Lehigh Valley PA Composite Deck Builder
Many of our customers opt for composite decking, and for good reason. See why composite decking is such a popular choice, from its low maintenance and durability to its range of beautiful, long-lasting finishes. Let’s explore what makes composite decking a smart investment for your outdoor space.

Low Maintenance
Composite decks are a favorite for homeowners who want more time enjoying their deck and less time maintaining it. Unlike wood, composite decking doesn’t need regular staining, sealing, or painting to keep it looking its best. Just a simple cleaning now and then is all it takes to maintain its beauty, making it an ideal choice for those who prefer a low-maintenance option.

Eco Friendly & Looks Good
Composite decking offers a smooth, splinter-free surface that’s perfect for barefoot walking, making it a safer and more comfortable choice for your outdoor space. Plus, it’s designed to resist fading and staining from sun exposure, spills, and harsh weather, so your deck will continue to look great over time with minimal effort. We build with industry leader Trex’s deck boards.

Durability
Composite decking stands out for its exceptional durability, making it a smart choice for long-lasting outdoor spaces. Unlike wood, composite materials are designed to resist common issues like rot, warping, and insect damage. This means your deck will stay strong and look great for years, even in tough weather conditions, giving you peace of mind and a deck that’s built to last.

Smooth & Splinter-Free
Composite decking offers a smooth, splinter-free surface that’s safe for barefoot walking and also built to resist fading and staining. Whether it’s the sun, spills, or harsh weather, your deck will stay looking fresh and vibrant, providing a comfortable and low-maintenance outdoor space for years to come.

EXCELLENT Based on 42 reviews Posted on DaniTrustindex verifies that the original source of the review is Google. Trey and the team at Milltek Decking were absolutely fantastic from start to finish. Trey is a true professional who is incredibly knowledgeable about his craft and took the time to help us design a space that would fit both our vision and our needs. One thing that really stood out was how well Milltek coordinated with our concrete contractor to keep the project moving smoothly. Communication was excellent throughout the entire process, and the crew was efficient, hardworking, and delivered beautiful results. We chose Deckorators Voyager Mesa decking because we wanted a product that stays cool to the touch and will last for decades, and Trey was more than happy to work with the material we requested. He also provided great ideas that helped bring the whole project together. The quality of workmanship is outstanding, the pricing was fair, and the finished deck exceeded our expectations. I would absolutely hire Milltek again—but based on the quality of their work, I don't think I'll ever need to! If you're looking for a company that takes pride in what they do and delivers an exceptional finished product, I highly recommend Milltek Decking.Posted on maria kellyTrustindex verifies that the original source of the review is Google. Amazing job ! Fantastic attention to the smallest of details… I would use again and recommend 100%.Posted on Richard WasatonicTrustindex verifies that the original source of the review is Google. Milltek replaced my old 30-year deck with a new one with pressure- treated wood for the floor and Trex material for the railing and posts. They did a wonderful job, and got done in 2 1/2 days instead of the advertised possible 3 to 4 days to do the job. The guys were very professional, and cleaned up all the debris of the old deck. Would recommend them to others for similar work.Posted on Bryan McCuneTrustindex verifies that the original source of the review is Google. Tre and his team did a great job with my deck. They guessed the job would take around a month and they knocked it out in just under two weeks. They are very professional. I would recommend to family and friends.Posted on Lisa LanceTrustindex verifies that the original source of the review is Google. We recently had Milltek Construction handle a full deck demolition and reconstruction at our home, and we couldn't be happier with the results. From the start, their team was incredibly professional, and their communication was excellent! They used a dump trailer to keep the worksite exceptionally clean and hauled away all the debris seamlessly. The craftsmanship on the new deck is outstanding, and it feels incredibly sturdy. Highly recommend Milltek for your deck project!Posted on Jeffrey MackTrustindex verifies that the original source of the review is Google. We are very pleased with the work Tre and his team did for us. The porch posts and rails are beautiful. They showed up when they said they would. They were very nice and polite and even loved our dog. And they cleaned up everything completely. We will recommend them to our friends and family.Posted on JonTrustindex verifies that the original source of the review is Google. The team did a great job on my deck railing and stair widening project. Very professional, hard working, friendly.Posted on Terri DavisTrustindex verifies that the original source of the review is Google. Great experience with Milltek Decking. Trey was friendly and professional. He was quick to return calls when i had to leave a message. Answered all my questions. He was prompt when he came to do the estimate. Was scheduled for mid April but got a call to see if I would like it done earlier. Trey and his team arrived on a Monday. He estimated the job would be done Friday and it was despite the weather being uncooperative. All materials and debris cleaned up. The deck is beautiful. I would highly recommend them and I'm pretty particular.Posted on Donald NeesTrustindex verifies that the original source of the review is Google. Came out for the estimate on time. I gave them a couple options as we were not sure of the size we wanted. They gave me all 3 options in a timely manner and revised the final one twice all in a timely manner. Down payment and locking in start times was done on my phone. Very easy. They called to let me know when they were coming and showed up on time. professional installation and the crew definitely love what they do. Even worked through the snow. Highly recommend this family owned business.Posted on Tim PhillipsTrustindex verifies that the original source of the review is Google. Tre and his team were amazing to work with. The entire process went extremely smooth, and the end product was everything I could have asked for. From the beginning, Tre was very communicative and explained exactly how the project would work. Milltek handled the permitting and were always responsive if I had questions. Execution of the deck was completed on time and the quality was well worth the price. Their pricing was very competitive compared to other deck contractors and they were willing to work with me on any upgrades or changes as they came.The final look of the deck is better than I could have expected and I could tell the craftsmanship was above and beyond from start to finish. I would definitely recommend Milltek to anyone who needs a deck built and I will be using them in any future deck projects that I have.
