Right Angle Contracting LLC BBB Business Review


Anyone can tell you they're great, we'd rather you hear it from our customers instead

"We couldn't be happier with our experience with Right Angle Contracting. Our project was a full basement finishing, this included a 3/4 bath, bedroom, family room, bar space, along with storage and mechanical room. Seth made a great impression from the start of the bid process. He was on time, professional, and brought some great ideas to the table on how best to finish the space. The bid was more than reasonable, and under two competitors for the same type of work. Seth provided a reasonable time table for completion, even though we would be doing the work over all the major winter holidays. When the work started Seth and his team were very respectful of our home. They kept the work area, and the rest of the house, clean during the project. They worked around our family dogs, and our schedules. Seth was very responsive during the work, encouraged us to continually monitor the progress. We made a number of minor changes during the project, Seth worked with us to make it work. The project was finished about one week after our initial agreed upon time. We would definitely recommend Right Angle for any work. We plan on using them for additional projects in the future."

"We can't recommend Right Angle Contracting enough. We just finished a very in depth kitchen remodel that involved completely renovating our existing 1950's style kitchen as well as creating an entirely new design for our main living area. This project included removal of load-bearing walls, refinishing of existing hardwood floors, adding new hardwood, new trim and doors throughout the entire home, removal of dated coved ceilings, tile work, detailed carpentry, etc etc. Our goal was to find a contractor who would be very detail oriented and hands on, had the ability to help us with design decisions, stay within the agreed upon budget/time frame and maintain a safe living space for our two very young daughters. On top of that, we also hoped our experience with this contractor would be positive so that we would have someone to turn to when the time comes for us to refinish our basement and patio. We found all of that and more in Right Angle Contracting. We lined up meetings with EIGHT contractors - a few well-known larger companies and a few smaller ones, like Right Angle Contracting. Seth stood out immediately. He was the only contractor to bring up a couple important issues we needed to consider - such as upgrading our electrical panel. That would have been a costly surprise had it come up mid-remodel. When asking Seth about the removal of load bearing walls he said it was necessary to seek out a stamped plan from a structural engineer. Almost all of the other contractors response to that question was "Oh... I'll just have 'my guy' look at it." Needless to say, Seth built confidence from the get-go while the others did not. When it came time for Seth to focus on the more detailed aspects of our remodel, such as creating a beautiful built-in bookshelf, he spent a lot of time letting us know what he was doing to ensure the final outcome met our expectations. It's apparent he enjoys what he does and takes pride in not only completing a project but also in making sure he walks away with satisfied customers. To make a long story short (woops... too late!)... we highly recommend this company! We will confidently refer R.A.C. to friends, family and neighbors and we look forward to bypassing the aggravation of gathering multiple estimates in the future. We have found "OUR" contractor."

“I could not have asked for a better job. Seth approached my project as if he were working on his own home. Not only would I recommend Right Angle but my wife and I will be using them again for a future project. The neighbors have been watching the progress and the professional manner in which our house was transformed. I know of three in our neighborhood that will be asking Right Angle for a bid on their work.”

S. Holzwart

“Seth and his team at Right Angle did a full home remodel for us in Boulder. The job was done nicely, and he maintained a timeline that got us into the house on schedule. The job consisted of a full kitchen remodel, 5 baths (including adding a new bath), and just about every surface in the house including flooring, tile, paint, texture, new fixtures, electrical and plumbing. Seth worked with us during the remodel and was open to suggestions on things we needed to change without any hesitation. His team also helped with brainstorming suggestions when we ran into some unknown issues with a fireplace that we needed to re-build. I’d use them for any future work!”


“I would highly recommend Right Angle Contracting (RAC) to people looking to finish their basements. The planning process was very supportive in ensuring that the family’s basement finishing goals were met. Our finished basement included a family room with a gas fireplace, a guest bedroom, an office, a bathroom with a shower, a utility room, and an unfinished storage room with a washbasin. Seth would revisit the projected costs each time we explored adding or removing a part of the basement design. The workers were very friendly, competent, neat, and helpful during the execution. Seth was always available to answer questions. All the subcontractor workers seemed to like working for RAC and worked well with each other. The legal contract process was straight-forward, relatively transparent, and seemed fair. We finished the contract work only a few hundred dollars over the original contract price —- and that was due to our wanting to upgrade and add a few fancy fixtures to the bathroom, family room, and storage room. We finished the work only two weeks behind our original schedule. All the work done passed the inspections. We are very happy with the product as are our friends who have come to visit and used the finished basement.”

D. Risser

“Working with Right Angle Contracting was a very positive experience from start to finish. Seth Dineen was quick to respond with a very competitive quote and open to any new ideas during the job that made it a better project but still kept it within budget and on time. Seth’s staff and subs were always courteous, on time, easy to work with and closely supervised by Seth. We enjoyed the process so much that we added some extra projects right away and are already scheduled for a couple more in the next 6 months.”

N. Reinecke

“Working with Right Angle Contracting was pain free, from start to finish. Seth was always prompt, responsive, knowledgable, thorough and a joy to work with on our deck construction project. He worked with us to solve challenges and brainstorm some great ideas, his work is impeccable and his pricing was extremely fair and reasonable. We couldn’t be more thrilled with the end result, and cannot recommend Right Angle Contracting highly enough.”

