"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."

"????? After another company came in and completely messed up our deck project, we were frustrated and unsure who to trust. Thankfully, we called Modern Building & Contracting, and honestly, we only wish we had found them first! James and Mike came out, listened to our concerns, and immediately put us at ease. From start to finish, they were professional, knowledgeable, and committed to doing the job right. The quality of their workmanship exceeded our expectations, and the finished deck turned out absolutely beautiful. My family and I couldn?t be happier with the results. It?s clear that they take pride in their work and truly care about their customers. If you?re looking for a reliable contractor who delivers quality craftsmanship and excellent customer service, we highly recommend Modern Building & Contracting. Thank you again, James and Mike?we love our new deck!"

"As a local landlord- (I own and manage five multi-unit properties) I am constantly balancing between getting a job done as quickly as possible, getting a job done for a fair price, and getting extremely high quality work for my money. After having worked with multiple contractors I am excited to have found Greenspun Building and Design as they manage to consistently perform above and beyond my exacting expectations. They are attentive of my needs, respectful and accommodating of my tenants and most importantly their work is of top quality. In terms of bang for my buck I have not found anyone who can beat them. For example they remodeled two of my bathrooms last year and as expected I have never had to look back- they still look like they were built yesterday despite a year of heavy college student use. I can't recommend Greenspun Building and Design enough."

"Loay Jabbar provided the information I needed quickly and clearly. I immediately signed up for full coverages for our two homes because of the discounts offered and because of the quality of service that Loay is saying and promising Choice Home Warranty provides to its customers. I have bad experiences with other home warranty companies so I am hoping I found the best company that would deliver the best service."

Custom Home Builders questions, answered by experts

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.

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.

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.

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.
