"Starting a remodel is honestly overwhelming. There are so many companies vying for attention, it gets a bit tiresome. We were introduced to Sean via a neighbor after we saw them having work done on their home. This was an amazing recomendation! I would definitely recommend Gallagher Construction. I look forward to doing additional projects with them in the future. Sean's selection of subcontractors was top notch, I would use any of them for another project. They were all very professional and shared his eye for quality and detail."

“Our experience with Gallagher Construction was fantastic! They really listened to our ideas and made our dream home a reality.”"The project was great. Sean has excellent design sensibilities, solid project management skills and a fantastic crew of hard working, diligent and talented contractors. He did a beautiful job and handled every bump, question, change and request with grace and care. I especially appreciate that he talked us out of silly ideas that would have looked bad and cost more. They are extremely customer-service focused and really care about making sure you love the job 100%. Other perks were having the best dust control/floor protection system I've ever seen and daily site clean up. I did not find a single stray nail or staple!"

"Our project went very well once again.  On-time and on-budget. Our PM, was excellent (once again). They are easy to work with and their construction knowledge & organization is the best I have seen."

"I am positively ecstatic about the quality of installation. They did a terrific job, and have been a pleasure to work with. They listen, have good ideas, pay attention, and are safety-minded, don't leave a mess, or miss any details when passing along my requests. I'm very pleased to have this installation finished well before my deadline."​

We are very happy with the quality of work from Gallagher Construction, our Architecture firm, and all the subcontractors employed to help with our addition project! Sean, and their team did a great job making us feel like we and our needs were always top priority. Our home has been completely transformed and our entry is no longer a source of frustration for us. They are some of the nicest, most honest, and most hardworking guys we've ever had the pleasure of employing! Thank you to the crew at Gallagher!

These guys are great! They are very professional and actually show up when they are scheduled. They follow up with phone calls from their lead person, and let me know the status of the job during each phase. They also cleaned up the work area after finishing they job.Their staff is friendly and courteous, and willing to work around my schedule. I would definitely use this company again for any construction/remodel job I need. I would recommend them to friends and neighbors without any hesitation. A very trustworthy and reliable company!

This was the third full renovation/remodel completed by Gallagher Construction for myself and my family. With all projects they were great about responding to my questions/concerns, accommodated my decision to make changes after the project was started and respected what I needed to accomplish and the time frame I requested. They are hands down the only provider I would use or recommend (and my family has used the services of two other contractors in the past 20 years). I was especially impressed that they were able to complete the bulk of the project (minus my added changes) in the time period I needed so that I would not have to be out of my home or board my dogs and cats longer than initially anticipated. I know it's a minor detail to most people but my pets are a huge part of my life and the fact that they understood and worked with me to accommodate their needs was appreciated. If they are willing to work with my quirks as a client and do a great job, I know they will handle any requests professionally, promptly and with understanding. They are a great company who do quality work!

Overall, we had a great experience with Gallagher Construction! The work that we needed done didn't fall into the category of "fun home improvement projects" that most homeowners look forward to- in fact we were pretty frustrated to learn that the previous owners had allowed the structural condition to get so bad- but Gallagher gave us a tremendous amount of confidence that the work would be done and done right. We requested bids from 4 other providers and although Gallagher fell on the more expensive side of the spectrum, they had a good idea of where the previous owners went wrong and the clearest vision of how to move forward to fix current issues and prevent recurring ones. The entire Gallagher crew was incredibly professional, insightful, and upbeat; Spencer, in particular, was always working very diligently and happy to answer the several dozen questions we had each morning. Once the work was completed, Sean took the time to walk through everything, answer all of our questions, and make sure that everything was done to our satisfaction. We're really looking forward to working with Gallagher again now that we can start planning out the "fun" projects on our home!

Extremely knowledgeable and reliable, true professionals. Timing was key on all of my projects (remodeling a home with 3 little kids around is not ideal) and was impressed by the quality of work they were able to provide in the timeframe given. Give them a call and make your dream a reality!
AL Kent
The project started quickly and progressed well. Sean and his team were very accommodating as we lived in the house while the remodel was going on. The crew were a pleasure to have around. I didn't realize how many subcontractors would be used electrical/roof/gutters and drywall, and I think this bumped the cost, but all the work proceeded quickly and expertly because of this. They did a lovely job matching the existing structure and even making improvements after consulting with me. I'm very happy with the outcome!

The project was great. Both Sean and his crew have excellent design sensibilities, solid project management skills and a fantastic crew of hard working, diligent and talented contractors. They did a beautiful job and handled every bump, question, change and request with grace and care. I especially appreciate that they talked us out of silly ideas that would have looked bad and cost more. They are extremely customer-service focused and really care about making sure you love the job 100%.
