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."

"I would highly recommend Stud Construction. The general contractor was on the job every day, sometimes twice a day. They are experienced, reliable, see the big picture, have great ideas and approach challenges as opportunities for solutions. They constantly demonstrated integrity and persistence. They have excellent subcontractors who do painstakingly great work—on time, safety conscious and adaptable. It was a painless project and the end result is perfect."

"Mario, the technician, seemed very nice and knowledgeable The $49 quoted trip charge turned into a $220 diagnostic charge not including any service. He wasn’t sure why water was appearing on the floor, but felt it may be due to some clogging of a PVC drain tube. He said it was not possible to simply clean it out, but it should be replaced at a cost of another $250 (for a pipe?). We declined. We subsequently had another repairman come in who said there is no problem cleaning the tube and did so. The material clogging the pipe is shown in the photo."

FAQs for second story addition building service projects in Westminster, 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.
