“Alexander Jr. Building Services did a major masonry project for our three-story single-family house...”

Alexander Jr. Building Services did a major masonry project for our three-story single-family house in March 2025: washing, caulking, sealing, waterproofing, and painting. Their price was extremely fair and their workmanship was excellent! Very professional team: easy to communicate with, accommodating, reliable, efficient, and always on time. Would not hesitate to hire them again!

“We had masonry, painting and tuckpointing completed by Alexander and team.”

We had masonry, painting and tuckpointing completed by Alexander and team. They did a fantastic job!!! They were professional, timely, responsive and thorough. I felt like they were doing the work as if it was being done on their own home. I am so impressed. I would give their work 100 stars if that was an option. In Chicago, it can be a challenge to find companies that do a great job. I strongly recommend this company. I will absolutely hire them again when I need a job done. Thank you so very much, bobbi.

“Alejandro and his crew were fantastic.”

Alejandro and his crew were fantastic. They did a tremendous amount of work on the outside of our building (caulking, sealing and painting). The bid was highly competitive. Everyone was very professional and careful. Alejandro provided updates, answered all questions and concerns. I would highly recommend him. I cannot say enough good things about this company.

“We just finished our second experience with Alexander Jr.”

We just finished our second experience with Alexander Jr. Building Services for our four-level condo building requiring sealant maintenance/repair. Their estimate for the work was competitive against other companies we met and the resulting work is high quality. Both in 2024 and back in 2014, our experiences with Alexander Jr. Building Services has been strongly positive. From setting up the estimate appointment to work completion, every step of the process was convenient, timely, and professional. Alexander was easily accessible and quickly responsive to every email message and phone call. Based on both our experiences, I strongly recommend Alexander Jr. Building Services.

“The Alexander Jr.”

The Alexander Jr. crew first worked on our house in Bucktown when we purchased it in 2013. They did a great job waterproofing the exterior of the block at a good price. This past year, we decided to paint the exterior of the house and of the garage. Their quote was again more than fair, and we hired them based on our previous experience. They adressed some tuckpointing issues, painted the block and took special care painting the brick facade of the home. They were able to work around the trees planted along one side of our home, which had been a concern. The guys took good care of the property, cleaned up daily, and finished the work quickly. Any questions we had were answered within a couple hours each time. The new paint looks great. We are very happy with the outcome and the process, and absolutely recommend AJBS Inc.
