"Santos repaired brickwork on steps and porch foundation; also repaired and painted attic windows and a decorative window on an upper floor. He had to come back to complete the work (because of weather) and he did that promptly. His fee was very reasonable."

"Kareem did an excellent job replacing 4 interior doors in my condo. This building is 60 years old and the door frames are out of alignment. Skillful craftsmanship was needed to plane the doors so they would fit properly. Exceptionally done and the doors open and close securely. Kareem’s very positive, cheerful, and trustworthy; a pleasure to work with. Would certainly hire again should future home repairs be needed."

"Martin came out immediately and installed a 20 ft flag pole in my front yard. He ran into some tree roots and removed them. No problem for him, he was great and did a beautiful job. I hope to hire him soon to build a screened porch"
