Is Deck Blocking Necessary? Let’s Answer That

When building a deck, it is important to consider whether or not blocking is necessary for the structure. Blocking, also known as bridging, is the installation of additional cross-supporting pieces of lumber between joists.

It can help to strengthen guard rail posts, prevent mid-span joist bounce or deflection, and stop joists from twisting due to seasonal pressure treated lumber expansion and contraction.

While blocking is not necessarily required in all cases, it can provide additional support and stability to a deck that may be beneficial depending on the deck’s size and design.

This article will take a look at whether deck blocking is necessary when it comes to building an effective and successful deck.

Definition Of Deck Blocking

Deck blocking is like a shield- it helps protect your house from potential damage. Just imagine, it’s like having an extra layer of armor for your home!

This type of protection involves placing an object on top of the lower part of a deck to act as a barrier against strong winds and water that can cause wear and tear over time. It also helps reduce the amount of snow and ice buildup, which can be dangerous if left unchecked.

Deck blocking prevents debris from clogging up gutters and downspouts, while providing additional support to the railing system. This makes sure that everything stays secure and sturdy in all kinds of weather conditions.

With all these benefits, it’s easy to see why deck blocking may be worth doing. But before making any decisions, let’s take a look at some pros and cons associated with this process.

Pros And Cons Of Deck Blocking

Have you ever asked yourself if deck blocking is really necessary? Deck blocking can be a great way to protect your home from pests, but there are some pros and cons to consider.

Let’s start with the good stuff: having your deck blocked off makes it easier for homeowners to keep their outdoor space clean and safe. This means no more worries about animals getting in or out of the area around your house.

If you have small children, this could provide an extra layer of protection as well. Additionally, you won’t need to worry about any critters making a mess on your patio furniture or other items!

On the other hand, deck blocking can also take away from the aesthetics of your backyard. It may also create issues when trying to move large pieces of furniture into or out of the area.

And depending on how much work needs to be done for installation, it could end up costing quite a bit in labor costs.

Before deciding whether or not deck blocking is right for you, there are several factors that should be taken into account…

Factors To Consider

Deciding whether or not to block your deck can be like a crossroads. You have to weigh the pros and cons, but there’s also factors you need to consider before making your choice.

One thing to think about is how much time you’re able to invest in it. Do you have enough hours in the day to make sure everything is blocked off properly?

Blocking requires dedication and hard work so if you don’t feel up for that, then maybe this isn’t right for you. Another factor is cost – will blocking your deck fit into your budget or do you need other options?

These are just some of the things you should ask yourself when faced with the decision of blocking or not blocking your deck. It all comes down to what works best for you and how comfortable you feel doing it. Taking these questions into account can help guide you towards making an informed decision!

How To Implement Deck Blocking

Planning and putting in place deck blocking can be tricky. But, there are several simple steps that you can take to make sure it gets done correctly. Firstly, think about the type of materials you will use for your project.

Secondly, measure up exactly what space is needed for the blockage to fit properly. Lastly, consider how much time it will take to complete the task.

Creating a successful deck blocking requires careful consideration and precise measurements. Make sure you have all the right tools before beginning such as saws, drills and screws so that everything fits together snugly.

Additionally, check with local building codes if applicable so that your structure meets any necessary regulations or guidelines set out by authorities in your area. Decide whether or not you need help from professionals – this could save time and money!

Alternatives To Deck Blocking

There are several alternatives to deck blocking that can provide similar structural support and reduce lateral movement. Strapping is one option where a 1×3 or larger board is attached across the underside of joists every 4 to 6 feet from outside joist to outside joist.

This helps to hold the spacing and provide some resistance to joist rotation or flexing. Another alternative is cross bracing, which is done using 2×2 material mitered at each end and fastened to form an X between joists.

This helps to better distribute the top load from one joist to the bottom of adjacent joists under deflection. Finally, using a band or rim joist, or a header, as an alternative to end blocking is also acceptable under the International Building Code (IRC).

Frequently Asked Questions

What Is The Cost Of Deck Blocking?

When it comes to deck blocking, one of the main questions is: what’s the cost? Well, it really depends on a few things. For starters, how large is your deck? Larger decks may need more materials like lumber and nails–which can add up quickly! Plus, if you don’t already have tools like hammers and saws lying around at home, those will also cost money.

