"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."

"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."

"It went excellent!  Hi Tech Construction Co gave me a detail estimate of the job.  And compared to other estimates I received from several other companies, Hi Tech's was the most reasonably priced.  Hi Tech also gave me a timeline of the job from beginning to finish and they were right on target.  The crews showed up on time and carried out the job like experts - they surely looked like they knew what they were doing.  I noticed that they were very concerned about the safety of our neighbors, anybody passing by, their crews, and us.  They also cleaned everything right after they finished their job.  I was really happy with the timeliness and the quality of their job.  I will definitely strongly recommend Hi Tech.  I do not think you can go wrong with them.

Barndominium Builders FAQs, answered by experts

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

American badgers sleep in the burrows they dig, which can be extensive, featuring multiple chambers and tunnels. Badgers prefer to excavate their dens in open grasslands, prairies, and fields where the soil is easy to dig. They are solitary animals and usually have several burrows within their territory to use as needed. These underground homes provide them with a safe and secure place to rest during the day and to raise their young.

It may be tempting to DIY the construction of a swing set to save money, but we don’t recommend it. Since children will use the swing set, the entire system must be solid and safe, meaning the cost savings aren’t worth potentially endangering them. Plus, most DIYers will have to build their swing sets out of wood, which won’t last as long as metal or vinyl and introduces the risk of splinters. Instead, hire a local playground equipment installer to ensure the swing set is built safely and efficiently, setting up your kids for fun for years to come.

While prices fluctuate because of increased demand, fewer supplies, and engineering time, OSB generally remains more affordable than plywood at $1 to $2.40 per square foot compared to the $4.50 to $10 for plywood. Cost is only one factor you should consider when deciding between OSB and plywood.
