“GVR not only met, but exceeded our high expectations. We give GVR our highest recommendation. Here's why... * Licensed and bonded, their work meets codes and will pass inspection. * Their price was fair * They finished 2 weeks ahead of the original 7-week estimate * They gave an accurate estimate of the final price up front. Final price was 5% under the original estimate. * Our fabulous assigned designer, Dafne, ensured all fixtures were compatible with existing plumbing connections, made excellent design suggestions and offered a designer discount. (ex: $20/SF tiles for $8/SF). Her 3D renderings showed how all the pieces fit together, and her 2D plans showed where each component would be installed. This was an efficient way to eliminate misunderstandings. * GVR clearly communicated, responded quickly, and welcomed our questions * They were flexible when unforeseen challenges arose, gave several solutions and collaborated to resolve each issue * They worked 24 continuous weekdays on our house sometimes staying until 7.30 PM to do the work to a very high standard, and remain on schedule * They had excellent craftsmen in every trade who gave great advice, yet respected the choices we made * They used only high-quality materials even for items we would never see, but would benefit from for many years * They treated us, our pets and our property with great respect * Every team member was an absolute pleasure to work with * GVR is a company of honorable people who take pride in their work What we did to allow GVR to do their best work * We had a well-defined vision and shared it * We watched YouTube videos to familiarize ourselves with what goes into a renovation * We understood at least one thing would not go according to plan, and stayed flexible and open to solutions * We gathered all fixtures and materials before work started * We were onsite every day to answer questions and make timely decisions * We were engaged in the project, but we didn't get in the craftsmen's way * We trusted GVR's experience and judgment and took most of their suggestions * We stayed focused on the 3 things that were most important to the design and to our comfort and convenience * We tried to keep our pets well clear of the worksite * We showed our genuine appreciation and respect every day to every craftsman * We offered Gatorade, chilled water, and snacks * We paid our invoices as soon as they came in * We invited our neighbors to come see GVR's handiwork * We recommend GVR whenever we can Here's what we learned: * Hire a licensed firm you trust * Clearly communicate what is important to you * Plan well, then let the artisans do their job * Understand the time and expense to fulfill non-standard requests * Learn what goes into each phase of work. * Keep confirming your mutual understanding * Be prepared to compromise when the unexpected arises We had an incredible experience with GVR. Every time we use our bathroom we will feel joy.”

“I recently had my yard redone by Seafield Landscape, and I’m very happy with the results. My property is on a steep hill, and they did a great job making the space functional and accessible. They extended the deck, added stairs down to the bottom of the yard, installed gravel deck areas, and put in new grass. Everything came together really nicely and completely transformed the space. I’d definitely recommend them for anyone looking to improve a challenging yard.”

“The project that EBCON Co. did for me wrapped up about a week ago. I thought they did an excellent job. The project was to design and build an ensuite addition to my house for my disabled sister, who will be moving in with me in a couple of months. I hired EBCON for the project as they had done my home remodel when I moved into my current house 10 years ago. I was very happy with that project and pleased that several of their key personnel and subcontractors were the same as for my previous project. The current project consisted of a bedroom/studio, bath, hallway/study, walk-through clothes closet, lots of storage space, and small outdoor patio with wheelchair ramp. As my sister is an artist and art teacher, we asked for a design that provided high walls for hanging her paintings and extra space in the bedroom/studio for her to paint and potentially teach a few students. The design process went very well. The designer worked constructively with us and made numerous trips to tile, stone, and carpet stores with us to select materials. We greatly appreciated the detailed plan skeches she generated, some of which showed my sister’s paintings up on the walls in her bedroom/studio! Challenges, including access to the addition through existing bedrooms and integrating the design with the existing house, were solved well. ADA guidelines for accessibility were strictly followed for the design and materials. We – and all our family and friends - love the design and how it has turned out. The construction work was very high quality – EBCON has very high standards for the work done on their projects, including for the smallest details. The EBCON team and the sub-contractors they brought in were great to work with through all the stages, including design, construction, and completion. In addition to weekly on-site progress meetings (which included the project manager, superintendent, designer, and often the head of the company), I was kept informed on a daily basis about what was happening and the timing for next steps. EBCON staff were always on site while work was being done, and they were always reachable for conversations. Overall we are very happy with the project. I would definitely use EBCON again were I to have another project, and I recommend them without reservation to anyone planning a large or small home construction or renovation project.”
