"Jeff came by to quote a basement upgrade going from bare walls and ending with a complete family room, bedroom and bath. He clearly understood the entire process and willingly provided valuable inputs/advice that enabled a better visualization of the space. He turned the quote around in a week and I would highly recommend him if you are looking for a quote to upgrade your basement. In the end we did not go with Truste Construction since the bid was outside our budget."

We are a family and veteran owned and operated business located in Littleton CO. We are your true one-stop concrete, retaining wall, fencing, deck/pergola company. We offer many other services as well. Call Gabriel today for your free consultation at 303.994.2944.

"The work was completed in a timely manor and overall looks good, during the project Gabe tried to change the scope many times, but ultimately did stick to our quote. Once work was completed he requested an additional $600 “because we did such a good job” finally within 90 days of having our fence and gate installed the gate began to sag. I contacted Gabe to give him an opportunity to make it right but he did not respond in any capacity. Moral of the story: make sure the work is 1000% because once peppers leaves they won’t return to fix any errors."

Design Exteriors specializes in large-scale Design and Build projects. Want your backyard to be the envy of the cul-de-sac when you host that Broncos party? Let us "trick" it out with a completely customized pergola, fire pit, water feature, privacy screening & specialty patios to set it all on. Want your home to be the loveliest on the lane? Let us design and install a gorgeous curb appeal revision for you. When you're ready to totally revamp your outdoor space and bring in the experts, we're the ones that you will love working with! We partner with homeowners to help them conceptualize what they want and/or need from their exterior home spaces and then we bring in our expert artisan crews to make that vision a reality. Our designs are characterized by elegant curves and sophisticated arcs we affectionately refer to as "Shoebridge Circles" after the lead designer (and owner of our firm) Cedric Shoebridge. Bricks, stone, and pavers have to be custom-cut to fit into these curves, but we know they're worth it because as we like to joke around the office, you never hear a grandma yell to the grandkids to "Gather Square!" We say, "Gather around," because it's circles that bring families together. We are proud to have an A+ rating with the BBB and have been a multiple Award Winner with Angie's List and Home Advisor. #GoBroncos

"We wanted to decrease the amount of grass and improve the curb appeal of our front yard. Our goal was to increase the size of the driveway, add a walking path, and add decorative rock beds. Cedric came up with the perfect design and brought it to life. He and his crew, including sub contractors, did an excellent job right down to the smallest detail and everything was guaranteed. The work was completed in fall 2024. Spring and summer brought beautiful color that we continue to enjoy in the heat of August. We couldn't be happier with the finished project and have received many compliments. Thank you Design Exteriors for a job well done!"

"I hired Paramount back in 2020 for work on the first floor and appreciated their work so much that I brought them back for the basement (fix/ update after mold repair) and second floor (bathroom and stairs update, new carpet). Like the first time, I really appreciated Ryan's suggestions on style and options, and the various contractors were professional and very kind about working around me and the cats. Ryan was ultimately more critical than me about details and appreciate that desire to do things right and as clean as possible. Would use again!... although that would require a new house at this point. 😁"

FAQs for second story addition building service projects in Boulder, CO

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
