Isaac responded immediately to request for work and came late Saturday evening to fix a broken lock which locked me out of the home. Stayed late to replace the lock and fix alignment issues till everything worked well.

Isaac at Nan Construction did a wonderful job for us on a challenging locksmith job, and he did it on a same-day short-notice basis. He went out of his way to make everything perfectly safe for us. He's really professional, this is the best locksmith in the Bay Area.

Issac responded right away and made a same day appointment to replace our door knob. He was very professional and made sure the bolt was a higher quality than the old one. We will be getting all of our locks upgraded with Nan Construction soon!

Isaac truly saved the day for our family! We were locked out and feeling stressed, and he responded quickly, showed up with a calm and understanding attitude, and had us back inside in no time.
But he didn’t stop there — he took the time to install smart locks on both our main and garage doors, and walked us through practical tips to keep our home more secure. You can tell he genuinely cares about doing the job right and looking out for his customers.
His integrity, kindness, and expertise made what could have been a terrible experience actually a really positive one. I wouldn’t hesitate to call Isaac again and will absolutely be recommending him to friends and family!
