We're in process of getting bids on a deck/exterior office space remodel. They were very responsive to our initial request, and we talked to one of the owners of the company via phone and in person within 7 days of our outreach. The project is probably too small for their level of services, but we will definitely consider using them for a future, more complex interior home renovation. They were very nice and giving of their time and expertise, and their build process seems very professional and polished. We had an excellent experience with them.

I used Thomas Custom Builders to construct a studio addition over my garage in 2017. That experience was so positive that I used them again for a complete kitchen remodel in 2021, as well as repairing some fire damage in 2022. In all cases, they built exactly what I was looking for, and I am very happy with the results. I'll definitely use them again.

I spoke with Cole today and right off the bat I got a good feeling. Very welcoming professional and polite. What won me over most of all was his honesty which is a rare find now days especially in that business. I am so very pleased with the way I was treated and will recommend this place in a heartbeat. Thanks so much for your help Mr. Cole

I had an incredible experience with Thomas Custom Builders! They not only added a beautiful addition to my house but also completely transformed my master bathroom into a luxurious retreat. From start to finish, their team was professional, efficient, and attentive to my needs. The craftsmanship and attention to detail exceeded my expectations, and I couldn't be happier with the results. I highly recommend Thomas Custom Builders for any home remodeling project!

From initial design meeting to project completion Thomas Custom Builders kept promises, delivered outstanding work on time and on budget and exceeded our expectations in every way. Their on site team did everything they could to keep the work place clean and tidy so as disrupt our home life as little as possible. Team leadership kept us informed and made sure our questions were answered promptly. They are excellent tradesmen with exceptional skills. I’d give them 10 stars if I could.

We have had several contractors over the years with middling results. We found TCB last year for a 400 sq ft addition to our house. We looked at three contractors and selected TCB based on reviews. From start to finish, TCB work was absolute perfection. This year a medical problem required a master bath renovation. TCB was the only quote we asked for. We knew they would do the job to the highest standards. They also worked around my illness which left me fatigued and immune compromised. We asked that the workers not smoke and they complied. They wore masks continually while in the house and cleaned up very throughly at the end of each day. In addition, the workers and supervisors soon felt like family. I would happily give them my keys if I were away for an extended period. When they finished, the results were absolute perfection. My bathroom is much safer and is beautiful. If you are thinking about a remodel do yourself a favor and call them first.

Thomas Custom Builders recently remodeled our unfinished basement. We had originally hired them to remodel our master bathroom but when COVID hit we shifted our focus to our partially unfinished basement. They had no problem with the change and quickly designed our basement for secondary living and room for extended guest stays. We truly appreciated the professionalism, workmanship and, above all, cleanliness of the TCB team. They went above and beyond to clean up each and every day. They wore masks and kept their distance from our family. They fielded questions from subcontractors so we didn't have to be unnecessarily exposed. The space itself turned out beautifully and has already proved invaluable. When our teen was recently exposed to COVID he was able to very comfortably isolate until he received his negative diagnosis. Even in these times of uncertainty, we wholeheartedly recommend Thomas Custom Builders if you are considering a remodel.

I am taking bids for an addition. I wanted to consider this company until I was told their process is to give me bid range on internet and online back and forth without ever coming out to set eyes on the property and the bid would be adjusted later as details got fleshed out. Seems lazy and risky. Once committed the costs could go anywhere. I declined and moved on.
Response from

"Thank you for your feedback...we are always looking for ways to improve. There seems to be a misunderstanding regarding our Process. While we have started offering virtual consultations if a homeowner is uncomfortable with us being in their home, this does not take the place of visiting the property when it is safe to do so. Regarding costs, the Design-Build approach is a collaborative one. We work hand-in-hand with our clients throughout the entire Process to fine tune the costs involved with a project. This allows us to produce a guaranteed maximum price (GMP) which guarantees homeowners that the cost of the project will not exceed the agreed upon GMP. More detailed information on our Process was provided via email. This information can also be found on our website at ThomasCustomBuilders.com."

We selected this company because we wanted to renovate our master bathroom and add lighting in certain other rooms. They could do both for us. Having recently been through a master bathroom remodel in another house in another region, we knew what we were getting into, and what we wanted. They gave us an early estimate, which seemed reasonable, and wanted several thousand dollars to draw up the design (note: we didn't change the floor plan and we knew basically what we wanted). We met with subcontractors to pick out vanities, tile, and granite. We already had picked out our hardware and fixtures. After this, they gave us our actual estimate - about 60 percent higher than their original estimate! We tried to make sense of their rationale but at the end of the day there was a high dollar amount we could not account for, despite repeated questions asked by us. We did not select the highest end extras that would have escalated the cost. At the end, we went with another contractor (who came in at our original estimate and delivered a beautiful product), selected an electrician on our own, and chose to forego our money for their (TCB) design fee.

