Your Trusted General Contractor in Nashua, NH 

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value We don't know where to begin. Craig and Greg did an outstanding job with our house. We had a fire back on 9/20/19 which was devastating for us. We had to find a general contractor to renovate our whole house. When we first met Craig for the initial consultation, we knew right then and there he was the one we wanted to go with. His professionalism and knowledge made us very comfortable. Craig and his team went above and beyond our expectations. He gave great advise and had great ideas. He also made sure our house was up to code. We trusted his judgement throughout the whole process. He made the process stress free and worry free. He renovated 2 bedrooms, 2 bathrooms, hallways, living room, kitchen, siding, roof, as well as our stairs indoor and outdoor. He also made our living room and kitchen open concept by taking down the wall that was in between.  The venders that Craig works with were great as well. I can't say enough about Haji who did our shower tiles and back splash, as well as Larry who was the electrician, and the plumber did a great job as well. Craig kept great contact with us at all times. He always made sure everything was perfect. Pictures do it no justice. My kids hear a vehicle pulling up and they think it's Craig and Greg :-) Working with them turned them into family. They will be missed.

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value We were recommended Craig and TSI from a friend of a friend. Having shopped around for companies to replace our roof, we had not had much luck. Craig was quick to come out, provide us a fair quote, and even saved us a considerable amount of money compared to other companies in the nashua area. The crew came out, replaced our roof and even cleaned up the yard in a single day. They even came back a few days later to do a full walk through with us and quality checked. I highly recommend TSI!

Positive: Professionalism, Quality, Responsiveness, Value We want to start off by thanking Craig, Greg and their entire team at TSI for their professionalism and their quality of work on our major renovation/remodel of our home. My wife and I were looking to have a major remodel/redesign of our outdated kitchen and living area and we are glad we found Craig at TSI. Craig was personable and listened to our wants in regards to the work we desired. He walked us through the work he'd perform and offered ideas and with the help from Nancy at Specialty Kitchens came up with the redesign layout of our new and much improved kitchen and living area. We loved what the layout could become and was blown away by what it did become. Craig was also great at communicating with us on what work would be performed and by whom and on what days of the week.  This took out the guessing on when the work may or may not get done.  This was encouraging as you could see the progress being made. Any home renovation/remodel can be stressful time. Add on a pandemic, and talk about stress. Both Craig and Greg however managed to relieve those stresses by staying in contact,  getting the work promised done and done very well but also brought a smile and laughter which put us at ease through a stressful time. Craig, Greg and their team were of the utmost quality and professionalism and we are extremely happy the way the jobs were preformed and executed. We couldn't be happier and if you're thinking about remodel/redesign big or small Craig, Greg and the team at TSI will not disappoint.

Craig and his team recently finished our basement. We cannot say enough how well it turned out!  Their attention to detail is great!  They were very good at listening to our input and also giving their ideas. Craig worked with us to come up with the best layout as we continued finish the basement. The best part is that you can trust them!  Everyone from Craig, Greg, Larry, etc. was extremely friendly and with a wife and 4 children home most of the time it was refreshing knowing we were working with good people too. Our kids loved the team! I would recommend them to others and we are already considering them for another future project too.

Tangent Sphere just finished my basement and I can't say enough about how well everything went. From the first meeting and quote, everything was done so professionally and with care. Craig always kept us informed on what work was going to be done and when each phase would be finished. I felt like Craig and his right hand man Greg went above and beyond the entire way. The finishings look better than what I expected and they even entertained my 3 kids at times! My kids now ask, "where are Craig and Greg." We always felt like we  were in very trust worthy hands.  Communication was always great and the final outcome is even better.

Craig presented us with a clear contract of services and expectations and was very accurate with time estimates and details. He arrived when he said he would, cleaned up every day, handled communication with sub contractors and was respectful of my home and family. So basically, our project, a room over the garage, was completed on time and on budget. We are very happy with our experience and would recommend him to anyone.

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value I can't even express how happy we are with our new space! Craig and Greg did a phenomenal job! They were patient with my (many) demands and even rolled with a bunch of interruptions from our kiddos. They went above and beyond for us and the quality of work they did far exceeded our expectations. They were professional from start to finish and we are thrilled with the overall result! Our basement doesn't feel like a basement and flows seamlessly with the rest of our home. They came highly recommended and did not disappoint!

We used Tangent Sphere to finish off the space above our garage and would highly recommend them to anyone.  They are professional, meticulous, and awesome about taking the time to think about what would work best in the space instead of just throwing up whatever is quickest or easiest.  They were great about asking for our input as well.  They are courteous and respectful in and around our home and honestly the kids and I miss having them around!  Will definitely do business with them in the future.

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value TSI did our roof - and not only did they do an amazing job, but they came back with their crew the next day to fix a few things they didn’t think were perfect. Who does that? Amazing. So happy I chose them for our roof job and will be using them in the future.

Craig and his crew did in amazing job on our basement. He finished early and on budget. Gave great advice and does high quality work. Our basement is now an extension of our home. I will bring him back for future projects and highly recommend him if you are looking for quality results.

Just had these guys remodel our basement! wow! very professional and talented crew!

Craig and team did an amazing job renovating our bathroom.  They were pleasant, professional and very helpful during a tough time.  They helped us make decisions, and gave great recommendations.  Craig went above and beyond to help us finish this project.  Highly recommend.

Craig, owner of tangent sphere inc, was a fantastic contractor to work with. He was patient throughout the process with all our questions. We just finished a major renovation/addition that took about 10 months to complete. He was very particular and had great attention to detail. Craig, Greg and all the sub contractors were a pleasure to work with throughout the whole process. Everything came out the way we envisioned from the beginning. Craig was able to accommodate all our wants, even a little hideaway closet for our daughter under the stairs. Not only did we have the addition, but Craig was able to open up our current space. Craig stuck to the contract and everything went smooth throughout the entire process.

I can't even express how happy we are with our new space. Craig and Greg did a phenomenal job! They were patient with my (many) demands and even rolled with a bunch of interruptions from our kiddos. They were professional from start to finish and we are thrilled with the level of work they did. Our basement doesn't feel like a basement and flows seamlessly with the rest of our home. They came highly recommended and did not disappoint.

Craig and his term finished our basement in Feb 2018. We highly recommend this company. He was thorough, professional and most importantly, we trusted him in our home. We love our finished space and cant wait to use him on future projects.
