Deck building requires planning and preparation. Before you begin, check with your local building inspection office to see if there are any restrictions or requirements.

Most home improvement books recommend plotting footing locations with batter boards and string. However, it’s easier and faster to build a layout frame from deck boards or joists. This frame also provides a solid guide for marking and aligning post bases. Contact Deck Builder Stafford for professional help.

Choosing the right materials and hiring professional builders can significantly impact the cost of deck building. It’s also important to factor in the cost of any add-ons or customizations, as well as the price of labor. Many of these factors vary widely depending on the size, design, location, construction materials and any functional add-ons you want to include. For example, adding a pergola or hot tub can increase the overall cost of the project by up to 10%.

The first step in building a new deck is to prepare the area for construction. A contractor will typically remove any existing vegetation and grade the land to ensure a stable foundation. They may also install a waterproofing membrane and a gravel base to ensure proper drainage.

In addition, they’ll use a ledger board, which will be anchored to the house framing. This will require removing the siding where the board must go, and they’ll tuck flashing under the remaining piece of siding. This will prevent water from getting behind the deck framing.

Finally, they’ll install the deck posts. This process can be particularly challenging if you live in an area with cold climates, as frost heave is a common problem. To avoid this, it’s normally recommended that you install the deck posts 4 or 5 feet below ground level to protect them from the freezing and thawing cycles of winter.

Labor costs vary widely depending on the geographic location and local market rates for construction services. They’ll also depend on how complex the design is and if it requires second-story decks or unique add-ons. In addition, a permit may be required, which will add to the overall labor cost.

Materials

A deck’s design and materials determine its performance and durability. Choosing the right material can make or break your budget. Depending on the cost of the materials used, you may have to limit your deck’s features or find other ways to cut costs.

The frame of a deck is usually made from pressure-treated lumber such as pine, fir or spruce. It supports the planks that make up the rest of the structure. The planks can be wood, plastic or a composite material that blends waste wood fibers with recycled plastic.

Wood can be stained or painted to complement the landscape or match a home’s color palette. Cedar is a popular choice for its natural resistance to insects and rot. However, it is prone to moisture damage and requires regular sanding and staining to maintain its beauty. Cedar is also vulnerable to splinters.

Hardwoods like Ipe, Cumaru or Garapa are also an option for decking. While they are more expensive than softwoods, they are very dense and have a natural resistance to rot and insect infestation. They require extra handling and special hardware to install. Hardwoods are more durable than softwoods but they can be difficult to work with and are prone to cracking and splitting.

Some homeowners choose to use composite or capped composite decking for the surface of their decks. These materials are made from a blend of recycled plastic and wood fibers and are available in a wide range of natural-looking hues and grain patterns. They are barefoot friendly and heat resistant but can absorb water causing mildew. They are also more expensive than wood but over time they may pay for themselves through their longevity.

Design

Decks are often kept under lock and key, due to copyright concerns or competition, but if you’re lucky enough to work in a studio, it’s a good idea to ask older freelancers for some examples of their previous work. If not, there are plenty of online resources you can check out to see what other creatives are doing with their decks.

Once you’ve got a feel for the design of your deck, you can start planning the details. Your budget will play a major role in the overall scope of your deck, and it’s important to be realistic about what you can afford. You can use a deck design tool to compare prices on different components and view estimated costs with and without labor factored in.

A footing is a concrete slab that’s laid on the ground, and it supports the posts that carry the load of your deck. The number of footings will depend on your site, and you should consult a building department to learn about frost depth requirements in your area.

Besides the foundation, the ledger board is another crucial component of a deck. This board is anchored to the house framing by using joist hangers and forms the structural side of the deck against your home. To install a ledger board, first remove the siding to expose the area where it must go. Then, tuck flashing under the piece of siding that remains above this area and extend it down the side of your home to prevent water from getting behind the framing.

To make your deck more functional, you can also add railing and stair lighting. These features are particularly helpful if you plan on entertaining after dark. Additionally, adding plants and greenery can visually separate areas of your deck and make it more inviting.

Installation

When building a deck, it is important to follow the right installation steps. A mistake during the foundation process could compromise the structure of your entire deck and lead to premature structural failure. To avoid this, always take your time and make sure you have a clear understanding of the process.

