He helped me fix 3 doors that weren’t latching. Brought great expert advice. Efficient execution and responsible. I’d definitely hire him again!

Konstantin and Sergii worked to check off a list of repairs in our house ranging from fixing our 67-year-old self-closing door that didn’t self-close, fixing our under-the-cabinet lighting, fixing a bathroom light/fan, and installing our hot water dispenser and water filter. They ran into “snags” along the way (missing parts for the water dispenser) but they worked diligently and efficiently to solve any and all problems. Both are really pleasant and easy to work with and reasonably priced. We will call them again when we have additional work to be done.

Details: Less than 2 hours (Simple tasks) • Kitchen • Plumbing • Doors • Lighting • Home

Konstantin came to my home to asses the situation I had with my metal gate door. He quickly offered me a solution to fix the issue and got it done for me right on the spot. His work is very clean and professional. I absolutely recommend him for any work you may need! Thank you Konstantin!👍🏽

I was so happy to learn that Konstantin and Sergio could come so quickly to repair an emergency that I was having with my patio
sliding door. They were knowledgeable about the necessary
repair and assisted with other problems needing attention. I have already asked them to return and help with other projects. Their price was reasonable and they cleaned up after themselves. I highly recommend them for any household repairs.

Details: Exterior door (e.g. front door, patio door) • Interior door (e.g. bedroom door, closet door) • Sliding door (like an exterior patio door) • Glass • Problems with door swinging or sliding • Problems shutting the door • Problems opening the door • Home
