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

Dmitry was great to work with, very professional, responsive and communicative. He was able to assess the issue via the photos I sent, explain the cause and propose a solution. Within 24hrs of initial contact, he helped repair the broken latch as well as align the window so it easily slides open/close now.

Details: 1 window • Won't open or close properly • 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
