What is Pool Resurfacing?

Pool resurfacing is the process of replacing or remodeling the existing finish on a pool with a new and improved one. This may involve applying either plaster, quartz aggregate, sapphire pebble aggregate, fiberglass, or PVC membrane-based finish to the interior walls of your gunite pool. Pool resurfacing can help restore structural integrity and improve the look of your pool.

When it comes to gunite pools, resurfacing is an important part of regular maintenance and care. Not only does resurfacing keep your pool looking its, but it also helps prevent further damage from occurring due to wear and tear from continuous use. Resurfacing also makes swimming in the pool more comfortable and enjoyable due to the improved finish.

So, how much does it cost to resurface a gunite pool?

On average, it can cost anywhere from $1,500 to $10,000 to resurface a gunite pool.

In general, the more complex and extensive the project is, the higher your cost will be. It’s important to do research and find out exactly what type of finish you want for your pool and what the associated costs are. You may even want to consult with a professional pool service or contractor for an accurate cost estimate before beginning the resurfacing process.

How to Tell if Your Gunite Pool Needs Resurfacing?

The lifespan of a gunite pool is usually between 10-20 years, depending on maintenance and usage. If you’ve had your gunite pool for more than 10 years, it might be time to consider resurfacing. Here are some signs that may indicate that it’s time to resurface your gunite pool:

  1. Peeling or Chipped Pool Finish: If your pool has started to chip or peel, it’s a sign that the surface needs to be redone. It’s important to repair any chips or peeling as soon as possible, as this can lead to further damage and expensive repairs in the future.
  2. Discolored Pool Finish: If your pool has become discolored or faded, it may be time for a new finish. The original color of your gunite pool can fade over time due to sun exposure and chemical corrosion. A new finish will restore the original look of your pool.
  3. Cracks in the Walls or Floor: Cracks in the walls and floor of your gunite pool can cause serious damage. If you spot any cracks, it’s important to get them repaired as soon as possible and resurface the entire pool if necessary.
  4. Leaking and Water Loss: Gunite pools are designed to be watertight, so if you’re noticing any water loss, it could be a sign of poor pool maintenance or damage. Resurfacing the pool can help repair any leaks and ensure that your gunite pool remains watertight.

How Often Should You Resurface Your Pool?

When it comes to the cost of resurfacing a gunite pool, one factor that could affect your budget is the frequency you need to perform this service. Resurfacing is important because it renews the worn out surface and helps protect the shell from chemical damage. It’s recommended that you resurface your pool every 6-10 years depending on the type of pool you have and how much it’s used.

You may need to resurface more often if your pool is exposed to extreme weather conditions such as intense sun or heavy rainfall, or if it’s subject to frequent use. If your pool has a vinyl liner, it should be replaced periodically (at least every 7-9 years) to ensure the liner is in good condition and won’t cause leaks or other problems.

To avoid costly repairs and unexpected expenses, it’s important to devote time and resources into maintaining your pool regularly. This means brushing its sides at least once a week, cleaning filters and skimming the surface of debris. It also involves periodic testing of the water chemistry and applying protective chemicals, such as algaecides or chlorine.

Factors to Consider Before You Resurface Your Pool

When it comes to resurfacing a Gunite pool, there are several factors that will affect the cost. Below is a breakdown of what you can expect when budgeting for this project:

  1. Size of the pool: The larger the pool, the more expensive it will be to resurface.
  2. Shape of the pool: Some shapes are more complex than others and will require additional labor costs.
  3. Accessibility: If there is limited access to your pool, then you may incur extra charges for bringing in specialized equipment.
  4. Existing pool condition: The amount of work that needs to be done will determine the cost. If there are a lot of cracks and other damage, it may require more labor and materials.
  5. Type of surface: Different surfaces have different costs associated with them, such as pebble or aggregate finishes which can increase the cost.
  6. Location: Depending on where you live, local labor and material costs can affect the overall price of resurfacing your pool.
  7. Installation time: When resurfacing a pool it takes several days to complete the job. The installation time will depend on your contractor and budget.
  8. Professional Pool Contractor: Working with a professional pool contractor is essential to ensure the job is done correctly. Their experience and knowledge will save you time and money in the long run.
  9. Pool Chemicals: If you are using a chlorine-based product, you will need to invest in additional chemicals after resurfacing your pool.
  10. Additional Services: You may choose to add additional services, such as pool deck resurfacing or adding a new coping edge, which can drive up the total cost.
  11. Warranty: You should always ask your contractor about any offered warranties when hiring them for resurfacing your pool. This will help you protect your investment in case of any major problems down the line.

Cost to Resurface a Pool According to Finish Type

When you decide to resurface a gunite pool, the cost will depend on the type of finish. Generally speaking, there are three types of finishes available: plaster, quartz and pebble.

Plaster is usually the most affordable option, with a price range between $2-$4 per square foot. However, it does come with a few drawbacks. Plaster is porous, which means it is more prone to staining and scaling than other materials. It may also require frequent replastering due to wear and tear over time.

Quartz finishes are the next step up in terms of price and durability. Costing between $4-$7 per square foot, quartz can last up to 15 years before needing a resurfacing. Quartz is also more resistant to staining and scaling compared to plaster.

