"So happy we chose R&D for our exterior wall repairs! they were great to work with throughout the process of what turned out to be a complicated issue. Their communication was really appreciated as they dug into things and problem solved some unique issues with how the previous home owners had cut corners on the house. R&D wasn’t the cheapest initial bid we received but I have no doubt that we would have wound up paying more in the end for a lower quality result with anyone else. Thanks guys!"

"I have an appointment for him to come this year. I only use him once a year. About this time of year I call him. I have a double and some of my windows are giant windows. Some of the windows are screen so he does not do all the window. He is very reasonable that's why I call him. He only lives around the corner from me so I don't know if that's the reason but I am not questioning it. He is very nice. I call him and make an appointment because sometimes he is very busy. When I call him I ask if he can come within a week. But if he is not easy he will come within 2 or 3 days. This time I waited a week which I do not care. Price is reasonable. He knows what he is doing. He has to use a ladder. I leave him a message and some times I have to wait a day for him to call me back but I know he will call me back. He comes very early like 8 in the morning. It is always very early in the morning. He is very nice, very nice. I have been using him for years. He use to be cheaper but I do not complain. I am very happy with him that is why I call him every year."

"I could not recommend Harold's Enterprises more highly. I reached out to Harold based on his listing on Angie's List before I bought my home--free of charge, he took a look at the roof on a property I was considering buying--giving me an estimate and advice. His help led me to find that the sellers were dishonest about the condition of and work done on their roof, and I purchased a different property in Hudson, NY. My home is a 1927 Craftsman that needed quite a bit of work. I hired Harold based on his honesty and responsiveness in helping me evaluate the first property. True to form, his estimate and ultimate cost to repaint the entire interior, repair and sheetrock floors and ceilings, refinish and replace hardwood floors, completely remodel a bathroom, rewire and install light fixtures, match original woodworking, install cabinetry, windows, and appliances, and even assist with installing new furniture, were more than reasonable. Better yet, the quality of his work was of the highest caliber. He has restored and improved a lovely home, and I am so thankful! I have to say that most of all, I am so happy with Harold's professionalism and diligence. Not every contractor is known for staying on the job and completing it on time. Especially in my situation, where I am a single woman trying to restore a second home when I live out of state--I assumed I would have difficulty in getting any contractor to be present and complete the job on time. However, this was never a problem. Harold was always there, was immediately responsive, and never slacked off when I wasn't there. I plan to work with Harold as much as possible in the future as I continue to improve my Hudson home. I recommend him very highly."

"Alan and the employees of Crowe Town Construction are a part measure to work with. They treated us and our house with respect. An ugly old bathroom has been turned into a picture in a magazine!! We especially love the tile work that was done. If you have any work that needs doing we recommend Cross Town for the job. You can trust them."

Barndominium Builders FAQs, answered by experts

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

The term “cottage” is subjective, so there’s no rigid definition, but it generally refers to a small home with simple and purposeful architecture that embraces nature and focuses on charm over everything else. Cottages are typically 1 or 1 1/2-stories tall, usually with gabled roofs, and are built out of natural materials that help make the structure a part of the surrounding nature rather than something that stands out from it. A big part of what makes a cottage a cottage is the decor, which includes natural materials from the nearby area.

Whether pole barn posts should be set in concrete depends on the soil surrounding your home. If your soil is compact and digging conditions are agreeable, then setting pole barn posts in concrete is an ideal option.

Rather than using a common two-by-four piece of wood for a rafter, you probably will use two-by-six, two-by-eight, two-by-ten, or even two-by-twelve boards. Wider lumber is typically a better choice in a larger building as it provides more sturdiness. Some installers may use wider lumber for rafters near the edges of the roof, where the greatest stress occurs, and save money with narrower lumber toward the middle.

You don’t typically need a permit to build a shed, but it’s best to check with your local city clerk to make sure before you start the project. Every town, city, and municipality can have different rules when it comes to any home improvement project. Homeowners associations sometimes have restrictions on the materials you can use on your property as well.
