"Project was well timed and progressed seamlessly through various stages - demolition, framing, installation, finish carpentry and painting so that we lacked access to the second floor for only 1 night. Planning including multiple house calls for precise measurements to maximize dimensions, selecting style options and consulting with lumberyard for stair dimensions and details. The crew was experienced, took pride in their work, and did not skimp on quality or details, independent of time."

"They did an excellent job.  The exterior work was performed a couple of weeks ago, when the weather was nicer, and it was done in a couple of days. (I should note that they have not finished it, to wait until spring to tidy it up and do finishing work on it.)  We have had rain since that work was done, and the family room was dry.  No musty or dampness to the room at all anymore.
The interior work went really well too. He estimated about 3 days, it took 4.  The floor is a bit springy, due to extra insulation and padding being put down underneath it, which is very nice for a floor on a slab. It came out looking excellent.
Dave and his workers were very respectful of us and our home, and enjoyed talking with our 5 year old son who was super interested in watching them.  When it was possible (and safe) they let him watch, and chatted with him.  The guys really couldn't have been nicer.  One day, I was headed to a garage to get my car's starter motor replaced, and one of the guys helped me get it started. He insisted to help me (by going down on the ground and hitting my starter motor with a hammer, which did get it working) even though I tried to get him to not.  
They also put the laminate on a few steps leading down to the family room.  I was unsure about how they were going to do this, and at first was unsure about their suggested solution, but in the end, I really like the look of what they did.
It's been a few days since they finished, I did have to go over some bits here and there, along with the laminate floor to pick up any settled construction dust, which I expected to do.  We've moved furniture back into the room, and it's easily the nicest room in the house now."

"They did an excellent job with painting the interior of our house. We had a really high wall in the stairway, and they had no problem getting to the top of it and did a great job! Would hire them again!"

"The technician did an excellent job. It did take a while to get the repair finished, but that was due to Bertazzoni delivering the parts. I have had multiple problems with this particular appliance. My range now works better than it did when new, but I have a feeling that even if I have continuing problems with it, American Home Shield will just repair rather than replace due to the cost of the range. By the way, I'm not exactly sure of the date of the repair."

"details above, we are still waiting for installation but have used K & K for other jobs within the home, so I trust them and they do good work.  We plan on using them to install wood flooring in the fall.

Custom Home Builders FAQs, answered by experts

How long it takes to build a log cabin depends on a variety of factors, including its size and design, and whether or not you have to clear the land. Construction can take a few weeks for a prefab log cabin on an established site, but up to eight or nine months for a custom cabin on undeveloped land. In comparison, the timeline to build a house is typically four to 12 months.

Green homes are often more expensive to build, averaging around $200 per square foot compared to the $150 per square foot you’d spend to build a standard home. However, green homes can save you money on your utility bills by consuming less energy or creating energy using solar panels or wind turbines on-site. They’re more expensive to build, but they often end up costing less in the long run.

Start by researching local contractors with experience in cottage construction. Ask for references, check licensing and insurance, and review completed projects. Compare multiple bids, making sure each includes the same scope of work. A good contractor will communicate clearly, provide a detailed contract, and ensure all work meets code and safety standards.

One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits.
