. Paul price matched the job for me. I didn’t ask for it nor expected it, but I am grateful for him pushing to meet those prices and ensure I was getting a great deal.
I left Paul hanging for a day or two making the final decision. Paul didn’t try to sales pitch or nag me. He waited for me to reach when I made a final decision. Paul spent a good amount of time on the phone, over text, and in person discussing the job and what was needed. I had no idea what most of what he was saying looked like, so Paul walked me through it and showed several examples to help me picture it all. The final product was as better than expected and then some.
After the work was done, I was uneasy about the security of one side. My job was rather unique with varying measurements and a larger than normal pieces of unsupported glass. Paul walked me through the options and a reasonable price. Paul prioritized getting the addition complete. A small pole that matched my shower hardware was attached and now it’s more than secure and still looks amazing!
Paul was prompt, understanding, detailed, does amazing work, is a small business owner, and cares to give a great service to you both in his product and his communication. If you are shopping for quotes and unsure what you need/want or who is safe to go to, Paul is the one. He is at market price and will provide a great product better than any big businesses trying to send you to a sales representative. Thanks for what you do Paul! Wish I knew how to post the before/after, but if I figure it out I’ll attach for all to see.

I cannot say enough good things about Costelow Glass & Door. From our first call, Paul was clear, friendly, and genuinely focused on solving our problem. He went above and beyond to help with our needs, explained our options without any pressure, and delivered quality work at a fair price. Communication was excellent and everything was handled with care and professionalism. If we ever need glass or door work again, they are our first call, and we recommend them to family, friends, and neighbors without hesitation.

Paul is great! I have hired him on 3 separate occasions and have found him to be:
1 punctual
2 efficient
3 respectful
4 honest
I am a small landlord with just a few properties and I operate on a tight budget. He has replaced windows, sliding patio doors and sliding glass closet doors for me. Paul shows up on time, takes care of business, and offers above average service at a good price. He is THE best option for glass repair in the Mira Mesa/ Rancho Penasquitos / Scripps area. I recommend him with zero hesitation.
Paul was so incredibly easy to work with and did a fabulous job on install. The entire process was quick and efficient. Great family run business. We would absolutely use them again!

Paul Costelow and his team at Costelow Glass & Door did an incredible job installing our new swinging shower door with a top transom, and it turned out beautifully! Paul was an absolute pleasure to work with throughout the process—polite, accountable, and a genuinely nice guy who stands by his work. Custom glass installations can have unexpected visual quirks once the hardware is up, so my best tip is to collaborate closely and talk through every design detail and component upfront. Paul is wonderful at listening and will do whatever it takes to make sure you get exactly what you're picturing. Highly recommend him and Costelow Glass & Door for their fantastic customer service and the gorgeous work on our shower door!
