Some words from

Our Happy Customers

"The project was doubling the size of a unique log cabin beach house while at the same time protecting its integrity, and not losing seasonal usage and being an absentee owner. From the beginning of the project they handled all permit issues, they managed the project so there were no delays, and they recommended a number of changes to the architect's plans that reduced costs and enchanted appearance. The site was kept immaculate according to neighbors and the workmanship achieved all of our expectations." Bob Nadler - Clinton, CT

"Having worked with so many home remodeling professionals and contractors over the years, we can honestly say that Geoff and Gerard are top of the line in terms of quality, design and communication. They have helped us with projects of all sizes and scopes throughout the past fifteen years, and we trust them above all others with our home and working in and around our family. Their attention to detail - whether it's with craftsmanship, scheduling or otherwise - is second to none. We'd never use anyone else and always look forward to having them in the house." John and Robin Rathjens - Orange, CT

"Keltic Construction had done some renovation work for the prior owners of our home. The work was well done, and of very good quality. We interviewed them and decided to move forward with a $100K renovation project. They were excellent. True professionals, timely, on budget, keep us informed and were very neat, leaving our home spotless upon completion. A pleasure to deal with. We are very satisfied customers of Keltic Construction." Tom Reynolds - Clinton, CT

"Gerard O’Shea (and Keltic Construction) guided us through every step of an indoor and out 3,500 sq ft gut renovation project of our second home. Not only did Gerard supervise the complete rebuild, Keltic aided in design and the budget process. The house had been untouched since 1959. It needed new roof, staircase, interior and exterior walls, complete re-wiring, new plumbing, HVAC installation, new bathrooms, and kitchen. Our NYC architects told us that Keltic is the VERY best builder they have EVER worked with and only wish Keltic would accept work in Brooklyn. Keltic built our outdoor decks, stairs, retaining wall, shower, screened-in porch, garden, and balcony. Gerard’s team showed up early EVERY SINGLE day to work for 9 months and our neighbors finally asked “who ARE those guys? They never miss a day, and work all day long.” Building this home with Keltic has been very rewarding and satisfying. At every step, Gerard provided knowledge and a responsive working relationship. Thank you, G. Anyone looking for a contractor is lucky to be able to hire Keltic. All visitors to our home compliment the great work done" Ken Hochman - Madison, CT

"Keltic has done several large renovations for me and each time I have been impressed by the build quality and attention to detail. Keltic was always on-site when they said they would be and never left for the day without a full clean-up. Estimates were honest and what I ended up paying." John Morgan - Madison, CT

"Keltic Construction rebuilt our house after Hurricane Irene. Gerard and Jeff did much of the work themselves, also utilizing top notch subcontractors for specialized work. Their skill, attention to detail and attention schedule were remarkable. We were very pleased with the final product, which they delivered ahead of schedule. We have used them several other times for smaller projects. They have NEVER disappointed us. We recommend them highly." John and Connie Straub - Clinton, CT
