"Terbrock's team showed up on time and did the work professionally and carefully -- like it was their own personal home improvement project. At the end of the day, Tom Terbrock himself showed up to make sure everything went well. The price for the work, including removal of existing fixtures, installation, and clean-up, was more than reasonable."

"We love our new shed! We hired Tittel Construction to build a custom shed on the site of our previous shed. The concrete pad was there already but has a definite slope from a previous tree growing too close. Connor was able to not only build a great shed, but also make it level on a sloped foundation! He was very patient and helped me design, through Pinterest pics and my rough drawings, the perfect shed including 10 reclaimed windows. I’d highly recommend Tittel Construction."

"Sentri Homes provided the most professional flooring service I’ve ever had. The LVP installation turned out absolutely beautiful, and I was amazed at how quickly everything was completed without sacrificing quality. The crew was fast, accurate, and extremely detail-oriented from start to finish. Everything was installed cleanly, precisely, and with real craftsmanship. The entire process was smooth, efficient, and far beyond what I expected. I would absolutely recommend Sentri Homes to anyone needing flooring installed."

"Chris and his crew made sure they knew my style and what I was looking for in my family room makeover. He built our mantle and shelves from scratch and we couldn't be happier with the way in turned out!!"

"1. Jonanthan gave me the best and most honest price among the quotes from 5 contractors. 2. He worked very carefully in this job. I am very satisfied on the quality of the installation. I was trying to find the issues on alignment and spacing but I could not. 3. The most impressive part for Jonanthan is he stayed late on Christmas Eve to finish the job and kept his promise on working days. I haven’t seen any contractors like him who is so dedicated to the job and schedule. 4. The only recommendation is to invest a little more to upgrade tools to improve efficiency. But I believe it won’t be a problem in future as you would earn many customers because of your work attitude. Overall I highly recommend Jonanthan and I hope his business is better. I will certainly return if I need anything to be done in future."

Custom Home Builders questions, answered by experts

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.

How long it takes to build a custom home or rebuild a home after a disaster varies depending on many factors, but averages between seven and 14 months. Smaller homes or homes that don’t need a re-poured foundation may take less time to build than larger homes or homes without an existing foundation. Material availability, contractor schedules, and permit and inspection timelines can all affect how long your house takes to build.

A carriage house is a freestanding building, while a townhouse is connected to other units. A townhouse is a full single-family home and typically shares a parcel of land with other connected homes. A carriage house is rarely used as the sole single-family home on a property and is most often an additional building sharing property with a traditional single-family home. 

Craftsman-style homes are predominantly found in the Western United States, specifically in Southern California, where the style originated. Since the climate was mild and there was access to plenty of natural resources, Southern California became a hub for this style at its inception. That being said, if you consult with an architect near you, you can have a Craftsman-style home anywhere.

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.
