The CKI Experience


Nothing but high accolades for Cathy Kert Interiors...She has a keen, sharp eye for what a house needs, and the ability to get it done on time...Cathy staged my home that was for sale, it SOLD in two days. She is now working to decorate my new home. Thanks Cathy.

Cathy Interiors provided me and my family high quality service at an affordable price. They are flexible, responsive and get the job done. They are wonderful



Cathy is a pleasure to work with. She has a keen sense of design and was a pleasure to collaborate with. She has made our new home on the Cape an oasis. She has a quality team of contractors, painters, plumbers and electricians. The majority of the work was completed while we were not there which speaks volumes how much I trust her and her team. Last but not least, she listens to you and treats both your home and cost as if it were her own. I highly recommend her and in fact we are getting ready to start another project together!

Cathy provided great balance in my wife’s desires and tastes and my concern with staying on budget. I love how our cape house came out.



I recently had the pleasure to work with Cathy Kert on a high end commercial re-fit of a large Dental Office in Hudson NH. The project included a complete demo and redesign of a 1300sq foot reception area.

The client was very detailed and the window to complete the project was very tight as the dental practice would only be closed for the one week of April school vacation.

At our first design meeting I was instantly put at east by Cathy’s familiarity with the design, scope of work as well as the sense of urgency she imparted on the production team. Throughout the process, Cathy was always available to problem solve and smoothly worked with out team to remedy any issue. Cathy also brought in many of her own subcontractors who delivered on our schedule and expectations.

Cathy has a hands on approach which was extremely helpful, especially on the day of delivery when some unforeseen electrical inspection issues arose. She was often on site and was an extremely helpful and calming influence with clients.

5 – star! Cathy is very creative, imaginative, talented, and can visualize the final product from “nothing”. She did the design for the renovation/addition of my kitchen, family room, porch and mudroom. After, she decorated my entire home with an eye for function, fun, value, taste and my needs and wants. She would present options and didn’t have a personal interest if her client rejected some of her ideas and choices. It has been almost 14 years from the start of my project with her and now I want her to return and do it over again!

When we decided to have our kitchen re-modeled, we called Cathy to help us figure out what paint colors and window/table accessories would really make our new granite and flooring “pop.” Cathy has an amazing eye for color and worked with us by providing a variety of options that exceeded our expectations in terms of pulling the entire room together for an elegant, yet contemporary look. She also worked with us to choose material that was durable and easy to clean as this was one of our requirements.

A few months later we decided to remodel our Dining Room.  We called in Cathy, and she worked with us to establish a lighting plan and color pallet that transformed the room from ordinary to extraordinary. She also lined us up with highly professional contractors who did magic with Cathy’s plans.

I really appreciate the way Cathy listens to our ideas and thoughts, then presents us with a few ideas for consideration as we work on narrowing down our selections.  I am honestly amazed at her ability to mix and match colors and patterns to bring the most out of a room.  She is highly talented, and such a wonderful person to work with!!

I am the project manager for the Valle Group who constructed Cathy’s studio space on Cape Cod. She was very thorough and detailed in helping us complete the project just how she wanted it. The studio came out great! We look forward to working with Cathy again.

Cathy transformed our lake house from a frumpy mismatch of furniture to a warm inviting soothing retreat. She is a good listener and her knowledge of the industry and products is incredible.

Everyone who visits comments on the beautiful decor. She stayed on budget and timeline what more can a homeowner ask for?

I am eager to see what ideas she will have for future projects. Her thoughtfulness and encouragement make it a pleasure to work with her.ts on the beautiful decor. She stayed on budget and timeline what more can a homeowner ask for?
