"We could not be more happy with the job Hire Her Home Improvement did on our project. This is our 2nd time working with Angela and her team, and they did a fabulous job. We had a new floor put in our main kitchen, and a major rebuild in the basement apartment after mold remediation. This included masonry and plumbing, drywall, trim, and studs,cabinet rebuild, painting, and tile floor installation in multiple rooms. All Angela's workers are very skilled, respectful to your home, and punctual. They turned our nightmare into a dream come true after our awful experience finding mold in our house.

Contact the professionals at Tito's Home Improvement today and let us get to work for you!

"Excellent - Tito was extremely responsive and his team did excellent work. I shopped around and got multiple quotes, and his was the lowest. More importantly, he had done work on a number of my neighbors’ homes and came highly recommended. His team was very responsive and got the work done on a short time frame which was great because I needed much of the work done before I moved in to my new home. My floors and skylights look great and I have full confidence in his work. One thing which I really liked is the fact that he is constantly in communication, is always available, and is local. The last part is important because he understands the importance of reputation which gives me full confidence in his work. I will definitely be coming back to him again for any future work on my house and wholeheartedly recommend!"