Pebble finishes are the most expensive option, at $8-$15 per square foot. They are the most durable, lasting between 20 and 25 years with proper maintenance. Pebble finishes are also the most resistant to staining and scaling.

When it comes to resurfacing a gunite pool, there isn’t one option that is best for everyone. It’s important to weigh the pros and cons of each finish type, as well as your budget, before making a decision. With careful consideration and professional advice, you can make the best choice for your swimming pool.

By understanding how much it costs to resurface a gunite pool, you can create an accurate budget and plan accordingly. With the right finish, you can be sure that your pool will look beautiful for years to come.

Additional Costs to Consider During Pool Resurfacing

When it comes to pool resurfacing, there is more than just the cost of materials and labor. Other costs to consider include:

  • Additional Pool Repairs – Depending on the age and condition of your gunite pool, you may need to make additional repairs before resurfacing. This could include fixing broken tiles, reinforcing aging steps, or replacing outdated equipment.
  • New Coping Stones – If you decide to change the shape of your pool, you may need new coping stones as part of your resurfacing project. This will add to the overall cost.
  • Replacement Filter System – Installing a new filter system can help keep your pool cleaner and reduce maintenance costs in the future.
  • Pool Deck Repairs – A pool deck can become worn and damaged over time, so resurfacing the area around your pool is often a good idea. This will usually include repairs to any cracked or uneven pavement.
  • Professional Cleaning – Before you start on the actual resurfacing process, it’s important to make sure the pool is thoroughly cleaned. This will require professional help and can add to the overall cost.

How Much Does It Cost to Resurface a Pool Yourself?

For many pool owners, resurfacing a Gunite pool can seem like an overwhelming project. But with some patience and determination, it is possible to save money by doing the job yourself. Here’s what you need to know if you decide to take on the challenge.

First of all, it depends on what type of pool surface you have. If it’s a Gunite pool, then the cost of resurfacing materials will be higher than for other types of pools. You may need to purchase a special gunite kit that includes mixers, trowels and other supplies. Prices for such kits vary widely, but can range from around $500 to over $2,000.

In addition to the supplies, you will also need tools such as a pressure washer or power trowel. A professional resurfacing job may also require specialized safety equipment such as respirators and eye protection. It is important to take these costs into consideration before taking on the task yourself.

How Long Does it Take to Resurface a Pool?

The process of resurfacing a pool can take anywhere from three days to two weeks, depending on the size and shape of the pool. If your gunite pool is relatively small and rectangular, it may only take a few days for skilled professionals to complete the work correctly. On the other hand, if you have a large or complexly shaped pool, it may take up to two weeks for the job to be done properly. In any case, you should expect to have your pool filled and ready for swimming within three weeks of starting your resurfacing project.

Of course, the length of time necessary for a successful resurfacing project is also dependent on the weather conditions in your area. If it’s raining or snowing, the resurfacing process will take longer as the pool needs to be properly dried and sealed before it can be filled. Also, depending on the type of finish you choose for your pool (such as tile or stone), extra time may need to be allowed for proper installation.

How Long Does a New Resurface Last?

When it comes to pool resurfacing, the longevity of your new surface is a key factor. A variety of factors can affect the lifespan of your new Gunite pool surface, but in general, you can expect five to ten years or more before you need to resurface again. The primary factor that affects the life of your pool’s surface is the quality of material used.

Premium, thicker pool resurfacing products such as Pebble Tec or DiamondBrite are much more durable than basic Gunite finishes and will last much longer. The climate where your pool is located also plays a role in how long the new Gunite surface lasts. In areas with extreme cold or hot temperatures, pool surfaces can deteriorate more quickly.


In conclusion, the cost of resurfacing a gunite pool can vary greatly depending on the size and complexity of your pool. The best way to obtain an accurate estimate is to hire a professional contractor to assess the condition of the existing surface and recommend the appropriate materials for a successful project. Understanding what factors influence the cost of resurfacing can help you budget for the project and ensure that your pool looks its best for years to come. With proper care, resurfacing a gunite pool can be an affordable way to keep your backyard oasis looking pristine.

Frequently Asked Questions (FAQs)

1. What is the best material to resurface a gunite pool?

The best material to resurface a gunite pool is usually an aggregate finish, such as exposed pebble or quartz. Aggregate finishes are more durable and able to withstand the wear and tear of chlorine much better than traditional plaster coatings. They also have a longer lifespan, so they can be used for several years with minimal maintenance.

2. How do you know when a gunite pool needs to be resurfaced?

A gunite pool needs to be resurfaced when the surface has begun to show signs of damage, such as cracks, discoloration, or rough patches. Additionally, if a pool is more than 8 years old and its surface is starting to look dull and worn out, it might also benefit from being resurfaced. It’s important to inspect your gunite pool regularly and address any signs of damage quickly to avoid more costly repairs down the line.

3. Can you make an existing gunite pool deeper?

Yes, you can make an existing gunite pool deeper. Depending on the size and depth of the current pool, resurfacing your gunite pool could involve raising the bond beam (the wall around the edge of the pool), installing additional steel reinforcing bars to strengthen and stabilize the new walls, and pouring fresh gunite over all areas which need to be deeper. The cost of this process will vary depending on the size and complexity of the job, but it is typically around $20-$25 per square foot. It is important to note that in order to make an existing gunite pool deeper, you should always consult a professional pool contractor first.