Overall this was a bureaucratic, slow, and overpriced process. Entered into a design agreement for the remodeling of a kitchen, deck, and two bathrooms. They required a signed design agreement and $4000 for them to perform preliminary design. Based on Angies List reviews and other sources, they appeared to have a good performance. Here is the timeline of events, referenced to when the signed agreement occurred: 3 weeks for measurement meeting with promised line drawing within two weeks; at 7 weeks provided an apology for not having drawings complete and promising completion within two weeks; at 11 weeks provided complete line drawings; at 12 weeks provided preliminary estimate with estimated cost. This timeline included multiple attempts by myself to ask for status, push different team members to coordinate with each other, and an overall perception that I was having to manage their team for them. The purpose of this builder was for them to manage all these efforts as I was paying them for that service. I attributed these issues to a very bureaucratic process they have set up and dysfunctional coordination among their team and subcontractors; even before the construction work started. They appear to overall have a very defensive posture throughout the process through their required legal agreements and generic corporate-like responses that were not fulfilled. They appear to be resting on their laurels of possible past accomplishments and are trying to deal with the symptoms of their current problems through defensive actions. In comparison, I went with another local provider that was able to get to a preliminary design within three weeks, did the work with no design fee, and their estimate came in $50K less. This comparison shows a lack of desire from TCB to serve their customers and inefficient processes. As a final example of these issues, when I informed them that I was going to go with another option, which was before we had finalized the preliminary design and did their "trade walk-through", I asked if any of the $4000 design fee would be returned. They said they would provide $1000 back as a "good faith payment" but required my signature on a long, legal Non-Disparagement Agreement. This document would effectively squash any reporting of their problems and provide a silence payoff of $1000. This is very shady in my opinion and likely led me into the trap that I faced when doing my due diligence online reviews of their work. I decided to forego the $1000 and instead provide a warning to any people considering using TCB. I do not want them to fall into the same trap and perpetuate hiding their failures.

"Our goal is to provide the very best service and we are always looking for ways to improve. While we disagree with the stated timeline, we can appreciate the frustration with the time it takes to get from vision to working layout. Designing a project, which is what we were contracted to do, can be a lengthy process. From the measurement meeting to final pricing is a minimum of 12 weeks. This timing can vary greatly based on size of project, client response time and unforeseen circumstances including vacations, work schedules and holidays. We try our best to communicate this from the initial consultation but will make a more concerted effort going forward. We value all feedback, positive or negative, and use it to examine our current procedures."

Rick and his partner Dave met with us numerous times. Provided great solutions (cost savings) and were frankly straight up honest! While issues with neighborhood design review caused us to postpone the work, I felt they were a solid A+ firm. No, not the cheapest but thorough.

We had a wonderful experience working with Thomas Custom Builders (TCB) from start to finish on our home addition. We added a master bed and bath, unfinished basement, and screened in porch. First and foremost, we went with TCB for this renovation because we felt like they provided high quality services at a competitive price. We felt very comfortable undertaking a big project like this with TCB because unlike some of the other builders and architects we met, TCB listened to our ideas and concerns and helped us to visualize exactly what we need in a renovation and within our budget. They worked with us patiently through changes in ideas and scale of the project. Then throughout the actual renovation, the TCB staff were amazing. Brian was onsite the entire time, overseeing every aspect of the project, with absolutely no issues. It was great to have the same person there every day and it was very clear that he knew exactly what he was doing and what we wanted/needed. Work was always done within a reasonable time frame and with high quality. The TCB team finished everything within 3 months, which was even faster than we had even anticipated. We would absolutely recommend TCB to our family, friends, and neighbors and use them again.

In short, things went GREAT, and I can whole-heartedly recommend Thomas Custom Builders (TCB), which is a "design-build" firm. Here's how things went: Firstly, expect that they have a backlog, and it may take a while to get to your project - probably because their reputation proceeds them. It took nearly 9 months between when we started with them on scoping our our project to when we broke ground, however we ended up with a design that worked. Through that phase, we worked with TCB on what goals we wanted to achieve, and what our budget was, and they designed to achieve as much of our goals within our budget. During construction, TCB promised to have a foreman who spoke fluent English on-site every day, and they delivered on that. This stood in pretty stark contrast with some of my previous contracting experiences, where the project could languish without seeing anyone come to the site. With TCB, the project always moved forward - sometimes it moved rapidly, with multiple trades on-site - sometimes it moved moderately, with the foreman and a couple helpers - and sometimes it was just the foreman handling things himself - but it always moved. TCB also is the kind of company that won't nickle and dime you. If something small is missed in the project scope that is needed to really complete the project, they'll do it. Don't expect them to shell out thousands of dollars in that respect - that would be a change order (which I had one) - but at the end of the day, I very much got the impression that they really took pride in their work and wanted me to be happy with the end result, which I am. TCB estimated the job would take between 3 to 4.5 months, and they completed in 4 months. I had one change order to connect my concrete/flagstone walkway to my stairs, which we had missed in the scope and was too big of a cost for TCB to absorb ($2.5k), however that was the only overage, so all in all we stayed on-budget. Things that we got done in the project: - Bumped out front to add walk-in closet and much bigger master bath to master bedroom. - Reconfigured entryway with a foyer/mudroom and semi-open staircase to attic. - insulated attic. It's still unfinished, but much better for storage. - new roof w/ 30 year shingles - widened dining - family room entry to be open concept. - re-did fireplace wall with built-ins, stone tile, gas insert - new paint for most of first floor - refinished all hardwood. One thing that we did to help out is that we completely moved out of the first floor as well as most of the attic stuff into a POD. TCB will readily tell you that they aren't professional movers, so go ahead and hire a professional moving firm to do that for you to clear the way for TCB to do their work. We used 2 men and a truck and were very happy with them.

