"I couldn't be happier with Joe and his crew.  From first contact and the time we met to get an estimate I could tell right off the bat he knew exactly what he was talking about, and was very professional about everything.  I met with 2 other contractors, and even though Home Facelifters wasn't the cheapest, I knew that they would get the job done right and on time.  They dealt with all of the city inspectors and dealt with pulling all the permits, they helped me pick out many of the different items for the house like the cabinets, counters, appliances, flooring, and even colors for the walls.  There were some things that I thought I wanted a certain way but Joe was always willing to try and explain why another way might be better, which I do appreciate.  The payment process was very simple, we did go over our original estimate, but he had told me upfront there was a chance we would find things behind the walls that we couldn't predict, and I was prepared to possibly go over by a certain amount so that wasn't a problem.  The work was done very quickly, and the quality of everything is great.  I will definitely be using Joe and his crew on future projects of mine.

"We recently had a complete roof replacement. Before proceeding, we did comprehensive research of area companies and Vista came out on top, with good reason! All appointments were not only on time but were extremely punctual. We met first with Product Specialist Holly, who was enthusiastic, very knowledgeable and helpful. While at our home assessing the proposed job, Project manager Rick explained the entire process in layman's terms. The day of the job, Project Supervisor Marc arrived early and went over the entire job with the crew. All company representatives left us with a business card with their cell #'s to call if we required anything. The installation crew was amazing. They arrived early and began immediately. They were no nonsense, very focused and, worked like a well oiled machine. All Vista team members were polite and respectful of my special request to be cognizant around some of my more cherished trees & shrubs. Vista was fastidious in their care for my home and lawn, not one speck of debris was left behind. Vista, the installation crew, company representatives, everyone, exceeded our expectations. Vista stands behind their work and products. If you wish to relax after a major home improvement project knowing the job was done correctly, you will want to consider Vista. Dan & Kim Belchertown"

"I hired Glenn in 2008 to reside my 1865 house with cedar clapboard shingles and to raise the roof structure covering our kitchen and bathroom.  He also gutted and remodeled the kitchen and bathroom.  This was a big job.  Glenn handled all of the necessary permitting and help us with the design to the point of even attending a Historic District Commission meeting to obtain the necessary approval.
In 2012 I hired him again to reside and re-roof our detached garage.  And now we are working with Glenn on a design for some additional remodeling of our living room area.
Glenn is excellent at what he does.  He is reliable and has a passion for quality.  He wants to make sure his customers are satisfied.  He is a perfectionist who tackles his jobs as if they were on his own property.
I highly recommend given Glenn the opportunity to bid on your job.  You will not be disappointed.

"I cannot speak highly enough of Tom and Brad Green of Colonial Restorations. We have lived in our antique house for 16 years now, and like most old homes, some of its previous repairs were good, some not so good. Tom Green worked on this house for its previous owners, and his work was, by far, the best in the house. So, we continued to use Colonial - Tom, then Tom and Brad - as we learned the ropes about caring for an old house - our first house, old or new. Over the years, they have replaced sills and posts and beams, and rebuilt parts of our loose stone foundation. Most recently, they replaced the last original posts in our basement, (one of which was a tree trunk still with bark on it), including pouring new custom footings, in advance of our finally cementing the dirt floor. The work here is never easy - nothing is level, nothing is square - but the Greens' end result has always been beautiful - strong and made to last. Their prices are fair and without hidden costs....maybe not the lowest bid you might get, but you know it's a real bid that they will stand behind. They triage projects for us, giving us an idea of what other items will likely need attention in the next few years. We're not done with this house yet....we've never won the lottery, and there's always another repair..... and plan to use them again soon. I feel confident knowing that the next owners of this house, whoever they might be, will see the quality of the work and know that we cared enough to have the right people help us with the ongoing repair and maintenance of a 275+ year old house. I am a real person, a real customer, with no ties to the company, and was more than happy to write this review."

"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."

"Mr. Davis was there daily to supervise and work with his subcontractors.  He ensured that each step of construction was performed in a timely and high quality manner.  Mr. Davis can perform almost any type of construction from commercial to residential and has won numerous bids to construct Walgreen stores throughout the South and Mid West.  He has also built many Krispy Cream Shops in the same geographic area as well as built the Master Theater for NASA in the Houston area.  Mr. Davis and his crew are extremely detail oriented and provide the consummate level of customer service.  As a Master Carpenter with over 40 years experience, there is no job big or small that he cant handle.  Mr. Davis ethics are unquestionable and you can absolutely count on his word.  I would highly recommend Mr. Davis to anyone who needs home repairs, renovations, room additions and new construction.  When it comes to price, quality, customer service and ethics, Davis and company cannot be matched.

Custom Home Builders FAQs, answered by experts

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.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

Construction typically takes 3-6 months, including site preparation and assembly.

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.