The foundation of a deck is built using concrete piers that are driven into the ground to help spread the load over a larger area. The piers should be at least as deep as the frost line, which varies geographically. If you’re unsure of how to dig the hole for the piers, consult your local building department for information on how deep to go.

Once the footings are in place, a ledger board is attached to the house and the joists are framed out. Be sure to use pressure-treated lumber for this step. If you don’t, it will rot quickly. Then, a shear stud (also called a Nelson stud) is inserted on each low point of the beam, which will prevent the shear from bending and cracking.

After the frame is erected, joist hangers are fitted to the ends of each side joist and fastened to the ledger with 16d nails. Next, the joists are cut and fit to each other to form the deck floor. The joists should be staggered to avoid butt joints and to create a more appealing deck.

A fascia is then installed to conceal the joists and hardware with more attractive material. Be sure to measure carefully to ensure that all boards are straight, and that the gap is uniformly spaced. April suggests using a screw placement guide to maintain consistent screw placement, as well as using stainless steel screws over galvanized ones to avoid black streaks and to increase longevity.

Maintenance

When a deck is finished, it needs routine care to keep it looking good and functioning properly. Cleaning, staining and sealing, repairing damaged boards, and splinter-free railings are all important maintenance tasks. Regular inspections will help to spot problems and prevent them from escalating into major issues.

The deck joists and handrails should be checked for signs of wood rot and other structural problems. These should be repaired immediately to protect the safety of people using the deck. It is also a good idea to inspect the wood where the deck’s ledger board connects to the house for damage. If the wood is soft or presents water stains, it must be replaced.

It is a good idea to replace any loose or splintered boards as well. This will prevent the wood from further splitting or cracking. Loose nails and screws can become a safety hazard. They should be hammered in or screwed back in place. Deck railings should be able to support the weight of a person standing on them. If a railing is not stable, it should be replaced.

A good time to apply a stain or sealant is in the spring and fall, when the weather is dry. It is a good idea to apply an additional coat after the first year or two of staining or sealing.

Decks that are used frequently should be inspected more often than those that are not. In addition to the usual maintenance, it is a good idea to add a wood preservative to the deck to protect against mildew. A wood preservative can be brushed on, rolled on with a paint roller, or sprayed. If spraying is the method of application, tarps should be put down to protect plants, air conditioners, and other equipment.

Decks take a beating from weather exposure, use, and natural aging. Regular maintenance and prompt fixes help extend their lifespans.

A deck is a great place to relax, grill with family and friends, or enjoy a beautiful sunset. However, your deck can suffer from wear and tear over time due to foot traffic and the weight of furniture and people. This can cause the wood to crack.

While a small crack isn’t necessarily a big deal, it can allow water to seep into the wood and cause rot or insect infestations. Having your deck professionally inspected and repaired at least every two years ensures that these cracks don’t get worse.

Cracking is a normal part of the aging process for any type of lumber, but some woods are more prone to cracking than others. For example, softwoods like pressure treated pine and cedar can develop surface checking, which is a small crack that occurs on the outer surface of the board as it dries. It’s more common for hardwoods to crack through the center of the board.

Deck boards that are cracked through the center are often a sign of structural problems, so it’s important to have these repaired by a professional. To repair a cracked board, start by washing the area around it and then filling in the crack with wood filler that is graded for outdoor use. Be sure that the filler is spread evenly and reaches into the crack so it’s completely sealed.

If the board is rotting, it may need to be replaced entirely. This is a more complicated project that may require climbing on a ladder to inspect and replace the board. If you’re not comfortable with this type of work, it’s best to contact a Maryland decking company as they will be able to handle the job safely and effectively.

To help prevent cracking in the future, wash your deck and apply a wood sealer or stain to keep the wood protected from moisture and temperature changes. A sealer or stain also acts as a barrier against rot and insects.

Rot

If you notice any rot in your deck, it is essential to repair it immediately before the problem spreads. This can lead to structural damage and attract wood-eating pests such as termites, which will cause even more damage.

Dry rot is caused by fungi that break down cellulose and hemicellulose, which is the material that gives wood its strength and stiffness. As the fungi degrade these materials, wood becomes weak and eventually brittle. This is a serious issue, especially for the structural beams and joists of your deck.

