Replacing Liner vs. Installing Fiberglass Pool
Fiberglass is a popular alternative to vinyl when looking to ensure waterproofing in your swimming pool. Fiberglass pools consist of a shell built off-site, which means a pro can install it on your property in as little as two days. Once installed, they tend to be more durable and prevent mold growth that can become a common problem for vinyl liners.
Of course, these advantages come with a cost. Fiberglass pools cost more to install, with an initial cost ranging between $21,000 and $39,000 compared to $10,000 to $20,000 for vinyl pools.
That said, the lifetime cost of a fiberglass pool may be worth the initial price. Unlike the sometimes expensive repair costs for vinyl liner pools mentioned above, these types of pools generally only need minor pool repairs that cost around $675 for most problems. You also won’t have to worry about replacing a liner when its lifespan has expired.
DIY vs. Hiring a Pro
The cost of a vinyl liner alone can be expensive. So, should you really hire a professional, which adds significant dollars in labor cost?
The answer depends on your individual situation.
When to Hire a Pro
You need a complete liner installation for your new pool.
You are unsure about the exact issue causing a leak or other problems.
You don't have experience working with vinyl liners specifically and the material in general.
The fix will be complex and requires significant time and expertise.
When to DIY
You have already identified the problem and know it’s a quick fix, like a small tear near the top of your liner.
You have significant DIY experience.
You’ve completed repairs of this nature before.Â
Some problems, such as wrinkling, do occur due to improper initial installation. To make sure you get it right, it makes sense to hire a professional. Over time, you become more familiar with your pool as well as the necessary maintenance and repair. But especially initially, work with a professional to install your pool liner.
FAQs
How long does a pool liner last?Â
A pool liner can last anywhere from 15 to 20 years, depending on your pool’s chemistry. If you keep your water balanced, your liner will last longer than if you don’t. For example, over-chlorination, too much sanitizer, and heavy metal buildup can contribute to a shorter lifespan.
Can you put a new pool liner over an old one?
It’s always best to start fresh rather than put a new pool liner over the old one. You will need to redo or re-groom the bottom of the pool base before installation anyway, so many homeowners choose to get rid of the old one and start anew.
