"They weren't too bad but I think they could have done a better job. They did a couple of different jobs. I own rental property but all the 3 buildings are on the same piece of property where I live at. So far it seems they've done the trick as far as solving problems like pipes freezing out, that kind of stuff. Unfortunately my house itself can't be insulated any more than it already is but what I was trying to get at, like trying to get rid of dross and making sure that doors seal up well, things like that, I think they could have done a little bit better. If their prices are as reasonable as right now, I'd probably use them again. They could have tried harder to insulate my apartment. There are places they could have done it because we had a section of the house redone. Our kitchen was remodeled and they could have done it but they didn't. They could have been more attentive to detail. My house is not a new house but its also not a real old house either, it was built in the 40's so something needed to be looked at to make sure that the draft was kept out not just from the windows and walls that were insulated but also the door, the door jambs, making sure the door fits tight and all that kind of thing."

"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.

"Preston of G-1 Plumbing performed the services and addressed the toilet & drain problem. He was unable to stop leak(made it worse) & submitted his recs to Choice Home for review. I was unable to understand Choice Home's response regarding the faucet leak. Their review stated faucet needed to be replaced BUT it was under "builder's warranty." I built this home in 2005. There is no "builder's warranty" now. I cancelled the proposed work order & paid out-of-pocket. A Friend, who was familiar with my builder and knows faucet components, came to my home, adjusted/cleaned the faucet cartridge and stopped the leak. The CHW tech, Preston, is conscientiuos, however, IMHO lacked the knowledge & experience to stop my leak. Home Warranty Companies, at least in my area, hire owner/operators who need the work to build their business and are NOT the most experienced/knowledgeable & are willing to work for less money. In my experience, Home Warranty Companies want the CHEAPEST resolution, not the BEST. I would recommend G-1 Plumbing for most plumbing issues."

Barndominium Builders FAQs, answered by experts

Building a tiny house is the least complicated way to build, especially if you’re tackling the project as a DIY. The smaller size means less complex plans, more straightforward utility installation, and fewer ways to make costly errors. Tiny homes still need to conform to building codes and often have other applicable regulations, so be sure to get the proper permits and confirm your build is by the book.

The pro you need to hire to build your shed depends on the shed you purchase. A local handyman or general contractor can help build a prefab shed for you. However, if you’re looking for a custom shed, contacting a shed builder near you is the best option. Make sure you get quotes from 3 pros to decide on the best pro for your job. 

Yes, you can use a storage shed several ways, including as a chicken coop, but you'll need to make some modifications. You will have to add a chicken door, roosts, ventilation near the roof, mesh on the windows, and insulation if you live in a colder climate. Additionally, you’ll want to ensure that the shed is predator-proof so no other animals can harm your chickens. You should also add a run and nest boxes to your shed.

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.

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.
