Deck & Patio Installation

We had DG and his team do a bathroom remodel and a remodel of a salon in our basement. Excellent craftsmanship done in a very timely fashion. If you are looking to have any work done around the house I recommend you give them a call.

The overall experience was defined by excellent execution and a thoughtful approach at every turn. I appreciated the dedication that was evident from start to finish, creating a highly rewarding journey. The outcome was superb and left a lasting feeling of satisfaction.

I highly recommend DG Allen Construction. I was referred to Greg Allen in 2019 by a trusted friend. I hired Greg to do an extensive renovation project at my home. The project included adding a family room, a screened porch, a deck, as well as renovating the existing main floor to include a complete renovation of the kitchen, relocating the bathroom and laundry rooms, creating a second entrance to the home and changing the main floor plan. The final project turned out exactly as I had hoped! During the course of the project, Greg demonstrated an excellent knowledge of everything related to building and renovations. Since then, I have continuously used Greg for additional projects, big and small. I have gotten to know him and his employees over the years. I find the three of them, Greg, Rick, and Jimmy, to be honest, trustworthy, and genuinely good people. I trust them in my home, even if I am not there. I’ve also been very happy and impressed with the subcontractors that Greg chooses to use – also very good knowledgeable people. Greg ensures all work is done correctly. Greg ensures the work areas are kept clean and he is always mindful they are in someone’s home. During the many projects over the years, Greg has always accommodated my changes mid-project without hesitation and always with a smile. He, Rick and Jimmy are pleasant, personable and always professional. I believe Greg‘s prices are fair and reasonable. I would highly recommend DG Allen Construction.

DG Allen Construction did an excellent job restoring my home after a major water leak. Returning home from work to discover over an inch of water on the main floor and two inches in the basement is a very disheartening feeling, trust me. But DG Allen Construction came in and provided a well reasoned estimate that my insurance company could not argue. They then completed an entire remodel of the main floor and basement and we could not be happier with their work. More importantly they stand behind their work and ensured we were totally satisfied with everything. If you need a trustworthy and reliable contractor, I strongly recommend DG Allen Construction, and have too many friends for large and smaller projects.

D G Allen Construction Co.did outstanding job for addition to our house. They had excellent subcontractors for all specialty work (Foundation, Framing, Roofing, Electrical, Plumbing, HVAC, Drywall, Painting)They always supervised subcontractors work and made sure the quality and workmanship is excellent and clean up the area every day. They continuously kept us informed about activities ahead of time. Our project cost was vey reasonable. If you are fair and reasonable, they will be equally fair and reasonable. We are extremely happy with their work and highly recommend them.

Thinking about the process of having DG Allen build my new space, the words that first come to mind are excellence, integrity and decency. I would add to that fair and reasonable fees and dependability. I would never think of working with any other group again. The building process has just been a delight and a thrill.

DG Allen construction is professional, responsible, and an excellent company to work with. The company communicates during planning, permitting, and completion. They made me feel part of the team. I was nothing but impressed and will hire and work with DG Allen in the future.

We are very satisfied with the major addition of great room, full bathroom and bedroom on main level. The project was completed with professional craftsmanship. We highly recommend DG Allen construction to anyone.

DG Allen Construction made a dream come true. Building dreams one project at a time that’s what they do.

I have used DG Allen Construction for several projects in my home. Their outstanding workmanship and professionalism from start to finish were amazing. The team was punctual, communicative, and clearly took pride in their craft. Every detail was handled with care, and the final result exceeded expectations. Highly recommended for anyone seeking top-quality construction with a personal experience.

We have used DG many times in the past and are an amazing group to work with! Fair pricing, through, and attention to details are their strengths! Barry A

We hired Greg and his team to convert our screen porch over to a Florida type room that we could use year round. This included many custom windows, flooring, ceiling, insulation, paint and independent HVAC. The exterior underneath also needed to be closed in and insulated. We are very happy with the finished project. The worksite was left clean each day and disruption during construction was minimal. I would highly recommend DG Allen Construction for any home improvement project.

Absolutely Outstanding Work – Highly Recommended! I recently hired DG Allen Construction to completely renovate the interior of my townhouse, and I couldn’t be happier with the results. From start to finish, the team was professional, communicative, and incredibly skilled. They transformed my outdated space into a modern, functional, and beautiful home. Every detail—from the flooring and lighting to the kitchen and bathroom finishes—was executed with precision and care. The crew showed up on time every day, kept the worksite clean, and always kept me in the loop on progress and any decisions that needed to be made.

Greg Allen is everything you want in a contractor builder. Conscientious, on time and even under budget. He built an art studio addition for me in 2017, a deck facelift in 2020 and a kitchen upgrade in 2024. Top quality work. Great communication and integrity. And just a really nice human! Greg’s son Jimmy is a chip off the old block, equally focused on delivering beyond the client’s expectations. Rick is the right hand man and meticulous is an understatement to describe his work. I will always call Greg first any time I need construction and home improvement work. It is a delight to get more than you expect. A very rare thing these days.

DG Allen construction was able to take our vision and make it reality. Our basement and bar turned out amazing from flooring to cabinets to the live edge bar top. We were beyond thrilled with the outcome. Highly recommend!!

I hired DG Allen Construction to do a complete master bathroom remodel. I'm in the commercial construction industry and naturally have high expectations. Not only did they exceed my expectations, they went above and beyond! The professioanlism they displayed was impressive, and they finshed before schedule with no change in originial cost. They should also be given credit for dealing with my very demanding wife during the project. I would absolutely recommend them without reservation.

Very professional and knowledgeable. Would definitely recommend them for all future projects.
