At Seal-a-Deck, we’re an eco-friendly company that’s strongly committed to reducing waste and saving money for our valued clients. In support of that commitment, we provide Massachusetts homeowners with expert wood deck check-ups, deck repairs, redecking services, and new deck constructions. It’s our policy to only recommend a complete deck tear out and rebuild as a last resort when, and only when, the existing deck’s substructure isn’t in good enough condition to safely support a new deck.

There will be times when a deck’s boards, steps, and railings are too worn out and damaged for regular deck repairs to be a worthwhile investment. But if the existing framework is still in good enough condition to structurally support a new deck, instead of a total tear-down and rebuild we usually recommend our redecking services to get it looking and performing like new again.

Redecking vs. a Total Deck Replacement: Which Should I Choose?

If you’ve updated your home’s exterior in the past few years, a redecking project is also a great way to refresh your tired old deck’s look using a different material; resulting in a brand-new deck for a lot less money! At Seal-a-Deck, we work with all kinds of wood redecking materials, including pressure-treated pine, cedar, mahogany, and Ipe. Or, if you’re looking for a deck that’s extremely low-maintenance, we can also rebuild using innovative PVC or composite decking materials!

Which Type of Deck Material Should I Use for My Deck Project?

Our Job-Tested Redecking Formula

Most existing decks were built with pressure-treated pine posts and framing because it resists dry rot, termites and other wood-boring pests very well. As a result, when we’re evaluating a deck for redecking purposes that substructure is usually still in good shape. At that point we can simply strip down the rest of the deck to its framework and rebuild, saving the average homeowner hundreds of dollars as opposed to building brand-new.

5 Creative Redecking Ideas Guaranteed to Impress Others

Here’s the job-tested redecking formula we use:

1. Once you’ve decided to place your trust in our redecking services, we will schedule a convenient time to get started.

2. All old deck boards, steps, and railings will then be removed with surgical precision to protect your home’s property.

3. Once the deck framing is completely exposed, our technician will inspect it carefully. There may be times when we will need to add some additional framework or repair the existing substructure before we proceed. This becomes necessary if the framing wasn’t done up to our high safety standards when the deck was originally built.

4. When the deck’s framework is ready, Seal-a-Deck’s team will start installing the replacement decking, while using hidden fasteners whenever possible.

5. Once the new deck flooring is finished, we will then put in new railings and steps. Seal-a-Deck also expertly installs deck privacy walls, rail lighting, and decorative post caps, so ask us to show you some creative design ideas for your home!

6. Once the redecking project is completed, you will have the option to sign up for our deck maintenance plan. If you choose to do so, Seal-a-Deck will then provide you with a lifetime warranty so that you can enjoy your refurbished deck worry-free for as long as you own your home!

5 Deck Maintenance Tips After Your Deck Project Is Through

Deck Materials We Use

Based upon your aesthetic, maintenance and budget goals, we can install these different types of deck materials:


If you’re looking for a way to combine longevity and economy, pressure-treated Southern Yellow Pine is a great choice for a wood deck. Pine is easy to stain, holds up well to normal wear-and-tear, and is chemically treated to resist rot, fungus and wood-boring bugs. But not all pine boards are created equal, as cheaper varieties have more knots, uneven graining patterns, and a tendency to twist and shrink because of moisture-retention. For that reason, at Seal-a-Deck we only use pine decking that’s graded at “choice” or above.

However, any grade of pine can still crack, warp and split. To prolong your pine deck’s life and appearance routine maintenance is required, starting with an annual power-washing. You should also apply a stain or wood preservative to pine every two to three years to ensure its look and longevity. Overall, a pressure-treated pine deck should last for decades when properly maintained.


If you really like the rich, warm look of natural wood, cedar is an affordable option. Cedar slowly absorbs moisture, which helps keep the boards from twisting and warping like cheaper materials. A cedar deck should last up to 20 years, but that lifespan can get shortened when used on ground-level or heavily shaded decks that dry out slowly. For it to retain its beautiful color, you should wash and reseal cedar at least every two years with a clear, water-repellent wood preservative.

But even when doing so, cedar decks that are over 10 years old tend to start showing signs of weathering. Cedar is also a softer wood that can splinter or dent when heavy objects, like patio furniture or grills, are dragged across its surface. Because of its appearance, longevity, and price, overall cedar remains a smart deck investment.


Historically used for home furniture and cabinetry, mahogany is a hardwood that’s become popular for wood decks because of its knot-free appearance, rich hues, and tight grain. Known for its unique coloration, mahogany varies from a reddish or pinkish brown to a deeper shade of brown. If left unfinished, mahogany will naturally darken. To protect its original coloring from weathering, the wood should be sealed with a good penetrating oil within two weeks of installation, and then every 12 to 18 months afterward.

Although it’s a bit pricier than other natural wood decking materials, homeowners we’ve worked with love mahogany because it looks luxurious doesn’t splinter, and naturally resists wood rot. Properly maintained, a mahogany deck can last for 25 years and still look and perform great!


