We used G2 for a major home renovation. Everything from demo to adding extra living space to completely rebuilding the entire main floor-kitchen, bath, flooring, electrical, plumbing, painting, etc. They are honest, hard-working and easy to work with. No home renovation project is without complications, unexpected obstacles and setbacks. G2 stuck with the project until every last detail was handled. Their integrity is beyond question. If something was not right, they made it right. A rarity in this industry to find a company that stands by their work, their word and their workers. Derrick, Nick, Jose, Jeff…and the whole team…great to work with! We will continue to use their services for our home and business properties.

G2 Construction built a new 18' x 18' deck and awning for us to replace an old damaged structure. The awning is open beam, heave timber construction and the deck flooring is solid premium Trex. The finished product is beautiful and we couldn't be happier. I'm a retired construction manager of 40 years, and you can take it from me that even though this was some what of a specialty project, it was a no-hassle dream working with this contractor. All their employees and subs we're great to be around; knowledgeable, polite and accommodating. The business owner, Derek, managed the project well, and the field superintendent, Jose, is a near construction perfectionist. My wife and I are proud to recommend G2 for any residential/light commercial construction work. Sincerely, Steve & Jennie

We hired G2 to complete a commercial remodel project in a 40 year old building in Longmont. G2 was excellent in every way. From beginning to end, they were punctual, professional, thorough, responsive and completed quality work. G2 gave us a fair bid on a optimistic timeline. Due to their fantastic coordination with their subcontractors they stayed on schedule for everything that was in their control. We had some delays due to unexpected findings above the drop ceiling and additional specifications we had to add at the last minute. G2 was always a part of the solution to unexpected situations and worked very diligently to get the project completed to our satisfaction. Special thanks to Aaron and Dennis who were great to work with at every step. I highly recommend G2 to anyone looking for a quality contractor. I would definitely hire them again.

G2 did two separate remodels for us during the Covid pandemic. The first remodel was our kitchen and main level trim and paint, as well as new railings on our stairwell. They did a fantastic job with it. Lots of attention to the small details that make it look so professional. They also had to add a beam to replace a post and took care to wrap it in wood that matched our cabinets. Despite all of the challenges with getting inspections at that time, they managed to stay pretty close to our original schedule. We brought them in again to do our master bath, and upstairs trim, paint, and carpets. They did an amazing job with the tile details, cabinetry, and fixtures. They took a lot of time getting the barn door lined up and working right. They came back to touch up the details at the end so it was perfect. Communication was good throughout the projects, they asked questions when necessary, and they shared photos of progress. I would recommend them highly.

G2 Construction is a highly reputable company. G2 replaced our roof this week and did a fantastic job! They were fast, efficient and professional. We had some issues with our insurance company not wanting to cover the cost and Jeff Carlson from G2 went to bat for us and contacted our insurance company. Jeff's extremely honest, hard-working and professional! He stayed in constant contact with us and when the insurance company approved our claim, he had a team out in a short period of time and we received a high quality roof that will last for years to come. No matter your need, G2 is the company to call. With owner, Derek Griess and every employee you can expect great quality work at fair prices. They are dependable, trustworthy and reliable!

We hired G2 to coordinate and complete multiple projects on our new “1965” home. We could not be happier! Front and backyard custom fences, exterior walls cut and windows installed, an upgraded electrical panel and other needed upgrades too numerous to lust. Nick, Jose, Ari and the crew are outstanding! Creative, kind, problem solving wizards chock full of integrity and responsibility. We will be working them for years to come!

G2 replaced the roof and gutters on our private, Christian school. Around the same time, they also did the roof, siding, trim, gutters, and exterior paint on our house. For both projects, the crews did great work and were so fast! Our house was done in one day and our 50,000 square foot building was done in just under 2 weeks even with bad weather. Jeff kept us up to date with every little schedule adjustment (it’s been a rainy spring!) and was honest and straightforward with everything. Jeff was so knowledgeable about working with our insurance company and knew where typical oversights could happen and worked to prevent them. I’ve heard roofing horror stories from other people, but both our projects could not have gone smoother. I highly recommend Jeff and G2 Construction for residential & commercial projects!

We started working with G2 on a roof replacement. They worked closely with our insurance company to maximize the claim coverage. Jeff oversaw every step of a complicated process (solar panels had to be removed and replaced and we replaced a swamp cooler). We were so impressed with their work, we then hired them to completely re-do our backyard, with a deck removal, brand new gorgeous concrete patio, new drive way, new sod in the yard and yard edging with gravel. They exceeded our expectations with professionalism and attention to detail. We will definitely call for any future project needs!

Jeff was a real pleasure to work with on our roofing project...from his first visit until the completion, he was friendly, patient, professional, and thorough. The roofers were very professional, fast workers (less than 7 hours from beginning to completion), and friendly. Our yard area was completely clear of any trash when they finished. We are beyond pleased with the entire project and would definitely recommend G2 Construction LLC for your next home project.
