Using GLK for our deck and screened in porch was the best decision we've ever made! So happy all around! Great to work with before, during and after the build.

We searched high and low for a contractor to build a deck along the back of our house after putting on an addition the previous year. We self finished most of the addition so have a general idea of what certain house projects should cost when hired out. George was one of the (very) few who was able to give me a quote online, site unseen, with my measurements, as I already knew for the most part what we wanted.

He came for an on site quote and had a book of his beautiful previous work. We hired him that day. During the month of October 2018 George built us a lovely deck. We would recommend him to anyone considering this type of project. Plus, he's local to Alexandria!

I just wanted to relay a wonderful experience we had with George from GLK Custom Decking. We started talking with him last Fall about our tentative plans to replace our deck. He twice came to our home to listen to our "plans". He attentively listened, asked thoughtful questions, offered terrific insights and was never pushy. When I asked him for a cost estimate, he was very competitive compared to other bids. So, we decided in December that we'd hire him.

He told us he had a few jobs ahead of us in the spring, but he hoped to get to us by April. Well, he started on 21March and finished yesterday, 01April. We are thrilled with the outcome and the experience. He was always prompt, courteous and professional. He was great with our young girls and our puppy. He was personally onsite - directly involved in our project - all day, each day.

He blends architecture with artistry - he takes great personal pride in his work and does excellent quality, efficiently and reasonably priced. We highly recommend George! http://glkcustomdecking.com/

GLK was the second estimate we received. And frankly, we did not need to look further. George was very straightforward about everything that entailed the job from materials to costs and all the additional possible special situations. He asked me to choose the manufacturer of the materials and explained the pros and cons of the different brands he installed.

He built for us an upper deck with an enclosed screen porch and a lower deck. The work took place between the end of summer of 2014 and Fall of that same year. This was a very big job and he encountered issues with the soil and quickly kept us informed of what needed to be done to move forward. He was always on the job site as he is the owner and Carpenter. I would definitely recommend him for any deck job!

I would like to highly recommend GLK Custom Decking based on the phenomenal experience we enjoyed while our porch and deck were being constructed. To give a few details, the new deck consisted of a 400 sqft. covered porch with an attached 200 sqft. deck. The entire structure was built from pressure treated lumber and is elevated approximately 12 feet off the ground.

From our initial planning meetings, George provided ideas based on his vast experience in architectural design to create an outdoor space that surpassed what we had envisioned. During the build, his true attention to detail was unparalleled; from sanding every piece of wood (including 6x6 posts), to matching the grain lines to ensure the finish looked seamless and pleasing to the eye. George always had a positive attitude and was a pleasure to work with.

He is a true master of his craft and this can be seen in every inch of the finished product. If you would like any additional information, please do not hesitate to contact me.

We hired GLK to build a deck. We explained to Mr. Karsadi that we wanted a low maintenance deck. Mr. Karsadi was confident in both his work and the product he would be using. He chose Trex. A year after the deck was built, the boards began to buckle badly. We contacted Mr. Karsadi who came to look at what happened. He actually tried to charge us to repair it!

We then contacted the manufacturer of Trex. Trex confirmed (there is a stamp at the end of their boards) the boards installed on our deck were Not Trex. We also had three reputable deck builders look at the deck. All of them confirmed the boards were Not installed properly, thus resulting in the buckling. We have spent $3,000 to repair Mr. Karsadi's faulty work.

This was the lower portion of the deck only. It will be an additional $3,000 for the upper portion of the deck. The most infuriating thing was Mr. Karsadi's inability to acknowledge his faulty work and do the right thing and fix it.

I am absolutely shocked that GLK Custom Decking was never reviewed on Yelp for deck building. Let me preface this by stating that my purchase included a free standing 2nd story deck (20 x 12) with a wood substructure and a Trex Treehouse composite deck and railing with 6 ambient lights. Here was my experience throughout the process. 1. Sales Process - Best I have ever experienced for a large purchase.

I received quotes from multiple contracting companies. Every single one had a sales person visit the home and go through hours of sales pitches pushing for a contract signing that very same day. This was not the case with GLK. George Karsadi is the owner AND builder. He is also the one who came to my house for a free consultation and quote. There were no sales pitches, and he actually took the time to walk me through the building process.

No other contractor did that with me because the person they sent for the quote DOES NOT build the deck. George does. He took notes on my wants and desires and gave me a quote through my e-mail quickly. 2. Price - Not only did I love the personal attention provided by a small company, but GLK was by far and away the lowest price. Let's just say that the large companies were easily 75-100% more expensive.

For example, Transnational came to my house, and told me what I was looking for in a full composite deck would cost me $25K. Prince William Home Improvement told me a HYBRID deck (no composite posts/rails) would cost me ~$15K and a full composite ~$20K. Let's just say when comparing apples to apples, I spent 75-125% less than both those quotes. 3. Expediency - My neighbor went through a company called Sunshine Contracting in the Alexandria are and signed the contract well in advance of mine.

I moved into my new house on 09/26/15 and signed a contract shortly after. It is now 10/19/15, and my deck is complete with everything I wanted, and his as yet to begin. That speaks volumes. Overall, a fantastic and painless process working with George and I highly recommend him for ANY job you are doing with a custom deck or outdoor living space.
