The attention to detail was outstanding, and every aspect of the job was completed with precision and care.Posted on Google Liana Gerecht27/06/2026 We couldn’t recommend using Titanium Painting and Renovation enough! They refinished our hardwood floors, put in hardwood stairs, installed a microwave, took down wallpaper and repainted our kitchen and were beyond incredible to work with! I was so impressed with Vinny’s communication with us every step of the way and appreciated their quick turn around times to get everything done before we moved in to our Marlborough home. They were very communicative and honest with us whenever a decision needed to be made, talking us through various options. Every single person was thorough, friendly and easy to work with! We will definitely be using them again for our future home renovation projects.Posted on Google Heb Matthews18/06/2026 Great job with 2 decks-one with stain and one oiled.

This was our first time renovating in our new home, and Vini and his team were incredibly patient and accommodating throughout the process. Vini checked in almost every day to let us know what was going on and you could tell him and his team really cared about the outcome of the work that they were doing. We are really happy with the way our bathroom turned out and plan on working with Vini and his team in the future for other projects!Posted on Google Barbara Menefee09/06/2026 I contacted Titanium about our desired project. Someone came to the house within 48 hours and went over all the projects which included (but limited to) a brand new bathroom and mold remediation downstairs; painting of walls, trim, etc. Painting of all the walls upstairs and trim . Installing a new chandelier; painting a cabinet; grouting in upstairs bath, etc. I give high points for communication, respect, etc. The project leader comes every day to be sure the customer is happy and insure projects are on time. It was refreshing not having to chase them down. I highly recommend them!Posted on Google Mark Elguizaoui06/06/2026 Vinny and his crew were fantastic to work with from start to finish.