To check for rot, look for long sheets of grayish mold on the surface of the wood or in cracks and crevices. The area may also be soft to the touch or feel spongy. If you notice these symptoms, the best test is to take a screwdriver and press it into the area – if it sinks in, it’s likely dry rot.

Wet rot is often easier to diagnose than dry rot because it’s typically confined to an isolated area of the board. Depending on the extent of the rot, you may need to replace the board. A professional will determine if this is necessary, but it’s typically more cost effective to simply sand down the board, stain or seal it, and then apply a water-resistant preservative.

Both wet and dry rot are caused by moisture, so it’s important to address any water sources that may be contributing to your deck’s deterioration. This could include a plumbing leak, gutter failure, sprinkler system issue or other areas where water is pooling on your deck.

Another way to help prevent rot is by using a pressure-treated wood that has a high level of preservatives. It’s also helpful to monitor your deck for signs of rot and perform regular cleaning and maintenance to reduce the likelihood that it will develop. If your deck does experience rot, it is important to contact a professional for assistance to ensure that the repairs are done correctly. This can ensure the safety and integrity of your deck for years to come.

Mold

Mold and mildew are unsightly, but more importantly they can create health hazards. Significant exposure to mold spores can cause a variety of breathing problems for people with asthma and other sensitivities. The fungi can also damage the deck surface and infiltrate stains and sealers, making it harder to restore.

If you notice a significant amount of mold or mildew growing on your deck, the best course of action is to clean it as soon as possible. A power washer is a great tool for the job, but it’s important to use it carefully to avoid damage to the wood. Dixon Pressure Washing recommends targeting the moldy areas, and using a spraying technique that allows you to control the flow of water. This way, you can prevent the water from hitting unaffected areas and causing damage.

It’s also a good idea to use a cleaning solution designed specifically for composite decks. These solutions will not only kill the mold, but will help to prevent it from returning in the future. If you’d rather not use a commercial product, a simple mix of vinegar and baking soda will do the trick. After pouring the mix directly on the moldy area, sprinkle baking soda and let it sit for 20-30 minutes. After that, scrub with a brush and rinse.

Another common problem for decks is dry rot, which can destroy the structural integrity of the support beams and joists. It can be caused by shaded areas that never dry or by leaking pipes, roofs, or gutters. Unlike mold and mildew, dry rot isn’t a surface issue, but instead affects the interior of the wood, leaving it warped and brittle.

The best way to spot dry rot is by looking for a spongy texture and a musty odor. If you notice these symptoms, it’s vital to contact a professional for repair as soon as possible. If the rot is severe, it may be necessary to replace entire boards.

Algae

Nothing spoils the look of nice timber decking like slimy green algae growth. It not only makes the deck look dirty and neglected, but also slippery. In addition, it can stain and damage the wood. While a deck covered in algae may be tempting to simply lather on a coat of paint for a clean appearance, it’s not a good idea. Painting over algae will only cover up the discoloration and make it harder to see, but it won’t kill off the spores that are responsible for the problem. If you do decide to paint, a bleach or fungicide should be used to ensure all visible spores are killed off before starting a new application of stain.

Aside from the fact that algae, fungus and moss are unsightly, they can also harm wood and contribute to rot. Moisture is the enemy of wood and, over time, can cause it to swell, crack, warp and rot. Algae, fungus and moss promote moisture buildup on wood and create conditions that are ideal for the development of these organisms.

If left untreated, a single spot of algae can spread and cover the entire surface of a wooden deck. To avoid this, a regular cleaning schedule should be adhered to. This includes removing all furniture and fixtures from the deck, sweeping and spraying with a pressure washer to remove debris and dirt that can facilitate the growth of these organisms. A high-quality deck cleaner should be utilized, as well as a scrub brush to get the job done.

Aside from removing leaves, pine needles and clumps of grass and dirt, a deck should be thoroughly rinsed with the garden hose after being cleaned to prevent water buildup or puddles that can be the perfect environment for the development of algae and other fungus and plant growth. Once the deck is completely dry, it should be swept again with a broom and the furniture and fixtures can be returned to their original locations. Regular cleaning will help to preserve the wood, extend its lifespan and reduce the need for costly repairs down the road.