Raised on plantations in South America, Ipe is a beautiful natural hardwood known for its tropical grain variations and exotic appearance. Because of its fine texture and interlocking grain, Ipe is also very structurally strong and resistant to fire, scratches, termites, and decay. Another important feature of this wood, especially for homeowners near the ocean, is that it stays slip-resistant even when exposed to moisture. And, if you like to walk around barefoot on your deck all summer long, Ipe won’t absorb heat from the sun’s rays!

Ipe boards are known for their deep rich brown coloring, with pieces that oftentimes have red and amber hues woven within. If you want your Ipe deck to retain a darker appearance, we recommend sealing it every year with a good penetrating wood oil. Because Ipe’s so durable, you can also simply allow it to age, resulting in a silvery gray weathered look. And although it’s the most expensive wood we install, an Ipe deck should easily last for 25 years or more.

Best Deck Materials to Use When Pests Are a Concern


If you’re in the market for a deck that’s really low-maintenance, a wood-plastic composite deck may be just what the doctor ordered. Made primarily of wood fibers and recycled plastic, a composite deck virtually eliminates the annual sanding, staining, and touch-ups that come with 100% wood products. And, as a low-maintenance alternative to all-natural wood, composites still deliver much of the same beauty, color and graining patterns. A composite deck will also hold up very well to the various weather conditions found in New England!

However, composite decks are not totally maintenance-free, and a good power-washing is still recommended every year. This mainly helps prevent mold and mildew, especially in shady, damp regions of your deck. Composite materials are also more expensive and heavier than most natural woods, and some products can start decaying because of their wood component. To give you a higher return-on-investment, at Seal-a-Deck we only work with high-quality composites that are backed by a 25-year warranty.


PVC (polyvinylchloride) is another extremely durable and virtually maintenance-free material we install. It’s also very moisture and fade-resistant, and PVC won’t rot, split or warp even in areas prone to heavy rainfall or high humidity. Although PVC is highly resistant to scratches, stains, and mold, it can still show signs of wear-and-tear over the life of the product. And even though manufacturers have done a nice job of capturing the beauty, colors and graining patterns found in natural wood, PVC still can’t match the aesthetics of a wood deck built with something like Ipe or mahogany.

A PVC deck should still be power-washed every spring to remove dust, dirt and other airborne pollutants. As the most expensive material we install at Seal-a-Deck, a PVC deck typically delivers an exceptional return-on-investment for most homeowners because of its unequaled durability, ease-of-maintenance, and the fact most PVC products come with 50-year to lifetime warranties!

Small Brick Walkways and Patios

As you expand your backyard and outdoor living space, sometimes small elements can add the perfect touch. Brick walkways and patios bring both character and texture to your outdoor design, bringing every element together. You can add an extra level of comfort for moving through your yard or create an additional space for enjoying the outdoors. Best of all, small brick structures are an inexpensive addition to your project, helping you complete your look without straining your budget. To start, we’ll determine the best place and pattern for your patio or walkway. Design options include basket weave, running-bond, herringbone, and other popular patterns. Brick ground structures use special bricks called pavers, which are less porous and more durable than those you see in walls or fireplaces. Since these bricks are placed directly in the ground and exposed to the elements, they are designed to withstand damage caused by moisture and use. Pavers are available in multiple colors and patterns, perfect for finding the design you need.

Once we’ve prepared and leveled the area that will hold your patio or walkway, we’ll add the pavers you choose to create a gorgeous addition that can serve as the finishing touch to your outdoor space.

Deck Design

When building a new deck or redecking your current space, design is always the first step. If you know exactly what you want from your new construction, we can make your dream a reality. If you’re less certain about the final result, we can provide suggestions, ideas, and even full designs to ensure your new deck fits every expectation.

At SEAL-A-DECK, we start every construction project with a brainstorming session that we refer to as the Discovery Call. We want to maintain total satisfaction from the very beginning of your project, so we use this call to gather information and preferences about your deck, including:

  • What you are hoping to get out of this new space (entrance, lounge, dining space, cooking space, etc.)
  • A ballpark budget that includes what you want to spend and estimated costs for the design you choose

Next, our team will come to your home to meet and go over the space in detail. We will evaluate how the existing design works with your home and space, using this information to optimize our plans.

Every SEAL-A-DECK design is then created and approved by an architect and engineer to guarantee aesthetic and structural quality. Once they have reviewed the design, we evaluate our product options. We choose our materials based on your preferences and how they work with your design, so you always have the highest quality deck.

Most importantly, we take care of all the permitting needed for your project. At SEAL-A-DECK, we build it so you can enjoy it.

Prior to calling to Seal A Deck, I thought that my deck may have to be replaced in order to ever look the way I wanted it to. Two days of work later my deck looks incredible. It is seriously beautiful and I am so happy with the result. All of the employees we dealt with were extremely helpful in answering all of our many questions. The gentleman that did all of the cleaning, treating and staining of our deck was professional and just did an amazing and thorough job with our deck. We really appreciated his hard work!
