How Much Does Pool Liner Replacement Cost in Baltimore? [2025 Data]

While the cost of living in Baltimore is on par with the national average, pool services there fall within the higher end of the average range. In particular, pool liner replacement costs in Baltimore cost $1,812 to $4,310, with most homeowners paying $2,948. Actual costs depend on factors like the size of your pool and the liner type. 

The following details will play a role in the final price of your pool liner replacement. 

Baltimore Pool Liner Replacement Cost Factors

These are the major cost factors impacting the budget for your pool liner replacement.

Size

Pool liners take one to three days or longer to install, with bigger pools taking longer and requiring more materials. This chart gives you a general idea of the national average costs based on pool size.

Materials 

Baltimore experiences lows around freezing temperatures during January and February. Fiberglass and concrete pools with tile are excellent choices for durability and ease of repair, although vinyl can work as long as it’s properly installed.

Liner Type

The type of pool liner you need depends on whether you have an aboveground or in-ground pool. Overlap and uni-bead liners are popular for aboveground pools. Beaded liners work with either type but are commonly used for in-ground pools.

Beaded liners attach to a track on the pool’s wall, and while they’re the most costly, they’re the easiest to replace. Overlap liners are clamped along the pool edges, while uni-bead liners have a J-hook that attaches to the pool wall. Installers can cut the hook off uni-bead liners and use them as beaded liners.

Liner Thickness

If you’ve heard about vinyl pool liners tearing, you might instinctively look for thicker liners. The standard liner is 20 mil thick, and thicker options like 28, 30, and 40 mil are $300 to $500 more.

When the vinyl is too thick, the liner won’t sit flush against the pool, and gaps can lead to wrinkling, stretching, leaks, and damage. This issue is more pronounced when you have a custom pool with sharp angles and curves.

Due to low temperatures in the winter, a thicker vinyl that’s 28 mil thick or more can be beneficial since they’re less likely to crack during the thaw-and-freeze cycle. Consult with a pool pro and ask if a thicker vinyl will work with your pool shape.

Consider these additional cost factors when planning your pool liner installation.

Labor

The average for labor ranges from $1,000 to $2,500 for an in-ground pool and $250 to $800 for an aboveground pool. Baltimore’s pool liner costs are higher than the national average, so expect to pay on the higher side of the range. Since pools aren’t as common in Baltimore as in sunnier cities, pool services cost more due to the smaller number of pool companies in the area.

While most DIYers can tackle regular pool maintenance, hiring a pro to install a new pool liner is the best option. Hire a pool liner installer near Baltimore, Maryland, and they’ll handle all the details from start to finish so your liner doesn’t leak and lasts for years. 

Seasonal Considerations

The ideal conditions for your pool liner installation are a dry day between 70 and 85 degrees Fahrenheit. In Baltimore, that means your best bet is to plan the installation between late April and October. For the best rates, reach out to your pool liner installer as soon as possible. That way, you can get on the schedule during the off-season and avoid the summer rush.

Permits

Baltimore doesn’t require a permit for pool liner replacement. However, if your pool pro identifies needed repairs, permits may be required. Common issues found during liner replacement include corrosion on pool walls and leaks, which necessitate building, construction, or installation and replacement permits. Electrical and plumbing permits are required for issues with the pool's electrical or plumbing systems.

Taxes

Remember to add the 6% sales tax to your cost estimate.

Does Pool Liner Replacement Add Value to Your Home?

An in-ground pool can increase home value in Baltimore, but that assumes your pool is in excellent condition. Homebuyers may lose interest when they see a pool in poor condition because repairs and renovations can be costly. This is all the more reason to keep your pool in the best shape possible, which includes regular pool liner replacements.
