"Jeff and his team did a great job with my bathroom renovation. Jeff was informative and patient when giving explanations and options, and also had great communication throughout the process. They arrived on time and were very professional. I would hire again for any other projects."

"Jon did an excellent job of transforming our outdated, broken bathroom into one that is in showroom condition. The bathroom required more work and time than anticipated and he was at our house everyday putting it all back together. We will have Jon return to our house for future jobs and we highly recommend him for any project that you are considering. Most importantly, Jon listens to and respects women. If there is a problem he will offer solutions/alternatives."

"My wife and I have owned several historic homes. Our favorite is the one we live in now, a former carriage house, built in 1865. We believe strongly that one of the primary duties inherent in having such a house is being a good steward--not just taking good care of it, but making sure that the work done to it is of the highest quality. In short, we have very standards; the house deserves nothing less. LOPCO not only lived up to those standards, but exceeded them. Their work ethic, attention to detail, knowledge, experience, and leadership were exceptional. And it was all done on time and on budget. We can honestly say this was the best experience we've ever had with a contractor. We offer LOPCO our strongest possible recommendation, without hesitation."

"We hired Al to replace the stairs in our raised ranch in preparation for finishing the basement. Two other contractors bid on the project, and we're so glad we went with Al. His craftsmanship is outstanding. He came up with creative, practical solutions to the many problems our horrible stairs presented, and we couldn't be more pleased with the results. He accommodated all of my requests, and made sure we were communicating clearly when changes were made to the original plan. When his tile contractor was not available, he did the tile on the landing himself, and I still smile whenever I look at it. Everyone who knows what our stairs looked like before, including the building inspector and our boiler technician, has praised the quality and appearance of Al's work. On top of that, he's a very personable man, easy to work with, very considerate. Now that we are going ahead with the basement finishing, we are confident that Al will do the job to the same superior standard. He is again facing many challenges, and I'm sure that again the results will not only meet code and deliver on all that we ask but will be better than we imagined. I would recommend him without hesitation to anyone who wants the job done right."

Barndominium Builders FAQs, answered by experts

Yes, barndominiums can be two stories. Blueprints for barndominiums can safely support multiple stories or vaulted ceiling heights of 14 feet or more. Barndominiums are prized for their ability to be modified and customized to suit the builder’s preferences, and many barndominium construction companies offer a variety of different floor plans to choose from.

Average barndominiums last between 50 and 150 years depending on the materials they are made from, how well they are maintained, and the environment they are built in. Barndominiums are very durable and have a much longer lifespan than traditional wood homes. With proper care and maintenance, well-built barndominium homes can last generations. 

The lifespan of a barn is typically 40 to 60 years, but with skillful construction and proper maintenance, it can last up to 100 years. The actual lifespan depends on several factors, including the barn type, materials, usage, and climate. For example, the posts of a pole barn should last 50 years or longer, but if the structure is used for livestock in a rainy climate, it may rot within the first decade. Custom designs with high-end materials tend to last the longest. To get the best estimate for your barn's lifespan, you should consider its material type and intended use.

Due to the expansion of the tiny house movement, you can usually find tiny houses to buy in your state. Prices range considerably based on size, style, and type. If you’re looking for a tiny home that’s move-in ready, you may be able to find a good deal to buy or a prefab dealer near you. 

Yes, barn doors can be too heavy, although the limitation is usually imposed by the mounting hardware you buy and not your home’s framing, unless you’re building an unusually wide door. To keep the weight down, you can opt for 1-by material rather than 2-by material, and choose a softwood like pine rather than a hardwood like maple or oak. Check the weight limits on your mounting hardware, and always attach your door track to studs rather than to drywall anchors.
