EXCELLENT Based on 19 reviews Posted on Carol Miller15/07/2025Trustindex verifies that the original source of the review is Google. Excellent craftsmanship all workers! Very respectful and quick, quality work done. Cleaned up after finishing! Thanks! Will and Carol millerPosted on dodgestang27/06/2025Trustindex verifies that the original source of the review is Google. Really top notch work and craftsmanship. Ask them to replace 4 sets of rotted out stairs on my existing wrap around porch as well as put a 'sun deck' addition on the side. Great work. They met our needed date for a big party as well as hand built custom railings to match the existing! Can't even tell the old from the new railings!Posted on joanne hochendoner03/06/2025Trustindex verifies that the original source of the review is Google. All I have to say is… “WOW!!!“ They exceeded my expectations! They went beyond the extra mile. At the base of the steps is a paver patio and they picked up the pavers to fix the landing so the last step was the correct height. They put gutters on the roof and buried the downspout underneath the walkway, then replaced the walkway and it looks better than it originally did! And so many more things that made it a wonderful experience. The first day I met Miles for the estimate, I sensed that I could put my trust in him and his company and what an excellent choice that was! I highly recommend this group.Posted on Russ Pandolfo12/05/2025Trustindex verifies that the original source of the review is Google. The team from Mount Joy was prompt, friendly, and even made suggestions that saved me money. When they found a problem with the house, they explained the fix, fixed it, then moved forward with the original plan. I would highly recommend them.Posted on stuart shifrin10/10/2024Trustindex verifies that the original source of the review is Google. Great total experience working with Miles and his crew. Really gave me the feeling of confidence that they would do the job to my satisfaction. It was a fairly small job, and not the lowest bid, but worth every penny. Thanks.Posted on Beverly Hunter22/07/2024Trustindex verifies that the original source of the review is Google. thank you for building this deck for me joy company. It turned out amazing. Everyone loves the deck. some of my friends will be headed your way thank you, Miss HunterPosted on Justine Cole30/12/2023Trustindex verifies that the original source of the review is Google. My sister had a BEAUTIFUL deck built by Mount Joy Company LLC over the summer. I needed a new deck, so she gave me their number and I called and spoke to Mr. Miles. We set a date for him to visit my home to take measurements, select the type of wood I'd choose, and of course the pricing. He was such a gentleman, very thorough and patient with my questions. I was satisfied with what we discussed, so I signed his contract! A few weeks later, on a Monday morning, Mr. Travis, (who kept me informed with phone calls and text messages), and his crew started the five day "makeover" of my deck, and I also had new rails installed on my front porch. Oh my goodness, Mr. Travis, his men, and Jake's work is absolutely BEAUTIFUL!!! These hard working men are the ultimate professionals from start to cleanup. I am more than happy!!! I'm getting lots of compliments from family and friends. My neighbors are loving my home's "new" look and are writing down Mount Joy's number! Mr. Miles, Mr.Travis, Jake, and the rest of your crew, "Thank You So Much!!!" I'll definitely recommend your company, your number is permanently stored in my phone!Posted on John D. Witiak01/12/2023Trustindex verifies that the original source of the review is Google. As my wife and I watched Travis and his crew build two decks and an adjoining pergola on the back of our three story Victorian home we were reminded of old world craftsmanship, from the first posts planted in the ground to the white primer and two coat blue painted decks and steps and two coat white railings and the the crowning glory of the pergola on each deck, connected to one another, behind which on the west was a mud room to match the lighter blue old world siding of the main house and boasting a door with fifteen lights on the south rear) wall, a skylight and a window on the west wall. Everything shining brilliant white in the morning sun, to which the lighter blue siding of the house provides the perfect backdrop to the brilliant white railings and two interconnected pergolas, all from which we will enjoy our view of our woods we created from a hall acre of our football field length property lawn over four decades and the view of distant hills of corn and soybeans that surround our tiny town (population under thousand since it’s creation in the mid-1800’s) which offers no skyscrapers nor the roar of rush hour traffic…. just the sweet chirps of birds to awaken to amid the nearly 24/7 near silence (the perfect home to return home to now especially looking forward to relaxing and dining and entertaining on our decks.,, Thank you, Travis and your awesome crew and thank you to Miles whose honesty and heart combined with knowledge of the ins and outs of construction detail, sold us above all other firms from the first moment he sat with us on our porch to discus particulars, including a firm price and reminded us that being bonded and insured, Mount Joy would honor all building codes for our own safety and most certainly would register the project with our county’s building code inspection division for our safety and piece of mind. John and MarianPosted on Linda Miller09/08/2023Trustindex verifies that the original source of the review is Google. I cannot say enough good things about Mount Joy Company. Travis and his brother, Miles, own and operate the company. From start to finish, the entire team were highly professional, listened to our questions and responded in a thoughtful manner, and were highly skilled in all that they did. They cleaned up each day and really wanted to make sure we were happy with the porch. One can tell that everyone working for this company takes enormous pride in their work. We were told the scope of the project would take three days. All workers were punctual and did not take breaks. I highly recommend Mount Joy Company for any household project, inside or out!Posted on a zmoda29/07/2023Trustindex verifies that the original source of the review is Google. A very friendly and responsive group. They were able to quickly modify a few things on our deck replacement when unknown conditions were exposed during demolition.

Our Top-Quality Custom Decks
At Mount Joy Company, we offer custom design and deck-building services designed to fulfill your vision and fit your budget for your outdoor living space. Whether you’re considering a traditional wood deck or a low-maintenance composite deck, we’ll build yours with meticulous attention to detail, so it lasts a long time with maximum durability and the least maintenance possible. Check out our gallery for recent examples of our work!
Your Deck Material Options
Traditional Wood Decks
Natural wood decking is classic. Options like cedar, redwood, pine, and tropical hardwoods are easily stained or painted to match your style, but require regular maintenance to prevent weathering and decay.
Composite Decking
Made from a blend of wood fibers and recycled plastic, low-maintenance composite decking like Trex and Timbertech resists rot, insects, and fading with very little upkeep. Composite decking also offers a variety of colors, styles, and texture options, making it a versatile choice for any relaxing outdoor space. While more expensive upfront, it looks great and lasts long.
Vinyl (PVC) Decking
PVC vinyl decking is the most expensive option. It is highly resistant to rot, mold, and insects. Available in a variety of colors and styles, a PVC deck gives your outdoor space a modern look with minimal upkeep. Many homeowners choose composite or PVC decking for its low maintenance and durability.
Aluminum Decking
Aluminum decking is incredibly durable and weather-resistant, requiring very little upkeep. It’s non-combustible and slip-resistant, making it a safe option. Despite its higher cost, it’s a long-lasting and robust choice.
