"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

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.

Building a new home can be more expensive than buying an existing one, depending on the housing market in your area. Many homeowners still find that building a new house is worth the investment as they can choose the exact layout they want, as well as to choose their own floors, wall coverings, appliances, and finishes. If you live close enough to the build site, you can also stop by to check on the builder’s progress, which can provide some peace of mind that the project is worth it.

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.

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.
