Grand Lake Residential and
Commercial General Construction

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!

G2 was prompt and professional. Their service was great and there were no hidden or unreasonable costs. We will definitely use them again.

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! Marilyn and Bob

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.

In comparison, by line, G2's bid is comparable to bids received from numerous vendors; however, theirs came with thorough research into possible problematic items, as well as cost-effective solutions rendering the same (if not better) results. Additionally, research was presented on items to be ordered by consumer, with estimated arrival times as well as alternate options at comparable cost (saving us time, and doing so without even mentioning). The response and overall communication with G2 has been quick, efficient, and unprompted. Quality and ratings exceed that of any other vendor/proposal, and with lower overall cost. Seeing a completed portfolio to include Avon Public Safety Facility, Breckenridge resorts, Summit County School buildings, and the Ritz Carlton Bachelor's Lounge - there is clear attention to safety detail, knowledge of precise executions, as well as a keen eye for aesthetics. Add to all of this a wonderful demeanor and established rapport... Working with Garrett and Sean, never once have I felt the "car salesman" vibe of construction lingo to soften the stark $$'s (typically the case). Bonus: even brought me coffee one day! G2 - definitely an A+ outfit.

G2 helped us with replacing our roof. Jeff was friendly, helpful and always willing to answer all of my questions. He helped us deal with insurance and helped us get everything done seamlessly. Thanks so much. Great company.

G2 did a full-house renovation for us - tore out walls, all new kitchen, all new windows, wood-trim throughout...it was major. And we couldn't be happier with the results. They keep the worksite clean; they communicate constantly; and most important of all they keep their word. A big complex project like ours can go wrong in a lot of different ways. We were so happy that G2 addressed every problem that came up head-on and were always mindful of our budget. They have great subs too. Highly recommended.

Jeff was very professional, and he helped me during a very stressful moment. I would absolutely recommend.
