We live in a historic district in Washington, D.C. and wanted to raise the roof on our attic. Our architect recommended Blue Sea for the construction, and we could not be happier with the results. Blue Sea removed our existing conventional roof and artfully expanded our usable space without violating the height restrictions through a unique V-shaped roof. Chris and his team were exceptional from inception to completion. An idiosyncratic project like ours, which included a specially-designed drainage system, is inherently stressful. With Blue Sea, however, our concerns were minimized. They educated us from the beginning about what we could expect, were available at all times (day and night) to respond to any questions we had during the process, and were invaluable with, frankly, really cool suggestions for what has become hands-down the favorite part of our home. They custom-built every nook and cranny of the new space to accommodate our vision and existing furniture, and to a person seemed really invested in delivering a high quality product. And they came in under budget.

They really earned our trust, respect, and friendship. They were a pleasure to work with. I cannot recommend them highly enough for work in the District, particularly with unique or challenging projects.


This is a quality organization. Work is done to your satisfaction. Estimates are honored. Workers are very nice people. Subs are monitored and removed if found to be not up to their standards. Head man(Chris) is an extremely likeable guy who cares deeply about the finish work. This is a small business with the outcomes of a major construction group. Even though my work was completed several years back, I remain in touch with them as I have other projects to pursue and I would not choose another unknown group for this work. Probably the most important characteristic one should look for in a construction company, is their ability to be flexible, to be agile, and most importantly to be seriously concerned about your happiness with the final work. Blue Sea does this and more.

Blue Sea Construction was fabulous starting with their proposal and through ’til project completion. They were on budget and on time,and set our expectations properly every step of the way. The same workers were here throughout the project and we were on a first name basis with the carpenters, electricians and painters. Chris was onsite every day to make sure things were going according to plan. The workers arrived by 7:15 every morning even in horrible weather, they took a quick lunch and worked a long full day. Everyone was so nice and good at their jobs. We miss them and our front porch is the envy of the neighborhood. I HIGHLY recommend working with this group.

We searched out Blue Sea because many of the projects that we liked in our Rosemont/Del Ray neighborhood were completed by Blue Sea. We have a 1927, Craftsman-style home and it was important to us to build an addition that fit with the rest of the home. Chris Gayhardt has an eye for detail, particularly with older homes – doors, trim, windows, pitch of roof – all of the details that pull a home together. We also appreciated Chris’ energy and ability to listen to what we wanted. While he was able to lay out the impact of certain decisions, he never said something was impossible. Blue Sea stuck to its projected budget that was clearly outlined in the contract and divided up into tranches that were paid as Blue Sea completed those portions of the building project. We definitely were able to live in our home while Blue Sea was working on it. Chris and his team meticulously cleaned up at the end of every day and kept their work contained. The neighbors did not mind their presence and Blue Sea was respectful of the neighborhood. We found Blue Sea’s employees to be trustworthy, friendly, and courteous. We trusted Chris with our home and our dog, and are very pleased with the end result.

I was very pleased with my experience working with Chris and the whole Blue Sea team. The project turned out great and really increased the value of our home. The Blue Sea team has great attention to detail and worked closely with our architect, to ensure that the work was completed as designed. The project came in on time and budget, and Chris was very helpful at talking through issues that were encountered, and recommending solutions to keep the project on track. Even my neighbors commented on how nice the guys were! We are looking forward to discussing future renovation projects with Blue Sea.