We are extremely happy with the work done by Thomas Custom Builders (TCB). Overall they did an amazing and outstanding job! They had a contractor on site, on time every day. Brian S. was professional, helpful, patient, hard working and skilled both in managing subcontractors and doing work himself. I trusted him with our home and would work with Brian/TCB again easily. I have already recommended their company to others. TCB renovated a few parts of our house, added electricity to a shed and added an entire master bedroom suite on an additional floor (adding approximately 550 sqft to our house). They finished earlier than expected. Our neighbors couldn't believe how fast the addition was completed and how well done. Any additional costs from the original budget estimate were due to our choice to add more work. I waited to write a review. I wanted to live in the addition for a little while to see how everything holds up. We have had only minor things arise and have been very pleased with the responsiveness of Brian and TCB to come back out and check on things. They came back to add a bracket to a new countertop that moved slightly, they shaved a door that was sticking as the weather changed, they fixed the damage done when carpets were installed by another company, they arranged for a rep from the hot water heater company to come out and fix a noise issue, all done at no additional cost to us. I have worked with contractors before but nothing on this level. It wasn't perfect, there were concerns that came up. I had to learn that this was major construction and with major construction comes mess. Brian and his team addressed our concerns and remedied any issue fairly. With so many negative stories I've heard from people who worked with other companies, I am so very thankful that we had such a good experience and ended up with such an amazing master suite and changes to our home. We love it and we receive many compliments. We chose to work with TCB because they came highly recommended by a neighbor who had similar work done and were very satisfied with their outcome.

I'm embarrassingly late writing this review but my endorsement is nonetheless heartfelt! I hired TCB last year to rework and remodel a small master bath in my 30-year old house and also to finish out a stubbed-in but completely unfinished basement. They did an absolutely fantastic job, from the early planning and design work through random finishing details. They created a plan for both spaces that considered the age of the house, pre-existing plumbing, hvac and electrical systems, and usability of the space. They insisted that all work be done to code, declining even to consider items that wouldn't pass an inspection. They hired good reliable contractors who showed up on time and got the job done. And they assigned me a regular supervisor who was on site every day to oversee everything and keep me appraised of progress, challenges, and timelines. They were not the least-expensive contractor I talked to, but in the end I feel I got a really high quality job that I don't have to worry about and can be proud of. I was very happy to work with Thomas Custom Builders and highly recommend them to others.

Hiring Thomas Custom Builders for this job was the smartest thing we've done in many years. From the first call I made to the final inspection, they were nothing but professional, skilled, courteous and (appropriately), funny. They understood what we wanted, we understood that no plan survives contact with reality, and whatever minor snags we ran into, we worked them out. The forman, Clifton, was a delight, as were Adam and Kevin, and Rick Thomas and David Holmes were a joy to work with. We are more than delighted with with finished room (and the insulation and drywalling of thte garage part), and though it's been more than a year, nothing has gone wrong that needed their attention, and the room continues to be a great pleasure to use and work in. Would definitely hire them the next time we do a major renovation.

I never submit reviews online, but my family had such a great experience with Thomas Custom Builders that I wanted to share it. We restructured and remodeled our master bath, guest bath, and bedroom, and love the results. Initially I was concerned about price, but over the course of the project I realized how much value we were getting. The design and outcome itself is excellent, but the experience working together was as noteworthy. Rick, Dave, and team put us in touch with an excellent network of designers and suppliers that made a huge difference in designing our ideal remodel within our budget, and that worked well together to stay on schedule and put as little work on us as possible. The onsite team was a pleasure to work with and completely responsive to any questions or requests, and they worked seamlessly with the electrician, tile, and plumber. Even their front office invoicing contact was invaluable in guiding us through the project with recommendations and clear expectations. I'd recommend this team to anyone.

We could not be happier with Thomas Custom builders for our project. They did a great job turning our wish list into reality. Their architect did an amazing job translating our ideas into a workable plan on the first draft. The builders themselves are excellent, going above and beyond to ensure a quality build. We had a short schedule (abut 4 1/2 months) and they met the timeline, and stayed on budget. We were well informed throughout the process, were able to make some changes without any hassle during the project, and now after 1 year everything is working great. They even worked with us when we had to move back in prior to completion. I would highly recommend them for any project.
