Dmitry is responsive and professional. He helped repair a leaky window by sealing and insulating it. He also explained exactly what he was going to do. The true test of his workmanship is when a storm / rain comes (which has not happened yet). I trust he did a thorough job.

Details: 2 - 4 windows • Window sealing • Water is leaking in • Sliding (slides sideways) • Residential

Dmitri was great to work with. He came out to give me a free estimate to fix a broken window hinge and once he ordered the part and it came in, he contacted me with a date to set up the repair. I’ll be using him for additional window repairs.

Details: 1 window • Windowsill or casing needs repair • Casement (pushes open on a hinge) • Residential

Definitely need to raise Dmitry up for his professional. All of the estimators asked me to replace the whole window or refused to repair. Dmitry can take the job and finished it perfectly! Good job, Dmitry

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

Dmitry responded instantly to my request and was accommodating to my time. He was very careful with the belongings while checking the leak. He repaired and sealed the leak around the window. He took before and after pictures to show his work. Would call him again for any future window issues.

Details: 1 window • Water is leaking in • Sliding (slides sideways) • Residential
