    Thorough job. Upstairs is much warmer. Hired them to fix ice dam problem. Looking forward to lower heating bills.

    5.0 Whitney C. Albany, NY

    Todd and Greg were awesome to work with on our insulation project. They came in and made great recommendations on what we could do to improve the insulation in our older home, followed through and delivered. They were very easy to work with and came up with solutions to any issues that arose. They are honest, trust worthy and did what they said they would do. The house is warmer and I anticipate cost savings now and into the future. Great communication, I would HIGHLY recommend Stallmer & Sun for any project you have!

    5.0 Neil R. Queensbury, NY

    Reliable and the job was done as quoted

    5.0 Krista H. Mayfield, NY

    Todd & Greg came to reinsulate the attic, fixing any air leaks and gaps with cellulose and foam insulation in the basement around the rim joist. Todd was very responsive to initial phone calls and coming to the house to do an evaluation. They were good in explaining issues and taking pictures to document them. The work they did was complete and thorough and left every night by cleaning the respective areas. As a result of their work we are now experiencing a warmer and more comfortable home to live in.

    5.0 Allison B. Gloversville, NY

    Todd was great - he was direct in assessing our needs and made cost-saving suggestions. He was also patient it took us some time getting back to him during the busy holidays. Definitely recommend Stallmer & Sun!


    Completely re-modeled our kitchen. Removed 2 walls, laid new flooring, new lights and outlets, installed custom cabs, re-positioned sink, and tiled the backsplash. Completely transformed our old drab kitchen into something bright and new. They communicated with us during all phases of the project and never made us feel pressured. Their finished work is immaculate. Not even the smallest detail is overlooked. These guys know what they are doing and they do it well. We would 100% recommend it.

    5.0 Dave C. Waterford, NY

    These guys completely transformed our laundry room. Took out a closet, moved the washer and dryer, installed tile flooring, and built gorgeous custom cabinets. It's the best room in the house. They worked on schedule, consulted us on design ideas, etc. I can't recommend them more.

    5.0 Stephen C. Niskayuna, NY

    Todd and his crew did a fantastic job installing a tile backsplash in our kitchen and other kitchen renovations. The tile job was done very well and my wife and I are very happy with the finished work. Great value for a craftsman.

    5.0 Michael J. Schenectady, NY

    Very professional quality work.