L. Fisher

“Right Angle Contracting, LLC and Seth performed the exact quality work I wanted for the exact price that was bid. Right Angle removed wood paneling, refinished the underlying drywall, and remodeled my fireplace over the course of 2.5 days. They were clean and respectful of my property while in my home. There was no haggling on price after the bid was submitted, no attempts to run my price up, and the work was done quickly. If you need an interior contractor, don’t look any further than Right Angle.”

C. Hambleton

“Right Angle finished our basement for us. It was a really small awkward space but they found a way to make it look and feel much bigger than we thought it could. All of the contractors that came into the house were very professional and friendly. They were all willing to answer questions of what they were doing and make any adjustments we had. Overall Right Angle’s customer service was very impressive. Seth responds very quickly and wants to make sure that things are being done to our level of expectations. We did get off schedule a bit but he kept everybody moving and always kept us up to date on what was going on and who would be in our home. We have had other work done in our home and they were not nearly as responsive as Seth was. I would highly recommend Right Angle.”

M. Patel

“Right Angle Contracting is a great company! They are honest, prompt and do remarkable work. We are thrilled with the service we received and the end product. Our deck is gorgeous! Would definelty recommend them and hope to do business with this company again.”

T. Guerra

“We are very happy with our new deck cover!! We have gotten lots of compliments! Seth does very good work and was always friendly and courteous. He made sure we were happy when the project was completed. I would recommend Right Angle Contracting to anyone who wants a GREAT job done. We plan to use them again in the future, if we need something else done.”

I. Beck

"I have a beautiful new master bathroom thanks to Right Angle Contracting. Seth listened to all my ideas and found a way to make it happen. He kept me informed every step of the way and was very helpful with answers as to what would fit in the way of mirrors and lighting. I went over every inch of the finished project and can say that the quality of work is excellent. The project took longer than expected, but I never felt abandoned. Seth communicated with me frequently. I have another project for next spring and plan on using Right Angle again."

J. Kohs

"Our initial meeting with Seth and the bid process to complete our basement remodel was extremely professional. He was upfront about costs, potential challenges and estimated timeline. Seth was honest about being in the middle of several projects when we hired him and gave us a time frame to begin the project that was several months out. It ended-up being slightly longer than we anticipated, however, once work began it progressed steadily. Seth and his subs were friendly, respectful, diligent, and CLEAN (every day the site was cleaned). He was conscious of the challenge it was on our dogs to have workers in the house when we were not home. Seth was diligent to ensure that all construction was proper and to code. He explained why things needed to be done in a particular way and was adaptive to change when new ideas were presented (the scope of work grew during the project). The final walk-through was quite satisfactory (my husband is a professional QA person). We have already given Seth's information to friends and family members and have asked him for estimates for additional projects in our home. He is the ultimate clean-cut, all-American guy - you feel very comfortable having him in your home!"

A. Klein

"Seth and his team at Right Angle were top notch. We started working with Seth prior to moving into our house in February and he quickly responded to provide the appropriate guidance plan design for our basement build-out of an unfinished basement. Once we decided on the design, we progressed with the process appropriately. There were challenges with our city permitting process but we worked through those and Seth and his team provided all of the appropriate checkpoints along the way. Seth is a great communicator, provides great advice and guidance and he wants to make sure that you're happy."

A. Luellen

"Our experience with Right Angle Contracting was very positive. We had a room finished in our basement. Seth explained the process through demolition, framing, electric work, drywall, painting and finish work. He was responsive to any issues or questions we had. He kept us informed as to the progress or any changes to the schedule. The workers were considerate and kept the work area clean. The finished product turned out great - we are excited about our new room."

A. Kjellerson

"I couldn't be more happy with not only the quality but the professionalism of Seth and his Right Angle team. My wife had to move out to Colorado before me so she had to handle the basement remodeling, something I would have normally done. All of their employees/subs were very courteous, especially in light of our situation. I will use Right Angle Contracting for any construction project I have in the future."

K. Dyer

"We had Right Angle Contracting update our two baths and remodel the kitchen. We are very pleased at the process and outcome. Seth guided us on the process. He was helpful but never pushy in his opinions. Seth and Ryan were great to work with. Thanks to them we were never stressed and ended up with a wonderful "new" home."

D. Simansons

"I found Right Angle from the BBB site, emailed them and Seth quickly got back to me. Seth came over, surveyed the space, made some great suggestions and helped us visualize everything through computer simulation. The quote was very reasonable compared to other contractors. Right Angle was easy to work with and completed everything we asked with no hesitation. The basement turned out great!"

C. Magee

"Right Angle Contracting was honest, fast and easy to work with. They communicated well at every step of the process, worked with my insurance company, and did everything they could to make sure the job was done on the timeline we had landed on. They are a great company, and I will work with them again on any future projects in my home."

G. Avedikian

"Working with Right Angle was great. We spoke with many contractors while getting quotes to replace our roof and skylights, and Seth stood out as being recognizably trustworthy right off the bat. Never for a minute did we have to doubt that Seth would keep his word on something or fail to back up his work, which was excellent, and that made this whole process a ton less stressful than it could have been. Seth even spent time fixing our AC when it went out after the roofing work. While the AC going out could have been unrelated to the roof work, the fact that he was willing to spend the time to fix it speaks volumes of his character. I would highly recommend Right Angle, and will certainly go to them first if we need any work done in the future."