On top of the materials, there are labor costs that come with having someone build or install your deck blocks. Depending on where you live, this could be as cheap as a couple hundred bucks or run into thousand-dollar territory – yikes!

All in all, getting an exact number for what you’ll pay out of pocket isn’t always easy. But hey – when done right deck blocking can help ensure your outdoor projects are built safely and last far longer than expected. And who doesn’t want that?!

How Long Does It Take To Install Deck Blocking?

Installing deck blocking can be like putting together a jigsaw puzzle. It takes some time, but the end result is worth it! The amount of time it takes to install depends on how big your deck is and how complex the blocking plan is. Generally, it will take several hours for an experienced contractor to get everything in place.

They’ll need to cut each block and fit them into place, making sure that they are level and secured properly before moving onto the next piece. They also have to make sure that all pieces intersect with one another correctly so that there’s no weak spots or gaps in between them.

This step can add extra time if done incorrectly. Once everything is secure, then screws should be put in place around each block as added protection against movement over time.

Installing deck blocking isn’t something you want to rush through – it requires patience and precision to ensure that your project lasts for years down the line. Taking your time here will pay off when you’re able to enjoy your finished product knowing that it was built with care!

Does Deck Blocking Increase The Value Of A Property?

Did you know that adding a deck to your home can increase its value by up to 7.5%? That’s pretty cool! But does it also make sense to add deck blocking?

Well, the answer is yes. Deck blocking not only makes decks safer and more secure, but it can also increase the value of your property even further.

When done right, deck blocking adds strength and stability to the deck so that it won’t collapse or move in high winds or under heavy weight. This helps protect both people and property from any potential damage caused by accidents on the deck.

Plus, if you ever decide to sell your house, a well-built and safe deck will be an attractive feature for potential buyers – making them more likely to buy your home at a higher price than one without a strong and stable deck.

So while installing deck blocking may take some time and money upfront, it could pay off down the road when you come to selling your property – potentially increasing its value significantly!

How Often Should Deck Blocking Be Inspected Or Replaced?

Having a deck blocking installed can be great – it increases the value of your property, and helps keep its structure strong. But how often should you inspect or replace it? That’s what we’ll talk about today!

First off, inspecting is important: You need to make sure that everything looks good and there are no signs of wear-and-tear. This means checking for loose boards, broken railings, crumbling steps, etc.

It doesn’t take too much time but it’s really worth doing regularly. And if something does need fixing – then do it right away before any big problems arise!

Replacing deck blocking isn’t as frequent as inspecting it, but still needs to happen every few years. To know when exactly depends on a lot of things such as where you live (weather affects wood) or whether anyone in the house smokes (as smoke damage weakens structures).

Generally speaking though – look out for warped boards or rotting posts which will let you know when its time for new ones.

It’s always best to stay ahead of potential issues rather than having to fix something after its gone wrong – so don’t forget to check your deck blocking frequently!

Pay attention to the weather and any changes in your home life that could affect the structure and make sure you get into the habit of looking out for warning signs of wear-and-tear. Taking these simple precautions will help give your property added protection and increase its overall value!

Are There Special Tools Required For Deck Blocking Installation?

When it comes to deck blocking installation, there are some special tools you’ll need. It’s kinda like a puzzle that needs the right pieces!

First off, you’ll probably want a drill so you can create holes for screws and other fasteners. You may also need saws or chisels in order to make sure everything fits nicely together.

And don’t forget about things like screwdrivers – they’re essential for securing your deck blocking into place! Finally, if you want to be extra safe, make sure to get yourself some safety goggles too.

So when it comes time to install your deck blocking, make sure you have all the necessary tools on hand. This will ensure that your project is done safely and correctly. Don’t rush the job either – take your time and double check that everything is how it should be before tightening those last few screws!


Deck blocking might seem like an unnecessary expense at first, but it could save you a lot of trouble in the long run. It’s not something that’ll break the bank either; most deck-blocking projects cost less than $300. Plus, when done right, it can add value to your property and help keep your family safe!

The installation process isn’t too time consuming either. With the right tools and some basic carpentry skills, you should be able to get it done in just a couple hours or so. What’s more is that regular inspections are also important for making sure everything stays up to date and secure.

All in all, deck blocking isn’t as daunting as it seems – I’d recommend giving it a shot if you think it’s necessary! Even though it may seem like a hassle now, I guarantee you won’t regret taking this extra step later on down the line. After all, safety comes first – no matter what else happens!
